SHIRASU BLOCKS, PRODUCED BY COMBINING THE REGIONAL VOLCANIC ASH AND CEMENT ARE USED IN THE BUILDING DESIGNED BY ARAY ARCHITECTURE. Shirasu Evi, Asei Suzuki tarafından 2009’da kurulan Aray Mimarlık’ın tamamlanan ilk ev projesi. Suzuki kendi mimarlık firmasını kurmadan önce Tokyo merkezli Hiroshi Nakamura & NAP şirketinin tasarım direktörü olarak cam-tuğla bir cephe ardında ağaçlıklı bir avlu ve sanat galerisini kapsayan ve alan ve ışığı vurgulayan benzer bir ekolojik ev projesinde çalışmış. Kagoşima bölgesinde yer alan iki katlı Shirasu Evi, altı kişilik bir aile için tasarlanmış. Müşteri ısıtma ve soğutma için çevre dostu pasif doğal sistemlerin kullanıldığı enerji verimli bir iç ortam talebiyle gelince, çözüm volkanik Shirasu toprağı, taş ve çimentodan oluşan tuğlaların üretiminde 70 NATURA • MART - NİSAN 2014 / MARCH - APRIL 2014 T he efficient use of stone in construction requires a combination of technical and scientific knowledge. Different types of stones exhibit a range of reactions over time that affects the durability of the stone blocks and building units and hence the building. To understand the complex interactions that stone in construction has with it’s near environment (the building) and the macro environment (the local climate and atmospheric conditions) it is necessary to understand the physical properties of the stone used in each project such as its density/hardness, thermal transfer and moisture convection properties. These characteristics, once understood, are able to drive the design process to create architecture that respects the conditions of building and opens up the potential for advanced architecture. Aray Architecture of Japan has pursued this line of thought in their design for a house in Japan’s southernmost island Kagoshima. The geography here is an area of seismic and volcanic activity typical throughout Japan. As a result of this volcanic action over the millennia, the geology of Kagoshima consists of layers of volcanic soil and stone called Shirasu. This layer of stone and sand became the inspiration and material basis for the architecture strategy used by Aray for the Shirasu House project completed in 2013. Specifically architect Asei Suzuki of Aray Architecture formulated a way to locally produce bricks for the walls of the house that were made by combining volcanic ash soil and gemstone rocks with cement. These bricks became the primary design feature of the house visible on both the inner and outer layers of its double wall construction. These rectangular bricks used in horizontal bands across the surfaces of the building provide the house with its aesthetic impact while generating crucial ecologic performance.
