In terms of sustainability, the projects natural refrigerant CO2 credentials mean that the installation sits outside the F-Gas refrigerant phase out legislation and regulations. This means from a-users perspective, the installed Panasonic CO2 refrigeration system not only provides the highest levels of efficiency but also future proofs the site against any cost or availability implications resulting from current or future F-Gas legislation.
Since its European launch in late 2017, the Panasonic CO2 Condenser range has proven to be attractive to specifiers, with over 250 units now being installed across Western Europe and where a modular approach to medium and lower duty applications is required, as was the case in this application. Neil Bilton, Head of Key Accounts at Panasonic UK further explains more about the benefits, “The Panasonic range has been specifically developed for small to medium capacity applications within the retail and food service sectors and is particularly suited for installations in small supermarkets, convenience stores and garage forecourt retail operations. Furthermore, the range is also ideally suited to provide refrigeration within the restaurant and hotel sectors.” The units are compact, lightweight, have low noise levels (a range of 35.5 dB(A) to 36dB(A)) and designed to fit into smaller spaces with dimensions of (HWD) 930mm x 800mm x 350mm and weighs only 67kg. Panasonic is not new to this product range, having developed the latest version of the Panasonic CO2 Condensing units over time, with over 8,500 units being installed in Japan in approx. 3,700 stores since its launch in 2010 and thus building up essential knowledge and understanding of the end user experience and challenges. This solution helps to overcome some of the major hurdles that small retail outlets encounter with previous solutions that are currently on the market. The Panasonic units offer a stable and reliable system that helps to maximise energy efficiency with a low carbon footprint. Furthermore, the units can be set to run at low and medium temperatures with four initial settings which can be modified by turning a simple and user-friendly rotary switch to further enhance energy savings. Project summary: This project successfully delivered a natural refrigeration solution to meet the clients’ sustainability and efficiency requirements.
Garry Broadbent of Green Cooling further added “This type of modular installation is typical in terms of the direction that food retail stores and catering facilities are heading. Sustainable food retail refrigeration solutions are now required to future proof the operation of a site and remove any operational risks, resulting from the F-Gas HFC refrigerant phase out legislation, in terms of both refrigerant costs and quota restrictions.”
From a legislation and compliance perspective, the use of CO2 in the above installation removed the need on this site for F-Gas reporting and hence there is also no inclusion required within the operators Green House Gas (GHG) report, as no F-Gas refrigerants are utilised.
In summary, within this application, the Panasonic CO2 units provided a practical solution which combined the highest levels of efficiency and practicality along with a value-based focus with regards to both capital and whole of life costs.

20 New Homes Installed with Panasonic Aquarea Air Source Heat Pumps
Spire View, Cambridgeshire, UK
Aquarea air to water heat pump, Residential
Aquarea
Marcel Cooper, Construction Director of James Developments commented, “We find that today’s prospective purchasers are far more aware of environmental issues, emissions and the need for their homes to be sustainable. Purchasers increasingly look for cleaner, greener homes and are far more mindful of potential running costs. By comparison, we installed air source heat pumps in a development of 36 homes about ten years ago but then, purchasers were not aware of the benefits and economies that air source heat pumps offered although they were all very pleased with the way the homes functioned once they had moved in. Now, information online and in the media has made the average purchaser visiting site today more aware that air source heat pumps are a desirable way to provide renewable heating.”
Tony Holland - Southern Area Account Manager for Oceanair added, “Following the initial decision to go with the Panasonic systems, we had various meetings with all parties to agree on all aspects of choosing the correctly sized system and position of each individual install at Spire View, deliveries to suit the progress of the development and full training for all the engineers working on this side of the project. This has been a team effort between Oceanair and Panasonic from day one when we witnessed the archaeological dig on site through to the installation of each system in the fully built residential estate and the final result of a very satisfied customer which we always strive to achieve and gives the most satisfaction”.
Spire View consists of 20 new high end executive four and five bedroom homes, with the four bedroom homes having one en-suite and a family bathroom while the five bedroom homes have three en-suites and a family bathroom so the adoption of large, high efficiency Panasonic Aquarea hot water storage tanks is the ideal way to provide a constant and abundant supply of domestic hot water for the occupants.
The Aquarea Monobloc is extremely energy efficient with a COP of 5.08 for the new 5kW range, is very quiet in operation and offers a superb and sustainable alternative to traditional boilers with zero emissions at point of use and a lower carbon cost than mains gas, oil, LPG and direct electric. Furthermore, all residents will benefit from reduced heating and hot water bills.
Marcel further went on to explain “after comparing the benefits and costs of air source heat pumps with a traditional gas boiler solution and the attendant cost of bringing a gas main into the site and installing all the service ducts and meter boxes etc., we came to the conclusion that air sourced heat pumps were more cost effective and beneficial for us, as the developer, for our purchasers and most importantly, for the environment.
