Green Roofs and Green Walls for Biodiversity Conservation: A Contribution to Urban Connectivity?

Green roofs and walls have recently emerged as conservation tools, and they offer promising additional opportunities to enhance biodiversity in cities. However, their ecological conditions remain poorly considered when planning wildlife corridors. To discuss the role of vegetated buildings in landscape connectivity, we reviewed the ecological and technical specificities of green walls and green roofs in light of the key factors concerning urban wildlife (patch size, quality, abundance, and isolation). Green roofs and walls show limited patch sizes, distinct habitat quality at the building scale, and limited redundancy of patch quality within the landscape. We also highlight that the abundance of roof and wall patches is often low. Future research is needed to establish if walls can be vertical corridors for wildlife, thereby reducing the isolation of green roofs. We argue that creating 3D ecological connectivity within the city requires substantial modifications of the design and maintenance of existing green building systems. We suggest that research is needed to integrate the biotic and abiotic characteristics of green buildings to make them more closely resemble those of open green spaces.

Possibility of Implement Strategies of Green Buildings in Building Constructions at Kingdom of Saudi Arabia to Achieve Sustainable Development

The aim of this research is to spot light on the strategy of application of green building systems in the building constructions at Kingdom of Saudi Arabia to Achieve sustainable development, in order to conserve of energy consumption to increase the control and upgrade of thermal efficiency of buildings. Since the summer season of Saudi Arabia is very long, and the sun shines for long time, it is possible to use and application of solar cell systems for generating clean electrical energy, where it is possible to use such electrical energy in irrigation of special plants used as components for the systems of green buildings, consumption of energy will be less, environmental will become more healthy, the efficient of buildings will be better too, because of using such alternatives. First promote the phenomenon of Agriculture inside the houses and around. The advantages of building such system, means that the natural ventilation inside houses increase reducing building energy consumption and improving the indoor environment conditions have become more convenient. Compared with mechanical ventilation or air-conditioning system, there is more potential in the natural ventilation method providing better indoor air quality, while maintaining a healthy and comfortable indoor thermal environment, in addition to reduce pollution, and to save energy for the future generation, and will also increase the aesthetic aspect of buildings. I. Introduction Saudi Arabia is blessed with an abundance of different energy, foremost of which is the sun, which is alternative energy petroleum, which are called clean energy. The summer of Saudi Arabia is too long, and the sun shines for long time, from which to generate electricity that can be used in different sectors, notably the construction sector or the so-called green buildings, as well as contributing to the preservation of the national inventory of petroleum, which is the right of new generations. Saudi Arabia has ―Council of Scientific Society of Green Buildings‖, non-profit society, founded in 2007 on the initiative of a group of academics and engineers and those interested in the field of environmental construction and science knowledge. It holds an accreditation World Green Building Council, prepared and participated in many workshops and events, local and international conferences for the manufacture of green buildings. Aims to create human consciousness and the preservation of heritage and urban environmental knowledge and support and employment practices optimized for high- efficiency construction in Saudi Arabia, The green building movement focuses on reducing the overall environmental impact of new and existing buildings through various methods, such as the use of recycled materials, energy efficient design, and water protection and conservation Most of buildings and Villas in Kingdom of Saudi Arabia seems very huge and very beautiful architectural design. But most of these buildings lack the highlight to plants, which adds a beautiful and elegant view for buildings, which will work to soften the atmosphere, and will also work to reduce the costs of energy consumption. of course there are ways exist even in Saudi Arabia for alternative energy generation and clean that it can be used to irrigate plants, which also means that the use of these plants to protect buildings from the sun warm temperatures. It also helps reduce energy consumption inside houses, and reduce the cost in the electrical bill, and maintain a clean and comfortable environment. The malpractice of the current constructional mode will increase in the energy consumption. While the Taif like other governorates of the Kingdom have a strong interest in the theme parks and the streets are coordinated through the presence of specialists on the subject of landscaping, which calls for attention of the citizens, for the value of these plants aesthetically as well as the physical benefit. This confirms the possibility of growing some plants in home gardens, as well as using different types of plants contribute to the preservation of buildings, by reduced degrees of heat, which means reducing energy consumption also. Then we will find that green buildings are financial feasibility and in many times better than conventional buildings. Therefore, governments should grant preferential to the enterprises that produce green buildings to stimulate the development of green buildings, and encourage people to use such building system, through using different types of media. As well as create sufficient awareness among citizens extent of the importance of using this type of building systems. Green buildings are commonly perceived to be a lot more expensive than conventional buildings and often not worth the extra cost, and now green construction is gaining increasing attention in the

Performance of LEED Energy Credit Requirements in European Countries

Construction industry influences the environment a great deal by using different resources. Efficient use of resources is important for sustainability considerations. Heavy consumption of energy is one of the reasons causing adverse impacts on the built environment. The interest in sustainable construction is growing worldwide. Green building systems are used to certify the projects as green buildings in different countries. All these systems have similar approaches to build sustainably and they all highlight requirements related to energy consumption with a significant emphasis. One of the most recognized green building certification systems, LEED addresses energy optimization, green power and on-site renewable energy in much detail. The maximum credit points can be achieved from “energy and atmosphere” category in LEED. However, the use of LEED in countries other than the U.S. can be difficult as local conditions and practices are influential in earning credentials. This study aims to review the practices of “energy and atmosphere” category of LEED v3 2009 New Construction in European countries. Analysis of practices in selected countries is made based on credit performances, which can display variations depending on local conditions. It is expected that practitioners in these countries will benefit from the credit patterns, providing improved insights about on-site real applications.

