The evaluation included a nested program design to provide the highest level of certainty in the results; monitoring of the houses over a 45 day period through the use of on-site Campbell Scientific metering equipment; and remote polling of the on-site equipment through a modem. PEG's proprietary Model P was used for the peak effect determination.
The study concluded that APS has a variety of potentially worthwhile options to pursue for improving cooling efficiency and reducing peak demand. These options and their cost and impact were determined. and were outlined in the report.

After design of the new protocol, Proctor Engineering Group assisted Atlantic Electric to implement the new procedure by providing classroom and field training to program delivery personnel, including utility representatives, contractors and consultants.
As a result of Proctor Engineering Group's recommendations, Atlantic Electric restructured the Energy Smart Service Program to include the following:
Client: Arizona Public Service, Phoenix, AZ
Services: Develop and implement a pilot program to assess the potential energy savings and peak reduction from a new construction HVAC program.
Description:
This investigation involved field testing the air conditioning units, duct systems, and building shells of a sample of newly built houses; assessing achievable improvements to the systems; and analyzing the potential energy savings and peak demand reductions from such improvements. All of the above was normalized to APS' residential customer distribution across the climates of the service territory and to a typical meteorological year.

Services: Heat Pump Efficiency Protocols, Program Design and Training
Client: Atlantic Electric Company, Pleasantville, N.J.
Description:
Proctor Engineering Group provided review of current system protocols for Atlantic Electric's "Energy Smart Service Program" heat pump efficiency modification program. A combination of current protocols and on-site observation of the duct sealing and heat pump technicians was used to
design a program to meet the needs of Atlantic Electric.

Assessment of HVAC Installations in New Homes
The study concluded that improvements could be made to provide lower energy usage and reduced demand while improving occupant comfort and satisfaction. These improvements could be accomplished at moderate cost.
A second phase of this program is being conducted by PEG in 1995-6. This phase continues the work of phase 1 to validate and fine-tune the conclusions of the study. Thirty additional houses are being assessed.

The field study and sample collection methodology were developed by Michael Blasnik. The impact analysis included assessment of gas, electrical, and water usage in the RER houses. Conclusions of the study included estimates of the net costs of the specification changes and assessment of the resulting cost effectiveness. Average savings of the spec. changes was $247 vs. a net cost of $1311.

The impact evaluation involved a detailed examination of potential confounding factors due to problems with the treatment of comparison group selection processes and seasonal usage variations. Several approaches were used to provide reasonable, defensible program savings estimates and to attribute savings to individual measures.
Billing data analysis, OLS and robust regression modeling, and compared group treatment and comparison group demographics were used in the project. SAE models and graphical analysis methods were used to develop the savings estimates.

Proctor Engineering Group conducted each of the studies. The primary purpose of the comprehensive literature search was to help define and clarify the primary research questions and to summarize the results of previous Blower Door Guided Weatherization studies.
The Southern California Blower Door Breakpoint Study was conducted to determine the LIRA customer sample selection that the field study would target (Customers that represent a significant portion of the all-electric LIRA customer housing stock with sufficient heating or cooling use to make BGW potentially cost effective). The breakpoint study concluded that approximately 13% of Edison's all electric low income customers have sufficient heating and cooling use to consider BGW That target population was selected for a field test.
The field test was designed to compare pre-retrofit and post-retrofit energy usage of targeted customers that received BGW with a comparison group of similar LIRA customers. In the first stage of the test careful measurements were completed on twenty homes. These measurements indicated that only 10% of the sample had sufficient air and duct sealing potential to warrant application of blower door guided weatherization. Based on the applicability to such a small population (on the order of 1.3%), the remainder of the field testing was canceled.

Proctor Engineering Group acted as the technical advisor to the project team and has been actively involved in all phases of the project. In particular, PEG developed the training plan, implemented sections of the training, developed the analysis system which identifies measure viability, and provided regular oversight of the weatherization crew management. The analysis tool developed by PEG is based on billing information, targets specific measures to be installed and provides cost guidelines for the installation based on usage of gas and electricity.

Among the challenges in this study was the isolation of the effects of multiple cohorts and their separate consideration from year effects in the data. Michael Blasnik was responsible for developing a median polish technique which allowed the study to meet this challenge.
The final report was entitled "Looking Past the First Year: Do the Savings Last". The prime contractor was Wisconsin Energy Conservation Corp.
