But the energy source is decreasing very fast now-a-days, so by implementing green buildings throughout the world, we can reduce the conventional energy consumption and so by reducing pollution. In this paper an analysis has given to compare between Normal buildings and Green buildings and its economical analysis. Key words: Green buildings, Green materials, Sustainable energy, passive energy systems. 1. INTRODUCTION A Green Building, also known as a sustainable building, it is a structure that is designed, built, renovated, operated, or re- used in an ecological and resource efficient manner. To build a green building we have to consider the parameters such as sustainable site, water resources, energy & atmosphere, materials & resources and indoor environment quality. The key objective of this project is to develop a smart and sustainable building which will reduce our conventional energy consumption and increase renewable energy consumption. This will make our buildings eco-friendly. 2. PARAMETERS OF GREEN BUILDING There are some parameters which we have to observe for making a green building such as:  Sustainable site  Water resources  Energy and atmosphere  Materials and resources  Indoor environment quality 2.1 Sustainable site This building is connected to residential zone or neighbourhood with an average density of 10 units per acre net. And within half at least 10 basic needs such as restaurant, school, hospital, post office, it can also be within the range of 1 km from railway station and bus line which makes it use by building occupants. This helps in reducing land development impact from single occupants. It can also be within the range of 1 km from railway station and bus line which makes it use by building occupants. This helps in reducing land development impact from single occupants vehicle. Site interruptions owing construction should not exceed 40 feet from building parameters and 5 feet from roadway curve. The degraded habitat area are restored heavy grave and promote bio diversity. The building location and design is selected in such a way that minimises site interruption. The natural surroundings of green building provide straw connection between the built and natural environment and also minimises adverse impact on normal portion of the site. The progress area on site increases the natural processes of evaporation and filtration by eliminating storm water runoff while in progress area maximises the water runoff. Which enter develop soil erosion. In order to light pollution the interior laminar of the building maintain the majority of direct beam illumination within the building. The interior light should not exceed out through the windows. The exterior should be designed so that all sight and the building mount luminary produce maximum initial illumination. 2.1 Water resources The most effective method to minimise storm water runoff is to reduce in progress area. The vegetated roof of green building is designed in such a move that native plant on the roof eliminates the storm water runoff and contaminate which facilitate and cooling of the building. The waste water inventory develops onsite and this water can be used function that conventionally serves by portable water. This is done by storm water harvest and rain water treatment system. Green building possesses high fixtures and dry fixtures such as non water urinals which help to reduce waste water volume in the building by disturbing portable water only for specific application benefit entire community through lower range in taxes. The most effective
