Table G-4: DEFAULT FENESTRATION PRODUCT U -VALUES 'Metal includes any field -fabricated product with metal cladding. Non-metal framed manufactured fenestration products with metal cladding must add 0.04 to the listed U -value. Non -Metal frame types can include metal fasteners, hardware, and door thresholds. Thermal break product design characteristics are: a. The material used as the thermal break must have a thermal conductivity of not more than 3.6 Btu- inch/hr/ft2/0F, b. The thermal break must produce a gap of not less than 0.210", and C. All metal members of the fenestration product exposed to interior and exterior air must incorporate a thermal break meeting the criteria in (a) and (b) above. In addition, the fenestration product must be clearly labeled by the manufacturer that it qualifies as a thermally broken product in accordance with this standard. 2For all dual glazed fenestration products, adjust the listed U -values as follows: a. Subtract 0.05 for spacers of 7/16" or wider. b. Subtract 0.05 for products certified by the manufacturer as low -E glazing. .c.

G-52 July 1, 1999 Residential Manual In the summer months, the mass material can be cooled down at night by natural ventilation. During the daytime, the mass absorbs excess heat and helps keep down indoor air temperatures. If glazing is well shaded to keep out direct sunlight, the mass can substantially reduce or eliminate completely the need for mechanical cooling. The standards specify thermal mass materials as including, but not limited to: • Hard -surfaced slab floors • Masonry walls and fireplaces • Gypsum board walls and ceilings in excess of 1/2 inch thickness The physical 'properties of thermal mass materials are listed in Table G-12. Table G-13 lists recommendations on when it is appropriate to take credit for a particular mass material. The intent of these guidelines is to prevent taking thermal mass credit for floor materials that are likely to be covered with carpeting at the time of building occupancy. Building officials should allow flexibility for building designs that include radiant floor heating systems and/or that incorporate large areas of uncarpeted slabs in conjunction with south facing glazing as an integral component of deliberately designed passive solar structures.

Kitchen Lighting Construction Installing energy-efficient lamps and fixtures can reduce lighting energy costs without sacrificing the quality or quantity of light available. As indi- cated in Table 2-2, a 40 -watt standard fluorescent lamp is over four times as efficient as a 100 -watt standard incandescent lamp. The general lighting in kitchens must: • Have an efficacy of at least 40 lumenshvatt (see Table 2-2). • Provide a uniform pattern of lighting, such as a fixture in the center of the kitchen or around the perimeter (not a fixture in the comer). • Provide a light level sufficient for performing basic kitchen tasks such as preparing meals and washing dishes. • Be controlled on a readily accessible switch at an entrance to the kitchen (not in a cupboard or beside the kitchen sink). • Be switched independent of incandescent lighting. • Shall not contain medium -base incandescent Kitchen Lighting (Section lamp sockets.

Most halogen lamps are designed to produce a beam of directed light. Manufacturer's data typically list the "candlepower" intensity of that beam, rather than lumens (lumens measure total light output in all di- rections). 3 A new technology using infrared reflecting films on the halogen capsules has increased output up to 30 lumens/watt for some high wattage lamps. Efficacy of fluorescent lighting varies depending on lamp and ballast types. 2-48 July 1, 1999 Residential Manual • �i Kitchen Lighting Would one fluorescent light in a kitchen, Installed over the sink or under one.. cabinet, meet the: "general lighting" requirements? No. The general lighting must evenly light. the entire kitchen. Two examples of acceptable lighting configurations are (1) fluorescent lighting (or other light source. with at, least 404umens/watt) around the perimeter of the kitchen (under orover cabinets),. or (2) a fluorescent in the. center of: the .kitchen. If a customer asks me hot.to install fluorescent lights in their home, are there any other light sources 1 can use to meet the: kitchen lighting requirements? Yes, although they may not be readily available, there are products other than fluorescent- which meet the lighting requirements of the standards; Section 150(k). The two criteria for the kitchen and bathroom general lighting are (1) a lamp with an efficacy of 40 lumens/watt or more, and (2) the fixtures cannot contain a medium base incandescent lamp socket. Table 2-2 indicates the typical lumens/watt of several common products, some of which meet the required lumens/watt. Specifications from a product's manufacturer can also be used to verify that a product has at least 40 lumens/watt. Bathroom Lighting (Section g g ( ton Energy Code 150(k)2 - 3) 2. Each room containing a shower or bathtub shall have at least one luminaire with lamp(s) with an efficacy of 40 lumens per watt or greater.

ALTERNATIVE to Section 150(k)2.: A high efficacy luminaire need not be installed in a bathroom if* B. All luminaires permanently mounted to the residence providing outdoor lighting shall be installed with the following characteristics: (1) Luminaires with lamps with 40 lumens per watt or greater, or (2) Luminaires with lamps with an efficacy of less than 40 lumens per watt shall be equipped with a motion sensor. Note: When using this alternative for multiple bathrooms, after complying with B. for the first bathroom, each additional bathroom in which a high efficacy luminaire is not installed must comply with A. alone. 3. Luminaires installed to meet the 40 lumens per watt requirements of Section 150(k) 1. or 2. shall not contain medium base incandescent lamp sockets, and shall be on separate switches from any incandescent lighting. ' Bathroom Lighting Construction Each room with a shower or bathtub must have at least one luminaire with lamps with an efficacy of at least 40 lumens/watt. If there is more than one luminaire in the room, the high -efficacy luminaire must be switched at an entrance to the room. As an alternative, both of the following are re- quired: 1. A luminaire with 40 lumens/watt lamps must be installed in another room with utilitarian functions such as a laundry room, utility room or garage; and 2. All permanently mounted outside lighting must either be at least 40 lumens/watt or equipped with a motion sensor. When using this alternative for two or more rooms A. A luminaire with lamps with an efficacy with showers or bathtubs, compliance with item 1. of 40 lumens per watt or greater is above is sufficient for the second or third rooms installed in a utility room, laundry room, since the outside lighting is already in compliance or garage; and with item 2 above. Mandatory Measures July 1, 1999 2-49 Luminaires installed to meet the 40 lumens/watt requirements cannot contain medium base incan- descent lamp sockets, and must be on separate switches from incandescent lighting. Incandescent lighting fixtures recessed into insu- lated ceilings must be approved for zero -clearance insulation cover (IC -rated) in compliance with Section 150(k)4 (see below). Installing energy-efficient lamps and fixtures can reduce lighting energy costs without sacrificing the quality or quantity of light available. As indicated in Table 2-2, a 40 watt standard fluorescent lamp is over four times as efficient as a 100 watt standard incandescent lamp. Bathroom Lighting Inspection ., Each room with a shower or bathtub (no require- ment in a half -bath) must have at least one lumi- naire with lamps with an efficacy of at least 40 lu- mens/watt, which may be fluorescent or another efficient technology (see Table 2-2 above). When there is more than one luminaire in the room, the high -efficacy luminaire (greater than or equal to 40 lumens/watt) must be switched at an entrance to the room. As an alternative, both of the following are re- quired: 1. A luminaire with 40 lumens/watt lamps must be installed in a laundry room, utility room or garage; and 2. All permanently mounted outside lighting must either be at least 40 lumens/watt or equipped with a motion sensor.