Furthermore, we researched air sourced heat pumps currently available, often dealing with manufacturers directly but ultimately we were guided by Tony Holland at Oceanair, whose personal and attentive service, market knowledge and in depth product awareness led us to specify the Panasonic system which offered the optimum balance of high energy performance, perceived quality, an internationally trusted brand, good and approachable technical back up, advanced technology and a fair price.
Tony Holland of Oceanair further commented, “It is important, when buying a heat pump, to choose a reputable manufacturer who will provide a quality service, a comprehensive warranty and provide proper guidance about the buying and installation of heat pumps. The initial outlay of a sustainable heating system may be slightly higher, however buying from a reputable manufacturer will ensure a high-quality, long life product, low maintenance costs and the peace of mind that you’ve made an optimised investment. A reputable manufacturer will also have the confidence in their products to offer a comprehensive warranty, such as Panasonic’s seven-year warranty*1.”
Tony Lathey, Panasonic’s UK Air to Water Pre-Sales Manager further added “Up to 80%*2 of the energy generated by air source heat pump comes from the air, with electricity making up the remaining 20%, so not only is this an extremely cost-effective alternative, but it is also environmentally friendly. With increasingly volatile energy prices, an air source heat pump is a great option to reduce overall energy bills by up to 60% (when compared to fossil fuel alternatives).”
The Aquarea Mono-bloc line-up can maintain the heat pump output capacity until -15oC outdoor temperature without the help of an electrical booster heater. The range is designed and produced by Panasonic and among the technologies listed on the International Energy Agency (IEA) Blue Map, whose goal is to reduce CO2 emissions to half the levels emitted in 2005, by the year 2050.The Spire View Development is nearing completion (July 2019) with many of the homes now ready to move into.

Le Dolcezze Patisserie
Italy
VRF, Shops, Restaurants
PACi
It is thanks to this technology that the Panasonic PACi Elite range has been installed “Le Dolcezze", a patisserie in San Lazzaro, Italy.
Famous for its Neapolitan pastry, "Le Dolcezze" required a robust, high quality and reliable solution that would provide consistent heating and cooling on the shop floor, storage room and in the kitchen, where fresh pastries are prepared.
The building previously featured a residential air conditioning system. This unit was unable to meet and maintain the required internal temperature of 15°C, which is vital to the storage and preservation of raw ingredients. As a result, during an exceptionally hot summer in 2015, the owner suffered major losses due to the deterioration of the quality of his products, in particular the chocolate, which was to be used in the preparation of fresh cakes.
Installer, Mariani SRL, specified and installed the Panasonic PACi Elite range to provide a reliable, high efficiency and energy saving air conditioning solution.
The existing interior unit was replaced with the Panasonic PACi Elite single split system, the ideal solution where there is a requirement for temperatures ranging between 8°C and 24°C. The single outdoor units offer cooling capacities from 4.9kW to 18.5kW and incorporate a dedicated “wine cellar” function. This feature has been developed especially for commercial or industrial applications, such as "Le Dolcezze", where maintaining a consistent, cool temperature is key.
Additionally, the units incorporate DC inverter technology, minimising energy waste, and R410A refrigerant to reduce the unit’s CO2 emissions. The units are controlled via a Panasonic CZ-RTC5 remote control, enabling the user to monitor and maintain consistent air temperatures. This feature ensures that the owner is able to achieve the required indoor temperature to preserve the raw ingredients.
Panasonic PACi Solutions
The Panasonic PACi Elite range boasts a wide range of features that make it the perfect solution to the needs of challenging commercial and seasonal demands. Not only can the units provide continuous cooling, even when outside temperatures are as high as 46°C, they also provide heating when external conditions are as low as -20°C, and cooling when conditions are down to -15°C outside.
Boasting exceptional energy performance, the system ranks among the best in its class (SEER A++ / SCOP A+) and its inverter technology reduces power consumption and operating costs by 20%. This, combined with the use of R410A gas to reduce the unit CO2 emissions, ensures Panasonic PACi solutions offer market-leading efficiency.
The latest models in the series are not only built to the highest industry standards to ensure optimum efficiency, they are also lightweight. With a slim and compact design, these units are easy to install.
Panasonic CZ-RTC5 Control
The Panasonic CZ-RTC5 wired remote control is unique, due to its elegant design, its control of operation on demand and its display of live energy consumption. Operational information is shown on the built-in screen as images to facilitate the immediate understanding of energy usage. The text is available in five languages (Italian, English, German, French and Spanish), and the backlit display also makes it easily visible, even in the dark or in poor lighting. The main features of the CZ-RTC5 include the capabilities of timer programming, the selection of indoor settings, and the display of the energy consumption.
Monument Hotel
Barcelona, Spain
VRF, Hotels
ECOi
Barcelona-based installer, IJT Instalaciones selected Panasonic’s ECOi VRF recovery solution thanks to its high performance heating and cooling, discreet installation and energy-efficient capabilities.
