The emergence of Building Information Modeling (BIM) has transformed the construction industry and is reshaping how we deliver projects. At Skanska, BIM has been implemented during every phase of the project life cycle, from conceptual design through facility management. Using BIM along with sustainable design and construction techniques is referred to as “Green BIM.” Green BIM helps our project stakeholders make informed decisions early in the design process and enables a greater impact on the efficiency and performance of a construction project.
Using BIM in the design process helps us evaluate energy efficiency and make recommendations for design alternatives that will enhance a building’s performance. By combining BIM with specialized energy modeling software, every part of a building, from MEP (Mechanical, Electrical & Plumbing) systems to interior climate, can be simulated and optimized for energy efficiency.
Carbon footprinting with BIM helps us test conceptual designs so we can specify solutions with the lowest carbon impact. This allows us to identify low carbon options that have the potential to drive down carbon emissions during the design and construction phases, as well as options that lead to carbon savings during a building’s operation.
Tying BIM to materials can significantly reduce construction waste and streamline the supply chain through more accurate procurement. Like carbon footprinting, it also helps us select design solutions that can reduce the overall environmental impact of a building throughout its operation. While BIM has the potential to reduce waste on all construction projects, it is highly beneficial to large complex projects, which tend to generate significant waste if they are not carefully managed.
BIM helps to quantify the amount of water used in a building by calculating the number of fixtures (sinks, toilets, etc.) and their related water usage. This also helps us measure the potential for greywater reuse, which is highly beneficial for reducing demand on local water supplies. The amount of water available for harvesting can be calculated using BIM, based on the site, harvesting system, and the size of building.
