Hello, we have a project where the spaces are naturally ventilated and heated by radiators.may i know whether i should comply under Optional method for naturally conditioned spaces. Section 5.3 of 55 -2004 says :
The space may be provided with a heating system, but this optional method does not apply when the heating system is in operation. Does this mean do i have to show compliance for summer months only or do i need to apply a different comfort settings comply under mechanical conditioned category during the heating period.
