4 Outline/Agenda 1. Trends in Hospitality 2. Opportunities in the Hospitality Industry for Geothermal 3. The Charmant Hotel La Crosse WI 4. Focus on Energy Verification of Delivered Results of the Geothermal System 4

5 Hotel Industry in US 5 Billion Square Feet in US $7.5 Billion Energy Bill / Yr 47,000 Hotels Energy Accounts for 6% of Operating Costs 5

6 Trends in Hotel Operation LEED v4 - Standards for Hotel Ratings LED Lights - Grown in Use 300% in 4 Years Clean Simple Elegant Spaces Drive Hotel Design Increasing Hybrid Use Hotel/Theatre Hotel / Gallery Mobile Meeting and Officing Facilities More of Guest Experience on Guest s Smartphone Balancing Generational Concerns: Millennials vs Boomer Needs Systematic Savings Room Key Cards, Hotel Management Systems Destination Experience, Unique Spaces 6

7 Drivers Toward Sustainability Cost savings. Bottom line financial return from implementation of sustainable business practices is strongest motivating factor Fiscal and economic incentives Regulatory affairs Stabilized utility prices and availability 7

8 Fiscal and Economic Incentives Tax credits (Historic, Energy) Waiver of development fees Cash incentives for achieving certification Public investment in new or improved infrastructure Grants to cover the soft costs associated with green design Low interest loans Expedited plan review by building departments Permissions for additional density 8

26 Conclusion Geothermal: A Proven Technology for Hospitality All electric solution that can be powered by source or site energy. Renewable energy component extracting solar energy stored in the earth. High efficiency system due to the earth s relatively constant temperatures as a source or sink for heat energy. Versatile as a retrofit system with compact distributed systems and central plant configurations. Can be integrated with other renewable systems (Solar DHW) Backbone for heat energy recovery for building or campus HVAC systems Long system life and low cost maintenance requirements; significantly reducing life cycle cost Some of the lowest demand profiles of any HVAC system 26
