Assessing Overheating Risk - Evidence Review

Mar 2015
This Evidence Review forms part of a wider evidence gathering exercise being conducted by the Zero Carbon Hub for our Tackling Overheating in Homes project. It provides a summary of relevant evidence and concepts on the theme: assessing overheating risk.

Defining Overheating - Evidence Review

Drivers of Change - Overheating In Homes

Mar 2015
This booklet forms part of a wider evidence gathering exercise being conducted by the Zero Carbon Hub for our Tackling Overheating in Homes project. It provides a summary of drivers of change relevant to future overheating in homes.

Overheating Study - Rowner Research Project Phase III

Feb 2015
The overheating study spanned from September 2012 to September 2013. This phase focused on the thermal behaviour of the properties during hot weather (summer months). Indoor thermal conditions were reviewed using CIBSE standards available at the time and compared to occupant perceptions of overheating. The results of this study will feed into the Zero Carbon Hub’s current national study: ‘Tackling Overheating in Homes’

Post Occupancy Evaluation - Rowner Research Phase II

Feb 2015
The post-occupancy evaluation phase spanned from September 2011 to September 2013. During this time information regarding actual energy and water consumption of the properties, the indoor conditions and the occupants’ experience of the properties were collected and reviewed. Differences in performance between the two blocks were also noted.

Closing the Gap Between Designed and As Built Performance - End of Term report

Jul 2014
This report draws together the findings of the Zero Carbon Hub project on Closing the Gap Between Design and As-Built Performance. It builds on two previous outputs; the Interim Progress Report (July 2013) and the Evidence Review Report (March 2014), together with subsequent work continuing the evidence gathering process and developing solutions to tackle various aspects of the Performance Gap. The appendices are available to view via links at the bottom of the Performance Gap section of the Current Projects page.

Zero Carbon Homes and Nearly Zero Energy Buildings

Apr 2014
This leaflet includes a summary of both the Zero Carbon Homes and Nearly Zero Energy Buildings (NZEB) definitions, with examples of NZEB energy targets from five European Members States.

Closing the Gap Between Design and As Built Performance - Evidence Review Report

Mar 2014
This report summarises the evidence gathering and assessment process undertaken between August 2013 and January 2014. It provides industry and government with a structured review of how and where the Performance Gap occurs within the current housebuilding process. This has involved a co-ordinated analysis of published literature and confidential industry research, and the development of a process review methodology to gather primary evidence from housebuilding delivery teams, including visits to live construction sites. The evidence collected so far has been used to prioritise which issues are considered to be the major contributors to the Performance Gap.1 The prioritisation process has been based upon the extent of evidence found and the significance each issue is considered to have on the Performance Gap.

Rowner Research Project - Factsheet 1 - Concept

Mar 2014
The research project at Rowner investigated the design and delivery of 24 apartments, split equally over two blocks. The developments were part of Phase I of a multi-phased project, the Rowner Renewal project. The first Block (B) was built to comply with the Code for Sustainable Homes (CSH) level 3 energy requirements, and Block C was built to achieve the Fabric Energy Efficiency Standard (FEES) This project provided the Hub with the opportunity to investigate the implementation of the FEES in built flats. The Project was funded by the Technology Strategy Board (TSB) as part of the Building Performance Evaluation programme (BPE), together with support from First Wessex, NHBC Foundation, LABC, Saint-Gobain, HCA and Taylor Wimpey. Additional Rowner Research Factsheets can be found in our Full Library.

Overheating and Ventilation in Homes

Mar 2014
This leaflet includes a summary of the work the Zero Carbon Hub is taking forward to help address the issue of overheating in homes.

Cost Analysis - Meeting the Zero Carbon Standard

Feb 2014
A long-standing goal of the Zero Carbon Hub is to work with experts across the house building sector to recommend energy and carbon standards for Zero Carbon new homes which are both stretching and cost-effective. For obvious reasons, understanding the costs associated with building Zero Carbon homes has been, and remains, a critical issue for stakeholders. It therefore continues to be a core part of the Hub’s programme of work. The analysis contained in this report, produced for the Hub by Sweett Group, provides an updated assessment of these costs. It reflects, for example, the significant reductions in installed solar PV costs seen in recent years. What the new analysis shows is that, in many of the scenarios considered, the cost of building to the proposed Zero Carbon Standard has roughly halved since we last published cost estimates in 2011. Furthermore, our projections suggest that costs may continue to fall between 2014 and 2020.
