Sample text

In its initial stage, the program addresses energy consumption and cost in three specific ways: • Fault detection and diagnosis to enable timely and targeted interventions in cases of faulty or under-performing building equipment. • Alarm management to prioritize the many notifications generated by existing building systems and point engineers to the most impactful issues. • Energy management through systematic tracking and optimization of building energy consumption and performance over time, while changing the behavior of building occupants with visual dashboards and benchmarks.

Rather than installing building analytics and AFDD in buildings, companies are collecting data, analyzing it at a central location, and reporting their findings to building managers. , AFDD, that provide conclusions about faults in buildings automatically. Regardless of how the faults, opportunities and recommendations are developed at these service centers, the distinctive feature of this delivery model is that results are provided as a service, which will meet the needs of certain building owners, who choose to use outside experts rather than devoting their resources to developing their own ex- perts in a field outside their core business.

The saw tooth line in Figure 2-3 illustrates how building efficiency declines between retro-commissioning efforts. Through this prior approach, Microsoft typically achieved energy savings of about 4 million kWh each year, cutting costs by about US$250,000. Now, the introduction of automated fault detection and diagnosis provides an entirely new tool for Microsoft’s building engineers, enabling them to identify and prioritize faults as they occur. The smart building solution provides engineers with a table similar to the simplified example in Figure 2-4, where equipment faults are prioritized and the cost of wasted energy is automatically estimated.
