5 Hydrologic Cycle The distinction between indoor water use and stormwater runoff issues is artificial. Source: Delaware River Basin Commission

6 Water Mass Balance in High-Rise Building Rainwater 1,340 Municipal water 33,650 Humidity 300. Reused: 19,150 Evaporation from cooling tower 8,140 Sewage 23,230 Stormwater to river 490 Irrigation 40 Evapotranspiration from roof 860 Other losses 2,540 Krogmann et al. (2007)(2007) Unit: gallons per day

7 Water Mass Balance in High-Rise Building Reuse Scenario. Unit: gallons per day Krogmann et al. (2007)(.)

8 Water Management Goals Protect natural areas that absorb water Reduce non-point source pollution Recharge groundwater Conserve water inside and outside the building Take advantage of opportunities to incorporate green stormwater management and energy efficiency measures Flooding along NJ roadways

9 Water + Energy Benefits Green Roofs \ Image credit: Queens Botanical Garden Absorb, slow, and filter stormwater Remove heat through evapotranspiration, reducing temperatures of the roof surface and the surrounding air Act as insulators for buildings and reduce energy needed for heating and cooling

10 Water + Energy Benefits Permeable Paving Systems greenbuilding.rutgers.edu Combining different types of permeable pavers provides the opportunity to meet a variety of accessibility needs while achieving onsite water management. Image credit: Queens Botanical Garden Light colored permeable pavers help mitigate the urban heat island effect.

11 Water + Energy Benefits Street Trees & Urban Forestry greenbuilding.rutgers.edu Careful selection and placement of shrubs trees. provides shade reduces solar heat gain in summer prevents heat loss in winter provides windbreaks reduces and slows stormwater runoff Image credit: NYC DEC

12 Overcoming Regulatory Barriers greenbuilding.rutgers.edu Regulations can inadvertently create barriers to implementing best practices. Reviewing and revising zoning and planning regulations can promote energy efficiency and water management best practices by eliminating these barriers.. For example, in Jersey City, changes to zoning promoted the installation of green roofs through exempting green roofs from the rooftop area limit of 20% of rooftop appurtenances Source: Jersey City Ordinance

13 Nested Scales Building Site Neighborhood Watershed

14 Impacts Beyond Site Boundaries Managing water where it falls reduces the amount of stormwater that runs into local waterways reduces burden on wastewater treatment plants, thus saves money through avoided cost reduces energy used by wastewater treatment plants Image credit: Daniel Case Passaic River

15 Scale Economies in Wastewater Treatment Scale economies in wastewater treatment exist Average Annual Comparison, Including Capital, Operations, and Infrastructure Costs, Meta Data Cheapest technologies are: advanced secondary treatment and basic secondary treatment. However, some technologies show continuing scale economies under high density conditions but not under low density conditions (e.g. tertiary treatment). Cost, $ per m 3 per day Capacity, m 3 per day x 10 3 Primary Only-High Density Primary Only-Low Density Wetlands-High Density Wetlands-Low Density Basic Secondary WWTP- High Density Basic Secondary WWTP- Low Density Advanced Secondary WWTP-High Density Advanced Secondary WWTP-Low Density Tertiary WWTP-High Density Tertiary WWTP-Low Density Pond Treatment-High Density Pond Treatment-Low Density Tank Treatment-High Density Tank Treatment-Low Density

16 Policy Examples Philadelphia Green City, Clean Waters greenbuilding.rutgers.edu Philadelphia's 25-year plan to protect and enhance our watersheds by managing stormwater with innovative green infrastructure. Vision includes elements such as: Large-scale Implementation of Green Stormwater Infrastructure Requirements and Incentives for Green Stormwater Infrastructure Program includes elements such as: Green Stormwater Infrastructure Map Green Stormwater Infrastructure Tools Performance goal = achievement of a Greened Acre Each Greened Acre represents an acre of impervious cover within the combined sewer service that has at least the first inch of runoff managed.

18 Policy Examples NYC Green Infrastructure Plan greenbuilding.rutgers.edu Goal Framework for cleaning waterways by building innovative, cost-effective green infrastructure to manage one inch of stormwater runoff from 10% of the impervious surfaces in the combined sewer areas of the City by 2030 Source: NYC Green Infrastructure Plan Accomplishments Green Infrastructure Design Standards Neighborhood Demonstration Area Projects Monitoring and Modeling Green Infrastructure Grant Program Case Studies Source: NYC Green Infrastructure 2012 Annual Report

19 Policy Examples planyc Green Buildings & Energy Efficiency NYC Green Building Policy Public and private sector approach to address the 1 million buildings of NYC NYC s Green Codes Task Force reviewed NYC s codes and regulations, making recommendations on topics from site design to resilience to climate change Deep energy retrofit pilots in City projects (6.5% of the building square footage owned and operated by the City) Comprehensive tracking of greening of NYC s buildings NYC Energy Efficiency Policy NYC has launched three major sets of energy efficiency policies over the past several years, one of which impacts all buildings, one that focuses on cuts in key sectors such as municipal and institutional, and one that concentrates on large, existing buildings - Greener, Greater Buildings Plan (GGBP). GGBP consists of four regulatory elements: Benchmarking, NYC Energy Conservation Code, Energy Audits & Retro-commissioning, Lighting & Sub-metering. Source: planyc

20 Policy Examples - Camden SMART Initiative Comprehensive network of green infrastructure programs and projects for the City of Camden. Collaborative effort: City of Camden, Camden County Municipal Utilities Authority, Cooper s Ferry Partnership, Rutgers Cooperative Extension Water Resources Program, NJ Tree Foundation, NJ DEP, community organizations, and residents In the first year, the Camden SMART Initiative resulted in demonstration projects designed to capture, treat, and infiltrate over 800,000 gallons of stormwater annually.

23 Recommendations View water management from the framework of the hydrologic cycle Consider the relationship between scale and strategy Review regulations for unintended barriers to implementing green infrastructure Greater linkage is needed between green building and green infrastructure projects and programs Image Credit: Queens Botanical Garden A rain water harvest system on this outdoor terrace collects water to use in a landscape feature, thus conserving water, reducing stormwater runoff, and celebrating water as a valuable resource.
