Comments Off on Architects experiment with terracotta in the fight against climate change

Architects have drawn on terracotta for thousands of years – but are now exploring combating climate change with the ancient building material . Ceramicists, engineers, and architects converged on Buffalo this year for the Architectural Ceramic Assemblies Workshop (ACAW) to investigate environmentally responsive terracotta designs . Terracotta is durable, breathes, offers a natural system to transfer water and heat, lasts for hundreds of years, and can be sculpted, transforming buildings into artwork, according to the University at Buffalo (UB). ACAW participants came together to work on terracotta facade prototypes with an emphasis on bioclimatic design. Workshop co-organizer and UB chair of architecture Omar Khan said in a statement, “Buildings account for two-thirds of final energy use and more than half of the world’s greenhouse gases . Yet the materials and assembly methods used for building facades have remained essentially the same since the 1950s. The skin of architecture must adapt to and mitigate such changes in our environment. Bioclimatic design invites us to change the paradigm from disposability to longevity.” Related: Brilliant zero-energy air conditioner in India is beautiful and functional Four research teams developed prototypes during the four-day workshop. Team UB/Alfred designed a terracotta shingle system with digital sculpting techniques that supports passive cooling . Team AECOM created a terracotta counter-current heat exchanger able to channel heat throughout a building using little to zero energy. A team from structural engineering and design firm Walter P. Moore explored a post-tensioned system of terracotta panels to answer questions on insulation, heating and cooling , and thermal mass and ventilation, as well as how different composite formulations would boost terracotta’s structural possibilities. And Team Morphosis worked on a facade system with ribboned terracotta panels for natural ventilation and evaporative cooling , while creating the feeling of movement. UB said the teams “are expected to advance results into full-scale projects, patented products, and actual buildings.” + Architectural Ceramic Assemblies Workshop Via the University at Buffalo Images via Douglas Levere, University at Buffalo (1,3); Alexander Becker (2,4); and Laura Garófalo (5)

Comments Off on Super-insulated modern log cabin withstands frigid Finnish winters in style

Winters in Finland can plunge to a freezling -22 degrees Fahrenheit, but those chilling temperatures are no match for this well-insulated log cabin. Crafted by Helsinki-based company Pluspuu , this Log Villa on the Coast was commissioned as a client’s second home on the Turku coast. The light-filled abode harnesses geothermal energy for heating and cooling, and boasts superior insulation as well as triple-glazed windows. Built by Ollikaisen Hirsirakenne Oy with the latest Finnish log construction technology, this modern log villa is a custom, site-specific build that gave rise to one of Pluspuu’s newest house models, the Kustavi 125. Topped with a mono-pitched metal roof, the 125-square-meter two-bedroom home is raised off the ground and wrapped in black-stained glue-laminated timber . Black-painted aluminum window frames surround the large triple-glazed windows. Two covered terraces extend living space outdoors.

Sweeping landscape and sea views can be enjoyed from the open-plan living room, kitchen, and dining area, as well as from the sauna . For insulation, the architects used 202-millimeter-thick laminated log walls and 500-millimeter-thick wood fiber insulation for the roof. Pluspuu (Finnish for “plus wood”) provides high-quality log houses in a variety of models and promotes the use of timber as a “breathable material with indisputably positive health effects.” + Pluspuu Via ArchDaily Images © Samuli Miettinen
