Passive House Trailblazers: Embracing the Future of Energy-Smart Architecture

As the world continues to strive for more sustainable living, one architectural concept that has gained considerable attention in recent years is the Passive House. These energy-smart homes are designed to maximise comfort and minimise energy consumption, making them an increasingly popular choice for homeowners and Architectural Designers alike. In this article, we’ll delve into the advantages of Passive Houses, answer common questions, and explore a stunning example of a Passive House new build project – Cooper’s Farm (see image).

The Advantages of a Passive House

The Passive House concept revolves around five key principles: superior insulation, airtight construction, high-performance windows, ventilation with heat recovery, and minimising thermal bridges. Together, these principles help to deliver numerous benefits:

Reduced energy consumption: Passive Houses require 75-90% less heating energy than traditional homes.
Enhanced comfort: Consistent indoor temperatures and excellent air quality create a comfortable living environment.
Long-term cost savings: Lower energy bills more than offset any initial investment in passive house design and construction.
Eco-friendly: Passive Houses contribute to reducing greenhouse gas emissions and conserving natural resources.
Improved health: High-quality ventilation systems help to reduce allergens and pollutants, promoting better health for occupants.

Your Questions Answered

Are passive houses expensive to build?

While building a passive house can have a slightly higher upfront cost than a conventional home, the long-term savings on energy bills make it a worthwhile investment. Certified passive house designers can help you create an affordable passive house plan that maximises efficiency without breaking the bank.

How much does a passive house cost UK?

The cost of building a passive house in the UK varies depending on factors such as location, size, and materials used. On average, the cost can be between £1,500 and £2,000 per square metre. However, the potential long-term savings on energy bills often outweigh the initial investment.

What are the best walls for a passive house?

Passive House walls should provide excellent insulation and airtightness. Common materials for Passive House walls include insulated concrete forms (ICFs), structural insulated panels (SIPs), and double-stud walls with high-performance insulation.

How thick should walls be for passive house?

The ideal wall thickness for a Passive House depends on factors such as climate, insulation materials, and construction techniques. Generally, Passive House walls can range from 300mm to 600mm in thickness to ensure optimal energy efficiency.

How much heating does a passive house need?

A Passive House is designed to require minimal active heating. In the UK, the average Passive House needs just 15 kWh/m² per year for heating, compared to 100-150 kWh/m² per year for a standard home.

Cooper’s Farm: A Passive House Masterpiece

One standout example of a Passive House project is Cooper’s Farm (see image), an exquisite home that showcases the best of energy-smart architecture. The timber frame construction provides a sustainable and efficient building material, while the cantilevered first floor creates a unique aesthetic. A Sussex hip roof adds a touch of traditional charm to this innovative design.

By working closely with a certified passive house designer, the homeowners were able to create a comfortable, energy-efficient, and visually striking home that exceeded their expectations.
