An exhibit in Berlin details a new prototype for prefab housing

A new exhibition at Architektur Galerie Berlin SATELLIT details the Polish firm BBGK Architekci and their recently completed Sprzeczna 4 apartment building in Warsaw, Poland. Manifesto of Prefabrication, on view through Saturday, September 29, explains why this multifamily complex is an innovative prototype for modular housing in the country. Most housing estates built in Poland during the communist period feature large-panel concrete in prefabricated designs. This typology is ubiquitous throughout the country, especially in the capital city of Warsaw, and it has a poor reputation for being ugly, impersonal, and unsustainable. BBGK constructed Sprzeczna 4 in protest against this conception and to show that prefabrication is a valuable construction method for 21st-century housing. The complex utilizes low-cost technology, prefabricated elements, and heated ceiling systems to achieve a cohesive, contextually appropriate design. Ample light infuses the apartments through large windows framed by exposed colored concrete. Sprzeczna 4 not only flips stereotypes about traditional modular construction in Poland, but it also sheds light on past improper building practices. Historically these buildings were built by poorly paid immigrants through a semi-feudal system, but BBGK implemented fair business practices and social responsibility to create this contemporary twist on conventional Polish housing. According to the curator, Marcin Szczelina, the project is a proposal for a new way of using the prefabrication method not only in Poland, but in Europe and beyond. Manifesto of Prefabrication can be seen this week only at the Architektur Galerie Berlin SATELLIT. It is open Tuesday to Friday from 2 p.m. to 7 p.m., and Saturday from 12 p.m. to 6 p.m.

This tiny ultra-efficient PassivHaus was built in just ten days in Australia

Known for being economical in terms of space and sticker price, prefabricated homes are also boasting increasingly abbreviated build times. One modest-sized dwelling in Castlemaine, Australia took a mere 10 days to construct and garnered an esteemed sustainability marque from PassivHaus to boot. One of the world’s fastest-growing energy performance standards, ‘Passive House’ accreditation is doled out solely to homes operating on 90 percent less energy than traditional homes. For consideration, three eco-friendly parameters are paramount: thermal performance, airtightness, and ventilation. The most efficient homes use the sun, internal heat sources, and heat recovery for insulation, avoiding the need for energy-guzzling radiators even in the icy throes of winter. At just 419 square feet, the Passive House in Castlemaine, Australia (the first in the country to receive this certification) comprises a wooden frame with wool and fiber insulation and a facade clad in steel to confer a modern look. Further insulation comes from the triple-glazed windows and specially engineered seals protecting the windows and floors, which is made from an air-tight membrane called Intello. Keeping the interior snug and toasty year-round is an energy recovery system which, contrary to ordinary logic, funnels air into the house, heating it in the winter and cooling it in the summer at low running cost while also keeping moisture out. The system also tamps down heat transfer, giving the exterior of the house a u-value (heat transfer coefficient) of 0.261 watts per square meter. The lower a home’s u-value, the better its insulation. As a result, annual heating, electricity and hot water demands for the Castlemaine Passivhaus are a mere 11 kilowatt hours per square foot. Designed by Australian architectural firm CARBONlite, which specializes in prefab homes, the various sections of the Castlemaine dwelling were built off-site over a 5-day period. Once assembled on site, the exterior was erected and the building made wind and watertight that same day. The house has a mono pitch roof with an overhang to provide shade and minimize overheating during Australia’s scorching summers.
