California Utility Allowance Calculator (CUAC)

The California Utility Allowance Calculator (CUAC) is a California energy use model for calculating utility estimates.

E3 California offers a team of certified experts who can provide efficient and accurate utility allowance calculator results.

HUD Utility Schedule Model (HUSM)

Public Housing Authorities are required to maintain a utility allowance schedule for tenant-paid utilities, tenant supplied refrigerators and ranges, and other tenant-paid housing services. The allowance is used in determining family’s share and the housing authority subsidy. E3 California offers an expert team who can provide utility allowance results.

GreenPoint Rated

GreenPoint Rated is an approved third-party rating system for compliance with California tax incentive programs and is required by several California cities to comply with their green building ordinances.

E3 California offers a team of certified experts to get your project through the LEED certification process.

45L

45L is a federal tax credit program to offset the costs associated with building energy efficient single family or multifamily properties.
