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, …

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

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 …

A Review On Sustainable Disposal Of Plastic Waste By Integration In Construction Materials, Yara S. El-Metwally, Iman El-Mahallawi, Khaled M. Dewidar, Mostafa R. Refaat

Architectural Engineering

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 …

This is due to the traditional construction method used in the construction of schools which consumes time and generates a vast amount of waste. In addition, the changing demands of the occupants may confront the need for future expansion or complete changeover. With …

Corporate Social Responsibility Of Architectural Design Firms Towards Sustainable Built Environment In South Africa, Ayman Ahmed Ezzat Othman

Architectural Engineering

The construction industry makes a vital contribution to the social and economic development of every country. Buildings provide their users with places for housing, education, culture, medication, business, leisure and entertainment. None of these buildings will perform its function unless supported with efficient road networks, superlative telecommunications facilities, water and electricity. On the other hand, the construction industry has major impacts on the environment. It is a very large consumer of non-renewable resources, a substantial source of waste, pollution, land dereliction and energy consumption. This highlights the responsibility of present generations to use the available resources in a way that …
