Addition Alone
Any addition --that is, the sum of all new
conditioned spaces and associated new exterior
walls, ceilings, and floors within the building --
may be shown to meet the energy budget as .a
separate entity. 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. In.this method, total
glazing area in the addition is limited to 16% of
