Flex Your Power Case Study: Elihu M Harris State Building

An Evidence-Based Practice

This practice has been Archived and is no longer maintained.

Description

Between June 2000 and 2001, the the Elihu Harris State Office Building in Oakland, CA implemented conservation improvements in lighting, heating, ventilating and air conditioning (HVAC) and plug-in loads. Elihu Harris’ chief engineer and engineering staff, with assistance from a Johnson Controls Service technician, gathered information on motor and lighting loads, utility bills and variable air volume (VAV) programming data through equipment surveys, fixture audits, building automation system (BAS) data and the utility website. The staff used the information to assess the feasibility, cost and return on investment of various energy projects. The Elihu Harris engineering staff, led by the chief engineer and assisted by the Johnson Controls Service technician, managed all energy conservation projects for the building.

Goal / Mission

The goal of this program was to improve the energy efficiency of the Elihu Harris State Office Building.

Results / Accomplishments

In June 2000, Elihu Harris’ total peak KW load was 1,416 KW (based on combined calculations of the average peaks for June/July/August season and the total load on the building during the time the building was closed – about 50 percent of each weekday). In June 2001, total peak KW load was 2,015 during normal operations and 1,300 during Stage 2 or 3 electrical emergencies. Between June 2000 and June 2001, Elihu Harris realized:
- 387 KW reductions in lighting, HVAC and plugin loads, or 13 percent.
- 346 KW in additional curtailments during Stage 2 and 3 electrical emergencies, or 12 percent.

An Evidence-Based Practice meets the following HCI criteria:

  1. The program description includes at a minimum: the sponsoring organization, program goals, program implementation steps, and outcomes that have demonstrated program success in achieving the program goal in one or more localities.
  2. The results from an evaluation of the program include quantitative measures showing improvement in the outcome(s) of interest after the implementation of the program (i.e. increase in smoking cessation, not just the delivery of a smoking cessation program). The outcome measure(s) is/are compared at relevant time periods before and after the intervention or program implementation. Alternatively, the evaluation study compares the outcome(s) between an intervention group and an appropriate control group.
  3. The study is of peer-review quality and presents numbers in a scientific manner; measurements of precision and reliability are included (e.g. confidence intervals, standard errors), results from statistical tests show a significant difference or change in the outcome measure(s), and relevant point estimates and p-values are presented. Note: if the results from an evaluation of a program are presented in a scientific manner and the outcome measure is improved compared to the baseline measurement or the control group but the difference is not statistically significant, the practice is classified as effective and not evidence-based.
