    Quality versus impact: Comparing the environmental efficiency of building properties using the EcoEffect tool2010In: Building and Environment, ISSN 0360-1323, E-ISSN 1873-684X, Vol. 45, no 5, 1095-1103 p.Article in journal (Refereed)
    Abstract [en]

    There are tools that are developed for the assessment of the environmental impact of buildings (e.g. ATHENA). Other tools dealing with the indoor and outdoor environmental quality of building properties (referred to as real estates in other literature) are also available (e.g. GBTool). A platform where both the aspects of quality and impact are presented in an integrated fashion are few. The aim of this contribution is to present how the performance of different building properties can be assessed and compared using the concept of environmental efficiency in a Swedish assessment tool called EcoEffect. It presents the quality dimension in the form of users' satisfaction covering indoor and outdoor performance features against the weighted environmental impact covering global and local impacts. The indoor and outdoor values are collected using questionnaires combined with inspection and some measurements. Life cycle methodology is behind the calculation of the weighted external environmental impact. A case study is presented to show the application of EcoEffect using a comparative assessment of Lindas and a Reference property. The results show that Lindas block is better in internal environment quality than the Reference property. It performs slightly worse than the Reference property in the external environmental impact due to emissions and waste from energy and material use. The approach of integrated presentation of quality and impact as in EcoEffect provides with the opportunity of uncovering issues problem shifting and sub-optimisation. This avoids undesirable situations where the indoor quality is improved through measures that result in higher external environmental impact.

    Environmental assessment of building properties — Where natural and social sciences meet: the case of EcoEffect2007In: Building and Environment, ISSN 0360-1323, E-ISSN 1873-684X, Vol. 42, no 3, 1458-1464 p.Article in journal (Refereed)
    Abstract [en]

    The EcoEffect method of assessing external and internal impacts of building properties is briefly described. The external impacts of manufacturing and transport of the building materials, the generation of power and heat consumed during the operation phase are assessed using life-cycle methodology. Emissions and waste; natural resource depletion and toxic substances in building materials are accounted for. Here methodologies from natural sciences are employed. The internal impacts involve the assessment of the risk for discomfort and ill-being due to features and properties of both the indoor environment and outdoor environment within the boundary of the building properties. This risk is calculated based on data and information from questionnaires; measurements and inspection where methodologies mainly from social sciences are used. Life-cycle costs covering investment and utilities costs as well as maintenance costs summed up over the lifetime of the building are also calculated.

    The result presentation offers extensive layers of diagrams and data tables ranging from an aggregated diagram of environmental efficiency to quantitative indicators of different aspects and factors. Environmental efficiency provides a relative measure of the internal quality of a building property in relation to its external impact vis-à-vis its performance relative to other building properties.

    Development of an environmental rating tool for buildings through a new kind of dialogue between stakeholders and researchers2009In: Archnet-IJAR : International Journal of Architectural Research, ISSN 1994-6961, E-ISSN 1938-7806, Vol. 3, no 1, 116-130 p.Article in journal (Refereed)
    Abstract [en]

    Buildings need to be more environmentally benign since the building sector is responsible for about 40% of all of energy and material use in Sweden. For this reason a unique cooperation between companies, municipalities and the Government called “Building-Living and Property Management for the future”, in short “The Building Living Dialogue” has going on since 2003. The project focuses on: a) healthy indoor environment, b) efficient use of energy, and c) efficient resource management. In accordance with the dialogue targets, two research projects were initiated aiming at developing an Environmental rating tool taking into accounts both building sector requirements and expectations and national and interna-tional research findings. This paper describes the first phase in the development work where stake-holders and researchers cooperate. It includes results from inventories and based on this experience discusses procedures for developing assessment tools and what the desirable features of a broadly accepted building rating tool could be.

    A concept for environmental management of chemicals in the building process2005In: INDOOR AIR 2005: PROCEEDINGS OF THE 10TH INTERNATIONAL CONFERENCE ON INDOOR AIR QUALITY AND CLIMATE, VOLS 1-5 / [ed] Yang, X; Zhao, B; Zhao, R, 2005, 1048-1053 p.Conference paper (Refereed)
    Abstract [en]

    This study was carried out within the frame of the "EcoEffect Environmental Assessment System for Buildings". The aim was to develop a coherent system to identify hazardous chemicals in new buildings. A survey of the Swedish building sector environmental management systems of chemicals was made and two case studies were carried out to analyze their outcomes in ongoing building projects. A concept for more efficient environmental management of building chemicals including routines for data collection and presentation of potential risks associated with them was suggested. To visualize these risks a hazardous profile was developed as a bar diagram with well-known effects. The bars are calculated amount and classification of chemical substances. Special attention has been given to heavy metals, carcinogenic, mutagenic and reprotoxic substances and organic substances that are persistent, bioaccumulating and toxic. Chemicals such as phthalates that are associated to allergic symptoms in indoor environment have been taken into account.

