Cost Efficiency Guide

Jul 2016
The Guide begins by highlighting areas of cost risk when building a low energy home. It goes on to summarise the recommended actions across six stages of the house building process. Following the summary, further information is provided on each stage with 'keys to success' and 'pitfalls to avoid'.

Risk Management - Examples of Actions Being Taken by Housing Providers

Mar 2016
This slide pack is part of series produced by the Zero Carbon Hub for the Overheating Risk Management Project. The pack sets out examples of strategies and planned actions for managing overheating risk being taken by nine housing providers. It also covers common issues and barriers the case study organisation told us they face, some of which can only be resolved by national or local-level policies. See the "Guidance" section of the website for more information

Next Steps in Defining Overheating

Mar 2016
The Zero Carbon Hub has consulted with experts and professionals across the construction sector to produce a discussion paper which recommends a framework for defining and assessing overheating risk in new homes. This is an important development, potentially paving the way for a national standard on overheating.

Ventilation in New Homes

Mar 2016
The Zero Carbon Hub visited 33 dwellings across 6 construction sites in 2015 to see how effectively their mechanical ventilation systems were designed, installed, commissioned and handed over to occupants. This report presents the findings from the site visits anonymously. It is intended for organisations with an interest in quality assuring the delivery of ventilation systems, including government policy makers, developers and their advisers.

Solutions to Overheating In Homes Evidence Review

Mar 2016
This Evidence Review produced by BRE for the Zero Carbon Hub describes the range of technical and behavioural solutions available to reduce the risk of overheating in UK homes. The review 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. As such it covers issues relating to the local environment and neighbourhood as well as to the individual dwellings.

Technical Solutions to Overheating in Homes Leaflet

Mar 2016
This leaflet 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’

Overheating Risk Mapping Leaflet

Mar 2016
This leaflet 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.

Impacts of Overheating in Homes Leaflet

Mar 2016
This leaflet highlights and summarises some of the key impacts of overheating in homes for Housing Providers and Building 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 on a detailed evidence review of the ‘Impacts of Overheating’ prepared by AECOM for the Zero Carbon Hub.

Overheating in Homes - Drivers of Change Leaflet

Mar 2016
This leaflet, draws on the Thematic Evidence Reviews, commissioned by the Zero Carbon Hub as part of a large-scale project on ‘Overheating in Homes’, and sets out some of the patterns, statistics and projections relevant to the future extent of overheating. All projections carry a level of uncertainty and are sensitive to their underlying assumptions. As a result, any conclusions about future overheating based on these will also be uncertain

Defining Overheating Leaflet

Mar 2016
This leaflet 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’ authored by the Chartered Institution of Building Services Engineers (CIBSE), ARCC, University College London (UCL), and the London School of Hygiene and Tropical Medicine (LSHTM)

Assessing Overheating Risk Leaflet

Mar 2016
This leaflet introduces the variety of methods being used by Housing Providers and Building Professionals to assess risk, including SAP Appendix P, detailed dynamic thermal simulation modelling and the Passive House Planning Package. 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 ‘Tackling Overheating in Homes’, and specifically the detailed evidence review, ‘Assessing Overheating Risk’.

SAP Untangled

Mar 2016
SAP Untangled is aimed at the SME Builder and gives an overview of the Building Regulations Part L1A compliance process with respect to the SAP calculation. This Guide is intended as a basic introduction to the SAP assessment process and the information required by the assessor and Building Control in order to achieve compliance with certain aspects of Building Regulations Part L1A and the successful production of an Energy Performance Certificate for the home.

Services Guide

Mar 2016
This good practice guide aims to improve the standard of building services in new homes. The information is aimed at SME builders and their advisors, but there will be parts relevant to other building professionals. The scope is limited to focus on the major problems around design and installation of services that affect the comfort, indoor air quality and energy performance of new homes

Thermal Bridging Guide

Feb 2016
This document provides a simple guide to what thermal bridging is, the key construction details in new build housing where thermal bridging is particularly significant, examples of ways in which heat loss can be reduced by changes to the design and construction of these details, and the problem areas to avoid on site. It is intended to help designers and builders focus on the key decisions that they can affect around junction detailing which will have a direct bearing on the performance of the new homes they help to deliver.

Monitoring Overheating - Housing Association Case Studies

Aug 2015
The Zero Carbon Hub has been working with Government and industry partners over the last year to understand the extent of the issue of overheating in homes in England and Wales and what more Housing Providers, including housing associations, can do to mitigate this risk. This booklet summarises the experiences of four housing associations, with their kind permission. It discusses why they carried out monitoring projects, how they carried out the work, some of the results and importantly, how the results are being used within their organisations. Practical issues related to monitoring, highlighted by the case studies, are included in annexes at the end.

Local Authorities - Tackling Overheating in Homes

Jul 2015
For the last year the Zero Carbon Hub has been working with local authorities, central government departments and the housing and health sectors to understand how well prepared we are in England and Wales to tackle the issue of current and future overheating in homes. This booklet is intended to raise awareness of the issue and summarises some of the steps the local authorities interviewed by the Zero Carbon Hub are already taking to address overheating in homes in their area.

Builders Book

Jul 2015
The builders' book is a good craftsmanship guide that highlights key construction details when building a new home, and good practice for delivering them.The book aims to improve the quality of new homes built, especially with regards to comfort levels and energy bills. It helps builders improve site processes to deliver better performing homes and reduce the risk of condensation and mould growth, excessive heat loss and failure to meet building regulations.

Overheating in Homes: Executive Summary

Jun 2015
Why does overheating happen? How can the construction and energy efficiency sector prevent the issue getting worse? What can local and national governments do to support the housing sector? And why does it matter?
