A 1: 20 scale model of a low-rise naturally ventilated building was tested in a wind tunnel. External pressure coefficients were determined for an open model with various combinations of ridge, sidewall and end wall openings, as well as for a sealed model. The pressure distribution is influenced by all structural modifications at various wind angles. The differences between the open and sealed models were pronounced especially at the ridge and the leeward sidewall.
An evaluation of the potential for energy savings in thermal distribution systems in residential and small commercial buildings has been carried out. Thermal distribution systems are the ductwork, piping, or other means used to transport heat or cooling effect from the equipment that produces the heat or cooling to the building spaces in which it is used. This evaluation was divided into four stages.
New Best Practice programme publications from the Energy Efficiency Office provide the building industry with guidance on construction design for well insulated new houses, writes Peter Barton-Wood, BRECSU
Inadequate controls - by today's standards - are estimated to cost industry and commerce £500 million a year in wasted ener9y. Terry Walters, chairman of the Building Controls Group of the Energy Systems Trade Association, looks at the opportunities in ventilation and air conditioning.
The environmental assessment of buildings is a potentially powerful means of reducing environmental impacts including those arising from energy consumption, writes Josephine Prior, Alan Yates and Paul Bartlett, Building Research Establishment
