  1. Renewable Energy Generation Achieve net-zero facilities and GHG reduction goals by: • Geothermal Energy Systems • Photovoltaic Systems • Biomass Systems • Landfill Gas Microturbines • Wind Turbines • Solar Water Heaters • Concentrated Solar Power • Methane Recovery Systems

  2. Renewable Energy –Pain or Gain? Transmission loss is #1 source of energy inefficiency Tremendous opportunities exist for increased energy efficiency when generation and use are well matched Power failures (blackouts, brownouts) create inefficiency and undermine mission Trigeneration and other efficiency/ renewable power solutions can address these and other issues with demonstrable ROI

  3. Innovations in Energy AnalysisUsing a Second Law Approach to Energy SavingsFIRST LAW OF THERMODYNAMICS•Law of energy quantity•Focus on energy conservation•Ignores quality lossesSECOND LAW OF THERMODYNAMICS•Law of energy quality•Focus on energy quality loss as opportunity for energy savings•We use MCDA to account for stakeholder priorities/preferences THE SCIENCE OF DECISION MAKING •Methodical analysis•Supports the development of planning and programming requirements

  4. Net Zero Installation Proposed Definition A net zero installation is one which applies an integrated approach to management of energy, water, and waste to capture and commercialize the resource value and/or enhance the ecological productivity of land, water, and air. Its key attributes are: • A fundamental shift towards cyclical handling of resources, virtually eliminating the concept of waste. • Ecologically derived design method to systematically support resource recovery by synergistically combining outputs and inputs. • Operates through breaking down “stovepipes” of assessment and design decision-making rather than following traditional approaches based on single technical discipline problem solving. • Focus on capturing value, not minimizing initial cost, through effective inter-disciplinary project teams. Net Zero Installation Concept

  6. District Energy Sharing System Schematic

  7. DISTRICT ENERGY SHARING & WATER RECOVERY • Modern Building Challenge Modern buildings attempt to balance their own heating and cooling demands to reduce the energy required to heat and cool the building.

  8. DISTRICT ENERGY SHARING & WATER RECOVERY • Using the Energy Imbalance • Energy sharing for communities with: • 45% residential • 30% office • 25% retail • Can supply 25% to 34% of the total thermal energy District Energy and Water Sharing balances the heating and cooling demands of an entire community to reduce the energy and water required to meet the needs of the community.

  9. DISTRICT ENERGY SHARING & WATER RECOVERY • Reducing Energy Consumption Heat recovery and alternative high or low grade thermal energy sources are used to store or provide the net energy demand. 50% of peak heating/cooling provides 90% of annual energy 60% of a building's energy consumption is heating & cooling

  10. DISTRICT ENERGY SHARING & WATER RECOVERY • Enabling Alternative Energy Reduction in energy demand maximizes feasibility of other alternative energy sources
