Renewables installed by Be Green for new house in Radlett has won the acclaimed International Property Awards for

Best Property Single Unit in the UK Leading interior design and build firm, Living In Space, is delighted to announce that it has won an International Property Award 2014/15 for its signature eco development in Radlett, Brickfields.

Be Green were appointed as the renewables installer after working closely with the

building contractor and the M&E consultants appointed to complete this prestigious development, we designed, installed and commissioned the heating and cooling system. This complete eco (Renewables) package significantly contributed to Brickfields wining this prestigious international award, see picture of Plant room on next page.

The heart of this wonderful new home are two Vaillant Ground Source Heat Pumps providing all the heating for the house, hot water, Swimming pool water and pool Air, the heat pumps ground collector comes from over 4 Kilometers of ground pipes installed in an adjacent farmer’s field.

The company, Living In Space, has historically worked with celebrity clients in London’s most exclusive areas, was awarded the prestigious accolade at an official ceremony at Marriott Hotel Grosvenor Square on Friday 24th October 2014.

Brickfields, Living In Space’s premier new build project, has been commended in the Development Sector category, as one of the first properties to truly merge eco living and high-end design, leading the way for sustainable development.

Living In Space incorporated the latest sustainable technologies seamlessly into the property design and the exterior is sympathetic to the home’s rural surroundings too; the striking combination of tessellated brickwork and glass pay tribute to the site’s history as a former brick maker’s as well as helping the home achieve its low carbon status. All bricks were handmade and locally sourced while the glass walls were designed to reduce dependency on heating and allow for beautiful light and open interior spaces, maintaining a close connection between the outside and inside.

Anita Kohn, Director of Living In Space, comments: “We are thrilled to have had our first development chosen for this prestigious award. It was always our intention to use Brickfields to communicate that there doesn’t have to be a compromise between luxury and eco living. Careful planning and utilisation of innovative technologies has led to the creation of a beautiful family home that doesn’t impact the environment. We hope that with this award, Brickfields can continue to be a prime example of much-needed sustainable development.”

The award for the Property Single Unit category is recognition of one of many outstanding schemes that the skilled Living In Space team has created since its establishment in 2001. Entrants for the category were judged against a strict set of criteria and the company was up against a number of high-profile developers in the county.

The Award winners’ logo is recognised as a symbol of excellence throughout the industry.

This award could be the first of many as Living In Space also has the chance to represent the UK in the International stages of the Awards. Later this year, the highest scoring winners from the UK Property Awards will be considered with other regional title-holders in Asia, Africa, Canada, America and Europe to find the ‘World’s Best’. This was announced at the grand final gala presentation at the Jumeirah Madinat in Dubai on Thursday, December 4th, 2014, although Brickfields made the short list for Worlds Best it unfortunately did not win.

The Awards judging panel consists of over 70 highly respected experts from all over the world and is chaired by three active members of the House of Lords: Lord Caithness, Lord Best and Lord Courtown. Stuart Shield, president of the International Property Awards, said he was “delighted” to celebrate the achievements of UK developers, commenting, “If anyone needed any evidence that the UK is in good shape after the problems of recent years, they only need to look at our UK award winners and see the stunning developments across the UK.

Developer in South Bucks decides Renewables is the only way forward

Mentmore Homes are a prestigious developer based in Gerrards Cross, Bucks, they build large bespoke luxurious homes to sell and for private clients.

For the development pictured Be Green has installed a heating and air conditioning package working alongside of a 4kW Solar PV array. Each of the system uses little or, as in the case of cooling, zero energy to cool the home, or cooling for free. I think probably the best way to describe what and how we do things comes from the testimonial below by the companies Director Nick Peck.

Testimonial

At Mentmore Homes we pride ourselves on achieving a superior product to the norm. We use cutting edge technology with the most beautifully crafted finishes to our prestigious properties. We carefully select our contractors with the most experienced and knowledgeable trades being awarded the contracts.

