Summary District energy (DE) with combined heat and power (CHP) offers many potential benefits to college and university campuses, including energy cost savings and reduced CO2 emissions. At the same time, a potential DE-CHP system may look promising initially but be thwarted due to several...
2B.2_Johnstone, Kolwey_FINAL.pdf
Summary This session will explore a case example using an excel-based energy and economic modelling tool to provide a quick, first order evaluation of district energy and combined heat and power alternatives for a proposed development project. The model provides valuable information to enable...
