Water, Waste, and Renewable Energy

You can use Portfolio Manager to manage energy, water, and waste, as well as track your renewable energy. Once you’ve benchmarked your building, use the EPA resources below to identify opportunities to save water, improve waste management, and purchase or install renewable energy.

Save Water

Check out the WaterSense website to find certified products and best management practices for many types of commercial buildings.

For best practices on managing and reducing facility water use, download WaterSense at Work: Best Management Practices for Commercial and Institutional Facilities (PDF, 5.5 MB) or check out no-cost live and recorded training webinars on water-saving topics.

Reduce Waste

Office buildings, schools, stores, hotels, restaurants and other commercial and institutional buildings generate significant amounts of waste material. Check out tools and resources to help facility managers, building owners, tenants and other stakeholders improve waste management in their buildings, reduce costs, and enhance sustainability.

Install or Purchase Renewable Energy

Thinking about installing a renewable energy system at your building, like solar arrays or a wind turbine? Increasing the energy efficiency of your building is a smart way to prepare for installing onsite renewable energy systems. Efficiency upgrades can shrink the energy load of your building by 30 percent or more, which will allow you to maximize the proportion of clean power generated on-site at the least cost. In other words, energy efficiency gives you the most bang for your renewable energy buck.
