Abstract:
The performance of three types of passive solar
feature has been studied; fifteen Roof-Space
Collectors on an estate of low energy houses at the
Milton Keynes Energy Park, 101m2 of Thermosyphoning
Air Panels at a county primary school in Nazeing,
Essex, and three Thermosyphon Solar Water Heaters
installed on a group of three terraced cottages at
Cranfield, Bedfordshire. Each of these passive solar
features was monitored intensively for at least one
heating season using dedicated data-acquisition
systems. The maximum specific annual solar
contributions to the auxiliary space/water heating
systems were 128 kWh/M2
,
78 kWh/M2' and 104 kWh/M2
respectively. The corresponding payback periods were
25,37 & 21 years respectively, on replication.
