Achieving Energy efficiency in Buildings is one of the national Key Performance Indicators in many countries. Because Major part of the generated energy is consumed by buildings, it is evident that achieving energy efficiency in buildings compliments in conservation of energy and its resources along with attaining sustainability. This research work is analysis of such building energy efficiency recommendations for Enhancing energy efficiency in buildings. The recommendations discussed in this paper were proposed by United Nations Economic commission for Europe (UNECE) for UNECE region consisting of 56 member countries. This paper analyses the UNECE recommendations, their cause and effects through Decision making trial and evaluation laboratory (DEMATEL) methodology. The results showed that among all the recommendations, the two that had greater potential in achieving the goal of energy efficiency in buildings are a) National and local authorities’ coordination for continuous development and implementation of building codes and b) Energy policy and legislation. The paper also discusses managerial applications of this research work and provides insight into the recommendations.

AbstractWith the advent of the smart grid era, the electrical grid is becoming a complex network in which different technologies coexist to bring benefits to both customers and operators. This paper presents a methodology for analyzing Key Performance Indicators (KPIs), providing knowledge about the performance and efficiency of energy systems, focusing on the demand side. In the first stage of the methodology, the baseline KPIs are calculated. In the second stage, all KPIs are updated to be compared with the baseline ones. In fact, due to the dynamic nature of players in a smart grid, this methodology plays a crucial role in the performance assessment. Moreover, the proper definition and selection of KPIs is usually a challenging task since KPIs can be applied to evaluate diverse areas within a smart grid. Such areas include building energy efficiency, home communications, and smart metering deployment, just to mention a few. In the proposed methodology, the information obtained from a KPI can be driven to distinct aspects such as efficiency, environment, reliability, power quality, safety, security, or cost reduction. Through a case study from a real implementation of an energy system, we show how to assess energy consumption efficiency, thus improving energy management.

We investigate the factors (“drivers”) that motivated investment in energy efficiency in commercial real estate office buildings over the 2006–2011 and 2012–2017 period, and looking forward from 2018 in the context of growing concern over carbon emissions around the world. These insights were collected from large Canadian asset managers through interviews conducted in 2017 and 2018. Key findings were that (1) organizations noted an increasing number of factors driving investment decisions over the three periods; (2) cost drivers (payback period and anticipated financial returns) were the top two drivers in 2006–2017; (3) public relations factors became significantly more important looking forward, with brand (reputational impact) as the top-ranked driver and tenant attraction tied for third place; and (4) mitigation against risks such as resilience and anticipated compliance consistently increased in importance. This study contributes to a comprehensive understanding of past, present, and near-future sustainable real estate investment priorities, changing owner behaviors, and the perceived business case for building energy efficiency investments.
