1 Nathan Lammers – Waibel Evan Nutt – Waibel Mike Kennedy - Heapy

2  Introductions – Sustainability / Energy  Building Overview  Technologies  Tour  Energy Conversion Calculation

3  Nathan Lammers ◦ Waibel Energy Systems ◦ Client & Energy Services  Evan Nutt ◦ Waibel Energy Systems ◦ Trane HVAC Equipment  Mike Kennedy ◦ Heapy Engineering ◦ Design and Energy Modeling

4  216,500 ft 2  Technologies ◦ Solar PV ◦ Solar Thermal ◦ Wind Turbine ◦ Rain Water Harvesting ◦ High Efficiency HVAC with Ice Storage ◦ Solar Shades ◦ Metering  Distinctions ◦ US Department of Education Green Ribbon ◦ USGBC LEED Gold ◦ Featured in 2 National Magazines

5

6  Benefits ◦ Renewable, Feeds Domestic Hot Water  Process ◦ Sun Rays, Cold Water In – (HX) – Hot Water Tank ◦ Two Water Loops – 1 Glycol, 1 Preheat for DHW  Total Impact ◦ Reduces fossil fuel heating (non-renewable)

7  Background ◦ Types of Water  Rain – Storm – Grey – Black - Non-Potable - Potable

8

9  LEED Credit  Benefits – ◦ Reduce Transport of DCW– Great Miami Aquifer ◦ Reduce Rainwater Pollution ◦ Reduce Potable Water for Flushing and Returned Wastewater  Filtration reduces the amount of sediment and other pollutants.  Process/Distribution  Synergistic Effect/Total Impact

10  Onsite Collection ◦ – 75kgal Reservoir

14  Kinetic Energy in Wind  Electrical Energy

15  Available Kinetic Energy = ½ mV 2  Available Kinetic Power = ½ pAV 3 ◦ p = Density = 1.23 kg/m 3 ◦ A = Area Swept by blades  Radius of blade = 4.25 m ◦ V = 11 m/s  Calculate Kinetic Power of Wind Turbine  46,449 Watts

16  Find Actual Output of Wind Turbine at 11 m/s  (Approximate) 12,324 W

17  Calculate Efficiency of Power Conversion of Wind Turbine  Eff = 12,324 / 46,449  Eff = 26.5%
