Complete Property Energy Solutions

Both the winning and commended properties in the 2017 Salisbury Civic Society New Buildings Awards Scheme have been built by HHP Limited. The properties were recognised for promoting the highest standards of contemporary design in all aspects of the built environment within Salisbury and South Wiltshire. Both feature renewable energy based heating and hot water schemes that qualify for the Renewable Heat Incentive (RHI) and were designed by IBD Distribution for HPP through their Total  Microgeneration Scheme Certification Services (MCS).

The Lord Congleton Award for the most outstanding new building was given to Gold Hill in Tisbury which was recognised for setting the highest standards in building design, use of materials and architectural features. The owners’ appointed architects, sustainable energy advisors and contractor HPP have fulfilled their vision of creating a property within which the need for energy efficiency was considered with the same thoroughness as every other aspect of the building’s concept. This included ensuring it should be as green as possible and features high levels of insulation whilst also utilising sealed construction techniques for walls and ceilings.

These attributes have helped to reduce total energy demand for the propery to just 9kW, extremely efficient for a house of this size, and allowing the specification of an air to water heat pump (ASHP) for heating and hot water, rather than a fossil fuel based oil fired boiler.

In order to achieve maximum efficiency and a practical solution at Gold Hill that would qualify for the financial benefits of the RHI scheme, developer HPP turned to IBD Distribution. Their expertise lies in designing renewable systems that combine different technologies in the most effective way and for this property proposed a solution featuring an 11kW Daikin Altherma High Temperature Split System Heat Pump, a 300 litre thermal store, Daikin Solar Panels and IBD’s Envirotube underfloor heating system.

The MCS accredited, Daikin Altherma Heat Pump is eligible for funding from the domestic RHI scheme and would help the owners to offset the installation cost of the renewable heating system, making it a good long term investment. Like many other smaller developers, however, HPP does not have MCS accreditation and for their clients to benefit financially from the RHI scheme the renewable system needed to be commissioned to MCS requirements.

IBD, Daikin UK’s Specialist Renewable Distributor, does has MCS accreditation and provided HPP with a total MCS solution including guidance on installation and providing the commissioning service.  Andy Ham, Director of HPP, says: “ A complete renewable system designed by IBD and complete with the MCS service is the ideal solution for developers like us, now and in the future.”

The Daikin Altherma heat pump that was selected offers a solution for rural properties and was a viable alternative to an oil fired boiler at Gold Hill, fulfilling the sustainability aims of the owners. It has an A+ energy efficiency label,  providing the property with heating and hot water at a flow temperature of 65°C for central heating and storing water up to 75°C. The system includes the outdoor heat-pump which collects the heat from the outside air and transfers it to the indoor heat exchanger and on to the hot water tank. The heat pump is integrated with the roof mounted Daikin Solar Panels for heating the property’s domestic hot water.

HPP’s commended property in the awards was the Lake House at Swallowcliffe. It too relies on a renewable energy system designed by IBD and signed off to MCS standards. IBD designed a system featuring two 11kW Daikin Altherma Low Temperature Split Heat Pumps and Daikin Solar Panels linked to Daikin hot water cylinders and Envirotube underfloor heating.

Andy Ham concludes:” “IBD Distribution is the ideal partner for a builders like HPP to ensure clients have a renewable energy system that qualifies for the financial benefits of the RHI”.
