“…In [29], a new and structured approach was developed to carry out an uncertainty and sensitivity analysis in Life Cycle Assessment (LCA) in order to support the decision-making process in building renovation. Likewise, in [30], a life cycle assessment was used in order to make an economic-environmental valuation of a standard energy retrofit project for a public building in a Mediterranean area.…”

Energy refurbishment of the housing stock is needed in order to reduce energy consumption and meet global climate goals. This is even more necessary for social housing built in Spain in the middle of the last century since its obsolete energy conditions lead to situations of indoor thermal discomfort and energy poverty. The present study carries out a life cycle assessment of the energy and economic performance of roofs after being retrofitted to become cool roofs for the promotion of social housing in Seville (Spain). Dynamic simulations are made in which the time dependent aging effect on the energy performance of the refurbished cool roofs is included for the whole lifespan. The influence of the time dependent aging effect on the results of the life cycle economic analysis is also assessed. A variety of scenarios are considered in order to account for the aging effect in the energy performance of the retrofitted cool roofs and its incidence while considering different energy prices and monetary discount rates on the life cycle assessment. This is made through a dynamic life cycle assessment in order to capture the impact of the aging dynamic behavior correctly. Results point out significant savings in the operational energy. However, important differences are found in the economic savings when the life cycle analysis is carried out since the source of energy and the efficiency of the equipment used for conditioning strongly impact the economic results.

“…The discounted payback period (DPbP) is the number of years it takes to break even from undertaking the investment cost (I 0 ) by discounting future cash flows and recognizing the time value of money (r > 0) [124][125][126][127][128][129][130][131][132][133][134][135][136]; the higher the discount rate, the longer the DPbP. More simply, a payback period (PP) can be calculated without considering the time preference rate (r = 0) [137][138][139].…”

The concept of co-benefits developed in the context of climate change policies can be extended to the strategies aimed at protecting natural resources. A co-effects-based policy approach proposes a multidimensionality capable of strengthening its effectiveness and supporting a co-generative development model aimed at promoting virtuous forms of territorial capital valorisation. The study aimed to evaluate the landscape co-benefits generated by the Natura 2000 networks, achieving a measure of efficiency of the policies and performance of the Management Plan, with reference to the “Timpa di Acireale” site. CVM and TCM were used for the estimation of landscape co-benefits. For the evaluation of the efficiency of the policies and the performance of the Plan, some economic-financial criteria were implemented. With reference to the user-citizen, the local tourist and the supralocal tourist, flows of annual co-benefits of EUR 754,764, EUR 99,678.12 and EUR 2,276.39, respectively, were estimated. The analyses of the efficiency of the policies and the performance of the Plan provided sufficient results. In conclusion, the lack of an adequate level of infrastructure for all users’ profiles reduces the ability to generate co-benefits for the users themselves and more significantly for tourists in a territory with a strong tourism vocation.

“…The above description shows that the UE H index characterizes only the quality of the external envelopes of the buildings, which is influenced, among other things, by the insulation of building partitions, the degree of glazing, the shape of the body, and orientation towards the directions of the world [18,19]. On the other hand, the FE H index represents the quality of the building along with its technical system, so the value of the index depends on the efficiency of heat-generating devices in the building, the amount of heat distribution losses and the efficiency of heat regulation and use, i.e., the quality of technical parameters and solutions in general.…”

“…A literature review finds a dearth of empirical studies that illustrate the correlation between the performed retrofitting and the predicted and measured gas consumption, in particular in the case of performance gap observed in buildings with poor energy standard and reduced conditions of thermal comfort. Although similar studies were previously published, they usually referred to other locations and involved simulation data on the energy performance before and after refurbishment [16,19], included shorter observation periods and limited number of buildings [35,36] or discussed other types of objects [37].…”

Improving the Energy Performance of Public Buildings Equipped with Individual Gas Boilers Due to Thermal Retrofitting

The article assesses an impact of thermal retrofitting on an improvement of the energy quality of public buildings in terms of their heating. The analysis covered a group of 14 buildings, including schools, kindergartens or offices, while energy audits were carried out for 12 of them. The indications of individual gas meters were the source of actual data for the assessment of changes in energy consumption indexes in operating conditions. The analysis showed a clear improvement in the energy quality of buildings; however, the actual effects were much lower than forecasted. The average forecasted decrease in energy consumption was supposed to be 64.3%, but the measured data showed only 37.1%. The investigation confirmed that the most complex refurbishing provided the most satisfactory decrease in energy consumption (51.4% of real decrease in energy consumption), while objects with partial thermal refurbishing reached an efficiency of only 21.8%. It was stated that in operating conditions, special attention should be paid to the manner of energy use, since different indicators of energy consumption can be obtained with the same parameters of building’s balance cover. The results obtained can be further utilized in thermal-refurbishment implementation procedures. Follow-up investigations on the impact of selected parameters on energy consumption are planned.
