What is a Passive Home?

As concerns about climate-change and resource-depletion continue to grow, innovative solutions are emerging to transform the way we build and inhabit our homes. One such groundbreaking concept is the passive home, an approach that redefines energy efficiency and sustainable living.

What is a Passive Home?

A passive home is not just a house – it is design and engineering at its best, prioritising comfort, health, and energy efficiency. At its core, a passive home is designed to maintain a consistently comfortable indoor environment while using minimal energy for heating, cooling, and ventilation. It achieves this through a combination of focused design, modern materials, and advanced technologies.


Key Principles of Passive Homes

  1. Thermal Insulation: Passive homes are built with exceptional thermal insulation, which prevents heat from escaping during colder months and keeps the interior cool during hotter periods. This advanced insulation is far superior to that of regular homes.
  2. Airtight Construction: Unlike conventional homes that might have air leaks and drafts, passive homes are constructed to be airtight. This prevents the uncontrolled exchange of indoor and outdoor air, reducing the need for mechanical heating or cooling.
  3. High-Quality Windows and Doors: Passive homes feature windows and doors that offer superior insulation with minimal thermal bridging. This plays a vital role in maintaining consistent indoor temperatures.
  4. Mechanical Ventilation with Heat Recovery (MVHR): Passive homes are equipped with mechanical ventilation systems that ensure a continuous and controlled supply of fresh air, while recovering heat from the outgoing stale air. This maintains optimal indoor air quality and reduces the need for additional heating.
  5. Passive Solar Design: The orientation of a passive home takes advantage of the sun's energy for heating during the colder months. Large north-facing windows allow sunlight to enter and warm the interior naturally.


Benefits of Passive Homes

  1. Energy Efficiency: The primary advantage of a passive home is its remarkable energy efficiency. It uses up to 90% less energy for heating and cooling compared to a conventional home, resulting in significantly reduced utility bills.
  2. Comfort: Thanks to the airtight design and superior insulation, passive homes offer consistent indoor temperatures, free from drafts and cold spots.
  3. Improved Air Quality: Mechanical ventilation systems with heat recovery ensure a constant supply of fresh air, contributing to a healthier indoor environment.
  4. Environmental Impact: By minimizing energy consumption, passive homes contribute to a more sustainable future.
  5. Long-Term Savings: While the initial cost of a passive home might be slightly higher, the long-term savings on energy bills and maintenance make it a cost-effective investment.


The Future Beckons

Passive homes represent a paradigm shift in the way we approach residential architecture. They blend leading technology with timeless design principles to create spaces that are comfortable, environmentally conscious, and financially prudent.

As our world continues to grapple with the challenges of climate change, passive homes offer hope and an example of a more sustainable future in housing.

Whether you're an eco-conscious individual, a homeowner looking to minimize energy bills, or simply someone fascinated by innovation, passive homes are a concept worth exploring. Welcome to the future of sustainable living!

Sustainable Extras


Either transfer or add-on your preferred solar energy solution to your completed EvoCo after installation, or let us know what you require and we will arrange for solar to be included in your installation. Our homes are significantly lower cost to power than a conventional home so the energy savings provided by solar will keep your running costs to a minimum.

Rainwater Collection

Rainwater collection or harvesting is another popular sustainability solution for homeowners today. You can collect rainwater as a potable supply for your home, or simply use it to irrigate your gardens.  


Mechanical Ventilation with Heat Recovery (MVHR) systems provide fresh filtered air into your home whilst retaining 90% of the heat from the outgoing air. This heat is typically generated from your oven, heated towel rails, hot showers and the general running of TVs and appliances among other heat sources.  

Interior Design Options

From selecting cork tiles to organic cotton curtains, water-based paints or upcycled furniture, we can work with you to make your EvoCo home more sustainable by selecting other products or solutions during the Interior Design process.
