*지속가능한 시카고 연구소 [ GO Logic ] houses University of Chicago laboratory

지속가능한 건축환경을 지향한다. 건축스튜디오 , GO Logic가 디자인한 시카고 연구소는 에너지 절감형 하우스로 미시간의 풍부한 자연환경을 투영한 건축공간으로 구현된다. (외장재는 친환경 적삼목 판넬을 이용 마감) 이러한 건축환경은 시카고 생태학, 진화학과를 위한 교육 및 연구공간으로 숲과 초원의 자연환경에 적용가능한 타입폴로지로 제안된다. -주변 생태환경과의 공존을 첫번째로 목표로 한다.- 이 연구소는 메인 필드 스테이션과 3개의 캐빈(오두막) 그리고 한개의 화장실로 구성된다. 필드 스테이션에는 연구 실험실과 세미나실이 위치하며 12명의 손님이 숙박할 수 있도록 오두막이 숲을 따라 배치된다.

건축의 지향점은 앞서 말한 것과 같이 최소한의 인공성(최소한의 자연훼손)을 바탕으로 패시브 하우스 구축을 목표로 한다. (패시브 솔라 에너지 활용과 높은 단열환경을 기본으로 소량의 에너지 소비를 유도하는 건축환경) 여기에 실험실에서 사용된 잉여분의 열에너지를 히트 트랜스퍼 덕트를 통해 건물 내부로 재분배 한다. 이는 겨울철 효율적인 열에너지 운영을 가능케 하며 자연채광, 자연환기와 함께 연구소의 안정적인 패시브 환경을 구축한다.

This energy-efficient laboratory by architecture office GO Logic is clad in pale cedar to reference agricultural buildings found close to its site in a remote forest clearing in Michigan.
The Warren Woods Ecological Field Station was designed by Maine-based GO Logic to accommodate the University of Chicago's department of ecology and evolution, allowing researchers to spend time in an ecologically diverse habitat that includes different types of forest and prairie.

The site harbors several types of habitat currently under ecological restoration, including lowland hardwood forest, climax beech-maple forest and remnant-wet prairie," said the architects.
"The field station allows research on biodiversity, evolutionary trajectories, genetic characterisation and ecological interactions between species in this habitat as well as botanical experiments in fenced test plots."
The complex comprises a main field station building, three cabins and a bathhouse.
A research laboratory and educational seminar spaces are contained in the field station, while the smaller structures situated along the edge of the forest provide overnight accommodation and amenities for up to 12 visitors.
A key concern for the designers was to minimise the ecological impact of the buildings and achieve a Passivhaus low-energy certification, which involved optimising passive solar gain and incorporating highly efficient insulation.
Excess heat from the laboratory equipment is distributed throughout the building by heat transfer ducts, to keep the interior warm in winter.
An airtight shell helps to retain this warmth, while the optimisation of natural light and ventilation reduces the use of artificial alternatives.
"The design approach for the field station was to create a compact, highly insulated building shell that makes use of passive solar gains, resulting in a highly energy-efficient facility that will realise tremendous energy savings over the life span of the building," said the architects.
The building's position on the site is determined by the requirement to make the most of the natural light. The laboratory is situated on the northern edge to reduce its solar exposure and prevent overheating.
Solar glazing along one side of the main seminar space is shaded by hinged steel sliding screens fitted to the exterior, which enable the amount of light entering the interior to be controlled.
The vertical boards used to clad the buildings are made from locally harvested untreated cedar that will gradually take on a silvery tone similar to barns found in the surrounding area.
Internal materials were selected to be robust and lasting, with the polished concrete floor slab also providing a thermal mass that helps to regulate the interior temperature throughout the year.
Ash boards cover a layer of acoustic installation applied to the underside of the sloping ceiling, adding a warm complement to the concrete and white walls.
A glass wall with a fritted white gradient separates the seminar space from the laboratory.
"The frit pattern transitions from solid at the bottom of the wall, to transparent at the top," said the architects.
"This gradient allows a strong visual connection from the lab back to the classroom space at eye level, while providing a visual barrier to the cluttered work surfaces in the laboratory space," they added.
The staircase that connects the ground floor with a seminar room and roof deck on the upper storey features open treads and a perforated metal screen.
Group meals can be cooked in a kitchen in the field station and eaten in a glazed sun porch that looks out towards the cabins and the forest.
