“…Fonsca et al [7] designed a renovation plan for the Department of Electrical and Computer Engineering building in University of Coimbra, Portugal, with the aim to achieve the nearly zero-energy goal using two primary technologies: LED lighting and photovoltaic panels. In contrast, Irulegi et al [8] studied an education building in Spain; the research team proposed different renovation strategies for the winter and summer, and proved that the total energy-saving potential could reach as high as 62%. In this section, several studies with a focus on education building energy renovation and retrofit are briefly reviewed.…”

The aim of this paper is to propose a novel building information model (BIM)–building performance model (BPM)–building environmental model (BEM) framework to identify the most energy-efficient and cost-effective strategies for the renovation of existing education buildings to achieve the nearly zero-energy goal while minimizing the environmental impact. A case building, the University of Maryland’s Architecture Building, was used to demonstrate the validity of the framework and a set of building performance indicators—including energy performance, environmental impacts, and occupant satisfaction—were used to evaluate renovation strategies. Additionally, this novel framework further demonstrated the interoperability among different digital tools and platforms. Lastly, following a detailed analysis and measurements, the case study results highlighted a particular energy profile as well as the retrofit needs of education buildings. Eight different renovation packages were analyzed with the top-ranking package indicating an energy saving of 62%, carbon emissions reduction of 84%, and long-term cost savings of 53%, albeit with a relatively high initial cost. The most preferable package ranked second in all categories, with a moderate initial cost.

“…A universidade pública de Basque Country, na Espanha, é composta de 32 faculdades, divididas em quatro campi, com mais de 40.000 alunos e 7.500 trabalhadores. Nessa instituição, o consumo de energia pelos prédios acadêmicos varia significativamente, oscilando entre 18 e 107kWh/m 2 , e o consumo com aquecimento varia entre 36.8 e 76kWh/m 2 (Irulegi et al 2017).…”

Resumo As universidades, direta ou indiretamente, causam impacto no ambiente através do consumo de água, energia, geração de resíduos e ocupação de áreas verdes. Este estudo teve por objetivo realizar um diagnóstico do consumo de água e energia; geração de resíduos e manejo de áreas verdes no câmpus da Faculdade UnB de Planaltina/Distrito Federal, para propor uma estratégia de gestão sustentável. Para tal, foram analisados os consumos de água e energia (período de 2006 a 2017), a caracterização quali-quantitativa dos resíduos sólidos (2015-2016) e estudo fitossociológico das áreas verdes do câmpus. Os resultados obtidos indicaram que os consumos de água e energia estão aumentando desde a inauguração do câmpus, em 2006, devido à ampliação do quadro de servidores, alunos e áreas edificadas. Dos resíduos sólidos produzidos, 67% são recicláveis. O estudo fitossociológico indicou alta diversidade biológica do Cerrado sentido restrito. Dentre as estratégias indicadas para gestão, indica-se a adoção de programas de uso eficiente da água e de energia elétrica e implantação da coleta seletiva com destinação da fração reciclável a cooperativas de catadores. Nas áreas verdes, recomenda-se sua preservação e conservação, além da expansão do câmpus em áreas mais degradadas do Cerrado sentido restrito, para reduzir a supressão da cobertura vegetal.

“…In [4] and [5] different costefficient retrofit scenarios are discussed for typical educational buildings built around 1960-1970, taking into account occupants' wellbeing. In [6] and [7] two Mediterranean case studies are converted into zero energy buildings while considering IEQ aspects. Ascione et al [8] implement the refurbishment of an ancient university building in Italy by means of model simulation and with the investigation of potential savings.…”

The role of the reference building in the evaluation of energy efficiency measures for large stocks of public buildings

With the last European Directive 2018/844/EU, EU Member States have to outline effective strategies for the energy renovation of existing buildings, so as to achieve the objectives set respectively for 2030, 2040 and 2050, taking advantage of new financing instruments. In this process, public buildings are identified as important drivers for energy-behavioural changes among citizens and, in addition, they can benefit from encouraging mortgages for certified energy efficient renovations. However, the problem of dealing with existing public buildings is their sample size combined with the current necessity of significant renovations. In this scenario, the reference building acquires a key role as the starting model for the evaluation of primary energy needs and of retrofit measures. In this work, a reference building selected by a previous work is further analyzed, testing selected potential retrofit interventions by means of model simulation. The implemented measures are then evaluated using a cost-optimal approach, in order to integrate their priority with respect to cost-effectiveness. The aim of the work is to test on a building centrotype selected retrofit measures, to be then extended to the other buildings similar for their main geometrical and thermophysical features.
