The LTDA has agreed to commit resources to the campaign broadly equivalent to sponsorship monies rather than paying CAL.  The campaign is expected to include:

  • The LTDA making reasonable efforts to build public understanding of air pollution among its members and the general public.  This may include for example:
  • showing its support for ‘Clean Air in London’ on LTDA taxi receipts;
  • including information on LTDA receipts and other communication channels to build public understanding about air pollution;
  • promoting the free CityAir and/or London Air apps, which provide smog warnings and other information and advice, and the Clean Air in Cities app which reports the health impact on populations of long-term exposure to air pollution.
  • CAL writing two articles a year for ‘Taxi’ the official publication of the LTDA.

CAL and the LTDA are both concerned about the health impact of ‘invisible’ air pollution on Londoners – not least those exposed to the highest levels of air pollution on its roads – and want to see bold and early action.  CAL and the LTDA share many common aims including wanting:

  • more ranks for taxis;
  • rapid charging at ranks and specific stands which would allow taxis to be electrically charged within 30 or 40 minutes rather than eight hours;
  • more choice for taxi drivers in the vehicles they can buy;
  • sound transport policies backed by the real-world testing of vehicle emissions;
  • financial mechanisms to support drivers in purchasing new greener taxis e.g. structural funding and no VAT on purchases of ‘green’ taxis; and
  • smog warnings to protect people and reduce traffic when air pollution is at its worst.

In recognition of the above, the LTDA is becoming CAL’s first Bronze Sponsor.

In this issue we are making a landing in the world of molecular filtration – one of several clean air solutions offered by Camfil globally. We are highlighting molecular filtration in light of the growing awareness of poor indoor air quality, especially the presence of gas molecules and their impact on human health. The latest issue of AirMail includes: Continue reading

Improving IAQ protects health, enhances productivity and saves money

In office buildings, employees’ salaries account for 84% of building operation costs.  The financial benefits of improving indoor air quality (IAQ) in the workplace exceed building utility and maintenance costs. shutterstock_155609486office

5 facts on improving indoor air quality

  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

Outdoor air pollution infiltrates into buildings. Without appropriate ventilation, it accumulates and can even react with other indoor air pollutants.  Indoor air pollution is made of outdoor air pollutants, including heating and traffic particles and gases that infiltrate into our buildings.

Health impact of air pollution

Air pollution, both outdoors and indoors, impact on health results from acute or chronicle exposure.  It causes or aggravates eye, nose and throat irritation, headaches, respiratory diseases or asthma, impairs lung function and children lung development.  Recent research confirmed PM and O3 can cause cardiovascular diseases.  PM can cause lung cancer and impact endocrine system and brain function and development.  In fact WHO confirmed in 2013 diesel engines exhausts cause cancer.

EN13779 recommendations

To “keep the city out”, Camfil recommends products like its Hi-Flo™ series of filters high particle removal efficiency and air filters like City-Flo XL™, CityCarb™, City-Flo™ and CitySorb™ to maintain high IAQ in buildings situated along streets and roads with heavy traffic. “City” filters effectively control ozone and semi-volatile organic compounds (sVOCs), including PAHs (polycyclic aromatic hydrocarbons) from outdoor air and internal source pollutants outgassed by materials. In addition to their high energy-efficiency and ratings for removing sVOCs and ozone, City filters require no modifications to air handling units for installation.