Be Green Systems have now completed 3 large projects for us with the fourth on the drawing board. After meeting Garry Woods we were very excited and a little cautious of what we were sold with reports of other systems not working correctly, all doubts were quashed once seeing the Be Green Heat Pump System running. The design of the system is paramount to performance, and Be Green are the experts in this field. There is more than enough heat to cover all eventualities (8 bedrooms along with 10 bathrooms!) and cooling the whole house too. We have also been very impressed by the products that have been employed such as Solar PV Panels, low energy pumps along with their workmanship in the plant room. The heating and cooling from the heat pump system is simply incomparable to a conventional boiler system non ventilated property. The living environment is cleaner, more comfortable, more efficient and most importantly chilled to your desired temperatures. All in all it makes our homes a better place to live.

Be Green know all their products inside out. They are punctual, on budget, polite and helpful. If only all trades were as easy to work with.

As a luxury developer we will now employ Be Green to do all our future projects. We have found within the large domestic market our customers are all too aware of the environment and they are always delighted and enthusiastic to discover an environmentally friendly heating and cooling system has been installed. This is even better value with large yearly payments from the RHI to help compensate the initial outlay. A no brainer!!

Huge new 1,800m² Development in South Berkshire

After much scrutiny and due diligence of recent installations, Be Green was awarded the contract to design and install a complete environmentally friendly Climate Control System for this unique, very large modern new home. We will be installing the system throughout 2015 with development due for completion later in the year. Our complete renewable installation will be fully maintained by Be Green and comes with a full 7 year guarantee that is fully supported by all the manufactures involved.

Two Vaillant 38kw Ground Source Heat Pumps are being installed each connected to 5 x 130 meter deep boreholes. These will provide all the energy needs for the properties heating and cooling requirements, as well as potentially heating a swimming pool and pool complex located away from the main building.

To distribute heat into the property Under Floor Heating (UFH) will be installed throughout, the design and installation of this is fundamental to ensure the highest efficiencies are achieved by the Heat Pump. Designing the UFH to ensure it heats the home with the lowest temperatures possible. Consequently when the outside temperature is at -3°, the flow temperature to the UFH will be approximately 35°, ensuring the home remains warm and toasty even on the coldest days of the year whilst achieving the highest energy efficiencies.

Building the house to be air tight helps keep the heat load of the property as low as possible, Mechanical Ventilation and Heat Recovery (MVHR) is then installed so the home can breathe. This provides the property with a constant fresh, clean, filtered air that supplies the living areas whilst also extracting the hot smelly air from the bathrooms, toilets and kitchen areas. The MVHR is designed to achieve around one third of an air change in the house every hour. To accomplish this air change rate the MVHR is designed to work at approximately 40 to 50% of its capacity; this makes the unit more efficient and quieter as well as increasing the air temperatures entering the building, all of which help the efficiencies of the building and reduce heat load.

Cooling the house is firstly done by cooling the air entering the property through the MVHR, this is done via two Cooling Coils that are connected to the inlet or supply air ducts. This constantly cools the whole property with gentle background Comfort Cooling. At the same time when there’s a cooling demand, the controls automatically increase speed of the MVHR unit up to 70 to 80% of its capacity (achieving approximately two thirds of an air change per hour), this helps the cooling by increasing the air flow through the property.

The coolant that chills the Cooling Coils comes from the stored cooled ground surrounding the boreholes that are connected to the Heat Pumps; this ground has been cooled after a winter of heating and providing hot water to the property (see brochure Heat Pumps page 8 and cooling page 17). So by simply circulating the fluid in the boreholes we can retrieve this stored coolant, this will provide the whole home with all its cooling requirements at a cost of approximately 50p a day.

In addition to the background Comfort Cooling the property also has 16 rooms that will have Air Conditioning installed; these rooms are controlled by the same thermostats that control the UFH. So for example, if a room’s stat is set to 20° the UFH will heat to that temperature then turn off. If the room’s temperature continues to rise even with the Comfort Cooling on to 22°, then the Air Con comes on automatically to keep the room temperature below 22°. This 2° dead band always remains, so if the room temperature is turned down at the stat to 18° then the cooling comes on at 20°, easy. The aim being when a room’s desired temperature is set by our simple to use controls, it will keep it there, in effect creating a home with an automated renewable Climate Control system. The cost of running our complete cooling package including the Comfort Cooling on the hottest day of the year for the whole house will be as little as £1.50 a day, or free if Solar PV is installed.

