Energy-Effective Design


Drexel University is part of the Department of Energy's Energy Efficiency in Buildings HUB (EEB-HUB). This effort seeks to transform the commercial building retrofit market by overcoming barriers to the adoption of energy efficient technologies. Drexel University is actively participating in EEB-HUB research and educational projects aimed at greatly improving the building energy efficiency in the U.S. More specifically, the Drexel team participates in the following projects:

Whole Building Diagnostic and Decision Support Systems for Energy Efficient Operation and Cost Effective Services

Dr. Jin Wen, Principal Investigator

In this project, the Drexel team develops and demonstrates an effective automated fault detection and diagnosis toolkit for an air handling unit. The Drexel lead team is developing a library of diagnostics decision support tools that can enable cost effective diagnostics solutions for existing buildings. Whole building diagnostic and decision support tools should robustly maintain building energy performance at an optimal level following commissioning of retrofitted buildings. The prototype includes existing algorithms developed by the Drexel team that combines Principle Component Analysis technique, Wavelet Transform technique, and Pattern Matching technique.

Policy and Market Macro Modeling for the GPIC Region

Dr. Patrick Gurian and Dr. Jin Wen, Co-Principal Investigators

In this project, the Drexel team is developing a warehouse of commercial and multifamily residential building energy simulation models in support of the development of the EEB-HUB regional building energy efficiency and technology adoption model. These models are then evaluated to identify the sets of energy conservations measures that most economically meet different targets for energy conservation. The Drexel team is also developing a “Virtual Decision Maker” algorithm to simulate which retrofit technologies will be selected from the available options, based on multiple attributes, including financial returns, occupant impacts, etc. The algorithm enables computer simulation models to forecast the evolution of the building stock under alternative policy scenarios.

Dynamic Ventilation Strategies that Improve Indoor Air Quality (IAQ) and Reduce Building Energy Use

Dr. Michael Waring, Principal Investigator

In this project, the Drexel team demonstrates and develops new ventilation strategies that reduce energy use while improving IAQ, starting in office buildings, using a combination of tests in real buildings and extensive modeling over the different U.S. climate zones.
