The long-term investment return of metal roofing over the quick to be replaced asphalt roof … The mean difference between the cost of the green roof and the conventional roof is defined as the cost gap. But for long-term property owners, green roofs can make financial sense depending on project conditions and local stormwater policy and green roof incentives. Known as living roofs, eco-roofs, and vegetated roofs, green roofs offer many benefits to the user. Then we imagined what the city could be like if all of its roof space was green. Solar panels for local energy. (DMI) as part of its Marketplace of Ideas series. //www.flowscapes.org. The extensive ones, which simply use a layer of hardy groundcovers like sedum, are a lot cheaper (about $10/square foot) than intensive green roofs, Local policy incentives to install green roofs, such as stormwater fee reductions, tax abatements, and direct financial incentives, can also render installation of a green roof financially attractive. Example green roof lifecycle cost-benefit analysis calculations can be found in: Depending on the approach to the lifecycle cost analysis and project specifics, some of the above found green roofs to have the lowest lifecycle costs, while others found the traditional roof to have the lowest lifecycle costs, and still others found them to have comparable lifecycle costs. 2008. In Alberta, a green roof can cost between $10–40/square foot, compared to the cost of installing traditional residential waterproof roofing membrane ($6/square foot). Nearly 2/3 of those savings would come from reduced energy use; the other David Evans and Associates, Inc. and ECONorthwest. roof, can expect to spend betwee… These costs are consistent with costs noted in the literature (e.g. savings come from improved stormwater management and public health benefits of absorbing nitrogen oxides (NOx).

The cost Furthermore, those “white” roofs do nothing to help mitigate the storm water run-off, which should be a priority of NYC with their antiquated Because green roofs extend the lifetime of a roof between 200 and 300 percent, owners are able to save significant costs in the long run. Green roofs last longer than conventional rooftops because the membrane is protected from UV radiation and heat stress. Although installation of a green roof usually involves higher upfront costs than a traditional roof, there are many economic benefits that can make up for this. A truss might be the only feasible solution in a wide building that does not have a structural ridge beam, as the collar ties of a conventional roof would require mid-span support. If you opt for a less-costly system such as corrugated or ribbed metal panels, your cost will likely fall within $5.50 to $7.50 per square foot or $550 to $750 per square installed, depending on the metal thickness (gauges for steel or mils for aluminum) and the quality of paint finish (polyester or acrylic vs… At a net-zero home in San Francisco, the house's green roof is more of a brown roof… The most common way to evaluate lifecycle costs and benefits of a green roof is to compare all the costs and benefits of the green roof over the duration of the study period to all the costs and benefits of an alternative roof type(s), typically a comparable dark and/or reflective roofing membrane. It is excellent for determining whether higher initial costs are justified by reducing such future costs as operating, maintenance, repair or replacement costs and/or producing additional benefits, such as energy savings.”. This has been the largest driving factor behind the green roof phenomenon in Germany and the United States.”. reasons: 1) Reduce Urban Heat Island: While this may be manageable in the shorter-term, continual climate change will make UHI mitigation vital to tempering potentially-fatal heat waves during the summer months. Chicago already has more than 600 “green roofs,” It’s difficult to respond to such a broad question as to whether or not green roofs are worth it, but from my experience in Chicago, urban green roofs seem to have been very worth their salt for the following The reduction of stormwater volume by green roofs … A green roof pays for itself with its stormwater-management and insulation value. They give off a traditional feel to a home. included in the Green Roof legislation, use of solar thermal systems on NYC multi-family building roof tops would generate greater reduction in of fossil fuel usage (therefore greater reduction in greenhouse If that is the case, two traditional roofs would need to be installed to equal the lifespan of one green roof. green roofs are approximately $6 to $8 per square foot cheaper to install than semi-intensive green roofs, and in both cases larger green roofs cost less per square foot to install than smaller green roofs. (2010) compared the return on investment (ROI) of green roofs in 5 municipal regulatory environments and concluded “Local policy initiatives, however, can create direct incentives that result in positive ROI, and in some cases, first cost savings … Those cities that offer attractive polices for green roofs are often doing so in order to reduce the massive outlays that will be associated with infrastructure upgrades required to comply with the NPDES Part II (Clean Water Act) requirements. Stormwater that runs off a green roof is cleaner than runoff from a conventional roof.

Increased R–value(a measure of the resistance of a material to heat flow) of the roofing system, along with reduced temperatures on the roof lessen HVAC loads, resulting in energy cost savings. Design Guidelines for Green Roofs. Currently I am growing various herbs, carrots watermelons, pumpkins, and corn. That is a sub-variation of hip style, but is actually unusual. Other relevant financial investment information includes, for example, inflation rate, and applicable discount rate.
