Because there was no clear best strategy, the EPA’s guidance provided a framework and the basic requirements needed to demonstrate air quality improvements or emission reductions with adequate certainty to be incorporated into a State Implementation Plan (SIP) for achieving or maintaining National Ambient Air Quality Standards (NAAQS). The Energy Systems Laboratory, with guidance from both the US EPA and the Texas Commission on Environmental Quality (TCEQ), developed the first comprehensive engineering toolkit and database that satisfies the EPA guidelines. The value of this unique tool was demonstrated in 2005 when the Energy Systems Laboratory (ESL), at the request of the TCEQ, used it to develop integrated emissions estimates for all state agencies participating in the Texas Emissions Reduction Plan (TERP). Building on this expertise, the...

These areas face severe sanctions if attainment is not reached by 2009. Four additional areas in the state, involving 25 counties, are also approaching national

Senate Bill 5 was passed in the 77 th Texas Legislature in 2001. Although reducing NOx in mobile equipment (diesel) received the major emphasis, buildings also emerged as an important focus. Buildings consume approximately 21% of the energy used in Texas. Industry uses about 60% and mobile energy uses approximately 19% of the energy consumed in Texas. What caught legislative attention was that buildings consume approximately twothirds of the electric energy used, and that Btu reductions at the building site resulted in "two-for-one" savings at the generating plant. To address buildings, Texas adopted a building energy code and also set a procedure in place to encourage municipalities to improve on the code and obtain emission credits from the EPA.

Energy retrofit projects typically achieve projected savings. But in cases where savings goals are not being met, optimizing HVAC system performance can be the difference in an underachieving versus a successful project.

Rebuild America is coordinated at the national level by sponsorship through the Office of Energy Efficiency and Renewable Energy at the United States Department of Energy (USDOE). The Brazos Valley Energy Conservation Coalition (BVECC) has been a Rebuild America since 1996. Since 1996 BVECC has contacted 57 facilities in Texas about joining Rebuild America. Twenty-five of these facilities have authorized BVECC to conduct walk-through audits, and fourteen preliminary walkthrough audits have been performed. As of June 1999, nine facilities have joined the Rebuild America program covering a total of 8 million square feet of conditioned area. The total estimated project costs for retrofits at these 9 facilities are over $1 1 million, with annual savings of $2.6 million and an estimated 4.3 year payback. This paper presents an overview of the BVECC Rebuild America program in Texas, including a description of the program, conservation measures installed at the participating facilities, a description of the savings measurement methodology and a discussion of indoor environmental measurements.
