Goal:

Solutions for Passive House design standards

Corona Senior Residences is a 57,675 sf, 8-story 68-unit affordable housing apartment building for low-income seniors, designed to meet the NYSERDA Multifamily Performance Standards for Energy Star Certification as well as the Enterprise Green Communities Criteria.

It and will also be the first affordable senior housing development in the United States to meet the Passive House Institute (PHI) design standards. The ground floor of the building will be designated to an early childhood education facility to be administered by the New York City School Construction Authority.

System

The building HVAC system is comprised of small energy-recovery ventilators and variable refrigerant flow fan coil units in each apartment. Ventilation in the education facility and the apartment common areas and corridors is provided by large energy recovery air handlers.

Requirements:

The Passive House consultant sought to provide ventilation meet local code requirements, using devices meeting Passive House Institute requirements for:

high heat recovery effectiveness
high electrical efficiency
low casing leakage
low cross-contamination
self-balancing control

Solution:

Swegon provided (2) GOLD RX 07 air handling units with heat recovery, both exceeding the minimum requirements for PHI certification:

Passive House Institute Certification Criteria	Passive House Institute Minimum Performance	Passive House Institute Certified Performance Swegon GOLD RX 07
Heat Recovery Effectiveness	>75%	85.5%
Electrical Efficiency	<0.765 W/CFM	0.68 W/CFM
Casing Leakage	<3%	0.45%
Cross Contamination	<3%	0.45%
Self-Balancing Control	Return Air automatically reset to be within 10% of the supply air	Self-balancing control is a standard feature within Swegon’s GOLD Control System (IQ Logic)
