Notes that moisture problems could arise with improvements to thermal insulation of buildings. In addition indoor radon levels could rise. Considers the choice of heating system. Compares total costs of alternative systems. Treats the effects of increased insulation on internal environments. Identifies moisture sources. Stresses this should be regarded as only a limited guideline and that there is a need to ascertain the heat and mass transfer behaviours of building materials, particularly those that affect prediction of the transient behaviour.
A table is given which compares the performance, construction and function of the various types of window treatment. Aspects covered include sun control, thermal insulation, infiltration barrier, security and privacy, control by static, movab
