How Greenroofs Save Money
Greenroofs are more than just environmentally sustainable – they’re also financially sustainable. Beyond their aesthetic appeal and environmental contributions, they’re financially savvy investments that can yield significant savings over time.
Energy Efficiency and Cost Savings of Greenroofs
Reduced Cooling Costs
One of the most immediate and impactful ways greenroofs save money is through reduced energy costs. Traditional roofing materials like asphalt and concrete absorb a substantial amount of heat, increasing the need for air conditioning in the summer. Greenroofs, however, provide natural insulation and cooling. The plants and soil absorb and retain heat during the day and slowly release it, reducing the indoor temperature. The insulating effect of green roofs also works in winter, reducing heating costs by preventing heat loss.
Increased Energy Efficiency
Beyond direct cooling and heating savings, greenroofs contribute to overall energy efficiency. By maintaining more stable indoor temperatures, they reduce the strain on HVAC systems, leading to lower maintenance costs and extending the lifespan of these systems.
Extended Roof Lifespan
Protection from the Elements
Greenroofs protect the underlying roof materials from extreme weather conditions, UV radiation, and mechanical damage. This can noticeably extend the lifespan of a roof. The average traditional roof needs replacement every 20 years or so, but a well-maintained greenroof can last 40 years or more. This extended lifespan makes for long-term cost savings on roof replacements.
Reduced Thermal Fluctuations
The plants and soil on a greenroof buffer the roof from temperature extremes, reducing thermal expansion and contraction cycles that can degrade roofing materials over time. This stabilizing effect minimizes wear and tear, further extending the roof's life and reducing maintenance costs.
Stormwater Management
Reduced Drainage Costs
Greenroofs absorb and retain rainwater, significantly reducing the volume of runoff. This mitigates the burden on urban drainage systems, decreasing the need for expensive stormwater infrastructure. Many cities impose fees based on the amount of stormwater runoff generated by a property, and greenroofs can help reduce these fees by managing water onsite.
Flood Prevention and Water Quality Improvement
By retaining and slowly releasing rainwater, greenroofs can help prevent flooding and decrease the risk of water damage to buildings and infrastructure. Additionally, they filter pollutants from rainwater, improving the quality of water entering the drainage system and reducing the cost of water treatment.
Increased Property Value and Marketability
Aesthetic Appeal
Greenroofs enhance the beauty of a building, making it more attractive for potential buyers or tenants. A building with a greenroof stands out and offers a unique selling point.
Positive Messaging
With growing awareness of environmental issues, green buildings are increasingly in demand. A greenroof signals a commitment to sustainability, attracting environmentally conscious buyers and tenants.
Incentives and Grants
Government Incentives
Many local governments offer financial incentives, grants, and tax rebates to encourage the installation of greenroofs. These programs can significantly offset the initial installation costs, making greenroofs a more affordable option.
Cost-Sharing Programs
Some municipalities have cost-sharing programs that cover some of the expense of the installation and maintenance of greenroofs. These initiatives recognize the broader community benefits of greenroofs, such as reduced urban heat islands and improved stormwater management.
Greenroofs are more than just an eco-friendly trend – they’re an important investment, both environmentally and financially. By reducing energy costs, increasing property value, benefitting buildings’ structural integrity, and more, greenroofs can help you save in the long haul.
