1. 1 Experimenting with Efficiency: Greening the Grant T EAM GREEN DINOSAURS Sandeep Dey, Wan Yin Cheung, Yung Nguyen Michelle Tang, Sze Wun Wong

2. MODERN LABS INEFFICIENT ❖ Research labs consume 3-5 times more energy than offices Offices Research Labs ❖ Significant energy savings possible ■Replace equipment – 44% ■Optimize HVAC - 55% ■Occupancy sensing - 30% ❖ Lab environment does not promote sustainability ■Affiliated personnel uninformed ■Lack of enforcement policies 2

3. CHALLENGES Awareness ❖ Monitor energy only at building level ❖ Researchers have no feedback on energy consumption Efficiency ❖ Outdated equipment are power hungry, increase HVAC load ❖ HVAC systems not optimized for lab usage Accountability ❖ Indirect cost rate policies do not encourage energy efficiency ❖ Lack of accountability for energy expenditures Implementation ❖ Lack of personnel to facilitate sustainability ❖ Limited funds for energy efficiency measures 3

5. AREAS TO IMPROVE 5

6. MONITORING ❖ Breakdown energy consumption ■Lab level electricity consumption using subcircuit meters ■Appliance level monitoring for energy intensive equipments ■Leverage existing sensors for estimating HVAC energy  Analyze energy usage and find savings opportunity 6

7. FEEDBACK & EDUCATION ❖ Energy feedback to occupants ■Interactive display, monthly reports ■5-15% energy savings  Reminders ■Turn off lights/equipment ■Solid waste disposal ■Regular maintenance ❖ Education ■Yearly workshops ■Online tutorials of sustainability measures ■Include lab members, staff, janitors, facility managers 7

8. AREAS TO IMPROVE 8

9. EQUIPMENT 20-45% of lab energy ❖ Facilitate green equipment procurement ■ Link to resources - Labs21, Green Procurement ■Centralize purchase of commodity items ■Tool Lending Program - encourage sharing ■Encourage task lighting, LED lights  O&M of heavy equipment ■Regular cleaning of freezers ■Turn off fume hoods, incubators ■Automate using timers, occupancy sensors  HVAC optimization ■Proper equipment sizing ■Move equipment to machine room 9

10. HVAC 45-60% of lab energy ❖ Upgrade ■CV to VAV system (RoI 6-10 yrs) ■Dedicated cooling system (RoI 0.25 yrs) ❖ Optimize ■Ventilation Requirements ■Occupancy based control ❖ Maintain ■Automated fault detection system ■Expedite repair of energy expensive faults ❖ Leverage financing options available ■PACE program ■SDG&E retrocommissioning program 10

11. COMPUTING ❖ Increasing dependence on computers ■Tablets, laptops ■Wake-on-LAN, Somniloquy ❖ Energy efficient options ■No maintenance, zero energy consumption ■Cloud services optimized for high energy efficiency ❖ Encourage cloud-based services such as AWS ■Centralized management of computing services ■Use of Energy Star servers (30% savings) ■Separate hot and cold aisles in data centers ❖ University data center for custom needs 11

12. NEW CONSTRUCTION/RETROFITS ❖ Unique opportunity to be sustainable by design ■High energy savings ■Long lasting effect ❖ Design of permanent fixtures ■Floors - durable repairable ■Ceiling - light colored, low VOC ■Windows - blinds, tinting ■Countertop, furniture ❖ HVAC ■Design based on simulation models ■Low pressure drop design, optimize ventilation ■Adequate sensors for continuous commissioning 12

13. AREAS TO IMPROVE 13

14. INEFFICIENCY DOESN’T PAY ❖ Make energy expenses as direct cost ■Labs will encourage sustainability measures ■Penalizes inefficient labs ❖ Federal grant policies ■Mandate purchase of sustainable equipments ■Construction/retrofit grants set design standards ❖ Publicize sustainability in University ■Sustainability awards across research labs ■Advertise successful sustainability projects 14

15. AREAS TO IMPROVE 15

16. RESEARCH FACILITY MANAGER ❖ Identify inefficient research labs & help with sustainability measures ❖ Educate researchers/staff on energy efficiency ❖ Develop a web portal with sustainability resources and guidelines ❖ Keep up with state-of-the-art measures by attending research conferences ❖ Conduct yearly inspection of research labs 16

17. PHASED APPROACH Pick a Test Building Identify Sources of Lab Inefficiency Implement low- cost sustainability strategies Expand to Larger Scale 17
