BREEAM Indoor air quality plan

Contents

[edit] Aim and benefits

To recognise and encourage a healthy internal environment through the specification and installation of appropriate ventilation, equipment and finishes.

Poor indoor air quality is linked to health deterioration and therefore this issue seeks to minimise sources of pollution and optimise indoor air quality. There are many pollutants present inside our buildings and the materials we use to construct them. Of particular concern are volatile organic compounds (VOC) emissions and formaldehyde as these are known to cause cancer in animals. Indoor Air Quality Plans (IAQP) should therefore be produced to manage the contaminants within new buildings and will contain advice on the levels of contaminants that are acceptable, measures for specifying materials with low emission levels, detail procedures for flushing out buildings and advise on pre-completion testing to ensure acceptable levels have been met.

The IAQP should cover:
• Removal of contaminant sources;
• Dilution and control of contaminants during construction;
• Detail procedure for pre-occupancy flush out;
Specification for third party independent testing.


By specifying materials in accordance with the plan and flushing out the pollutants from the construction process sufficiently prior to building occupation, we can provide healthier work and living spaces reducing the potential for indoor air pollution and supporting the physical health of building occupants.

[edit] When to consider

Fully fitted buildings As early as possible. The objectives of the Plan are meant to be used in the Ventilation strategy. So it’s best to do prior to RIBA stage 2 to feed into HVAC design and complete prior to Detailed Design Stage (RIBA Stage 3 freeze) so that architects can implement into their specifications.

Pre-assessment -

Design Stage -

A copy of Indoor Air Quality Plan to be submitted as an evidence document

The Indoor Air quality Plan should be provided to the architect as typically it will list the standards that the finishes (usually specified by the architect) should comply with

[edit] Tips and best practice

Tips

  • Make sure it is someone’s responsibility to actually write this report.
  • This is a relatively low cost credit if you are struggling to find credits to boost you up to the next rating which aren’t already in the design.
  • Ensure that main contractor implements a policy of requesting the relevant certification for products (paints, varnishes finishes) during procurement.

Best Practice

  • If you wanted to go above and beyond BREEAM requirements, you could suggest making it mandatory for contractors to hand a copy of this guide (or an amended guide relating to maintaining air quality in use) to the occupants.

[edit] Typical evidence

Compliant Indoor Air Quality Plan - Typically you will receive a written report as an “Indoor Air Quality Plan”, however any form of evidence which complies with the BREEAM evidence principals would be acceptable for this purpose.

It may be helpful to provide clients with a template report, which contains each of the headings required. An example of this can be found in Tools and Resources.

[edit] Applicable Schemes

The guidelines collated in this ISD aim to support sustainable best practice in the topic described. This issue may apply in multiple BREEAM schemes covering different stages in the life of a building, different building types and different year versions. Some content may be generic but scheme nuances should also be taken into account. Refer to the comments below and related articles to this one to understand these nuances. See this document for further guidelines.