The spectacular Monument Hotel, part of the Preferred Hotels & Resorts Collection, is housed in a neo-Gothic palace dating back to 1896. The hotel is situated in the heart of the city’s commercial, tourist, cultural and business hub, on the Paseo de Gracia – one of the most exclusive avenues in Barcelona.
Its exterior boasts a colourful polychrome facade, one of the most artistic and impressive on Paseo de Gracia, created from a combination of materials including exposed brick, stone, ceramics and wrought iron. Inside, the blend of space and modernist elements, with an emphasis on light and texture, creates a fascinating interior, crafted by architects Oscar Tusquets, Carles Bassó and Tote Moreno in collaboration with interior designer Mercè Borrell.
The Monument has 84 exclusive rooms and suites, which vary in size from 24m² to 85m², designed to showcase the building’s breadth and luminosity thanks to high ceilings and large windows. The interior design of each room includes details of brickwork on the walls, oak flooring and furniture made with natural materials that provide great warmth, harmony and visual comfort.
For the renovation project, it was vital that the air conditioning system could work in harmony with the hotel’s considered design, with fittings being discreetly disguised within the fabric of the interior.
Luxurious comfort with maximum efficiency
IJT Instalaciones worked closely with engineer, RF2 Enginyers, to install Panasonic’s ECOi VRF air conditioning system to service all of the hotel bedrooms across five floors. Designed to offer total comfort for guests, the ECOi VRF system is ideal for large commercial projects thanks to its adaptable design and energy saving attributes. The ECOi VRF also offers simultaneous heating and cooling capabilities, which saves both energy and costs, as warm air generated during operation can be extracted and distributed to other areas of the hotel for heating. This eco-friendly transfer of heat also supports the hotel’s overall sustainability objectives.
Moreover, the ECOi VRF outdoor units are very compact at just 1m² per unit and requiring only 10cm between each unit, taking up just a third of the space of a conventional hydraulic system. This is especially beneficial for a hotel such as the Monument, which is located in a busy city centre location where external space is at a minimum. The total exterior installation included four ECOi outdoor heat pump units and 12 ECOi VRF outdoor units with heat recovery.
Internally, each hotel room has been installed with ultra-slim M1 variable static pressure units, which have an extremely quiet sound level of just 25dB. These thin and discreet units have been installed within the very narrow false ceilings, so as not to interfere with the interior.
In the rest of the building, where the ceilings are quite low, concealed floor-standing R1 units have been installed within perimeter areas to provide powerful and effective air conditioning. The R1 units have been fitted without enclosures, so that they are completely concealed within the existing decor.
Intelligent control system
The hotel’s air conditioning is managed with Panasonic’s intelligent hotel controller system, which allows independent in-room temperature regulation, while also being connected to the hotel’s reception for greater efficiency and control.
A single digital thermostat located in each room allows guests to manage both the indoor air-conditioning unit and bathroom floor heating. The controller can also be pre-set with minimum and maximum temperature levels and specific scenarios such as ‘vacant’, ‘occupied’ or ‘day’ and ‘night’.
While the hotel rooms appear to be controlled by a simple, conventional digital thermostat, the complete system is much more complex. The in-room thermostats link to a KNX internet cloud control system via a Panasonic CZ-CFUNC2 adaptor, centralising overall control of every thermostat. With this centralised management system, facilities and building managers can monitor energy usage throughout the hotel and maximise efficiency and cost-savings.
Another element that can be integrated into the KNX cloud control system is the room reservation system. With this feature users can define different room statuses, for example "quiet room" and "room not booked". Combining this information with the status of "room occupied" and "unoccupied room" through key card intelligence, users can define a table of settings for each of the situations allowing them to further optimise comfort and savings.
At the Monument Hotel, Panasonic has delivered a sustainable and cost-effective solution through a winning combination of high-performance air conditioning and intelligent cloud control. The complete installation not only provides long-term cost and energy savings, but also discreet fittings that blend seamlessly into the hotel’s beautiful interior design.

Greystones
Marina Village Greystones - Ireland
Aquarea air to water heat pump, Residential
Aquarea
This project has resulted in Heat Merchants winning a Panasonic PRO Award for the second time in a row, as it was recently awarded Best Residential Project, alongside Bridgedale Homes.
Shane Duffy, National Commercial Heating Manager for Heat Merchants commented “we are delighted that the Marina Village project has been selected for this award. The Heat Merchants technical team worked closely with our clients Bridgedale and Delap & Waller consultants, to provide an excellent heating solution that will be efficient, low maintenance and provide high levels of comfort for the residents of these fantastic houses.
This project showcases excellence in overall heating system design using the latest technology from Panasonic to achieve A rated homes.” “Our vision for the Marina Village Greystones development was to provide the very highest quality of living,” says Tony McLoughlin of Bridgedale Homes.
“Energy efficiency was a key part of this. We wanted the most advanced heating and hot water technology that would ensure low energy bills for our residents while providing the very best solution to deliver maximum comfort. Panasonic’s Aquarea air source heat pumps exceeded every requirement that we set, and we know that homeowners who have already moved in are delighted with the solution.”
