If the design score for your initial estimated energy use no longer meets the Designed to Earn ENERGY STAR (DEES) threshold, you must determine if design strategies and systems can be improved to meet an ENERGY STAR score of 75 or above for certification.
Complete the following steps in Portfolio Manager or Target Finder:
- Select a target score of 75 of higher,
- Use the updated annual energy use or EUI target for your energy goal.
Look for opportunities during design and construction to modify design strategies and improve energy efficiency to boost your score. Comparing your modeled energy to the design target should be performed throughout the process to determine if changes along the way will help to reach your goal. Examine the different “end uses” in your energy model to evaluate whether additional strategies for heating, cooling, fans, lighting, domestic hot water, or plug loads should be targeted.
Finally, commissioning can help to ensure that systems and components are calibrated to occupants needs and functioning as designed to reduce energy waste and improve efficiency. Once the building is occupied, continue monitoring energy use and make necessary adjustments to control sequences, setpoints, and schedules to achieve optimal performance and efficiency.
