We are giving our best shot to utilize natural ventilation, heating and cooling for the 8 month target identified in the program, but finding it quite difficult in the shoulder seasons. For the four months with the switch on: Is this an equivelent amount of time during the year when no energy is being consumed? For example, the switch on for no more then about 2800 hours during the year, which is about 4 months of time, but the switch is turned on and off over the year, Does it need to be consecutive?
The intent of this credit is to limit the use of mechanical conditioning to a fraction a conventional building\'s use. The limited 2/3 of a year for passive operation was envisioned to be contigous months correlating to the seasons. Should you wish to claim credit equivalence for limited non-contiguous hours of operation, the committee feels these would need to be supply the following inforamtion: 1) Proof that the project is naturally ventilated for the maximum amount of time possible for its region and function. 2) Provide more information on the type of building and the hours of operation. It is recommended that you turn in a credit equivalence application with these two issues addressed. Applicable internationally.
