3.   Hygiene, health and the environment 3.   Protection against adverse hygiene and health impacts related to construction works

The construction works must be designed and built in such a way that they will, throughout their life cycle, not be a threat to the hygiene or health and safety of workers, occupants or neighbours, nor have an exceedingly high impact, over their entire life cycle, on the environmental quality or on the climate during their construction, use and demolition, in particular as a result of any of the following:​ 

(a) the giving-off of toxic gas;​ 

(b) the emissions of dangerous substances, volatile organic compounds (VOC), greenhouse gases or dangerous particles into indoor or outdoor air;​ 

(c) the emission of dangerous radiation;​ 

(d) the release of dangerous substances into ground water, marine waters, surface waters or soil;​ 

(e) the release of dangerous substances into drinking water or substances which have an otherwise negative impact on drinking water;​ 

(f) faulty discharge of waste water, emission of flue gases or faulty disposal of solid or liquid waste;​ 

(g) dampness in parts of the construction works or on surfaces within the construction works. 

The construction works and any part of them shall be designed, constructed, used, maintained and deconstructed or demolished in such a way that they, throughout their life cycle, do not adversely affect the hygiene or health and safety of construction workers, occupants, visitors or neighbours as a result of any of the following:​

(b) the emission of hazardous radiation into the indoor environment;​ 

(c) the release of hazardous substances into drinking water or substances which have an otherwise negative impact on drinking water;​
