*TITLE:* Commercial Building Energy Saver: An Energy Retrofit Analysis
Toolkit

*SPEAKER(S):* Mary Ann Piette, Tianzhen Hong, Yixing Chen, et al.

*LOCATION:* LBNL Bldg. 90, room 3122 (in Berkeley, California)

*DATE & TIME:* At 12:00pm, Thursday, July 2, 2015

*DESCRIPTION: *Small commercial buildings in the United States consume 47%
of the total primary energy of the buildings sector. However retrofitting
these buildings poses a huge challenge for small and medium-sized
enterprises as building owners usually lack the expertise and resources to
conduct on-site energy audit to identify and evaluate cost-effective energy
retrofit technologies. This seminar presents the Commercial Building Energy
Saver (CBES), an energy retrofit analysis toolkit, which calculates the
energy use of a building, identifies and evaluates retrofit measures in
terms of energy savings, energy cost savings and payback. The toolkit
provides a rich set of features as follows: (1) Energy Benchmarking
provides an ENERGY STAR score for the building and how it compares with
other peer buildings in California; (2) Load Shape Analysis identifies
potential building operation improvements using statistical analysis of the
building?s 15-minute interval electricity use data; (3) Preliminary
Retrofit Analysis searches a pre-simulated database for retrofit measures
based on investment criteria; and (4) the Detailed Retrofit Analysis
performs EnergyPlus simulations to evaluate energy savings of user
configurable energy conservation measures considering the actual building
characteristics and operation schedules. The CBES Toolkit includes a web
app (cbes.lbl.gov) for end users and the CBES Application Programming
Interface for integrating CBES with other energy software tools. The object
oriented software architecture of CBES enables its expansion to cover more
building types, more climates, and more building technologies in future.
