ASHRAE Guide Highlighting Best Practices for Improving the Air Quality Indoors (IAQ)

ASHRAE published a free guidance document – A hugely valuable resource to help architects, engineers, FM’s and building managers obtain optimal air quality.

ASHRAE Guide Highlights Best Practices for Improving Indoor Air Quality With indoor air pollution now claiming 3.5 million lives worldwide each year, the need for maintaining healthy indoor air has never been greater.

To help educate architects, engineers, specifiers, contractors, and property managers on the proper techniques to maintain optimal air quality, ASHRAE – the American Society of Heating, Refrigerating and Air-Conditioning Engineers – is offering an important new publication free of charge.

ASHRAE’s Indoor Air Quality Guide: Best Practices for Design, Construction and Commissioning offers an array of guidance and resources for ensuring that indoor environments keep dangerous particles to a minimal and indoor air quality, or IAQ, at the highest possible level. To this end, the guide includes:

  • 40 strategies for achieving 8 critical IAQ objectives
  • Best practices for promoting optimal IAQ through design, construction, and building operation and maintenance.
  • In-depth information, organized by topic, to assist with implementing IAQ best practices.
  • Hundreds of links to resources to assist in the design, construction, and commissioning of buildings with optimal indoor air quality. Continue reading

Misconceptions about air pollution: ‘There’s nothing I can do about it’

Founder & Director of Clean Air London, Simon Birkett recently wrote an article for Environmental Health News on the Misconceptions about air pollution.

The piece contains a series of cartoons which the campaign group Clean Air in London commissioned to address the capital’s environmental challenges. Beautifully crafted by Andy Davey (@DaveyCartoons), the cartoons address matters such as London smog, wood burning, the tube, cycling and taxis.


What you can do:

Find out about air pollution near where you live, work and play. You can protect yourself by walking or cycling down quieter streets and reduce pollution for yourself and others by walking, cycling or using public transport rather than driving a diesel vehicle. Continue reading

Air Purification At Princess Alexandra Hospital Microbiology Laboratory

Camfil was asked to take readings of the levels of airborne particles in the microbiology laboratory facility which was located in a satellite building at princess Alexandra hospital – Harlow.

Alexander HospitalMany laboratory facilities in hospitals are situated in remote and detached locations to ensure more effective containment of contamination risk. These locations are often inadequately served by the centralised HVAC system.

There were concerns that there were contamination risks as hospital staff were being exposed to high levels of airborne particles and aerosols from medical pharma
compounds and possible exposure to airborne bioparticles.

The initial ambient air results did show that the concentration levels of airborne particles were higher than they should be because that the laboratory was being used to mix powdered medical preparations. There were also complaints about the frequent odours from liquid preparations and chemicals being used.

A CamCleaner unit was installed that had HEPA particle filtration and also gas molecular filtration for removal of noxious gases and odours. Continue reading
