Chapter 15-07 International Energy Conservation Code

The following amendments are hereby made to the International Energy Conservation Code:

(A) Chapter 1 is hereby deleted. Refer to BMC Chapter 15-03 for administrative requirements.

(B) Subsection 302, Design conditions, is hereby amended to read as follows:

Section 302 Design conditions. The outdoor and interior design conditions shall be as established in Tables 302.1 and 302.2 herein below.

TABLE 302.1
Outdoor Design Conditions

Elevation (feet)		5344
Latitude (degrees north)		40
Winter	Heating 99% dry bulb (degrees)	1
	Cooling 1% dry bulb (degrees)	91
Summer	Coincident wet bulb	59
	Design grains (50% RH)	-41
	Daily Range (DR)	High (H)
Relative Humidity (winter and summer)		50%

TABLE 302.2
Interior Design Conditions

Heating (degrees)		70
Cooling (degrees)		75
Heating Temperature Difference (HTD)		69
Cooling Temperature Difference (CTD)		16
Cooling Load Temperature Difference (CLTD)		21.0
Altitude Correction Factor (ACF)		0.84
Moisture Content		68.2
Air Density		0.063
Wind Velocity Values	Heating (mph)	15
	Cooling (mph)	7.5
Solar Heat Gain Coefficient (SHGC): While not required per Table 402.1.1 of the IECC, the SHGC is still required data for Manual J. SHGC should be taken directly from sticker on glass. If not known, either use default as per Table 102.2(3) of the IECC or equation SHGC = 0.87 x SC (shading coefficient) under A4-5 of Manual J.
