Three different techniques for reducing exposure to microorganisms were tested during remediation of moldy buildings. Concentrations of spores (fungi and actinomycetes) were determined by filter sampling before, during, and after remediation. The local exhaust method used for asbestos dismantling was the most effective control method. In the construction zone, concentrations of microorganisms were 4-25 times higher during remediation than before it. In the adjacent area no increase in concentrations was seen.
The Manchester Project involved the energy efficient rehabilitation and retrofitting of existing housing units plus the construction on vacant lots of new dwellings incorporating energy conservation measures. This project, in the Manchester neighbourhood of Pittsburgh, Pennsylvania, began inthe late 19 70s and was completed in 1983. Energy use and air quality monitoring were carried out for one year after the completion of the project. It was found that in comparison to detached single-family houses using standard construction, energy savings of 75 to 80% were being realized.
The project involves a 'Housing for the Elderly' development of 32 units, built by the Blenheim Borough Council, BBC, under a Housing Corporation sponsored initiative. The initiative is aimed at providing affordable rental accommodation for the fastest growing section of the community: the elderly. The council sought a new housing design which catered specifically to the needs and resources of elderly tenants. Comfortable and affordable rental accommodation linked with low maintenance were foremost considerations in the project.
