Four Grid-interactive Efficient Buildings (GEB) solutions selected for evaluation in 2020.
Grid-interactive efficient buildings (GEBs) deliver cost savings by leveraging technologies and strategies that provide continuous demand management and load flexibility. GEBs comprise an optimized blend of energy efficiency, energy storage, distributed energy generation, and load-flexible control technologies. What makes them unique is their ability to optimize across these attributes over time (today such measures are individually optimized) while providing superior load flexibility. The GEB strategy results in a less peaky, more flexible energy load profile that unlocks new opportunities for efficiency, cost savings, and resilience.
Why is GSA Interested?
A recent Rocky Mountain Institute (RMI) report examined the benefits of a GEB strategy adopted across GSA’s entire portfolio. RMI identified five GEB capabilities with direct value for GSA:
- demand-charge management
- demand-response revenue
- GEB-specific rebates and incentives
- ability to access flexible time-of-use tariffs
- cost savings from enhanced energy efficiency
RMI also noted the added benefits for GSA of:
- better building control and occupant comfort
- reduced CO2 emissions
- deeper savings in energy savings performance contracts (ESPCs) and utility energy savings contracts (UESCs)
- continued Federal-government and real-estate-industry leadership
If implemented comprehensively throughout GSA’s portfolio, RMI estimates $50 million in annual cost savings, $206 million in net present value over eight years, and payback under four years.
How Will Success Be Measured?
Key performance indicators will be demand charge savings greater than 10% and payback under 5 years. Labor required to manage the technology will be tracked against increased operating efficiencies.
GSA Proving Ground (GPG), in association with the Department of Energy National Laboratories, is evaluating the real-world performance of multiple GEB solutions at four GSA test-bed locations. GEB solutions will be provided by Kinetic Buildings; Data Systems Analysts; Logical Buildings/Comcast MachineQ; and Prescriptive Data.
Adaptive Control for Chilled Water Plants [PDF - 186 KB] optimizes the operation of central plant cooling systems by using an adaptive control algorithm to achieve efficiencies across a building’s entire chilled water system, including chillers, air handling units, fan coils, and other distribution equipment.
Circuit-Level Energy Monitoring [PDF - 213 KB] analyzes energy use in real-time on a circuit-by-circuit basis. Compared to traditional submetering, the data delivered is more granular and installation promises to be less costly.
