I looked at the Septic permit that we had looked at yesterday and I have attached if for your reference. The system design states it was designed at750 gallons but the final inspection states that it is 1000 gallons as installed. I assume this means they decided to increase the size upon installation. I also assume this means we are fine with that size for the 3 bedroom home that we are creating. Agreed...however, your current plans indicate beds or sofa beds in both the new office and downstairs family room. lf those remain as shown on the plans and/or if there is a closet shown in eitherof these rooms, we have no choice but to callthose "bedrooms" too, which mayaffect sizing requirements of the septic system. Regarding the light requirements I wanted to share the numbers that I have calculated. First off, the existing basement did not meet the natural lighting requirements. It was 446sf which would require 35.7sf of glazing. I calculate that the existing glazing adds up to 28.6sf. I wonder if this allows for some grandfathering. The proposed changes to the basement decrease the size of it as we are adding a bathroom. The new size is 348s1 which includes the stair landing but not the stair. ( I should have asked you how you would calculate the area of that room. Would you include the landing or not?) Based on that size, we would need 27.8sf of glazíng. I have 16.7sf with the windows direct to the outside, but if I add the windows to the vestibule, I get a total of 34.4sf which exceeds the requirement. 1 pofiion from the remainder of the floor assem- blv. 4. Wood floor assemblies using dimension lumber or structural composite lumber equal to or greater than 2-inch by lO-inch (50.8 mm by 254 mm) nominal dimension, or other approved floor assemblies dem- onstr ating equivalent fire performance. .& During a fire unprotected floor assemblies of light- weight construction have a short time gap between untenable conditions and the structural collapse of the floor assembly. Section R302.1.3 requires protection to floors of light-weight construction that will provide the occupants additional time for self-evacuation and safety for fire fighters performing search and rescue. This section requires all floor assemblies, not fire rated, to be protected on the underside with 1/r-inch gypsum board, 5/u-inch wood structural panels or equivalent. This will apply mainly to floor assemblies located over nonsprinklered areas such as unfinished basements and crawl spaces for storage or containing fuel-fired appliances. There are four exceptions pro- vided that specify where the protection is not required' Exception 1 permits floor assemblies above any space protected by an automatic sprinkler system to be exempt from the application of the protective mem- brane to the underside of the floor-framing members. Section R313 requires an automatic residential fire sprinkler system (ARFSS) for new construction and the floor assemblies at each story will have the space below protected; therefore, Section R302.1.3 is not required. For crawl spaces used for storage or contain- ing fuel-fired appliances and alterations or additions to existing buildings that are not provided with an ARFSS' existing buildings that are not provided with an AFRSS, this exception will permit deletion of the protective membrane if the space is protected by an AFRSS in accordance with Section P2904, NFPA 13 D or other approved methods.'Èxception 2 exempts floor assemblies over crawl spaces, unless the crawl space contains fuel-fired appliances or is intended for storage' However, Excep- tion 1 may be used for crawl spaces intended for stor- age or containing fuel-fired appliances. Exception 3 prescribes an allowable area where the protective membrane may be omitted' Exception 4 permits floor framing of sawn lumber or structuial composite lumber equal to or greater than 2 x 10 nominal dimension to be exempt from the appli- cation of the protective membrane to the underside of the floor-framing members. The basis for this excep' tion is that tests conducted of floor framing constructed of 2 x 10 lumber and loaded to 50 percent of full design load showed that the assemblies provided adequate time for occupants to self-evacuate and safety for fire fighters performing search and reuse. BUILDING PLANNING R302.14 Combustible insulation clearance. Combustible insulation shall be separated not less than 3 inches (76 mrn) from recessed luminaires, fan motors and other heat-produc- ing devices. Excepfion: Where heat-producing devices ue listed for lesser clearances, combustible insulation complying with the listing requirements shall be separated in accordance with the conditions stipulated in the listing' Recessed luminaires installed in the building thermal eruvelope shall meet the requirements of Section Nl 102'4.5 of this code. "l The minimum clearance required between combusti- ble insulation and light fixtures, fan motors, etc., mini- mizes the chance of accidental ignition of the insulation. lf a healproducing device is listed for less than the minimum clearance specified