Green or sustainable buildings use key resources like energy, water, materials, and land more efficiently than conventional buildings.
Why shift to green buildings:
1.Address growing costs of distribution
2.Reduce rise an electricity and gas prices.
3.Help cut pollution from fossil fuels.
4.Improve quality of educational environment
5.improved work and living environments
Costs:
The majority of this cost is due to the increased architectural and engineering (A&E) design time, modeling costs.
Financial benefits:
energy and water savings, reduced waste, improved indoor environmental quality, greater employee comfort/productivity, reduced employee health costs and lower operations and maintenance costs.
Energy savings:green buildings use 30% less energy than conventional buildings.
-green buildings have reduced electricity purchases and secondarily from reduced peak energy demand.
Productivity and health
Residents of green buildings have reduced illness symptoms, reduced absenteeism and increases in perceived productivity.
-Generally improved thermal comfort and better ventilation.
-CO2 monitoring to ensure better performance of systems such as ventilation, heating and air conditioning.
