How improving indoor air quality can protect health, improve productivity and save money

Why is improving Indoor air quality so important?

  1. Better IAQ increases productivity in offices by 10% thanks to higher air supply rate and appropriate filter maintenance.
  2. Polaroid managed to reduce sick leave by 35% and save 400$ per employee by upgrading buildings HVAC Systems, equalling close to 1,5Million $ total savings per year.
  3. According to an Australian study, improving IAQ reduces sick leave rate by 39% and costs by 44%.
  4. Better IAQ improves schoolchildren reading test results by 13%
  5. Improving by 1% productivity with better ventilation system can save between 20 to 60€/m2, with benefit to cost ratio of 9.4 (productivity/HVAC investment, Energy and maintenance cost). Payback time was less than 2 years.

How to improve IAQ ?

1. Indoor pollutants source emission control

2. Appropriate ventilation system design and improvement

3. Air filter selection at air inlets according to EN13779

4. Additional molecular filtration or air cleaning for specific locations and pollutions Continue reading

How to improve your indoor air quality – Understand IAQ standard EN13779

Buildings may have mechanical ventilation, air conditioning and/or air filtration or none of these and few buildings comply with indoor air quality standard EN:13779.

A report by Campaign for Clean Air in London (CAL) highlighted the lack of understanding among senior managers and others that few buildings comply with indoor air quality standard EN: 13779.  

In London for example many Local Authorities do not know if their buildings comply and many Local Authorities do not know about compliance in their schools and that significant opportunity exists to improve indoor air quality and reduce energy costs.

So what can I do? Continue reading

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
