JRHT Derwenthorpe - Award-winning development in York

Technical solution: • An advanced timber panel system manufactured to provide a highly insulated fabric envelope • Careful attention was paid to junction details and assembly to ensure good airtightness, low thermal bridging, and fire safety • An integrated energy system was designed to optimise the use of micro generated renewable energy and reduce energy costs by minimising the use of grid electricity • The heating and hot water is provided by individual air source heat pumps with thermal storage • An integrated PV panel system was installed on the roof incorporating battery storage • A demand controlled ventilation system was installed to ensure good air quality • Remote access allows users to understand and manage their energy use and to access real time performance data.

Delivering outcomes: • Each home assembled on site within 3 days • SAP Energy Efficiency Rating 96 A • SAP Environmental Rating 97 A • Primary energy use 19kWh/m2 • Airtightness 2.7 m3/h.m2.
