The spectrum of commercial building efficiency technologies is large. Opportunities to save cost and energy diverge across market sectors, types, by systems and application, based on programming and occupant behavior and organizational mission. Fortunately, the Commercial Buildings Energy Consumption Survey (CBECS) provides a picture of energy consumption across these variables. Coupled with the energy efficiency measures captured in BTO’s Prioritization Tool (P-Tool), we have a running start. 

However, our analysis is only as good as our inputs. To inform this process, we gather information to evaluate and prioritize energy savings measures through our ongoing partnerships and collaborations as well as by conducting a thorough literature review (we call it the “Tech Sweep”) , soliciting new entries using the P-Tool Measure Input Form, and with an annual general Request for Information on High Impact Technologies (HITs).

The result of this data gathering exercise is a list of hundreds of energy efficiency measures which are incorporated into a matrix that ranks each measure based on quantitative evaluation criteria emphasizing national energy savings opportunity. Using the matrix, we pull out the highest ranked, market-ready measures and host discussion forums to uncover qualitative considerations such as cost, non-energy benefits, market conditions and other deployment drivers. 

Last year we hosted 10 fruitful discussions with 28 unique entities and 50 different individuals over two months. The outcomes of those discussions have helped us come up with our current HITs and make better strategic decisions about the HIT process and our deployment pathways moving forward. Some of the key takeaways from last year’s discussions were:

  • Remain aware of the need for technology groupings, applications and packages rather than specific technology types; address the synergies between technologies
  • Controls in general – across all load types – are an area where much work needs to be done. There are many competing platforms, protocols, etc. and many different ways to implement the control systems (individual fixture/load level, building level, etc.). End users are confused by the choices, afraid of technology obsolescence, and need guidance in this space.
  • Don’t always assume that a pure technology solution is the answer. In some cases, best practices or operational solutions can yield the same results at much lower costs.
  • Data on “real use” and end user behavior is extremely important in weighing the benefits of a technology, as the gap between “real use” and “ideal use” can be large.
  • There is value in enabling technologies such as smart metering, though it may be difficult to quantify independently.
  • Generally speaking, there can never be too much independent, third-party demonstration data.

This year we are hosting similar discussions to uncover emerging trends, technologies, and changing market drivers. Interested in participating?  Let us know: commercialbuildings@ee.doe.gov
