Achieve net-zero facilities and GHG reduction goals by:
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 AnalysisUsing 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
