Keeping a New Building Like New
In the first 3 to 4 years of operation, “building performances typically deteriorate as much as 30%.” Block 44, located in Seattle’s South Lake Union technology hub, is managed and operated by CBRE. Completed in 2014, Block 44 is a 395,000 ft² Class A, LEED Platinum certified office building. Even though Block 44 is a new building, setpoint and sequence modifications, manual system overrides, tenant activity, deferred maintenance, and space-use changes can lead to operational drift within the building automation system (BAS) and ultimately inefficient building performance. Wanting to ensure like-new building operation was maintained at the facility, CBRE turned to ATS for solutions.
ATS facilityCARE Informatics
ATS augmented CBRE’s existing controls support agreement by adding their data informatics service, facilityCARE. The ATS facilityCARE service identifies energy and cost saving opportunities through ongoing machine-based commissioning, advanced fault detection, reporting, energy monitoring and analytics.
ATS integrated facilityCARE software into Block 44’s Alerton BAS and began holding monthly system operation and performance reviews with CBRE to discuss operational deficiencies and develop a path for improvement. By combining an extensive library of automated analytics and fault detection with facility operations expertise, ATS proactively identified system inefficiencies and solutions that would not have been detected during normal day-to-day maintenance activities.
The ATS facilityCARE service allowed CBRE to move from a traditional facility operations approach to one of continuous facility improvement, driven by data. Through the data, ATS identified thousands of mechanical and control system operational faults that would typically lead to building performance deterioration. By cataloging and prioritizing system faults for correction, cumulative system runtime was reduced by 35,000 hours in the first year. Even with rising occupancy, and the tendency for building performance to deteriorate as much as 30% in the first few years, the total energy consumption was reduced by 6% year-over-year. In addition, the facilityCARE process identified more than $10,000 in electrical system issues that were resolved through warranty, at no cost to the building ownership
