States that the future belongs to light building structures which have been well insulated. A decided improvement may be achieved by windows, which must become an active element in the facade for air extraction. Air heating is considered. With ever decreasing heat resources, the division of heat flow mechanisms into basic inert and fast-control peak heating, is no longer an economical approach.
The Act (1981.592) on amendments in the Building Ordinance (1959:612) and implementing regulations appertaining thereto in the Building Code come into force on 1st January 1984. The regulations apply only to permanently used houses.
The problems associated with the measurement of ventilation rates and air movement patterns in large single cell buildings which were unoccupied and unheated were investigated using the tracer gases nitrous oxide and sulphur hexafluoride.
Wind pressures on three Navy buildings at the Kanehoe Marine Corp Air Station, Hawaii were measured. Indoor and outdoor variables were also measured including temperature, dry bulb, wet bulb, relative humidity, wind speed, and wind direction. Pressure measurements were carried out using Validyne DP103 pressure transducers, and a static pressure probe. Natural ventilation is estimated 1. by combining window areas and pressure coefficients with wind speed and 2. using the LBL infiltration model.
Describes expectations people have of indoor climate. Notes that the quality of indoor climate has often taken second place to fashionable architectural and material considerations. Refers to concern for improved environment and awareness of formaldehyde, radon and other pollutants and the need for correct ventilation to achieve derived air quality. Proves guidelines for air quality and the thermal indoor climate in both housing and working premises.
Illustrated booklet for the layman on heating and ventilation in housing which discusses the following: oil heating, wood firing, electrical heating, district heating, heat pumps, solar collectors for domestic hot water, ventilation systems, natural ventilation, mechanical ventilation, push-pull systems, heat exchangers, fans. Appendix discusses measurement of oil-fired system efficiency.
Surveys the Danish energy-saving program in the Ministry of Housing 1975-1987. Covers grant schemes, energy conserving measures in public and state buildings from 1975, control schemes for heating installations, and building regulations. Includes as an appendix a copy of the 1982 Act on the Reduction of Energy Consumption in Buildings.
Describes the major features of air flow around buildings, indicating how wind characteristics and building geometry interact to determine airflow round a house. Outlines work being done by Watson House in this area, mainly concerned with ventilation, flue performance and dispersal of combustion products.
The first part of the study describes thermography generally as a method for non-destructive testing of a building envelope for thermal and air tightness properties. The study has resulted in a two stage testing method of which pressurizing is an essential part. The field study has shown that thetwo-stage method is suitable in detection of air leakages, showing that the major part of thermal defects in the building envelope are due to air leakages.
