“…Use of natural night cross-ventilation has been considered in the Base + N.V. 50 coded analysis. In this configuration, 50% of the glazed surface in the building was kept open from 00:00 a.m. to 06:00 a.m. according to a specific schedule in order to investigate the effectiveness of night-time natural ventilation [55][56][57].…”

The renewed attention paid to raw earth construction in recent decades is linked to its undoubted sustainability, cost-effectiveness, and low embodied energy. In Italy, the use of raw earth as a construction material is limited by the lack of a technical reference standard and is penalised by the current energy legislation for its massive behaviour. Research experiences, especially transoceanic, on highly performative contemporary buildings made with natural materials show that raw earth can be used, together with different types of reinforcements, to create safe, earthquake-resistant, and thermally efficient buildings. On the basis of experimental data of an innovative fibre-reinforced rammed earth material, energy analyses are developed on a rammed earth building designed for a Mediterranean climate. The paper focuses on the influences that different design solutions, inspired by traditional bioclimatic strategies, and various optimised wall constructions have in the improvement of the energy performance of the abovementioned building. These considerations are furthermore compared with different design criteria aiming at minimising embodied carbon in base material choice, costs, and discomfort hours. Results have shown the effectiveness of using the combination of massive rammed earth walls, night cross ventilation, and overhangs for the reduction of energy demand for space cooling and the improvement of wellbeing. Finally, the parametric analysis of thermal insulation has highlighted the economic, environmental, and thermophysical optimal solutions for the rammed earth envelope.

“…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.

“…This study investigated the energy-environmental effects of the envelope retrofit [9][10][11][12][13], also taking into account economic-financial measurements in three stages: 1) a technical-technological analysis of the hypothesized energy performance improvement by means of the use of sustainable materials, components, and techniques such as wooden double-glazed windows, organic external wall insulation systems, and green roofs; 2) an environmental analysis of this project, developing the life-cycle assessment (LCA) aimed at quantifying the potential impacts on the environment and human health associated with the implementation of the above-mentioned project in order to verify its environmental effectiveness and compliance with the environmental standards [14,15]; and 3) an economic and financial valuation aimed at identifying the cost-effectiveness and the financial sustainability of the project as a whole and in its three parts [16,17]. Due to the complementarity of economic and financial performances, such evaluations involve different areas of decision-making [18][19][20].…”

Energy consumption in public buildings increased drastically over the last decade. Significant policy actions towards the promotion of energy efficiency in the building sector have been developed involving sustainable low-CO2-emission technologies. This paper presents the results of an economic–environmental valuation of a standard energy retrofit project for a public building in a Mediterranean area, integrating a life-cycle assessment (LCA) into the traditional economic–financial evaluation pattern. The study results show that simple retrofit of sustainable low-CO2-emission strategies such as wooden double-glazed windows, organic external wall insulation systems, and green roofs can reduce energy needs for heating and cooling by 58.5% and 33.4%, respectively. Furthermore, the implementation of an LCA highlights that the use of sustainable materials reduces the building’s carbon footprint index by 54.1% after retrofit compared to standard materials, thus providing an additional increase in the socio-environmental–economic–financial results of 18%. Some proposals are made about the accounting of the replacement costs and the residual value as requested in the logic of life-cycle cost (that is the economic extension of the LCA), namely concerning the method to take into account the replacement costs and the residual value. The economic calculation highlights the fundamental role played by tax benefits supporting the building energy retrofit, also in temperate climate zones, thus allowing the creation of environmental benefits in addition to remarkable cost savings.
