“…Consequently, they show high heat losses and poor energy performance throughout the year [50]. Hence, one way to increase their performance may consist in the improvement of the roof, either by increasing the insulation thickness or through the application of innovative solutions, such as cool and green roofs.…”

Abstract:The recast of the energy performance of buildings directive (EPBD) describes a comparative methodological framework to promote energy efficiency and establish minimum energy performance requirements in buildings at the lowest costs. The aim of the cost-optimal methodology is to foster the achievement of nearly zero energy buildings (nZEBs), the new target for all new buildings by 2020, characterized by a high performance with a low energy requirement almost covered by renewable sources. The paper presents the results of the application of the cost-optimal methodology in two existing buildings located in the Mediterranean area. These buildings are a kindergarten and a nursery school that differ in construction period, materials and systems. Several combinations of measures have been applied to derive cost-effective efficient solutions for retrofitting. The cost-optimal level has been identified for each building and the best performing solutions have been selected considering both a financial and a macroeconomic analysis. The results illustrate the suitability of the methodology to assess cost-optimality and energy efficiency in school building refurbishment. The research shows the variants providing the most cost-effective balance between costs and energy saving. The cost-optimal solution reduces primary energy consumption by 85% and gas emissions by 82%-83% in each reference building.

“…Moreover, many standards should be reconsidered if urban climate is different than the supposed one. Researches conducted in other world regions tend to confirm the poor summer performance of buildings that should have a near-zero energy performance in theory [23]. In this sense, mitigation strategies should be re-developed as "adaptigation" strategies [24], that is, mitigation strategies for a scenario adapted to the UHI and other anthropogenic impacts on the environment.…”

Abstract. The urban heat island (UHI) effect is constantly increasing the energy consumption of buildings, especially in summer periods. The energy gap between the estimated energy performance -often simulated without considering UHI -and the real operational consumption is especially relevant for institutional buildings, where the cooling needs are in general higher than in other kind of buildings, due to more internal gains (people, appliances) and different architectural design (more transparent façades and light walls). This paper presents a calculation of the energy penalty due to UHI in two institutional buildings in Rome. Urban Weather Generator (UWG) is used to generate a modified weather file, taking into account the UHI phenomenon. Then, two building performance simulations are done for each case: the first simulation uses a standard weather file and the second uses the modified one. Results shows how is it necessary to re-develop mitigation strategies and a new energy retrofit approach, in order to include urbanization ad UHI effect, especially in this kind of buildings, characterized by very poor conditions of comfort during summer, taking into account users and occupant-driven demand. IntroductionInstitutional buildings like: offices, universities, schools, hospitals, etcetera, constitute a very important part of the building stock. In Italy, Many of these buildings were built in the XIX and in the first half of the XX Century, without specific measures to reduce energy consumption. As a result, the institutional buildings are responsible of almost the 20% of the total building stock energy demand in the country (REF IS NEEDED). Moreover, the consumption profile of institutional buildings is different from the residential buildings stock: in 2008 institutional buildings consumed more electricity than residential buildings (39% versus 22% of the total consumption) due to more intensive use of air conditioning (19% versus 1%), appliances and lighting (9% versus 3%) [1]. Italy has today a good share of renewable energy contribution to electricity production (about 40%). However, the high demand of electricity that institutional buildings have poses a challenge for energy demand and urban sustainability.