The Panasonic High Temperature (HT) Aquarea heat pump was paired with a pre-plumbed, combined 200 litre cylinder and 70 litre buffer tank for hot water storage, providing the residents of the Greystones development with constant heating and hot water all year round.
The system was chosen by the designer because of the expertise and technical support that Panasonic provides, as well as the reassurance that the Aquarea system delivers hot water at a constant temperature of up to 65°C without the need for a back-up system.
Due to the close proximity to the Irish Sea, and the unique environment of its beautiful coastal setting, Panasonic’s heat pumps needed to be protected against the corrosive effects of the high levels of salt in the air. Each system was therefore treated with a special coating developed by Bronz-Glow that provides corrosion protection and can reduce energy consumption to ensure longevity in terms of performance, maintenance and aesthetics.
The heat pumps were sized using a combination of Panasonic Aquarea Designer software and Heat Merchants Technical Design software to help achieve the overall A-rated Building Energy Rating certificate. The Aquarea system features a multiple zone heating and thermostatic valve control system for all radiators in the homes to help provide ultimate comfort, ease of controls and exceptional energy efficiency for its residents.
A resident on the Greystones development, Stephen Kavannah commented: “We have found at least a 50% decrease in our overall fuel bills since moving into the Greystones property and found the system to be efficient and reliable. We would highly recommend the Panasonic Aquarea air source heat pump.” To watch a video on this project, visit the Panasonic Aquarea profile on YouTube.

The project resulted in Crystal Air obtaining the ‘Special Recognition’ award in Panasonic’s prestigious PRO Awards.
The Panasonic VRF ECOi MF2 solution offers a compact space-saving design and low noise levels thanks to a uniquely constructed casing comprising of two compartments; the upper chamber which contains the heat exchange and the lower chamber to store the compressors. Additionally, the system allows for a non-stop operation during maintenance.
Ducted units have sufficient fan power to drive warm air from the roof of the warehouse building to the floor, with minimum noise disruption for this large open plan office environment. “The Panasonic MF2 range coped brilliantly” added Domnick Ward of Crystal Air.
The Energy Recovery Ventilator (ERV) of the MF2 system recovers 77% of the heat in the outgoing air, to deliver a more ecological and energy efficient building with the air conditioning load being reduced by approximately 20%, thus resulting in significant energy savings overall.
During the summer months the system allows for a purge during the night, allowing the cooler night air to be present for a fresh start to the day. Adding to the efficiency of the system, the number of ERVs running at any one time can be reduced depending on the number of people occupying the space, for example, during lunch times.
The system has a centralised controller that acts as a master scheduler, allowing full management of the entire space. In addition, each area within the space is fitted with ECO NAVI detectors to automatically reduce the energy consumption when rooms are unoccupied. User -friendly remote controls have also been fitted to give individuals the option to instantly adapt settings to suit.
Bob Gallagher further mentioned “We have been delighted with the level of support provided by both Panasonic and Crystal Air prior, during and after the project with our client Zalando being delighted with the end result”.

Hotel Atocha
Madrid, Spain
GHP
The interior of the ‘Only You Atocha’, located in front of the Atocha station in Paseo Infanta Isabel, is an installation by Lázaro Rosa Violán of a modest aesthetic mix, featuring cultural influences from around the world but creating the perfect balance between form and function. This unique hotel’s iconic style has been created by the interior designer by strategically placed scenarios featuring furniture from different eras and styles throughout.
As well as being a stylish setting, the hotel’s ambience is so comfortable thanks to the Panasonic air conditioning system. So much so, that this beautiful project has resulted in Lázaro Rosa Violán winning a Panasonic PRO Award for Best Panasonic Innovative GHP Technology Project.
The ‘Only You Hotel Atocha’ has 206 rooms distributed over seven floors: 114 Deluxe, 78 Premium, 12 junior suites and 2 suites, as well as a terrace completely designed and equipped to surprise and relax.
Additionally, the hotel has several inspiring spaces such as the ‘Mama Framboise bakery’, a bakery in the purest New York style along with the restaurant ‘Trotamundos’, offering fusion cuisine in a cosmopolitan decor that follows the influence of the Big Apple. And finally, ‘You Universe’ located on the seventh floor of the hotel has a large terrace and panoramic views of the city where guests can have a drink and enjoy the DJ’s live music sessions.
A project adapted to the needs and layout of a building that also sought to achieve maximum energy efficiency
This building with 13 floors (4 basements, ground floor, 1st to 7th floors and roof terrace) required a power solution of 838kW in cooling and 698kW in heating set by the engineer’s calculations. These values correspond to the hotel’s demand peaks, which can occur on certain summer and winter days respectively. For intermediate periods (such as March-May and September-November), demand was anticipated to be perhaps 70% lower than the summer and winter maximums. The engineer responsible for the project, the engineering department of El Corte Inglés, opted for a base solution of seven Panasonic GHP units, fed by natural gas with each connected to a hydrokit for production of hot and cold water at temperatures of 7°C / 12°C and 48°C / 43°C respectively, since the air conditioning is performed by indoor fan coil type units.
