A building's facade has significant impact on energy consumption. This paper investigates a specific facade configuration based on origami: kaleidocycle rings that can be morphed to enhance daylight uniformity and reduce total energy consumed for heating and cooling. This paper utilizes simulation techniques for identifying the most efficient daylight and thermal performance by incorporating parametric optimization using Grasshopper and Diva-for-Rhino. Analysis was conducted using the Daylight Dynamic Performance Metrics (DDPMs) specifically Spatial Daylight Autonomy (sDA) and Annual Sunlight Exposure (ASE) based on the new IES approved daylight metrics. The simulation was carried out for a south-oriented façade of an office room in Aswan, Egypt, through two phases both used genetic algorithm to drive kaleidocycle parameters. The first phase simulated daylighting for façade optimization which influenced the second phase that run to reach the balance point between daylight and thermal performance. Results LEED V4 daylighting requirements and achieve a remarkable energy saving of 23% in comparison to non-optimized configuration.

Housing is one of the major sectors of national development; it plays a vital role in such a developing country like Egypt. As comfortable home is a human target, housing considers as an important need in human life. Egyptian government deals with middle-income housing as a prototype can be located in any site without considering indoor thermal comfort recommendations. The aim of this paper is to evaluate a present middle-income housing prototype (case study) simultaneously, and improve it by using passive design strategies to reach a sustainable design. The performance of case study evaluated using computer simulation. This research process led to a strategy of improving public housing prototypes in Egypt. The research findings led also to performative design guidelines, achieved sustainability.

Facade design has significant impact on daylight. This paper presents a facade based on origami: kaleidocycle rings that can be morphed enhancing daylight performance in residential spaces, which complies with both LEED V4 and Daylight availability. Daylighting analysis was integrated using Grasshopper, Diva and Genetic optimization for a south-oriented living room facade in Cairo, Egypt, through two phases. First phase dealt with base cases of specific typology. Second phase was conducted using parametric optimization process. Results demonstrate that Kaleidocycle rings of 30 cm size and 64 rotation's angle reached results that exceed LEED v4 requirements while passing Daylight availability standards.

Bricks are significant building elements that are heavily utilized, whether for structural or ornamental purposes. Nevertheless, little has been published on the relationship between brick bonding, shape, and extrusion, and the impact on energy performance. This paper investigates the impact of different brick bond types and projections on building energy using a custom algorithm. This investigation was conducted in two phases on 24 cases for a south façade. The first phase investigated three different brick bonds for their thermal performance: Running, English and Flemish bonds. The second phase involves parametric simulations to evaluate energy consumptions for three extrusion values [baseline " no extrusion " , ¼ brick extrusion, and ½ brick extrusion] and four different extrusion percentages (ranging from 15% to 60%). The first phase results show no significant differences in energy performance for the base case. The second phase results show that the performance achieved was 26% less than the base case. This was accomplished using the Flemish bond with either 30% wall area extruded with half brick length, or 60% bricks extruded with quarter brick length. The preliminary findings indicate a relationship between extrusion and energy performance. Further studies should include in-situ testing and investigation of patterns under different climatic zones.

Parametric approach proved great potentials in generating various alternatives and overcoming traditional scenario-by-scenario limitations, especially when combined with simulation tools. Parallel parametric simulation was suggested as generative-evaluated tool to optimize solar screen driven by daylight and thermal performance in 8 times faster than default runs. This paper proposes an Adaptive-Parametric-Algorithm (APA) for Grasshopper (GH) based on parallel parametric simulation to directly generate optimized alternatives of non-conventional solar screen for specific target performance. APA uses Diva-for-GH to optimize various screen parameters for south-oriented office space in Cairo, Egypt. The results proved APA ability to achieve numerous screens alternatives efficiently that all comply with both LEED-V4 and IES within optimal thermal performance. Moreover, a selection criteria was proposed, that could indicate optimal screen configurations which balance daylight and thermal performance based on daylight simulation only.
