“…These interventions are also often combined with the installation of photovoltaic solar panels at the service of common and private parts, ensuring even higher energy performance. Table 3 shows the summary of the macro-categories and categories of intervention [59]. Table 4 shows the amounts of each macro-category of work (which include the respective share of the safety costs) and the summary from the project's economic framework.…”

This paper explores the topic of the energy transition in housing. The work aims to offer a knowledge base for energy policy on the current scenario of the energy redevelopment of Italian multi-family buildings. The financial feasibility of energy retrofit projects in the case of multi-apartment buildings is then analyzed. From a set of projects located in the Campania region (Italy), the typical building on which to carry out ordinary energy efficiency works was identified. Two design variants are considered on which to implement the Cost-Revenue Analysis (CRA): (i) energy retrofit intervention not including photovoltaic system; (ii) energy retrofit intervention including photovoltaic system. For the second design variant, further analyses were conducted (sensitivity analysis, scenario analysis, risk analysis) to identify the main sensitive variables and to estimate the probability of financial failure of the intervention. The study shows that interventions without photovoltaics are unlikely to be financially sustainable. However, although the presence of photovoltaics significantly increases the savings in the bill, the Payback Period (PP) remains quite high. An ordinary energy retrofit project including photovoltaic technology can be made financially sustainable only by resorting to government building bonuses, in the absence of which the probability of failure is 46%.

The paper explores the theme of sponsorship aimed at enhancing the historical-architectural heritage, analyzing the point of view of companies. Specifically, a static analysis model proposed in a previous paper, whose objective is to establish the optimal amount to invest in sponsorship to maximize business profit, is integrated with an innovative model that allows the company to assess the degree of financial efficiency of the investment, i.e. its productivity . The latter depends on a series of variables that characterize both the monument to be enhanced, the location in which it is located, and the sponsorship strategy adopted by the company. However, in the case of sponsorship of recovery/restoration work, the critical variable that most affects the efficiency of the investment is the number of visitors to the location where the monument is located (direct audience). This is because as the number of visitors increases, the level of exposure to the sponsorship message increases. Therefore, we assume two functional relationships, one linear and the other logarithmic, which correlate financial efficiency to the average number of visitors. In this way, the advantage of the company is twofold. On the one hand, it has the opportunity to maximize profits by investing the optimal amount of sponsorship. On the other hand, it can choose the level of productivity of the investment by deciding to finance the monument of a specific location according to its degree of exposure.

“…Some studies focused on the unit sale price of vacant, unimproved land parcels, comparing them with RE market prices in the same areas [32][33][34][35]. Meanwhile, other studies, similar to the current work's aims, estimated the land value by applying the residual land value method as a residual by subtracting the development cost from the sale price of the developed property [4,26,27,[36][37][38][39][40].…”

Urban Density and Land Leverage: Market Value Breakdown for Energy-Efficient Assets

A real estate asset comprises land and improvements. The proportions of these components vary over time and across locations. Notably, the land value component is consistent over time, unaffected by depreciation. Consequently, the weight of land value in determining the overall asset value is crucial, particularly in those improvements that are highly sensitive to depreciation, such as energy-efficient buildings. While several studies have explored the relationship between energy-efficient building consumption and urban density, there is currently a research gap concerning the relationship between land value and the value of efficient improvements built on it. Before investigating this potential relationship, it is imperative to preliminary examine any possible correlations between land values and land density. To verify this correlation, we captured the “Land Leverage” of a real estate property by calculating the ratio between the value of the land and the total value of the real estate property and correlating it with the allowable density. Our analysis of the Land Leverage (LL) trend in a restricted development area over a ten-year period demonstrates that LL increases with the level of permitted density in a neighborhood. This evidence will serve as the foundation to verify whether Land leverage, through urban-densification strategies, might be a pivotal factor in driving the values of energy-efficient assets.
