This paper presents an account, and results, from the U.S. Gas Industry's on-going program to assess the effectiveness of various retrofit actions to increase the seasonal efficiency of central, gas-fired, space heating, residential furnac
A large number of developments are under way in the United States of America aimed at providing new high efficiency, space heating equipment for existing and for new single and two family dwellings. The majority of these developments are s
Describes construction of two townhouses taking into consideration several technical issues: 1) limiting of indoor sources of contamination, 2) limiting contaminants off-gassed from construction materials, 3) limiting entry of exterior contaminants, 4) control of occupant generated contaminants by mechanical and by natural ventilation, and 5) control of indoor humidity The units are to be monitored over the next two years.
The primary objective of this paper is to show the distribution of heat losses in prairie commercial greenhouses of various constructions and to suggest and test methods of energy saving. Seventy five percent of the total heat loss is through the roof of a glass greenhouse. This can be significantly reduced by adding an extra layer of polyethylene preferably in the area where lower lightlevels can be tolerated.
Efforts to reduce the energy needs to heat or cool dwellings have the potential to create new health hazards. Increases in indoor levels of radon and its progeny from the reduction in air exchange rates add a substantial radioactive burden to the general population. Other indoor pollutants reaching critical concentrations in homes with low air exchange rates are CO and NO2 from unvented combustion in gas stoves and heaters, tobacco smoke, and asbestos fibres.
Measured energy consumption figures are presented for a townhouse complex located in Regina, Saskatchewan. The complex consists of 8 two-storey wood frame structures incorporating low energy design principles and some passive solar features.
The Linford project involved designing, building and monitoring 8 low energy passive solar houses. The houses were insulated to current Danish Regulation standards. Seven occupied and 1 unoccupied test house were monitored over two years.
The Linford project involved the design, construction and monitoring of 8 low energy houses in Milton Keynes. The houses were insulated to current Danish Regulation standards and incorporated several passive solar features. Seven occupied and
Examines providing some existing multifamily houses with mechanical ventilation with heat exchanger by installing new inlet air ducts to bring back the heat contents of the outlet air.
The heat losses from small houses, due to transmission and ventilation, are estimated. The estimation i s based up on the house owness daily readings of electricity and water meters, and their notes on behaviour influencing the energy use. Consideration is taken to heat supply from insolation and from people. Hot water losses are calculated from use of water and use of household machinery. Besides the estimation of the heat losses, Q, wind and temperature in the area is registrated .
