LoginDescribes results from wind-tunnel tests on models of the Building Research Establishment's experimental building at Aylesbury.
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.
Gives a brief survey of aspects of research into air infiltration.
Looks at the requirements for computer model validation, especially in regard to predicting energy usage in buildings. Discusses the IEA project for comparing and validating several computer programs in this context.
Describes the relationship between wind flow round a building and heat loss from it.
States that the calculation of building energy flow is very complex, and so validation is a vital element in the development of any model.
Gives some conclusions from a detailed computer analysis of the energy consumption of 600 branch bank buildings of The Bank of Novia Scotia, spread across Canada. Divides energy management into 3 categories:
Reports on a study carried out by HUDAC and DBR on four identical detached houses built in Ontario in 1977.
Air leakage tests (using the fan pressurisation method) were conducted on four schools, before and after they were retrofitted, in order to determine the effectiveness of various measures for reducing leakage.
Reports the results of an experimental assessment of the effect of a chimney on the air leakage characteristic of an unoccupied two-storey detached house heated by either gas or electric furnace.
Describes the computerized instrumented residential audit (CIRA), a collection of building energy analysis programs designed for a wide variety of microcomputers. Covers methods and type of input, and types of output produced.
Describes "house doctoring", a combination energy audit and energy-saving retrofit procedure developed at LBL and Princeton University.
Improved insulation of domestic buildings has resulted in ventilation heat loss forming a large part of the total heat loss.
Traces the relationship between ventilation needs and methods and the growth of civilization. Describes the development of ventilation methods and assessment of air quality, especially since the Industrial Revolution.
Outlines ventilation needs to show that odour dilution and moisture control are the major winter factors.
Shows that efficient moisture removal in a ventilated roof via ventilation openings is a function of roof length. Beyond a certain critical length all moisture diffusing in from below will be deposited in the roof.
Describes a window opening survey concerned with identifying the objective correlates of window opening. Finds that the variation between households in terms of their total daily window opening is greater than that within households.
Detailed studies of public sector modernisation programmes show that the principal problem resulting from lack of thermal insulation and inappropriate methods of heating and ventilation is condensation and mould growth.
Gives a detailed description of 3 types of external shutters that were designed for 3 of 6 proto-type low energy houses at Hjortekaer Denmark.
Uses mathematical models for formaldehyde concentrations in 3 normal rooms in a single family house to estimate ventilation rates needed to maintain the formaldehyde concentration below the Danish recommended indoor standard (0.15 mg/m*3).
Distinguishes the problems of designing natural ventilation systems for summer and winter conditions and discusses in detail the objectives, methods and some field studies directed towards the solution of winter ventilation problems.< Describes
