This procedure does not ' involve the existing structure, except to modify the internal gains within the approved computer performance method, and may be performed using either a special prescriptive package or the point system or any approved computer performance method. SPECIAL PACKAGE A An addition may be shown to comply with the Standards by meeting specific requirements of Package A for the climate zone in which it is located as stated in §2-5301(d)2C of the Standards. The Package A features which apply to additions include: Ceiling, wall, slab perimeter and raised floor insulation levels • Glazing U -Value • Shading . the added floor area. The net glazing area takes into account glazing "removed from the existing building because of the addition." Therefore, the maxiinwn glazing area is 16% of the addedfloor area plus the area of glass taken ow of existing exterior walls and ceilings tp rapke way joi the addition. Package A for additions does not limit the amount of glazing which may occur on any one orientation, nor does it require any, thermal mass. Another feature of this special Package A for additions is that electric resistance space and/or water heating may be installed.. All applicable mandatory measures still apply. POINT SYSTEM OR COMPUTER METHOD ANALYSIS OF ADDITION ALONE Any addition may be analyzed alone using either the point system or a computer method . The rules for doing this are the same as for showing compliance of any new building except that the internal heat gain in Btu/day may have to be entered according to the following formula (depending upon the computer method): These Package A requirements are listed in Tables 3-ZI to 3-ZI6 in Section 3.4.
