# What Are the 5 Passive House Principles?

## Short Answer

The 5 Passive House principles are insulation, airtightness, high-performance windows, mechanical ventilation, and thermal bridge-free construction, all working together to create a high-performance home.

## Overview

Passive House is a globally recognised building standard focused on comfort, health, and energy efficiency. Rather than relying on heating systems, it focuses on reducing the need for them in the first place.

## Key Points

- High levels of insulation keep heat inside during winter and outside during summer.
- Airtight construction prevents uncontrolled air leakage and draughts.
- High-performance windows reduce heat loss and improve solar gain.
- Mechanical ventilation with heat recovery provides fresh air while retaining warmth.
- Thermal bridge-free design eliminates weak points where heat can escape.
- Each principle supports the others. If one is missing, overall performance is reduced.

## Common Questions

**Do I need all 5 principles?** Yes, they work as a complete system.

**Is Passive House common in NZ?** It is growing, but still not standard practice.

**Can I apply some principles without certification?** Yes, many homes adopt these ideas without formal certification.
