Created as a joint venture between Scape and Willmott Dixon, Sunesis is an innovative approach to fixed-cost construction which delivers buildings for the public sector with speed, simplicity and certainty. The process also includes the latest renewable heating system from Mitsubishi Electric with three Ecodan CAHV monobloc air source heat pumps.
For every 1kW of electricity used to power an Ecodan CAHV air source heat pump, it delivers around 3.2kW of heat back to the building. Of that figure, around 69 per cent is renewable energy. As a result, the school qualifies for the government’s non-domestic Renewable Heat Incentive, receiving regular quarterly payments for the next 20 years.
The Sunesis formula provides project guarantees for quality, costs and timescales, ensuring the council stays in line with government dictates for public authority spending.
The renewable heating system is easy to monitor and control, in addition to being low maintenance. It can provide water flow temperatures from 25ºC up to 70°C without boost heaters. The air source heat pumps (CAHV units) guarantee hot water and heating all year round – even when the temperature is below freezing outside.
