(New)	Modifies text of Section C403.2.16 “Walk-in coolers and walk-in freezers”. Adds new text of TABLE C403.2.16.1(1)
“Walk-in Cooler and Freezer Display Doors Efficiency Requirements”, TABLE C403.2.16.1(2) “Walk-in Cooler and Freezer Non-Display Doors Efficiency Requirements”, TABLE C403.2.16.1(3) “Walk-in Cooler and Freezer Refrigeration Systems Efficiency Requirements”. Adds new Section C403.2.16.1 “Performance standards”. This proposal updates the energy code with the June 2017 performance requirements which were to take effect per Federal Regulations. Modified by Committee to January 1, 2020.  The code change was further modified by the Committee.  The Modification corrects the effective date.

Cost Impact: Will increase the cost of construction. It is likely that the new performance requirements will increase costs compared to the previous design requirements. However, the performance requirements may allow more technology and design flexibility for manufacturers such that they may reduce such costs.

CE132-16	C403.2.3	Modifies text of table C403.2.3(3) “MINIMUM E3FFICIENCY REQUIREMENTS: ELECTRICALLY OPERATED PACKAGED TERMINAL AIR CONDITIONERS, PACKAGED TERMINAL HEAT PUMPS, SINGLE-PACKAGE VERTICAL AIR CONDITIONERS, SINGLE VERTICAL HEAT PUMPS, ROOM AIR CONDITIONERS AND ROOM AIR-CONDITIONER HEAT PUMPS”.  As of June 1, 2014, the federal efficiency requirements values for room air conditioners have been increased. In addition, the efficiency metric has been changed from EER (Energy Efficiency Ratio) to CEER (Combined Energy Efficiency Ratio), which is a metric that accounts for energy used in the "active" and "standby" modes of operation.
This proposal updates the table to reflect the current federal minimum efficiency standards.

Cost Impact: Will increase the cost of construction. The cost of room air conditioners that meet the most recent (2014) minimum standards is higher than the cost of room air
conditioners that met the previous federal minimum standard.
The new room air conditioners are more energy efficient and will have lower operating costs than the air conditioners meeting the previous federal standard. According to a 2011 DOE analysis, the consumer median payback is between 2.1 and 10.1 years, depending on the product.

Proposal to address increase of the minimum efficiency of closed circuit axial fan cooling towers.  The code change was further modified by the Committee.  The Modification updates the table to match the ASHRAE table.

Cost Impact: Will not increase the cost of construction.
The impact of having to select more energy efficient models will have a negligible effect on the cost of construction.

This proposal ensures that the table reflects the current minimum federal standards and design requirements for residential products that may be used in commercial buildings

Cost Impact: Will increase the cost of construction. The boilers that meet the most recent federal efficiency standards and design requirements will have higher initial costs than the
boilers that met the previous federal standards. However, they will have lower annual energy costs than the products meeting the previous standards.

Deletes Section C403.4.3.2.1 “Fan motors not less than 7.5 hp”, C403.4.3.2.2 “Multiple-cell heat rejection equipment”. This proposal reduces the threshold where variable speed drives (VSD) are required for heat rejection fan systems. The fan threshold is reduced from 7.5 to 5 hp. It also revises the exceptions for variable frequency drives on tower fans and clarifies that the hp threshold applies to arrays of fans. For tower fans, the exception for climate zones 1 & 2 is eliminated.

Cost Impact: Will increase the cost of construction. PNNL performed a cost-effectiveness analysis using DOE's methodology. The cost of variable frequency drives continues to drop. Incremental cost for VSD and associated controls is $3,670 for fans powered by 5.0 horsepower motors. Energy savings for the 5.0 horsepower motor with VSD is $407 per year for a simple payback of 9.02 years. The Savings to Investment Ratio (SIR) is 1.4 in typical HVAC&R systems indicating that the present value of the savings is greater than the incremental cost. The complete cost effectiveness
analysis is attached with this proposal.

when ERV is installed.

Cost Impact: Will increase the cost of construction. Ventilation optimization is required only where an appropriate DDC system is already included in the building design. ERV is not required by this change, so the added cost is only to program the ventilation optimization into the DDC system. This is a standard protocol already required by code elsewhere, so the basic standard DDC programming is readily available and custom programming should not be required. The additional setup cost for four systems in a building with a total of 22 zones is estimated at $3,000. Additional analysis of the savings interaction between ventilation optimization and exhaust recovery ventilation (ERV) has determined that in all climates, having VAV system ventilation optimization in addition to ERV is cost effective. The annual savings for the prototype 22 zone office building was found to range from $406 to $7,039, depending on climate zone and to average $2,624 annually across all U.S. climate zones.

