2 AIA CEU s TLC Engineering for Architecture is a Registered Provider with The American Institute of Architects Continuing Education Systems. Credit earned on completion of this program will be reported to CES Records for AIA members. Certificates of Completion for non-aia members are available on request. This program is registered with the AIA/CES for continuing professional education. As such, it does not include the content that may be deemed or construed to be an approval or endorsement by the AIA of any material of construction or any method or manner of handling, using, distributing, or dealing in any material or product.

3 AIA Learning Objectives Understanding the challenges regarding progressive sustainable designs, both through cost and efficiency. Leveraging challenges into opportunities to design infrastructure for progressive technologies, including Net-Zero Building. Realizing the importance of participation in early design decisions. Understanding the challenges of carbon neutrality from an institutional perspective.

4 What Is Sustainability? Sustainability is avoidance of the depletion of natural resources in order to maintain an ecological balance. Power Plants are fueled by resources that will some day run-out.

5 What is a Net-Zero Design? A Net-Zero Design is a building with zero net energy consumption, meaning the total amount of energy used by the building on an annual basis is roughly equal to the amount of renewable energy created on the site. Amid growing concerns about rising energy prices, energy independence, and the impact of climate change, statistics show buildings to be the primary energy Consumer in the U.S.

15 UCF Challenges to Energy Master Planning Utilities are not a high priority unfunded infrastructure How do we forecast commodity pricing volatility? Pressure(s) from constrained budgets Fixed PO&M PSC Filing # Rate forecast and impact to forward price curves

16 UCF Challenges to Energy Master Planning Resistance to change: Utilities are not the university s core business Adversary vs. Partner Campus distributed energy systems & micro-grids- perceived as threats? Commodity capacities and tipping points Match diversified load projections to the Utility Campus Master Plan GHG trajectory as a result of additional utility demands from load growth Deploying a renewable and reliable energy future Regulated Market Impacts

19 PV PPAs In a Regulated Environment UCF participation through a PPA is prohibited under the Florida Public Service Commission Decision: Docket EU; Order (1987). This order does not allow a third-party ownership PPA model. Sticking point to allow a PPA is contained within the Florida Statute and its definition of Public Utility. The statute in part reads; (1) Public utility means every person, corporation, partnership, association, or other legal entity and their lessees, trustees, or receivers supplying electricity or gas (natural, manufactured, or similar gaseous substance) to or for the public within this state. The term highlighted to or for the public, has been construed to potentially mean delivery to a single customer. Interpreting this definition as described, would label UCF as the only customer and the lessor as a public utility since the output of the project would be dedicated to one customer.

33 Dealing with Obstacles to Eventually Achieve Net-Zero Designs Not All Buildings Are Good Candidates for Net-Zero Planning For Future: Technology Improvements

34 Grants / Bonding As Revenue Producing Technology Renewable Energy Can be Bonded Look for local / state / federal grants to help subsidize the funding.

35 Conclusion Net Zero seems challenging but planning can allow for positive changes in the future
