CBERD is conducting analyses of how buildings in India and the U.S. use energy through a Lif
ecycle Performance Assurance Framework (LPAF) that supports building system integration throughout the building’s design, construction, and operation. This departure from the conventional, fragmented approach will enable a whole-building, integrated view and simultaneously assure high performance, both in terms of energy efficiency and comfort/service levels.

In the CBERD LPAF framework, a crucial convergence occurs between the buildings’ physical systems by utilization of innovative building information technology. This creates metrics at the three stages
building lifecycle, in order to predict (design phase), commission (build phase), and measure
and control (operate phase) the building performance. This includes developing whole-building and
systems simulation tools/models that can estimate the building’s energy performance and provide
code compliance; controls and sensors for continuous measurement and tracking real-time
performance relative to the original design intent; and benchmarking to provide feedback loops to
the next generation of building design and operation.

The LPAF is organized primarily around two primary research thrusts:

1.  Building Information Technology Systems
2.  Building Physical Systems, with a cross-cutting focus on triple bottom line cost of energy efficiency technologies.

The research and development tasks under the two research thrusts are:

Building Information Technology thrust

Task 1: Simulation and Modeling

Task 2: Monitoring and Benchmarking

Task 3: Integrated Sensors and Controls

Building Physical Systems thrust

Task 4: Advanced HVAC Systems

Task 5: Building Envelopes

Task 6: Climate Responsive Design

Cross-Cutting activity

Cost Benefit Framework

The LPAF for integrated systems has the benefits of getting us closer to our performance targets and increasing the likelihood that the simulated results can be achieved in the real world: towards better design, building, and operations of high-performance buildings.
