1 Southeastern Facility Masters Conference Southeastern Association of School Business Officials November 18-20, 2008 Little Rock, Arkansas Larry Schoff, PE Consultant to the US Department of Energy’s EnergySmart Schools Program Shades of Green Viewing High Performance (HP) Design

2 2 1. Promote 50% improved efficiency in new schools and major renovations or additions and 30% in existing buildings 2. Develop and disseminate technical guidance, best practices and case studies which address existing buildings and new construction 3. Identify sources of financing for high performance schools and provide tools that help stakeholders make a compelling business case 4. Collaborate with national, regional, and local partners to promote healthy, high- performance schools Anticipated total energy savings from 700 schools: quads with $14 million in cost savings to schools by 2020 Catalyze significant improvements in energy efficiency by promoting schools that progress towards net-zero energy buildings DOE EnergySmart Schools GoalsApproachImpact

3 3 DOE EnergySmart Schools (cont.) New Construction and Major Renovations Primarily suburban districts and states with growing populations Opportunity: Design in sustainability and high-performance from the outset Target: At least 50% energy savings over ASHRAE standards Existing Buildings/Retrofits Primarily urban and rural districts, some driven by consolidations or need to upgrade aging infrastructures Target: At least 30% energy savings

4 4 Presentation Outline Defining High Performance/Green/Sustainability High Performance Design Guides “Shades of Green” – Areas and Elements of High Performance Design “Shading” Your High Performance Design Examples of “Shades of Green” Schools Financing High Performance Schools Conclusion

5 5 Defining High Performance/Green/ Sustainability Sustainability Development that meets the needs of the present without compromising the ability of future generations to meet their own needs Green To significantly reduce or eliminate the negative impact of buildings on the environment and on the building occupants High Performance When a building, its systems and the occupants are operating effectively and efficiently

6 6 Defining High Performance/Green/ Sustainability (cont.) HP/Green Design Concepts apply to all building types LEED-NC initially applied to all Now – Building types having LEED documents –K-12 Schools –Shell Buildings –Campus CHPS – Now adopted by several states

7 7 Defining High Performance/Green/ Sustainability (cont.) Life Cycle Cost vs. First Cost All of the decisions affecting this entire life cycle cost are made in the smallest portion of the building life cycle cost-design. High performance design must be incorporated from the start! Operation 50% Construction 11% Financing 14% Alterations 25% Design is ONLY 6%-8% construction cost

8 8 Defining High Performance/Green/ Sustainability (cont.) Integrated or Whole Building Design Whole-building design considers all building components Integrates all the subsystems Design team should be fully integrated from the beginning; all the pieces must fit together –Building design team can include architects, engineers, building occupants and owners, and specialists in areas such as indoor air quality, materials, and energy use.

45 45 Principles of Financing Making a Business Case Financing Options State, Federal and Non-Profit Resources Co-branded by ASBO Endorsed by NSBA

46 46 Principles of Financing High-Performance Schools Principle 1. Determine Project Objectives Principle 2. Avoid Cream Skimming Principle 3. Identify All Cash Flows Principle 4. Focus on Life-Cycle Cost Analysis Principle 5. Select an Effective Cost-Benefit Mechanism Principle 6. Monitor and Verify Results

47 47 Principle 2. Avoid Cream Skimming Principles of Financing High-Performance Schools (cont.) Investing in relatively low-cost projects with quick paybacks undermines efforts to finance more capital-intensive efforts with significant long-term benefits that can leverage those short-term payback.

48 48 In today’s world, operation of educational buildings should reflect not only the needs of the district but also the needs and goals of the Nation. Let’s make High-Performance Buildings leading to Net Zero Energy Schools one of our goals in the 21 st century. It’s Not Rocket Science Conclusion

49 49 Does a HP Building = Energy Efficient Building? Buildings don’t operate themselves, people do Energy awareness and proper operations are the keys to success in energy efficient operation NO!
