1385 N. McDowell presented several HVAC design challenges to drive adequate energy and service savings. Original design incorporated parallel air distribution and relatively new equipment – Both counter-productive to degradation and energy savings. Engineering staff at Basin-Street properties were looking to achieve maximum savings with an emphasis on energy reduction in a 52k sq. ft. building already operating with high-efficiency standards.
Integrate with the existing building systems to generate 30-40% HVAC energy savings and reduce service calls without upgrading or replacing equipment.
BUILDING AUDIT & STRATEGY
Autonomous Calibration & Repairs
Our virtual engineer Hank exceeded our expectations when managing every HVAC unit in the building. Not only did Hank manage equipment at minimal operating cost, he was able to find and autonomously repair 6-different, repetitive HVAC software issues. The charts show Hank learning the flow setpoint for VAV 1-6 in the building and automatically adjusting the setpoint to reverse sub-cooling in the space.
Scheduling & Tenant Billing
We’ve built Optimal Building Scheduling algorithms into Hank’s AI, letting him learn how each zone group achieves comfortable temperatures in relation to key predictor variables like adjacent group temperatures and outside air – Reducing starting times by almost 68% within ASHRAE comfort tolerances. Hank was also able to capture off-hours zone usage and report key analytics including total cost and start/end times.
Our virtual engineer Hank correlated over 300 points and 32,000 historical archives into his AI to determine lowest cost of operation for all 56-different HVAC units. Every minute, Hank forecasted thousands of different operating conditions for each unit and autonomously selected the most economical operating conditions – All leading to comprehensive energy reduction across the entire building without sacrificing tenant comfort.
The 1385 N. McDowell building presented several design and management challenges we had to overcome to achieve success. Parallel air handlers serve each air manifold for each floor simultaneously; Ultimately eliminating degradation disparities between units but requiring advanced optimization strategies to achieve savings.
Basin-Street also employs their own engineering staff to manage building HVAC systems and respond to service calls. Our service proved to be cash-flow positive solely on energy savings, although we still reduced HVAC-related service calls by 60% and unit degradation by 32% – Extending average equipment life nearly 6-years!
