HERS Certification Requirements
 Buildings that are 3 stories or less can have a
HERS rater that is certified for Residential only
 When buildings are 4 habitable stories or more
the HERS rater must also be certified for
Non-Res
What HMG Will Provide to HERS Rater
 Site superintendent’s name and phone
number
 Energy Measure Summary sheet so you
know what Energy Measures are required
per Title 24

Energy Measures Summary
CMFNH HERS Verification Requirements
 Every individual plan
 A total of 15% of building (sampling OK)
 Title 24 Energy Efficiency Measures Verified
Title 24 Energy Measures Requiring Verification






Windows and glass doors: verify NFRC sticker
Insulation pre-sheet rock: verify R-value of wall and attic insulation
HVAC equipment efficiencies: verify model numbers and efficiency
Water heating efficiencies: verify model numbers and efficiency
Pumps and miscellaneous efficiencies
Storage tanks: verify that there is insulation and the water storage
capacity
 Garage ceiling insulation: podium floor
Note: these verification protocols are in addition to any HERS
measures called out on your Title 24 documentation for compliance
purposes.
HERS Verification Procedure
 Schedule site visits with site superintendent
 Always check in at project site office and talk to site
manager before you do any verifications
 Verify insulation and glazing first
 Verify mechanical (HVAC) model numbers & efficiencies
 Verify boilers, pumps and storage tank insulation &
capacity
 Look at garage insulation if any

Labeling Pictures
 Get a set of floor plans from builder to write down picture
numbers and information gathered
 Name each picture so you can identify where picture was
taken from your set of floor plans
 Example: Plan1A_Unit 200_R-19 Wall
 Enter all information from each site visit into a project HERS
folder
Example Plan Mark-Ups
Example Plan Mark-Ups
When Installed Measures Differ from Expected
 If installed measures differ from Energy Measure Summary
 Mark up sheet with the differences and e-mail to HMG
 HMG will work with the Energy Consultant to revise the Title 24 with
as built information
 HMG will load into registry the as built CF-1R to CMFNH multi-plan
before HERS rater completes project
HMG Verification
 To ensure QC of inspection process
 Spot check of some buildings, sometimes with the
rater
 In addition to the QC activities of the HERS
Provider
 QC is primarily the HERS Providers’ responsibility
CalCERTS
 We are now going to talk about converting EnergyPro
models from high-rise residential to multi-family low-rise
 Show everyone what reports are needed while loading a
project, and how to fill out those reports
