Buildings be it commercial or residential are the guzzlers of energy. In USA, the Green House Gas emissions majorly come from road transportation or the commercial and residential buildings. While road transportation accounts for 21.6% of CO2 emissions, the commercial and residential buildings account for 15.3 and 12% respectively. Combined together, road transportation and buildings are responsible for 60% of GHG emissions.
This is a very high percentage. Compared to road transportation, the buildings offer great energy savings potential. Mere preliminary audits of buildings can save about 20 to 30% of energy which is otherwise being used in buildings.
Many programs are going on to certify buildings as STAR rating systems or as Green buildings. Many of the these programs promote using renewable energy sources on roof tops to make these buildings earn more and more points. Net Zero buildings are also in vogue. But what we all are missing is the road transportation leading up to these buildings. The crisscrossing of cities for daily commute to office or the place of work guzzle up lots of energy.
Working from home or living close to the place of work can be one of the solution but many of times may not be at all practical. So that leaves us with very few options. Addressing and regulating energy usages in buildings need attention of the highest scale.
The building owners must resort to energy auditing to contribute their bit towards making the planet safe and secure for our future generations.
