Passive House – Design & Certification Process

Published: 6th November 2020

So, you’ve decided that you want to self-build and go down the Passive House certified route. The certification is often known in the industry as ‘Passivhaus’, but for the benefit of this article, we shall call it by it’s UK moniker.

A home built for the future with many key advantages over your typical new build home including low running costs, longevity and sustainability benefits.

Here at Econekt, Passive House building is in the DNA of everything we do, with an unrivalled system to have your home designed and constructed to the high and prestigious building standard.

Design Process

When designing your home, it is imperative that all relevant parties have a sound understanding of Passive House building standards and principles. This is to ensure that these are integrated into the design process from the very beginning as if they are not, you could find yourself in trouble later in the build with some issues potentially rendering your home unable to achieve certification.

Passive House Planning Package (PHPP)

When designing your certified home, it is key that you use the Passive House Planning Package, otherwise known as PHPP. This is a comprehensive yet easy to use planning tool for Passive House building. The reliability of the tool’s calculations is hailed by planning experts and architects up and down the country.

A powerful tried and tested planning tool, the PHPP has been continually developed since its introduction in 1998. Its key features include tools to calculate annual and monthly space heating values, heat distribution and supply, and electricity and heating demand.

Passive House School Certifications

We partner with Passive House School in order to offer you certification for your new self-build. They offer the reputable certification using the PHPP, a stamp of quality assurance that ensures a building meets the high performance and comfort levels of a Passive House home’s standards.

The Certification Process:

There are several stages to getting your home certified with ourselves and Passive House School.

First, there would be an initial review of the home’s design in line with Passive House standards. Drawings, specifications, calculations and other documents are reviewed in order to make sure they meet Passive House standards.

Next, a report is compiled, drawing attention to any potential threats to achieving your certification.

Finally, a post-construction documentation review will be conducted and your certification is then awarded, provided the home meets all requirements. If for some reason your home did not meet the requirements then the defects would be outlined and provided they can be resolved, your project could then be resubmitted for another assessment.

Thermal Bridging

Occurring when heat or cold transfers across the external surface of a building, causing either heat to leave the structure, or vice versa. Logic would dictate that thermal bridging is not conducive to achieving Passive House standard certification for your self-build projects, and you would be correct for thinking this. Thermal Bridging is a problem that all self-builders face, and it’s how you deal with the issue that defines whether or not your project can achieve certification.

What does Econekt do to prevent Thermal Bridging?

Through the development of Econekt’s complete structural building system and the integration of Izodom ICF as the key component, we are able to offer a system that, if adopted and detailed from the start, has the ability to simply remove the risk of thermal bridges at each of the key building junctions. Something we are very proud of.
