Historic (long-term)
Independent data
A BRECSU sponsored monitoring programme [New Practice Profile 119] was conducted over the 1st year of occupation only (1998/1999)- something that caused some concern as this was the drying out phase of the buildings. We believed that the data would not fully represent the typical building performance. It was not possible to extend the BRECSU contract but the internal monitoring [started prior to BRECSU] has continued by HHP occupants themselves.
HHP recorded data
Max/ min temps [in one house] for porch, conservatory, main house and main house ground slab have been recorded together with an ‘ambient’ internal air temp [taken approx. 8am each morning] in order to give a realistic picture of the dynamics of temperature fluctuations in the houses. These are cross- referenced with temperature readings in the other houses.
