Comparison on Three Approved Method of Energy Savings

Approved energy savings accurately is the key to the success of energy performance contracting(EPC) . Using the manual calculation and software simulation to the approved energy savings is the most energy-saving units' method used, but the accuracy of its approved is unknown. A government office building in Beijing in energy-saving projects of "Eleventh Five-Year Plan" for example, diagnosis its current situation of energy consumption, use the manual calculation method, DeST software simulation, change degree-day method to check and ratify its energy savings. Though its data analysis and horizontal and vertical comparison, provide a reference for the accuracy and stability of the three approved methods.
