Опубликована: Июнь 1, 2024

This work investigates the influence of building form, natural ventilation, and window shading passive strategies on thermal performance comfort three residential forms, namely rectangular, L-shape, U-shape, in hot-dry summer Amman, Jordan. The buildings is studied using indoor air temperature, evaluated according to ASHRAE-55 Fanger's models. buildings' models are designed SketchUp plugin OpenStudio then plugged into EnergyPlus simulator. It obtained that when ventilation devices considered together, temperature notably dropped up 8.85 °C daytime 12.70 at nighttime, which improves all forms. Generally, rectangular exhibits best behavior under optimum conditions. U-shape presents for primary conditions, it records lowest out-of-comfort percentage time during day achieves highest comfortable after considering window's area control.

Impact of Window Design on Dynamic Daylight Performance in an Office Building in Iran

Journal of Daylighting, Год журнала: 2023, Номер 10(1), С. 31 - 44

Опубликована: Март 22, 2023

Window design affects the building's appearance. Besides, it has a significant impact on daylight performance and visual comfort of interior spaces. Therefore, choosing shape position windows can be challenge for architects. This research aims to investigate window dynamic enhance comfort. The examines five common shapes that are located in two different positions southern-facing side. most metrics LEED v4.1 were used spatial autonomy (sDA), annual sunlight exposure (ASE). Furthermore, useful illuminance (UDI) was considered complementary approach assess levels. examined three cities including Mashhad, Isfahan, Bandar Abbas, which northeast, center, south Iran, respectively. Thirty simulations each city conducted by Grasshopper Graphical editor as parametric interface its plugins, ladybug, honeybee analysis. results emphasize performance. square meets needs achieving maximum sDA minimum ASE up 68.8% 20% both positions, Moreover, centrally positioned presents lowest level 14.4% among other cases. However, higher position, especially horizontal obtain highest values sDA, UDI, 77%, 59%, 30%, rates deteriorate increasing sill height head windows. paper provide recommendations based comparison shapes.

Energy is a significant part of socio-economic development modern societies. Increasing fossil fuel consumption almost the main source energy throughout world. Thus, it essential to search for more sustainable alternatives or method decrease this huge amount usage. On other hand, building industry known as one biggest consumers. Among efficiency measures, openings are playing key role in declining consumption, especially hot summers Cyprus. Therefore, study carries out field measurement various opening sizes case order make satisfactory situation both from and visual comfort considerations. Meanwhile, studio faculty architecture, Famagusta, North Cyprus, has been selected an experimental examination show effectiveness method. In analyze its performance, calculation simplified chosen. Outcomes intended illustrate benefits authorize size comparisons display differences conservation measures inherent compliance methods allowable by regulations. Finally, results obviously that decreasing window-to-wall ratio, heat loss significantly reduces. But, considering daylight factor (DF) standard defined range applying 750lux lighting requirement studio, finding minimum WWR seems meaningful. according mentioned criteria special case, optimum can be considered 10 20%, which gives architects some flexibility apply their designs.

A Generative Design Approach to Improving the Environmental Performance of Educational Buildings in Hot Arid Climates. (Assiut National University as a Case Study)

Future Cities and Environment, Год журнала: 2024, Номер 10, С. 2 - 2

Опубликована: Фев. 22, 2024

The architectural design process is complex, involving diverse objectives that may be contradictory, and on which orientation exerts significant influence. artificial intelligence application, Generative Design facilitates solving multi-objective dilemmas through the creation evaluation of numerous alternatives. However, its exploration in educational buildings hot arid climates remains limited. Given impact spaces’ function distribution, this study aims to optimize it typical plans buildings. Employing a approach enhance environmental performance. conducted evaluated national universities Egypt as case study, specifically Assiut City. results revealed optimum for certain objective has not equated optimal performance other goals, highlighting an inherent contradiction between them. Among 26,334 possible alternatives difference scenario least favourable one parameters related spaces: natural daylighting, visual comfort, ranging from 10% 24%, besides around 1% whole building, including energy consumption, thermal carbon emission. This research offers framework applicable various building types. Additionally, encourages decision-makers adopt no-cost sustainable approach.

OPTIMIZATION OF VISUAL COMFORT IN OFFICE SPACE BASED ON STOCHASTIC SHADE ADJUSTMENT

Journal of Green Building, Год журнала: 2024, Номер 19(1), С. 157 - 176

Опубликована: Фев. 22, 2024

ABSTRACT The visual comfort of building occupants may be directly affected by stochastic modulation shading. In this paper, simulations combined with statistical analysis were used to investigate and evaluate the different seating positions in an office. dynamic daylighting indicators (UDI, DGP, sDA, ASE) analyze within main findings show following: (1) DGP ASE metrics that probability glare near windows is not always highest. influence line-of-sight direction should also considered. (2) By running 50 simulations, average value sDA300/50% was 0.97, ASE1000/250 11.4%. This shows office has good quality. (3) optimal determined based on four indicators, alternative options for indoor occupant preferences provided. research results paper aim provide references improvement occupants.

Assessment of the discrepancy between daylight factor and using illuminance data methods by climate zones under EN:17037

Advances in Civil and Architectural Engineering, Год журнала: 2024, Номер 15(28), С. 133 - 150

Опубликована: Май 20, 2024

Conducting a rigorous evaluation of the daylight performance buildings is essential for human health and energy efficiency. Today, there are two main methods used analysis: factor, which has been since early 1900s, newer approach known as climate-based modelling. Both employed in EN 17037 Daylight Buildings’ standard. Utilizing different calculation causes discrepancies provision analyses room. However, no definition or limitation this subject As result, researchers prefer same location daylighting without clear justification. Additionally, lack parametric that follow guidelines This study aims to analyse impact on according regions generate compliance with In respect, comparison calculations conducted theoretical room situated all 81 provinces Turkey, where variant climate types occur over year. Furthermore, workflows generated using Rhinoceros/Grasshopper following directives The findings indicate method choice affects illumination levels zones, ranging from 15 114 %.
