Blowhouse Location: Mornington Peninsula, Victoria, Australia With climate change globally, the average temperature increased and sea level raise. It a challenge to consider how to survive the environment. Blow house is a life support unit, which imagine the future dwelling. Based on CFD (Computational Fluid Dynamics) analysis the intensities of wind velocity and pressure onto the site and the house. Wind flow is used to generate form which is sustainability and reduce the high-pressure concentrations onto the envelop. Envelope 4

Cape Schanck House Location: Location: Cape Schanck, Victoria, Australia The house is near coastline subject to strong prevailing wind. It sits within an expanse of native trees site. The form finding is based on the sun analysis and simulate the wind force, speed, and direction in site. By optimizing, the house emerges organically in some symbiotic relationship with the land.

Since the climate change, architects start rethink the relationship between architecture and environment. A series of Life Support Unit aim to design sustainability future dwelling by patterns in nature and the kinetics of the environment. Life Support Units are carbon forms and climate forms which through the new design culture towards a new order of forms. This semester I got an interesting practice experience. The design approach attracts me. Architecture closed relate with the existing surrounding context. The local climate is considered early in the conceptual stage of design. PMA speculate the design first and then speculate the site. Site research plays an important role in design process. For this project, the air flow becomes a visible element creating the architectural form through the close observation and analysis of the air motion. Optimization also can help the building gain the natural ventilation. Although gradual, the changes in the environment patterns are also noticeable and impactful to architectural design. Optimization designing enables to discover the optimal architectural shape based on specific weather data. Architecture as a dynamic element placed in the environment, it will be able to fit into and influence the ever-changing surroundings. The optimization architectural design based on the specific climate conditions helps to test different design options to find an optimal placement of buildings, an optimal building’s shape or an optimal material to be used to benefit from the environment factor and to improve it using architecture. In more extreme environments, this design principle is applicable and even required. Architecture creates an artificial environment that basically competes with the natural environment. It is also one reason of climate change and global warm. So, sustainable architecture from the envelope and orientation consider the adaptability and energy efficiency. Compare with Roland Snook’s Studio workflow. Roland’s studio focus on investigate the biology and nature behaviours and quality. Then, the biology quality transform to the architecture language. Later to consider its printable. However, PMA pays attention on the study the patterns in nature and the kinetics of the environment. In terms of the series research apply the climate data to optimize the envelope. In terms on explore the conflicts and complexities by combine the parametric design and the natural context. Compare with another structure optimization method. CFD is a form structure optimization, which simulate the wind velocity and pressure. Using these data as the reference to optimize the bluff body. For Ameba optimization is totally different with it. The key strategy is based on a simple algorithm. Which gradually removes inefficient materials in the structure and “evolves” into the optimal result, which can be used for design inspiration. They are the totally different form finding system. Ameba is from the engineering aspect to consider the loading and material to optimize the form integrally. However, CFD in terms on the environment kinetics to simulate the nature pattern on the architecture. Although they are form funding technique, the purpose is different. One is approaching efficient design outcomes another is focus on sustainability design outcome.

3.0 New Typologies 3.3 CFD Modeling (Computational Fluid Dynamics Modeling) RE-MASK A large amount of masks were consumed in the past three months. Facing with the growing survival crisis and unexpected disasters, human may need to be more adaptive. Insipred from bio-form, Re-Mask is an external skeleton of body generated from BESO topology optimization with alternative filters for different situations. It could be a solution for furture survival challenges.
