Naturally designed air convention should be incorporated into the design so that summer heat can be released through roof vents without the use of mechanical systems and human and radiant heat retained in the winter. The goal is to limit and if possible, eliminate the use of electric or fossil fuel operated systems to maintain acceptable temperatures. For design purposes, the contractor shall consider an acceptable temperature range of 18° C (64.4°F) to 28°C (82.4° F).Can anyone tell me that which kind of heating and cooling system is required for above, to use less or eliminate the electrical and mechanical system and maintain the temperature between 18° C (64.4°F) to 28°C (82.4° F)?
It can be done by first insulating the building really well then drawing air into the building through water cooler heat exchangers passing the air through the occupied spaces and up out of the building through chimneys to draw it out. I don't think it is practical because environmental codes require a minimum air flow which you may not be able to achieve under all conditions. You may be able to achieve this in a cave. Either way is really expensive. I think this may depend on what country it's in and their codes..
