Overview: A two-part look at the architecture and engineering of a 217-unit affordable housing project as it pushes toward net zero.
Presentation 1: Going the Last Mile: Getting to Net Zero in Dense Urban Environments
The Jennings Hall Expansion not only sought to add 217 all-electric units of senior affordable housing wrapped in a 14-story Passive House enclosure in East Williamsburg, Brooklyn, but also to push toward net-zero goals, all while constrained by a dense urban site and a nearby subway tunnel. Critical to crushing overall energy use was tackling domestic hot water, ventilation, heating, and cooling with integrated solar, hydronic, and ERV systems.
Learning Objectives:
- Explore Passive House design and its applicability to address environmental justice goals for vulnerable populations.
- Compare MEP selection with a focus on pairing renewables (geothermal, solar) as it relates to operation and embodied carbon.
- Discuss the potential and challenges of integrating BIVP for multifamily housing.
- Explain the challenges and strategies for achieving net-zero performance in urban multifamily buildings.
Presentation 2: Hydronic Energy Balance for the Win
At Jennings Hall Expansion, a 217-unit affordable housing development, in addition to the many architectural and façade elements intended to reduce energy consumption, the HVAC and Domestic Hot Water Systems were designed to use water-source heat pumps coupled with a ground-source geo-exchange (geothermal) system that leverage multiple zones and diverse uses to further dramatically reduce energy use and carbon emissions.THe approach offers a way to minimize the negative impacts of VRF refrigerants and realize the energy savings that ultra-low-energy Passive House buildings are designed to achieve.
Learning Objectives:
- Describe the advantages of using water-source heat pumps.
- Explain the benefits and advantages of coupling domestic hot water.
- Describe the advantages of utilizing a geo-exchange (geothermal) system.
- Identify advantages in both energy reduction and global warming mitigation.
