Sustainable Ideas

Earth Day 2017


Education is the foundation for progress. We need to build a global citizenry fluent in the concepts of climate change and aware of its unprecedented threat to our planet. We need to empower everyone with the knowledge to inspire action in defense of environmental protection. Environmental and climate literacy is the engine not only for creating green voters and advancing environmental and climate laws and policies but also for accelerating green technologies and jobs.

This Earth Day, gather with your community for an Environmental & Climate Literacy Teach-In or another project focused on education. We are launching Earth Day and Teach-In toolkits that will lay out the steps for holding a successful event. Register your event with us and we will support you with promotion and advice.


“We take time to give back to the people.”


Sustainable Architect and Urban Planner Wolfgang Frey Takes an Unconventional Approach to Building with People and their Individual Needs in Mind.

„We take time to give back to the people.“ Wolfgang Frey is convinced, as were his great-grandfathers, that a person’s responsibility for buildings and the people living in them lasts a lifetime and beyond. Time, like energy and water, is a resource that shouldn’t be wasted.

Reforestation Project in Taiyuan, China


Human existence has an enormous influence on nature. Our meat consumption, the use of daily transportation, energy, gas and water all contribute to environmental pollution. Even our breathing – and that of animals – emits CO2. It is an enormous contemporary issue that everyone should be aware of. Architects have found a solution to this problem by building passive houses. Houses built according to passive house standards emit less carbon dioxide, which in turn saves the environment. But no matter how well we build something – in the end the act of construction itself creates CO2. Manufacturing construction materials such as clay tiles that are burnt at 1.000 degrees Celcius contributes to climate change. A polemic solution would be to simply stop building altogether. Given our ever-growing world population, however, that’s not really an option.

Wolfgang Frey, a practicing architect who specializes in sustainability in Freiburg, has found a better option for ironing out his „debt“. In the spring of 2014 Mr. Frey began a reforestation project on the Chinese mountain Xishan (which means West Mountain in English) in Taiyuan in the Chinese province Shanxi. Wolfgang Frey has planted over 6,000 trees on 12.4 acres. Every growing plant absorbs CO2.


Handicapped Accessible Public Bathroom Facilities in Heidelberg Village


The new urban development project Bahnstadt in Heidelberg appeals through its innovative implementation of ecological and social goals to ensure a high standard of living for all residents.

At the same time a public bathroom facility will be built on the ground floor of Heidelberg Village to meet the demands of people with special needs. The general contractor and project developer Freie Liegenschaftsverwaltung GmbH from the Frey Group thereby enables the integration and consideration of everyone’s needs.


Biweekly Free Lunch for Everyone at its Heidelberg Village Construction Site


Whoever said there is no such thing as a free lunch?

Every other week they offer a free lunch to bring both worker and home dweller closer together.
