Building sustainability, in term of energy efficiency, low-impact building materials, renewable energy, has experienced significant growth during the past years. In response to the growing dependence on fossil fuels and importations, due in part to the increase of energy consumption in the residential sector (in 2009 46,9 Mtep, 3% more than 2008) and the recent European directives (i.e. EU 2009/28/CE) requiring CO2 emissions cut of up to 13% in 2020, there is interest in promoting energy efficiency and renewable energy technologies, which are suitable for residential applications. In this paper we present an overview on actions related to minimization of buildings energy consumption in Italy. Prevalent line of action is to improve the energy performances of building envelope (Dlgs 192/05) using insulated frames, walls and roofs and replacing heat generators with condensing boilers. In addition to national directives, ONRE Report 2011 (National Observatory on building regulations) shows that 831 Municipalities (10% more than 2010) establish mandatory targets for insulation, photovoltaic solar panels, solar water heaters, heat pumps use, correct buildings orientation, saving of water resource and local materials use. In addiction an efficient energy rating of the buildings could promote the spread of energy efficiency measurement and consequently facilitate their implementation. The new energy rating system should meet international standards, regarding environment and energy aspects, and respect territorial needs.

University Training

Energy efficiency in buildings is one of the main challenges in EU policy, since it is difficult to find common strategies and policies among Member States.  This article describes the USE Efficiency project, an initiative to create a common training framework for energy efficiency systems in buildings based on the Energy Performance Building Directive (EPBD), through university actions. Universities and students are proposed as shining examples both for energy efficiency solutions and for energy efficiency behaviour.  Moreover, involving university students guarantees acting on closest future market players and most convincing actor in diffusion of public opinions. The project aims to improve energy efficiency in university buildings and to establish training program for students around European countries.  In fact, this activity involves 9 Universities (Technology Faculties and Faculties of Engineering) and 4 technological and market players from widespread countries in EU.Initially, a mapping of the methodologies used for evaluating energy efficiency at the different countries is carried out. Students are trained in energy efficiency methods and strategies, having real work experience implementing these Energy Performance Assessment (EPA) methodologies in their own buildings. The wide geographical coverage of the consortium allows an important crossover of methodologies to achieve technical results even to a professional and technological level. Then, the analysed buildings at each university are monitored in order to collect data, which are then used to plan solutions to improve energy performance of the university buildings. This paper describes this innovative training initiative, which involves students as main actors, working and interacting together with professors and technicians in order to improve energy efficiency in their educational centres.

Buildings with architectural constraints and recognized historical values require a careful design process, aiming to combine the needs of conservation and the adaptation of the buildings to the modern use and its accessibility. The feasible interventions consist in improving the energy performance of the building envelope, in inserting efficient technological systems and using renewable energy sources where possible. The compatibility between the architectural constraints of the building and its more sustainable future use represents a crucial challenge. This work presents the interventions designed and realized on a small villa located in the Prati district, in Rome. Starting from the requests of the client, the primary objective was to create a comfortable house both in the winter and in the summer season, with widespread use of automation systems for managing the utilities. In line with the current energy scenario, the interventions were oriented to energy efficiency, the reduction of polluting emissions, the electrification of utilities and the use of renewable energy sources. The proposed solutions showed high gains in terms of energy saving even if the changes to the building envelope were limited by the desire to preserve the values of the cultural heritage. Therefore, a virtuous refurbishment can effectively respond to current energy efficiency goals.

Purpose The purpose of this study was to design a renovation plan for a university campus building (Department of Electrical and Computer Engineering) with the aim to achieve nearly zero energy performance, ensuring a low specific demand (lower than 44 kWh/m2) and a high level of on-site renewable generation (equivalent to more than 20 per cent of the energy demand). Design/methodology/approach The baseline demand was characterized based on energy audits, on smart metering data and on the existing building management system data, showing a recent reduction of the electricity demand owing to some implemented measures. The renovation plan was then designed with two main measures, the total replacement of the actual lighting by LEDs and the installation of a photovoltaic system (PV) with 78.8 kWp coupled with an energy storage system with 100 kWh of lithium-ion batteries. Findings The designed renovation achieved energy savings of 20 per cent, with 27.5 per cent of the consumed energy supplied by the PV system. This will ensure a reduction of the specific energy of the building to only 30 kWh/m2, with 42.4 per cent savings on the net-energy demand. Practical implications The designed renovation proves that it is possible to achieve nearly zero energy goals with cost-effective solutions, presenting the lighting renovation and the solar PV generation system a payback of 2.3 and 6.9 years, respectively. Originality/value This study innovated by defining ambitious goals to achieve nearly zero energy levels and presenting a design based on a comprehensive lighting retrofit and PV generation, whereas other studies are mostly based on envelope refurbishment and behaviour changes.

Sustainability has been increasingly incorporated as an essential life perspective into educational institutions as well as local communities. Universities play an important role into the society by debating theoretical contributions and implementing concrete actions. The present research was developed to evaluate a university’s energy efficiency by using the Polytechnic University of Catalonia, Spain as a reference for University of Passo Fundo, Brazil. The reference values and index ratings obtained for energy performance, in the Universities’ building stock, were evaluated based on positive and negative features. The study identifies and assesses the evolution of incident factors towards energy consumption and its impacts on the hidropower generation, the main energy resource in Brazilian. Hence, the university can promote a reflection about its practices to develop feasible tools that contribute to sustainable measures. As a result, guidelines and strategies were proposed, not only on targeted evaluated buildings but also on the entire building stock. The research indicates the importance to follow well-defined guidelines in the decision-making process by institutions of higher education, in order to consider integrated sustainable practices. The methodology and findings contribute to improve and promote Education for Sustainability, which should encourage other similar universities to put sustainable projects into practice and encourage the whole society to face the inevitable change of paradigms for achieving the Sustainable Development Goals (SDGs).
