“…Therefore, in this research, the additional scenarios were proposed maintaining the same materials for roof and facade but looking for the preferred insulation thickness. This limitation is seen as justified as previous studies have shown that the type of insulation material does not provide essential differences in the life cycle impact and cost of a building [46,47]. For the definition of these additional scenarios roof, facade and windows were optimized separately, from both a life cycle environmental and financial perspective, i.e.…”

“…According to the reliability bathtub curve [24], the failure rate of the population is an approximately low constant before the end of the lifetime. Therefore an exponential decay model is adopted from [24] in equation (13). Let θ j i denote the MTBF of the facility, then k j i is obtained from the following equation:…”

“…For the building retrofitting investments, LCCA, a widely used technique for building retrofitting, can be applied to estimate the overall cost of the alternatives during the life-cycle of the building and evaluate the cost-effectiveness. Kaynakli [13] used LCCA to determine the optimal thickness of the insulation material in a building envelope for best cost-effectiveness. Menassa [14] presented a method to determine the investment of building retrofitting projects by taking into account different uncertainties associated with life-cycle cost and perceived benefits of this investment.…”

The building sector contributes a large proportion of the world's total final energy consumption. As a result, considerable attention has been paid to energy efficiency in the building sector. At the current stage, building retrofitting is the most feasible and cost-effective method to improve building energy efficiency. This paper presents a multi-objective optimization model for life-cycle cost analysis and retrofitting planning of buildings. A Net Present Value (NPV) based economic analysis taking life-cycle cost into account is introduced to formulate the objective functions. In addition, a combination of multiple alternative measures for each retrofitting intervention is considered in determining the optimal solution. The presented model aims at maximizing both energy savings and economic benefits during a selected time frame. It allows decision makers to make best use of the available budget. A Differential Evolution (DE) algorithm is proposed to solve this optimization problem. The result of the case study illustrates the effectiveness of the multi-objective optimization model to support the planning of energy-efficient and cost-effective building retrofitting projects.
