Sustainable Development
Use of Resources
to meet our
needs without
depriving the
resources for
future
generations

WHAT IS A SUSTAINABLE BUILDING?
Uses key resources more efficiently – energy, water, materials and land
Reduces ecological loading – greenhouse gases, ozone-depleting substances, wastes
Creates healthier environments for people to live, work and learn
Has lower overall lifecycle costs

ENERGY AUDIT
‘Energy Audit’ :inspection, survey and analysis of energy flows for energy conservation in a building, process or system to reduce the amount of energy input into the system without negatively affecting the output(s)
Industry based:
Minimize energy costs
Reduce environmental effects
Benchmark: unexpected or excessive costs

The type of Energy Audit to be performed depends on:
Function and type of industry
Depth to which final audit is needed
Potential and magnitude of cost reduction desired
Thus Energy Audit can be classified into the following two types
1. Preliminary Audit 2. Detailed Audit

IN SEARCH OF SOLUTIONS..
To reduce carbon footprints

WHAT IS CARBON FOOTPRINT
Measure of the impact our activities have on the environment, and in particular climate change.
Relates to the amount of GHG’s produced in our day-to-day lives.

“Warming of the climate system is unequivocal, as is now evident from increases in global average air and ocean temperatures, melting of snow and ice, and rising sea level.”