Developing a green-building design approach by selective use of systems and techniques

ABSTRACTBuilding sustainability is subject to rational use of green-building systems and techniques. A suitable combination of these systems and techniques is at the heart of design parameters. To achieve user comfort and health as well as environmental protection and long-term economic benefits, designers must optimize combinations of particular systems and techniques. It is imperative to have efficient design strategies for achieving optimum solutions and effectively leading the complex process of selecting system and technique combinations to be integrated in overall design. With goal to optimize design effort, this research aims to propose different methodologies to help incorporate various green-building systems and techniques in design process. Systems and techniques prioritized by relative weights may ease the design process. Hence, with a focus on semi-arid climatic conditions, interviews are conducted from researchers and building practitioners who help express design priorities. Use of these priorities through the proposed design approach in case study of a sustainable residential building validates the workability of design methodology. Consequently, a model is proposed for integration of all three sustainability dimensions as design criteria in building simulation programs, facilitating the realization of green-building design.

Despite going global, LEED certification is essentially a US tailored approach to encourage Green Building businesses and practices. The assumptions of incentive packages and tax breaks, points rewarded for the use of certain types of recycling, weights and points – all these have many local biases for US companies and practices. Before adoption in another country, these assumptions and biases have to be clearly spelled out and checked. In fact, a Green Building certification has to be home-grown to suit economical, cultural and technological conditions. This paper shows how different countries can adopt a customized Green Building Evaluation Code and still be recognized, the case study is Egypt Green Pyramid ranking system. The research aims to evaluate the adoption of the green building systems in Egypt and propose the suitable score and elements to the Egyptian society. Some localized issues for example are the increased encroachment on agricultural land, the abundant desert land, energy crisis and the reduced share of Nile water.

Moving Into Green Healthy Housing

Green building systems have proliferated but health outcomes and associated costs and benefits remain poorly understood. To compare health before and after families moved into new green healthy housing with a control group in traditionally repaired housing. Mixed methods study in 3 Chicago housing developments. Public housing and low-income subsidized households (n = 325 apartments with 803 individuals). Self-reported health status, visual assessment of housing condition, indoor air sampling, and Medicaid expenditure and diagnostic data. Medicaid expenditures and International Classification of Diseases, Ninth Revision codes were modeled using a generalized linear model with γ distribution and log-link. Housing conditions and self-reported physical and mental health improved significantly in the green healthy housing study group compared with both the control group and the dilapidated public housing from which the residents moved, as did hay fever, headaches, sinusitis, angina, and respiratory allergy. Asthma severity measured by self-reported lost school/work days, disturbed sleep, and symptoms improved significantly, as did sadness, nervousness, restlessness, and child behavior. Medicaid data in this exploratory study were inconclusive and inconsistent with self-reported health outcomes and visual assessment data on housing quality but hold promise for future investigation. Possible sources of bias in the Medicaid data include older age in the study group, changes in Medicaid eligibility over time, controlling for Medicaid costs in an urban area, and the increased stress associated with moving, even if the move is into better housing. The mixed method approach employed here describes the complex relationships among self-reported health, housing conditions, environmental measures, and clinical data. Housing conditions and self-reported physical and mental health improved in green healthy housing. Health care cost savings in Medicaid due to improved housing could not be quantified here but hold promise for future investigations with larger cohorts over a longer follow-up period.

Optimizing tradeoffs among housing sustainability objectives

Abstract The sustainability of housing units can be improved by integrating green building equipment and systems such as energy-efficient HVAC systems, building envelopes, water heaters, appliances, and water-efficient fixtures. The use of these green building measures often improves the environmental and social performances of housing units; however they can increase their initial cost and life cycle cost. This paper presents a multi-objective optimization model that is capable of optimizing housing design and construction decisions in order to generate optimal/near-optimal tradeoffs among the three sustainability objectives of maximizing the operational environmental performance of housing units, maximizing the social quality of life for their residents, and minimizing their life cycle cost. The model is designed as a multi-objective genetic algorithm to provide the capability of optimizing multiple housing objectives and criteria that include minimizing carbon footprint and water usage during housing operational phase, maximizing thermal comfort, enhancing indoor air and lighting quality, improving neighborhood quality, and minimizing life cycle cost. An application example is analyzed to illustrate the use of the developed model and evaluate its performance. The results of this analysis illustrate the novel capabilities of the model in generating 210 near-optimal tradeoff solutions for the analyzed housing example, where each represents an optimal/near-optimal and unique tradeoff among the aforementioned three sustainability optimization objectives of maximizing the operational environmental performance of housing units, maximizing the social quality of life for their residents, and minimizing their life cycle cost. These novel capabilities of the developed model are expected to improve the design and construction of housing units and maximize their overall sustainability.
