Describes air leakage tests performed in 2 similar houses (one with added insulation and increased airtightness) using the fan pressurization method. Air infiltration measurements were also conducted using the tracer gas decay method and CO2

Investigates the relationship between fuel consumption in a multi-storey block of flats and climatic exposure. Fuel consumption anomalies between identical flats are attributed to vagaries in the airflow around the building and highlight the need for improved standards of thermal insulation and/or differential thermal insulation, dependent upon flat insulation.

States that it is accepted practice to determine wind effects on and around a building by measurements in a scaled model in a boundary-layer wind tunnel. At large scales of reproduction it is impossible to simulate the entire depth of the atm

Reports on experiments carried out on models with trough roofs in order to study the influence of parapet height and wind turbulence. The models were exposed to both turbulent shear flow and a smooth uniform flow. Pressure coefficients were c

Reports on a study conducted to determine the impact of different ventilation rates on office building energy use, first cost, and peak electrical demand. Uses the DOE-2.1 computer program to simulate an energy-efficient office building in 5 cit

The heating system of a Junior High School in Minnesota has been re-equipped with a CO2-controlled variable ventilation system. The outdoor air dampers remain fully closed whenever the CO2 concentration is below a specified setpoint. During the early months of 1980, the system operated in alternate periods under the conventilanal temperature-driven control strategy and the experimental CO2-driven control strategy.

Describes the conditions of the "Heat Recovery from Exhaust Air" group of projects of the Swedish Council for Building Research. 

In future, high altitude correction factors will be considered in computing the ventilation heat load in high rise buildings. The algorithms necessary for the calculation are deducted and stated by the author.

Discusses air quality and the related definitions of ventilation efficiency. Suggests a definition of efficiency for ventilation systems in residential buildings that takes into consideration how ventilation air spreads within a dwelling. Measurements of the efficiency for exhaust, supply and combined systems show that for combined and supply systems the highest efficiency occurs in those parts where the air is supplied.

Outlines project where 25 representative dwellings from Birmingham Local Authority Housing stocks were monitored before and after energy retrofitting. Findings are presented as a set of case studies encompassing both fabric and infiltration measures. Suggests that simple energy conservation measures are successful but that more sophisticated combinations tend to under-achieve. Ventilation changes in several cases are impaired by increased use of windows and/or permanent ventilation. Where these effects are'nt operating, reductions of between 0.3 - 0.6 ac/hr appear typical.
