“…Two different approaches are currently adopted for the evaluation of the generated alternatives. The first one, related to said optimization procedures, is based on the maximization or minimization of one or more fitness functions set by the designer and is autonomously carried out by the computer until convergence according to the optimization algorithm [71]. The second method is represented by the design optioneering approach, that allows the exploration of the various design options obtainable from a given set of parameters but without pre-set target values for the outputs of interest [72].…”

In Italy in 2020, only 15.5% of school building heritage was retrofitted from an energy and environmental point of view. In this paper, the cost-optimal method was applied to two different school buildings belonging to the same Italian cold climate zone but characterized by different structural and technological solutions. The research aims at defining the cost-effective redevelopment solution among several ones proposed to apply to this building type. At the same time, this paper provides a critical analysis of the methodology applied, highlighting deficiencies related to a not proper evaluation of environmentally friendly retrofitting measures. In a cost-effective context, the main results show that the intervention on the heating system is more convenient than the retrofitting of the envelope. The energy saving is equal to about 35% for both considered schools. Among the different proposed requalification configurations, the adoption of PV (photovoltaic) electric generation is included. In this regard, an optimization procedure was implemented in a generative design environment to maximize energy production with reference to different design parameters. As a result, a solution with south oriented PV modules with a tilt angle of 42° and arranged in 0.7 m spaced rows proved to be the most effective.

“…Some studies (Tuhus-Dubrow and Krarti, 2010) concern building envelope and the design of glazed elements performing lighting and energy simulations (Hemsath and Bandhosseini, 2015) (Fesanghary et al, 2012) (Wang et al, 2005). However, other researchers (Landim, 2017) highlight the lack of direct control by the designer over operations and parameters, since optimization proceeds until convergence in an autonomous way. Despite this, some authors (Rahmani Asl et al, 2015) still use genetic algorithms in the creation of optimization software based on simulations carried out from BIM models, but performed recurring to external platforms.…”

The research conducted has developed a simulation tool meant to help the designer in the selection of the most appropriate technological solution for building's envelope. The goal was reached combining the parametric nature of Building Information Modeling and computational design techniques. By writing a code in visual programming language (VPL), a design optioneering algorithm has been set up to define and compare several alternative technological solutions and perform technological choices. The method was applied to a horizontal partition towards an unheated space and to an external wall. The optimization, focused on sustainability, constructability and economic issues, led to the implementation of a wood-fibres insulation layer for the slab and a rock-wool one for the façade wall both on the internal and external side. Key Innovations VPL script was designed and written entirely autonomously and therefore no previous and specific reference can be found.  The tool proposed can be applied in the preliminary design stage. Filtering the generated solutions, different and often conflicting aspects can be evaluated in order to satisfy different needs.  While most of the studies in literature focus on the overall analysis of the buildings, the research proposes a specific methodology for the technological components.  The tool created could even be used by designers notexpert in computer technology. Practical ImplicationsIn the definition of the variability ranges for design parameters in the VPL script, the designer must always comply with the legislative minimums for each considered topic. The comparison with further disciplinary aspects (buildability, cost-effectiveness, environmental sustainability) can instead be indicative for the definition of boundary values that cannot be exceeded.

The Italian industrial sector contains 22% of the final energy demand due to the poor energy performance of manufacturing buildings. This proposed study aimed to evaluate retrofit interventions for existing industrial buildings integrating photovoltaic solutions into the external envelope to improve both the environmental sustainability and the facade performance. The methodology is based on an innovative procedure including BIM and generative design tools. Starting from the Revit model of a representative case study, interoperability with energy analysis plugins via Grasshopper were exploited to optimize the differently oriented facade layout of photovoltaic modules to maximize the electricity production. In the case of comparable facade sizes, the building orientation had a minor impact on the results, although a southern exposure was preferable. The optimized configuration involved the installation of PV panels with a tilt angle ranging from −35° to −75°. The best compromise solution between the panel surface area and energy production during the summer solstice involves 466 m2 of PV modules. The design-optioneering approach was used to define possible alternatives to be explored for the possible installation of solar shading systems on existing windows. In this case, the impact on visual comfort within the working environment was chosen as a reference parameter, along with the value of the indoor air temperature. A decrease in this parameter equal to 0.46 was registered for the solution with horizontal (or nearly horizontal) shaders and a spacing ranging between 0.2 and 0.4. The integration of the BIM environment with generative design tools effectively assists decision-making processes for the selection of technological solutions in the building sector.
