Goals

To reduce energy consumption and improve facility operations and maintenance.

Solution

Based on client feedback, we ultimately included five ECMs in scope and focused the major retrofit (GSHPs) on buildings that were deemed critical in the client’s long-term asset management plan. Including GSHPs to reduce fuel oil consumption as an ECM significantly reduced the site’s reliance on fossil fuels, increased energy security, and cut operating costs. In order to develop the GSHPs, we (1) performed calculations and design configurations to determine their required size and capacity based on HVAC loads, (2) surveyed the site to identify borefield locations, and (3) evaluated the existing central plant to determine required modifications.

Results

This project reduced total annual energy consumption by over 40% and water usage by 37%, helping the client reduce its operating expenses while enhancing energy resiliency. We developed a custom approach to Operations and Maintenance (O&M) and Repair and Replacement (R&R) for the GSHPs that accommodated the client’s performance period goals. Specifically, we assumed responsibility for preventative maintenance on specialized equipment (e.g., GSHPs) and provided O&M manuals, training, and oversight for the other ECMs, for which the existing O&M contractor continued to perform routine maintenance.
