What greenroofs improve.
The Chesapeake Bay
Sediment can smother benthic (bottom-dwelling) plants and animals, such as oysters and clams. Suspended sediment clouds the water, preventing light from penetrating to the leaves and stems of underwater grasses, or submerged aquatic vegetation (SAV).
High concentrations of toxic materials also may be present in sediment, which further contaminate waterways. Sediment carries excess nutrients, particularly phosphorus, into Bay waters, compromising water quality. Accumulations of sediment can clog waterways and ports, making traffic difficult or hazardous, and requiring dredging.

recycling harsh roof microclimates into living, breathing places.

ADAPTABILITY, VALUE, ECOLOGY and STABILITY
Greenroofs allow buildings to require and demand less engergy. They make buildings less of an “energy hog”

COUNTY DATA COLLECTIONOnce the roof is established, the portion with the green roof system will be monitored and measured during an extended period and compared to a similar, non-greened portion of the roof. Mike Stumbaugh, Director of General Services will use digital thermometers attached to micro computers (called HOBOs) to measure and record the changes in temperature from inside and out. Coefficients of energy transfer will be used to determine what the roof is doing.
Energy hog?

COUNTY DATA COLLECTIONThis will allow us to understand exactly how much energy is conserved.
County employees are certain to hear a little less rumbling of air handlers and chillers.
County residents should not expect their taxes to plummet as a result of our increased efficiency, but over the life of the roof, it will conserve energy that continues to be more costly.
Similar studies will look at water quantity and
quality after the roof is complete.

Water Quality
Plants and soil medium filter airborne pollutants. The Department of Energy is providing grant funding for greenroofs. Greenroofs filter phosphorous and nitrogen, among others from rainwater.
…and decrease the energy (and therefor, pollution) required to keep us comfortable.

Phospherous and nitrogen are bi-products of current regulations on coal and other fossil fuel powered energy plants. In urban areas, these airborne nutrients do not have an opportunity to be cleaned through the natural cycle as they would in more natural areas.

Water Quantity
On average, across the United States, green roofs are shown to retain 50-70% of water from rainfall events. Peak runoff flows are reduced up to 85%. These peak runoff flows are responsible for the most severe erosion along our rivers and streams. After full saturarion, a greenroof will release rain in excess of one inch, on average.

Costs
Costs for greenroof systems begin under $10
per square foot...
An extensive greenroff, such as the one growing on the County
Office Building is the least expensive. Extensive greenroofs are
not meant to be an active space. They are limited access and are
to serve no greater function than those previously mentioned.
An Intensive greenroof anticipates uses for relaxation and
reflection and involve larger plants, deeper soil medium, and
frequent use.
Generally Extensive roofs range between $5-$15 per square foot
for system alone. As with any product that has more to offer,
intensive green roofs cost out higher, but are still cost-effective.
