Question

what are the ancient practices to increase the energy efficiency?

Answer 1

Energy efficiency can enhance human health by reducing greenhouse gas emissions, improving outdoor air quality and decreasing acid rain. The energy needed to run commercial and industrial buildings in the United States produces 19 percent of U.S. carbon dioxide emissions, 12 percent of nitrogen oxides, and 25 percent of sulfur dioxide, at a cost of $110 billion a year.
The healthcare sector is in need of cost effective solutions to address the rising cost of energy and the health implications of energy use. Once a facility has developed an energy baseline by tracking and measuring its energy use, it can begin to zero in on key areas of inefficiency and review potential energy reduction strategies with an eye for what will work given the financial resources of the organization. Improving the efficiency of energy end uses reduces both energy cost and greenhouse gas emissions – and is often called ‘demand-side management’.
