Speaker Bios Alejandra Menchaca Alejandra is a Vice President for Thornton Tomasetti’s Sustainability practice, and has been based in the Boston office since 2017. She combines expertise in mechanical engineering and building science to give clients a clear understanding of the impact design strategies and innovative solutions have on a project’s carbon emissions. Alejandra leverages research and simulations to provide project teams with sustainable design knowledge and energy expertise. She is experienced in the design of both passive buildings and energy-intensive structures such as laboratories and healthcare facilities. Her expertise also includes thermal comfort, energy modeling, daylighting and computational fluid dynamics. Alejandra holds a PhD from MIT in Mechanical Engineering, and has taught courses on natural ventilation and energy in buildings both at MIT and the Harvard GSD. David Madigan Dave has more than 30 years of professional experience in new and renovated buildings in a variety of sectors that includes colleges & universities. A recognized expert on sustainable design, Dave has worked on numerous projects with high performance design objectives. Of particular note is Dave’s experience in the design and planning of high efficiency, sustainable laboratory facilities and the design and implementation of campus energy conservation measures. He has served as Vice President and Principal of van Zelm since 1993. Dave holds a Master of Science in Building Energy Engineering from the University of Colorado and a B.S.C.E. degree from Villanova University. Dave is a LEEDTM-accredited professional who has been utilizing sustainable principles in his own projects since the early 1980s. A frequent lecturer on the practice of energy conservation and sustainable design, Dave has addressed industry groups such as ERAPPA, NNECERAPPA, APPA, NESEA, Lab Wize, and I2SL. Elaine Hoffman As a Certified Passive House Consultant, Elaine is a champion for high-performance envelope design and a leader in the use of analytical modelling as a design tool. As Co-Chair of Goody Clancy’s 2030 Committee she has expanded firm-wide conversations about WELL and Fitwell for creating healthy facilities while stewarding the project energy goals and data collection for the AIA 2030. In addition to managing this process internally, Elaine also participated in the AIA 2030 Commitment–DDx Development Task Group to improve the data-exchange interface. Her background in environmental studies expands these conversations beyond energy and water consumption into the life-cycle impacts of our buildings on the natural environment and human health. In this case study, Elaine led the thermal detail and life cycle assessment modeling that accompanied Thornton Tomasetti’s thermal comfort and energy modeling, demonstrating how to use performance analysis during concept design to create a project scope that enables campus-wide carbon reduction plans.
