Commitment To Sustainability

We believe every home should be healthy, energy-efficient, and built to last. Our mission is to create renovations that deliver measurable performance, enhance comfort, and minimize environmental impact—building a more resilient future, one home at a time.

What Defines A Passive House?

Passive House is a rigorous, performance-based standard for energy-efficient buildings—characterized by five core principles.

1.
Super-Insulated Envelopes

2.
Airtight Construction

3.
Passive Solar Design And Shading

4.
Balanced Heat-Recovery Ventilation (HRV/ERV)

5.
Minimal Active Heating And Cooling Systems

Passive House Perks

Passive-inspired design delivers real environmental value in historic NYC townhomes, including healthier indoor air, lower energy use, and quieter living. 

Performance by Design

We embed sustainable strategies into every renovation—not as a separate add-on, but as part of how we design and build.

  1. Early energy modeling to guide decision-making

  2. High-performance windows and insulation

  3. Mechanical ventilation with heat or energy recovery (HRV/ERV)

  4. Efficient, all-electric systems

  5. Thermal bridge-free detailing and long-lasting materials

DNA of a Passive House

To reach a Passive House level of performance, most homes require a full renovation, including:

  • Envelope upgrades (walls, roof, windows, insulation)

  • Airtight detailing between floors, walls, and rooflines

  • System updates for heating, cooling, and air exchange

  • Interior reconfiguration to support passive performance

The reBuild Experience

In every Passive House renovation, reBuild Workshop combines architecture, interiors, and construction with performance. We want every corner of your home to contribute to a smarter, more sustainable result.
