The 22-square-meter Tiny House

UN Environment and Yale University — in collaboration with UN-Habitat — unveiled a new eco-housing module to spark public discussion and new ideas on how sustainable design can provide decent, affordable housing while limiting the overuse of natural resources and climate change.

 

The 22-square-meter "tiny house” is fully powered by renewable energy and designed to test the potential for minimizing the use of natural resources such as water.

 

The Ecological Living Module, unveiled during the United Nations High-level Political Forum on Sustainable Development, is constructed primarily from locally-sourced, bio-based renewable materials. The first demonstration unit is on view in the UN Plaza in New York City through July 18.

 

The Yale Center for Ecosystems in Architecture worked with Gray Organschi Architecture to design, fabricate, and install the Ecological Living Module. The unit is efficient and multi-functional, accommodating up to four people, serving both domestic and commercial purposes.

 

"We clearly need more housing, but the key thing is that we also need smarter housing” said Erik Solheim, head of UN Environment. "The housing sector uses 40% of the planet’s total resources and represents more than one-third of global greenhouse gas emissions. Making them more efficient will benefit everyone, and it will mean lower bills, too. Innovations like the Ecological Living Module are what we need more of.”

 

"Adequate housing is at the heart of sustainable urbanization,” said Maimunah Mohd Sharif, executive director of UN-Habitat. "The use of proper building materials, better planning, and improved construction techniques can make energy use in buildings more efficient. If adopted widely, this practice can create jobs and prosperity with lower greenhouse gas emissions.”

 

Engineered to operate independently, the module’s built-in systems include solar energy generation using less than 1% of toxic semiconductor materials, on-site water collection, micro agricultural infrastructure, natural daylighting, plant-based air purification, passive cross-ventilation, and a range of flexible, adaptable components for living and working.

 

About 1 billion people worldwide currently live in informal settlements, while millions more live in buildings that are not environmentally friendly, note the officials. Rapid urbanization and economic growth challenge communities to sustainably expand capacity, heightening the need for innovation in building systems and infrastructure, they say.

 

"Architecture must address the global housing challenge by integrating critically needed scientific and technical advances in energy, water, and material systems while remaining sensitive to the cultural and aesthetic aspirations of different regions,” said Deborah Berke, dean of the Yale School of Architecture.

 

The demonstration unit in the UN Plaza contains features relevant to the local climate and context of New York. Future iterations of the module — including one in Kenya, the home of UN Environment — will respond specifically to local climatic and cultural contexts.
