Ventilating dwellings in noise exposed areas
Developers must carefully consider the technical impacts of any planning requirements which preclude the use of openable windows in residential developments. The limited technical solutions currently available mean that any such requirements will severely constrain the ventilation strategy and have a direct impact on Part L1A CO2 compliance.

Thermal mass: more complex than it first seems
The effects of thermal mass on a building are not straightforward. The effects of high thermal mass can be positive or negative depending on the fabric specification of a building. The graph below illustrates the effects of thermal mass on a semi-detached dwelling, by showing the change Dwelling Emission Rate (DER, measured in kg CO2/m2/yr) [...]
SAP 2012 Consultation
A consultation on the Government’s Standard Assessment Procedure (SAP) for domestic energy use was released last week. Not yet available is the related and eagerly awaited CLG consultation on the Building Regulations Part L 2013. It is this second consultation that should contain details of the next big step-change in housing standards taking us towards [...]
Demonstrating compliance with Part L 2010
Is a good EPC rating a guarantee of good energy performance? Rightly or wrongly, there has been a concern that design criteria for energy efficiency, which are used by energy assessors as the basis for energy performance certification, have not always carried through to the final construction of projects. New requirements in force with the [...]
