摘要

Renovating buildings can be an important way to reduce the environmental impact of the outdated building stock. In reality the environmental aspect is rarely the sole concern for making renovation decisions and both the environmental and financial aspect need to be taken into account for viable and comprehensive renovation solutions to arise. This paper researches the environmental and financial impact of facade renovation strategies designed for change through life cycle analysis (LCA) and life cycle cost assessment (LCC) respectively. Its goal is to propose a methodology to obtain facade renovation strategies that are optimal from both the environmental and financial viewpoint and to simultaneously highlight the similarities and the differences between an approach based on LCA and on LCC. The methodology composes facade renovation strategies step-by-step by evaluating the design variables of a facade: renovation system, material combination, insulation thickness and window type. Environmental-financial optimal solutions of the design variables are determined using the Pareto front. The eventual Pareto front consists of environmental-financial optimal facade renovations fulfilling the predetermined boundary conditions. The results show that material and construction choices that are both financially and environmentally beneficial can be made. For the environmental impact the operational energy has the largest contribution and energy renovation measures will often be beneficial. For the life cycle cost the investment cost is the most important and energy efficiency measures will only pay off to a certain extent.
