Edinburgh World Heritage Site low carbon refurbishment
Winner of the Affordable Housing Development of the Year category at the 2009 Scottish Home Awards Winner of Inside Housing's 2009 Sustainable Social Housing Refurbishment Project This project was the final phase of redevelopment of the Caste Trades Hostel in the centre of the city’s World Heritage site. The project specifically tackles the difficult task of refurbishing an existing building to minimise CO2 emissions and dependency on non-renewable energy. To achieve this, Assist specified a Ground Source Heat Pump, with 70m vertical bores drilled into the bedrock to provide onsite renewable energy for hot water and space heating. We also designed south facing sunspaces for passive solar gain, combined with a positive input heat recovery system to minimise the requirements for a nonrenewable energy source. Finally, enhanced insulation was wrapped inside the existing stone fabric and secondary glazing added to the existing sash & case windows to minimise heat loss. Alongside this was a programme of extensive stone conservation and façade protection funded and monitored by the Edinburgh World Heritage Trust.
