itle 24, Part 6 (T24), California’s updated Building Energy and Efficiency Standards, went into effect on July 1, 2014 and requires a higher level of efficiency in building retrofits, as well as with new construction. The code provides a compliance path for buildings to become Zero Net Energy (ZNE) consumption compliant. ZNE means the building, over an annualized period, will generate enough energy to offset its own energy consumption.
All new construction by 2020 for residential and 2030 for non-residential will be required to be ZNE.
– The existing building path for non-residential construction will result in current building stock to be 50% retrofit to ZNE by 2030.
– Process should include T24 at the beginning of the design process.
– Two paths of compliance besides Mandatory: Performance which is based on energy budgets vs. Prescriptive which is specific to the building’s climate zone.
A Few Significant Code Revisions:
2) Occupancy Sensing Control – required in offices, conference rooms and classrooms.
3) HVAC Units are at a higher rate of efficiency, mandating economizers (bringing in fresh air) and fan control.
4) Commissioning – making sure the building’s internal systems are working as designed – required for non-residential buildings greater than 10,000 sq. ft.
5) Solar Zones – 15% of the commercial/multi-family roof must be built ready for the addition of a solar electric or solar water heating system. Residential roofs must have a minimum of 250 sq. ft. solar ready.
6) Lighting Controls – required when replacing more than 10% of the lighting or 40 ballasts. Requires multi-level control to increase granularity and use daylight harvesting and dimming.
7) Plug Load Controls – requiring automatic shut-off control in office buildings.
8) Hotels and Multi-family buildings require occupancy sensors and automated controls for interior and exterior lighting.
All of the controls and higher efficiency equipment will result in less energy being wasted and consumed by the building, ultimately leading to ZNE.
Green EconoME consults on ways your building can meet these Title 24 requirements and save energy and money. We understand that this process is costly and complicated, so we provide a clear financial analysis with costs and ROI calculations and payback periods.
