![]() ![]() Tackling climate change requires responsible action towards carbon and greenhouse emissions. The UN SDGs 11 and 13 obligate Ghana, like many other developing countries, to work towards building of sustainable cities and communities by 2030 and make efforts to reduce adverse effects of climate change. Such tools revolve around the descriptors of sustainability, among which are the United Nations Sustainable Development Goals (UN SDGs). However, these assessment methods do not offer guidance on the incorporation of sustainability considerations as an integral part of design delivery. Assessment methods such as Building Research Establishment Environmental Method (BREEAM), Leadership in Energy and Environmental Design (LEED), and the Sustainable Building Tool (SbTool) among others, have been developed to guide designers in providing environmentally friendly solutions. Decisions made must be informed to make the process fluid and efficient. ![]() Consequently, designers have taken on a difficult, but important role, which requires in-depth knowledge on the environmental impacts of materials as analysis of building performance has significantly become more complex at the early design stages. The design of new buildings presents an opportunity for designers to make sustainable decisions to reduce environmental impacts and enhance human health. This assists designers in decision-making that consider environmental impacts of materials and energy consumption as part of sustainable building design considerations.ĭesigning buildings to respond to the wide and amorphous scope of sustainability requirements is challenging. The paper proposes a generic approach which has the potential to incorporate LCA as an integral part to the BIM-enabled design development process. Strategic definition, Preparation and briefing, and Concept design) and presents a systematic approach for BIM-based LCA estimation for the early design stages using the Business Process Modelling Notation. The framework aligns with the RIBA Plan of Work 2013 Stages 0–2 (i.e. The research considers both operational and embodied carbon effects of the design solution. A guidance framework for implementation of BIM-LCA supported by energy analysis has been developed to aid optimisation of sustainable design solutions based on simulations using Autodesk Revit as a BIM authoring tool, Green Building Studio and Tally to perform energy and LCA simulations on a hypothetical two-bedroom single-family house. ![]() This research aimed at studying the process of BIM-LCA integration to assist designers in making sustainable material and product selection decisions in Ghana. Integration of Building Information Modelling (BIM) and Life Cycle Assessment (LCA) is regarded as useful for making design decisions regarding the environmental and health impacts of building products and materials. ![]()
