Presentation 1: 
Speaker: Kylie Zhao, PE, Affiliated Engineers Inc., 

Water is currently an undervalued commodity and is often overlooked in the building modeling process. By integrating water modeling into the design process of commercial spaces, we can evaluate the effects of various conservation strategies and provide a more complete picture of consumed resources. In this presentation, we will review benchmarking and whole building modeling strategies, while we compare the effects of various conservation strategies on overall water consumption. We will also identify common water modeling challenges and provide resources for improved model accuracy. 

Presentation 2: 
Speaker: Megan Gunther, PE, LEED AP, WELL AP, Affiliated Engineers, Inc. 

As energy and water conservation targets continue to increase, so does the complexity of building systems to meet these goals. New technologies are rapidly being developed, however, simulation tools are not being developed at the same speed. Because of this, tools are incapable of accurately modeling the physics and controls of these complex systems. 
This presentation highlights the limitations of modeling indirect-direct evaporative cooling using IES-VE and compares results with a custom-developed tool. The custom spreadsheet tool was developed for preliminary analysis, predicting cooling coil load reduction after two-stage evaporative cooling. A case study of a northern California commercial office building will be use to explain how evaporative cooling was modeled in an annual simulation. A comparison of results will be made.

It is widely recognized that building energy use results in significant greenhouse gas emissions and high performance design presents a significant opportunity to reduce energy use and carbon dioxide emissions. 
As we move towards an all-electric future with zero or low carbon buildings through decarbonization of the electric supply grid, it becomes imperative to
