        Simulation Period
        Select the start and end days for the simulation, or select a typical 
 period using the links on the Info panel:
         
        
            - Annual simulation 
 - all 365 days of the year.
 
            - Summer design week 
 - a week identified by the weather data translator as being the hottest 
 of the year.
 
            - Summer typical week 
 - a week identified by the weather data translator as being typical of 
 the summer.
 
            - All summer - simulate 
 the whole summer (as identified by the weather data translator).
 
            - Winter design week 
 - a week identified by the weather data translator as being the coldest 
 of the year.
 
            - Winter typical week 
 - a week identified by the weather data translator as being typical of 
 the winter.
 
            - All winter - simulate 
 the whole winter (as identified by the weather data translator).
 
        
         
        The above typical simulation periods are derived from the Statistics 
 data from the currently selected Hourly 
 weather data.
