Next Steps in Defining Overheating- Discussion paper

This discussion paper suggests a framework for defining and assessing overheating risk in UK’s new homes. More specifically, the document draws on the evidence- based and expert views and advice of housebuilders, housing associations, local authorities, professional bodies, manufacturers, technical experts, academics and policy advisers to make preliminary recommendations relating to:

 

  • defining “overheating” in new dwellings being constructed; and
  • assessing the potential for those buildings overheating in the future.

 

Solutions to Overheating In Homes - Evidence Review

This report, released by the Zero Carbon Hub, reviews the range of technical and behavioural solutions available to reduce the risk of overheating in UK homes. The document covers a wide range of possible measures from town planning and building positioning, layout and orientation through to building fabric, windows, ventilation, to the actions of individual occupants. More specifically, more than 30 solutions have been considered and categorised according to whether they are based on:

 

Solutions to overheating in homes

This leaflet, released by the Zero Carbon Hub, highlights some of the many technical and behavioural solutions, which can be used to avoid or reduce overheating, without automatically resorting to energy-using cooling systems. It is based upon the ‘Solutions to Overheating in Homes’ Review, prepared by BRE for the Zero Carbon Hub as part of its large-scale project ‘Overheating in Homes’.

Defining overheating

This leaflet, released by the Zero Carbon Hub provides an introduction to the range of overheating definitions and thresholds in use in the housing sector and also by health professionals. It is based on work carried out by the Zero Carbon Hub over the past two years as part of a large-scale project on ‘Overheating in Homes’, and draws specifically the detailed evidence review, ‘Defining Overheating’.

Assessing overheating risk

This leaflet, released by the Zero Carbon Hub, introduces the variety of methods being used by housing providers and building professionals to assess risk, including Standard Assessment Procedure –SAP [UK Government’s procedure for rating the energy performance of homes and demonstrating compliance with Part L1A of the Building Regulations] Appendix P [SAP Appendix P provides an “overheating check”, which can be used to demonstrate compliance with Criterion 3 (covers overheating risk and requires ‘appropriate passive control measures to limit the effect of heat gains on indoor temperature i

Overheating risk mapping

This leaflet, released by the Zero Carbon Hub, introduces current research and risk mapping methods, including outcomes presented at a city or regional level, and a national level. It is based on work carried out by the Zero Carbon Hub over the past two years as part of a large-scale project on ‘Overheating in Homes’, and specifically draws on the detailed evidence review, ‘Overheating Risk Mapping’, prepared by AECOM for the Zero Carbon Hub.

Impacts of overheating in homes

This leaflet, released by the Zero Carbon Hub, is intended for housing providers and building professionals. The document highlights and summarises some of the key impacts of overheating in homes. It is based on work carried out by the Zero Carbon Hub over the past two years as part of a large-scale project on ‘Overheating in Homes’, and draws specifically on a detailed evidence review of the ‘Impacts of Overheating’ prepared by AECOM for the Zero Carbon Hub.

 

Strategies for mitigating the risk of overheating in current and future climate scenarios

Designing domestic buildings to perform well in terms of energy efficiency and comfort in both winter and summer, is important. During the summer well-insulated buildings are at risk of overheating (if not effectively shaded and ventilated), with this risk likely to increase with the effects of climate change. This article bring insights into the necessary measures to control overheating, by modelling different Passivhaus standard buildings over a range of future climate scenarios.
