Retrofitting existing homes for energy conservation: An economic analysis.

Examines the economic aspects of energy conservation techniques suitable for retrofitting into existing homes. Includes insulation, storm windows and doors, and weatherstripping. The object of this study is to determine that combination of techniques which will maximise net dollar savings in life-cycle operating costs for heating and cooling operations in existing homes, subject to specific climate conditions, fuel costs and retrofitting costs.

Criteria for retrofit materials and products for weatherization of residences.

Notes that many existing dwellings are inadequately insulated and in need of caulking and weatherstripping. Gives criteria for the selection of retrofit materials which are eligible for the Department of Energy Weatherization Assistance Program. Materials discussed are insulation, storm windows and doors, caulks and sealants, weatherstripping, vapour barriers, clock thermostats and replacement windows. Discusses the literature on retrofitting. Describes the different caulks and sealants available. Outlines precautions to be taken when applying different retrofit materials.

Retrofitting an existing wood-frame residence to reduce its heating and cooling energy requirements

Describes retrofitting a wood-frame residence in three stages to reduce its energy requirements for heating and cooling. The three retrofit stages comprised reducing air leaks; adding storm windows; and installing insulation in the floor ceiling andwalls. The house was extensively insulated to evaluate energy savings and changes in air infiltration rates. Concludes that retrofits produced only marginal reduction in air infiltration rates and attributes this to the original tight construction of the house.
