“…An advantage to this method is that once the data are collected, they are in a format consistent with other data collected by the logger. Two such techniques were used by the monitoring contractors and sponsors in the Energy Edge monitoring project (see Piette et al 1994), where the dedicated datalogger tapped directly into some of the EMCS sensors, and also tapped into the EMCS communication network to collect EMCS data.…”

“…In this program, state-owned buildings receive loans to install energy retrofits, and monitoring is used to determine what the savings are. Another example of monitoring in evaluation programs is the Energy Edge evaluation (Gardner andLambert 1987, andPiette et al 1994). savings verification: closely related to evaluation of savings is verification of savings.…”

“…By using monitored whole-building or end-use data, or operational data, to check the results of the simulation, the inputs can be adjusted until the output matches the measured data, and then the calibrated model can be used to carry out other types of "what-if" analysis. A prime example of this is the Energy Edge evaluation (Piette et al 1994). Ternpermre correlation: Simple correlations of whole-building or end-use energy consumption with outdoor climate indicators can be useful in estimating savings.…”

“…The budget for these programs, per site, is usually higher than would be possible in a larger project. An example of the use of monitoring in a case study program is the evaluation of the Energy Edge design assistance program in the Pacific Northwest (Piette et al 1994). In this program, 28 buildings were being monitored to determine how much less they used than they would have used if they had been built without design assistance.…”

“…PacifiCorp developed their commissioning program as a result of direct experience with the energy performance of energy-efficiency improvements in new commercial buildings. The util' rty worked with the Bonneville Power Administration to administer a researchdented new commercial construction and demonstration project @led Energy -Edge (Yoder and Kaplan, 1992, Piette et al, 1994). Energy Edge was perhaps the most detailed evaluation of EEMs in new Commercial buildings ever conducted.…”

IV V assume that once commissioned, the EEM saved 100 percent of the design estimate, plus additional savings from correcting deficiencies that were not related to the EEMs. Under these assumptions the average and median simple payback times are 9.6 and 9.9 years. These results a r e dominated by the economics of the EEMs. The economics are sensitive to the assumption of how long the savings persist. The cost-benefit analysis of commissioning as a' stand-alone measure showed that benefits are greater than the costs for six of the 16 buildings for the low lifetime scenario. Under the high lifetime case the benefits are greater than the costs at ten of the 16 sites. When considering the costs and benefits of commissioning and the EEMs combined, the benefits exceed the costs for ten buildings for both the low and high lifetime case. Implications This study has shown that for most buildings, the investment in commissioning was cost effective based on energy savings alone. Energy prices are low in the Pacific Northwest, and the cost-effectiveness would be higher in other regions of the U.S. The findings are subject to significant uncertainty because of the small sample size and lack of metered data in the evaluation; additional case study analysis i s needed. However, the finding suggests that utility sponsored commissioning should be considered in demand-side management activities. In an era when utilities and energy providers are positioning themselves for a deregulated energy marketplace, companies that offer performance ce assurance and commissioning are likely to be at a n advantage because of, their more direct involvement in understanding and addressing customer's needs. Building owners want buildings that work as intended, are comfortable, healthy, and efficient. Looking beyond energy savings benefits, it is likely that the non-energy benefits outweighed the'costs at the several of the sites. The owners are generally not well informed, however, about the benefits of commissioning. The distinction between EEM and whole-building commissioning was blurred, especially among the large buildings. This suggests the need to commission not only the most energy-saving EEMs, but the most energy-consuming building systems: Greater use of metering, Energy-Management and Control System trend-logs, and enhanced links to O&M will help improve the effectiveness of commissioning by increasing the ability to evaluate its value and ensure persistence.of savings from deficiency corrections. vi *
