Green Roofs: Policy + Simulation

Green Roofs: Policy + Simulation

On November 7, 2017, the citizens of Denver passed the Denver Green Roof Initiative that mandates buildings over 25,000 square feet to dedicate a percentage of it's roof to green, vegetative space. For this SimClub event, we have invited Jill Jennings Golich from the City of Denver to discuss the policy details of this initiative, as well as Professor Paulo Tabares to discuss the technical issues of simulating green roofs in building energy models. This includes the heat and transfer mechanisms modeled, the impacts to building energy consumption, assumptions, simulation gaps, validation variables and climate conditions, as well as recommended future work.

Jill Jennings Golich has a bachelor’s degree from the University of Denver, and a Master’s in Public Administration from the University of Washington. Jill started her career with CRL Associates in their Development Services division, and then moved to Design Workshop where she led the entitlement effort for the Denargo Market project off Brighton Boulevard. 

From 2007-2014, Jill worked at the Auraria Higher Education Center eventually serving as the Director of Campus Planning.  Since April 2014, Jill has served as one of the Deputy Directors for the City of Denver’s Community Planning and Development Department.  In this position, Jill led the successful adoption of the 2015 International Codes, serves as point person for CPD related to regulation of the marijuana industry, and is leading implementation of the voter passed green roof initiative. 

Dr. Paulo Cesar Tabares-Velasco is an Assistant Professor in the Department of Mechanical Engineering at Colorado School of Mines. His research interests are in building energy simulation, thermal storage, smart materials, heat and mass transfer applied to buildings and building integration with smart grid. Before joining CSM, Dr. Tabares-Velasco was a Research Engineer at the National Renewable Energy Laboratory (NREL) where he was a developer of NREL’s building simulation/optimization tool BEopt and led NREL technical research on phase change materials in collaboration. Prior to NREL, Paulo was a Research Assistant at the Pennsylvania State University (PSU) where he developed a new apparatus to test the thermal performance of vegetated roofs under control conditions. He also developed a new heat and mass transfer model for vegetated roof systems. Paulo’s work on vegetated roofs has been recognized with the 2009 Crosby Field Award, 2009 Willis H. Carrier Award and 2009 Best Poster Award by the American Society of Heating, Refrigerating, and Air Conditioning Engineers (ASHRAE), the 2011 Green Roof Research Award of Excellence by Green Roof for Healthy Cities (GRHC) and a NSF video production.
