In the quest for constructing energy-efficient and sustainable buildings, the choice of building materials plays a pivotal role. One such material that stands out in the realm of Passive House construction is Structural Insulated Panels (SIPs). In this blog post, we delve into the compelling reasons why building a Passive House with SIPs is a strategic and advantageous choice.

Built-In Airtightness:

One of the standout features of SIPs is their inherent airtightness. SIPs are manufactured with precision, providing a seamless and consistently airtight building envelope. This characteristic significantly reduces the likelihood of air leakage, making it easier to achieve and confirm compliance with the stringent airtightness criteria set by the Passive House standard. This inherent airtightness minimises the room for error during construction, ensuring a robust and energy-efficient building shell.

Simplicity Equals Success:

Constructing a Passive House with SIPs is often deemed foolproof due to its simplicity. You ‘only’ have to seal the joints between the panels and any joints between the panels and the flooring.  Of course, you will also have to seal all penetrations. But the panels come pre-insulated and ready for assembly, requiring fewer intricate details to be drawn during the design phase. This simplicity not only streamlines the construction process but also contributes to a more efficient workflow for architects/ designers and builders alike.

Reduced Thermal Bridge Calculations:

SIPs significantly ease the workload for Passive House consultants, particularly in the realm of thermal bridge calculations. Unlike traditional construction methods that may involve numerous thermal bridges, our SIPs projects typically require only 2 to 4 thermal bridge calculations, compared to 10 – 14 on other projects. This streamlined approach not only expedites the certification process but also contributes to the overall cost-effectiveness of the project. Please note, depending on the complexity of the design you might indeed have many more thermal bridge calculations.

Time and Cost Savings:

The efficiency gained from using SIPs translates into notable time and cost savings. With fewer details to draw, simplified construction processes, and fewer thermal bridge calculations, projects involving SIPs can be completed more swiftly compared to traditional construction methods. The inherent airtightness of SIPs also contributes to long-term cost savings through reduced energy consumption.

Proven Track Record:

We at Gruen have done several successful sips passive house projects. Projects utilising SIPs consistently meet and exceed Passive House criteria, showcasing the material’s ability to deliver high-performance, energy-efficient buildings.

In conclusion, the decision to build a Passive House with SIPs is a strategic one that aligns with the principles of efficiency, precision, and sustainability. The inherent airtightness, simplicity, reduced thermal bridge calculations, and associated time and cost savings make SIPs a smart choice for developers and designers committed to constructing high-performance, eco-friendly buildings. Embrace the future of construction with SIPs and witness the seamless integration of cutting-edge technology and sustainable design.
