Building Facade Consultancy, Advisory Services 

Why Facade Consultants?

Facades are becoming increasingly complex as architects are pushing the limits of creativity and coming up with a diverse array of geometrical features. Facade work amounts up to 20% of overall construction cost, is a potentially high risk element in successful building completion. Facade system comprises a series of interdependent and sometimes conflicting requirements, has stake on overall building performance such as weather tight, resist wind, control amount of light enters in to building, reduce heat gain, provide natural ventilation, control incoming noise, fire safety and more...

Envelopetechnik Facade Consultancy has rich experience with complex facade systems for low-rise, high-rise and super-tall buildings, enable us to provide best possible advice. Designing a facade system encompasses structural engineering, building physics, materials science, weatherproofing technology, architectural detailing, construction management and many other disciplines. We have proven track record of bringing professional facade specialists with required experience, skill and technology. Sharing and collaboration are essential at all stages of a project’s life cycle. Envelopetechnik has expertise in BIM (Building Information Modeling)  and adopted BIM (Building Information Modeling) throughout all stages of design and documentation enabling it to reduce project cost, improve productivity, reduce conflicts and changes, avoid rework. We work closely with material suppliers, fabricators , facade contractors having in-depth understanding of their performance track record in terms of infrastructure, financial, quality and delivery, enable us to provide expert advice while making key decisions. 

Engaging a specialist consultant during early design increases success in achieving design, budget and performance expectations. Envelopetechnik Facade Consultancy has rich experience with complex facade systems designed for low-rise, high-rise and super-tall buildings, applied to numerous projects, helps to develop an envelope design that "works" for the life of the building.  Envelopetechnik provides an honest, independent solutions that works in the best interests of client and project.
