As the Passive House standard continues to make waves across New York City and the U.S., an entirely new design process has evolved to respond to the challenges of higher insulation levels, balanced mechanical ventilation, and perhaps the most difficult hurdle – an air tightness level that most would think is impossible. For the recently certified Cornell Tech building on Roosevelt Island, the tallest Passive House in the world, a several year-long coordinated effort was required to achieve such a feat. So what is the requirement, how is it measured, and what are the strategies and considerations required to achieve it?
The number of multifamily residential projects targeting Passive House certification has been rising steadily over the past several years, bringing along many exciting challenges. This has been especially prevalent in New York City, where increasingly stringent energy standards and a desire for innovation have made designing to Passive House standards an attractive goal. As the number of these projects passing through our office continues to grow, we have discovered some important overlaps with one of our other consulting services – Accessibility Compliance.
In the United States, multifamily new construction projects consisting of four or more dwelling units are subject to the Fair Housing Act, as well as state, city, and local accessibility laws and codes. For the purposes of this blog we will focus on projects in NYC, although the majority of newly constructed residential projects across the country will be subject to some variation of the criteria discussed below, for both Passive House and Accessibility standards. With this in mind, we have chosen a couple of common problem areas that require particularly close attention. Read more
Many green building programs put a heavy emphasis on not only the sustainability of a building once it is built, but increasingly so on the sourcing and management of building materials in an environmentally responsible way. Sustainable Supply Chain (SSC), sometimes referred to as “cradle-to-cradle,” is the standard term to reference this process. But, what does it mean?
What is a Sustainable Supply Chain?
SSC embodies a cyclical approach to manufacturing that considers both the recovery and reuse of materials. This supply chain’s reverse logistics strives to continually sustain itself by returning materials to the land in either a safe molecular form or by continually reusing those materials for future products. Fully developed SSC’s consider sustainability for every contributor at every step – from design to manufacture, transportation, and storage to eventual end-of-life with a goal of re-use, recycling, or low impact disposal. This forward-thinking perspective serves to reduce waste, promote ethical and socially beneficial manufacturing practices, minimize or eliminate adverse health impacts, and enable compliance with increasingly stringent regulations.
