With the increasing awareness of sustainable development in the Russian construction industry, implementation of an energy rating procedure to assess buildings is becoming more important. The most representative building environment assessment schemes that are in use today are Building Research Establishment Environmental Assessment Method (BREEAM) and Leadership in Energy and Environmental Design (LEED). This paper aims to focus on the investigation of energy performance assessment for new buildings including the Russian experience within the BREEAM and LEED schemes. A review of the two schemes with regards to their assessment methods, scopes, performance criteria and energy rating scales are presented. Through this study, an attempt is made to make clear how building energy performance is assessed and therefore awarded with energy credits under the international schemes and to form a good basis for future development of a generic energy assessment framework of Russian Federation.

The climate is changing very fast today, and this is not natural. We are experiencing the impact of climate change in many aspects. It is also expected to impact the performance of buildings badly in due course of time. In recent years, many countries started investing to evaluate the energy performances of the buildings and opting for the best suited energy-saving measures. However, this concept may be new in the context of Bhutan. However, the author expects that this new concept may revolutionize the building construction sectors in Bhutan. Many studies show that buildings are one of the world’s largest consumers of energy, and on the other hand, strategies are available to reduce energy consumption. The strategies can be applied right from the design phases for the new buildings and retrofits for the old buildings. In order to apply the best strategies of energy consumption reduction and to understand building energy consumption patterns, an evaluation of the building’s energy performance needs to be carried out.

Abstract To boost the energy performance of buildings, the EU has established a legislative framework including the Energy Performance of Buildings Directive (EPBD). Through this document, EU state members are incentivized to set up a Building Energy performance Assessment Method (BEAM), tailored to the specific needs of the country. There is no standard definition for the energy performance of a building. Since the options are numerous, it is important for the policymaker to define the goals of their specific BEAM first, before developing the BEAM itself. The definition of these goals is a subjective matter and can differ when asked to different organizations in the building sector. To comprehend the desires and perspectives from each different group, a structured overview of the goals that are important for the specific region is needed. For this paper, a method was developed to provide this structured overview and was tested on the legislative energy performance of buildings (EPB) framework of Flanders, Belgium. The Flemish framework was initiated in 2006 and is still in action today. The method consists of two steps. In the first step, a multi-level tree structure for goal mapping based on the Goal Breakdown Structure (GBS) was developed. The main goal, reducing global warming, is on top of the tree structure, which then subdivides into many sub-goals on different levels. An example of a goal on the lowest level of the structure could be the insulation level of the walls. In the second step, prominent stakeholders in the Flemish building industry, including policymakers, researchers, manufacturers, contractors and building owners, were surveyed to capture their expectations from a BEAM and to query whether the current BEAM corresponds with those expectations. The goal of this survey was to receive qualitative, not quantitative input from the stakeholders. In total, 33 respondents completed the survey. The survey results showed that, in general, the desired goals have not changed substantially compared to the pre-set goals in 2006. Trias Energetica is still the preferred guideline for the decision-making process of the building owner, although its absolute power has decreased slightly and seems to be more prone to the conditions. The current indicator for the overall energy needs (E level) is still strongly preferred, while the recently introduced S level (assessment of the envelope) attracts mixed feelings in terms of usefulness to the entire EPB framework. The overheating indicator receives the most critique for not being accurate enough due to the simplified, single zone BEAM

In recent years, many researchers across the world have addressed the implementation of Building Information Modelling (BIM) in the energy assessment of the built environment. However, several potential issues still need to be resolved in order to utilise the benefits provided by BIM to a maximum degree. To fill this gap, a systematic literature review is conducted in this study to critically investigate the utilisation of BIM tools in energy assessment. To achieve the above-mentioned objective, after shortlisting the relevant papers published hitherto, using keyword searching, a systematic review was undertaken, including the application of BIM in the contexts of different countries, types of BIM tools, BIM and Life Cycle Assessment (LCA) integration, energy affiliations, stakeholders’ involvement and their roles, uncertainty, and sensitivity analysis. The outcomes show the most widely used and effective BIM tools in different types of construction projects in various countries. The review of the literature clearly shows that BIM tools can effectively be used in the assessment of energy performance of buildings. The article gives insight to engineers, architecture, and decision makers to carefully select appropriate BIM tools in terms of energy assessment.

Researchers have recently called for a greater emphasis on the use of functional assessment procedures in the selection of treatment strategies for problem behavior in persons with mental retardation. In applied settings there are several methods available for conducting a functional assessment. This article identifies and describes three methods that have been used in applied behavior analysis research: informant assessment (e.g., behavioral interviews, rating scales, and questionnaires), direct observation assessment, and experimental analysis. Although experimental analysis provides the most conclusive information regarding controlling variables for a behavior problem, less rigorous methods of assessment also yield important information with which to select and evaluate treatment strategies. This article reviews the strengths and weaknesses of each functional assessment method and provides a case example to illustrate the use of the various assessment procedures.

