“…The proposed reverse passive design approach is based on the use of computational design optimization. A similar reverse design approach has been proposed by Luca et al (2021), which focuses on solar envelope buildings. Luca's approach, nevertheless, is developed for a specific type of passive building typologies, which limits its applicability for general passive building design.…”

This paper presents a reverse passive building design approach for sustainable architectural design based on the use of performance-based design optimization. The approach considers building massing and orientation, both of which are of great importance in passive building design, and combines the two factors in a design generation and optimization workflow in Rhino-Grasshopper. A case study based on SDE4 building in Singapore is conducted to demonstrate its capability of providing solutions and information about the tradeoffs and interrelation between building massing and orientation with respect to the consideration of passive cooling and natural daylighting. The result shows that the approach can systematically explore a variety of building massing designs with different orientations and identify high-performing designs that outperform the existing one regarding the two performance objectives. The paper concludes by discussing its relevance in connecting performance-based design optimization research and architecture professionals.

“…Although, there are several building massing methods that take into account the solar access of both, existing and new buildings (Capeluto and Shaviv, 2001;De Luca and Dogan, 2019;De Luca, Dogan and Sepúlveda, 2021). There is a lack of building massing methods based on simultaneously energy performance and solar access of the surrounding buildings that could be used as a negotiation tool by designers without the need of time-consuming energy simulations.…”

“…In practice, due to the non-mandatory nature of daylight standards in most countries, the designer would have flexibility to define a building massing even if the volume of the new building does not guarantee the same SA level for all the surrounding buildings. Indeed, the recently developed method called Reverse Solar Envelope allows the consideration of a certain maximum obstruction index (OI) for each cell of the theoretical block (generated by the extrusion of the buildable plot to a maximum buildable height) (De Luca, Dogan and Sepúlveda, 2021). Moreover, energy performance and solar radiation have been considered as objectives in previous studies developed through focused on multi-objective optimization (Wang, Song and Tang, 2020;Natanian and Wortmann, 2021;Xia and Li, 2021).…”

This paper proposes a novel multi-criteria method for building massing based on energy performance and solar access allowed to the surrounding buildings (Mixed Solar Envelope (MSE) method). We used a single thermal zone simulation-based methodology to validate the method. We applied the MSE method in a generic urban zone located in Tallinn, Estonia. Determining the building form, the designer can prioritize energy performance and/or solar access for each studied neighbor's room, as well as the importance between studied rooms. The method allowed to generate building masses (MSEs) capable of saving up to 73% and 67% of the total annual energy consumption in office and residential rooms with window-to-wall-ratio of 80%. As a tool to negotiate between different rooms, the total annual energy savings was between 56-80% when considering a pure energy-based criterion. The annual energy savings was between 26-30% while maximizing the annual number of sun hours when considering solar accessbased criteria.

“…Sun altitudes and solar azimuth values in annexe tables in EN 17037 are used to filter in only those sun vectors that contribute to direct sunlight for standard compliance. New methods of assessment of solar access and solar envelopes have been proposed recently (de Luca et al, 2021), and are implemented in the plugin the 'Solar Envelope Tools' from Tallinn University of Technology. However, such workflows can only be applied in a defined urban condition for controlling the new building shape.…”

This paper investigates novel computational methods for Regenerative Design by developing further on the European Daylight Standard EN 17037, to make it useful at both urban and architectural scales. Case studies are evaluated for sunlight, daylight and quality views. A computational method, compliant with EN 17037, is introduced for the evaluation of sunlight. An assessment of daylight metrics, for an office building in Helsinki, with a 300 lux target, demonstrates a 12% difference between spatial Daylight Autonomy (sDA; occupied hours) and Illuminance levels (EN 17037 method 2; daylight hours), 37% between sDA and Daylight Factor (EN 17037 method 1), and 25% between methods 1 and 2. A new computational method for evaluating ‘views’ on the floorplan is proposed that considers ‘view content’ (EN 17037 View Out layers), ‘view access’, the potential viewpoint-based ‘outside distance’, and can be extended to add the ‘quality of environmental information’. Further research directions and use of spatial metrics are discussed for sunlight, daylight, and view quality.
