At Stoneweg US, environmental sustainability plays a key factor in creating the best apartment communities for our residents.  Stoneweg US is committed to implementing sustainable practices that are pragmatic and achievable. We have successfully reduced our environmental footprint by repositioning older multifamily assets (rather than demolishing and rebuilding) and by developing new high-performance multifamily projects with a focus on reducing waste, energy and water use.


Given that many multifamily communities are older and are less energy efficient or have fewer sustainability features, there is a prime opportunity to improve sustainability and add value to our assets. Our water and energy conservation programs have significantly increased the environmental efficiency of our assets, while improving our residents’ quality of life and maximizing returns for our investors. In addition to reducing utility consumption, Stoneweg US is also focused on waste reduction. Those strategies include recycling programs at most properties in the Stoneweg US portfolio.

The Stoneweg US environmental sustainability goals are to:

  • Reduce current water consumption 15% by 2022

  • Reduce current energy consumption 20% by 2022

  • Invest in clean and renewable energy generation technologies, reducing emissions

  • Invest in green technologies that reduce energy and water use
