“…June 18, 2012 P. 2 A variety of protocols, tools, and standards are available from energy utilities and state, federal and private energy organizations as well as from research projects to guide the selection and implementation of energy retrofits for homes [2][3][4][5][6][7][8][9][10]. Additionally, more sophisticated and time consuming algorithm-based approaches to identify retrofit strategies exist [11,12]. The above-mentioned protocols, tools, and standards seek to maximize energy savings per unit expenditure, and often employ energy modeling, cost-benefit estimation, and engineering judgment.…”

The current focus on building energy retrofit provides an opportunity to simultaneously improve indoor environmental quality (IEQ). Toward this end, we developed a protocol for selecting packages of retrofits that both save energy and improve IEQ in apartments. The protocol specifies the methodology for selecting retrofits from a candidate list while addressing expected energy savings, IEQ impacts, and costs in an integrated manner.Interviews, inspections and measurements are specified to collect the needed input information. The protocol was applied to 17 apartments in three buildings in two different climates within California. Diagnostic measurements and surveys conducted before and after retrofit implementation indicate enhanced apartment performance.

“…Table 8 defines the technical parameter for electrical and thermal storage technologies. Since this work is intended to show the trade-off between energy cost and CO 2 emission reduction, DER-CAM allows optimizing the weighted building energy costs and CO 2 emissions at the same time by using a multi-objective approach described by equation (11). By increasing ω, more focus on CO 2 emission reduction is placed.…”

“…The Campus building is used as an office complex and for education purposes. While DER-CAM considers hourly load profiles and their effects on building shell refurbishment other work as described in [11,12] is based on yearly consumptions and small sets of technologies (window exchange, additional wall and roof insulation, and solar collectors).…”

The pressuring need to reduce the import of fossil fuels as well as the need to dramatically reduce CO 2 emissions in Europe motivated the European Commission (EC) to implement several regulations directed to building owners. Most of these regulations focus on increasing the number of energy efficient buildings, both new and retrofitted, since retrofits play an important role in energy efficiency.

“…There are many possible combinations, and the evaluation of alternatives often involves non-linear objective functions, as shown in [9,10,12]. With the development of computational powers and algorithms, it is possible to address problems that were previously infeasible [11].…”

“…During the design phase of a retrofitting project, MC are also adopted. Energy saving and capital cost are the most considered criteria for optimal building retrofitting planning [9,10]. As the requirements within these criteria are often contradictory, the planning process is essentially a multi-objective optimization problem subject to several constraints.…”

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.
