- Egypt’s Sustainable Development Strategy: Vision 2030 calls for renewable energy plans and the adoption of a sustainable development approach. Given the government’s gradual removal of energy subsidies for local citizens and the current energy crises, the study in hand aims to detect potential investment zones for free fossil fuel energy production. Site analysis for renewable energy allocation using GIS to identify potential capability to locate a renewable energy source was applied in the Sinai Peninsula in Egypt. The study used an accumulative co-relation matrix between different development sectors, Sinai’s geographical location and promising future investment scenarios. A set of data analysis process was developed to examine potentials and constraints. The analysis revealed that 36% of the area is suitable for the development of solar farms and a further 4% for wind farms. These findings could help decision makers to fill the gap between the country’s future energy needs and its available natural sources. Applying this methodology across the different areas offering similar potential in Egypt would help to identify more likely locations for renewable energy production. Wider replication of the method could also point to the significant contribution that different zones in Egypt, and even in other zones within the Middle East region, could make towards a more sustainable future.

- Green building rating systems are voluntary tools intended to promote sustainable building process through approaching several environmental issues that include sustainable design parameters related to the construction site and others related to its surrounding context. Decision making software support tools and methods are needed to guide practitioners on minimizing building’s environmental impact especially for early design decisions. Hence, the study shows how Geographic Information Systems (GIS) is used as a decision-making support tool for assessing location and transportation (LT) together with sustainable site (SS) categories for Leadership in Energy and Environmental Design (LEED) green building rating system. The methodology is applied on the 10th of Ramadan city in Egypt; creating land suitability analysis for these two LEED categories. The analysis considers sensitive land protection, high priority development sites, surrounding density and diverse uses, and access to quality transit on the context level. It also analyses lithology type and condition as well as habitat and open spaces protection on the site level. The result shows the potential role of integrating GIS analysis as a tool for site selection credits for LEED rating systems. This allows for more data integration to set a solid base for objective decision making process based on contextual conditions. The method can be generalized and applied in similar contexts in order to attract private investments for green construction especially in new development areas.

Rapport (övrigt vetenskapligt/konstnärligt)abstract
- This booklet is a report for a case study visit during four day field trip, a group of nine PhD students and their supervisors – all part of the National Research School for Architecture and Planning in the Urban Landscape, APULA – set out to explore what may be considered the outback of Western Europe’s conurbations, the transnational region of Kiruna -Narvik.Both “remote” and “resourceful”, “threatened” and “thriving” (equally relative notions), this region seemed to offer possibilities to reflect upon many of the current tendencies influencing contemporary planning practice and research.

The Potential of Using Passive Cooling Roof Techniques to Improve Thermal Performance and Energy Efficiency of Residential Buildings in Hot Arid Regions
- 2022

Tidskriftsartikel (refereegranskat)abstract
- In hot dry regions, the building envelope receives abundant solar radiation, which contributes to heat stress and indoor thermal discomfort. To mitigate overheating inside spaces, cooling is the main basic requirement during most of the year. However, due to the harsh climatic conditions, buildings fail to provide passively the required comfort conditions. Consequently, they are fully dependent on-air conditioning systems, which are huge energy consumers. As roofs are exposed to the sun throughout the daytime, they are estimated to be the main source of heat stress. In return, they can contribute significantly to achieve optimum comfort and energy savings when efficient design strategies are used in an early design stage. To examine the potential for cooling load reduction and thermal comfort enhancement by using cooling roof techniques in residential buildings, a study was performed in the city of Biskra (southern Algeria). Accordingly, an in-field measurement campaign was carried out on test-cells during five days in summer. Three different cooling roof techniques were addressed: (a) cool reflective white paint (CR), (b) white ceramic tiles (CT) and (c) a cool-ventilated roof (C-VR). These roofing alternatives were investigated by monitoring both roof surface temperatures and indoor temperatures. Comparative analysis showed that a cool-ventilated roof is the most efficient solution, reducing the average indoor temperature by 4.95 °C. A dynamic simulation study was also performed based on TRNSYS software to determine the best roofing system alternatives in terms of thermal comfort and energy consumption, considering the hottest month of the year. Simulation tests were run on a base-case model representing the common individual residential buildings in Biskra. Results showed that a double-skin roof combined with cool-reflective paint is the most efficient roofing solution. By comparison to a conventional flat roof, meaningful improvements have been achieved, including reducing thermal discomfort hours by 45.29% and lowering cooling loads from 1121.91 kWh to 741.09 kWh.

A Comparative Monitoring Study of Indoor and Outdoor Heat Stress in Four Different Urban Typologies in Cairo

- Rapid urbanization and increasing heat exposure from climate change in combination with the urban heat island effect has become a contemporary pervasive threat to human health. We monitored four urban typologies with temperature and humidity sensors during the 2015 summer peak in Cairo, Egypt to evaluate which typologies could potentially reduce adverse impacts on human health. Our mixed methods approach included qualitative surveys to gauge how people perceived heat stress. While our monitoring revealed that indoor temperatures were cooler by 1.64°C in the low-density typology relative to outdoor temperatures, the minor indoor temperature differences revealed that building envelopes had little impact on protecting inhabitants. The study points to the urgent need for more comprehensive empirical monitoring of indoor heat stress in urban areas. Future research would benefit from greater interdisciplinarity so that a more inclusive range of heat stress scenarios, particularly in urban areas in the Global South, can be anticipated, and thereby monitored, mitigated and potentially avoided in order to reduce human health insecurity impacts from climate change.

A comparative study for human aspects in acclimatization of adobe vernacular architecture. A case from Denmark and Egypt
- 2014
-
Konferensbidrag (refereegranskat)abstract
- Today’s architecture swarms with concepts of energy and resource efficient buildings. In contrast, vernacular buildings are characterized by low-tech climatic responsive strategies and by their inhabitants’ resource and energy savings practices during construction and operation of their dwellings. That makes vernacular buildings highly relevant to resource efficiency in contemporary building research. The main focus of this study is to explore and analyse human behaviour to reach responsive and conscious resource efficient solutions in two different climatic context; in Egypt and Denmark. The aim is to suggest sustainable principles out of human conduct for contemporary resource efficient building practice. Though Danish and Egyptian climates and cultures are very different from each other some human approaches to sustainability appeared to be similar. That was evident through a comparative analytical study applying case-study methodology for two courtyard adobe dwellings; one in each country. The paper contributes to existing vernacular sustainable building studies by filling a knowledge gap on how human factors is a key parameter in acclimatization in buildings and how that can influence resource efficient building practice.
