5 PROJECT HISTORY

6 PROJECT HISTORY History of Dining Needs for Dining Circumstances of key departments Call for creative thinking by the President Sustainability, collaboration and a teaching building A student-centered space A University Center that engages the community

7 LEADERSHIP: A CLEAR VISION Gonzaga seeks to create an imaginative facility capable of inspiring current and prospective students envisions that the new facility will be a unique architectural and functional asset that engages students, faculty, staff, the general community, and the world by creating a fusion of new and traditional experiences of learning, socializing, and engagement.

8 OPENING THE WORLD TO EACH OTHER The new context of globalization requires us to act as a universal body with a universal mission realizing at the same time the radical diversity of our situations. It is a worldwide community and simultaneously as a network of local communities that we seek to serve others across the world. -SUPERIOR GENERAL A. NICOLAS, S.J.

9 BUILDING A SENSE OF PLACE! the concept of dwelling assigns importance to the forms of consciousness with which individuals perceive and apprehend geographical space. More precisely, dwelling is said to consist in the multiple "lived relationships" that people maintain with places, for it is solely by virtue of these relationships that space acquires meaning. KEITH BASSO, WISDOM SITS IN PLACES: NOTES ON A WESTERN APACHE LANDSCAPE

10 FROM IDEA TO DESIGN Supporting the whole student to become reflective, ethical leaders of tomorrow

11 COLLABORATIVE VISIONING

12 PLACE OF COMMUNITY & CONVERSATION

13 MAKING CONNECTIONS Personal Global

14 BUILDING BRIDGES Places to Meet Places to Work

15 LIGHT EVERYWHERE

16 Healthy Materials Sustainable Food Cycle 100 % Daylight / Views Green Roof LED Lighting Geothermal Wells SUSTAINABLE FOCUS

17 LEED GOLD CERTIFIED LEED GOLD 69 points! 40% less water used indoors compared to the baseline building code. 546,000 gallons of water saved per year, the equivalent of 31,778 showers.! 63% reduction in annual carbon dioxide emissions compared to similar existing buildings nationwide = 2,548 tons of CO2 saved each year.! 92.5% of the construction waste = 3,871.6 tons diverted from the landfill.! Indoor air quality enhanced by use of interior materials and furniture with low chemical emissions.!

22 PART 2: DATA DRIVEN OPERATIONS & MAINTENANCE BRICE KOSNIK, CEO & Co-Founder, BuildPulse Inc., John J Hemmingson Center TOMSON SPINK, Facilities Maintenance Manager, Gonzaga University, spinkt@gonzaga.edu

23 SUSTAINABLE HVAC OPERATIONS! High Rate of Occupant Comfort Avoid Hot and Cold Calls Avoid Stuffy Conditions Appropriate Occupancy Schedules and Set Backs! Minimal Equipment Maintenance and Repair Low number of repair and operational Issues Continuous Retro Commissioning Continuous Fault Detection! Low Energy and Carbon Consumption Low demand and consumption Year over year reduction in Energy Use Intensity (EUI)

24 TAKING MEASURE.HOW GONZAGA DOES IT Automated Logic (United Technologies) Operates the system Manages comfort Controls energy flow to HVAC systems BuildPulse Provides fault detection Continuous retro-commissioning BuildingOS (Lucid) Measures energy consumption Creates public interaction and reports results

25 BUILDING COMMISSIONING STARTS WITH FOUNDATION Setpoints Scheduling Sequences TOP 12 ISSUES 1. HVAC system operates continuously during unoccupied period 2. Lighting system illuminating space during unoccupied period 3. HVAC system improperly balanced 4. Improper refrigerant charge 5. Economizer dampers operating incorrectly 6. Insufficient evaporator airflow TOP 12 ISSUES 7. Improper controls setup 8. Control component failure or degradation 9. Software programming errors 10. Improper controls hardware installation 11. Air-cooled condenser fouling 12. Valve leakage Reference: PNNL - A Guide to Building Commissioning

26 CLIENT EXAMPLE How long does it take to? Test Every Sensor, Valve, Damper, & Relay 90 buildings 2 Dedicated Techs

27 AUTOMATION THAT DRIVES EFFICIENCY! Analytics automates the manual processes and audits that we don t have time for.! 4 Man Years or 5 Minutes! Manual Inspection still requires verification

28 SETPOINTS TYPICAL SETPOINT MANAGEMENT

29 SETPOINTS Band Aid Fixes Raising or lowering the setpoint so the unit is always heating or cooling is not addressing the actual issue. Consider resetting all setpoints during unoccupied hours. Apply Minimums and Maximums Deadbands should not just be +/- one or two degrees on a general setpoint. Do not allow heating setpoints above 70 or 72, and do not allow cooling setpoints lower than 74 or 76. Use Minimum Percentage for Parent Mode Instead of determining mode based on a single minimum zone requirement, use an average of all or require that at least 20% of the served equipment is calling for the highest energy mode. For example cooling in winter.

30 THAT DRIVES EFFICIENCY tes the s and t have rs s SCHEDULES QUICKLY AUDIT EQUIPMENT RUNTIME n tion

31 SCHEDULES IDENTIFY ANOMALIES buildpulse

32 SCHEDULES IDENTIFY ANOMALIES

33 SCHEDULES Confirm with Equipment Just because the schedule is set correctly does not meant the equipment is following it, verify schedule adherence with runtime data from the equipment. Maximum schedule resolution When ever possible use zone level scheduling, avoid a single schedule for the entire building. Holiday and Exception scheduling can be nested to apply global changes from one location. Optimal Start / Stop Effective optimal start maintains a memory and trains itself to heat or cool based on the individual zones rate of change in heating or cooling mode.
