Multi-Objective Approach For Optimizing Buildings’ Forms And Kinetic Façades Systems In Office Buildings, Randa Mohamed Ahmed Mahmoud

Mansoura Engineering Journal

Due to the critical reliance of office buildings on wide-glazed areas for providing daylight which increases heat gain, the kinetic façades (KF) have been innovated to improve buildings’ envelopes. This study proposed a parametric computational methodology to optimize building forms and the KF system of office buildings cooperatively. The computational methodology was implemented by using Rhinoceros software and consists of 4 phases. The main aim is to improve the annual energy consumption, average daylight factor, and payback period, and the results concluded a significant improvement after applying the KF system by 1050.3 kWh/m2, 17.34%, and 6.8 years, respectively. Building parameters …

Sustainable Urban Development Approach In Residential Building, Ayah Mohamed Ramadhan, Ahmed Noor Eldin

Mansoura Engineering Journal

Globally, Due to its damaging effects on energy, consumption, health, wellbeing, and air pollution, the urban warming phenomenon is gaining worldwide awareness from scientists to planners and legislators. In order to achieve the equation and reach an energy-saving urbanization, we must reconcile with the environment by providing a sustainable urban design that works to rationalize energy and reduce the depletion of resources and reach a sustainable urban environment by providing thermal comfort requirements. In order to attain three key characteristics that are related to one another—thermal comfort, reduced energy consumption, and reduced CO2 emissions—the study will examine a variety of …

Analysis Of Stress And Strain Concentrations Around An Elliptical Hole Via Finite Element And Response Surface Methodology, Somaya M. Aiad, Tawakol A. Enab, Mona A. Aboueleaz

Mansoura Engineering Journal

The current investigation aims to study the stress and strain concentration factors (Kσ and Kε) around a central elliptical hole in a rectangular plate under uniaxial and biaxial loads. Finite element and response surface methods (FEM and RSM) were used to predict the values of Kσ and Kε in isotropic and orthotropic material rectangular plates. Thus, the finite element models were built using ANSYS commercial FEM software to obtain the values of Kσ and Kε for some designed cases. Moreover, the response surface methodology was applied to limit the required number of FEM runs based on the number of variables. …

Postmodern Architecture In Thailand 1982–1997 : Key Concepts And Case Studies, Santirak Prasertsuk, Winyu Ardrugsa

NAKHARA (Journal of Environmental Design and Planning)

Since the 1960s, Postmodern architecture has been popular in Western societies. It emerged as a response to the Modernism style by rejecting the abstract elements of architecture and included a return to the communication of architectural meaning for the public. This approach led to the representation of architectural elements from the past and re-considered how culture was reflected in design. Postmodern architecture became popular in Thailand during the 1980s, resulting in the creation of numerous Postmodern buildings in all regions of the country. The objective of this article is to characterize Postmodern architecture in Thailand from 1982 to 1997 (2525–2540 …

Optimization Of Envelope Heat Gain And Interior Daylight Illuminance In Building Facade Design Under Reflectance Limitations : A Case Study Of Office Buildings In Thailand, Sarin Pinich, Kantaphong Srimuang, Atch Sreshthaputra

NAKHARA (Journal of Environmental Design and Planning)

The popularity of using glass as the main building envelope material in commercial high-rise buildings has brought about numerous legal actions in recent years due to the widespread impact of the visible light reflectance of glass facades on the surrounding area. However, choosing suitable reflectance values for glazing the building facade remains a viable solution to lessen envelope heat gain and reduce cooling energy demand. Despite this, maximizing daylight is essential to maintaining healthy vision and the circadian rhythm of the building users. As a result, finding the optimal solution for envelope glass property selection to provide minimum heat gain …