Building Energy Codes

Building energy codes are key policy tools for improving building energy efficiency by defining the minimum requirement for the energy performance of new buildings. In Korea, the building energy code was focused on prescriptive criteria for a long time but is now gradually introducing performance criteria. However, switching to performance criteria is not straightforward because of the resistance of the market to abandoning the well-consolidated prescriptive criteria. The objective of this study is to derive appropriate measures to strengthen the prescriptive criteria and the performance criteria, considering both the energy-saving effect and the economic efficiency for new office buildings and educational buildings to increase the market acceptance of the building energy codes. To this end, the energy-saving effects of reference buildings resulting from the reinforcement of the prescriptive criteria in the past have been first analyzed. Then, based on the collected energy performance parameters and cost data, the economic efficiency relative to the energy saving deriving from the application of passive and active energy conservation measures (ECMs) were analyzed, and future building energy code’s reinforcement measures were derived.

This research tries to investigate, in the current condition of the Italian real estate market, the economic advantage of investing in energy retrofitting of existing buildings or in expenditure aimed at obtaining higher energy performances in the construction phase of new buildings. A cost-benefit analysis is developed referring to the construction industry entrepreneur. Firstly, the increase in value due to a different measurement of the energy performance of new buildings or newly redeveloped residential buildings is achieved through an innovative statistical approach. Energy performance is measured by taking as a reference the category of energy certification, as required by European legislation. In the estimate of the contribution, the measurement of energy performance, expressed on an ordinal scale, is treated as a categorical variable in the implementation of an iterative regression model, called the alternating least squares model. Afterwards, this contribution is compared to the cost of sustainable building, trying to define a percentage increase in cost compared to a minimum condition according to different and increasing levels of energy performance. In the developed case studies, the comparison between likely benefits and investment spending showed that the entrepreneur would have no convenience at an expense for energy retrofitting while obtaining a positive balance in the construction phase of new buildings. The financial advantage grows if the investment is aimed at achieving the best energy performance and in areas where the price level of the real estate market is lower. The finding can be used as a guide for construction industry investors to make decisions in energy-efficient residential buildings production or transformation.

Building energy certification is stipulated by law in the majority of the European countries. The intention of these regulations is to offer key performance indicators (KPIs) to relevant and interested stakeholders. Another motivation for implementing these calculation schemes was to compare the energy performance of different buildings. However, existing guidelines for building energy evaluation do not comprehensively outline the input data collection process and the derivation of substantial KPIs. Furthermore, practitioners do not share a common understanding of the approach to energy certificates, resulting in different practical methods and different interpretations of the calculation guidelines. As a result, the envisioned comparability between buildings is not ensured, as a number of studies illustrated in the past.This contribution focuses on a specific uncertainty in building energy evaluation input data, pertaining to zoning and usage assumptions. Toward this end, two case studies are presented. A number of existing buildings (typical Viennese building stock) were subjected to the Austrian normative energy certification calculation. Thereby, different scenarios regarding the zoning and usage profiles of the buildings were developed. On the one hand, the calculated performance of individual (residential) units was compared with the calculated performance of the whole building. On the other hand, calculations considering different usage assumptions in different zones within the building (detailed calculation) were compared to results based on generalized assumptions for the whole building. The evaluation of the case study buildings showed significant differences in KPIs, given different input data (depending on the case study, heating demand showed deviations up to 50%). The results emphasize the importance of a clear documentation of input data assumptions for building-related energy assessment.

Building greenery systems can represent a sustainable solution for new buildings design and for existing buildings retrofitting, in order to improve the thermal energy performance of buildings, to decrease building energy loads and to contrast the Urban Heat Island. Green façades can influence thermal properties of a building by means of different important mechanisms: the shading, the cooling, the insulating and the wind barrier effect. Moreover, green façades accomplish heating effect in the cold season and at nighttime. An experimental test was developed at small scale at the University of Bari (Italy) from 2014 to 2016 for testing two different green façades. The plant species chosen were Pandorea jasminoides variegated and Rhyncospermum jasminoides, two evergreen climbing plants. A third uncovered wall was used as control. The thermal behaviour of the plants was analysed during the 2016 summer season, by keeping in consideration the external surface temperature of the building and the temperature of the airgap behind the green vertical systems. The daylight temperatures observed on the plant-covered walls during representative days were lower than the respective temperatures of the uncovered wall up to 7.0°C. During nighttime, the temperatures behind the plants were higher than the respective temperatures of the control wall up to 2.2°C. The results shown in the present research allow delineating the behaviour of the two plant species during summer in the Mediterranean climate region.
