The Milbrandt low-energy house was built in 1980 in Saskatoon as part of a demonstration project. This paper discusses temperature distribution using point-source heaters as the sole heat source and relying on natural convection for distribution of heat. Summertime overheating in low-energy houses was also studied.
A spun-bonded polyolefin air infiltration barrier (AIB) was installed immediately beneath the siding of a 5-year-old, ranch-style house [conventional comparison house (CCH)]. The AIB reduced the heating energy consumption by 24% over the remaining life of the house. This test confirmed earlier field studies and allowed the development of the mechanism by which AIBs function and the recommendation of required AIB physical properties.
This note arises from work to identify the effectiveness and cost of remedial treatments for condensation and mould problems in housing. Although the four factors - moisture generation, ventilation, insulation and heating - which control the likelihood of mould growths have long been established there hasnot been a straightforward way of showing their interrelationship, particularly where energy costs are important.
The use of heating and ventilation was measured in several flats to find the relationship between the two. Measurements were taken in 9 flats in a 6-storey block in Berlin, with various types of ventilation system. Two flats remained uninhabited to serve as a comparison. The duration of the opening of windows of the individual rooms lastd on average up to 15 hours per day during the whole heating period. The tenants' own evaluation of the duration of airing differed immensely from this result.
Building services accounts for some 40-50% of the UK's consumption of primary energy. The potential for energy saving through the adoption of such schemes as district heating, combined heat and power, heat pumps and solar energy could make a major contribution to the country's energy balance.
Domestic demands account for about 40% of total energy supplies in Sweden. This article reviews research by the Building Technology Division of the Swedish Royal Institute of Technology over many years into the thermal behavior of houses. It highlights the importance of effective insulation and of solar heat gains in particular situations, entailing modifications to conventional design calculations.
