Jakarta can save hundreds of millions of kilowatt-hours (kWh) of electricity per year by reducing energy use in the capital's commercial building sector, says a member of Indonesia's Green Building Council (GBCI).
The deputy chair of the council, Rana Yusuf Nasir, said recently that businesses could reduce 7 to 11 percent of their energy use by tuning up appliances, downsizing and upgrading performances with no extra cost. He also added that energy use could be reduced by 17 to 30 percent at a medium cost.
In an analysis carried out in 2004, Rana said that Jakarta had around 10 million square meters of commercial building that consumed around 2,500 million kWh per year. By saving 15 percent in energy use, 375 million kWh per year can be saved.
He added that it would also reduce CO2 emissions by 303,720 tons per year or an equivalent of having 475,000 trees.
Naning S. Adiningsih Adiwoso, chairwoman of the council said the essence of green buildings was efficiency.
"Green buildings have to use water and air conditioning efficiently. Such buildings should use environmentally friendly materials. It would be better if they created zero carbon by using biodegradable, recyclable, and reusable materials," she said.
