Contribute to more housing in cities

We take into account the great challenge of housing for all, by offering cement and concrete solutions, along with innovative processes and services that help everyone find a home under the best possible conditions in the heart of our cities.

Our contribution

Through support of Habitat for Humanity to durable solutions for assisted living centers, we contribute research and innovation to residences large and small.   Our offer includes:

 

  • Cement and concrete solutions that can be used to build new homes and restore existing ones.

 

  • Innovative processes and services to build homes faster and at low cost. Thanks to our partnerships, we have developed innovative concrete-based methods, such as stay-in-place formwork.

 

And to allow the option of housing at low cost, particularly in developing countries, we have invented solutions to provide:

 

  • Easier access to our materials. For example we have found a way of delivering concrete into the heart of busy downtown areas.

The Lafarge Group has made these commitments to contribute to better housing as part of our "Sustainability Ambitions for 2020", a program we launched in June 2012: "Enable 2 million people around the world to have access to affordable and sustainable housing through the development and introduction of innovative solutions."

 

 

 

Canada: the first net zero energy precast concrete homes

In Edmonton, Canada, two homes could be the start of a new thinking for quick, affordable and durable buildings: they are the first in the country to be designed and built in precast concrete and to achieve zero net energy consumption! In addition, these houses made in Lafarge concrete host two families in need of a hand-up selected by Habitat for Humanity.

 

Two families chosen by Habitat for Humanity in Edmonton, Alberta, Canada, have been handed the keys of their one-of-a-kind duplex homes. They are indeed the first precast concrete houses in Canada to be designed and built to achieve zero net energy consumption!

 

As they are located in Canada, you might expect them to be built primarily in wood. No! These houses developed by Lafarge Canada in partnership with the NGO Habitat for Humanity and the engineering firm Stantec, are made of concrete, which plays a huge role in the houses' environmental performance.

 

Concrete, the Key for Energy Efficiency

The two duplexes take advantage of the mass of concrete, which retains heat from the daytime sun and releases it during the night. By combining its thermal properties with photo voltaic solar panels on the roof driving a geothermal heat pump for heating and cooling, the homes should produce as much energy as they consume over a year! As icing on the cake, concrete makes the houses more fire and sound-resistant than standard residences.

 

For this special project, our teams delivered two kinds of concrete:

 

  • precast slabs for an air-tight and energy efficient building envelope;
  • ready-mix for the duplexes' footing and basement floor slab, and for a layer of topping over the precast hollow core slabs.

 

This type of construction could meet the growing demand for strong and energy-efficient homes in Edmonton and other cities. Lafarge has already applied lessons from the duplex to new assisted living and mid-rise multifamily projects.

 

NetZero Precast Concrete Duplex Wins 2013 Project of the Year

The NetZero Precast Concrete Duplex project in the Riverdale community of Edmonton is the winner of Alberta Construction Magazine's Top Projects Awards' Project of the Year and is also the winner in the Sustainability category.
