DESIGN STANDARD OF ENERGY CONSERVATION FOR BUILDING HVAC 1 SYSTEM – A SIMPLIFIED METHOD OF CHILLER CAPACITY ESTIMATION 2 BASED ON BUILDING ENVELOPE ENERGY CONSERVATION INDEX IN 3

The research developed maximum chiller cooling capacity predicting equations with building shape factor and the ENVLOAD index which is now the building envelope energy conservation design control factor in Taiwan. The models are established base on numerous DOE-2.2 simulations and statistical multi-regression techniques. Totally, there were 21 sets of predicting models be built with a satisfactory R2 of 0.8 to 0.9.
