NOW, THEREFORE, BE IT RESOLVED that, based upon the foregoing, the Planning Commission hereby recommends that the City Council adopt the Voluntary Green Building Program, as set forth in Exhibit A. ADOPTED this 13th day of June 2012. AYES: 6, Roberts, Vice Chair Hudson, Klatchko, Calerdine, Munger and Chair Donenfeld NOES: None ABSENT: 1, Conrad ABSTAIN: None ATTEST: V CITY OF PALM SPRINGS, CALIFORNIA AGUIDE TOTHE VALLEY -WIDE VOLUNTARY GREEN BUILDING PROGRAM Green For Life is an energy -saving program funded by the California Public Utilities Commission through Southern California Edison and administered by the Coachella Valley Association of Governments. Nm 101 __ ? This GUIDE was produced by the collaborative effort of Southern California Edison, Coachella Valley Association of Governments, Terra Nova Planning & Research and Interactive Design Corporation. Wj6m-greenfQd fecv ors This GUIDE to the Valley -Wide VOLUNTARY GREEN BUILDING PROGRAM introduces the issues of energy efficiency in buildings from the practical perspective of a property owner: "What should I do (to save energy/money)?" This practical introduction is not comprehensive, but rather is a "soft" opening. A knowledgeable person may choose to skip over these few pages. This GUIDE is an introduction to the VOLUNTARY GREEN BUILDING PROGRAM and the GREEN BUILDING MANUAL which is the "meat and potatoes" of the Program. You can find the GREEN BUILDING MANUAL online at www.greenforlifecv.org. 0 CHAPTER ONE, the next section, addresses the primary "things to do" with more information. CHAPTER TWO illustrates the principles that underlie the "things to do." This section is intended to help interested citizens, building owners, contractors and professionals become more fluent in the language of "green building." If one understands the principles of energy -efficient design, other actions can also be taken to complement and supplement the basic "What should I do?" actions. (CHAPTER THREE) Finally, because this Voluntary Program and the California Building Code are based upon standards and measurements, the Voluntary Program includes an extensive checklist of specific actions, and how they are counted toward a more energy efficient ` building. What follows is the INTRODUCTION to the Valley -wide VOLUNTARY GREEN BUILDING PROGRAM. 3 1c) f it � [��► �' r� �, �- � The purpose of the VOLUNTARY GREEN BUILDING PROGRAM Is to answer three questions: "What should I do to make my building more energy efficient?" "Why do those actions reduce energy usage?" "How are the effects of doing those actions measured?"

Here in the Valley, we want protection from the sun: we park our cars under carports or under trees; we want roofs over our patios; we like the shade from trees. But the sun also feels good part of the year. So controlling exposure to the sun is the trick. In the desert, cooling our buildings takes a lot more energy than heating them. So a common sense approach to energy saving is to shade the west (and south) sides of our buildings - with trees, patio covers, even "living walls."

HOW TO ACHIEVE THE SUSTAINABLE DESIGN OPTION & WHAT IT WILL ACCOMPLISH GRAPHIC DETAIL OF SUSTAINABLE DESIGN OPTION — ''1 The rest of CHAPTER TWO includes explanations and illustrations of the principles that underlie "Why does it save energy?" For example the idea of "cool roofs" is explained in terms of the solar reflectivity and emissivity of a roof. ROOF: Roofs get hot because they absorb the sun's energy. A "cool roof" is a system that reflects sunlight and doesn't absorb (reflectivity), store and "emit" a lot of heat (emissivity). The minimum values for a "cool roof" are: 0 Reflectivity > 0.70 (Black tar - 0.10; Pure white - 0.95) Emissivity > 0.75 (Aluminum foil -0.90; Black tar - 0.20) U vs R: The U factor measures the entire assembly of a window, wall, roof, etc. The R-value is the resistance to thermal transfer of a single component (glass, insulation, stucco, etc.) To get the U-factor, you add up all the R-values and divide into 1 -- sort of. 17 Ee G L See CHAPTER TWO of the GREEN BUILDING MANUAL for full pages.

Energy efficient windows resist conducting heat by double glazing and insulated frames; this is measured by the "U-value." Windows resist radiant heat transfer by coatings (low-e) on the glass; this is measured by SHGC (solar heat gain coefficient.) Here in the Valley (Climate Zone 15), the practical minimum values are: U-factor 0.35 (lower is better) SHGC 0.30 (lower is better) INSULATION: Insulation resists heat transfer by creating air pockets.

CHAPTER THREE of the Voluntary Program is the technical scorecard and point system of the energy saving building measures. The more green principles used in your building, the higher your scorecard will read in this Program. TYPE OF BUILDING SPECIFIC TOPIC See CHAPTER THREE of the GREEN BUILDING MANUAL for full pages. 21 MOM C� Like CHAPTERS ONE & TWO, CHAPTER THREE is organized by building type (homes, apartments, and businesses) and progresses from issues outside the building (site conditions, building orientation, drainage, etc.), to the building envelope (roof, windows, etc), to the structural system (framing systems), to equipment selection and finally passive strategies and health considerations. Each item is also cross referenced to other rating systems (Cal Green, LEED, Green Point) to direct a design professional toward further investigation. 22 www.gmgnb-r&cv.org See CHAPTER THREE of the GREEN BUILDING MANUAL for full [)ages.

