KTS | Elsworth Show Home

The Project

Kingspan Timber Solutions delivered this contemporary new show home to our client Potton. The new show home is constructed using the Kingspan TEK Building System and is the UK's first show home built to Passivhaus standard.

HTA Design

The Design

Part of the motivation for constructing the home was to dispel the myths often associated with Passivhaus builds - for example, not being able to open the windows, the air inside being unhealthy and the ventilation system being noisy and expensive to run.

With innovative features which are visually exciting and technically challenging, the sustainable show home, which was designed by HTA Design LLP, demonstrates what can be achieved without the need to compromise on style or design.

The new show home has nearly double the amount of insulation and is approximately ten times more airtight than a property which just complies with current building regulations.

Achieving the requirements of the Passivhaus standard can be a challenge. It often leads to the architectural design of the building to be compromised in order to offer the most energy efficient form, typically resulting in a design that sacrifices interest for simplicity. Potton and HTA Design wanted to demonstrate that it is not necessary when a high performance construction system is used. We purposely selected the design which would be the most complex to build from an energy efficient perspective as it offered the most flexible family home. The result is a testament to the high levels of building performance and architectural design that can be achieved with careful planning, expert workmanship and the right products.

We have used the Kingspan TEK Building System on hundreds of low-energy buildings and trust and understand its performance characteristics. From experience, we knew that by carefully sealing and taping the external wall junctions that we could achieve the airtightness required for a Passivhaus level construction. After carrying out two tests, including a smoke test to reveal leaks, we attained a final result of 0.43 ach (air changes per hour) @ 50 Pa, exceeding the standard's minimum of 0.60 ach @ 50 Pa.
