“…The results from the real options perspective enabled to conclude that the global cost is not enough for the investors and must be complemented with additional information (as the value of operational flexibility and other strategic factors), and the return of investment must be evaluated in a long-term rather than in the short-term perspective. Other point of view of the same discussion is described by Becchio et al [18]. They introduced the need to incorporate some additional benefits to the global cost calculation, in order to achieve more interesting results for all the actors involved, including investors and final users.…”

“…For instance, Tadeu et al (2016) consider that the global cost indicator is not enough for describing the point of view of an investor and it must be complemented with additional information. Becchio et al (2015) stressed the need to include in the global cost formula other benefits related to energy-design of buildings (as indoor comfort conditions, reduction of CO 2 emissions, embodied energy, real estate market value).…”

Identification of cost-optimal and NZEB refurbishment levels for representative climates and building typologies across Europe

et al. 2017

The energy consumptions of the building stock are playing a central role in the energy policy of the European Union. While the Member States are applying the Directives in force, the European Commission is working to update the regulatory framework. Specifically, it is necessary to achieve the great unrealized potential for energy savings in existing buildings. With this aim, the nearly zero-energy building (NZEB) target was introduced, and a comparative methodology framework to calculate cost-optimal levels of minimum energy performance requirements was proposed. This study focuses on the issue of building renovation, and it presents the results obtained with the application of a cost-optimal calculation method for identifying proper retrofit measures to reach costoptimal levels and NZEB levels. The assessment takes into account an exhaustive set of passive and active renovation options and it was extended to various building types of 60s-70s (residential and non-residential) in a wide range of representative European climatic conditions. A very relevant energy-saving potential was found for all cost-optimal benchmarks, and in many cases, the obtained NZEB refurbishments have resulted interesting also from an economic point of view.

“…The additional economic elements that need to be included in economic assessments were identified by [27]. The economic assessment should also include the monetizable benefits, such as indoor climate quality, derived from each design option [28]. In municipal service buildings, indoor climate quality can be monetized in the life cycle economy through externalities related to increased productivity and reduced employee sick leaves [29].…”

Integrating Energy Efficiency into the Municipal Procurement Process of Buildings—Whose Responsibility?

et al. 2019

View full text Add to dashboard Cite

This study addresses the challenges in ensuring energy efficiency and high indoor climate quality with efficient use of public money in the municipal building procurement process. Energy efficient municipal building procurement provides a significant leverage when steering the built environment towards the low-carbon economy targets of the EU. Municipal building department professionals need more skills and knowledge to appropriately define the requirements and identify the energy efficient design options accounting for the building’s changing operational environment. This study presents how to systematically integrate energy efficiency in the municipal procurement process of buildings by presenting the list of energy efficiency factors to be included into the procurement process. This list of factors clarifies how indoor climate quality, energy use, and the life cycle economy are related through technological solutions and how the optimal compromise solution can be determined. Furthermore, this list of factors explains the responsibilities in integrating energy efficiency within the municipal building procurement process. Applied in the design of the municipal building the list of factors contributes to more informed and transparent decision-making process.
