Blocks and Spots, LLC is pleased to announce that we are now certified to work on Passive House Building Enclosures and Services.

We’re committed to building for the future and not just today. With the costs of utilities going up, along with the cost of maintenance, it’s important to find ways of making the structure of a house work harder.

Definition of Passive House

A passive house (or Passivhaus) is a building standard focused on achieving high energy efficiency and thermal comfort. This design significantly reduces a building’s carbon footprint and energy consumption.

Key Features

Energy Efficiency

• Ultra-Low Energy Use: Passive houses require very little energy for heating or cooling.
• Near-Zero Energy Consumption: Achieved through superior insulation and airtight construction.

Thermal Comfort

• Consistent Indoor Temperatures: Maintains comfortable temperatures year-round without relying heavily on traditional heating or cooling systems.

Construction Principles

• Airtightness: The building envelope is sealed to prevent air leaks.
• High-Quality Insulation: Continuous insulation throughout the structure minimizes heat loss.
• Efficient Windows and Doors: Designed to reduce thermal bridging and enhance energy performance.
• Heat Recovery Ventilation: Systems that recover heat from exhaust air to pre-warm incoming fresh air.

Global Adoption

• Worldwide Certification: As of January 2025, over 47,400 units have been certified globally, with significant growth in North America and other regions.
• Diverse Applications: Used for residential and non-residential buildings, including offices, schools, and healthcare facilities.

Historical Context

• Origin: The concept began in the 1970s, evolving into a formal standard in the 1990s, primarily developed by Wolfgang Feist and Bo Adamson.
• First Examples: The first buildings to meet this standard were constructed in Darmstadt, Germany, in the early 1990s.

Passive houses represent a sustainable approach to building design, aiming for energy efficiency and occupant comfort while minimizing environmental impact.