The demand for cooling by the GHP units is 469kW and heating of 560kW. The remaining power to cover the total demand of the building is realised with a traditional system of chiller and boiler respectively.
The production of hot and cold water for cooling and heating is turned into separate heat and cold collectors, completing the installation to four pipes with their corresponding hydraulic system, pumping groups, valves and fan coil elements.
The building control system determines whether heating / cooling must be covered by the gas, chiller or boiler heat pumps. The above is dependent on a series of external conditions so that the performance of the installation is optimised, controlling the cascade entry of the gas heat pump units, thus ensuring maximum energy efficiency for the hotel. In spring and autumn, half of the units will easily work in cold mode (with the subsequent use of a large amount of residual heat), while the other units work in heat mode.
Waste heat utilisation for free ACS generation
Thanks to the Panasonic GHP equipment, the recovery of residual energy from the exhaust gases and the cooling of the engine to preheat the ACS deposits of the hotel are used. Peak energy recovery occurs when all gas heat pumps work at 100% demand in cold mode. The energy recovered at that moment reaches 30kw per unit, delivering hot water to temperatures between 70ºC and 75ºC. Panasonic’s extremely efficient system is capable of delivering very good results for ‘Only You Atocha’ hotel. It has been estimated that the residual energy of the equipment can recover up to 82% of the energy needed to meet the hotel's demand for ACS. In principle, water is preheated with residual energy.

K Club, Co. Kildare
Ireland
VRF, Hotels
VRF
Panasonic has installed a comprehensive heating and cooling system in the new 70-bedroom extension to the prestigious and internationally-renowned golf resort, the K Club in Ireland. Working with installer Crystal Air and O'Connor Sutton Cronin Consultant Engineers, Panasonic supplied an energy efficient VRF system that both blended into the interior design of the hotel and provided a quiet and subtle heating and cooling solution.
Host to the 2006 Ryder Cup and 13 European Opens, the K Club attracts golf aficionados from across the world, with 2 courses designed by golfing legend Arnold Palmer. Guests staying in the hotel and spa expect the very best, to which the heating and cooling solution could be no exception. The system needed to be quiet, so it wouldn’t disturb guests sleeping in the bedrooms, and discreet, so as not to negatively impact on the luxurious look and feel of the elegant, exclusive hotel. It also needed to be flexible and easy to control, to cater for the varying requirements of golf fans from across the world.
“We are very proud of the work we did at the K Club,” commented Vincent Mahony, National Account Manager at Panasonic Ireland. “To be involved in such a prestigious project and provide a solution that exceeded the hotel’s expectations was fantastic. We focus on creating heating and cooling systems that are not only energy efficient and effective, but offer real comfort and control to the end user, and the project at the K Club is a great example of this.”
Panasonic’s VRF ECOi system provided the perfect solution for the K Club’s exacting requirements. The extremely quiet MM Ducted Indoor Units, designed specifically for the hotel market, ensured minimal noise disturbance, and the ultra-slim space-saving design offered an unobtrusive way to deliver hot and cold air into the bedrooms without interfering with the aesthetic of the interior. Panasonic also provided an easy–to-use control panel in each room, so that guests had complete control over the operation of their air conditioning, allowing them to create the conditions that were comfortable for them.
Panasonic’s unique off-coil temperature control facility of its VRF system was crucial to the success of the project. Not only does it allow each unit to be controlled individually to enable personalised cooling for each room, but it ensures that the temperature of the air leaving the unit can be raised, and can be set at any temperature between 7 and 22°C. With warmer air leaving the unit, it eliminates cold air dumping and drafts, and ensures that overnight rooms don’t become too cold.
The K Club was keen to boost its sustainability credentials, and a key part of the project specification was that the cooling system must be very energy efficient. The Panasonic VRF 3-Pipe ECOi MF2 system, installed in the K Club, is optimised to provide maximum output with low consumption, with a market-leading COP rating of 4.76 and can offer simultaneous heating and cooling for up to 52 indoor units. The MF2 also takes up very little installation space, making it much easier for Crystal Air to complete the project.
Installation at the K Club was a significant challenge due to tight time constraints, and the Club’s desire for the building works not to intrude on the luxurious ambience. Walsh Mechanical, the contractors who carried out the project, were given 5 months to complete the installation in 70 rooms that formed the new extension to the hotel, a very short timeframe which they nevertheless achieved.
