Term
What is the intent of the Rainwater MGMT credit?
Definition
Reduce runoff and improve water quality by replicating natural hydrology and water balance of site based on historical conditions
Term
What are the requirements of the Rainwater MGMT credit?
Definition
1.)Percentile of Rainfall Events
2.)Natural land cover
Term
What are the different paths used in the Percentile of Rainfall Events requirement under the Rainwater MGMT credit?
Definition
Path 1.) 95th percentile (3pts, 2HC)
-manage on site the runoff from developed site for 95th percentile of regional or local rainfall events using low impact development and green infrastructure
Path 2.) 98th percentile (3pts, 2HC)
Path 3.)zero lot line projects only
-urban areas minimum density 1.5 far
-manage runoff from developed site for 85th percentile of regional or local rainfall
Term
What is the intent of the Heat Island Reduction credit?
Definition
minimize effects on microclimate and human and wildlife habitats by reducing heat islands
Term
What are the 2 requirement options for the Heat Island Effect?
Definition
1.)Nonroof and roof (2pts, 1 HC)
-combo of:
-nonroof: plants, shade structures with high SRI, vegetated structures, high SRI paving materials, open grid paving
-high reflectance roof: SRI for a low sloped roof must be an 82 or 64 after 3 years. Steep slope must be a 39 or 32 after 3 years
-vegetated roof
Option 2.) Parking under cover
-minimum 75% parking under cover
-any roof used must have 3 yr SRI of 32, use materials w/ initial SRI of 39
-be vegetated
-or be covered with RE generation systems
Term
Heat island
Definition
difference in thermal gradient between developed areas
Term
Heat island effect
Definition
absorption of heat by hardscapes such as dark, non-reflective pavement and buildings
Term
Albedo/Reflectance
Definition
ability of a surface to reflect sunlight on a scale of 0-1 with 0 being the least reflective and 1 being the most
Term
Emissivity
Definition
ratio of radiation emitted by a surface to radiation of a blackbody at same temperature
-measured on a scale of 0-1 with 0 being the most reflective and 1 being the blackbody
Term
Emittance
Definition
ability of a surface to shed thermal radiation on a scale of 0-1 with 0 being the least and 1 being perfect emitter
Term
Solar Reflectance Index (SRI)
Definition
Ability of a surface to reject solar heat on a scale of 0-100. Higher the rating, the better it is at rejecting solar heat. It is a combo of reflectance and emittance
Term
