Every month NAPHN Chapter, Passive House Rocky Mountains‘ has an online meeting with presentation. This past month’s presenter was NAPHN’s CPHT Trainer, Ben Leer, talking about passive house windows.

Passive House windows are one of the most critical aspects of the building’s overall performance.

Daylighting elements are striking and desirable building features that historically come with costly challenges such as leaks, energy loss, thermal discomfort, and condensation issues. Passive House level glazing addresses these issues by optimizing performance and design. Learn how to design, spec and install aesthetically-focused window systems designed to be thermal-bridge-free, and suitable for high performance envelope needs.

Fenestration of all kinds requires special attention, but is especially important in Passive House buildings, where they are fulfilling more occupant needs. Potential for thermal bridging, overheating, cold air convective currents and air or water leaks can dampen or destroy the gains of free daylight and visual comfort. The designer’s challenge is to meet both the aesthetic and performance demands of the building envelope.

This seminar covers methodologies for selecting PH daylighting solutions, presents case studies and lays out design considerations that apply to commercial or residential, flat or pitched roof, curtain wall systems, historic preservation retrofits and more.

Ben Leer has had a diverse career focused on sustainability and the urban environment. He graduated with a MS in Sustainable Architecture from the City University of New York and has since consulted on numerous projects, ranging from ecological infrastructure to Passive House design. Ben specializes in high performance daylighting systems and has given numerous talks and workshops on the topic. He is currently an NAPHN Trainer for the NAPHN’s Certified Passive House Tradesperson Course and is an instructor at Rensselaer Polytechnic Institute where he teaches building science.

He has a passion for creating environmentally friendly buildings, and is deeply committed to the Passive House movement.
