“…To design a double active façade [55], we used the model (in combination with Computational Fluid Dynamics (CFD) models) in a co-simulation approach. In the European project MARIE [56][57][58], we used the model to perform a double analysis for the residential typologies in the Mediterranean area, first by optimizing the comfort and economic criteria based on passive measures and, second, by a cost-effective analysis selecting active energy efficiency measures. Other projects where this model has been used include the ACE project described in [59], where the model was used to simulate the behavior of the different typologies that were later implemented in the project.…”

Abstract:The definition of a Life Cycle Assesment (LCA) for a building or an urban area is a complex task due to the inherent complexity of all the elements that must be considered. Furthermore, a multidisciplinary approach is required due to the different sources of knowledge involved in this project. This multidisciplinary approach makes it necessary to use formal language to fully represent the complexity of the used models. In this paper, we explore the use of Specification and Description Language (SDL) to represent the LCA of a building and residential area. We also introduce a tool that uses this idea to implement an optimization and simulation mechanism to define the optimal solution for the sustainability of a specific building or residential.

“…However, the interactions between the Product and Building levels standards are not fully integrated (Paleari et al, 2012), and there is a potential issue to integrate the LCC and LCA seamlessly for assessing refurbishment alternatives due to a lack of interoperability in datasets between the two standards (BRE, 2016). Consequently, researchers have undertaken studies to examine a way to integrate LCA and LCC, and recognised the potential solution in a Building Information Modelling (BIM) system as a data integration complementary platform between LCC and LCA methods (Liu and Issa, 2014;Ortiz et al, 2016). Basbagill et al (2013) and Crawley et al (2008) argue the potential use of BIM to improve current practice of refurbishments because BIM is capable of enhancing collaboration and integration of project information among stakeholders by improving the overall information flow throughout a project life cycle (Eastman et al, 2011;Wong and Fan, 2013).…”

Journal: FacilitiesManuscript ID f-05-2017-0048.R2 Manuscript Type: Original Article AbstractPurpose -The aim of this research is to examine if BIM is feasible as an information management platform to determine a financially and environmentally affordable housing refurbishment solution based on the LCC and LCA calculation.Design/methodology/approach -A case study in conjunction with BIM simulation approach using BIM tools was adopted to identify the feasibility of BIM for the simultaneous formulation of LCC and LCA in housing refurbishment.Findings -This research reveals that BIM is a suitable for the information management platform to enable construction professionals to consider trade-off relationship between LCC and LCA simultaneously, and determine the most financially and environmentally affordable refurbishment solution. The interoperability issues in data exchange among different BIM tools and unstandardized BIM object libraries with incomplete datasets of construction materials are recognized as the major shortcomings in a BIM system. Essential remedial actions to overcome the shortcomings in the current BIM tools are identified. Research limitations/implications -Actual housing information and various refurbishment materialsfor the BIM simulation are limited.Practical implications -This research contribute to supporting construction professionals to prepare practical BIM adoption for the integration of the LCC and LCA that can significantly improve early decision makings on sustainable housing refurbishment.Originality/value -This research will contribute to providing proper remedial actions to overcome the shortcomings in the current BIM tools, and insights for construction professionals to understand the implication of BIM-embedded housing refurbishment.

“…Only deep renovations seem to be the place for further research questions. However, they are intended to provide more detailed economic outcomes such as in [36], where Niemelä et al checked cost-optimal retrofit measures in typical Finnish buildings or in [37], where Ortiz et al designed cost-optimal scenarios for retrofitting residential buildings in Barcelona on global cost evaluation for building lifespan. Assessing the effects of energy retrofitting on flexibility is still missing and is investigated by the authors of the current paper by means of dedicated KPIs.…”

Electrification of the built environment is foreseen as a main driver for energy transition for more effective, electric renewable capacity firming. Direct and on-time use of electricity is the best way to integrate them, but the current energy demand of residential building stock is often mainly fuel-based. Switching from fuel to electric-driven heating systems could play a key role. Yet, it implies modifications in the building stock due to the change in the temperature of the supplied heat by new heat pumps compared to existing boilers and in power demand to the electricity meter. Conventional energy retrofitting scenarios are usually evaluated in terms of cost-effective energy saving, while the effects on the electrification and flexibility are neglected. In this paper, the improvement of the building envelope and the installations of electric-driven space heating and domestic hot water production systems is analyzed for 419 dwellings. The dwellings database was built by means of a survey among the students attending the Faculty of Architecture at Sapienza University of Rome. A set of key performance indicators were selected for energy and environmental performance. The changes in the energy flexibility led to the viable participation of all the dwellings to a demand response programme.
