Research and Guidance
The GHA runs a series of research and guidance projects, in partnership with leading academics, industry practitioners, and policy makers. Current and recent projects are listed below.
Phase 1, Fabric testing - Provision of technical support for GHA Developers in monitoring the fabric performance of their dwellings. Phase 1A covers 4 dwellings on 3 sites, all using different build systems (e.g. SIPS panels or thin joint masonry) and built to different standards, including Code 4, Code 5 and Ecohomes Excellent. Phase 1B has extended this monitoring to cover 4 further dwellings, including Code 4, Code 5 and Passivhaus schemes, and built using timber frame, Hemcrete and other systems.
Phase 2, In-use monitoring and post occupancy evaluation – Extension of the above monitoring on each site, to measure energy and water consumption, indoor air quality, humidity and thermal comfort, and occupant feedback.
Funded by Department of Communities and Local Government, Energy Saving Trust and NHBC Foundation. See the attached report for the Phase 1 results.
Ventilation and indoor air quality (VIAQ)
A project to identify good practice approaches to ventilation and low energy building design, that lead to good indoor air quality. The project gathered data from leading-edge projects that have recently been completed, covering whole house, mechanical extract, passive and natural ventilation solutions, and will examine common problems such as integrated design, installation, commissioning, and user behaviour.
Funded by the NHBC Foundation. See the attached report for initial findings.
The GHA is undertaking two pieces of work in this field:
1. An in depth study funded by the Technology Strategy Board into the potential for overheating in UK apartments, using the 'One Brighton' development as a case study.
2. An investigation, funded by DECC and the HCA, undertaken in partnership with the CIEH, into the scale of overheating in the UK, including common causes, and remediation techniques and costs.