After some months of cooling the stored coolant will slowly diminish as the ground re-warms, this rewarming of the ground we welcome as it helps the efficiencies of the Heat Pump for the forthcoming winter. But a warm ground of course reduces our cooling ability, which is not so good. So to ensure we achieve the correct temperatures required to offer a full Air Conditioning solution, the cooling of the house is tied in with the heating of the Swimming Pool, holding off the heating of the pool water until there is a cooling demand in the house. Only then when the house asks for cooling do we start heating the pool, thereby getting the greatest efficiencies from the Heat Pump as it’s both heating the pool and cooling the house at the same time. By doing this we can control the coolant temperature and store it to provide the Air Conditioning temperatures required of approximately 6° creating a perfectly balanced sustainable heating and cooling system.

The property has other energy and money saving items such as the borehole and treatment plant to provide water for the irrigation to the grounds, water to flush the toilets and fill the swimming pool.

In summary, the total Be Green system guarantees this wonderful new home will have a simple to use fully automated, environmentally friendly, Climate Control system. It constantly monitors the home gently heating or cooling the environment whilst changing the air movement to individual rooms to suit the circumstances. All this ensures the property is always either perfectly warm or cool whilst creating the most comfortable and healthiest possible living space. This is all controlled at the touch of a button on the room stat, as part of the home automation system or on a beach somewhere with your mobile phone.

Below are some estimated CO₂ and cost savings of heating and cooling the home on an annual basis, as well as and providing all its hot water, cost exclude the swimming pool and pool complex.

House heating cost for the year, heating demand 124,000kWh, cost of £4,340.00, CO₂ output 20.4 tons

Code 5 House for Large developer

This case study shows a 320m² code 5 house that Be Green completed for Weston Homes in January 2012.

After a great deal searching by Weston Homes to find an experienced contractor that could help with the design and install a heating and cooling system to code 5 specifications, they appointed Be Green. In collusion they felt we were the most experienced and best placed company to do the work and liked some of our innovative ideas that we would bring to this fantastic experimental development.

To the right is the stainless steel inlet tower (still with its

protective film on) of the Mechanical Heat Recovery Ventilation System. This is the entry point for the incoming air to the MVHR that leads to a network of ground pipes buried 1.5 meters deep in the ground. The incoming air is either pre-heated in winter or pre-cooled in summer the using only the ambient ground temperatures. Installing this alongside our comfort cooling coil (pictured below) that gets its coolant from the cold borehole (that’s connected to the heat pump) we can cool the incoming air in summer by as much as 15° with practically zero running costs, a truly environmentally friendly cooling system.

As well as the MVHR we also installed an incredibly small 6Kw Ground Source Heat Pump manufactured by Dimplex. Because the house is so well insulated this unbelievably small Heat Pump will provide all the heat for the property along with a Dimplex buffer and 400 liter hot water tank.

As part of the overall complete heating and cooling packaged installed also includes Under-floor heating throughout, Rainwater tank, Grey water toilets, Solar PV Panels and all the first and second fix plumbing. All the flow and return pipes installed were pre insulated to heat the heat loss to a minimum.

The Ground Source Heat Pump has a single 145 meter deep borehole of which we use to heat the house in winter and offer additional cooling in summer.

The house is set up so that everything is automated, once the room temperature has been set the whole system works the keep that room at the pre-set temperature, whether it needs heating or cooling. Increased heating or cooling is achieved at the touch of a button on the room thermostat.

New 600m² House in Ascot for local developer

After exploratory visits to existing installations Argowan Homes appointed Be Green to in install a bespoke heating and comfort cooling package into a new prestigious development in Ascot, contract value £82,000 and completed in August 2011.

The package includes a Vaillant 22Kw Ground Source Heat Pump connected to three 125 deep boreholes that all come back to a central chamber and manifold, this is then connected to the heat pump in the plant room via a single flow and return pipe (see picture middle right). This will provide the property will all its heating, hot water and cooling requirements.

