- 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

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

- 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 Net Zero

- District Energy Sharing System Schematic
- Slide 14
- 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
- Slide 15
- 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
- Slide 16
- 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
