Measured energy savings from residential retrofits: updated results from the BECA-B project.

Summarises measured data on energy savings from conservation retrofits in existing residential buildings, covering approximately 115 retrofit projects in four general catagories: utility-sponsored conservation programmes;low-income weatheriza

Measured ventilation and infiltration rates in eight US government office buildings.

Ventilation and infiltration rates were measured in eight office buildings using an automated tracer-gas measurement system. The buildings range in size from a two-story building with a floor area of about 2000 m2 to a 15-story office building.

Requirement-controlled ventilation of an auditorium.

Describe tests carried out in an 850-seat auditorium of 4000 m3 to compare the readings of a CO2 indicator for controlling the ventilation air flow with the readings from a Stafa odour indicator. Supplies the results in diagrams and tables and discusses them. Notes the odour indication agrees well with the CO2 indication until a certain point when the CO2 concentration is decreasing. Notes this need not be a drawback.

Measurements of ventilation rates and ventilation effectiveness

Describes how multizone tracer gas analysis techniques can provide a complete description of office ventilation. Treats the concept of ventilation effectiveness to characterise internal air distribution. Discusses the measurement of whole building ventilation rates and ventilation effectiveness in mechanically ventilated office buildings.

The Aylesbury experiment. Comparison of model and full-scale tests.

Describes experiments carried out by the Danish Maritime Institute using data from the Aylesbury experiments of the UK Building Research Establishment. The simulation of the standard rural terrain and the Aylesbury terrain was achieved by mea

Air quality control - measurements and experience.

Discusses use of a gas sensor developed on the Taguchi principle to measure air quality and control the volume of outside air introduced. Presents case studies of a concert hall and a lecture room, and calculates energy saving.

Condensation and damp.

Describes factors affecting condensation: moisture production, ventilation, heating, insulation, and absorbancy.

Metal industrial roofs moisture problems.

Discusses problems of condensation in cavity roofs of industrial buildings, including ventilation air as a moisture source. Lists points to watch when foam filling the cavity.

Wind environment around buildings.

General principles of air movement around buildings are stated, indicating where windy areas are likely to occur. Case studies are then described in detail, and lessons to be learnt from these are summarised. Descriptions of wind tunnel measurements around simple model buildings are followed by accounts of the use of meteorological wind data and of the effects of wind on people. A method of predicting wind conditions around a building is developed. Some notes on wind tunnel investigations are given.

Indoor air pollution due to emissions from unvented gas-fired space heaters.

Operation of an unvented combustion appliance indoors can elevate pollutant concentrations. Under laboratory conditions, oxygen consumption rates and pollutant emission rates of CO, CO2, NO, NO2, HCHO and submicron suspended particles emitted
