Costs and Benefits Analysis of LEED Building Projects
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.
Green Architecture
Green architecture is an approach to building which has become more popular in the last 25 to 30 years. Also known as sustainable design, green architecture is a method of design that minimizes the impact of building on the environment. Once thought of as unconventional and nonstandard, both regulatory agencies and the public alike are quickly accepting green architecture as a socially responsible and logical means of construction.
The beginnings of today's green revolution can be traced back to the environmental awareness of the 1960s and European design.
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.
INTRODUCTION
The present world with its sustainable resources, environment and way of life became developed. The population growth, consuming almost all the available resources, to meet people’s needs, should be a major concern. The consumption of material and energy around the world which is about to eliminate the available supply, has increased over the last two decades, especially in the built environment. In order to access other reserves of fuel, the more energy will be needed to use.
“We are consuming the Earth’s natural resources beyond its sustainable capacity of renewal” said by Herman Daly, Beyond Growth, Boston 1996, 61[1] .
Sustainable Design
Sustainable design seeks to reduce negative impacts on the environment, the health and comfort of building occupants, thereby improving building performance. The basic objects of sustainability are to reduce consumption of non-renewable resources, minimal waste, and create healthy, productive environments (“Sustainable Design”). Focusing primarily on the sustainable design principles, there are five, including: low-impact materials, energy efficiency, quality and durability, design for reuse and recycling, and renewability. As sustainability appears to become the necessary trend in architecture, the question concerning the cost versus outcome of “going green” really an investment or a waste of time and money comes to mind. With our research provided below, we believe the expenses may truly be with the investment in the end.
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
When it comes down to it, rethinking how to construct buildings can have huge effects on the environment. According to buildinggreen.com, the four main factors that can have a positive effect on the environment when first constructing a building are design, siting and land use, materials, and equipment. These are things that can be altered to tailor this idea of having greener buildings. From design to completion, many things can be done to make buildings more sustainable. Many of these processes are ignored possibly because of cost or complexity of the project. However, the end results of these processes are extremely beneficial to our environment and people surrounded by this environment. Ultimately, the reward of a healthier environment is worth the cost and inconvenience of completion.
The sustainable interior design has a different main guideline; before esthetics, there is ethics. It has as main objective the healthy, the beneficial or harmful for the health of the people who live in the homes and to preserve the natural environment that surrounds it.
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.
Globally, green buildings are being recognised and accredited, leading to the introduction of various tools and indices with one common objective that is to evaluate, measure, distinguish and sets apart this uniquely designed buildings from the rest. The Diamond Building carries a Green Building Index (GBI) accreditation, a first in Malaysia. Among the achievement of the ST Diamond Building are:
