For Performance Rating Method (App. G) Revised Calculation for “Index of Merit”

• Performance rating method: a calculation procedure thatgenerates an index of merit for the performance of buildingdesigns that substantially exceeds the energy efficiency levelsrequired by this standard or when using the performance ratingmethod as an alternative path for minimum standard compliancein accordance with Section 4.2.1.1

• 2019 – for new buildings and alterations/additions• When using Appendix G, the Performance Cost Index (PCI)

shall be less than or equal to the Performance Cost IndexTarget (PCIt) when calculated in accordance with the following:

% Savings = 100 x [(PCIt – PCI)/ PCIt]


23

Calculation to Comply Using Appendix G• PCIt = [BBUEC + (BPF X BBREC)]- PNA / BBP

Where • PCIt = Performance Cost Index Target• PCI = Performance Cost Index= [Proposed Building

Performance]/[Baseline Building Performance]• BBUEC = Baseline Building Unregulated Energy Cost• BPF = Building Performance Factor from Table 4.2.1.1*• BBREC = Baseline Building Regulated Energy Cost• PNA = Proposed renewable energy contribution not

allowed for compliance (New 2019)• BBP = Baseline Building Performance

*Table 4.2.1.1 – For building types not listed use “all others.”For multi-use buildings use area-weighted average.


24

PNA – New for 2019• We do not want Renewables to result in worse walls or

mechanical systems• Therefore the savings from renewables to show

compliance is limited to 5%• PBP = Proposed Building Performance including the

reduced, annual purchased energy cost associatedwith all on-site renewable energy generation systems

• PBPnre = Proposed Building Performance without anycredit for reduced annual energy costs from on-siterenewable energy generation systems.

• Renewable contribution = PBPnre – PBP• Renewable Fraction = ( - PBP)/BBP if<=5 PNA=0 -

if>5• PNA = Renewable Contribution – (0.5 x BBP)


25

Table 4.2.1.1:2019 Building Performance Factors (BPFs)


26

Example – Show Compliance

Inputs– An office building in Chicago(CZ-5A)– Area = 50,000 ft2 - Office Building– Proposed Building Performance has been calculated at =

$32,000/year– BBP = $49,000/year BBP = Baseline Building Performance– BBREC = $34,000/year BBREC = Baseline Building Regulated Energy

Cost– BBUEC = $15,000/year Baseline Building Unregulated Energy Cost

Lookup– 2019: From Table 4.2.1.1, for Office in Climate Zone 5A, the BPF = 0.51– 2016: From Table 4.2.1.1, for Office in Climate Zone 5A, the BPF = 0.60

Calculations (next slide)


27

Example – Show ComplianceCalculations 1. PCI = Performance Cost Index= [Proposed Building

Performance]/[Baseline Building Performance]PCI = $32,000/$49,000 = 0.65

2. PCIt = [BBUEC + (BPF X BBREC)] / BBPWhere PCIt = Performance Cost Index Target

PCIt = [$15,000 + (0.51 X $34,000)]/$49,000 = 0.66

3. Since PCI at 0.65 < PCIt at 0.66, the building complies4. Savings = 100 x [(PCIt – PCI)/ PCIt]

= 100 x [(0.66 - 0.65)/ 0.66] = 1.5 % Same Building in 2016 saved 9.7%

If we added renewables we could only count a maximum of 5% for compliance.

Federal Projects

Federal projects must use 30% less energy than the current addition of 90.1. The calculation used is not the calculation from 90.1. The calculation, shown above, is based on consumption and does not include unregulated loads. It has been recently based on 90.1-2013, but in November, 2019, it is based on 90.1-2016.

§ 9.1 General: Scope of Requirements

• Requirements apply to: (§9.1.1)

– Interior spaces of buildings– Exterior building features– Exterior building grounds lighting provided through the building’s

electrical service

• Requirements apply to:– New construction– Alterations to existing buildings (§9.1.2)

– the lighting requirements are triggered only when 20% or more ofthe connected load in a space or area are replaced (§9.1.2)


92

Lighting Power Trade-Offs

• Separate requirements exist for:– Exterior– Interior

• Each system must comply separately with theirrespective requirements

• Trade-offs between the two are not allowed

• Trade-offs are only permitted:– Interior lighting – among spaces– Exterior lighting – among some (safety excluded)

All lighting shall be automatically controlled to turn off when the building is either unoccupied or scheduled to be unoccupied.

Exception: Lighting load not exceeding 0.02 W/ft2 (0.2 W/m2) multiplied by the gross lighted area of the building shall be permitted to operate at all times.

Each space shall have a manual control device that allows the occupant to reduce lighting power by a minimum of 50% and to turn the lighting off.

Office spaces less than or equal to 250 ft2 (23.2 m2), classrooms, conference rooms, meeting rooms, training rooms, storage rooms, and break rooms

These spaces shall also be controlled by manual-on occupant sensors.

Office spaces greater than 250 ft2 (23.2 m2) and restrooms

These spaces shall also be controlled by occupant sensors.

Stairwells and corridors in office buildings and parking garages

These spaces shall also be controlled by occupant sensors that reduce the lighting power by a minimum of 50% when no activity is detected for not longer than 20 minutes and be controlled to turn off when the building is either unoccupied or scheduled to be unoccupied.

Parking garages 0.13 W/ft2 (1.4 W/m2)

Building type = office

Lighting power density =

1.0 W/ft² (in 2004)0.64 W/ft² (in 2019)

Gross lighted area = 100 ft x 90 ft = 9,000 ft²