CE168-16	C403.4.4.7 (New)	Adds new Section C403.4.4.7 “Parallel-flow fan-powered VAV air terminal control”. This proposal addresses control of fans in fan powered parallel VAV boxes. The fan is only required during heating; however, these fans may be programmed to run continuously during occupied hours.

Cost Impact: Will not increase the cost of construction. This represents a setup of controls and does not require new equipment, so there is no anticipated cost increase and cost
effectiveness analysis is not required.

This proposal updates the values and equations in the table to reflect the new federal minimum standards for these products. The proposed modifications make table corrections and add explanatory footnotes for certain types of water
heaters.
.

Cost Impact: Will increase the cost of construction. The new federal standard significantly increased the initial cost of residential water heaters, especially for large storage water
heaters with a rated volume above 55 gallons.

CE185-16	C405.2.1, C405.2.1.1, C405.2.1.3 (New)	Modifies text of Section C405.2.1 “Occupant sensor controls”, C405.2.1.1 “Occupant sensor control function”. Adds new Section C405.2.1.3 “Occupant sensor control function in open plan office areas”. This proposal adds occupant sensor control to open plan office areas.  The code change was further modified by the Committee.  The modification coordinates the
threshold with other thresholds in the code.

Cost Impact: Will increase the cost of construction. The cost for additional lighting controls in open office areas is expected to be about $250 per 400 square foot workstation area
for simple controls, or $0.95 per square foot for advanced wireless control systems; however, there are significant savings associated with these applications. Cost-effectiveness: PNNL performed a cost-effectiveness analysis using the established DOE methodology.1 Results of the cost-effectiveness analysis showed that the average savings-to-investment ratio (SIR) is 2.2 to 1.4 in typical offices, depending on the sophistication of the system installed. A proposal is cost-effective when the SIR is greater than 1.0, indicating that the present value of savings is greater than the incremental cost. The complete cost-effectiveness analysis is available

Adds more stringent requirements on timeswitch systems for exterior lighting. Also seeks to clarifiy existing code language that is not clear.  The code change was further modified by the Committee.  The modification eliminates unnecessary text.

Cost Impact: Will increase the cost of construction. Many people interpret the current provisions of the code to require that exterior lighting be dimmable by at least 30%. While
technologically achievable, the additional wiring and controls are expensive, and in many instances the 30% reduction can be achieved by switching off lights which are not critical to safety and security. The existing code language is not clear on this point. On the other hand, by placing more stringent requirements on timeswitch systems for exterior lighting this proposal may require a more expensive control system to be used on some projects. But in reality, the big break point in time switch system pricing is from a mechanical device to a digital device, and the requirements in the 2015 IECC will already require you to use the more expensive digital device in almost all instances. Putting these two considerations together it appears that there will be a net reduction in construction costs, though this will vary from project to project.

This proposal revises the Lighting Power Density (LPD) allowances to be appropriate for currently available lighting technology.

Cost Impact: Will increase the cost of construction. Currently, LED fixtures cost more than fluorescent fixtures. So as of today, this proposal would increase the cost of construction because it will require the use of more LED fixtures. But the effect on cost of construction when IECC-2018 goes into
effect will be much less because we expect the cost of LED fixtures to continue to decline. Even though the initial cost of
construction may be higher, the use of LED fixtures will be cost effective due to the lower energy use and reduced maintenance costs of LEDs. This is already the case today according to DOE analysis. It will only improve as LED costs come down.

CE209-16	C405.4.2.2.1	Modifies text of Section C405.4.2.2.1 “Additional interior lighting power”. This proposal reduces allowance of display lighting in retail areas to encourage providing equivalent lighting levels with newer light emitting diode (LED) lamp technology. This proposal was then modified again by public comment for adopting the values recently developed by 90.1 for the following reasons:

Cost Impact: Will increase the cost of construction. Will increase the cost of construction The LED fixtures for use in display light fixtures provide more lighting output at a lower energy use. LEDs have a higher cost per lamp, but their expected life is longer, so their overall cost is lower. A survey of typical lamps in the 200 to 800 lumen output range is
shown in the following table, based on a review of online lamp prices from a national maintenance product supplier. (See table). LED prices are expected to continue to decrease, and will be lower by the time this code is adopted. Lamp costs are
normalized to 500 lumens of output and 3000 hours of operation a year or about 10 hours per day for 6 days a week. The last column in the table is the lamp cost per 500 lumens per 3000 hours, but limits the LEDs to 5 years of use at 3000 hours per year. In both the full life and conservative 5-year case, the average lamp cost for LEDs is less once lamp life is considered. The costs shown do not include additional lamp replacement labor savings or any reduction in electrical distribution costs due to lower wattage lamps.
From several points of view, the use of LED fixtures for display lighting represents a reduction in life cycle lamp costs to building owners. Cost-effectiveness: This change is cost-effective in that it provides significant savings with no anticipated life-cycle cost increase.

