Jacobs, P. (author), Voogt, M.H. (author)People are more than 80% of their time indoors. However, in contrast to ambient air, no (legal) limits for indoor particulate matter exist. This paper describes a measurement protocol to determine the yearly averaged indoor PM2,5 concentration and gives reference values for five quality classes: <2,5 μg/m3 (A+), <10 μg/m3 (A: WHO annual advisory...conference paper 2015

Jacobs, P. (author), Voogt, M.H. (author)TNO heeft begin dit jaar samen met de VLA een meetprotocol voor de bepaling van fijnstof (PM2.5) ontwikkeld. Het protocol beschrijft hoe met optische deeltjestellers op basis van een week meten een schatting voor de jaargemiddelde fijnstofconcentratie in kantoorruimten kan worden gemaakt. Met de uitkomsten van zo'n meting is de afweging...article 2014

Jacobs, P. (author), Phaff, J.C. (author), Voogt, M.H. (author)An intervention study with a decentral electrostatic filter has been carried out in a nursery. The field study shows that it is possible to reach a reduction up to 80% of ultra-fine (<0.1 μm) and up to 68% for the PM1 and PM2,5-PM1 fractions at a relatively low energy consumption. These particle fractions were mostly determined by the outdoor...conference paper 2014