In order to avoid disturbing guests and maintain the peaceful atmosphere of the hotel, spa and golf course, Crystal Air and Walsh Mechanical were limited to certain areas at specific times and had to keep noise pollution to a minimum. To ensure that guests still enjoyed the 5-star experience while the construction was going on, contractors were kept out of eyeshot of the hotel guests. With all these restrictions on installation, it was essential that the heating and cooling system was simple and easy to install. Panasonic’s VRF ECOi system provided the perfect solution to meet the K Club’s exacting requirements for the hotel’s heating and cooling needs: energy efficient, quiet and discreet, and offering comfortable conditions for guests. Crucially, the Panasonic system is easy to control, with a very user-friendly control panel, so that guests are able to select their preferred climate easily.

Passive House, Poland
Poland
Aquarea air to water heat pump, Residential
Aquarea
Tomasz Lenarczyk, Sales Manager for Panasonic, Poland, said: “Aquarea heat pumps are perfect solutions for detached houses (and in this case a passive house). They are fuss-free and residents do not need to invest in other infrastructure. Our products are easy to install and non-disruptive. More and more people are opting for ecological and energy efficient homes – rightly so. It’s the way society is moving, and for that reason, Panasonic has designed new models of Aquarea heat pump, which meet the requirements of low-energy buildings. Not only is this solution seen here environmentally-friendly, but from the owners’ point of view, it’s also a much more flexible and cheaper than a traditional gas boiler”.
About the building
H1 is a model of detached house designed by innovative construction company, Procyon. The building covers an area of 147m2 and consists of four rooms and a kitchen. The simple, clean design of the building is complemented with a gable roof.
The property in Tychowo, built in summer 2013 according to the passive house standard, is the first building in West Pomeranian Voivodship to be passive-house-certified by the Passive House Institute (PHI) in Darmstadt. This certification means that the building fulfils numerous requirements relating to construction processes, implemented solutions and energy consumption. For example, passive houses must have good levels of insulation, an excellent level of airtightness, good indoor air quality and passive solar gains and internal heat sources.
According to the definition adopted by PHI, a passive house is a structure with a very low annual heating demand of approximately 15 kW/m2. Thermal comfort should be guaranteed by passive heat sources such as occupants, electrical appliances and incoming sunlight, and by significantly reducing the heat loss in a property.
The energy balance of the building is affected by many factors. For example, passive houses are compact in shape to minimize heat loss; windows should be south-facing or oriented toward the sunny side of the property; and interiors that require heat should be located in the central part of the building. It is also essential to use proper insulation materials of sufficient thickness for walls and roof.
Why is Aquarea a brilliant choice for passive houses?
The project team had to select the most energy-efficient and cost-effective home technologies in order to comply with passive house requirements and to complement the energy-conscious design of the building. Therefore, the characteristics of passive houses inevitably affect the choice of heating and cooling solutions. The objective is to maintain an optimal temperature for residents by heating the fresh air supplied to the premises via a mechanical ventilation system. Typically, project managers choose between a condensing boiler, heat pump and solar panels for the simultaneous provision of heating, ventilation and hot water.
The team selected a Panasonic Aquarea heat pump for the production of heating and hot water, thus maintaining the building’s energy-saving ethos. The heat pump is connected to a ventilation system and underfloor heating for maximum comfort and energy-efficiency.
An Aquarea heat pump specifically designed for passive houses
This H1 property is the first of its kind in Poland, comprising an Aquarea heat pump and water tank with a capacity of 200 litres. The temperature of each room is individually controlled using an IntesisHome remote control system (via a PC or smart device), making the system flexible and able to adapt to residents’ needs and preferences. Residents can control the system from anywhere in the world, as long as they’re connected to the internet.
This Aquarea heat pump (KIT-SDF05E3E5), specifically designed for energy-conscious houses, has a capacity of 5kW (A7/W35) and high COP of 4.63 (at nominal condition 7°C outdoor temperature, heating water at 35°C). Thanks to the A-class circulating pump with an inverter+ compressor, the system helps to reduce energy consumption and heating costs, in comparison to traditional heating systems. The unit belongs to the Aquarea T-CAP series and is able to provide hot water up to 55°C. It is effective even in extreme temperatures (-20°C to 35°C), and if the outside temperature falls below -15°C, the efficiency of the heat pump reduces by 0.8kW only, making it an extremely reliable product.
How can Aquarea heat pumps reduce heating bills?
Procyon recently carried out some research to analyse how heat pumps could help save on heating costs. According to the findings, the annual cost to heat a square-metre to 20°C is approximately 3.7 PLN. Please see how this compares with other heating systems in the chart above. The chart shows that biomass-pellet is the only heat source cheaper than Panasonic Aquarea heat pumps. However, biomass systems are more complex and require a customer to buy and store fuel, replenish the tank, and regularly clean the furnace. Biomass systems also emit by-products of combustion into the atmosphere. In contrast, heat pumps are a hassle-free alternative which require nominal supervision.
Aleksandra Szejny, R&D Specialist at Procyon said: “As the calculations clearly show, by heating a 145 square metre house with natural gas, approximately 4500 kg of CO2 is produced a year. However, with a heat pump, no products of combustion are released into the atmosphere and electricity consumption is low. Panasonic Aquarea heat pumps are a high performing, energy-efficient and low cost heating alternative”.
