PLUG-IN + 

is a holistic, all-electric retrofit design approach for triple deckers that prioritizes resilient systems, locally available labor and materials, and minimal resident disruption. 
Utile worked with Haycon, Resonant Energy, and Structures Workshop to deliver this comprehensive product design.

PLUG-IN+ has four main elements:

I. outside-in envelope upgrades for thermal comfort and energy efficiency
II. air tightness measures and balanced energy recovery ventilation for enhanced air quality
III. cost optimized rooftop solar PV to offset electricity usage
IV. an exterior mechanical systems plug-in

The “plug-in” is a small addition that elevates the building’s ventilation and water heating systems out of the basement for flood resilience, and it can be customized for each site to provide additional benefits like bike storage, outdoor seating, and composting.
