Thermal bridging in energy efficient buildings

Posted on March 29th 2012

A thermal bridge is created where materials that are relatively poor insulators are in contact across an insulation barrier. This creates a low resistance path for heat to escape from in an otherwise well insulated construction.   Limiting thermal bridges is becoming increasingly important with higher environmental standards such as Code Level 4 and the impending 2013 Part L1a Building …

Shell and Core BREEAM for small commercial spaces

Posted on March 28th 2012

Many of our large residential schemes have relatively small commercial spaces which have to reach BREEAM standards for planning. We show below our recommended approach which should avoid any uncertainty: BREEAM New Construction Shell & Core Assessments are a less complex assessment specifically designed for later tenant fit out of commercial spaces. We recommend the use of this approach with …

Thermal mass: more complex than it first seems

Posted on March 16th 2012

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) for the dwelling modelled with …
