NEW YORK CITY HOUSING PRESERVATION & DEVELOPMENT REQUEST FOR PROPOSAL

SustaiNYC : Achieving Community, Economic and Environmental Sustainability through Passive House Design


The New York City Department of Housing Preservation and Development (HPD) invited developers in 2016 to submit proposals for a new Passive House construction project in the East Harlem section of Manhattan. Paul A. Castrucci Architect was a part of a team The Community Builders, LOTT CDC, EDI International, and Urban Quotient. In 2017 the team's proposal was selected as one of the finalists.

Paul A. Castrucci Architect Passive House features and design. Key features include energy recovery ventilators, passive house quality control, passive house insulation + air sealing, triple pane windows, energy efficient VRF heat pump heating/cooling and massing for solar.

Our team seeks to create a singular place to live, work and pursue all that urban life in Manhattan offers. A sustainable project unique in all the country that will inspire the architectural and development community to expand their notions of urban affordable housing to see the possibilities of healthy sustainable projects notable for their cultural life and energy, not their problems.

Inspiration from community gardeners

We have taken our inspiration from the community gardeners, who take abandoned lots strewn with trash and make a place where nature can flourish. In much the same way, on the vacant the E111 site, inhabited by feral cats and rat poisoning warnings we dream of building a village - that simplest of urban gathering places where the old mingle with the young, where the street life runs through the alleys, tumbles in to the yard and then spills back onto streets. In our project we let the sun in to shine in our windows, to warm us and nourish our plants, and as a source of power for our residents. We cherish the rain and capture it to cool to nurture our garden spaces. The initial architectural concept was to conceive of the site as a complete mass built fully within all of the street walls


Integrated Design Process: Passive House As Design Inspiration

Passive House design informed some of the earliest and most important design decisions on the project. These early shading/massing studies helped define the massing concept of the project. By creating a void or 'solar wedge' at the Southeast corner of the site, the project achieved the dual goals of maximizing passive solar gains on southern facades and creating light filled commuity garden. The shading studies also defined the approach to fenestration and shading.

Green Features

E111 will be the largest Passive House Project in the country once completed. Open source concept sharing will help make E111 a model and demonstration for future Passive House implementation across NYC. Building tours and community outreach will further educate and spread the word to the public.

The proposed project for SustaiNY is the largest passive house project in the country. The proposed approach would be an open source concept paving the way for future passive house projects in NYC. A few key green features include: cogeneration, bioswales, rainwater harvesting, farmers markets, green roofs, and solar PV system with battery storage for resilency.
