RIBA Plan for Use Guide 2021

Plan for Use is the RIBA’s interpretation of the Soft Landings Framework produced by the Usable Buildings Trust and BSRIA. Its aim is to encourage a more outcome-based approach to briefing, design, construction, and handover, both within the architectural profession and (by extension) to the construction industry as a whole. The Plan for Use is embedded within the RIBA Plan of Work 2020.

The building performance evaluation guidance and toolkit, produced for Woodknowledge Wales on behalf of the Home-Grown Homes project has been referenced in the guide. The document was authored by Susie Diamond & Julie Godefroy, for the Good Homes Alliance.

Building Performance Evaluation Guide

This guidance is aimed at housing clients, and anyone interested in Building Performance Evaluation (BPE) who wants to evaluate and improve the performance of homes.

Its purpose is to provide an introduction to applying BPE in practice on projects, with:

  • Information for clients and project managers to gain an overview of the benefits of BPE, what the main BPE techniques can do, how to procure it, and the main activities to plan throughout a project from design to occupancy
  • Guidance on the main BPE techniques available
  • Tools for day-to-day use on projects, complemented by more detailed guidance, examples and references.

This guidance recommends a “core” BPE scope for clients and project teams wanting to understand and improve the performance of their homes. This provides a holistic look at performance, including people, the indoor environment, fabric performance, energy use and water use. It highlights how BPE techniques can work together, and the interactions between energy performance, people, and the indoor environment. It limits the involvement of experts and expensive equipment. Instead, the aim is to embed building performance throughout the project stages and empower project teams to deliver high performance.

State of the Nation: Domestic Buildings

There have been a number of studies undertaken over the last 10 years to understand the performance of homes, addressing issues such as energy consumption and outcomes for occupants and building owners. However, many of these studies are not widely publicised and limited to a small audience: their full potential is not being realised.

Now, we are transitioning into a new future of understanding building performance: the technology is becoming cheaper and data more available. As we enter a world of smart meters and smart homes, individuals and organisations will be better able to better understand how homes perform.

To harness the currently available knowledge and the opportunities around the corner, this work for the Building Performance Network addresses the following issues and includes:

  • A review of existing studies of domestic building performance.  Within scope are any studies considering energy consumption, thermal performance, environmental performance (including temperature, relative humidity and occupant feedback), and outcomes for occupants and housing providers;
  • A review of current building performance evaluation and assessment methods, including how these relate to energy consumption, comfort, health and well-being;
  • An assessment of how different building performance evaluation methods score against time, cost, and user expertise;
  • What smart meters and smart homes mean for the measurement of building performance;
  • The future of BPE, with recommendations for researchers, manufacturers, clients and where possible for the construction supply chain.

GHA Monitoring Programme

Phase 1

This report provides an overview of the findings, observations and recommendations resulting from Phase 1 of the Good Homes Alliance (GHA) monitoring programme. Phase 1 is based on post-construction testing of a series of new-build residential projects, across a range of construction types.

This project was funded by DCLG, EST and NHBC Foundation.

DOWNLOAD TECHNICAL REPORT 

Phase 2

This document focuses on the key results of the Phase 2 Post-Occupation Evaluation and compares the findings of the in-use performance data from the houses in terms of energy and water consumption and Indoor Air Quality (IAQ), the performance of installed building services, and occupant behaviour/ perceptions.

This project was funded by DCLG, EST and NHBC Foundation.

Case Study Report

Design for Future Climate – One Brighton

The scheme is part of a highly sustainable Masterplan for the regeneration of the New England Quarter adjacent to Brighton Rail Station. Completed in 2009 to BREEAM Excellent standard, One Brighton is an outstanding example of a contemporary urban, green apartment building. Sustainability was integrated throughout the design by following the ‘One Planet Living®’ model developed by BioRegional, together with WWF International.

This report considers a retrofit adaptation strategy to reduce the risk of overheating in a contemporary apartment block, One Brighton. The project is unique in the TSB Design for Future Climate Portfolio in two respects. Firstly, it is the only study, which is considering pure retrofit as opposed to new-build or more large-scale refurbishment of a building. Secondly, it builds upon the work of the TSB Building Performance Evaluation (BPE) Programme already undertaken for the development.

Case Study

Camden Passivhaus

Camden Passivhaus incorporates heat recovery ventilation, extremely good insulation and air-tightness, and high performance glazing to create comfortable and healthy conditions, and minimise energy requirements.

The project reported here is part of the Technology Strategy Board’s Building Performance Evaluation programme and acknowledgement is made of the financial support provided by that programme. Specific results and their interpretation remain the responsibility of the project team.

LowCarb4Real

Drawing on detailed academic studies at Stamford Brook along with GHA member experience, the GHA disseminated and implement this learning by providing education and technical support to GHA Developer members and others.

The LowCarb4Real project, funded through the UrbanBuzz programme (project No. 388), lies in the UrbanBuzz target area “Energy efficiency and sustainable housing: harnessing academic understanding”. As is recognised in the Urban Buzz programme, the contribution made to sustainable communities by reducing carbon emissions from housing is considerable.

Case studies

Information about how to achieve good performance on sustainable housing projects was then collected and a number of detailed case studies including:

Lincoln Grove, Bladon

Lincoln Grove is a development of 9 x 2 and 3 bed homes near Woodstock, 9 miles from Oxford, constructed in 2007. The homes were awarded EcoHomes excellent, scoring 77 credits, the same as BedZED. The homes have been subsequently re-assessed under the Code for Sustainable Homes and achieved level 3.
