At Passivhaus Design Services, we provide specialist consultancy and design support for low-energy, high-performance buildings that meet the rigorous Passivhaus standard. Our services are focused on delivering buildings that achieve exceptional energy efficiency, superior comfort, and minimal environmental impact.

Passivhaus design is a proven approach to construction that significantly reduces heating and cooling demand through high levels of insulation, airtightness, and advanced ventilation systems. By applying these principles from the earliest design stages, we help clients create buildings that are both sustainable and cost-effective to operate over the long term.

How Much Do Passivhaus Plans Cost with Passivhaus Design Services?

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

The cost depends on the size, complexity, and type of project. Smaller residential projects may fall at the lower end, while large commercial or multi-unit developments require more detailed modelling and coordination, resulting in higher costs.

Pricing is influenced by factors such as the level of modelling required, number of design iterations, certification support, and project scale. While initial costs may be higher than standard design services, Passivhaus projects offer significant long-term savings through reduced energy consumption.

What Does Passivhaus Design Services Include?

Passivhaus Design Services provides a comprehensive range of consultancy and design support:

• PHPP modelling – Detailed energy modelling using Passivhaus Planning Package software
• Thermal bridge analysis – Identifying and reducing heat loss points
• Airtightness strategy – Designing for minimal air leakage
• Ventilation design – Mechanical ventilation with heat recovery (MVHR) systems
• Energy performance optimisation – Reducing heating and cooling demand
• Certification support – Guidance through the Passivhaus certification process

Each service is tailored to ensure the project meets strict Passivhaus performance criteria.

What Is The Passivhaus Design Process by Passivhaus Design Services?

The process begins with an initial consultation to understand the project goals, site conditions, and desired level of energy performance. Early-stage design input is then provided to optimise building form, orientation, and fabric performance.

Detailed energy modelling is carried out using PHPP software to predict building performance and ensure compliance with Passivhaus criteria. Design elements such as insulation, windows, airtightness, and ventilation systems are refined to achieve the required standards.

Throughout the project, ongoing support is provided to coordinate with architects and contractors, ensuring that the design is implemented correctly. Final documentation and testing are completed to support Passivhaus certification where required.

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

Passivhaus Design Services supports a wide range of energy-focused developments:

• Residential homes – New builds and self-build Passivhaus homes
• Housing developments – Multi-unit low-energy housing schemes
• Schools and educational buildings – Energy-efficient learning environments
• Commercial buildings – Offices and mixed-use developments
• Retrofit projects – Upgrading existing buildings to EnerPHit standards

Each service is tailored to meet the energy and performance goals of the project.

How Quickly Can Passivhaus Reporting Be Delivered by Passivhaus Design Services?

Passivhaus design services are delivered over several weeks to a few months, depending on the complexity of the project and the level of design input required. Early-stage assessments and initial modelling can often be completed within one to two weeks, while full design support continues throughout the project lifecycle.

Passivhaus Design Services works efficiently to align with project timelines while ensuring all design elements are thoroughly developed and compliant.

How Does Passivhaus Design Services Ensure Compliance?

Passivhaus Design Services ensures compliance by following the strict criteria set out by the Passivhaus Institute. This includes meeting targets for energy demand, airtightness (typically ≤0.6 air changes per hour), and thermal comfort.

All designs are supported by detailed PHPP calculations and documentation, ensuring that performance targets are met and certification requirements are satisfied. This ensures buildings achieve recognised standards for energy efficiency and sustainability.

When Do You Need Passivhaus Consultancy by Passivhaus Design Services?

Passivhaus design services are required at the early planning and design stages of a project, particularly when aiming to achieve Passivhaus certification or significantly improve energy performance. Early involvement is essential to ensure that key principles such as building orientation, insulation, and airtightness are fully integrated into the design.

These services are commonly used for new builds, residential developments, schools, and commercial buildings where energy efficiency and sustainability are key priorities. They are also valuable for refurbishment projects aiming to meet EnerPHit standards, the Passivhaus equivalent for retrofits.
