10 Feb 2012: DNC writes: "I have returned the loaned camera now, but here are a few of the key pictures. Each picture tells a small story."
"DNC house back elevation. It shows that we heat the kitchen-dining room well, but leave the bedrooms unheated. Also, when there is no windspeed, the wall adjacent to the drainpipes gets warmed."
"Victorian semi-detached, lived in by a WB architect and his eco-campaigning wife. Ear elevation picture shows contrast between externally insulated and non insulated neighbour. Also the effect of an extractor fan. The front elevation photos is showing how much they need a door lobby! (the front walls are internally insulated)"
"Detached West Bridgford house (right) recently externally insulated with 100mm Kingspan and render. House on the left is solid walled. The house has the insulation continuing to below the ground, so there is no bridging, just a little tell tale yellow line to indicate the DPC line."
"A near neighbour's terraced stepped house, with PV solar panels above and cavity fill, but note the house next door, glowing brightly! Radiators against the wall are a thermal giveaway. The house on the extreme left? perhaps the neighbours are out."
"House in Lady Bay has had a 2 storey extension [Left] added to the existing house, [Right]. Extension has been built with solid wall and external insulation. Side wall of the existing house has been externally insulated [extreme right]. The bedroom above the front door has a giveaway radiator, and the front door needs a lobby and double glazing."
"Another of DNC's near neighbours has had house cavity filled last year, and it is working. The other half of her semi-D needs wall insulation, and to consider the wall mounted radiators."
"Large house in Musters Rd, but solid walled, with secondary glazing by Storm Windows. Central pane in upper bay window has been de-secondary-glazed specially for the camera to show the effectiveness of Sec-Glazing. Front door has no lobby, and a single glazed glass viewing panel. Entire house needs insulating (all walls are glowing slightly) but it would be a large and expensive project. "
"My house, SW corner external, shows heat loss around the window head, when that was being built, I was convinced that the builder wasn't taking care to close up the jamb correctly, and now I have proof."
"Same house SW corner interior… further proof. Builder promised that when the window was enclosed he would seal back the insulation correctly. Cavity insulation omitted! I am wondering whether to contact NHBC."
