MEESG -­ A total energy demand prediction and optimization program for architectural scheme design stage

In this research, a new energy-­saving design method and a design-­aided program  MEESG  (Most-­Energy-­Efficient-­Scheme-­Generator)  are  developed.  The program aims to aid energy-­saving design by means of  optimization  algorithms  at  a  very  early  design  stage,  when  the  building  shape  is  not  even determined  by  the  architects.  In  this  program,  a  simplified  prediction  model  BEFPM  (Building Energy  Demand  Fast  Prediction  Model)  is  established  to  simulate  the  building  total  energy demand  very  quickly.  Meanwhile,  by  introducing  Genetic  Algorithm  into  BEFPM,  from  shape  and envelope  parameters  to  HVAC  system  forms,  the  computer  can  automatically  generate  the  design parameters of the most energy efficient scheme(s).
