Energy benchmarking is a practical management tool to evaluate and improve the energy performance of an industrial firm, possibly revealing considerable potentials for energy savings and for reduction of emissions to the atmosphere and biosphere. Existing energy metrics used for energy benchmarking however are strictly limited to measuring energy efficiency, completely disregarding positive or negative effects energy savings may have on other environmental pressures (use of depletable resources other than energy, emissions of pollutants , effluents or waste). We therefore propose investigating the use of technical efficiency measures as energy benchmarking tools. Technical efficiency is explored from both an engineering and a micro-economic approach, although we limit our discussion to the nonparametric mathematical programming performance measures. Particular attention is given to the inclusion of undesirable outputs or ‘bads’ in the existing performance measures. We conclude with a cursory review of empirical research done in the field of environmental performance indicators (EPIs), mainly in the sector of electricity generation and pulp and paper mills.

Summary The purpose of this paper is to introduce basic principles of benchmarking and explain the methodology to set the specific energy consumption (SEC) target for the beer and beverage industry in Vietnam to evaluate performance, support decisions, and energy efficiency (EE) improvement. Energy benchmarking management method is used to assess EE performance. This study also presents the SEC methodology as a guide for Vietnam enterprises in the brewery sector on how to manage the EE consumption and to comply with the legal energy consumption quota in the beer and beverage production. The study supports the enterprise in how to determine the SEC and support for national EE is essential to the promotion and deployment of practical energy-saving solutions and compliance with the SEC through a suitable energy-saving target. In addition, this paper is introducing the original SEC calculation in three cases of production in the beer and beverage industry including producing beer only, ...

Educational buildings are buildings with special social importance and their energy consumption requires particular attention. Since the majority of educational buildings in Serbia were built between 1950-1990, with concrete frame, brick walls and poor thermal insulation, it can be concluded that these buildings have relatively high potential for thermal energy savings. In this paper, specific heat consumption of educational buildings (42 different institutions classified throughout educational levels) in the city of Kragujevac (Serbia) was analysed in order to determine their specific heat consumption (per heated floor area and per user) and to list the priorities for refurbishment. According to educational level, they were classified in: preschool buildings, elementary and high schools and faculties (university buildings). Data about heat energy consumption were collected during several heating seasons in order to minimize the influence of seasonal climate variations. Values of specific heat energy consumption of the buildings were benchmarked with data on specific heat consumption of schools from different European countries. In order to accomplish the tasks, authors introduced the concept of weather normalised specific heat consumption. Results of the performed analysis pointed out preschool and elementary school buildings as refurbishment priorities since their average specific heat consumption is the biggest (186 kWh/m 2 /a and 176 kWh/ m 2 /a, respectively). Besides, normalised specific heat consumptions of the educational buildings in Kragujevac are higher than in comparing countries and the potential for their energy efficiency improvement is significant.

Voluntary approaches play an important role in reducing industrial energy use and CO2-emissions. Benchmarking can provide a starting point for negotiating targets, and are an added value to a monitoring program. Indicators are perfect for identifying the performance gaps, and to track performance over time. However, indicators at the firm level are still characterized by a low degree of standardization. Lack of comparability makes benchmarking very difficult. Indicators measure changes in one aspect (e.g. energy use) as if they were completely independent of changes in other aspects (e.g. waste generation). We argue that integrated indicators, based on micro-economic productivity theory, may one day assume the role of certified tools in the field of flexible policy instruments.
