At Passivhaus Design, we provide expert low-energy building design services focused on creating highly efficient, comfortable, and sustainable structures. Our approach follows the internationally recognised Passivhaus standard, ensuring buildings achieve exceptional performance in terms of energy use, thermal comfort, and indoor air quality.

Passivhaus design is centred on reducing energy demand through high levels of insulation, airtight construction, and advanced ventilation systems. By integrating these principles from the earliest stages, we help clients deliver buildings that require minimal heating and cooling while maintaining a consistent and comfortable internal environment.

With a strong commitment to sustainability, innovation, and quality, Passivhaus Design is a trusted partner for clients looking to achieve exceptional building performance and reduced environmental impact.

How Much Does Passivhaus Planning Cost with Passivhaus Design?

The cost of Passivhaus design ranges from £2,000 to £15,000+.

The cost depends on the size, complexity, and type of project. Smaller residential designs will generally fall at the lower end, while larger developments or projects requiring full certification support will require a higher investment.

Costs are influenced by the level of modelling required, design iterations, and coordination with project teams. While initial costs may be higher than standard design approaches, Passivhaus buildings offer significant long-term savings through reduced energy consumption.

When Do You Need Passivhaus Consultancy by Passivhaus Design?

Passivhaus design is required at the earliest stages of a project, particularly during concept and planning phases, where building form, orientation, and fabric performance can be optimised. Early involvement is essential to ensure all key principles are incorporated effectively into the design.

It is commonly used for new builds, residential developments, and commercial projects where energy efficiency and sustainability are key objectives. Passivhaus design is also suitable for retrofit projects aiming to significantly improve the performance of existing buildings.

What Does Passivhaus Design Include?

Passivhaus Design provides a full range of services to support high-performance building design:

• Energy modelling (PHPP) – Detailed performance calculations using Passivhaus software
• Thermal performance design – High levels of insulation and reduced heat loss
• Airtightness strategy – Minimising uncontrolled air leakage
• Ventilation design (MVHR) – Mechanical ventilation with heat recovery systems
• Thermal bridge analysis – Eliminating weak points in the building envelope
• Certification support – Guidance through the Passivhaus certification process

Each design is carefully developed to meet strict Passivhaus performance targets.

What Is The Passivhaus Planning Process by Passivhaus Design?

The process begins with an initial consultation to understand the project goals, site conditions, and energy performance targets. Early design input is provided to optimise building orientation, layout, and fabric efficiency.

Detailed energy modelling is then carried out using PHPP software to assess performance and guide design decisions. Key elements such as insulation, windows, airtightness, and ventilation systems are refined to meet Passivhaus standards.

Throughout the project, ongoing support is provided to ensure the design is correctly implemented. Final documentation and testing are completed to confirm performance and support certification where required.

What Types of Projects Benefit from Passivhaus Design by Passivhaus Design?

Passivhaus Design supports a wide range of energy-efficient developments:

• Residential homes – Self-build and high-performance houses
• Housing developments – Multi-unit low-energy schemes
• Commercial buildings – Offices and mixed-use projects
• Educational facilities – Schools and learning environments
• Retrofit projects – Upgrading existing buildings to high performance

Each design is tailored to meet the specific performance goals of the project.

How Quickly Can Passivhaus Design Be Delivered by Passivhaus Design?

Passivhaus design services are delivered over several weeks to a few months, depending on the complexity and scale of the project. Initial modelling and concept design can often be completed within one to two weeks, while full design support continues throughout the project lifecycle.

Passivhaus Design works efficiently to align with project timelines while ensuring all design elements are fully optimised and compliant.

How Does Passivhaus Design Ensure Compliance?

Passivhaus Design ensures compliance by following the strict criteria set by the Passivhaus Institute. This includes meeting targets for energy demand, airtightness, and thermal comfort.

All designs are supported by detailed PHPP calculations and performance modelling, ensuring that buildings meet certification standards where required. This guarantees that the final structure achieves a high level of energy efficiency and sustainability.
