Who Are We? Host: Gina Rodda Gina Rodda, our host for the Decoding Talk series, is a Certified Energy Analyst (CEA), and LEED Accredited Professional (AP). Gabel Associates, LLC gina@gabelenergy.com She is involved in providing residential and nonresidential energy calculations for a variety of building types throughout California; an instructor of full day trainings; and host of various webinars specific to Title 24 (Part 6) Building Energy Efficiency Standards. Gina has been in the energy modeling field since 1991, through the course of eight California building energy code cycles. 6 Who Are We? Co-Host: Martyn Dodd Martyn Dodd, the founder and principal of EnergySoft in Novato, CA, is an industry expert in performancebased building analysis. He has written software programs used in California for Title 24 energy code compliance since 1985, including EnergyPro, COMPLY 24, and the California Energy Commission's Perform software. He is also one of the original authors of the 1992 Nonresidential Alternative Calculation Method Manual, which defines the rules for code compliance software and has become the model for national and international code compliance software procedures. 7 Our Goal Today Review the changes to Title 24 Part 6 with the 2016 code cycle: What are the major changes to this code cycle. How might this code affect our work, and how to prepare. Where can you get more information on this code cycle. 8 Who Are You? We would like to know about you. 9 Why? Why? Intent Behind the Code History of 2016 Code Cycle 2020 – Net Zero “New” Residential Homes 2030 – Net Zero “New” Nonresidential buildings 1978: Title 24, Part 6, California State Building Energy Efficiency Standards established; updates every 3 years 2003: California Energy Action Plan adopted; efficiency 1st choice in meeting future energy needs 2006: AB32, Global Warming Solutions Act, adopted to reduce greenhouse gas emissions 2008: “Big Bold Strategies” adopted – California Energy Efficiency Strategic Plan (CEESP) What? When?

This function learns the response of the system in order to calculate a start and stop time for the system so that the building is comfortable when the occupied period begins. Space conditioning systems with DDC to the zone level shall have optimum start/stop controls. 3 140.4(e)5 Dx Systems with Economizers Direct expansion (DX) systems with economizers that are: >65,000 BTUH AND Control the capacity of cooling based on space temperature Must have minimum 2 stage cooling capacity This was phased in during the 2013 code cycle, but did you know that? 3 140.4(n) System Shut-off Directly conditioned space that have a thermostatic control and OPERABLE openings to the outside (i.e. windows/non self-closing doors/skylights): When openings are left open for more than 5 minutes then Interlocked controls will disable or reset temperature setpoint to: Cooling = 90°F Heating = 55°F In our opinion… N/A to Alterations 3 120.6(f) Elevators Lighting <0.6 watts per sq. ft.
