Conception and Realization from one source *

GAP1 engineering creates ideas and designs for energy-optimized buildings; combines expert knowledge; is a competent partner; accompanies you - through all realization phases, from conception to implementation.


Integratred Processes

GAP1 engineering stands for close collaboration of architects, planners and executors as well as for the careful coordination of building-physical and energetic conditions. This combination ensures integrated processes and smooth work flows – and clever solutions. 

Precise Implementation

Based on a comprehensive collection of facts, we develop an energy-optimized construction and management concept, which we will implement precisely and efficiently. In doing so, we combine solid craftsmanship with industrial production and the special GAP system. 


Perfected Know-How 

In Europe-wide cooperation with universities and research institutions, GAP1 engineering constantly develops new ideas for practical use – inventive spirit with the know-how from R&D. 

Customized Concepts 

Based on these ideas and proven components, GAP1 engineering realizes custom-made solutions – each project is unique.  

Optimized Processes

With its 20 years of experience, GAP1 engineering systemizes and optimizes all processes – all under one roof for you. 


Refurbishment and New Construction 

We upgrade. GAP1 engineering converts your building into a modern property that keeps its value on a passive house level. Thermal rehabilitation is based on the GAP facade system. 

We construct from scratch. GAP1 engineering implements energetically optimized holistic solutions for your new house – on a technical level that will still be first class in 20 years!
