Abstract

To give future generations the ability to meet their own needs, our built environment needs to excel rather than endure. The need for continual improvement calls for fewer passive houses and more active houses - buildings that adopt a responsible and sustainable attitude as not just zero energy consumers but net energy producers, reaching a positive energy balance over time. Materiality is a fundamental element of such a discussion, and wood an obvious protagonist as a carbon store that substitutes for fossil fuel-intensive alternatives such as steel and concrete. Prefabricated timber claddings can be treated or finished or furnished or devised with different products and features that assist with turning the building into a net energy producer, and aligning the study with Rolf Disch's concept of the PlusEnergy solar house allows for a conceptual toolbox of sustainability objectives that can be translated into our innovative wooden cladding systems. That translation process is carried out using the strategy, borrowed from evolutionary biology, of optimising design iterations within a fitness landscape using evolutionary solvers. The aim of the study is to showcase prototypical design development studies backed up with raw data in the form of simulations, tests, and analyses to begin to answer the question of how TimesEnergy timber cladding systems can be turned into a feasible and sustainable alternative in the production of multistorey timber buildings. ; Godkänd; 2014; 20141023 (andbra)
