Within the past two years the building industry has shifted to a zero carbon standard, with large buildings in cities like Boston being required to demonstrate net-zero operations to obtain building permits. Residential projects have migrated to passive standards like PHIUS and PHI and large commercial projects are largely adopting fossil-fuel free heating systems. This presentation will review current trends in high-performance design and introduce students to critical engineering concepts they are likely to encounter in professional practice.


Colin Schless leads Thornton Tomasetti’s East Region energy modeling and building analytics group within their Sustainability Practice. Most recently he collaborated with BR+A in the authorship of Boston’s city-wide Net-Zero zoning standards. Prior to being located in Boston, Colin Schless led TT’s Western Region energy modeling and building physics group. Thornton Tomasetti is a 1,500-plus person multi-disciplinary engineering firm with 54 offices worldwide.  Colin’s background is in building science and he manages the company’s passive house and R&D efforts related to parametric design and analysis. His project experience ranges from a 500,000 gross square foot museum in Riyadh Saudi Arabia to the first large-scale cold-climate multifamily passive house located in Brewer, Maine.
