Yianni Spanos on what the recent revision to Part F of the Building Regulations will mean for the construction industry… 

One of the challenges for achieving low energy buildings is to significantly improve their air tightness. Ventilation provisions within the new Building Regulations Part F have been increased for commercial buildings and dwellings with a recommended design air permeability tighter or equal to 5 m3/(h.m2) @50Pa.

Focusing on construction, achieving an air tightness target of 5 m3/(h.m2) is not a difficult task. For many years specifiers have demanded significantly better standards of air tightness in quality buildings to ensure that the occupants enjoy a satisfactory state of comfort and well-being. For air-conditioned buildings, and buildings which aim to be low energy, a maximum air permeability standard of 3 m3/(h.m2) has been set by many building owners and operators.
