HELPFUL INFO ABOUT TITLE 24

2019 Title 24 Part 6 Building Energy Efficiency Code (Residential) have major changes to Prescriptive Envelope Requirements. The most significant improvements to the residential Title 24 Standards include improvements for attics, walls, water heating, and lighting:

Envelope, Water Heating, HVAC And Lighting

Energy Design Rating (EDR)

 

is a way to express the energy consumption of a building. It is a rating score index where 0 (zero) represents a building that has zero energy consumption and 100 represents the energy consumption of the building built to the specifications of the 2006 International Energy Conservation Code (IECC) home. The EDR is calculated using California Energy Commission approved compliance software.

Time Dependent Valuation (TDV) Energy

 

is the time varying energy use by the building to provide space conditioning and water heating and for specified buildings lighting. TDV energy accounts for the energy used at the building site and consumed in producing and in delivering energy to a site, including, but not limited to, power generation, transmission and distribution losses.

NEW CONSTRUCTION

projects using the performance approach will be required to comply with both the:

  • Maximum EDR score (includes Heating/Cooling/DHW)
  • Maximum TDV score (includes above and lighting/appliances/receptacle uses/PV)

ADDITIONS & ALTERATIONS

projects using the performance approach will only be requried to comply with the TDV budget

Photovoltaic System:

PV System is now required to comply with Title 24 requirement for all single family and multifamily buildings.

  • DC Rating = (CFAxA)/1000+(NDwell*B)
  • CFA = Conditioned floor area
  • NDwell = Number of dwelling units
  • A = Adjustment factor from Table 150.1-C
  • B = Dwelling adjustment factor from Table 150.1-C

For Example, 2,000 SF home (Climate zone – 9) will require 2.6 kW system.

Title 24 Water Heaters:

Tankless Water Heaters are now standard. Tank type water heaters are considered to be sub-standard solution unless it is a high-efficienty Heat Pump water heater. Gas tank-type water heaters may require HERS verifications, compact piping design, and increase in PV system capacity.

Title 24 Walls:
U-factor reduced to 0.048

  • 2×6 @ 16″ OC framing – R21 cavity insulation AND R-5 continuous (in most Climate Zones).
  • 2×4 @ 16″ OC framing – R15 cavity insulation AND R-8 continuous (in most Climate Zones).
  • there are several options that allow extensions of existing wood framed walls to retain the same dimensions

Title 24 Attics:

  • Option-A: HVAC unit and ducts located in attic:
    • Install attic radiant barrier (CZ 2,3,5,6,7)
    • Install R-38 insulation at ceiling (R-30 in CZ-3,5,6,7)
    • Install R-19 below roof deck insulation at rafters (CZ 4, 8-16)
  • Option-B: HVAC and ducts must be located in conditioned space
    • Install radiant barrier (CZ 2-14, and 16)
    • Install R-38 insulation at ceiling (R-30 in CZ 2-10)

Quality Insulation Installation (QII) and HERS verification
is now required on most residential buildings under Prescriptive compliance.

  • This applies to New Construction as well as Additions > 700 sq.ft.
  • Exception: Climate Zone 7 not required for multi-family (Coastal San Diego)

New Title 24 compliant window:

  • Maximum U-Factor = 0.30
  • Maximum SHGC = 0.23

New Title 24 compliant door:

  • Maximum U-Factor = 0.20 (R-5 insulated door)
  • Doors with 25% or more glass now treated as fenestration (windows).

California’s Building Energy Efficiency Standards, commonly known as Title 24, are updated on an approximately three-year cycle. The 2022 Title 24 Standards will continue to improve upon the 2019 Title 24 standards for new construction of, and additions and alterations to, residential and nonresidential buildings.

The effective date of the current 2019 Title 24 Standard is January 1, 2020.

ENERGY EFFICIENCY STANDARDS

 

WHY CALIFORNIA NEEDS TITLE 24 ENERGY STANDARDS?

Energy efficiency reduces energy costs for owners, increases reliability and availability of electricity for the State, improves building occupant comfort, and reduces environmental impact.

Energy Savings

Reducing energy use is a benefit to all. Building owners save money, Californians have a more secure and healthy economy, the environment is less negatively impacted, electrical grid can operate in a more stable state.

Electricity Reliability And Demand

We learned during the 2000/2001 California energy crisis, and the East Coast blackout in the summer of 2003, that our electric distribution network is fragile and system overloads caused by excessive demand from buildings can create unstable conditions. Resulting blackouts can disrupt business and cost the economy billions of dollars. Since the California electricity crisis, the Energy Commission has placed more emphasis on demand reduction.

Comfort

Comfort is an important benefit of energy efficient buildings. Energy efficient buildings include high performance windows to reduce solar gains and heat loss, and properly designed HVAC systems, which provide improved air circulation.

Economics

For the building owner, energy efficiency helps create a more profitable operation. From a broader perspective, the less California depends on depletable resources such as natural gas, coal, and oil, the stronger and more stable the economy will remain in the face of energy cost increases.

Environment

The use of depletable energy has led to oil spills, acid rain, smog, and other forms of environmental pollution that threaten the natural beauty of our planet. California is not immune to these problems, but the Appliance Efficiency Regulations, the Energy Standards, and utility programs that promote efficiency and conservation help to maintain environmental quality.

The Title 24 Energy Standards are expected to have a significant impact on reducing greenhouse gas and other air emissions.

The Energy Commission’s Title 24 energy efficiency standards have saved Californians billions in reduced electricity bills since 1977. The Title 24 Part 6 Building Energy Efficiency Standards were first adopted in 1976 and have been updated periodically since then as directed by statute.

The Title 24 part 6 standards are divided into three basic sets:

  1. a basic set of mandatory requirements;
  2. a set of performance standards (the energy budgets which vary by climate zone);
  3. an alternative to the performance standards, which is a set of prescriptive packages that are basically a recipe or a checklist compliance approach.
