The above new building is described. Main features of this building are shade from trees, south windows catch the breeze in summer and insolation in the winter, insulated foundations, roof and wall insulation, solar collectors toprovide all hot water heating and 75% of space heating, thermally massive walls to stabilise temperature, various natural ventilation and air conditioning options, and storm windows. Energy consumption details are given.
Briefly describes a heat exchanger designed for use in a tight, solar heated house. The exchanger consists of three 3in. galvanized steel ducts within an 8in. galvanized steel duct. The ducts can be assembled in any length - 33 ft. was used in Provident House, giving a theoretical effectiveness of 33%.
Reports measurements of air leakage rates in the four energy-conservation research houses using the fan pressurization method. One of the houses is standard for the area and the other three houses have added insulation and vapour barriers. One house has a heat pump and one an air-to-air solar heating system. Air infiltration rates were measured in two of the houses using CO2 as a tracer gas. Discusses results and compares tracer gas with pressurization tests.
