ENVIRONMENTAL IMPACT ASSESMENT APPLYING INDICATORS EMBEDDED INTO A SOCIAL HOUSING BIM MODEL

Abstract

In Europe, construction activity consumes 40% of the primary energy, while it generates 36% of the CO2 emissions and 40% of the Construction & Demolition Waste (CDW). European Directives on sustainable building foster the implementation of digital tools to promote an efficient use of natural resources and raw materials, as they pursue nearly zero building, and waste reduction, reuse and recycling goals for 2020. Thus, Building Information Modelling (BIM) may be a versatile tool to manage the whole building life cycle stages: building design, construction and demolition. This work proposes to embed embodied energy (EE), carbon emissions (CE), Construction & Demolition Waste (CDW), and Urban Solid Waste (USW) indicators into a residential block concrete structure BIM model. Material takeoff schedules automatically extract the new parameters from BIM families and types to quantify the environmental indicators. As it focuses on the early stages of design to assess the building environmental impact, designers may deliver eco-efficient solutions that will mostly determine the building environmental performance along its life cycle while keeping control on design aspects
