AT PRESENT, ENERGY CONSUMPTION FOR SPACE HEATING OF INDUSTRIAL BUILDINGS IS AN IMPORTANT AMOUNT OF THE TOTAL ENERGY BALANCE IN THE INDUSTRIAL COUNTRIES. SEVERAL ENERGY SAVING INVESTIGATIONS CARRIED OUT ON INDUSTRIAL PLANTS EMPHASIZED IMPORTANT INEFFICIENCIES IN SPACE HEATING.

THESE INEFFICIENCIES MAY BE REDUCED THROUGH A BETTER DESIGN OF THE "BUILDING-SYSTEMS". THIS INVESTIGATION AIMED TO DETERMINE CRITERIA BOTH FOR DESIGN OF NEW INDUSTRIAL BUILDINGS AND FOR RETROFIT ON EXISTING ONES.
