Efficient Shading Device as an Important Part of Daylightophil Architecture; a Designerly Framework of High-Performance Architecture for an Office Building in Tehran

Abstract

(1) Background: considering multiple, and somehow conflicting, design objectives can potentially make achieving a high-performance design a complex task to perform. For instance, shading devices can dramatically affect the building performance in various ways, such as energy consumption and daylight. This paper introduces a novel procedure for designing shading devices as an integral part of daylightophil architecture for office buildings by considering daylight and energy performance as objectives to be optimal. (2) Methods: to address the topic, a three-step research method was used. Firstly, three different window shades (fixed and dynamic) were modeled, one of which was inspired by traditional Iranian structures, as the main options for evaluation. Secondly, each option was evaluated for energy performance and daylight-related variables in critical days throughout the year in terms of climatic conditions and daylight situations (equinoxes and solstices including 20 March, 21 June, 22 September, and 21 December). Finally, to achieve a reliable result, apart from the results of the comparison of three options, all possible options for fixed and dynamic shades were analyzed through a multi-objective optimization to compare fixed and dynamic options and to find the optimal condition for dynamic options at different times of the day. (3) Results: through different stages of analysis, the findings suggest that, firstly, dynamic shading devices are more efficient than fixed shading devices in terms of energy efficiency, occupants’ visual comfort, and efficient use of daylight (roughly 10%). Moreover, through analyzing dynamic shading devices in different seasons and different times of the year, the optimal form of this shading device was determined. The results indicate that considering proper shading devices can have a significant improvement on achieving high-performance architecture in office buildings. This implies good potential for daylightophil architecture, but would require further studies to be confirmed as a principle for designing office buildings.

To Reduce the Annoying Light with Microalgae Window

“…It should be a suitable alternative and adapt to climatic and functional changes in a flexible way, and based on this, the building shell becomes more efficient and dynamic. The research results confirms the current researches by the main pilars of the literature (Talaei M. et al, 2017;Talaei M. et al, 2019;Talaei M. et al, 2021;Talaei M. et al, 2022;Arbab M. et al, 2020;Bazazzadeh H. et al, 2021;Ganji Kheybari A. et al, 2015;Goharian A. et al, 2020;Goharian A. et al, 2021;Pilechiha P. et al, 2020;Saadatjoo P. et al, 2021;Yazhari Kermani A. et al, 2018).…”

Architectural design methods are constantly changing and architects have always sought to introduce design techniques based on information technology, advanced materials and also environmentally friendly, which causes a change in the design process of architects from emphasizing form to function.…”

Green Buildings: Human-Centered and Energy Efficiency Optimization Strategies

“…The calculation for indoor air is used to check the levels of indoor pollutants and compare them to the threshold values. Emission source control strives to design and select low-emission materials for painting, furniture, carpets, and flooring while ventilation aims to provide an appropriate air exchange between indoor and outdoor settings to maintain high IAQ [67].…”

Building Optimisation Vis-À-Vis Solar Shading for Improved Comfort and Energy Efficiency in Classrooms

“…Historical exploration into solar incidences and shading techniques in buildings dates back to 1940 (Dubois, 1997), with different techniques, designs and materials employed by developers in various buildings across different climates worldwide. The design of shading devices is a complex and very challenging task (Bazazzadeh et al, 2021) as it involves a study of the material property of the device itself and the path of the sun's trajectory during different times of the day across the year (Al-Tamimi & Fadzil, 2011). In temperate climates, for example, the sun's altitude varies at divergent angles in a year, calling for care in positioning openings and installing shading devices during these varying periods.…”
