Building energy storage system score

What is a Building Energy Asset Score?

The Building Energy Asset Score (Asset Score) is a national standardized tool for assessing the physical and structural energy efficiency of commercial and multifamily residential buildings, according to the U.S. Department of Energy.

Why do we need a standard protocol for energy storage?

Standard protocols are needed for testing and comparing TES systems to each other as well as comparing TES to other types of energy storage. Wide variation in building codes can be a barrier to new technology implementation. Codes and standards will need to be updated, or new ones developed, to capture TES.

Why is storage important in a building?

Storage sited at buildings can serve as important resources to promote grid reliability and flexibility, increase renewable penetration, and increase energy resilience. Current thermally driven loads make up more than 45% of the annual electrical energy consumed on-site in residential and commercial buildings (Figure 1).

Should building standards evolve to credit thermal storage?

Building standards may need to evolve to credit thermal storage. Rebates and other offerings can be used to encourage more decision makers to consider TES in buildings. It seems current consortiums are focused on electrical storage only. The TES industry should organize to present their case to regulators and policy makers.

What is the future of energy storage?

In addition to the U.S. government’s climate goals, the growth of electric vehicle usage, increased deployment of variable renewable generation, and declining costs of storage technologies are among other drivers of expected future growth of the energy storage market.

How much energy does a building use?

In the United States, buildings consume approximately 39% of all primary energy and 74% of all electricity. Thermal end uses (e.g., space conditioning, water heating, refrigeration) represent approximately 50% of building energy demand and is projected to increase in the years ahead.
