Task 1: Simulation and Modeling

 

Task 1 Fact Sheet

The applications for simulation span the design and operational life cycle of buildings and are critical in completing the feedback loop that enables actual performance in operation to inform future designs. Simulation can be used to compare design alternatives, evaluate energy code compliance and certify post-construction energy performance through the use of rating and labeling programs. The Simulation and Modeling task focuses on practitioners that design and operate energy systems in buildings and on technical areas identified by stakeholders in India and in DOE’s Building Technologies Program Multi-Year (2011-2015) Work Plan. We aim to add significant capabilities to existing and new building design, operation, and evaluation tools in order to promote dramatic improvements in energy efficiency by:

  • Reducing barriers to energy efficiency by enabling the use of practitioner-oriented, interoperable simulation tools for integrated design, commissioning and operation
  • Developing new methods for reducing the energy consumption and managing the peak load of existing and new buildings – focusing on controls and automated diagnostics

 Project Impact:

  • Specification and development of eDOT, an early design optimization tool for predicting building energy use early in the design  process
  • Automation of performance-based code compliance (Appendix G and Indian Energy Conservation Building Code ECBC)
  • Model predictive control (MPC) of radiant slab cooling for energy savings and peak load reduction/shifting
  • Model-based fault detection and diagnosis (FDD) for commissioning and routine operation of dedicated outdoor air systems (DOAS) developed in a new Fault Detection and Diagnostics (FDD) laboratory at IIIT-H
