The Building Component Award recognizes innovation, performance, and sustainability in building components. It highlights products and technologies that enhance living comfort, improve energy efficiency, and durability in buildings. Organized by the Passive House Institute as part of a European Union–funded project and the winners will be honored during the International Passive House Conference.

Retrofitting plays a central role in climate protection and energy efficiency strategies, yet it remains a challenge when it comes to technical feasibility and cost. This is particularly true for window replacements in existing buildings, which often face barriers in planning, logistics, and execution. With this award, the Passive House Institute invites manufacturers, system providers, craftsmen, and interdisciplinary teams to rethink how Passive House windows can be integrated into existing façades with minimal disruption, high energy performance, and smart prefabrication strategies. The aim: practical solutions that simplify the retrofit process and demonstrate that step-by-step renovation using high-performance components is not only possible – but scalable.

The registration period for the 2026 Component Award has ended and we will publish the result soon!

Award ceremony
The winners will be honored at the International Passive House Conference 2026 in Essen, where the best solutions will be presented and added to the Passive House component database. Participants who use certified products can also qualify for the EnerPHit component seal.

In recent years, excellent progress has been made with reference to the thermal quality of windows.In order to make a significant contribution to climate protection, these further improved windows must enter the global mainstream. To create an impetus and contribute to accelerate the uptake of windows that represent the cutting edge in terms of thermal efficiency, the Passive House Institute has conducted this award as part of the AZEB-Project, supported by the European Union. Window manufacturers from all over the world took part in the award: 3 companies from 12 countries took part in the competition with 31 products and variants. The jury awarded 10 regular prizes and 4 special prizes.

In 2018 for the second time running the Component Award was awarded for ventilation solutions for residential buildings. The housing sector is once again experiencing steady growth after years of stagnation. The current Component Award was concentrated on cost-effective ventilation solutions for new residential constructions. A multi-storey building consisting of differently sized apartments with living areas between 50 and 100 m² was to be equipped with an overall ventilation system. We were looking for solutions with both low investment costs and a high level of energy efficiency.

Ventilation with heat recovery is indispensable for energy efficient construction and retrofitting. In existing buildings, this becomes necessary either before or by the time the windows are replaced, with the associated improvement of airtightness. A well thought-out overall concept is essential in the process, with a compact duct network, low-cost devices and flexible installation solutions. All these aspects were diligently examined during the assessment of the submitted entries for the Component Award, in each case with a critical eye on the life cycle costs.

The main challenge in the Component Award 2015 for Passive House windows was that the product had to show a degree of flexibility since refurbishments are often carried out in a step-by-step manner. Ideal windows had to deliver excellent results during the transitional period as well as after the completion of all refurbishment measures. The cost effectiveness of the windows was assessed first and foremost, with a comparison of purchase costs with potential savings. The award is presented on 17 April at the International Passive House Conference 2015 in Leipzig.

The winners of the first ever Passive House Component Award have been selected and a total of eleven Passive House windows received a recognition. The real winners, however, are the building owners, for the results of this international competition demonstrate that it is possible to save money with highly efficient building components. Manufacturers offered their products at retail prices including installation for an example building. For each of the four categories, “PVC,” “Wood,” “Wood/Aluminium,” and “Aluminium,” the overall investment and energy costs saved in comparison with standard windows were the decisive factor. The Award was presented at the International Passive House Conference from 25 to 26 April 2014 in Aachen, Germany.
