Dr. Jin Wen and student Liam Hendricken recently ran a workshop for the Philadelphia Housing Authority (PHA) for training on energy modeling and energy modeling software, EnergyPlus. Over a three day period, Drexel provided theoretical background on energy modeling followed by a practical workshop using EnergyPlus so that PHA staff could develop an understanding of how to use the software to run energy conservation measure (ECM) retrofit studies for their sites. This workshop was used by PHA staff in an on-going, internal effort to make employees aware of sustainable practice and efforts (an effort headed by PHA’s Barbara Moore and Herman Arce).
