Slate Upper School: Building with Purpose-Driven Innovation

February 13, 2024

Patriquin Architects discusses the new Slate Upper School in North Haven, a thoughtful evolution of Slate School’s award-winning, nature-based lower school campus. Now in construction and scheduled to open in the Fall of 2024, the Upper School’s evidence-based design strategies include optimized building orientation and envelope detailing to manage heat gains, thermal bridging, and moisture, and an over-arching emphasis on healthy materials that contribute to the well-being of building occupants and our planet.


  • How to specify and detail a high-performance building envelope that uses principles of Passive House to address thermal bridging, air infiltration, vapor and moisture management, and solar heat gain to contribute to a healthy learning environment.
  • How to leverage databases such as the International Living Future Institute’s Declare to aid in the research, evaluation and specification of materials and assemblies that can be healthier for occupants and for the global environment.
  • How the right mix of envelope materials, systems equipment selections, and user input can provide exceptional IAQ, thermal, acoustical and lighting comfort while also lowering operational carbon emissions and energy use intensity.
  • How design firms evolve their practice over time and adopt emergent technologies that push us forward towards a carbon-neutral and equitable built environment. Leverage tools for energy modeling, daylighting simulations, and embodied carbon calculators and how they can influence the design and construction process.