All the design and equipment choices are listed and assigned a point value, and a "score card" is created for your building. When the points are totaled you will know whether the building meets or exceeds the minimum goal of the Voluntary Green Building Program: to exceed Title 24 by 15%. Some of the items listed are mandatory (M) and some are already part of Title 24 energy calculations. These are highlighted in green (naturally) so one could simply select those items in green and they will directly improve Title 24 calculations. You may be able to reach the +15% simply by upping the values of these "green" items. Items not highlighted in green do not directly relate to Title 24, but are valuable for energy efficient buildings. These items are assigned "points" and when the adjacent "check box" is checked, a running total is started. 4 www.gregnforlifecv,org See CHAPTER THREE of the GREEN BUILDING MANUAL for full pages. te' HVAC equipment Carefully considerthe energy efficiency CG A4.407, es selected In this Code that will Wuence the actual heat load on the LEED FA t3.1, 1'dloning system.

As part of this Program, some Cities have committed to making it easier for those voluntarily participating in the Program to process their plans through the planning and building departments. The requirements are different for each city. Please check the permitting process of your individual city. Inspections by the City will continue to be required for the mandatory T24 requirements of the California Energy Code. These inspections are provided by the City's Staff (Building Department Inspector). 35 N 101 C 36 2*41 _1!&V1 IFP) W1, M I IOU i T� - The VOLUNTARY PROGRAM is self -reporting (except for the Title-24 credits.) It is based upon an honor system: you say you are going to do something to improve the energy efficiency of your building, and we believe that you will. However, there is great value to have third party verification of the actual installation of various measures. Now, why do we say we will trust you, but not your contractor? Simply because the complexities and idiosyncrasies of every construction project present challenges to contractors. Sometimes they miss something, overlook something or simply make a mistake. It is in your interest to confirm that what the plans and specifications state, and what you pay for, are actually well -executed. Therefore both the California Energy Code and the VOLUNTARY PROGRAM place high value on third party verification of four major elements: insulation, duct leakage, whole house leakage, and HVAC equipment. The first three require careful attention to detail and connections. Insulation and ducting is often installed improperly. HVAC requires proper sizing of the equipement prior to purchase. By inspecting insulation and duct work before walls are closed up (so errors can be corrected), the overall performance of the building is greatly enhanced. Professionals such as Home Energy Rating System (HERS) inspectors, are available to provide these services. Every process of manufacturing and fabrication requires quality control; you can think of third -party verification as construction quality control. wwwaLeenfadifacv.ag -. t Where else to look for information... Energy conservation is on everyone's mind, but it isn't always easy to find your way around all the programs and websites. Below are links to some of these organizations -- ones we think are especially relevant to our Desert Climate. By no means is the list comprehensive, but it will get you started looking for more information - or the same information presented differently. Southern California Edison http://www.sce.com The California Energy Commission http,//www.energy.ca.gov/title24/ California State Energy Code http://www.bsc.ca.gov/Home/CALGreen.aspx United States Green Building Council http://www.usgbc.org Build It Green http://www. bu i ld itgreen.org/gree n p of nt-rated/ California Energy Upgrade https.//energyupgradeca.org/ 3 N CQ�4UES ARCHITECTS AND DESIGNERS: The Voluntary Green Building Program and this GUIDE are learning tools. As practioners, we know how overwhelming and intimidating Building Codes are - for us and our clients. So we start with practical questions: "What should I do?" (to save money and energy). We give some simple practical steps, and then we illustrate the principles that underlie energy efficiency. By starting simple and explaining terms and ideas, we hope everyone who uses this Program will have discussions about what options are available and appropriate for their project. Our goal is to bring "green" into the entire process of imagining, designing and building. CONTRACTORS: The Voluntary Green Building Program and this Guide are intended to help everyone who uses this Program understand the principles of energy efficient building. We have organized the Program and this GUIDE around the practical question "What should I do? (to save energy and money)". The Program is set up so you and your client can discuss the options available and appropriate for their project. Using the Program to help explain the principles behind energy efficient building, you can be an advisor as well as a builder. Finally, the California Energy Code and the construction industry will continue to evolve toward the goal of "net zero" buildings. Becoming an advocate and expert now places you as a leader in your industry. 38 www.greenforlifecv.org CITY STAFF: We all recognize that the California Energy Code continues to evolve. The COACHELLA VALLEY GREEN BUILDING PROGRAM (CVGBP) is voluntary. We see it as a "soft opening" to energy efficient measures that will soon be mandatory. The Program is also a learning tool to help explain both the "what and why" of energy efficiency building. We start by asking "What should I do? (to save energy and money)". We then illustrate and explain specific measures (cool roof) so that the owner, the designer, the contractor can all discuss the options that are available and appropriate. The Program is intended to be a learning tool to help demystify the California Energy Code and other energy efficiency measures. Because the Program is voluntary, it is more an invitation than a mandate for the entire project design team to consider energy efficiency from the initial concept through the entire construction process. 39 101 E3swrtoERN CALIFORNIA EDISON An WISON l.VTERNA MIX it.- C mp8. www.greenfQriifecv.org, w
