from concept to construction
The building envelope is a functional and complex living surface. It fulfills a diversity of aspects, such as: aesthetics and representation, communication, safety and regulation of the external climate for attaining interior comfort. Every single project defines a specific mix of thermal, acoustic, fire and ventilation performance requirements. Bringing these together with the architectural design is the aim, and it requires not only a profound knowledge of established façade types, but also the willingness to develop façade concepts beyond classic typologies.
Our input to this process is the evaluation of external and internal conditions of the building location, in order to propose a façade and ventilation concept that meets the project’s artistic and functional intentions without sacrificing quality and performance.
We believe that new materials, information technologies and construction methods allow architects and engineers to develop new façade solutions in order to optimize resources and construction time.
from form to material
We create innovative engineering concepts to support ground-breaking architectural proposals. Complex geometries require analysis and rationalization to facilitate the design process and to develop a cost-effective assembly strategy. Our Performative Building Group transfers the surfaces and structures designed into digital representations, taking into consideration materials and structural behavior amongst other project-related issues.
The materialization of the design is the point where the façade starts to live. Our experience in glass design and alternative materials enable us to develop new structural façade concepts, optimizing the material quantity and, as a result, its dimensions.
from building physics to green skins
B+G consultancy also provides recommendations for reaching the envelope’s thermal requirements considering the following issues:
Interaction between thermal, acoustic und structural design, integration of requirements for a sustainable holistic design, incorporation of energy standards, life cycle assessment and ecological accounting, life cycle-oriented design of components, incorporation of requirements for international certification systems (LEED, BREAAM, DGNB, BNB, Passive house, ESTIDAMA, HQE, among others).
from comfort to efficiency
Solar energy which impacts and in places passes through the façade should be controlled to regulate heat gains and improve the visual comfort of interior spaces. We calculate the daylight factor and illuminance of interior and exterior surfaces, leading to optimization of artificial and natural lighting.
Solar radiation or wind flow can be taken into consideration as parameter for shape design. Single- or Multi-criteria-Design is used to balance a complex network of requirements.
From samples to real performance
We advise on the execution of standard physical tests for a full-scale façade mock-up, to accurately assess the weather- and structural performance of the façade system (including envelope design, fabrication and installation) and consequently ensure a superior quality of the whole building.
Some of these tests are: air tightness, static water tightness, dynamic water tightness, soft- and hard body impact.
from recycling to continuity
The refurbishment of a building’s envelope provides not only an exceptional opportunity for a new face but also for an upgrade of its performance, which is important at least for energy savings and often also for occupants’ health and comfort.
Historic listed buildings need to be carefully preserved and improved in a balanced way. B+G Façade’s consultants have the expertise to create such high-quality multifaceted façade concepts.
