AN APPROACH TO CIRCULAR BUILDING RENOVATION USING PRODUCT SERVICE CONCEPTS

Abstract

Accelerating the rate and depth of energy renovations in buildings is one of the biggestchallenges currently facing the construction industry. The increasing range and complexityof building technologies make product selection challenging. At the same time, we needto embrace new circular building strategies in which material waste is eliminated. In anongoing process materials and components are reused or remanufactured and canconstantly be replaced with new and more efficient ones. The paper describes the firstpilot project for a facade leasing at the Delft Technical University that explores ways ofimplementing circular construction methods. It acts as collaboration catalyst to furtherdevelop the complex system of contracts, financing structures, and operational servicesrequired to turn the facade leasing project into a feasible proposition. First generalconclusions are drawn concerning supply, demand side, financial and legal aspects.
