AM Envelope: The Potential of Additive Manufacturing for facade constructions
The continuous development of the building envelope over the past hundred years can be exemplified by a few ground-breaking inventions. Firstly, the separation of primary and secondary structure during the beginning of the 20th century; by implementing a curtain wall façade to physically separate the façade from the building. This was followed by the development of double façades and a growing technologisation and use of the building envelope for building services and climate devices. Hereby the development of the ‘Polyvalent Wall’ by Mike Davies at the beginning of the 1980ies was a notable vision that formulated part of the building envelope as an active skin. The realisation of such a concept of a compact building envelope that encompasses all necessary supply units and building services in a very slender and integrated way has still not been accomplished. This vision has been followed by many technical developments; the latest being based on decentralised building services that are inseparably connected to the façade. But in spite of all these efforts, even forty years after Mike Davies‘ vision we are far from their realisation. Therefore, realising a ‘dynamic building envelope’ is a goal yet to be achieved. One technology to materialise this desire is Additive Manufacturing (AM): Layered production of parts from a 3D file. Over the past twenty years this technology has evolved from a support tool for product development into an independent production method. The term ‘AM Envelope’ (Additive Manufacturing Envelope) describes the transfer of this technology to the building envelope. Additive Fabrication is a building block that aids in developing the building envelope from a mere space enclosure to a dynamic building envelope. AM Envelope is an approach to this evolutionary step with the AM technology. This is exemplarily concretised and illustrated with building components for a post-beam façade, and then transferred to façade development over the next thirty years. This dissertation shows the potential of the additive methods for the development of façade construction: Additive methods change the way we design, build and produce building envelopes.Architectural Engineering + TechnologyArchitectur

Lightweight bonded acrylic facing at the Vitra VSL Factory
Acrylic glass is omnipresent in the industrialised world; but as a building material most architects, facade planners and engineers are still unfamiliar with this material. In most cases it is applied as a substitute for glass which leads to inappropriate joints and fixtures. During the years of the path toward the digital era, the authors were in the fortunate position to be involved in several unconventional glass and acrylic glass projects. On the basis of their most recent project, the facade of the Vitra VSL Factory by SANAA Architekten, they describe the development of a facade for which they chose acrylic glass not as a substitute for glass but rather as a conscious material choice. Since the entire facade is it was possible to apply the manufacturing technology of deep-drawing, allowing for very thin wall thicknesses.Architectural Engineering +TechnologyArchitecture and The Built Environmen

Acoustically effective facade
Today’s city centres in European metropolitan areas are comprised of facades made of steel, glass and stone. These hard reflective facades are amplifying the perception of noise sources by human ears in their vicinity. Up to now in building designs this effect is neglected. Thus the number of people harmed by noise is increasing with the increasing noise levels on the streets caused by more and more hard reflective facades. To obtain control on urban acoustic spaces the focus of architects and engineers must be shifted to acoustics parameters. Several case studies in course of this research give evidence for the possibility of controlling the impact of noise sources on an urban space with modified facades. The experience and results of the case studies were merged to deliver a plot of a process chart for implementing the acoustical point of view in a building design process. Laboratory methods e.g. scale model measurements and impedance measurements were modified in order to be feasible in a building or facade design process. As with modified reflection properties of facade surfaces a sound reduction of up to 8 dB for specific frequency bands is feasible the building of quieter cities is in the responsibility of architects and engineers.A+BE | Architecture and the Built Environment No. 16 (2018)Design of Construtio
Updated urban facade design for quieter outdoor spaces
The increasing migration into cities leads to an increasing number of people stressed by noise. More and more people are moving into urban settings comprised of multiple noise sources and hard reflective glass and steel facades. The omnidirectional arrangement of noise sources like airborne noise or car traffic noise and their reflection on the facades neither composes urban arrangements with silent indoor areas nor comfortable quiet areas outdoor. To come up with requirements for silent areas inside and outside of buildings further design parameters have to be introduced. The facade is not only a shelter for the inside it can also provide comfort spaces outside the building. As engineers and architects we cannot change the noise source, but we can influence the impact on the surrounding urban space by controlling the reflection of noise emissions on the urban surfaces like facades. In a facade design the capability of reflecting noise can be tuned by modifying the surface. In order to come up with the acoustical needs no radical new way of facade design has to be introduced. Mainly a shift of attention to the acoustic parameters is needed. Based on acoustic measurements of basic geometry principles this research presents known facade designs and their acoustic parameters regarding the reflection capabilities and the functions in a facade.Design of Construtio
