||This work has been carried out to help develop guidance on siting open flue terminals for natural draught domestic gas boilers. The effects of adjacent structures and topographical features on wind pressure fields around dwellings were investigated, and scenarios with high likelihood of flue flow reversal were identified. A combination of wind tunnel testing and computational modelling has been used. Vent pressures on isolated dwellings have also been investigated. Compared to isolated dwellings, the maximum pressure experienced by a flue terminal above a 45░ pitch roof was found to be up to 60% higher when very tall or wide structures (e.g. embankments) were located downwind of the dwelling. The percentage increase was higher for the 30░ pitch roof, although absolute pressures for the 45░ pitch roof were greater.
