Green & Sustainable Technologies

FIU is researching ways to improve technologies to use less electrical energy and natural resources in production and in operations while reducing waste and pollution. FIU’s ARC is developing Green Buildings by improving technologies for heating and cooling buildings, a major source of energy usage in buildings. Improvements in heating, cooling and ventilation (HVAC) is one area of research.  Another area is sustainable remediation which seeks to lower the Green House Gas footprint of operations while also reducing electrical energy use and other resources.

    • Human Occupancy based sensor system development for use in green buildings
    • Multi-objective optimization algorithms for system level integration and control in HVAC systems

HVAC Technology

Increased emphasis on energy efficient solutions leads to the development of better and optimal ways of using energy. The Heating Ventilation and Air Conditioning (HVAC) system is one of the major power/energy consuming units in buildings in the United States and worldwide. Depending on the type of facility, a chiller plant can consume electricity ranging from 10% to 50% of the total energy consumption. Hence, even a small amount of savings in energy would result in large savings in cost. Also, most of the chiller plants are not optimized.

Research Scientists at FIU-ARC are developing technologies to maximize energy savings from chiller plants by generating optimal peak performance characteristics in real-time. In addition, technologies resulting from human occupancy models and response surface based models for integration with the HVAC optimization technology are also being investigated.

Sustainable remediation

FIU has worked with the U.S. Dept. of Energy’s Office of Environmental Management in developing a primer for green and sustainable remediation.  In addition, FIU collaborated with the Savannah River National Laboratory on applying the principles of green and sustainable remediation to the groundwater remediation system at Savannah River site’s A & M Areas.  See the fact sheet below for more information on this research effort.
