How to make houses greener

Vernacular techniques and local materials are becoming more and more relevant in architecture.

Building a cheaper, greener house: the geodesic dome – and the prefab.

.

There are a lot of innovative ways to make buildings ‘greener’.

MATERIALS:

The increasing use of wood is clearly sustainable:

Indeed, using local materials make very good sense:

Although if you are going to import building materials, they can still be pretty sustainable:

Today’s Arch Daily has an interesting piece on upscaling traditional building materials and technologies:

Vernacular techniques and local materials are becoming more and more relevant in architecture, but is it possible to bring these concepts to large urban areas?

In 1984, the Amazonian architect Severiano Porto had already pointed out the need to make architecture more connected to its location. Using local materials and techniques is becoming more important each day, considering the impacts of the commodity chain of building construction on the planet. Not surprisingly, the number of projects that use this approach is growing every day

Given the outlook for the future of our planet, we must consider changing the way we build cities and occupy our land. Therefore, we should focus on integrating natural materials with techniques that are available and affordable in big cities, as seen in the “Heart of Yongan” Community Center / TJAD and the Grotto Retreat Xiyaotou Residencial Village / A( )VOID. However, we should also pay attention to the process, choosing the methods and materials that have a lower impact on the environment, both locally and globally.

PREFAB:

Prefabricated or modular homes can be very green indeed – as with a recent project in East Devon:

In fact, there are some great, innovative ideas becoming practical reality:

Futures Forum: A solution to our housing problems: CLT > cross laminated timber

Futures Forum: A solution to our housing problems: offsite manufactured homes

With the Passivhaus normally using a lot of prefabricated elements:

And it’s happening in these parts too:

Indeed, as another piece from Arch Daily points out, prefab can be not only cheap, but be of real quality – and with quite a pedigree:

This idea is by no means new. Architects such as Frank Lloyd Wright, Le Corbusier, Jean Prouvé and Walter Gropius have developed several projects to effectively integrate housing construction with this industry. Specifically, the latter deserves to be highlighted for his efforts on the subject: the publication “The Dream of the Factory Made House”, by Walter Gropius and Konrad Wachsmann, edited by MIT Press, provides an overview of the experiences of the two German architects, their achievements and their many setbacks. The Packaged House System, developed by the two, is a prototype whose ingenuity attracts attention, developed after World War II, which can expand or reduce as needed, but unfortunately, did not survive commercially.

And the geodesic dome from Buckminster Fuller is catching on as the modular home:

Cheap to build, heat, cool, and maintain, the geodesic dome, originally designed by Buckminster Fuller, just may be the log cabin of the 21st century.”

MORE GREEN IDEAS:

There are lots of ways ahead, in fact – for example:

Urban mining: recycling buildings – Vision Group for Sidmouth

Decarbonising buildings – Vision Group for Sidmouth

And this even more important than ever:
