(B) Exceptions. (i) Design load calculations need not be submitted for new, individually permitted cooling systems of ]ess than 65 000 Btu/hr capacity that provide less than 37 Btu/hr of installed capacityper square foot of conditioned floor area. (ii) Design load calculations need not be submitted when existing cooling equipment is replaced with equipment of equal or less capacity." SECTION 13. Section 5-29.3.(g) of the Hawaii County Code 1983 (1995 Edition) relating to Materials and Construction is hereby amended so that Table 9-1 relating to Minimum Pipe Insulation reads as follows: Table 9-1 Minimum Pipe Insulation (Inches).
