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
Unlike other conventional materials, the rammed-earth wall will have less carbon footprint and is environmentally sustainable. Another goal is to review the possible innovative earth-construction methods and study the minor details that can help improve its use. 6.

Sustainable Construction Sustainable construction aims to reduce the environmental impact of a building over its entire lifetime by applying the principles of sustainable development to the comprehensive construction cycle. It is a holistic approach process from the adoption of building designs, construction methods, utilizing materials that are environmentally friendly until the management of the resultant waste. It aims to optimize the use of natural resources reducing our dependence on raw building materials to restore and maintain harmony between the natural and built environments while encouraging economic equity as buildings and construction works contributes to the largest single share of global resource use and pollution emission. Some examples of sustainable materials and products are steel, glass, as well as recyclable substitutes for concrete. Steel Steel has been known to be a highly reusable material where all products are 100% recyclable; it is able to be recycled repeatedly without any degradation be it in terms of properties or quality performance.
The main goals are utility of the building, durability, and comfort of the occupants. The main objective is to reduce the overall impact of the built environment on human health and natural environment by efficiently using energy, water and other resources, protecting occupant health and improving employee productivity, reducing waste pollution and environmental degradation. One way to construct a green building is to use natural materials or to retrofit the existing building through public schemes for energy efficient refurbishment. A.
Green Business: A Brief Overview After the inception of the concept of green business or sustainable business practices, several researchers have conducted their studies on this topic.They have examined and explained this concept in different ways. World commission on environment and development (1981) have explained sustainable development practices as ,”development that meets the needs of the presents without compromising the ability of future generations to meet their own needs.” Smith(2013) define “green business” as business practices that are viewed as environmentally sound, including the use of organic and natural products to build factories provide protection against emissions and environmental friendly sourcing of materials. Similarly, Zsolani (2002) defines green business as “business that has adopted the concept of environmentalism across the various functions of the
Green marketing offers business bottom line incentive and top line growth possibilities. While modification of business or production processes may involve start-up cost but it will save money or make profit in long run. Companies that develop new and improved products and services with environmental impacts in mind give themselves access to new market, substantially increase profit and enjoy competitive advantages over those marketing non-environmentally responsible
In a clear understanding of these differences lies the key to understanding the broad range of theories, agendas, programs, regulations, technologies, and techniques that are confusingly put together under the mantle of ‘sustainable building.’ In its most general sense, ‘green building’ is a label for the process of design and construction which aims to produce buildings that are less damaging to the environment—and the people that use them—than most buildings currently built today. These buildings must be measurably less damaging in significant ways of course, and unfortunately there are many examples of ‘green’ buildings that purport to be less damaging without supporting measurements, or that otherwise claim to be have integrated environmental concerns without addressing the most significant issues. ‘Sustainable building,’ however, refers more precisely to the goal of designing and constructing buildings that have no net impact on the environment, such that a total built environment composed of similar buildings could co-exist with the world’s ecological balance
It is difficult to determine which material is the most sustainable between the three construction materials because all of them have different advantages as seen in the body of this chapter. By looking at the comparison between wood, steel and masonry to see witch material is more sustainable one can clearly see that wood has the most green features and will probably be the most eco friendly construction material of the three. The construction material with the second most green features is masonry and with the third most is steel. One can also rate the appropriateness of the construction material green features in a country but will not be included in this study. The best way to go about picking a construction material is to plan ahead because planning can also contribute to an eco friendly
Sustainable construction is the creation and responsible management of a healthy built environment based on resource efficient and ecological principles. Creating and operating buildings are matters that account for about 40% of global annual energy consumption, and therefore, an important aspect of sustainable construction is to become market responsive, and integrate the supply chain while minimizing waste. The whole process of construction would therefore engage all stakeholders of the construction industry. Concerns and Difficulties of Sustainable Construction Three issues are of utmost concern while abiding by the philosophy of sustainable construction: • Different building projects are made for different purposes. Depending on the purpose of the building, the actual effect of the sustainability practices adopted may vary at different stages of construction and use.
2.0 Chapter 2 2.1 Sustainable Development in Construction 2.1.1 Definition Sustainable development is development that meets the needs of the present without compromising the ability of future generations to meet their own needs (McNeill, 2000). Also, a sustainable development should decrease recent levels of consumption of energy and resources and making of waste in order not to damage the natural systems which future generations would rely on to provide them with resources, take in their waste and provide safety and more healthful living conditions. 2.1.2 Importance of Sustainable Development Sustainable development consists passing on to future generations a stockpile of ‘capital’ that is at least as big as the one that our individual
