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 as many as 600 lung cancers a year may be attributable to radon gas, and this may jump to as many as 1500 if energy conservation measures reducing draughts become more widespread. Notes that radon appears to be present in every hou

Describes large-scale field studies to investigate the effectiveness of measures to prevent condensation in some 4-storey blocks of walk-up flats in Stirling. The remedial measures in the blocks of flats are improvement of thermal insulation

Describes methods for measuring air flow rates and air velocities in buildings, with the aim of formulating identical rules within the Nordic countries for the inspection and adjustment of ventilation systems.

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

A model that relates fan pressurization results to infiltration values during the heating season is the basis for infiltration estimates in several different audit programs. Describes the model and presents validation results. Uses the model in 3 different audit strategies. The first is an energy audit to determine economically optimal retrofits for residential buildings, based on actual, on-site measurements of key indices of the house. Analyses measurements on a micro-processor and determines retrofit combinations compatible with minimum life-cycle cost and occupant preferences.

Shows the ventilation of electrowinning cell houses and electrorefineries as being a complex problem. Develops a systematic approach to define the important contaminant generation rates including heat, moisture and acid mist. Discusses fluid dynamic scale modelling as a powerful tool for solving a building's flow field and contaminant concentration field. Examines other associated problems, including wintertime fogging in the building and the high costs of make-up building heat. Presents the possibilities for reclaim of low-grade waste heat, and evaluates the economic impact.

Notes that many air conditioning and industrial installations function inefficiently since too little attention is paid to air movement in a room. Compares effect of inlet and exhaust air devices. Considers reduced ventilation need if pollution can be eliminated or reduced. States that ventilation efficiency is an indication of how efficiently the air is used in the occupation zone and that the air supply to a zone determines ventilation efficiency. Illustrates various forms of ventilation.

Indicates that 35-70% of a building's annual energy consumption is used by ventilation plant. Notes difficulty in determining which energy saving measures are most profitable but states that restricting fresh air supply tothat required is one measure that has not been considered and that most systems are designed for maximum capacity without facilities for varying load according to conditions. Describes plant which uses CO2-controlled ventilation in a sports hall. Illustrates circadian changes.

Discusses principle that the position of supply air devices has a considerable influence on the ventilation efficiency that can be achieved. Considers factors affecting ventilation efficiency and different ventilation models. Illustrates different air supply systems.
