  1. The key to success? Using BIM to achieve zero emissionsIntegrating LCC-analysis and Carbon Footprint accountingA virtual project“The Statsbygg approach”TWN, Washington; september 18. - 21. 2011ØivindChristoffersen

  2. Background • LCC-analyse is an economic method that collocates investment with future expenses for management, operation, maintenance and development (www.lccweb.no, a tool developed by Statsbygg and Forsvarsbygg) • Carbon Footprint Account makes it possible to calculate life cycle-based GHG-emissions for buildings (www.klimagassregnskap.no , atool developed by Statsbygg) • It is now a legal requirement in Norway that Life Cycle Costs and environmental consequences must be considered when planning public procurements.

  7. A virtual project for zero-energy-buildings Virtually zero and entirely green • A ‘virtual project’: To project a nearly zero-energy building, in order to gain experiences before actually building. • A practical exercise for the partners involved • Cooperation in focus; with the industry and stakeholders. • Involving and engaging the users of the ‘building’ as early as possible. • Providing a good web site: concrete illustration of the building and its energy and environmental footprint. • The ‘building’ to gradually emerge – ‘physically’ – on the web site.

  8. Objectives of the project • Provide a knowledge base in order to actually build a Nearly zero-emission building before 2018,by focusing on: • An innovative concept together with industrial partners (across sectors) and stakeholders • Cooperation, involvement and transferability • Tools like BIM, GIS, LCC, Carbon accounting • Open, accessible info. during the whole project • Localisation and land-use (local authorities) • Renewable energy supply • Potential exchange with the grid. • Energy metering and management; implementing advanced tools and engaging the users of the building. • Coherent focus on complete environmental footprint.
