Describes the retrofitting of 2 1930's semi-detached houses with insulation, draught-stripping, double glazing, heating controls and heat pumps. Measures performance and finds results compare with expectations. Simulates the heat gains equivalent to a family of four. Heat losses were slightly lower than predicted. Air leakage was also low.
Decribes how the 19 floor 76m high Arts Tower at Sheffield University is having its energy use characteristics investigated. Illustrates a typical floor plan. Describes and illustrates a component pressure testing rig todetermine the infiltration coefficients of the vertically sliding windows. Treats the criteria determining the rig design and the air flow measurement procedure. Treats tests on windows where the sealant did and did not appear defective, the overall values of window coefficients, testing of a weatherstripped window, the payback period for weatherstripping the windows.
Discusses the advantages of reducing air infiltration in industrial buildings in terms of energy conservation. States that heat loss due to infiltration is often underestimated or ignored as it is difficult to measure. Concentrates ondoorways as a major source of infiltration, and shows that the type of door used needs to match the requirements of the entrance, such as type and size of vehicle passing etc. Decribes a range of doors suitable for different conditions.
States that draughtproofing offers the shortest payback period of any form of energy conservation. Describes sources of draughts in industrial buildings, including entrance doors, and how heat losses through these can be minimized. Discusses recent developments in the domestic market which have encouraged weatherstripping. Briefly reviews different types of weatherstrip materials and how they should be applied.
Describes a national demonstration of the effectiveness of an optimal weatherization programme for low-income families conducted by the Community Services Administration and the National Bureau of Standards. 101 family dwellings in 12 cities
States that draughtproofing doors and windows in industrial and commercial buildings offers the quickest payback of any energy conservation measure. Describes potential sources of leaks, such as ill-fitting entrance doors, and the types of material needed in draughtproofing industrial buildings according to durability and application.
Gives answers to practical problems encountered when retrofitting older Canadian houses. The first section gives an overview of a typical house both before and after retrofitting. The second section gives detailed answers togeneral questions covering ventilation, moisture and condensation, air barriers (sealing a house), vapour barriers, insulation, basements, walls, attics, roofs, windows, doors, weatherstripping, caulking, air quality, heat recovery and heat loss testing.
Comments on the benefits of tighter house construction and gives a summary of the current tightness levels of the US housing stocks, based on a 300-house survey of infiltration measurements. Looks at 2 case studies of energy-efficient houses both for the details of their construction and for the air quality in the finished houses. Presents a set of drawing details that illustrate specific techniques for reducing infiltration. Includes methods of weatherstripping doors and windows, caulking and sealing, possible leakage points, and installing vapour barriers.
