Hawaii County Energy Code Bill <br /> Annotated Draft <br /> 11127119 <br /> Comment: <br /> In the International Energy Conservation Code the blower door test is a way to <br /> avoid tested and labeled fenestration. This would allow for site built windows <br /> and other high performance custom solutions. <br /> (14) A new subsection 0403.2.4.2.4 is added to the International Energy Conservation <br /> Code to read as follows: <br /> "C403.2.4.2.4 Door switches. Opaque and Mass doors opening to the outdoors in <br /> hotel and motel sleeping units, guest suites, and time-share condominiums, shall be <br /> provided with controls that disable the mechanical cooling or reset the cooling <br /> setpoint to 90°F or greater within five minutes of the door opening. Mechanical <br /> cooling may remain enabled if the outdoor air temperature is below the space <br /> temperature." <br /> Comment: <br /> State Justification: This change will require automatic controls that reset the <br /> cooling system temperature in a hotel and motel sleeping unit, guest suites and <br /> time share condominiums when doors to the outdoors are let open. A similar <br /> requirement is contained in the American Society of Heating and Air- <br /> Conditioning Engineers (ASHRAE) 90.1-2013 Section 6.5.10. Research indicates <br /> that there is a potential for significant savings when in-room energy management <br /> systems are employed. A study by Pacific Gas and Electric as well as research by <br /> Magnum Energy Solutions,found that key card energy control systems provided <br /> an estimated savings of 35% - 45%per room. Additionally,prior research <br /> conducted for the State of Hawai`i indicated that occupancy-based guest room <br /> controls could provide at least 5%savings for the entire hotel. <br /> A study conducted in 2002 by Jeff Stein of Taylor Engineering and created for the <br /> California Statewide Utility Codes and Standards Program estimated savings of <br /> almost 60%for operable windows andlor doors with switches versus operable <br /> windows andlor doors without switches. The full analysis is contained in the <br /> "Analyses and Proposal of Hawaii Amendments to the 2015 International Energy <br /> Conservation Code.
