Integrated Infrastructure Edward A. Clerico, P.E. , LEED® AP President, Alliance Environmental LLC March 10, 2010 eclerico@AllianceEnvironmentalLLC.com www.AllianceEnvironmentalLLC.com Integrated Infrastructure • Progression from water/wastewater to water reuse to energy/water (CHP) to water/energy (heat pump cooling/heating) to carbon conversion to biogas • Some aspects are not new and existed in times of scarcity • Some aspects are completely new – technology that allows high performance at small scale Simple Logic • Why do we produce potable water to carry our waste? Copyright Ed Clerico, 2007 • Why do we light and ventilate unoccupied rooms? • Why do we produce energy from scarce resources, and in a manner whereby much is discarded? The key is finding affordable effective systems and practices that fit each specific case Ecology as Infrastructure Carriage Farm educed impervious cover educe water demand 43% rganic land management – integrated st management lter surface water runoff roundwater recharge at preexisting nditions mproved biodiversity ocal food production • 46% lower energy consumption • Ground source heat pump • Natural ventilation • Daylighting • 85% waste landfill diversion • Recycled content and resource reuse • Indoor air quality –low voc, high filtration Integrating Functional Systems Organic Hay Rain Garden Grass Fed Beef Solar Photovoltaic Panels Geothermal Heat Pump Urban Systems Taking advantage of high density characteristics and the benefits of concentrated human activity Tear Drop Park Vegetated Roof River House Linear vs. Integrated Systems Segregated Systems Approach Is Not Sustainable http://www.storyofstuff.com/ Stuff Solid Waste Energy Community Systems Segregation and Fragmentation Creates Inadequate Function 4 quads + 4 quads = 8 quads US (Mark Shannon 2008) Linear Segmented Approach Solid Waste Community Energy (35%) • Contaminates environment on disposal side Stuff Energy • Depletes resources on supply side Energy •Adds energy at each step Functional System Integration Integrated Systems Reduce and Reuse Nonpotable Water Reuse Energy • Release less contaminants to environment on post consumer side Stuff Energy • Use less natural resources on production side Natural Resource Recycling Energy •Add less energy at each step and extract energy post consumer use Solid Waste Energy (80%) Nutrient Recycling General Benefits of Decentralized Systems “Just-In-Time, Just-The-Right-Size” service delivered without excess capital - built to exact customer needs and specifications Innovation oriented – allow change with each project Competitive – allow for competitive systems and service mechanisms High Efficiency – capture benefits of reuse, shorter distances, less energy input, less consumption, less waste Low security risk due to smaller size and greater dispersion Benefits of Decentralized Water Systems Avoid undesirable secondary impacts (i.e. sprawl), yet allow modern planned development concepts Conducive to “Smart Growth” and “Low Impact Development” concepts that incorporate stormwater reuse, groundwater recharge and integrated water resource management Provide higher quality effluent that has nutrients removed – simply because it has to be acceptable for reuse Eliminate infiltration and inflow conditions that are readily addressed in small systems Capture embedded energy that would typically dissipate into the sewers and earth Draft Green Building Standards ASHRAE 189.1 Total building sustainability package • Site Sustainability • Water Use Efficiency • Energy Efficiency • Indoor Environmental Quality • Building impact on Atmosphere, Materials and Resources • Construction and Operations Functionality Date of 1st System Water Reuse Research 1987 95% Toilet flushing Office 1989 95% Toilet flushing School 1990 75% Toilet flushing Commercial Centers 1993 70% Toilet flushing Stadiums 1996 75% Toilet flushing Urban Residential High Rise 2000 50% Toilet flushing, cooling, irrigation and laundry Building Type 30 Systems 20 Years 80% Reuse Nonresidential 50% Reuse Residential Water Uses New England Patriots Stadium Foxboro, Massachusetts • Economic, Environmental and Social Equity • 68,000 Seat Stadium represents beneficial reuse at prime public and institutional sites. • System provides reuse capacity to entire commercial zone within Town of Foxboro.
