“…With the global demand on new buildings expect to grow steadily there is a substantial push towards more sustainable and resilient buildings. Many strategies have been introduced to improve building performance, such as green buildings, zero-energy buildings and building rating systems (Belussi et al, 2019;Hasik et al, 2017;Najjar et al, 2019;Shan and Hwang, 2018). LCA is one of the most popular tools to evaluate building performance, as it provides ways to access the resource and emission flows of a building throughout its service life (Hoxha et al, 2017;Nwodo and WBLCA at the building level 109…”

PurposeWhole building life cycle assessment (WBLCA) is a key methodology to reduce the environmental impacts in the building sector. Research studies usually face challenges in presenting comprehensive LCA results due to the complexity of assessments at the building level. There is a dearth of methods for the systematic evaluation and optimization of the WBLCA performance at the design stage. The study aims to develop a design optimization framework based on the proposed WBLCA method to evaluate and improve the environmental performance at the building level.Design/methodology/approachThe WBLCA development method is proposed with detailed processes based on the EN 15978 standard. The environmental product declaration (EPD) methods were adopted to ensure the WBLCA is comprehensive and reliable. Building information modeling (BIM) was used to ensure the building materials and assembly contributions are accurate and provide dynamic material updates for the design optimization framework. Furthermore, the interactive BIM-LCA calculation processes were demonstrated for measuring the environmental impacts of design upgrades. The TOPSIS-based LCA results normalization was selected to conduct the comparisons of various building design upgrades.FindingsThe case study conducted for a residential building showed that the material embodied impacts and the operational energy use impacts are the two critical factors that contribute 60–90% of the total environmental impacts and resource uses. Concrete and wood are the main material types accounting for an average of 65% of the material embodied impacts. The air and water heating for the house are the main energy factors, as these account for over 80% of the operational energy use. Based on the original WBLCA results, two scenarios were established to improve building performance through the design optimization framework.Originality/valueThe LCA results show that the two upgraded building designs create an average of 5% reduction compared with the original building design and improving the thermal performance of the house with more insulation materials does not always reduce the WBLCA results. The proposed WBLCA method can be used to compare the building-level environmental performances with the similar building types. The proposed framework can be used to support building designers to effectively improve the WBLCA performance.

“…A resilience index developed by [17] quantifies the resilience of a building as a function of "robustness, resourcefulness, and recovery" within the context of maintaining building functionality when faced with unique hazards. An "energy provision" metric developed by [18] assesses the ability of a building to provide energy during a disruption, with more specific metrics including natural/mechanical ventilation potential, air filtration, and daylight coverage. Criteria-based building resilience and sustainability rating systems and certifications, such as LEED [19], RELi 2.0 [20], US Resiliency Council Building Rating System [21], and BREEAM (Building Research Establishment Environmental Assessment Method) [22] aim to assess building resilience mostly through "feature-based" verification [23], which provides a prescriptive path to resilience, but does not necessarily take the form of explicit resilience metrics.…”

Increasing concern over higher frequency extreme weather events is driving a push towards a more resilient built environment. In recent years there has been growing interest in understanding how to evaluate, measure, and improve building energy resilience, i.e., the ability of a building to provide energy-related services in the event of a local or regional power outage. In addition to human health and safety, many stakeholders are keenly interested in the ability of a building to allow continuity of operations and minimize business disruption. Office buildings are subject to significant economic losses when building operations are disrupted due to a power outage. We propose “occupant hours lost” (OHL) as a means to measure the business productivity lost as the result of a power outage in office buildings. OHL is determined based on indoor conditions in each space for each hour during a power outage, and then aggregated spatially and temporally to determine the whole building OHL. We used quasi-Monte Carlo parametric energy simulations to demonstrate how the OHL metric varies due to different building characteristics across different climate zones and seasons. The simulation dataset was then used to develop simple regression models for assessing the impact of ten key building characteristics on OHL. The most impactful were window-to-wall ratio and window characteristics. The regression models show promise as a simple means to assess and screen for resilience using basic building characteristics, especially for non-critical facilities where it may not be viable to conduct detailed engineering analysis.

Abstract-The paper reveals regularity in solid phase materials property change depending on their capability of structural changes. A classification of technogenic waste is proposed that takes into account the condition of their production (biogenic, chemogenic, pyrogenic and mechanogenic) and nature of structural and property changes. Technogenic wastes may serve and are already serving as a source of raw materials for industry. Recommended waste conversion technology for production of construction materials is given for each group of waste. As an example, a possibility of pyrogenic waste conversion and recovery that takes into account the structural instability of the materials is shown. In this case, the structure may be stabilized by a corresponding method of primary processing or the existing structural instability may be used in the composite synthesis technology. A rational recovery scheme that influences the structure of the material is proposed for chemogenic waste in the form of galvanic sludge. Recovery of galvanic sludge may proceed both with and without extraction of metals as additional product.
