SB-12 Prescriptive Compliance Path
• No software
• Zone 1 and Zone 2 (heating degree day 5000)
• Glazing assembly area from grade to top ceiling
– Not including front door
– 17% or less, table 2.1.1.2.A, 2.1.1.2.B, or 2.1.1.2.C
– 17-22%, windows upgrading is required
– Shower water energy recovery unit
– More than 22% , go to performance path
• Easy to follow
• More restrictive

Heating equipment efficiency
• No AFUE requirement for
– Solid burn and earth energy system
– Other heating equipment