CE210-16	C405.4.2.2.1	Modifies text of Section C405.4.2.2.1 “Additional interior lighting power”. This proposal reduces allowance of decorative lighting n retail areas to encourage providing equivalent lighting levels with newer light emitting diode (LED) lamp technology.  The code change was further modified by the Committee.  The Modification eliminates words that were a moot point because those areas are already exempted elsewhere in the code.

Cost Impact: Will increase the cost of construction. The LED fixtures for use in many decorative light fixtures provide more lighting output at a lower energy use. LEDs have a
higher cost per lamp, but their expected life is longer, so their overall cost is lower. A survey of typical lamps in the 200 to 800 lumen output range is shown in the following table, based on a review of online lamp prices from a national maintenance product supplier. LED prices are expected to continue to decrease, and will be lower by the time this code is adopted. Lamp costs are normalized to 500 lumens of output and 3000 hours of operation a year or about 10 hours per day for 6 days a week. The last column in the table is the lamp cost per 500 lumens per 3000 hours, but limits the LEDs to 5 years of use at 3000 hours per year. In both the full life and conservative 5-year case, the average lamp cost for LEDs is less once lamp life is considered. The costs shown do not include additional lamp replacement labor savings or any reduction in electrical distribution costs due to lower wattage lamps. From several points of view, the use of LED fixtures for decorative lighting represents a reduction in life cycle lamp costs to building
owners.

CE221-16	C405.7	Modifies text of Table C405.7 “MINIMUM NOMINAL EFFICIENCY LEVELS FOR 10 CFR 431 LOW-VOLTAGE DRY-TYPE DISTRIBUTION TRANSFORMERS”. This proposal updates the minimum efficiency values required for newly purchased low-voltage dry-type transformers, and
ensures that the 2018 IECC is updated with the latest information.

Cost Impact: Will not increase the cost of construction.
As these values represent the baseline minimum requirements for all new transformers, this proposal will not increase costs for new transformers that have to meet the required increase in energy efficiency.

CE223-16	C202 (New), C405.8	Modifies text of Section C405.8 “Electrical motors (Mandatory)”. Modifies text of Table C405.8 (1) “MINIMUM NOMINAL FULL-LOAD EFFICIENCY FOR NEMA DESIGN A, NEMA GENERAL PURPOSE DESIGN B, AND IEC DESIGN N MOTORS AT 60 HZ”, C405.8 (2) “MINIMUM NOMINAL FULL-LOAD EFFICIENCY FOR NEMA DESIGN C AND IEC DESIGN H MOTORS AT 60 HZ”. Adds new definition “IEC DESIGN H MOTOR, IEC DESIGN N MOTOR, NEMA DESIGN A MOTOR, NEMA DESIGN B MOTOR, NEMA DESIGN C MOTOR”.  Deletes definition “GENERAL PURPOSE ELECTRIC MOTOR (SUBTYPE II)”, “GENERAL PURPOSE ELECTRIC MOTOR (SUBTYPE I)”. This proposal updates two motor efficiency tables to be consistent with the new federal standards. The scope of the federal standards has expanded, requiring an update to the table titles (and definitions) as well.

Cost Impact: Will increase the cost of construction. The new standards for motors will increase the cost of motors, but will save energy costs compared to the previous federal
standards. DOE estimated median payback periods on the order of 2.9 to 4.5 years, depending on the motor installed.

CE246-16	406.7.1	Modifies text of Section C406.7.1 “Load fraction”. Proposal clarifies that the minimum percentage requirements are related to a building's annual hot water requirements and not
simply to first hour rating. Removes combined heat and power system from the list of technologies that can be used to satisfy the section’s requirements. Expands the qualifying renewable energy technology from only solar energy to any on site renewable energy.

Cost Impact: Will not increase the cost of construction. With respect adding the words "of the building's annual" before "hot water requirements," this change simply clarifies the original
intent of the proposal when it was approved and would not impose any additional costs. With respect to removing CHP as a qualifying technology, such a change would not add any new requirements to the code. To the contrary, it would remove an expensive option that cannot be presumed without further information to be cost effective. With respect to expanding the solar option to include other technologies, such a change would provide builders with more choices. More choices rather than less is preferred as it puts competitive pressure on the technology providers to keep prices reasonable.

CE248-16, Part I	C407.1	Modifies text of Section C407.1 “Scope”.  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.
