This project applied energy-saving measures in three trade-specific disciplines (mechanical, lighting, and plumbing) to existing buildings
HVAC systems at three buildings, totaling approximately 500K + sq. ft. were modified from constant volume systems to variable air systems. These three buildings were primarily laboratory and research buildings with high but inconsistent exhaust needs. The application of variable air systems included modifying existing motors, using VFD controls, and adding VAV boxes. To determine baseline energy savings, a careful examination ad verification of existing infrastructure air systems was performed prior to design.
Lighting fixtures at six buildings, totaling approximately 1M+ sq. ft., were modified from fluorescent to LED lamping sources. To reduce material costs, existing fixtures were retrofitted with new energy-efficient LED lamping. In addition to calculating light levels to determine baseline conditions, the existing infrastructure was documented. Motion sensor monitoring was deployed to study the cost payback of the occupancy sensor application.
Plumbing fixtures at six buildings, totaling approximately 1M+ sq. ft. were replaced with flow water-efficient models. Existing and proposed water usage was calculated to determine domestic water heating and conservation values.
