Abstract :

Due to increasing demand for high-energy buildings, technical solutions are required to use it optimally and minimum energy consumption. Thus, investigation on solution that can decrease the amount of energy and as a result GHG emissions following is needed. One of the solution is based on underground energy storage that used mainly 24-hour. Heat is stored during day and extracted during night. Heating and cooling demand of the building is not reduced, but using an underground storage can decrease the amount of energy that has to be bought and Environmental degradation. In this investigate, the hospital considered in Tehran City, representing high energy performance buildings, heat transfer and fluid calculation for heat and cold storage is simulated with MATLAB program for underground pipes. Also heating and cooling load of the building calculated with HAP4.5 program and results are imported to MATLAB program, then system volume, ground response and reducing carbon dioxide emissions are studied. The result of this survey showed that, by using 24-hour storage system during a year, which has 15 line of steel pipeswith 600 meters length and nominal diameter of 3 inches where placed in 3 meters ground depth, 67% of heating load and 34% of cooling load can be met and CO2 emissions reduced 127 ton per annum.
