The paper addresses an important long-standing question in regards to the energy efficiency renovation of existing buildings, in this case hotels, towards nearly zero-energy (nZEBs) status. The renovation of existing hotels to achieve a nearly zero-energy (nZEBs) performance is one of the forefront goals of EU’s energy policy for 2050. The achievement of nZEBs target for hotels is necessary not only to comply with changing regulations and legislations, but also to foster competitiveness to secure new funding. Indeed, the nZEB hotel status allows for the reduction of operating costs and the increase of energy security, meeting the market and guests’ expectations. Actually, there is not a set national value of nZEBs for hotels to be attained, despite the fact that hotels are among the most energy-intensive buildings. This paper presents the case study of the energy retrofit of an existing historical hotel located in southern Italy (Syracuse) in order to achieve nZEBs status. Starting from the energy audit, the paper proposes a step-by-step approach to nZEBs performance, with a perspective on the costs, in order to identify the most effective energy solutions. Such an approach allows useful insights regarding energy and economic–financial strategies for achieving nZEBs standards to highlighted. Moreover, the results of this paper provide, to stakeholders, useful information for quantifying the technical convenience and economic profitability to reach an nZEBs target in order to prevent the expenses necessary by future energy retrofit programs.

Seismic Vulnerability and Old Towns. A Cost-Based Programming Model

et al. 2019

Vulnerability is a big issue for small inland urban centres, which are exposed to the risk of depopulation. In the climate of the centre-northern part of Italy, and in the context of the recent concentration of a high number of earthquakes in that area, seismic vulnerability can become the determinant cause of the final abandonment of a small town. In some Italian regions, as well as in Emilia Romagna, municipalities are implementing seismic vulnerability reduction policies based on the Emergency Limit Condition, which has become a basic point of reference for ordinary land planning. This study proposes an approach to seismic vulnerability reduction based on valuation planning for implementation within the general planning framework of the Faentina Union, a group of five small towns located in the southwestern part of the Province of Ravenna, Italy. This approach consists of three main stages: knowledge—the typological, constructive, and technological descriptions of the buildings, specifically concerning their degree of vulnerability; interpretation—analysis with the aim of outlining a range of hypotheses with respect to damage in case of a prospective earthquake; and planning—the identification of the courses of action intended to meaningfully reduce the vulnerability of buildings. This stage includes a cost modelling tool aimed at defining the trade-off between the extension and the intensity of the vulnerability reduction works, given the budget.

“…(1) The net present value (NPV) is the sum of the incoming and outgoing cash flows, that is, revenues (R) and costs (C), over a defined time horizon (T), discounted at the discount rate r. NPV is less, equal or more than the (net) future value (FV) if the discount rate (r) [130][131][132][133] is more, equal or less than 0; NPV is expected to be significantly positive in case of a private player (Equation ( 3)):…”

“…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.
