The ability to detect trapped moisture within a wall system is useful in evaluating the condition of an exterior wall system, and critical for evaluating sheathing durability. Finding hidden water using non-destructive techniques such as infrared imaging can be useful if the techniques are used correctly.

As in HVAC systems, variable refrigerant flow (VRF) zoning technology is increasingly specified for its superior energy-saving benefits and precise zoned control. Nevertheless, specifiers often find it challenging to compare the energy-efficiency data of traditional commercial HVAC with VRF zoning systems.
