V Exterior Windows & Doors 606.1 Max. 0.3 cfm/sq.ft. window area; .5 cfm/sq.ft. door area. {./' Sole & Top Plates 606.1 Sole plates and penetrations through top plates of exterior walls must be sealed. V Recessed Lighting 606.1 Type IC rated with no penetrations (two altemativas allowed). - Multistory Houses 606.1 Air barrier on perimeter of floor cavity between floors. - Exhaust Fans 606.1 Exhaust fans vented to unconditioned space shall have dampers, except for combustion devices with integral exhaust - ductwork. Combustion Heating 606.1 Combustion space and water heating systems must be provided with outside combustion alr, except for direct vent - appliances. Water Heaters 612.1 Comply with efficiency raquirements in Table 612.1.ABC.3.2. Switch or clearty markad circuil breaker electric or cutoff - (gas) must be provided. External or built.in heat trap required for vertical pipe risers. SWimming Pools & Spas 612.1 Spas & heated pools must have covers (except solar heated). Noncommercial pools must have a pump timer. Gas spa & - pool heaters must have minimum thermal efficiency of 78%. Hot Water Pipes 612.1 Insulation is required for hot water Circulating systems (including heat recovery units). - Shower Heada 612.1 Water flow must be restricted to no more than 2.5 gallons per minute at 80 pslg. - HVAC Duct Construction, 610.1 All ducts, fittings. mechanicaJ equipment and plenum chambers shall be mechanically attached, sealed, insulated and - Insulation & Installation installed in accordance with the criteria of Section 610.1. Ducts In attics must be insulated to a minimum of A-B. HVAC Controls 607.t Separate readily accessible manual or automatic thermostat for each system. - GENERAL DIRECTIONS: 1. On Table 6C-llndicate the R-value of the insulation being added to each component and the efficiency levels of the equipment being installed. All R-values and efficiencies Installed must meet or exceed the minimum values listed. Components and equipment nellher being added nor renovated may be left blank. 2. ADDITIONS DNLY. Determine the percentage of new glass to conditioned floor area in the addllion as fOllOWS. Total the areas of all glass windows, sliding glass doors and glass door panels. Oouble the area of all nonvertlcal roof glass and add II to the previous total. When glass in existing exterior walls is being removed or enclosed by the addition, an amount equal to the total area of this glass may be subtracted from the total glass area. Divide the adjusted gfass area total by the conditioned floor area of the addition. Mulliply by 100 to get the percent. Rnd the largest glass percentage under which your calculated percentage falls on Table 6C-2. Prescriptives are given by the type of glass (single or double pane) and the overhang (OH) paired with a solar heat gain coefficient (SHGC). For a given glass type and overhang, the minimum solar heat gain coefficient allowed is specified. Actual glass windows and doors previously In the exterior walls of the house nd being reinstalled in the addition do not have to comply with the ovemang and solar heat gain coefficient reqUirements on Table 6C-2. All new glass in the addition must meet the reqUirement for one of the options in the glass percentage category you indicated. The ovemang (OH) distance is measured perpendicularly from the face of the giass to a point directly under the outermost edge of the overhang. 3. RENOVATIONS ONLY. Replacament glass needs to meet the following requirements. Any glass type and solar heat gain coefficient may be used for glass areas which are under at least a 2-foot overhang and whose lowest edge does not extend further than B feet from the overhang. Glass areas being renovated that do not meet this criteria must be either single-pane tinted, dOUble-pane clear or doubie.pane tinted. 4. BUILDING SYSTEMS. Comply when new system is installed for system Installed. 5.
