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. Recessed Lighting 606.1 Type IC rated with no penetrations (two altematives allowed). /LH Multistory Houses 606.1 Air barrier on perimeter of floor cavity between floors. Ali Exhaust Fans 606.1 Exhaust fans vented to unconditioned space shall have dampers, except for combustion devices with integral exhaust 4 ductwork. is Combustion Heating 606.1 Combustion space and water heating systems must be provided with outside combustion air, except for direct vent appliances. A/ Water Heaters 612.1 Comply with efficiency requirements in Table 612.1.ABC.3.2. Switch or clearly marked circuit breaker electric or cutoff y (gas) must be provided. Extemal 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 %. t, ill Hot Water Pipes 612.1 Insulation is required for hot water circulating systems (including heat recovery units). ,cli Shower Heads 612.1 Water flow must be restricted to no more than 2.5 gallons per minute at 80 psig. HVAC Duct Construction, 610.1 All ducts, fittings, mechanical equipment and plenum chambers shall be mechanically attached, sealed, insulated and A Insulation & Installation installed in accordance with the criteria of Section 610.1. Ducts in attics must be insulated to a minimum of R -6. 17 HVAC Controls 607.1 Separate readily accessible manual or automatic thermostat for each system. Z GENERAL DIRECTIONS: 1. On Table 6C -1 indicate 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 neither being added nor renovated may be left blank. 2. ADDITIONS ONLY. Determine the percentage of new glass to conditioned floor area in the addition as follows. Total the areas of all glass windows, sliding glass doors and glass door panels. Double the area of all nonvertical root glass and add It 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 glass area total by the conditioned floor area of the addition. Multiply by 100 to get the pecent. 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 housend being reinstalled In the addition do not have to comply with the overhang 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 overhang (OH) distance is measured perpendicularly from the face of the glass to a point directly under the outermost edge of the overhang. 3. RENOVATIONS ONLY. Replacement 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 8 feet from the overhang. Glass areas being renovated that do not meet this criteria must be either single -pane tinted, double -pane clear or double -pane tinted. 4. BUILDING SYSTEMS. Comply when new system is installed for system installed. 5. Complete the information requested on the top half of page 1. 6 Read 'Minimum Requirements for Small Additions and Renovations, Table 6C -3, and check all applicable items. 7.