Make the most of RHI
Fife, Scotland
Aquarea air to water heat pump, Residential
Aquarea
In April 2014, the government placed a £650,000 fund into the Renewable Heat Incentive (RHI).
Already, almost 25,000 households across the UK alone have applied and started to benefit from the RHI. Thanks to the install of Panasonic’s reliable Aquarea 12kW Mono Bloc system, one family in Fife, Scotland, is now saving over £2,300 on annual heating costs.
Based in the small village of Balmullo in Fife, Scotland, an off-grid, medium-sized property relied on an old air source heat pump for an entire family’s heating and hot water requirements. This unique home had originally had all building materials imported from across Europe, in hope of producing the most energy efficient and sustainable home in the area. However, a combination of an old heating system, poor installation and product inefficiency, the homeowner had previously spent a costly £3,500 per year in running costs alone. This was reduced to £1,179 once Panasonics air source heat pump had been installed.
The family wanted a system which was both energy efficient and environmentally friendly, enhancing their unique eco-home which had been built with a view of saving money and reducing their carbon footprint. It was also important for the client to make use of available government grants, such as the RHI. Therefore, heating technology needed to be eligible and MCS accredited.
Local Panasonic PRO Partner and expert in renewable technologies, Eco Heat Renewables Ltd, chose Panasonic to facilitate the process of the RHI, supplying a “next generation”, sustainable and MCS Accredited Aquarea Air Source Heat Pump. This environmentally friendly domestic heating system from Panasonic offered a substantially improved performance in comparison to the previous system.
After a site survey was carried out and detailed heat loss calculations were completed Panasonic’s high performance 12 kW Aquarea Mono Bloc (single phase heat pump) was selected to meet the demand of the property.
Panasonic’s Aquarea range of air source heat pumps deliver tangible results for homeowners thanks to its quick payback in purchase and installation costs, along with enduring savings in energy and heating bills. Meanwhile, the Aquarea is popular with Installers due to its ease in installation and maintenance. Additionally, Panasonic’s Aquarea Mono Bloc adapts well in an existing installation with a boiler backup, and in new applications with under floor heating, low temperature radiators or even fan-coil heaters. This range holds many energy saving qualities such as an optional smartphone control for better heating and cooling management, and the ability to produce up to four times the amount of energy per kW consumed in comparison to conventional heating methods. For these reasons, Panasonic’s 12kW MonoBloc Aquarea system was the clear choice for all heating and hot water requirements for this property.
“Our client wanted a Panasonic heat pump as they felt that this was a strong, globally recognised brand, renowned for innovation, ease of use and reliability. They also wanted the system to be installed by a local company that was recognised as a Panasonic Pro Partner.” says Jim Russell, Company Director at Eco Heat Renewables. “We installed Panasonic’s Monobloc unit in June 2014. Feedback from the customer has been extremely positive and the family is delighted with the savings that were made immediately upon installation, and then continued in the following year.”
Within six weeks of the installation, the homeowner started to receive payments of £850 annually from the RHI. This would then continue for a period of seven years. In total, the £6,000 received from the RHI payments will cover 70% of the total install cost by itself.
As a result, Eco Heat Renewables successfully matched the clients brief and expectations. The family have lowered their original, daily running costs from £10 per day to just under £4, making savings of a massive 65% (£2,300 per year) and there has also been a substantial decline in carbon emissions.

Sunprime Atlantic View
Canary Islands, Spain
VRF, Hotels
ECO G, VRF
The exclusive Sunprime Atlantic View resort, owned by Thomas Cook, has 229 rooms plus full spa and swimming pool facilities. Holding an EU-Eco Label as testament to its commitment to the environment, Sunprime had set a goal to reduce its energy bills by 25%.
Its current heating and cooling system had proved to be extremely costly. Seven years ago, two large chillers had been installed to cool the rooms, whilst a gas boiler system heated the water, swimming pools and spa centre. Both systems were proving to be inadequate, with high running costs for the hotel plus customer satisfaction, claims about the fluctuations in water temperature for the swimming pools.
In search of a more cost and energy efficient system, five of Panasonic’s ECO G VRF systems were specified as they met all of the hotels heating and cooling needs via one simple solution.
Extensive development and research into the technology behind Panasonic’s ECO G system means these units use an engine cooling system, to heat water at up to 75ºC, covering all heating demands for the hotel. This includes all the rooms and most impressively, to heat the spa and outdoor swimming pool facilities, keeping temperatures at a consistent temperature of 28ºC. Additionally, Panasonic’s ECO G systems offered the ultimate ease of maintenance thanks to its remote monitor and maintenance software, which allowed the Maintenance Manager to control the status and temperature of the hotel from any site.
