Claim:
An environmental apparatus control system comprising: an apparatus configured to a residential environment; a demand collector configured to collect demands of changing said residential environments from residents present in said residential environment and to collect the total number of residents present in said residential environment on a regular basis, said demand including a first demand and a second demand which are opposed to each other; a project composer configured to determine a control project of controlling said apparatus based upon said demands; said control project including a first project of controlling said apparatus to change said residential environment in one direction, a second project of controlling said apparatus to change said residential environments in the opposite direction, and a neutral project of controlling said apparatus to maintain said residential environments; and an apparatus controller configured to control said apparatus in accordance with said control project; wherein said project composer is configured to have a first reference and a second reference each determined by a first proportion of a count of the first demands in said total number of the residents and a second proportion of a count of said second demand in said total number of the resident, said first reference and said second reference being different from each other, to obtain a current first proportion of the collected count of the first demands in said total number of the residents, and a current second proportion of the collected count of the second demands in said total number of the residents so as to give a current demand ratio, wherein said current demand ratio is a coordinate relationship of said current first proportion and said current second proportion, and to compare said current demand ratio with said first and second references so as to select one of said first, second, and neutral projects in accordance with a comparison result, wherein said first reference is defined by a predetermined first ratio, said predetermined first ratio being a coordinate relationship of the first proportion and the second proportion, and said second reference is defined by a predetermined second ratio, said predetermined second ratio being a coordinate relationship of the first proportion and the second proportion, and wherein said project composer is configured to select said first project when said current demand ratio is above said first reference, second project when said current demand ratio is below said second reference, and said neutral project when said current demand ratio is between said first reference and said second reference.
