Building renovation and new construction can be very expensive. With the improvement in technology in HVAC equipment and building materials the payback period of investing in energy efficient measurements is the smart choice in Energy Engineering. Modeling buildings in energy simulation programs such as Trace 700 allows Energy Engineers to compare Energy Efficiency Measures (EEM). With the information gathered from this data, cost-effective means can be evaluated. EEMs are used to evaluate variables in building and can help associate the trade-offs between cost versus savings. I will be writing a few posts on EEM topics and what I learn as I go!
