Important considerations for good building performance

Moisture movement, air-pressure and heat-flow continuously interact in every building. When working in harmony, these “building environment factors” positively influence the health of a building. When in discord, there are degrees of consequences.

Consequences of discord

  • Occupant illness
  • Building deterioration
  • Costly to operate
  • Uncomfortable
