“…In Becchio et al [24], two refurbishment options (implying high and low investment costs, based on different thermal performances, original or new use category and conditioned volume) for a traditional rural building located in Livorno Ferraris (a small town in Northern Italy) were analysed. Both scenarios foresee the insulation of the external walls and roof, the realization of insulated and ventilated floor over the ground, and the replacement of windows with new ones having different performances based on different targets.…”

“…Under the Heating, Ventilation and Air Conditioning (HVAC) systems point of view, many studies have investigated different solutions. For instance, in Becchio et al [24] different alternatives of refurbishment were evaluated considering architectural heritage, energy efficiency and costs (low/high investment). A condensing boiler for space heating and a multi-split system for space cooling were assessed in the low investment scenario, which foresees a residential use, while a water-to-water Heat Pump (HP) and mechanical ventilation system in the high investment scenario, which foresees a touristic use.…”

This research is framed in the development of an agri-food hub in the city of Milan, including retrofitting an historical farmhouse. In particular, it focuses on the renovation of two historical buildings within the farmhouse. It aims to present a method to support the energy retrofit design of protected buildings, assuming the possibility of achieving high energy efficiency and integration of local renewable sources, while respecting the constraints related to the building's historical value. Two envelope scenarios, with internal and external insulation, were developed, simulated with Integrated Environmental Solutions: Virtual Environment tool and evaluated. As main results, for the demand side there are no significant differences in terms of energy loads on yearly basis in the two retrofit scenarios, on the supply side, several aspects were considered, including the local renewable potential. Concluding, the application of the described method to the mentioned case study can support in tackling the challenges of protected buildings energy retrofit.

“…Moreover, the number of scientific publications in this field increased dramatically in the last years (Martínez-Molina et al ., 2016). In fact, despite the first studies regarding historical buildings’ energy performances implementing new non-destructive technologies were conducted since the beginning of XXI Century, after the global economic crises in 2007, the number of publications has grown, especially those adopting an economic point of view (Costanzo et al ., 2006; Becchio et al , 2017). Currently, heritage preservation and energy efficiency are still often conceived as mutually exclusive purposes, because the enhancement of energy performances involves some actions on the building fabric that could damage the monumental value and the static stability of historical buildings (Ragni et al ., 2013).…”

Purpose Today, about 30 per cent of European existing buildings can be entitled as “historical buildings”. Nowadays, their energy retrofit is important to reach the ambitious European CO2 emissions’ reduction objectives. The purpose of this paper is to outline a methodology to investigate the potential energy savings and the enhancement of historical buildings’ liveability by acting only on their operation, so that the building fabric could be maintained as much as possible as the original evidence. Design/methodology/approach The paper describes the framework’s theoretical phases and their application in two real case studies. The methodology was conceived with a pre-test and post-test design approach. Findings The research demonstrated that the elaborated methodology is flexible and allows the adoption of different energy retrofit strategies for the different cases. Research limitations/implications Limitations arise out of the circumstance that the methodology is based on occupants and technicians willingness to engage in the strategies, so it is not possible to quantify its efficacy ex ante. Practical implications Practical implications can be found in the way of addressing energy retrofit strategies through a user-centric approach with minimum impact on the building itself. Social implications At the same time, the methodology has a strong social aspect with its potential to change people’s attitudes towards energy usage and behaviour. Originality/value This study not only represents the first attempt of applying a systematic energy retrofit strategy based on occupants and technicians behavioural change in historic buildings, but also is one of the first studies dedicated to occupants’ comfort and behaviour assessment in this context.

“…Overall, despite numerous studies conducted on education buildings, information on the energy consumption of this building type is still limited, in comparison to other commercial and residential buildings [3,[9][10][11][12][13][14][15]. Furthermore, most reports focus on primary and secondary school buildings, with very limited studies concentrated on higher education buildings.…”

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.