    Selecting aspects and indicators in environmental assessment methods for buildings2007In: PORTUGAL SB07 - SUSTAINABLE CONSTRUCTION, MATERIALS AND PRACTICES: CHALLENGE OF THE INDUSTRY FOR THE NEW MILLENNIUM / [ed] Braganca L; Pinheiro M; Jalali S; Mateus R; Amoeda R; Guedes MC, AMSTERDAM: I O S PRESS , 2007, 326-333 p.Conference paper (Refereed)
    Abstract [en]

    It is tacitly understood that comprehensive environmental assessment methods cover the most significant environmental aspects of the intended assessment conditions. However, depending on the purpose and target-group of the method, more or fewer aspects and indicators may be included. In the development process of a Swedish environmental rating method for buildings, different approaches for selecting aspects were discussed and tested. In addition, possible indicators that measure the selected aspects were tested with regard to their environmental relevance, cost-effectiveness, etc. This procedure thus enabling a discussion of the appropriateness of different indicators used in existing environmental assessment methods for buildings. The analysis of this paper is restricted to indoor environmental quality (IEQ) but can be applied on all assessment areas of similar methods.

    Selecting problem-related environmental indicators for housing management2006In: Building Research & Information, ISSN 0961-3218, E-ISSN 1466-4321, Vol. 34, no 4, 321-333 p.Article in journal (Refereed)
    Abstract [en]

    The performance of environmental management systems is difficult to evaluate due to insufficient methods for measuring their environmental impacts. A procedure is proposed that contains more environmentally relevant indicators for assessing environmental impacts. In addition, theoretical and practical criteria are suggested for evaluating the relevance of different indicators. This scheme was applied to the housing-management sector with the aim of finding more problem-related indicators. Data from three existing Swedish housing estates were collected and indicators calculated for three environmental aspects: energy use, household waste treatment and embedded toxic substances/materials. The results show that problem-related environmental indicators can be used in the housing sector to measure energy consumption and, to a certain extent, household waste treatment. Finding indicators for embedded toxic substances was found to be more problematic, but an example for further discussion is presented.

    Life Cycle Assessment in Buildings: the ENSLIC simplified method and guidelines2011In: Energy, ISSN 0360-5442, E-ISSN 1873-6785, Vol. 36, no 4, 1900-1907 p.Article in journal (Refereed)
    Abstract [en]

    The application of Life Cycle Assessment (LCA) in the building sector is scarce today. It has several causes. First of all, making a LCA evaluation of a whole building demands a specific tool to handle the large information needed. Further, this tool has to be adapted to the different decisions taken throughout the building life cycle. In a few countries such tools have been developed but they are exceptions. However, useful experience has been gained in these countries, which is a valuable source for developing guidelines for application in other countries. Since results of building’s LCA may contain abundant and complex information, a great challenge is to elaborate efficient ways for communication with users and clients.

    The simplified methodology and guidelines presented in this paper is a systematic approach guiding the user through the Life Cycle process - clarifying key issues which usually cause difficulty, such as the choice of the assessment tool, the definition of the system limits, the options for simplifying the process, etc. The guidelines have been developed in the framework of the “ENSLIC building project”, co-financed by the European Commission-Intelligent Energy for Europe Programme- and by 9 European Organisations including more than 15 LCA experts and architects.

    A Swedish environmental rating tool for buildings2011In: Energy, ISSN 0360-5442, E-ISSN 1873-6785, Vol. 36, no 4, 1893-1899 p.Article in journal (Refereed)
    Abstract [en]

    In 2003, a joint effort between the Swedish government, a number of companies in the building and construction sectors, some municipalities, insurance companies and banks set a target that by 2009, all new buildings and 30% of existing Swedish buildings should be rated using a voluntary environmental rating tool. In a major research programme finished in 2008, a tool was developed to be used in this context. The tool covers three assessment areas: Energy, Indoor environment and Material & Chemicals. These areas are split into 11 aspects with one or a few indicators. Rating criteria are specified for each indicator, stipulating requirements for a rating Gold, Silver, Bronze and Rated. Indicator results can then be aggregated to aspect, area and a single raring for building level for enhanced result communication. The tool builds on previous experiences regarding environmental building rating tools and therefore includes some special characteristics which aim to tackle some of the criticism directed towards the first generation of such tools. At the time of writing, the first buildings have received official ratings and an independent stakeholder group is promoting broader implementation of the tool. (C) 2010 Elsevier Ltd.

