Understanding California's 2016 Energy Code: Title 24 / Section 6 Introduction Do Dryvit's Outsulation EIFS brands meet the CA Energy Code for construction in the nation’s most populous state? Yes, they do. Meeting the building code is really about compliance to rigorous standards and determining whether EIFS' provides compliance to this complicated part of the CA Building Code can be daunting. This paper focuses on the exterior wall section of the CA Energy Code; and finally how Outsulation makes for compliant construction. Here are some important considerations as we 'dive' into this subject: 1. Exterior Insulation & Finish Systems (EIFS) are defined in the CA Nonresidential Building Code (Vol. 1, Section 1408, pg. 719) as a 'wall covering', 2. the code does not separate wall coverings as insulated or non‐insulated, 3. the energy code sets a minimum U‐Value for a building's wall type (mass wall, wood or metal framed, metal building etc.), a. while CI is not mandated in a performance driven compliance, as lower and lower U‐Values become commonplace, some kind of CI is practically unavoidable, b. the wall's combined component U‐Value must meet the prescriptive U‐Value as stated in the code's standards, 4. there are six volumes of energy related appendices, standards that serve to 'amplify & support' Title 24/Section 6 and the three volumes comprising the CA Residential & Nonresidential Building Code. Background In 1974 California became the first state in the United States to implement minimum energy standards as part of its core governing values. The California Energy Commission (CEC) was estab‐
lished by the Legislature under the Warren‐Alquist Act (1974). The 1974 law was essentially the same as a 1973 bill that was vetoed a year earlier by then Governor Ronald Reagan. In the months ensuing after the veto the US was plunged into the throes of gasoline and natural gas shortages as a byproduct of the Arab Oil Embargo. While the original intent of the legislation was to help wind down Californian's hefty use of fossil fuels, the oil embargo put an urgency on fuel reduction that the governor was unable to argue against. Reagan capitulated after civic leaders and a state house revolt—lead by Democrats and Republicans, forced him to reconsider the measure, and it became law in late 1974. 1 The CEC sets minimum energy efficiency standards covering autos, appliances, lighting, and of course buildings through the CA Building Code. The CEC writes the efficiency standards for the Building Standards Commission (BSC) which ultimately writes, manages and produces the CA Building Code for each county and city to adopt. There are two codes, CA Non Residential Code and CA Residential Code. The Department of Housing and Community Development is the legal authority under which BSC operates Recognizing that buildings consume around 50‐
55% of all energy produced, the CEC has focused on making sure California's Building Code fosters significant energy savings. While the law predates the development of our electricity dependent digital existence the code's prescience has helped Californian's use less energy per capita than any state in the US. This is despite an explosion in energy consuming devices at home and work. Understanding California's 2016 Energy Code: Title 24 / Section 6 The California Energy Commission is the state's primary energy policy and planning agency. These seven core responsibilities guide the Energy Commission: 1. Forecasting future energy needs; 2. Promoting energy efficiency and conservation by setting the state's appliance and building energy efficiency standards; 3. Supporting energy research that advances energy science and technology through research, development and demonstration projects; 4. Developing renewable energy resources; 5. Advancing alternative and renewable transportation fuels and technologies; 6. Certifying thermal power plants 50 megawatts and larger; 7. Planning for and directing state response to energy emergencies. More Recently In 2008, The CEC was challenged by then California Governor Arnold Schwarzenegger to achieve the lofty goal of Zero Net Energy* by 2020 for the CA Residential Building code and the same by 2030 for the CA Nonresidential‐‐
commercial, code. These parameters and goals are often referred to as ‘Cal Green’ and are set out in Section 11 of Title 24. It’s a lofty goal, and to reach it, the CEC and BSC have embraced the goals outlined by the IECC (International Energy Conservation Code) and have instituted mandatory higher minimum standards for lighting than those in the IECC. Schwarzenegger and others believed that California as a huge and densely populated place, would allow it to lead in energy efficiency by bringing market impact on the US economy and beyond. As a result of this impact many manufacturers agree to build to the CEC’s energy standards knowing that they are welcome in the California marketplace, and in many cases that means those items meet the standards for markets in Europe, Canada and elsewhere in the US. In composing the Title 24 standards, the CEC follows the International Energy Conservation Code, and in some instances adds additional energy conservation measures in the form of 'elective' standards. The CEC also allows individual jurisdictions to apply stricter standards on a petition basis. As an example, the cities of San Francisco, Pasadena and Palo Alto applied for and were given permission by BSC and CEC in 2014 to require the elective sections of the lighting and water usage code to apply as mandatory (in those jurisdictions) to new construction as well as alterations. Title 24 / Section 6 To be specific, the energy standards for the CA Building Code are contained in a section of CEC code called ‘Title 24 / Section 6’. Title 24 covers a wide ranging area, but it’s Section 6 that we are concerned about, because it’s Section 6 where the wall's thermal performance standard is defined. What do The Standards Look Like? The Standards are divided into three basic parts. First, there is a basic set of mandatory requirements that apply to all buildings. Second, there is a set of performance standards – the energy budgets – that vary by climate zone and building type; the Standards are tailored to local climate conditions. * ZNE refers to a goal to insure that a newly built building by 2020 and 2030 will use no more energy than it can also generate (e.g. photovoltaic, wind or ground well harvesting) or thru conservation. 2 Understanding California's 2016 Energy Code: Title 24 / Section 6 The third set constitutes an alternative to the performance standards, which is a set of prescriptive packages that are basically a recipe or a checklist compliance approach1. 1. Mandatory Requirements 2. Performance Standards 3. Prescriptive Standards (also 'elective' standards that exceed the current code) A project may utilize performance so long as the energy use can be shown to be equal or less than it would be under prescriptive. These standards and requirements can be found beginning on page 43, in the 2016 Building Efficiency Standards (a full set of these Standards is attached). The efficiency standards apply to residential and nonresidential buildings and to both new construction and alterations to existing construction. The Climate Zones In order to better tailor the application of the Title 24 / Section 6 efficiency standards and in recognition of the nuances of climate in such a large area, the state of California has been divided into 16 climate zones.

