Used for pipes and process equipment, the potential of mechanical insulation to play a significant role in reducing energy intensity is immense, but it is often specified incorrectly or, more frequently, not adequately maintained. A mechanical insulation energy appraisal was conducted on 25 facilities surrounding Helena, Montana to determine energy-, cost-, and emission-reduction opportunities available through repair, replacement, and maintenance of systems.

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. This article poses five questions that specifiers should ask about energy-efficiency data for VRF zoning and other HVAC systems, and provides the answers.
