Impacts Of Construction on environment
Consume nearly 40% of raw materials. Consume 32% of total energy produced. Consume 17% of the fresh water. Consume 25% of global wood harvest. Responsible for Acid Rain. Generates
- 25-40% of municipal solid waste.- 50% of world CFC production.- 30% of world CO2 production.

“ A building designed toconserve resources andreduce negative impacts onthe environment – whether itis energy , water , buildingmaterials or land.
What is Green building?
![Page 5: Energy Conservation Through Green Buildings](https://reader030.fdocuments.in/reader030/viewer/2022032421/55a658811a28ab66308b485c/html5/thumbnails/5.jpg)
Green buildings are designed for -
•Efficiently using energy.
•Improving occupant health &productivity.
•Reducing waste, pollution etc.
Advantages Of Green Buildings

Various Energy Saving Concepts
![Page 7: Energy Conservation Through Green Buildings](https://reader030.fdocuments.in/reader030/viewer/2022032421/55a658811a28ab66308b485c/html5/thumbnails/7.jpg)
Fundamental Principles
Orientation. Energy efficiency.Waste and Toxics Reduction. Indoor environment quality enhancement. Materials and resource efficiency.
The fundamental principles should be kept in mindwhile designing a green building :

Orientation Of A Building
• Maximum daylight.
• Poly carbonated sheets.
• Glass frames withnanotechnology .

Solar Electricity Generation
![Page 10: Energy Conservation Through Green Buildings](https://reader030.fdocuments.in/reader030/viewer/2022032421/55a658811a28ab66308b485c/html5/thumbnails/10.jpg)
Solar Energy Utilization
It can be used for –
• Lighting• Cooling• Heating• Drying
• Cooking• Sensors in washrooms• Electronic Gadgets

Rain Gardens
Planted Depression .
Reduces Rain Run off.
Prevents Soil Erosion .
Prevents Pollution .

Deciduous trees
Helps in maintaining temperature inside building by keeping greener in summers and falling leaves in winters hence allowing sun glare to enter the building in winters but not in summers.e.g. Amaltas, champa etc.
Role of Landscaping

Green roof is a roof of abuilding that is partiallyor completely coveredwith vegetation.
Green Roofs

• Grow flowers and fruits.• Reduce heating and cooling.• Reduce storm water run off.• Filter pollutants. • Sound Insulation.
Green roofs are used to:

The water is conserved by harvesting and storing the rainwater. The water harvested may be used in two ways:1) Direct use2) Ground water recharge.
.
Rain Water Harvesting System
Direct use Ground Water Recharge
