Energy TAC

IECC-R Code Change No.	IECC-R Section	Change Summary b/t 2015 IECC-R and 2018 IECC-R	Change Summary b/t 2017 FEC-R and 2018 IECC-R	Staff comments	
					
CE248-16, Part II	R406.3 (N1106.3)	Modifies text of Section R406.3 (N1106.3) Energy Rating Index. Proposal provides an exception for energy used to recharge or refuel a vehicle that is used for on-road (and off-site) transportation purposes. This exception is limited to vehicles that are only used for off-site purposes that are obtaining their energy through the building energy infrastructure.

Cost Impact: Will not increase the cost of construction.
This does not change the requirements for total building performance, but clarifies what is to be excluded from scope of this section. Therefore, it will not increase the cost of construction.
	Same as change between 2015 IECC-R and 2018 IECC-R

RE5-16	R202 (IRC N1101.6)	Modifies text of Section R202 “(N1101.6) HIGH-EFFICACY LAMPS”. This proposal clarifies the definition to include LED lamps and other lamp technologies that may be used

Cost Impact: Will not increase the cost of construction.
This proposal only clarifies the definition and does not change any code requirements.

Cost Impact: Will not increase the cost of construction. This proposal only clarifies the intent of the code. There is no additional materials or labor costs associated as this work is what the current code intends.

Per reasoning, the intent of the code is that whatever the finish surface, penetrations must be sealed to it. Per committee, not all finishes are drywall so this is an appropriate change.

Cost Impact: Will not increase the cost of construction. This proposal only clarifies the code provision for sealing. As this is only a clarification, there is no additional cost associated with

RE71-16	Table R402.4.1.1 (IRC Table N1102.4.1.1)	Modifies text of table R402.4.1.1 (N1102.4.1.1) “AIR BARRIER AND INSULATION INSTALLATION”. Proposal changes HVAC register boots section, such that forced air passes through a supply boot a portion of that air is directed into building cavities the boot penetrates.

Cost Impact: Will increase the cost of construction. There is a minimal cost impact associated with this proposal. The duct system is already being sealed with mastic to meet the duct leakage requirements of the code and the additional mastic installation needed to seal a supply boot to the subfloor is small.

“SPECIFICATIONS FOR THE STANDARD REFERENCE AND PROPOSED DESIGNS”.  This change simply corrects the equation for the energy calculation of the mechanical ventilation system. There is no effect on
system cost.

Cost Impact: Will not increase the cost of construction.
