Safety Warning – Cord Operated Equipment: NEW added 01-12-20 (26Kb)

Safety Warning – Cord Operated Equipment. In the absence of clear specific legislation for ventilation systems RVA have produced a guide on this safety related issue.

Domestic MVHR systems – (0.5 MB)

MVHR systems in homes – post-installation performance perception and reality. This paper summarises the combined experiences of our members on how systems perform post-installation and compares the maintenance of such systems with conventional ventilation systems for consideration alongside other opinions on these matters.

CPD for Domestic Ventilation – Presentation: added 06-11-08 (2.6MB)

The Building Research Establishment (BRE) has produced several useful publications on the application of ventilation in households and non domestic buildings.

All of these are available from the BRE at but some of the most useful ones are listed here, with a brief description.

IP 13/94 Passive stack ventilation systems: design and installation by R K Stephen, L M Parkins, M Woolliscroft; 1994

Passive stack ventilation is a means of removing unwanted moisture from dwellings. The proper design and installation of these systems is vital to their successful performance. This paper gives detailed guidance on this subject and is in support of the 1995 edition of the Approved Document to Part F of the Building Regulations.

IP 12/00 Positive input ventilation in dwellings by R K Stephen; 2000 Positive input ventilation is the usual name for systems in which fresh air is supplied to a dwelling from the roof space by means of a fan. It was originally developed in the 1970s to deal with condensation in dwellings without adversely affecting the operation of open-flued combustion appliances. While there is considerable anecdotal evidence that the installation of these units can improve indoor humidity conditions, measurements of performance have been few. This paper gives a summary of the results from performance measurements made in a BRE test house and in 15 occupied dwellings. It will be of particular interest to dwelling designers, landlords and domestic property managers.

BRE Digest 398 BRE digest 398 Continuous mechanical ventilation in dwellings: design, installation and operation (Photocopy) 1994

This Digest deals with ducted extract systems and balanced supply and extract systems, with and without heat recovery. It considers the characteristics of dwellings and their heating systems, and the design, controls, fire precautions, installation, cleaning and maintenance of such systems.

The Housing Energy Efficiency Best Practice Programme (HEEBPp) helps people to introduce energy efficiency measures in homes to the highest standards.

Energy efficiency helps:

  • reduce your clients' fuel bills
  • tackle climate change
  • reduce fuel poverty

The HEEBPp programme of activities consists principally of publications and events. Guidance is given on reaching the best possible standards in energy efficiency.

GPG 268 Energy efficient ventilation in dwellings (2006)

Published by the Energy Saving Trust in 2006, the guide explains why ventilation is important, the impact that good ventilation has on achieving the efficient use of energy, and the importance of air-tightness. It also describes the advantages and disadvantages of a range of ventilation systems. The guidance is presented in two parts:

  • General issues and theory relating to ventilation.
  • Ventilation options

General Information Leaflet 72 from the best Practice Programme

GIL 72 Energy Efficiency Standards – For new and existing dwellings. The aim of this leaflet is to provide Specifiers, Installers and Purchasers with a set of Energy Efficiency Standards that can be used in the design, construction and refurbishment of dwellings in the UK. This leaflet sets out the reasons why we need them, explains what they are and discusses the potential implications of their application.

GPG155 Energy Efficient Refurbishment of Existing Housing: 2003

This Guide provides advice to help landlords, private developers and others to refurbish and repair their existing housing in an energy-efficient way. It provides practical advice on the full refurbishment of dwellings as well as individual improvement measures during repair. The Guide answers the questions: How energy-efficient? What is cost-effective? How can I avoid problems? What are the best options to use? Where do I go for more information? This publication is based on experience gathered over many years and this edition updates the earlier (1995, and 2001) versions.

Updated 2003 in line with HEEBPp standards and changes to building regulations in England & Wales, and Scotland.

Building Regulations

Building Regulations ensure the health and safety of people in and around buildings by providing functional requirements for building design and construction. In addition, the Regulations promote energy efficiency in buildings and contribute to meeting the needs of disabled people.

The UK Approved documents are available from

The most important for ventilation are:

Approved Document F - Ventilation (2006 Edition)

Approved Document L1 - Conservation of fuel and power in dwellings (2006 Edition)

Approved Document L2 - Conservation of fuel and power in buildings other than dwellings (2006 Edition)

In Scotland the Building Standards Division (BSD) has been re-integrated into the Scottish Government and has become part of a new directorate for the Built Environment which includes Planning and Architectural Policy. The Building Standards Division (BSD) is responsible for writing the Scottish building regulations or Technical Handbooks.

Section 3 of the Domestic Handbook is on ventilation

British Standards

BSI ( produce many standards – some of the most relevant are:

  • BS 5250:2002 Code of practice for control of condensation in buildings
  • BS 5925:1991 Code of practice for ventilation principles and designing for natural ventilation
  • BS 5720:1979 Code of practice for mechanical ventilation and air conditioning in buildings
