However, in buildings of unusually tight construction, you must provide additional fresh air. Unusually tight construction is defined as construction where: a) Walls and ceilings exposed to the outside atmosphere have a continuous water vapor retarder with a rating of one perm (6×10-11kg per pa-sec-m ) or less with openings gasket or sealed and... - Page 9 4. Compare the maximum BTU/hr the space can support with the actual amount of BTU/hr used BTU/hr (maximum the space can support) BTU/hr (actual amount of BTU/hr used) Example : 51,200 BTU/hr (maximum the space can support) 56,000 BTU/hr (actual amount of BTU/hr used) The space in the above example is a confined space because the actual BTU/hr used is more than the maximum BTU/hr the space can support.
