Abstract
The building envelope has a key role to play in achieving indoor comfort for the occupants and building energy efficiency. A dynamic, active and integrated solution -- able to achieve the optimum thermal performance, harness energy from renewable resources and, integrate active elements and systems -- is the most promising and innovative strategy for the building envelope of tomorrow. To achieve an effective and sustainable building envelope with a dynamic behaviour, considerable efforts in research and development are necessary. This paper endeavours to present a broad review of design, research and development work in the field of Dynamic Adaptive Building Envelope (DABE). Based on detailed studies, the characteristic features, enabling technologies, and the overall motivations that have tendered to the advancement of DABE are discussed. In spite of its positive aspects, the study reveals that the concept of DABE has not yet been well-applied and needs much more exploration. Various challenges need to be resolved and advanced research undertaken to bring it to maturity and acceptance.
Highlights
Since the Stone Age, human beings have sought shelter that would protect them from the external environment and offer comfort conditions
Dynamic Adaptive Building Envelope (DABE) is a nomenclature used in building science and engineering to include the roofs and the façades which relate with their variable environment in a dynamic way [4]
There are numerous other examples for the Dynamic Adaptive Building Envelope like the Conservatory buildings in Gardens by the Bay (2012) in Singapore, designed by Wilkinson Eyre; the One Ocean pavilion in Yeosu, South Korea designed by SOMA from Vienna, Austria; Storefront for Art and Architecture in New York (1993), designed by Steven Holl and Vito Acconci; the Communications and Design building for Syddansk Universitet in Kolding, Denmark designed by Henning Larsen Architects; the Kiefer Technic Showroom in Bad Gleichenberg, Austria designed by Ernst Giselbrecht + Partner, etc
Summary
Since the Stone Age, human beings have sought shelter that would protect them from the external environment and offer comfort conditions. The concern was safety and security but soon it was realised that this shelter can be an effectual measure to achieve thermal comfort inside To improve this function, it became necessary to focus on the building envelope considering the fact that this building element, which further consists of a set of components, separates the outdoor from the indoor. The building envelope, or ‘skin’ as it is known as, is that part of the building which encloses space, separating the inside from the outside It, comprises those elements which are constructed to divide the internal from the external environment and, consists of structural materials and finishes and include doors, windows, walls, floor surfaces, and roofs -- the transparent as well as the opaque elements. We have facilities for appropriate designing of building envelopes that canreject or accept free energy available from the external environment, thereby reducing the costs required to achieve a comfortable, internal environment [9]
