Effect of cost related parameters on optimization of Zero Net Energy Buildings

Zero Net Energy Buildings (ZNEB) are most opted for effective energy conservation measures. The major milestone in building ZNEB is the large number of parameters on which energy consumption depends. This paper studies the effect of cost related parameters on optimization of ZNEB. Effect of cost of appliances on the optimized parameters is investigated. Opensource softwares are explored for the simulation studies and extended modules are built for integrating retail tariffs/OpenEI to the engines. Simulations are carried out with different utility rates and tariff system, and a comparison is made. ZNEB potential in developing countries like India is further discussed and observations are presented.
