Sandia pioneers software for smart and sustainable institutions

Phys.org, September 18, 2014

Sandia National Laboratories’ Institutional Transformation (IX) model helps the federal laboratory reduce its energy consumption and could help other large institutions do the same.

The IX model allows planners to experiment with , such as adding cool roofs or replacing old heating, ventilation and air conditioning (HVAC) systems, before making expensive changes. It also models operations-oriented conservation methods, such as changing the temperatures in buildings and changing the ramp-up and -down times of HVAC systems.

“IX integrates  conservation effects across many buildings, using many conservation methods and renewable energy options, over many years. This allows planners to experiment with many different strategies across the entire institution and over time. It allows them to select the strategies that save the most energy and then demonstrate their effectiveness,” said Sandia facilities manager Jack Mizner.
