bba believes in research and development. Through participation in fundamental research we contribute to a better indoor environment and human health in the Netherlands and abroad. We share our expertise by supporting companies, governmental institutions and universities to increase and share knowledge. We are often asked to give a presentation, provide courses, write publications and take part in commissions. Moreover, we are co-authors of (international) standards and guidelines. Recently, we co-authored the Dutch Program of Requirements for Healthy Offices 2018. Using the publication, requirements for renovation or the construction of office buildings can be drawn beforehand, based on which designers, installers and contractors can make their plans.
