Abstract: Green real estate investment paradigm brings a new investment option to property investors. The green office buildings are gradually replacing the conventional buildings due to the fact that green office building provides better return such as high market value and rental value, high occupancy rate and cost savings. Energy and water efficiency, indoor environmental quality, sustainable site planning and management, materials and resources and innovation are prerequisite green criteria that determine the level of greenness which distinguish it from a non-green office building. This paper discusses the green attributes in office building and its enhancement to return on investment.

Abstract: In order to solve the problem that high-rise users can't install traditional solar water heater for limited area and the problem that the utilization rate of panel position fixed solar energy is low, this paper proposed a new design of high-rise building integration solar water heater, which can make solar water heater integrate with high-rise building, and has the function of tracking sunlight automatically in real time, raising the utilization ratio of solar energy, and prolonging sunshine time. In addition, the auxiliary electrical heating system can be intelligently started or closed by setting the temperature sensor in the storage water tank of water heater. Humidity sensors automatically control the stretch of panel according to humidity, which can effectively protect the panel and prolong its life, and preferably realized green and energy-saving architectural concept.

Abstract: Nowadays, the shortages of fossil based energy on the earth and the pollution caused by using them is a noticeable problem that people are challenging with. As a result, human try to use natural resources vastly instead of fossil-based ones to reduce their consumption dramatically. In this circumstance, the role of architects are more important than ever in reducing the need for energy by proper designing likewise the past construction history. Green building design criteria emphasizes the energy-efficient performance of fenestration materials. Iran is a country comprising of four main different climatic areas. Selecting materials and using proper techniques for a building project is a challenging task in each part. Ancient buildings were built by different materials, techniques and forms in different parts of this country. One of the main parts of climatic areas in Iran is the hot and dry climates such as deserts. The appropriate materials and techniques which were used in ancient buildings in this part of the country to make this area comfortable for people will be investigated in this paper. Moreover, the buildings of Kashan, located in the desert part of Iran, will be mentioned as case study.

Abstract: This paper discusses the factors that lead to green buildings operations and maintenance (O&M) problems in Malaysia. Several factors that lead to complexities in managing and maintaining green buildings have been highlighted by several scholars and practitioners in the construction industry. However, the criticality of these factors has yet to be empirically explored in the Malaysian context. A questionnaire survey was carried out involving green building maintenance management teams and Green Building Index (GBI) facilitators in Malaysia. Frequency and criticality index calculations were carried out to rank the factors according to level of criticality. The result indicated that the most critical factor that leads to green building O&M problem is the failure to consider the aspect of maintainability during the design stage. It is hoped that the findings of this study will shed light to green building designers and management teams on the critical aspects that demand scrutiny and consideration for successful O&M of green buildings in Malaysia.

Abstract: Due to the current resource depletion rates, as well as the growing need toward energy and water efficiency, Governments and the private sector adopted the concept of the Green Building, given the fact that buildings are responsible for energy and raw materials on a large scale. That need is clearly manifested in the developing countries facing energy efficiency challenges. Hence, this research highlights the efforts of the governmental and the non-for-profit organizations; represented by Lebanese Ministry of Environment, Ministry of Energy and Water, Lebanon Green Building Council (LGBC) and funded by the International Finance Corporation of the World Bank. The research summarizes the opportunities and challenges of adopting this concept to the benefit of Lebanon and other countries undergoing the same circumstances and facing the same challenges. In the process of reaching a conclusion, the researcher adopted the analytical and the case study methods through two main axes. The former attends to the theoretical studies which include the definition, the principles, the benefits and the global and local rating system of the Green Building. The latter axis addresses the Lebanese experiment through the review of the Opportunities and the Challenges facing the Green Building in Lebanon, and the ARZ Building Rating System. It also illustrates and analyzes a pioneering project in Lebanon that employed the green building patterns, the Ammiq Eco-Restaurant in Bekaa region. The paper is concluded by a set of recommendations that can be the foundation for similar experiences aspiring for adopting the green building as a cornerstone in the arena of sustainable development.

Abstract: The national systematic, social requirements for green building development are becoming more stringent. But from the standpoint of the builder, who would contract and implement such a business, such regulations can become a burden working against efforts to promote building. Due to the increase in the initial investment cost associated with green building development, the reality is that voluntary compliance is not readily forthcoming. Thereby, the profitability of green building construction was examined from a cost perspective for a 40-year life cycle cost. As a model example of green apartments, the A Apartment complex was analyzed for its economy. A comparison was made against a standard building for green building design on its initial investment cost, and the energy savings during the occupancy phase, required to offset the cost of investment was calculated. As a result, the A-Apartment investment cost recovery period was approximately 10 years, with about an 8% range of operating profit. If the green building construction business were to be pursued with this long-term view, it is evident that construction of green buildings can be good for business.

Abstract: In present time, the environmental impact of green buildings on inner and outer climate has becomes more apparent. Green buildings are designed to reduce the overall impact of the built environment on human health and the natural environment. Recently, the popularity of green roof is growing in the context of urban landscaping because of its smaller footprint, aesthetic value, insulation benefits and heat island mitigation impact. Greenery roofs are considered to be a part of new technology that allows the use of alternative vegetation. This paper will explore the potentials of using green roofs as an integral part of the building process to save energy. This paper will introduce the energy crisis and will focus on the current crisis in Egypt and the global UHI effect. It will also identify the impact of vegetation as a sustainable approach for UHI mitigation and energy savings. After addressing green roof types, and their functional, and environmental aspects in general. The paper distills these different types to enhance thermal performance in terms of indoor thermal comfort and energy savings with the integration of PV cells within green roof design. This will be empirically examined by DesignBuilder and EnergyPlus Simulation, to explore the possibilities of improving indoor thermal comfort within the studied types. Then the paper will be concluded by a set of recommendations for buildings within Egypt’s climatic settings.

Abstract: Buildings are accounted for around half of worldwide energy consumptions, significantly contributing to global warming and the alteration of natural ecosystems, as proved by recent reports. The role of higher education as a means of comprehensively introducing new generations of architects to the principles and practices of sustainable environmental design is becoming highly significant, although this faces a number of pedagogical and professional barriers. The aim of this study was to identify green building components used in the pedagogcal approach in environmental design studio and to present the state of sustainable education technological practice in Universiti Teknologi Malaysia (UTM). The method used was through observatory studies of environmental design studio for a whole semester to identify the pedagogies used in teaching the environmental design. Lecture inputs, experiment, site visit, field trip, crit, pin up crit and assessment were pedagogies used for the environmental studio were identified as the pedagogy used and the most observed components are active and passive while the activitiespost occupancy are seldom used.
