An in-depth presentation addressing the pending implementation of the 2013 California Energy Code, Part 6, Title 24, effective July 1, 2014 and the design and construction implications for roofs, walls, skylights and windows.


Nelson Peña, California Energy Commission
Nelson Peña, Associate Mechanical Engineer, California Energy Commission,  Energy Efficiency and Renewable Division and is one of the Principal Technical  Editors of the California Energy Efficiency Regulations and Compliance Manual.  Nelson is a Board of Director for the National Fenestration Rating Council. Nelson  has over 15 years of experience training Architects, Plan Checkers, Field  Inspectors, and Building Officials for California State Agencies and Building Jurisdictions throughout California, and teaches part time at Diablo Valley  College.

PRESENTATION SUMMARY: Nelson Pena will present an overview of the  changes to the 2013 California Energy Code, Part 6, Title 24, Effective July 1,  2014. He will cover a brief energy code history, energy savings, introduction to envelope regulation and will go over residential and non residential envelope and reference appendices.

Learning Objectives:

1. Attendees will be able to identify at least three prescriptive performance requirements for high performance windows under the new California Energy Code.

2. Attendees will be able to identify three major changes in mandatory requirements for residential lighting.

3. Attendees will be able to explain maximum air leakage rates for the Bay Area climate.

4. Attendees will be able to state three changes in commissioning requirements.

Mark Brink, WASCO Skylights
Mark Brink, Midwest Sales Manager, Wasco Skylights. CSI Member and Sales  Manager for over 25 years. Mark has worked with America’s leading skylight  manufacturers on projects from simple unit skylights to skylights for the Mall of  America, one of the largest skylight projects in the United States. Mark’s  experience and education have given him a keen understanding of skylight  design considerations including climate responsiveness, building code  requirements,  and daylighting and energy savings benefits of skylights.
PRESENTATION SUMMARY: Mark Brink will focus on skylights. Skylight  options (aerogel, acrylic, polycarbonate, and glass) that meet the 2013 California  Energy Code will be presented.

Michelle Murray, Sage Electrochromics
Michelle Murray, Business Development Representative, Sage Electrochromics,  the leader in electrochromic glazing. Michelle has promoted the benefits of  SageGlass electrochromic glazing technology to Architects and Engineers, LEED
and Energy Consultants, Owners, Contractors, USGBC, CSI and other  professional construction organizations through local and national presentations  and product trade show exhibits for daylighting products. An Independent Sales  Representative and Manufacturer Product Representative Michelle has spent the  last decade in the construction industry specializing in daylighting technology.
PRESENTATION SUMMARY: Michelle Murray will talk about vertical window requirements. Glass options that meet the 2013 California Energy Code will be  presented.

Philip Dregger, Technical Roof Services
Philip Dregger, Professional Engineer, Registered Roof Consultant, Fellow of the  Roof Consultants Institute, and President of Technical Roof Services in Concord,  California. Philip has spent more than 25 years investigating, designing, and  providing expert witness testimony regarding virtually all types of roof and waterproofing systems. Phil has special expertise in hygrothermal (moisture and heat) analysis and has authored technical articles and papers on the subject  including “Cool Roof Cause Condensation – Fact or Fiction”.


Starting July 1, 2014, prescriptive minimum requirements for aged solar reflectance for low-sloped roofs in CA will increase from 0.55 to 0.63.  Will the higher values cause condensation?  (Answer – It depends.)  Did the old values condensation? (Answer – Sometimes.)  This presentation will explain how old non-reflective built up roofs helped control condensation (moisture accumulation) by getting hot every time the sun came out.  And, how switching to a highly reflective “cool” roof can sometimes inadvertently create a condensation problem by disrupting the balance between seasonal wetting and drying.  Left unchecked, excessive condensation (moisture accumulation) can lead to reduced energy efficiency, mold growth and wood decay in roofs.  Three strategies to avoid condensation in roofs will be presented.

Learning Objectives:

  1. New and revised CA Energy Code requirements related to roofs (e.g., reflectance, insulation, air barriers)
  2. How old “hot” roofs helped keep us out of trouble and why “cool” roofs sometime cause problems.
  3. The overwhelming difference air intrusion makes.
  4. Why strip-foam-adhering roofs over new concrete over metal decks, is a condensation challenge.
