Computer programs that can be utilized for thorough analysis of a radiant panel heating and cooling HVAC system have not been developed. Some computer programs provide a rigorous analysis of energy transfer but have a limited selection of HVAC system alternatives. Other computer programs are based on a convective energy transfer model but have a comprehensive selection of HVAC system alternatives for simulation. First the hypothesis, a convective model can simulate the energy consumption of a radiant panel heating and cooling system, was tested. Software modifications were made to an existing computer program that performs a rigorous energy balance with all forms of energy transfer so that convective and radiant systems could be compared. System operation and performance were considered for a standard room. After concluding the convective model was adequate within a range of limits, software modifications were made to a second computer program that had a comprehensive selection of HVAC system alternatives adding the radiant panel system. Energy consumption of various HVAC systems were then compared. Finally, life cycle cost analyses were completed for a standardized hospital for various geographic locations; conclusions were that radiant panel heating and cooling systems can be justified on a life cycle cost basis.
