Kats, 2003), according to Gregory green buildings are commonly perceived to be a lot more expensive than conventional buildings and often not worth the extra cost. For example, an early 2003 article in the New York Times was entitled “Not Building Green Is Called a Matter of Economics.” This defines the constructing of green building, during construction it is expensive but cheaper at a long-run. Constructing green buildings strengthens the relationship between the building and the environment. (Gregory H. Kats, 2003), “Green Buildings provide financial benefits that conventional buildings do not. These benefits include energy and water savings, reduced waste, improved indoor environmental quality, greater employee comfort/productivity, reduced employee health costs and lower operations and maintenance costs.
Green infrastructure provides solutions that address both human needs and benefit the environment and community. State funding is important but not enough, local communities need to rely on locally generated funds as a long term funding source. Planning for Long Term Operations and Maintenance: Both gray and green infrastructure requires establishment of clear duties of maintenance, a funding mechanism and inspection system. The green infrastructure, however, will also require additional maintenance practices, such as those required to properly identify plants and maintain plants. In addition, green infrastructure is well suited for workforce development programs to create local jobs because of a growing need for employees with skills to install and maintain site-scale
This allow for the planting of larger plants like shrubs and even trees. This thickness of growing media, can be very heavy therefore, the structural integrity of the building which will carry this green roof will need to be considered first before this installation takes place or such consideration are made during the design stage of the building. The intensive green roof requires a dedicated maintenance program including, watering schedule, irrigation and
CHAPTER 1: INTRODUCTION 1.1 Introduction Green roofs are referring to any type of roofs that a green technology incorporated in it. Strategy of green roof is to develop a sustainable design which saves energy for cooling purposes due to its insulation effects. There are multiple reasons of green roofs are constructed which is as spaces for people to use it, as architectural features, to add value to property or to achieve particular environmental benefits (for example, improving air quality and internal thermal comfort, and insulation of a building against heat gain or loss). It also helps to invest in the protection of our environment by diminishing developmental impact on our communities while providing a fresh approach with visually appealing organic architecture. Then it potentially contributes ideal architectural union of aesthetics, and economics.
There are different types of renewable energy such as solar power and hydropower. Solar power can be used in remote areas where it is too expensive to use electricity (“Solar Solution to the Growing Energy Problem.”). It can efficiently power everyday things. Solar power is pollution-free. It has a low maintenance cost.
The wind and solar energy are omnipresent, freely available, and environmental friendly. The wind energy systems may not be technically viable at all sites because of low wind speeds and being more unpredictable than solar energy. The combined utilization of these renewable energy sources are therefore becoming increasingly attractive and are being widely used as alternative of oil-produced energy. Economic aspects of these renewable energy technologies are sufficiently promising to include them for rising power generation capability in developing countries. A renewable hybrid energy system consists of two or more energy sources, a power conditioning equipment, a controller and an optional energy storage system.
They are found in all types of fields such as energy , green building, environmentally preferred purchasing, green chemistry, green nanotechnology, green architecture, sustainable development, green computing etc. II. GREEN BUILDING Green building refers to both a structure and using of processes that are environmentally responsible and resource efficient throughout a buildings life cycle: from sitting to design, construction, operation, maintenance, renovation and demolition. A well maintained cooperation is required for this to work. The main goals are utility of the building, durability, and comfort of the occupants.
Consequently, using green plastics are a must in order to conserve the environment from any harm. Briefly, green plastics or bio-plastics, are plastics that are biodegradable and are usually made mostly or entirely from renewable resources. That issue was aroused by the pollution that was made by the accumulation of plastic products in the environment that adversely affected wildlife and led to the death of many marine birds and animals. As a result of this disaster, scientists in 1990s proposed that we should use green plastics as environmentally friendly alternative to diminish the harm on wildlife and on the environment. However, some people are opposed to that proposal simply because green plastics are extremely expensive in comparison to conventional plastics, because they require innovative methods to create them which bring the cost up.
So, the concept of green computing has been introduced to us in 1942. Green computing also known as green technology or green IT which is environmentally sustainable use of computers. Green computing can define as the research and execution of designing, manufacturing, using and disposing of computers, servers and related subsystems such as monitors, printers, storage
Michigan State University’s Green Roof research team states, “Green roofs involve growing plants on rooftops, thus replacing the vegetated footprint that was destroyed when the building was constructed” (Michigan State University). This vegetation is most often atop a high-quality waterproof membrane that prevents leakage. There are two main types of green roofs, extensive and intensive. Extensive roofs require no maintenance and plants must be able to survive on rainwater. Generally these roofs are inaccessible to the public.
