LoginStates 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.
Bibliographic database Airbase
AIRBASE is the Bibliographic Database of the AIVC. It contains publications and abstracts of articles related to energy efficient ventilation. Where possible, sufficient detail is supplied in the bibliographic details for users to trace and order the material via their own libraries. Topics include: ventilation strategies, design and retrofit methods, calculation techniques, standards and regulations, measurement methods, indoor air quality and energy implications etc. Entries are based on articles and reports published in journals, internal publications and research reports, produced both by university departments and by building research institutions throughout the world. AIRBASE has grown and evolved over many years (1979 to present day, over 22000 references and 16000 documents available online). For most of the references, the full document is also available online.
Access to the publications is free of charge.
Presents the contents of a memorandum of evidence to the Royal Commission of Environmental Pollution.
Data on energy use was compiled for 223 retrofitted US commercial buildings and analysed for average savings, average retrofit costs, correlation between cost and savings, type of retrofit attempted etc.
BECA-B assesses the technical performance and economics of energy conservation retrofit measures. The data collected represents measured energy savings and retrofit costs for over 65 North American residential retrofit projects.
Residential air-to-air heat exchangers - Performance, energy savings and economics. | 1983 | English
Residential energy consumption can be decreased if air infiltration is reduced. However, reduced air infiltration can lead to problems with indoor air quality (eg excess humidity and high levels of indoor-generated air contaminants.). One sol
Sets out the results of research into ventilation and radioactive radiation in 20 private dwellings. All the houses had radon daughter contents in excess of 800 Bq/m3.
Development of the air infiltration model for the energy performance design system. | 1983 | English
Describes the Energy Performance Design System (EPDS) which is a simplified procedure for energy analysis based on extensive field testing, laboratory experiments and computer modelling.
Uses a validated multi-cell mathematical model of air infiltration to analyse the influence of various ventilation strategies on air distribution and energy demands.
89 male and female judges have evaluated the intensity and acceptance of body odour when they enter 2 experimental auditoria occupied by 41-216 men. More than 1000 men served as occupants during 200 experiments.
A procedure for field surveys of indoor air quality in energy efficient residences. | 1983 | English
Describes a field method for surveying residences for indoor air quality.
Uses social survey data to test the hypothesis that residential energy conservation measures have the effect of reducing air quality in the home and have a subsequent deleterious effect on the health of the residents.
Develops and tests a low-cost computer-assisted diagnostic package to supply the architect and engineer with key information and understanding of the energy use, balance and resulting saving potential of existing and new buildings.
Reviews new standards on thermal comfort and discusses the scientific basis for some of the limits. Presents new data for human response to asymmetric radiation and air velocity.
Undertakes experimental studies to identify antecedent conditions of various health and comfort problems experienced by office workers in sealed, air conditioned buildings in New York City and Vancouver.
Compares LBL infiltration model predictions with air infiltration and weather data collected by MITU. Examines 4 simplifying assumptions in the model:1. The flow through cracks in the building shell can be approximated by orifice flow 2.
Writes for experts and non-experts on calculation methods for energy consumption in buildings. Gives a brief introduction to the physical and numerical bases used in this field.
Describes some new theoretical and experimental techniques developed by British Gas to investigate the ventilation of buildings. These include:< 1. The multi-cell model "vent" for predicting ventilation rates< 2.
States that in a tight house with a vapour barrier, an air management system is needed to provide fresh air and remove the build-up of moisture generated by the occupants.
The Fanger Comfort Equation is coupled to a building simulation model. Discusses some factors related to thermal comfort. Incorporates variables influencing comfort as subroutines in the main thermal analysis program.
Evaluates the intensity and acceptance of body odour as perceived by 89 male and female judges entering 2 auditoria occupied by 50-200 men. Performs 200 experiments with varied ventilation rate, space volume per occupant and temperature.
