Abstract - The building industry is one of the major energy
consumers and emitters of Green House Gasses (GHG). It consumes 38% of the global energy; and this does not include the usage of other resources such as water. Globally, this has increased the crisis of global warming and has led to development of Green buildings. In the Sub Saharan Africa alone, 56% of energy used is by building operations. Green buildings are marketed as economical, resource efficient and environmentally friendly compared to the convectional buildings. This study investigated the extent of adoption of green building concepts in commercial buildings and the key challenges arising from their adoption with the aim of determining appropriate strategies for implementing them. The study was conducted through a survey method and used questionnaires, interviews, observations for data collection. It also reviewed documented data from available records including journals and books. The study revealed that large percentage of the building construction players and professionals involved in the recently sampled constructed commercial buildings in our country were aware of the green building concepts but only small percentage of the concepts had been incorporated in the buildings. In this paper a study is conducted which determine the main concepts involve in the construction of green buildings moreover the strategies are also discussed which can help to create awareness in between people regarding the benefits of green building and could be a step towards green building practice for the future world. Key Words : Greenhouse gases ,strategies ,commercial building
1. INTRODUCTION The building industry’s sustainability ethics is based on the principles of resource efficiency, health and productivity and realizing these principles involves an integrated approach in which a building project and its components are viewed on a full cycle basis. [6], ‘This ‘‘cradle to cradle’’ approach known as ‘green’ or ‘sustainable’ building, considers a building’s total economic and environmental impact and performance from material extraction and product manufacture to product transportation, building design and construction, operation and maintenance and building re use and disposal [6]. Green buildings use less energy, water and natural resources compared to the convectional buildings. They also © 2017, IRJET

create less waste and provide healthier living environment, further they incorporate features such as efficient use of water, energy efficient and eco-friendly environment. The buildings use renewable energy and recycled materials, embrace effective use of landscape and have improved indoor quality for health and comfort [19]. In the United States more than 30 states and regional programs promote some level of energy efficiency and environmental responsibility for the residential construction [13]. The green buildings have been marketed as economical and as alternatives to convectional buildings [10], and the total number of commercial green building commissioned has hit the 10,000th mark .In Canada more than 212 green buildings had been accredited since 2010 [1] whereas in India the green concept has taken root with two green rating systems namely Leadership in Energy and Environmental Design green rating system (LEED) and Green Rating for Integrated Habitat Assessment (GRIHA) already in use. In the developing world such as Africa, sustainable construction has not received sufficient attention despite being an important aspect of sustainable development (Adebayo, 2000). According to the World Bank Development report of 2009, only South Africa has an established Green Building Council (GBC) but this is slowly changing with Morocco, Mauritius and Egypt being in the process of establishing their councils [7]
2. Green Buildings Green building also known as green construction refers to a structure using a process that is environmentally responsible and resource-efficient throughout a building's life-cycle from sitting to design, construction, operation, maintenance, renovation, and demolition [6]. This requires close cooperation of the entire project stakeholders all project stages [24]. The Green Building practice expands and complements the classical building design concerns of economy, utility, durability, and comfort [23]. Although new technologies are constantly being developed to complement current practices in creating greener structures, the common objective is that green buildings are designed to reduce the overall impact of the built environment on human health and the natural environment by efficiently using energy, water and other resources , protecting occupants’ health and improving employee productivity and reducing waste, pollution and environmental degradation [23].
