Liberty’s assessment of High-performance buildings: Are buildings getting better or are lawyers getting richer?
When you increase the influence of a particular driver in a building you increase the risk of failure. High-performance buildings increase drivers for both HVAC systems and Building Envelopes and this means more risk of failure for designers, contractors, and owners.
Liberty has found these drivers that will influence future risks for moisture control in buildings:
More energy efficiency compromises dehumidification
Energy recovery techniques increase risk of building pressure problems
Increased thermal efficiency increase the likelihood of condensation
Increased complexity of the envelope increases risk of water intrusion entry points
Increased use of new products means your next project is an experiment in the making
