Part L 2013 – The Increased Importance of Thermal Bridging

Posted on January 16th 2014

  SUMMARY Achieving compliance with Part L1A 2013 will require detailed consideration of thermal bridging in all new dwellings. For some dwelling types, this is already common practice.  For non-traditional construction types where developers have typically used default values for thermal bridging, design teams have a choice of either making significant improvements to all other fabric values, or carrying out …

The Increasing Importance of Thermal Bridging

Posted on September 23rd 2013

Thermal modelling of construction details is a key tool for developers seeking to comply with the new fabric standards for Part L 2013 and address the technical concern of surface condensation risk. This will become increasingly valuable when statutory fabric performance requirements are introduced in April 2014. Using 2D and 3D thermal modelling software, we are able to assess construction …

Ventilating dwellings in noise exposed areas

Posted on May 6th 2013

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. Where planning requirements for developments in areas with significant noise exposure preclude …