    Design consequences of differences in building assessment tools: a case study2011In: Building Research & Information, ISSN 0961-3218, E-ISSN 1466-4321, Vol. 39, no 1, 16-33 p.Article in journal (Refereed)
    Abstract [en]

    Environmental assessment tools for buildings are emerging rapidly in many countries. Do different assessment tools influence the design process and also guide 'green' building projects in different directions? Three assessment tools, Leadership in Energy and Environmental Design for New Construction (LEED-NC), Code for Sustainable Homes (CSH) and EcoEffect, were tested in a case study project in Sweden: a new multi-storey residential building called Gronskar. The content and results of the three assessment tools were compared in general, while issues in the three core common categories of Energy, Indoor Environment and Materials Waste were compared in more detail. The assessment results for the case study building varied with the three tools, and the design strategies and tactics to improve the overall rating of the building project differed for each tool. This confirms that the tools can influence sustainable building in different directions and illustrates insufficient consensus between assessment tools in terms of issues, criteria and weighting. The divergent results highlight the need for an appropriate structure of assessment tools that are both environmentally relevant and practically useful. 'on assiste dans de nombreux pays a l'emergence rapide d'outils d'evaluation environnementale. Des outils d'evaluation differents influent-ils sur le processus de conception et orientent-ils egalement les projets de batiments << verts >> dans des directions differentes? Trois outils d'evaluation, le systeme Leadership in Energy and Environmental Design for New Construction (LEED-NC pour les constructions neuves), le Code for Sustainable Homes (Code pour des Logements Durables - CGH) et EcoEffect, ont ete testes dans le cadre d'un projet de construction situe en Suede et utilise comme etude de cas : un nouvel immeuble residentiel a etages multiples denomme Gronskar. Le contenu et les resultats de ces trois outils d'evaluation ont ete compares sur un plan general, tandis que les points relevant des trois principales categories communes - Energie, Environnement Interieur et Materiaux et Dechets - ont ete compares de maniere plus detaillee. Concernant l'immeuble utilise comme etude de cas, les trois outils ont donne des resultats d'evaluation qui differaient, et les strategies et tactiques de conception visant a ameliorer la notation globale du projet de construction etaient differentes pour chaque outil. Ceci confirme que ces outils peuvent influer sur un batiment durable a differents niveaux et illustre le consensus insuffisant entre les outils d'evaluation en termes d'enjeux, de criteres et de ponderation. Ces resultats divergents soulignent la necessite de pouvoir disposer d'outils d'evaluation presentant une structure adaptee pour que ceux-ci soient a la fois pertinents pour l'environnement et d'une utilite pratique.

    Framework for Detailed Comparison of Building Environmental Assessment Tools2013In: Buildings, ISSN 2075-5309, E-ISSN 2075-5309, Vol. 3, no 1, 39-60 p.Article in journal (Refereed)
    Abstract [en]

    Understanding how Building Environmental Assessments Tools (BEATs) measure and define “environmental” building is of great interest to many stakeholders, but it is difficult to understand how BEATs relate to each other, as well as to make detailed and systematic tool comparisons. A framework for comparing BEATs is presented in the following which facilitates an understanding and comparison of similarities and differences in terms of structure, content, aggregation, and scope. The framework was tested by comparing three distinctly different assessment tools; LEED-NC v3, Code for Sustainable Homes (CSH), and EcoEffect. Illustrations of the hierarchical structure of the tools gave a clear overview of their structural differences. When using the framework, the analysis showed that all three tools treat issues related to the main assessment categories: Energy and Pollution, Indoor Environment, and Materials and Waste. However, the environmental issues addressed, and the parameters defining the object of study, differ and, subsequently, so do rating, results, categories, issues, input data, aggregation methodology, and weighting. This means that BEATs measure “environmental” building differently and push “environmental” design in different directions. Therefore, tool comparisons are important, and the framework can be used to make these comparisons in a more detailed and systematic way.

    Basic building life cycle calculations to decrease contribution to climate change: Case study on an office building in Sweden2011In: Building and Environment, ISSN 0360-1323, E-ISSN 1873-684X, Vol. 46, no 10, 1863-1871 p.Article in journal (Refereed)
    Abstract [en]

    This study examined whether simplified life cycle-based calculations of climate change contributions can provide better decision support for building design. Contributions to climate change from a newly built office building in Gavle, Sweden, were studied from a life cycle perspective as a basis for improvements. A basic climate and energy calculation tool for buildings developed in the European project ENSLIC was used. The study also examined the relative impacts from building material production and building operation, as well as the relative importance of the impact contributions from these two life cycle stages at various conditions. The ENSLIC tool calculates operational energy use and contributions to climate change of a number of optional improvement measures. Twelve relevant improvement measures were tested. The most important measures proved to be changing to CO2 free electricity, changing construction slabs from concrete to wood, using windows with better U-values, insulating the building better and installing low-energy lighting and white goods. Introduction of these measures was estimated to reduce the total contribution to climate change by nearly 50% compared with the original building and the operational energy use by nearly 20% (from 100 to 81 kWh/m(2) yr). Almost every building is unique and situated in a specific context. Making simple analyses of different construction options showed to be useful and gave some unexpected results which were difficult to foresee from a general design experience. This process acts as an introduction to life cycle thinking and highlights the consequence of different material choices