“Not only did the Panasonic system enable all of our heating and cooling requirements to be fulfilled through one compact system, but the installation itself was extremely quick, meaning the normal operation of the hotel was not affected,” explains Angel Hernandez Ramos, Resort Manager Sunprime Resorts. “Our customer satisfaction ratings have improved as a result of installing this system, which has meant an extremely quick return on investment for us.”
This new solution from Panasonic provided the hotel with energy savings so quickly that it was decided to replace the heating, ventilating and air conditioning (HVAC) systems in other Sunprime hotels across the Canary Islands, including Hotel Sunprime Riviera Beach & Spa, Arguineguín.
Within one year, Sunprime Atlantic View Hotel had made savings of 24% in electricity consumption and 32% in gas consumption, surpassing its original goals, thanks to a more efficient system by Panasonic.

GE Aviation
Bristol, UK
Commercial, Offices
PACi
For world-leading jet and turbo engine provider, GE Aviation, the solution could not have been simpler when specifying Panasonic’s PACi range of commercial units.
GE Aviation provides the crucial components and integrated systems for commercial, military, business and general aviation aircraft, and ship propulsion applications.
Bristol-based installer, Swift Express Maintenance Ltd, had worked with GE Aviation 20 years previously when the initial Heating, Cooling, Ventilation and Air Conditioning (HVAC) equipment had been installed. Now, this system was proving to be dated and inefficient to work across the 24/7 operation required.
Swift Express was asked to design and specify a solution with good efficiency capabilities, working to high demands and to the specific temperatures required for the heavy duty work carried out at this aviation headquarters. Therefore, identifying a reliable brand and product were essential for this install to avoid regular troubleshooting and repairs.
Panasonic's recently developed PACi range of indoor and outdoor commercial units proved the ideal choice for this application. Eight PACi Elite 14kW units were installed outdoors, whilst four under-ceiling units and four wall-ducted systems were established indoors. A further 28kW of PACi cooling technology have been specified to be installed within the factory.
Panasonic’s PACi Elite group of commercial air conditioning systems are ranked as one of the top COP values within the industry. Not only do the high efficient R410A refrigerant abilities result in the lower operating costs and reduced CO2 emissions that GE Aviation had specifically required, but all systems belonging to the PACi range ensure the ultimate ease in install whilst meeting the necessary safety approvals ensuring the utmost in quality and safety.
Due to the delicate environment and equipment handled by GE Aviation, a fire watch of 4 hours is required for any hot works, so Swift Express opted to use the revolutionairy Reflok aluminium piping system with the Panasonic equipment.
As part of Panasonic’s commitment to health and safety, all air conditioners undergo strict quality and safety tests before sale. This rigorous process includes obtaining all necessary safety approvals, to ensure that all air conditioners we sell are not only built to the highest market standards, but are also completely safe.
Initial renovations started five years ago when a 50kW air conditioning system was installed. The first phase of this new installation began in August 2014, which included the installation of 30kW of Panasonic PACi Elite air conditioning units. The Remaining 70kW of equipment was installed in the second phase, which started at the beginning of October 2014 and was completed by the end of the same month. So far, the installation has proved to require minimum in maintenance.
“Since the initial install five years ago, Panasonic’s heating and cooling systems haven’t stopped or had any problems,” explains Josh Muschamp, Business Development at Swift Express Maintenance Limited. “We have worked with Panasonic for many years and have never incurred any technical problems with its kit. This is why we chose to specify their range of PACi air conditioning units for this prestigious project. We needed something we could rely on to work to at high efficiency capabilities without requiring us to visit and fix every six months. We needed something that would be easy to install and would withstand compression bonding. With this in mind, for us, Panasonic was the obvious choice.”

Café 40
Spain
VRF, Restaurants
ECOg
Background
40 Café is the first café restaurant belonging to Los 40 Principales, in Spain's popular music radio station. The installation is within the basement of an old building in one of the busiest streets of Madrid. 40 Cafe, aims to become a new icon of nightlife in Madrid.
Challenge of the project
There were several challenges to implementing this project. The first was the power limitation in the building. Despite being in the Centre of Madrid, there was a restriction on power to run conventional HVAC installation. Another major challenge was the opening date. The tight deadline was a requirement to meet the demand of the owners. Outdoor units were installed at roof level with the help of a crane. Due to the limitations of restricting Street access and the imposition to residents of the building, the external installation was carried out in just one day available prior to opening.
The solution
ECOg, the gas powered VRF, was the ideal solution to overcome the power limitation of the area. The system combines seamlessly with Panasonic’s VRF indoor units and allows additional connection to a hydronic system. Panasonic pledged delivery of the units for the only day in which the crane could be used, in spite of the fact that the systems still had to be produced. The installation date was just 2 months after being awarded the project. This was all made possible thanks to the involvement of various departments as well as Senior Management, highlighting Panasonic’s commitment to meet customer needs.
Control
A touch panel with PAIMS management (CZ-256ESMC2), was installed for centralized air conditioning system control, including PC software and web server interface.
