Hawaii County Energy Code Bill <br /> Annotated Draft <br /> 11127119 <br /> similar to that of a residential building-,the requirements in Sections R401.2.1 <br /> Tropical Zone shall be permitted to be used." <br /> Comments: <br /> A. Extends Tropical Zone provisions for small commercial projects with <br /> construction similar to that of a residential building. <br /> B. Larger commercial buildings or commercial buildings with significant <br /> cooling loads may have a similar configuration to a residential use but <br /> due to scale their use intensity cannot be compared to a single-family or <br /> duplex dwelling use. Limits would make it easier for the code official to <br /> be consistent in their acceptance of this exception. <br /> C. The intent to allow for a tropical zone provision as noted in comment A <br /> was for smaller residential type commercial projects. 2500 sf is tied to the <br /> square footage limits defined in the POINTS option of 8407, Furthermore, <br /> the 4-ton cooling limit was defined based on the State of Hawai`i <br /> Department of Health Administrative Rules Title 11-39. Section 11-39-6 <br /> provides an exemption to the requirement for a "Form-1 Permit"for a <br /> 4.25 ton cooling system. <br /> (8) Subsection C402.1.1 of the International Energy Conservation Code is amended to <br /> read as follows: <br /> "C402.1.1 Low-energy use buildings. The following low-energy use buildings, or <br /> portions thereof separated from the remainder of the building by building thermal <br /> envelope assemblies complying with this section, shall be exempt from the building <br /> thermal envelope provisions of Section C402. <br /> 1. Those with a peak design rate of energy usage less than 3.4 Btu/h•ft2 (10.7 <br /> W/m2) or 1.0 watt per square foot(10.7 W/m2) of floor area for space <br /> conditioning purposes. <br /> 2. [Those that do iiet eofilaift eonditioned spoee] Unconditioned space that does <br /> not contain occupiable space and/or habitable space. <br /> 3. Greenhouses. <br /> 4. Open park pavilions where there is no enclosed space." <br /> Comments: <br /> A. State Justification: The amended language ensures that habitable space, <br /> even if unconditioned, will be covered by the provisions of the energy code <br /> to increase occupant comfort and reduce the possibility of installing air <br /> conditioning in the future. <br /> See State ECC at§3-181.1-8, HAR, Kauai County at§12-6.4(11), KCC, <br /> and Maui County at§16.168.C402.1.1, MCC. <br /> 7 <br />
