Audit Costs for the 1986 Texas Energy Cost Containment Program
Direct program costs for detailed audits of
13.5 million square feet of institutional building
space in the 1986 Texas Energy Cost Containment
Program were 0.050/SF. Large medical buildings (greater
than about 170,000 square feet) were audited for
0.0028/SF. The effect on audit costs of
complexity of recommended modifications, amount of
savings determined, amount of implementation
costs, building size, and building complexity are
discussed. Primary effects on audit costs are
size and complexity of buildings. Program
guidelines limited consideration of projects with
greater than a four year payback
LoanSTAR Energy Auditing: Update and Changes
Annual savings identified by detailed LoanSTAR audits during the period January, 1989 -December, 1991 are 46.1 million. These savings represent retrofit projects in state-owned buildings, local government-owned facilities, and independent school districts, accounting for 80%, 16%, and 4% of the investment cost, respectively. A summary of retrofit projects by type is presented and modifications to chillers and chilled water systems account for 26% of the savings and 32% of the cost, followed by lighting retrofits which account for 24% of the savings and 24% of the cost. The Governor's Energy Office has implemented changes to simplify the audit process by eliminating some calculations. Independent calculations and maintenance and operating procedures calculations are no longer required, and some retrofit projects may depend on standard paybacks to identify cost savings
Energy and Demand Savings from Implementation Costs in Industrial Facilities
The twenty-five most frequently suggested
energy saving assessment recommendations in the
Industrial Assessment Center program national
database were examined using linear regression
techniques to correlate between energy savings and
demand reduction, and implementation costs. Poor
overall correlations indicate that direct prediction of
savings from implementation costs is generally
unfeasible, with a limited number of exceptions.
Correlations for the twenty-five most frequently
suggested Texas A&M University recommendations
were better than those for the national dataset. The
value of this procedure to speed assessments seems
not worthwhile considering the poor correlations and
the value of the calculations it would replace
Texas LoanSTAR Monitoring and Analysis Program Progress Report
Eleven audit reports have been accepted by the review staff at Texas A&M
University. These eleven reports cover 3.8 million square feet of building space and two
street-lighting projects. One engineer has been employed to work in the GEMC for the
purpose of assigning audits, approving screening reports and reviewing overall auditing
progress
LoanSTAR After 11 Years: A Report on the Successes and Lessons Learned from the LoanSTAR Program
The Texas LoanSTAR program, which began in
1988, has produced over $110 million savings from
energy conservation projects applied to state and
local government buildings. One of the key features
of LoanSTAR has been the monitoring and
verification of the savings. Nationally, LoanSTAR
has served as a showcase for other states to follow.
LoanSTAR M&V methods have become the
foundation for the the USDOE's NEMVP, IPMVP
and ASHRAE's Guideline 14P.
However, underneath the success of the
LoanSTAR program are many lessons that have been
learned that are not as highly publicized. This paper
will present an overview of 11 years of measured
savings from the LoanSTAR program, including the
cost effectiveness of the LoanSTAR loans, trends in
LoanSTAR funding, lessons learned about how to
reduce the cost of a revolving loan program while
maintaining quality control, and a discussion of the
LoanSTAR emissions reductions
Program Overview: The Texas LoanSTAR Program; 1989-October 1999, A 10-Year Experience
The Texas LoanSTAR (Loans to Save Taxes
and Resources) program was conceived as a $98.6
million capital retrofit program for building energy
efficiency. The funding source is petroleum
violation escrow funds (PVE) from the Federal
government. LoanSTAR is administered by the
Texas State Energy Conservation Office of the
Comptroller's Office, under the guidance of Dub
Taylor, Director, and is the largest revolving loan
fund administered by a state for conservation
purposes. LoanSTAR was conceived in 1988 and
began in 1989. This paper summarizes the program
dollar savings and environmental impact from its
inception through October 1999

LoanSTAR Energy Conservation Audits: January 1989 - August 1990
Fourteen audit reports, covering seventy buildings
and Texas' Governor's mansion, have been accepted as a
part of the Texas LoanSTAR Program. Task 1 (the first of
five) is responsible for audit reviews and assignments. One
hundred forty-five energy cost reduction measures
(ECRMs) and maintenance and operation recommendations
(M&Os) have been identified which can result in
significant amounts of electrical energy, demand and
natural gas savings. Costs savings are 5,566,000 for an overall simple
payback of 3.0 years. The ECRMs and M&Os have been
categorized as well as the types of buildings involved. The
cost for auditing the 5.2 million square feet was $0.054 per
square foot. Problems associated with audit reports are
also discussed

Building Energy Use and Conservation in Cycle VIII of the Texas Institutional Conservation Program
Sixty-two technical assistance (energy audit)
reports by twelve different consulting firms representing
fifteen independent school districts, nine
hospitals, and five colleges have been reviewed to
assess energy use characteristics and recommended
energy saving measures. Such measures include both
maintenance and operation (H&O) measures (generally
regarded as "low-cost, no-cost") and energy conservation
(ECH) measures (generally more expensive and
requiring outside skills). Implementation cost,
annual savings of energy and costs, and paybacks
were reported for all M&Os and ECHs. Measures were
broken down by the consulting firms according to
energy use characteristics and categories, and it
was determined that average costs for electricity
and gas, before implementation of M&Os and ECHs,
were 4.85/MMBTU respectively. The
total implementation cost and projected annual
savings for the M&Os are 223,000
respectively, yielding a four-month payback. The
corresponding results for implementation of ECHs are
555,000, resulting in a four-year
payback. Also, some obvious problems in the preparation
of technical assistance reports along with
the general background and implementation of the
Institutional Conservation Program in Texas,
resulting from the National Energy Act of 1978, are
discussed
