This research paper addresses the marketplace confusion and barriers that can prevent easy and well informed environmentally preferable material selections from being integrated into residential renovation projects in the Toronto region. It establishes a template for an easy-to-use material assessment toolbox that considers environmental impact categories that reveal variation between products of similar type and that are often considered together as "eco-friendly" options. The material assessment tool developed as a result of this research provides a resource that satisfies the Toronto-based needs of both client and contractor to assess and source environmentally preferable material choices common to most residential renovations work and to understand the up-front cost implications of these choices.

Building Life Cycle

Knowledge and research tying the environmental impact and embodied energy together is a largely unexplored area in the building industry. The aim of this study is to investigate the practicality of using the ratio between embodied energy and embodied carbon to measure the building’s impact. This study is based on life-cycle assessment and proposes a new measure: life-cycle embodied performance (LCEP), in order to evaluate building performance. In this project, eight buildings located in the same climate zone with similar construction types are studied to test the proposed method. For each case, the embodied energy intensities and embodied carbon coefficients are calculated, and four environmental impact categories are quantified. The following observations can be drawn from the findings: (a) the ozone depletion potential could be used as an indicator to predict the value of LCEP; (b) the use of embodied energy and embodied carbon independently from each other could lead to incomplete assessments; and (c) the exterior wall system is a common significant factor influencing embodied energy and embodied carbon. The results lead to several conclusions: firstly, the proposed LCEP ratio, between embodied energy and embodied carbon, can serve as a genuine indicator of embodied performance. Secondly, environmental impact categories are not dependent on embodied energy, nor embodied carbon. Rather, they are proportional to LCEP. Lastly, among the different building materials studied, metal and concrete express the highest contribution towards embodied energy and embodied carbon.

Green Building Materials

Green building materials have brought fundamental changes to the traditional construction methods, enabling better environmental protection and energy-saving performance of the buildings. However, due to the various material types and the large property differences, until now there isn’t a uniform evaluation index system (EIS) for green building materials, the existing studies on the green-level evaluation of green building materials during production and use are insufficient, and the research on energy-saving design is just getting started. For this reason, this paper attempted to launch a research on the multi-objective energy-saving optimization design of buildings based on the application of green building materials. First, the quantification method for the environmental impact factors of green building materials was elaborated, and the intervals and standards of the quantification evaluation were given; then, a green building material optimization selection model was constructed, and a multi-objective energy-saving optimization algorithm was proposed; at last, experimental results gave the green levels of a few candidate green building materials and the scores of the environmental impact factors, which had verified the effectiveness of the proposed algorithm.

Life Cycle Impact Assessment (LCIA) is a phase of the Life Cycle Assessment (LCA) in order to quantify various environmental impacts based on the inventory analysis. Weighting although is not the mandatory element of LCIA is the element in which local data becomes important. Potential environmental impacts and the importance of particular impacts can be quite significant among the countries or regions. Determination of the importance degree is possible by weighting of the selected environmental impact categories. Therefore, this study aimed to develop local weighting factors (WFs) by taking the environmental issues into consideration for the building materials produced in Turkey. And 11 environmental impact categories such as global warming, ozone depletion, acidification, photochemical ozone formation, eutrophication, fossil fuel depletion, mineral resource depletion, water depletion, land use, indoor air quality and waste were selected considering environmental impacts caused by the building materials and environmental issues in Turkey. And WFs of these categories for Turkey were determined by using a panel approach. Thus, it can be possible to assess environmental impacts of building materials by using local data.

This study analyzed the characteristics of the environmental impacts of apartment buildings, a typical housing type in South Korea, as part of a research project supporting the streamlined life cycle assessment (S-LCA) of buildings within the G-SEED (Green Standard for Energy and Environmental Design) framework. Three recently built apartment building complexes were chosen as study objects for the quantitative evaluation of the buildings in terms of their embodied environmental impacts (global warming potential, acidification potential, eutrophication potential, ozone layer depletion potential, photochemical oxidant creation potential, and abiotic depletion potential), using the LCA approach. Additionally, we analyzed the emission trends according to the cut-off criteria of the six environmental impact categories by performing an S-LCA with cut-off criteria 90–99% of the cumulative weight percentile. Consequently, we were able to present the cut-off criterion best suited for S-LCA and analyze the effect of the cut-off criteria on the environmental impact analysis results. A comprehensive environmental impact analysis of the characteristics of the six environmental impact categories revealed that the error rate was below 5% when the cut-off criterion of 97.5% of the cumulative weight percentile was applied, thus verifying its validity as the optimal cut-off criterion for S-LCA.
