“Green infrastructure” in urban and suburban areas — that is, techniques such as green roofs, tree plantings, rain gardens and permeable pavement, which absorb rainwater near where it falls — is proven to help solve major water pollution problems. These water management practices store rainwater for use, evaporate it back into the atmosphere or let it filter into the ground, where it can benefit vegetation and replenish groundwater supplies.
Many communities around the U.S. now rely on green infrastructure as a cost-effective solution to stormwater infrastructure problems. What’s more, these communities reap the added benefits of beautifying neighborhoods, cooling and cleansing the air, reducing asthma and heat-related illnesses, reducing energy demand for heating and cooling, and creating “green-collar” jobs.
Less well-known — but vitally important — is that green infrastructure on private property can provide a wide range of benefits to commercial property owners and their tenants.
Green infrastructure benefits
A new NRDC report released today, "The Green Edge: How Commercial Property Investment in Green Infrastructure Creates Value," details the following benefits, which help to build the business case for commercial real estate owners to invest in green infrastructure:
• Increased rents and property values
• Increased retail sales
• Energy savings
• Local financial incentives (such as tax credits, rebates, and stormwater fee credits)
• Reduced infrastructure costs
• Reduced flood damage
• Reduced water bills
• Increased health and job satisfaction for office employees
• Reduced crime
Real dollar values can be put on many of these benefits. Here’s a teaser of what’s in the full report (click graphic for larger size):
On any given property, these benefits can add up to big money over the long run. The report includes three examples that show the potential cumulative value of a suite of green infrastructure retrofits to the owners and tenants of medium-sized office buildings, midrise apartment buildings and retail centers. In both the office building and apartment building examples, the total present value of benefits approaches $2 million over 40 years; for the retail center, benefits exceed $24 million, including nearly $23 million of increased retail sales for tenants.
The report shows why it’s essential for players in the commercial real estate industry to consider the full range of green infrastructure benefits, in order to make wise investment decisions. This is true both for new construction projects — to take full advantage of opportunities to integrate green design features — and at existing developed sites, where investments in retrofits can improve older properties and create value.
Notably, in some cities, compliance with local stormwater regulations may require the use of green infrastructure practices for new development. In many other places, these same practices, although not required, provide an allowable pathway to compliance. Recognizing the true benefits of green infrastructure can help developers maximize their return on investment when determining how best to comply with — or even exceed — such local rules.
Impacts on national policy
The report’s findings also have important implications for national policy. The U.S. Environmental Protection Agency is long overdue to update its stormwater rules, which, if done right, significantly would expand and accelerate the deployment of green infrastructure nationwide. Today’s report shows that, in addition to achieving cleaner water and healthier communities, federal leadership on this front can help create value in the commercial real estate market.
Ultimately, green infrastructure is a win-win for both the private and public sector. As Howard Neukrug, commissioner of the Philadelphia Water Department, said: “When private property owners construct green infrastructure and manage their on-site stormwater, not only can they benefit financially, they are also helping to transform pockets of our city into Greened Acres. This is public/private partnership in its truest sense.”