The Heat Pump has a 500 litre hot water cylinder along with a 1,000 litre buffer tank. The buffer tank is this size because of the log fire (pictured top right) that sits as the centre piece in the main living room. When this real log fire is lit the fire puts up to 7kw of heat in to the living room and as much as 17Kw of heat in to the buffer tank, this heat is then distributed around the house via the under-floor heating. Along with the ambiance of a real log fire the real benefit of this is the heat Pump will not come on as long as the log fire is working as it will generate enough energy to heat for the whole house.

The house has under-floor heating throughout designed to work with a Heat Pump, it’s all installed within a concrete screed to help create a large thermal mass. Every room and area has full zone control to offer heating control and comfort.

To help reduce heat losses and add to homes comfort levels, a Heat Recovery Ventilation System has been installed (see picture), this is oversized for the property. Over sizing means we can run the MVHR at 50% capacity in winter, this gives a better heat exchange, lower noise levels and higher efficiencies. It also means the air movement can be increased in summer for higher levels of Comfort Cooling work with cooling coil that collects the coolant from the heat pumps boreholes.

Rebuild of a landmark house in South Bucks

The new owner purchased this landmark house following the initial developer going out of business; his remit was to build an environmentally friendly home for his young family to live in, completed in November 2012

Be Green we recommend and introduced to him through two different sources that had used our services before. He was clear from the outset of his budget constraints and was interested what we could offer that would fall within his budget.

Although there was enough land for a Ground Source Heat Pump we could not install it within budget so our recommendation was an Air Source heat pump manufactured by Danfoss. As well as the ASHP we were also contracted to install the Under-floor heating (UFH) throughout and the Mechanical Ventilation Heat Recovery system (MVHR).

Because we were awarded the contract at an early stage of the build it gave us the opportunity to design and integrate these three different technologies to work together creating a highly efficient home. Integrating these systems will make the home far more efficient than it would be if each were installed as an individual separate item, this is what we have done.

An Air Source Heat Pump gets its energy out of the ambient temperature of the air, so the warmer the weather the better they perform, this is why they are so good at heating swimming pools in the summer. The problem is it also works the other way, the colder the weather gets the more the performance drops off. So at temperatures of -3 and below the efficiencies can drop by 30 or 40%, this is why we oversize Air Source Heat Pumps to compensate for this drop off, however there are some things we can do to help.

What we have done is to install the UFH pipes closer together, especially where there is ceiling to floor windows, this lowers the temperature needed to heat the house. We also designed the extract vent of the MVHR to be directly behind the heat pump (see picture). This air will extract from the building at around 5 to 7° when the outside temperature is at -3, this relatively warm air will help the Heat Pump achieve a higher performance as warm air is being blown over it, we estimate it will improve the effiecenties at -3 by around 10 to 15%, it will also reduce the need for the Heat Pump to go through a defrost cycle making further savings.

Total renovation of 1930’s Mansion in Richmond

The new Austrian owners of this wonderful very large home purchased the property with the aim of a total renovation that was to incorporate all the latest insulation and heating technologies, completed in June 2014.

After going through the various heating options available to them we settled on a new 50Kw Boimass Boiler to heat the house and provide all its hot water. The boiler was to be located in the basement of the pool house that is approximately 70 meters away from the main house. The boiler would also serve as the main heat source for a second house on site that when completed will be for the staff quarters.

The basement of the pool house has been split in two with 70% of the room dedicated the pellet store and the rest of it is where the Boimass Boiler is located. The boiler then delivers the heat generated through a series of Rehua ground pipes that move the heat from the plant room to the two properties. The insulation properties of the house have been brought up to greater standard than today’s building regulations along with the installation of a low temperature underfloor heating system. There is also been a Mechanical Heat Recovery Ventilation installed that works as a constant pressure system, so when electronic dampers open when the room is in use the ventilation speed increases to extract or add air movement to that room alone and does not affect the rest of the house. As the heat demand in the house has now been lowered to keep the house warm, the Biomass boiler will only need to give low temperatures to the house making the whole heating system more efficient, higher temperatures will be set for the hot water heating.

