LEED, or Leadership in Energy & Environmental Design, is a certification program for green buildings with stringent requirements for building energy efficient and environmentally responsible structures. Some requirements of this program include specific building materials, smart grid capable, gray water reclamation systems, green space minimums, high levels of insulation and low thermal transfer glass (US Green Building Council). Green buildings are a must if we are to sustain our current level of growth. Despite the higher initial cost of these buildings, the long term energy savings make these buildings a smarter choice for
A green building (also referred to as sustainable building or green construction) is a structure that employs an approach that is responsible for the environment besides being efficient in regard to resources all through its life cycle: This is from selecting the site to designing it, constructing, operating, maintaining, renovating and demolishing it. To achieve this, the client, the engineers, the architects and the entire design team closely cooperate at all stages of a project (Yan and Paliniotis, 2006). Practicing Green Building complements and expands the conventional building design areas of comfort, durability, utility and economy.
As the environmental problems become more and more serious these years, especially that intense negative impact that buildings in modern cities bring to the cities, the concept of Green Building is being more and more important considered by local and federal government. According to the U.S. Green Building Council (USGBC), a green building is one that utilizes design and construction practices that significantly reduce or eliminate the negative impact of buildings on the environment and the building's occupants. Besides the more and more advanced building structure and technology, the main goal of green building is to protect the health of the occupants, save energy and reduce pollution to environment. There are many certifications of green buildings to judge whether the building meets the standard of green buildings and what environmental performance level is this building at, to help government regulators, building professionals and consumers to see better how this building can be improved and what is its impact on human beings and environment. Such green building programs include Leadership in Energy and Environmental Design (LEED), Environmental Protection Agency's Energy Star program, National Association of Home Builders (NAHB Green), etc. Among them, LEED is one of the most popular certification programs that give the building credits for its environmental performance. In this essay, I will discuss the costs and benefits of different types of building projects that were certified by LEED.
Beginning in the 1960s, our society has become increasingly aware of mankind’s negative impact on the earth. We have heard more about topics such as pollution, water contamination, Acid Rain, and Global Warming. All of these environmental concerns have displayed a need for more environmentally sensitive development. Environmentally responsible residential development is defined by Brewster as, "the production of building and communities that conserve resources and reduce waste through more efficient use of materials, energy, and water; that are more durable and useful; and that are designed for adaptive use or the recycling of their materials" (33). By definition alone, this type of development fits the description of sensitive development. I propose that we, as a society, must provide more incentives to encourage development such as environmentally responsible residential houses, because it will help reduce pollution, conserve limited and natural resources, and ensure a sustainable future.
Green building has come forth over the past decade as a positive movement to produce high-performance, energy-efficient structures that improve comfort and health for resident, meanwhile, minimizing environmental impacts. Nevertheless, a common sense that green features is expensive and not suitable for affordable housing. Recent studies are showed that green buildings have a modest initial cost premium, but the long-term benefits far exceed the additional capital costs. For this report, I will introduce a financial analysis -Net Present Value (NPV), and discuss the impacts of NPV analysis for green affordable housing.

Well-recognized cities worldwide have built over the years great buildings with a variety of designs and concepts however consequently too much building has been making grievous decrease on energy efficiency. Now, “Green Architecture” has been popularized and as a result a modicum of energy efficiency has increased and also it has substantiated a new perspective, a new versatile way on architecture.
In order to measure whether a building has achieved the definition of "green", each LEED classification system incorporates seven categories: Sustainable systems, Water Efficiency, Energy, and Atmosphere, Materials and resources, Quality of the indoor environment, Design
The beginnings of today's green revolution can be traced back to the environmental awareness of the 1960s and European design. New construction techniques have lead to the development of innovative materials and design concepts. Green buildings are designed, constructed and commissioned to ensure they are healthy for their occupants. Successfully designed green projects can involve an extensive array of factors, ranging from the resourceful use of materials, to careful consideration of function, climate, and location.
Green Building may be defined as the processes of planning, designing, constructing and operating a building, while taking into consideration: the quality of the indoor environment, selection of the materials used, the way of using energy and water and the effect of the building on the site.
