“…In the US, the residential and commercial businesses are responsible for 12% of the total greenhouse gas emissions due to heating and cooking needs, management of waste and wastewater, and leaks from refrigerants in homes and businesses [2]. It is essential to ensure sufficient energy supply in the future [3], and it is also necessary to incorporate measures for energy efficiency into the design and construction processes [4]. A major objective of sustainable design and construction is to minimize the adverse impacts of excessive energy consumption.…”

Abstract:Compared to other categories, the Energy and Atmosphere category contributes the most to the maximum obtainable points in the Leadership in Energy and Environmental Design (LEED) certification system. The objective of the study was to identify the extent to which project teams take advantage of the credits in the Energy and Atmosphere category of LEED. This study analyzes the performance of practitioners in achieving points in the Energy and Atmosphere credits of LEED-New Construction (NC) 2009 for 1500 buildings that received LEED certification in the US. For a better understanding of the credit patterns, the differences in the performance of practitioners are investigated relative to certification levels and project ownership. Achievement in credits is calculated in terms of percent of maximum points (PMP), since the maximum achievable points differ for each credit. Practitioners' achievements in the credits were ranked as follows: (1) enhanced commissioning, (2) optimized energy performance, (3) enhanced refrigerant management, (4) green power, (5) measurement and verification, and (6) on-site renewable energy. The largest achievement differences were observed in the on-site renewable energy credit. Concerning building ownership, investors were found to optimize mostly energy efficiency and on-site renewable energy, but to mostly skip enhanced refrigerant management. Performance in the measurement and verification credit was similar for all owner types, whereas investors performed differently from corporations, and government agencies in the enhanced commissioning credit. Practitioners who recognize these priorities and differences are expected to be better positioned to make sustainability-related decisions in building design and construction.

“…Even many national governments and international organization have developed new regulations, what is lacking today is the universal energy efficiency index for building. In order to address this issue Gonzalez et all [42] had proposed an energy efficiency index for buildings that relates the energy consumption within a building to reference consumption. The proposed energy index can be obtained in a simple manner by combination standard measurement, simulation and public data base; furthermore the index is upgradable whenever new data are available.…”

“…Moghimi et al [10] studied commercial buildings, analyzing indicators related to the occupied air conditioning area. González et al [11] suggested adopting a reference building to compare the energy consumption within a building stock. The work of Ballarini et al [12] pointed towards the same direction, explaining the experience of the Typology Approach for Building Stock Energy Assessment (TABULA) project (www.episcope.eu), applied to residential sector.…”

Abstract:We propose a simple tool to help the energy management of a large building stock defining clusters of buildings with the same function, setting alert thresholds for each cluster, and easily recognizing outliers. The objective is to enable a building management system to be used for detection of abnormal energy use. We start reviewing energy performance indicators, and how they feed into data visualization (DataViz) tools for a large building stock, especially for university campuses. After a brief presentation of the University of Turin's building stock which represents our case study, we perform an explorative analysis based on the Multidimensional Detective approach by Inselberg, using the Scatter Plot Matrix and the Parallel Coordinates methods. The k-means clustering algorithm is then applied on the same dataset to test the hypotheses made during the explorative analysis. Our results show that DataViz techniques provide quick and user-friendly solutions for the energy management of a large stock of buildings. In particular, they help identifying clusters of buildings and outliers and setting alert thresholds for various Energy Efficiency Indices.