The house also has a Hydrogen fuel cell (pictured right) that will create over 13,000kWh of electricity from the natural gas supply to the house. This will generate most the power requirements in the property, the fuel cell also has a byproduct and that is it generates enough heat to keep the hot water up to temperature throughout the year, so the boiler need only top the heat up mostly during the summer months. This is ideal in the summer as we do not believe the Biomass boiler will need to come on as the fuel cell will provide all the hot water.

As this property is having two different renewable technologies it qualifies for the two government grants, the FiT’s and the RHI, these grants last for 10 and 20 years paying back the owners investment within 4 to 5 years as well as the reduction in energy bills that will be achieved.

New House in Middlesex has Be Green’s whole house heating and cooling solution.

Mr and Mrs Shah demolish their 1930’s 5 bedroom house and built this fantastic new 6 bedroom house to a very high standard on the same plot. Renewables and other energy saving devices have been installed as well as the latest high tech gadgets; contract value £88,000 and the building was completed in February 2014

Be Green have been involved in this development from the very beginning working alongside their architect before the house was even demolished. This enabled us to design our system into the very fabric of the house and offer our complete climate controlled heating and cooling system. Five rooms in the property have our environmentally friendly air conditioning system that is also integrated into the control system.

This 600m² house has a 17Kw Ground source Heat Pump installed to two 145m deep boreholes located under the front drive. To complete the plant room they also have a 500ltr buffer tank and a 700ltr hot water cylinder. We also installed the low temperature under-floor heating throughout as well as the Mechanical Heat Recovery Ventilation (MVHR)

The MVHR system installed is deliberately designed to be much bigger than required, it runs on normal mode at below 50% capacity, this saves on running costs, increases heat recovery and reduces any noise levels from the unit, it also means the ventilation speed can be easily increased to give greater comfort cooling to the whole house in summer. The cooling is automatic, when the house or certain rooms with the air conditioning reach a set temperature that room or the whole house comfort cooling comes on cooling the incoming air from the MVHR which also increases the air movement. The cool fluid for cooling comes from the boreholes connected the GSHP, where the stored temperature of the ground is 5 to 8° after the house has been heated all winter, the coolant is sent through a cooling coil attached the incoming air vent on the MVHR.

The coolant for the air conditioning also comes from the same boreholes, as the coolant cost nothing, it’s been stored, we set the system so that when the individual room with the air conditioning gets to a set temperature it automatically comes on keeping that room at the desired temperature.

The great thing about the cooling system is while cooling the house in summer its helps recharge the boreholes ready for winter making them warmer, and the warmer the fluid is coming into the GSHP the higher its efficiencies, a truly integrated renewable heating and cooling system.

Beautiful home in an area of outstanding natural beauty in Berkshire, this large 100 year old home has been slowly and lovingly restored back to its former glory by the present owners, as the last part of their refurbishment we installed:

A Baxi 30Kw Log burner with 1,600 litres of storage

A 16kW Danfoss Air source heat pump

Existing oil boiler to act as a system back up

All of the above to come on in order of energy saving, log boiler first, then heat pump and lastly the oil boiler, all to either heat the house, hot water and swimming pool

The Plant-room is 50 meters away from the main house

A 150 year old cottage brought back from ruin buy new owners, following completion of the home which included high levels of insulation Be Green were approached after they decided to install an outdoor swimming pool. We installed the heat pump to heat the pool water but and in addition to that it can also heat the house and provide all the homes hot water. As we are heating the house it now makes the owners eligible for the RHI (Renewable Heat Incentive) 7 year grant, our work consisted of:

A single phase Danfoss 13KW Air source heat pump

Existing Oil boiler to act as back up to heating and hot water

Heat pump to heat pool in winter and the house and hot water

Be Green are always open to try innovative new ideas like Rehau’s new Helix probes. Rehau is one of Be Green’s main working partners and we were asked if we would be interested in being the first in the UK to install this new ground collector (as picture) which of course we jumped at. These are a great alternative other types of ground collector like boreholes or horizontal loops. The probes pictured are connected to a small Ground source heat pump fitted to a renovated cottage in Sussex which included:

A single 8KW Danfoss Ground source heat pump

16 x Rehau Helix Probes each 4 meters deep
