A Model for the Assessment of the Economic Benefits Associated with Energy Retrofit Interventions: An Application to Existing Buildings in the Italian Territory

Abstract

In recent decades, the issue of existing buildings’ energy retrofit has played a central role in the context of international and national territorial development policies, mainly due to the obsolescence state that characterizes the housing stock. Since the current need for energy renovation collides with the widespread low spending capacity of the owners, in recent years numerous fiscal incentives have been envisaged, aimed at promoting building initiatives for the improvement of energy performance indices. With reference to the Italian fiscal measure so-called Superbonus, introduced by the “Relaunch” Law Decree No. 34/2020, in the present research, a model for evaluating the economic benefits, in terms of the convenience of the operators involved, generated by energy requalification interventions, has been proposed. The analysis has been developed with regards to the Italian territory and to the prevailing building typology, by considering 110 provincial capitals and the main urban areas into which each city is divided (central, semi-central, and peripheral). Specifically, for each urban area of the Italian capitals considered, the market value differential between the after energy and before energy intervention situations has been firstly determined. Furthermore, assuming an ordinary profit margin of a generic investor interested in this type of investment, the break-even incentive, i.e., the percentage threshold able to ensure the condition of minimum convenience for an investor, has been estimated for each urban area.

A Knowledge and Evaluation Model to Support the Conservation of Abandoned Historical Centres in Inner Areas

“…For the cost-benefit analysis, classes of costs and benefits/revenues and their properties can be defined [152][153][154][155][156][157]. A new system of relationships may involve the new classes together with the original classes and properties, leading to queries aimed at verifying economic feasibility.…”

What Is the Impact of the Energy Class on Market Value Assessments of Residential Buildings? An Analysis throughout Northern Italy Based on Extensive Data Mining and Artificial Intelligence

“…Indeed, new laws and regulations may decisively change the willingness to remunerate specific characteristics of the buildings. Energy performance is a factor that is becoming increasingly more important and more appreciated in property valuation [21]. A high energy performance is not only an opportunity to save money on future energy consumption from a life-cycle perspective but also an essential contribution to reducing the impact of pollutant emissions.…”

Incentive initiatives on energy-efficient renovation of existing buildings towards carbon–neutral blueprints in China: Advancements, challenges and prospects

“…Ho et al [20] adopted the systematic literature review and focus group sessions to select key performance indicators such as payback period to further develop a performance assessment system for commercial building renovation; ii) In terms of incentives for building energy-efficient renovation, Amoruso et al [21] analyzed the weaknesses of current regulations in Korea to support building energy-efficient renovation through exemplary scenarios corresponding to typical building types, and further quantified the calculation methods and criteria for financial incentives regarding building height, area, and energy efficiency technologies. Tajani et al [22] assessed the impacts of existing financial incentives for energy-efficient renovation of buildings in Italy on the economic benefits for the operators involved by creating Geographical Maps of Economic Benefits and Convenience Maps, and estimated the minimum subsidies for investors under different climatic conditions and building technologies; iii) In terms of owner/enterprise participation in building energy-efficient renovation, Ma et al [23] derived three main elements for homeowner participation in the processes of building energy-efficient renovation through semi-structured interviews and questionnaires, including the procedures, the composition of the working group, and the discussed contents, and suggested the establishment of a homeowners' association to be a communication channel between homeowners and the working group. Wade et al [24] conducted an investigation based on interview data from partner firms for building energy-efficient renovation and suggested that policy makers developed shared databases to guide the allocation of resources and responsibilities between local governments and delivery enterprises.…”