in this section and all conditions of the listing are satisfied, the reduced clearance would apply. SECT'ION R3O3 LIGI.IT, VENTILAT¡ON AND I.IEATING R303.1 Elabítable rooms. Habitable tooms shall have an aggregate glazing area of not less than 8 percent of the floor area of such rooms. Natural ventilatiott shall be through win- dows, skylights, doors, louvers or other approved openings to the outdoor air. Such openings shall be provided with ready access or shall otherwise be readily controllable by the build- ing occupants. The openable area to the outdoors shall be not less than 4 percent of the floor area being ventilated. Exceptions: 1. The glazed areas need not be openable where the opening is not required by Section R310 and a whole-house mechanical ventilation system is installed in accordance with Section M1507. 2. The glazed areas need not be installed in rooms where Exception I is satisfied and artificial light is provided that is capable of producing afl aYerage illumination of 6 footcandles (65 lux) over the arca of the room at a height of 30 inches (7 62 mm) above the floor level. 3. Use of sunroom and patio covers, as defined in Sec- tion R202, shall be peimitted for naturalventilationif in excess of 40 percenr of the exterior sunroom wails are open, or are enclosed only by insect screening' * All habitable rooms are to be constructed with an aggregate glazing area of not less than B percent of the floır area. The code does not require the glazed area to be openable. This section also provides the stan- dard of natural ventilation for all habitable rooms' Openings to the outdoor air, such as doors, windows and louvers, provide natural ventilation' The openable area must be not less than 4 percent of the floor area being ventilatcd. This section does not, however, state 3-64 2015 INTERNATIONAL RESIDENTIAL CODE@ COMMENI.ABY n 2 to Section R303.1 allows to be com rooms ava s capa ng an average of 6 footcandles (65 lux) over the room at a height of 30 inches (762 mm) above the floor level and where a whole-house mechanicalventilation system complying with Exception 1 to Sectíon R303.1 is installed. Exception 3 allows for the openings in a sunroom (those in which more than 40 percent of the exterior sunroom walls is open) to provide naiural ventilation when the exterior walls of the sunroom are open. lnsect screening for these seasonal rooms is also acceptable to make use of this exception. Various handbooks are available from lighting man- ufacturers for calculating the required illumination. R303.2 ,{djoining rooÍns. For the purpose of determining light and ventilation requirements, any room shall be consid- ered to be a portion of an adjoining room where not less than one-half of the area of the common wall is open and unob- structed and provides an opening ofnot less than one-tenth of or intend that the doors, windows or openings actually be constantly open. The intent is that they be main- tained in an operable condition so that they are avail- able for use at the discretion of the occupant. ln addition to the natural ventilation provisions of this sec- tion, a whole-house mechanical ventilatíon system may be required in accordance with the provisions of Section R303.4. Although the glazed area may be operable, Excep- tion 1 permits the glazed area for all openings, except the ones required for emergency escape and rescue, to be fixed or "not openable" when a whole-house mechanical ventilaiion system is installed in accor- dance with Section M1507. BUILDING PLANNlNG the floor area of the interior room and not less than25 square feet (23 rrt). Exception: Openings required for light or ventilation shall be permitted to open into a sunroom with thermal isolation or a patio cover, provided that there is an openable area between the adjoining room and the sunroom or patio cover of not less than one-tenth of the floor area of the interior room and not less than 2O square feet (2 m'¡. The minimum openable arca to the outdoors shall be based upon the total floor area being ventilated. * Where rooms do not have access to an exterior wall to satisfy light and ventilation requirements, they may be considered as part of an adjoining room if they are open to that room as shown in Commentary Figure R303.2. The exception deals with a very common circum- stance, especially in residential construction. As long as the sunroom addition is large enough and is ther- mally isolated, the building owner need not move openings for lighting and/or ventilation when installing an addition that meets the definition of "Sunroom addi- tion." R303.3 Bathrooms. Bathrooms, water closet compafiments and other similar rooms shall be provided with aggregate glaz- ing area in windows of not less than 3 square feet (0.3 m'), one- half of which must be openable. Exception: The glazed areas shall not be required where artificial light and a local exhaust system are provided. The minimum local exhaust rates shall be determined in accordance with Section M1507. Exhaust air from the space shall be exhausted directly to the outdoors. .i.
