Rooftop Units and Controls
Energy Trust offers incentives for the installation of new rooftop units with manufacturer-installed advanced controls in multifamily buildings. These packaged units have all the components for heating and cooling in one place, making them easier to install and service. Plus, their placement on the roof maximizes indoor square footage for tenants.
Advanced Rooftop Controls (ARC) reduce fan speed during heating and cooling and can help building owners and operators can save money while making their buildings more comfortable.
