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

Innovations in Energy Analysis Innovations in Energy Analysis Using a Second Law Approach to Energy Savings FIRST LAW OF THERMODYNAMICS Law of energy quantity Focus on energy conservation Ignores quality losses SECOND 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

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.

District Energy Sharing System Schematic

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

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. Energy sharing for communities with: 45% residential 30% office 25% retail Can supply 25% to 34% of the total thermal energy Using the Energy Imbalance DISTRICT ENERGY SHARING & WATER RECOVERY

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 Reducing Energy Consumption DISTRICT ENERGY SHARING & WATER RECOVERY

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