For example, according equipment and building practices with our market to ENERGY STAR®, installing a highly efficient solutions package for office buildings less than variable refrigerant flow, or VRF, heating 70,000 square feet. Whether you’re planning system in a 40,000-square-foot office to build a new office or kicking off a major building can save up to $0.34 per square foot renovation, it provides a simple way to identify every year in energy costs, translating into an the best energy solutions for your office space. additional NOI of $13,496. At a cap rate* of eight percent, this results in a potential asset * NOI divided by the sales price or value of a property expressed as a percentage.

This package offers an all-in-one, step-by-step process for designing and selecting energy-efficient systems and equipment that are cost-effective and qualify for cash incentives. To help you drive for the deepest savings possible and maximize your incentive benefit, we have grouped the equipment and practices to align with four efficiency tiers. There are base requirements that must be met to qualify for incentives for each tier. You may then select additional electives to earn even higher incentives. The table below presents the base incentive amount for each tier, as well as the incentive levels when combined with electives. Incentives are calculated on a per-square-foot basis and will depend on the equipment selected and the number of elective options you install. BASE INCENTIVE BASE + 2 ELECTIVES BASE + 4 ELECTIVES VERY BEST n/a n/a $2.00/sq ft BEST $0.80/sq ft $0.90/sq ft $1.00/sq ft BETTER $0.35/sq ft $0.45/sq ft $0.55/sq ft GOOD $0.25/sq ft $0.35/sq ft $0.45/sq ft Use this workbook throughout the course of your project to set efficiency targets, select equipment, estimate incentives and facilitate communications and decision making. Your Energy Trust New Buildings outreach manager will work with you to provide input and guidance on how to maximize the energy efficiency of your building and your incentives. STEP 1 Review “Part 1: Lighting,” and select your lighting power density, or LPD,target. STEP 2 Review “Part 2: HVAC,” and select your heating, ventilation & air conditioning, or HVAC, system. STEP 3 Review “Part 3: Electives,” and select any additional equipment or systems you plan to install. Project Name Square Footage The following pages present the options for lighting, HVAC and additional elective equipment and design practices eligible for incentives. Please indicate the equipment you plan to install by completing the tables below. HOW TO USE THIS WORKBOOK 2 PART 1: LIGHTING Efficiency requirements All projects must achieve a minimum lighting power density, or LPD, of 0.78 watts per square foot. This represents a 15 percent reduction in LPD beyond what is required in the whole-building lighting power allowance for office spaces in 2010 Oregon Energy Efficiency Special Code, or OEESC. Refer to Table 505.5.2(a) in the OEESC for further detail. If you use space-by-space lighting power allowances then you must demonstrate an overall LPD reduction of 15 percent. Refer to Table 505.5.2(b) in the OEESC for further detail. Elective option Projects pursuing higher-efficiency targets can elect to achieve an LPD of 0.6825 watts per square foot using whole-building lighting power allowances, or 25 percent beyond code using the space-by-space allowances. See Part 3: Electives for further information. Required documentation Please submit the following documentation to Energy Trust along with your incentive application: F Lighting layouts and schedules F ComCheck documentation F Invoices Project information Please fill in the table below to indicate the LPD target you have selected. LIGHTING Total Allowed Watts Total Proposed Watts Square Footage of Office Space Percentage Better than Code (from ComCheck) (from ComCheck) PART 1: LIGHTING Total Estimated Incentive $ 3 PART 2: HVAC Selecting your HVAC system Selecting an HVAC system and properly sizing the equipment is fundamental to ensuring optimal building performance. Each of our HVAC options correspond to the incentive tiers presented on page 2. The most common HVAC system types for office buildings are detailed below. Once you have reviewed the options and requirements, select your system and complete the corresponding project information tables. All “good” and “better” HVAC options require economizers on units greater ECONOMIZERS than 5 tons. Installing economizers on all HVAC units, regardless of size, will automatically qualify your project for the “better” incentive tier. An economizer regulates and optimizes the amount of outdoor air brought into a building for Economizer requirements* cooling and ventilation. This • Economizers for packaged rooftop units must be factory installed. cooling is often referred to as "free cooling" because there is • The damper motor must be fully modulating. no need for mechanical systems to condition your building— • The damper drive mechanism must consist of a direct modulating actuator with gear-driven saving energy and money on interconnections and a permanently lubricated bushing or bearing on the outside utility bills. Economizers also and return dampers. improve indoor air quality by reducing carbon dioxide levels. • The economizer must include a proportional damper control. Economizers are required by • The economizer must be locked out when in heating mode. code (503.3.1 and 503.4.1 ) on units 5 tons and greater in size. • There must be a dedicated thermostat stage for the economizer. • The economizer control type must be differential dry-bulb, fixed dry-bulb, differential enthalpy or dew point/dry-bulb temperature control. • The economizer must include a changeover control with a setpoint/ dry-bulb limit of 65-75 degrees Fahrenheit, or °F. • The economizer must provide relief air with a barometric damper in the return air duct upstream of the return air damper, a motorized exhaust air damper or an exhaust fan with backdraft dampers. Elective option • If selecting a “good” HVAC system, you may receive an elective credit by installing an economizer on a three- or four-ton air conditioning unit. * Contact Energy Trust for any exceptions.

A DOAS is required for "very best" incentives. If the system also • Chilled water must be supplied by an air- or water-cooled chiller exceeding code part-load and contains an energy recovery peak efficiencies by a minimum of 10 percent at standard ARI test conditions.
