“…Overall energy consumption, largely founded on non-renewable energy sources, became threatening for the environment, thus global focus on reduction of non-renewable energy consumption increased [1,2]. Necessity to reduce fossil fuel consumption and CO 2 emissions led energy-efficient improvements of existing buildings and regulations for new building designs.…”

a b s t r a c tEnergy-efficient retrofits include improvement of building envelope via insulation, employment of building integrated renewable energy technologies, and climate control strategies. Building envelope improvements with insulation is a common approach, yet decision-making plays an important role in determining the most appropriate envelope retrofit strategy. In this study, main objective is to evaluate and optimize envelope retrofit strategies through a calibrated simulation approach. Based on an energy performance audit and monitoring, an existing building is evaluated on performance levels and improvement potentials with basic energy conservation measures (ECMs). The existing building is monitored for a full year and monitoring data is used in calibrating the simulation model. In order to obtain a better-performing building envelope three retrofit strategies including several ECMs are proposed. Retrofit strategies are simulated through calibrated base-case model, and results are evaluated according to changes in indoor environmental parameters and annual energy consumption measures. The analysis of results indicated that pre-assessed strategies yield close results. Therefore, a more comprehensive evaluation based on different decisive criteria is used in optimization of the final retrofit strategy, with the intention to evaluate the effect of individual ECMs on annual end-use energy consumption and investment.

“…Because the lands are state owned but many buildings are private properties, land acquisition and residential relocation are always the most difficult issues to resolve [63]. For the rehabilitation, most efforts have been done to improve technology or management in the building scales, especially energy efficiency retrofitting [64,65]. There is a disparity of interests and expectations between affected residents in redevelopment and rehabilitation due to their fundamental differences in approaches and outcomes.…”

China's fast growth of economy and urbanization have driven large-scale urban renewal projects, thus triggering a wide spectrum of unsustainable problems. Little research has systematically explored the stakeholders' expectations in urban renewal projects in China. A deeper understanding of the divergent interests and expectations of the key stakeholder groups is an important step towards sustainable urban renewal. This paper aims to analyze the stakeholders' expectations on urban renewal projects. Eighteen factors are identified and compared among the main stakeholders: government sectors, consulting parties, the general public and affected residents in both redevelopment and rehabilitation projects, using questionnaire survey and interviews in Chongqing, China. The results reveal that there exist enormous differences of opinions and interests among stakeholders in all economic, environmental and social aspects. To achieve sustainable urban renewal in China, the governments ought to reconsider what the "public interest" stands for. In-situ residents should be understood and treated differently, based on the type of projects. An effective dialogue mechanism as well as supportive administrative and legal system should be established. Moreover, urban-renewal-related education and publicity should be a long-term strategy to change current awareness of different stakeholders, by improving their skill and willingness to participate.

“…Tuning parameters is unfeasible in actual case studies since one optimization process can take days to complete. The other approach based on hybrid optimization algorithms, try to narrow down the search space and utilize fast and accurate gradient-based search algorithms to converge on the optimal region ( [10], [11]). …”

Nowadays municipalities are facing an increasing commitment regarding the energy and environmental performance of cities and districts. The multiple factors that characterize a district scenario, such as: refurbishment strategies' selection, combination of passive, active and control measures, the surface to be refurbished and the generation systems to be substituted will highly influence the final impacts of the refurbishment solution. In order to answer this increasing demand and consider all above-mentioned district factors, municipalities need optimisation methods supporting the decision making process at district level scale when defining cost-effective refurbishment scenarios. Furthermore, the optimisation process should enable the evaluation of feasible solutions at district scale taking into account that each district and building has specific boundaries and barriers. Considering these needs, this paper presents a multi-objective approach allowing a simultaneous environmental and economic assessment of refurbishment scenarios at district scale. With the aim at demonstrating the effectiveness of the proposed approach, a real scenario of Gros district in the city of Donostia-San Sebastian (North of Spain) is presented. After analysing the baseline scenario in terms of energy performance, environmental and economic impacts, the multi-objective Harmony Search algorithm has been employed to assess the goal of reducing the environmental impacts in terms of Global Warming Potential (GWP) and minimizing the investment cost obtaining the best ranking of economic and environmental refurbishment scenarios for the Gros district.
