Effect Of A Geothermal Heat Pump System On Cooling Residential Buildings In A Hot, Dry Climate, Rania Rushdy Moussa, Ayman H. Mahmoud
Effect Of A Geothermal Heat Pump System On Cooling Residential Buildings In A Hot, Dry Climate, Rania Rushdy Moussa, Ayman H. Mahmoud
Architectural Engineering
ABSTRACT In the last century, electricity demand has doubled due to urban expansion, which has contributed to the formation of more urban heat islands (UHI) and the appearance of environmental hazards such as the global climate change phenomenon. Since residential buildings are considered the main electricity consumer sector in Egypt, they consume up to 42% of total energy consumption, which contributes to increasing temperatures and constitutes UHI in cities. In this context, the research aims to examine the effectiveness of using the closed vertical loop geothermal system (GSHPCV) for cooling residential buildings in a hot, dry climate, such as Cairo, …

Optimizing Phase Change Material On Opaque Building Envelope To Reach Nzeb, Mennatallah Hassan, Khaled Ragheb Dewidar, Mostafa Ismail Rifat, Ashraf Nessim, Aly Assem Abdelalim
Architectural Engineering
Designing a net Zero Energy Building nZEB envelope with high thermal comfort and low energy consumption is vital nowadays. There is some established specialized software for building optimization design, but these programs are time-consuming, expensive, and demand many data input of building parameters. Therefore, it is difficult to follow the optimization procedure. The aim of this research is to present a novel study to optimize the use of Phase Change Material PCM on opaque building envelope using a multi-objective optimization tool. Python (3) is employed to implement EnergyPlus to minimize the initial cost of PCM in commercial buildings, running cost …
The Impact Of Biophilic Attributes On University Students Level Of Satisfaction: Using Virtual Reality Simulation, Amira Mohamed Mahrous, Khaled Dewidar, Mostafa Refaat, Ashraf Nessim
The Impact Of Biophilic Attributes On University Students Level Of Satisfaction: Using Virtual Reality Simulation, Amira Mohamed Mahrous, Khaled Dewidar, Mostafa Refaat, Ashraf Nessim
Architectural Engineering
Biophilic design is a new approach that can enhance human psychological well-being. Most recent studies focus on applying biophilic design to hospitals or office buildings, not academic buildings. While usually ignored, students' level of satisfaction is one of the most important key indicators for a successful learning environment. This paper aims to identify the biophilic design attributes that can potentially contribute to enhancing the students' level of satisfaction. This will be done through an experimental research design using virtual reality in a design studio at The British University in Egypt. Each participant (N = 52) was exposed to the existing …
Optimization Of Plastic Waste Integration In Cement Bricks, Yara Salah El-Din El-Metwally
Optimization Of Plastic Waste Integration In Cement Bricks, Yara Salah El-Din El-Metwally
Architectural Engineering
Implementing plastic waste in construction materials is a sustainable disposal method to overcome plastic pollution. The current study aims to optimize the integration of plastic waste in cement bricks regarding their thermomechanical properties in order to develop an eco‑friendly building material. Polyethylene terephthalate (PET) and high‑density polyethylene (HDPE) partially substituted cement with different ratios (0, 2.5, 5, 7.5, 10, 20%). The type that achieved better thermomechanical performance further replaced the other brick components; sand and coarse aggregates to determine the optimum replacement scenario and best design mix. Laboratory experiments have been carried out to measure the compressive strength, indirect tensile …

Over the last decades, plastic waste (PW) has increased exponentially and has become a serious threat to our planet, aquatic system and human health. Recycling or reusing PW in producing ecofriendly materials is an efficient solution to reduce plastic pollution and to minimize the depletion of raw materials as well. Previous studies have shown promising potentials of using PW in the construction sector, such as binder, aggregate, or substitute of cement and sand in concrete, brick or mortar. Laboratory results indicate that implementing plastic waste as aggregates in cement composites obtains higher thermal resistance and acoustical performance. However, a reduction …
Techno-Economic Evaluation And Environmental Benefit Of Pv-Based Electric Vehicle Charging Station On University Campus, Rania Rushdy Moussa
Techno-Economic Evaluation And Environmental Benefit Of Pv-Based Electric Vehicle Charging Station On University Campus, Rania Rushdy Moussa
Architectural Engineering
Smart utilities comprise an important aspect of modern smart cities. The aim of this work is to present a case study for implementing a solar- energy-based electric vehicle charging station (for the first time on a campus in Egypt) at the British University in Egypt. The total amount of energy needed for charging each electric vehicle (EV) was estimated to be 13.3—16.2 kWh. The EV is operated by 12 batteries. The station was designed to provide energy sufficient for charging up to two vehicles daily during summer. Thus, the station sizing was based on the provision of 16.2 KW and …
The Aesthetic Effect Of Photovoltaic Cells On The Building Facades, Khloud Khalid Eldamshiry
The Aesthetic Effect Of Photovoltaic Cells On The Building Facades, Khloud Khalid Eldamshiry
Architectural Engineering
Technological advancement in building incorporated photovoltaic (BIPV) has transformed the façade of the building into a generator powered by renewable energy sources. The BIPV facades are designed to provide energy production alongside traditional design goals such as aesthetics art and environmental control. However, the problem is that architectural design goals sometimes conflict with energy performance such as visibility and daylight versus maximum power output. In this context, the use of renewable energy sources such as solar energy seems to be worthwhile as they are numerous and have enormous environmental and economic prospects. This study aims to provide a new entrance …

Construction projects are associated with construction and demolition waste (CDW) generated at different stages. In Egypt’s case, the CDW problem has become a significant challenge, and the need to find sustainable solutions is overwhelming. Based on recent investigations in the literature, it was found that six main factors are affecting CDW reduction (CDWR) as follows: (1) waste-efficient materials procurement measures; (2) waste-efficient materials procurement models; (3) green materials procurement approach; (4) legislation; (5) culture & behaviour; and (6) awareness. In this study, a representative sample of Egyptian construction firms was screened to (1) investigate the applicability and effectiveness of CDWR …

This work investigates the benefits of performing Life Cycle Assessment (LCA) using Building Information Modelling (BIM) techniques on a case study management process. This provides insights for reducing the environmental impacts of building materials and elements along the life cycle of a concrete residential project in Egypt. The study follows the LCA ISO 14040 and 14044 guidelines, local materials database, Revit modelling and One-Click LCA plugin. The result outlines that most of the environmental impacts occur during the operation and manufacturing phase. It also shows that slabs and beams result in most of the environmental loads. In terms of the …
