The Mieles Supportive and Affordable Housing

EP Engineering collaborates with Amie Gross Architects to provide full MEP engineering services for new Supportive and Affordable Housing project developed by the not-for-profit organization Transitional Services for New York, Inc. (TSINY). The building is located in Jamaica, Queens. It will serve as an important staple for many vulnerable members of the local community; TSINY will provide affordable housing and supportive care when the building is complete for low-income seniors and those struggling with homelessness. Other partners in the project include the New York City Department of Housing Preservation and Development (HPD) and Community Preservation Corporation (CPC).

When complete the building will be 8-stories tall, 46,000 square feet and will consist of 68 residential studio units. On-site counseling and administrative services, community based recreational activities and an outdoor garden space will be available to the residents. Construction of the building is anticipated to be complete sometime in 2022.

Engineering challenges

  • Bringing a pre-2020 Mechanical system design up to new Ashrae recommendations for building ventilation systems, published as a result of the COVID-19 pandemic.
  • Provide sufficient fresh air to residential units where the residents will spend much of their time.

Engineering outcomes

  • Helped present and explore better air quality options to the client to make an informed decision based on the current Ashrae recommendations at the time. The mechanical design was revised to incorporate higher grade filters, increased ventilation air and supplemental air purifiers.
  • Provided rooftop ERV units to provide tempered ventilation air via heat exchange with residential exhaust. (4) ERV’s were provided to localize ductwork to logical apartment stacks and limit duct crossing.
