Cost of Green Building What are green buildings? (Gregory, 2003) defines Green building. “Green” or “sustainable” buildings are buildings that use resources like energy, water, materials, and land more efficiently than buildings that are just built to code. According to (Li & Syal, 2013) (Turner & Arif, 2013), Green Building is defined as: a building that provides the specified building performance requirements while minimising disturbance to and improving the functioning of local, regional, and global ecosystems both during and after its construction and specified service life. (Kibert, 2008 by John Wiley & Sons 2nd edition page 6), described sustainable buildings as “Green buildings virtually always make economic sense on a life-cycle cost
Chapter I Introduction and Background: Green building/Green Design/Green architecture alludes to both a structure and the use of procedures that are environmentally mindful and asset productive all through a building's life-cycle: from intending to design, construction, operation, support, redesign, and demolition. This requires close cooperation of the contractual worker, the architects, the engineers, and the customer at all project stages. The Green Building practice extends and supplements the traditional building design worries of economy, utility, toughness, and solace. A green building (additionally alluded to as supportable building or green construction) is a structure that utilizes an approach that is in charge of the environment
One of the biggest advantages of green roofs is their thermal insulating properties. This is particularly relevant when green roofs are installed over garages, sheds and industrial buildings. Typically these buildings, have poor insulation installed. Many newly built buildings have insulation
Let us go through the benefits we stand to gain when we implement green chemistry * The air becomes cleaner due to less release of harmful chemicals and damages to the lungs is reduced. * Toxic chemicals that causes harm to plants and animals is reduced. * The ecosystem is less disrupted by chemicals. * Clean water becomes available due to less release of toxic wastes into the water. * Exposure to hazardous chemicals lessen.
E- What is the importance of green-house effects? F- What could be done as solution for prevention? Actually green-house effects can be divided in two terms: “First is a natural effect” which maintains Earth warm and habitable and the “Second is an artificial or man-made effect” which enhance natural green-house effects adding gases such as: sulphur dioxide Carbon monoxide; Carbon dioxide; Ozone; Chlorofluorocarbons released
However evidence for physical and non-physical health benefits from urban green space within these projects is unclear. Methodology: A collection of academic and ‘grey’ literature was collected on the health effects of green space and then that was categorized by theme. Results: “weak evidence for the links between physical, mental health and well-being, and urban green space. Environmental factors such as the quality and accessibility of green space affects its use for physical activity. However, many studies were limited by poor study design, failure to exclude confounding, bias or reverse causality and weak statistical associations.” This is important, previous studies haven’t found the right study design to provide significant results.
Global warming, heat waves, and local warming pose a severe threat to people 's health. Mitigation of urban temperatures would be beneficial for most of the human population that nowadays lives in cities. Among others, green roofs deployment can be a valuable mitigation and adaptation measure, depending on climate and on their specific design. Research shows that green roofs can efficiently decrease building energy use with a particular emphasis in decreasing cooling energy demand and can mitigate the urban heat island effect; but they can also provide additional benefits such as a better stormwater management, air-pollution abatement and city beautification contributing to increase urban sustainability and resiliency. Differently from other
The aspect of reduction in air pollution level by green roofs was studied in Chicago. It was estimated that annually per hectare of green roofs are causing 85 kg ha-1 yr-1 reduction in air pollution level. The highest reduction in air pollution level was observed in May and lowest in February . Research carried out in USA to study the effect of green roofs as alternative to land cover shown that green roofs performed considerably well in managing storm water runoff and reducing surface temperatures in comparison to paved and asphalt surfaces. Integrated along with modular green roofs were studied in Georgia and modular green roof in Massachusetts were monitored.
Studies have shown that increases in use of sustainable construction materials in green buildings result in decreases in lower maintenance and energy costs provided sustainable building practices. The need for leadership in energy conservation and related environmental performance has never been greater— not only as a means to further our own interests, but as a way to serve the interests of society at large
Introduction A great way to escape the stresses of day to day life is to have access of an outdoor area. A lush Green space has scientifically proven to be a factor of well being. “Parks, gardens and green space in urban areas can improve the wellbeing and quality of life of people living there,” says a University of Exeter study. As half of the world is urbanized today there is a need to provide artificial green areas which are developed considering the need of adjacent communitirs.Green infrastructure is the city and region's alternative infrastructure. It protects the water quality of our streams, rivers and drinking water supplies.
