Need advice on Heat loss & Heat gain calculation programs

Edward A. (Ed) Carery

I am looking for some advice on the pros & cons of the newest and best heat loss & gain computer programs. I presently have an old program from an equip mfgr, but it is not up to present day standards.

I am concerned with easy to use features and professional print out results and am willing to pay more for a better product.

As part of the program I would like the ability do as detailed a loss/gain calc as I choose and to project estimated energy consumption for all fuels to be able to plug in the per unit costs (oil/gallons, gas/therms etc.) and compare estimated op costs of elect, heat pump, oil, nat gas, lp gas, etc.

Entire system design and layout is a benefit but not as important a feature. Most calcs will probably be used to make comparisons of fuel consumption for retrofit equipment to existing distribution system.

Thanks