How to Get Confirmation to the CA Energy Code The designer may elect to use either a performance or a prescriptive path to gain confirmation. However, beginning with the 2013 CA Code confirmation that a design is compliant is demonstrated by using a CEC approved on‐line software2 that issues a watermarked 'certificate of compliance'. The designer then submits the certificate to the local building department. The CA Residential code favors using the prescriptive path, as the designer simply chooses from a menu of assemblies already verified by CEC Standards. CA Nonresidential code (commercial buildings) typically favors a performance path to confirmation. Confirmation, documentation and calculations by CEC acceptable software is still required. What Really Happens Using Performance Path Under performance path and transparent to the user, the software is constructing a prescriptive version of the same building and is constantly comparing the choices being entered in performance with those allowed prescriptively for the building. The software allows the designer to 'shift values' around as the design is entered and the software sifts and sorts the design to verify conformance. 1 Excerpted from the "Abstract", page 4, Building Energy Efficiency Standards for Residential & Nonresidential Buildings, For the 2016 Building Efficiency Standards. Published by The State of CA. 2

While U‐Value and U‐Factor terms are often used interchangeably, applied correctly, U‐Factor is an expression of the wall's totality (accounting for insulation values, thermal bridging, fenestrations, etc.) including at what rate warmth transfers through the assembly. IMPORTANT: WEIGHTED U‐VALUE An average resulting from the multipli‐
cation of each component by a factor re‐
flecting its overall importance in the wall. Whenever two or more types of a building feature, material, or construction assembly occur in a building, a weighted average of the different types must be calculated. Weighted averaging is simply a mathe‐
matical technique for combining different amounts of various components into a single number. Some would say that the U‐Factor is most accurate way to calculate the wall’s thermal performance. Image Courtesy Pacific Homes 4 Understanding California's 2016 Energy Code: Title 24 / Section 6 Old to Now: Changes to Wall Design in 2016 CA Energy Code (effective Jan 2017) Mandatory and prescriptive changes for the opaque portion of nonresidential wall construction focuses on increasing the wall's thermal efficiency across the board. Some of that improvement will come from "upping" the amount of insulation in areas where CI is currently required and some will come from requiring CI in nearly every Climate Zone. For The 2016 Energy Code, changes to Title 24 / Section 6 standards can be located in California Energy Standards beginning on page 180 (to 184), Table 140.3B to D. To find how the 2016 code will differ from the 2013 version, it's necessary to review all the tables of standards (there are about 6) and compare 2013's to 2016's. It's a tedious job. But there is one dramatic change afoot, which going forward favors the use of an Outsulation: Light Gauge Metal Framed Exterior Walls That dramatic change in U‐Factor is represented in 2016's Table 140.3C (below). The required U‐Factor for metal framed exterior walls (the major substrate for projects in CA using Outsulation systems) will increase. On average and as shown in my "example" comparison, a 34% upward bound improvement in that wall will be required. (2013/Table 140.3C at end paper.) This same increase will affect other types of projects, like MOB's and educational projects. 2016 Prescriptive Table of Standards, CA Energy Code, Table 140.3‐C EXAMPLE ‐ Compare 2013 code to 2016 code for a building built near me in Santa Rosa CA: Light Gauge Metal Framed Wall 16" o/c Framing 5/8" Gyp Board Interior / Exterior / No Cladding Determined Maximum U Factor Zone 3 & Effective R‐Value for the wall (no cladding) 5 Zone 3 Table 140.3‐C 2013 Zone 3 Table 140.3‐C 2016 U‐Value of 0.105 / U‐Value of 0.069 / Effective R‐Value Effective R‐Value of 9.52 of 14.50 Net U‐Value Difference 2016 from 2103 Net % Increase In Required U‐
Value 2016 from 2013 0.036 +34% Understanding California's 2016 Energy Code: Title 24 / Section 6 How Does an Outsulation Clad Wall Conform? Dryvit’s Outsulation systems are ‘continuous insulation’. CI can be the difference between a wall meeting the code or not. Dryvit's Outsulation brand is 'continuous insulation'. Because it is adhesively fastened and lacks thermal bridging it is the only perfect CI with no conductive fasteners or components. The conductive properties of metal studs are offset by the super insulating qualities of Outsulation which then allow for offsets within the calculations allowing for larger windows and reduced cavity insulation. By using Outsulation systems (CI), batt insulation can be reduced, or even eliminated, and the use of deeper studs can be avoided. The changes to require CI in most exterior wall construction in California have been slower than other states, because the state already had rigid requirements for cavity wall insulation and heavy mass wall to provide thermal protection. California has played catch up through the last code cycle, by updating other parts of the energy code (roof construction, lighting, gas appliances etc.) before focusing on wall construction. In the 2016 code that catch up has come full circle, and the code will force the use of CI in a way that more closely aligns with the International Energy Conservation Code. REFERENCES: 
