1 FLORIDA SOLAR ENERGY CENTER A Research Institute of the University of Central Florida

2 Context Florida s energy purchases result in large quantities of money (and economic activity) leaving the State, much to foreign entities. For the first time, the evidence indicates that the global demand for petroleum is beginning to exceed the world s ability to produce it. As a result, energy research and development are becoming more and more critical to both Florida and the nation.

3 Into the Storm

4 Why Buildings?

5 Buildings Dominate 2004 Actual Electric Use by Sector (233 TWh)

6 FSEC Buildings Research High-performance buildings research Radiant barriers and cool roofs Duct leakage and uncontrolled air flow Building moisture control and diagnosis High-performance windows and daylighting High-performance air conditioners and controls Sealed-attic technologies Most have been implemented in Florida s building energy codes and standards, saving more than $100 million annually in energy cost.

7 The Art of the Possible The Lakeland House Project

8 Are Windows Important? Control House ZEH

9 What About Roofs? Control House ZEH

10 Efficiency First

11 Hottest Day Ever!!

12 Net Energy Use

13 Relocatable Classrooms 36% of the nation s schools use relocatable classrooms Relocatables are often energy hogs Suspected source of health problems Perceived as low quality learning environment Constructed to the minimum standards Growth in public school enrollment continues

14 Objectives Substantially improve energy performance of prototype designs in various climates Incorporated daylighting designs to improve classroom learning atmosphere Measure side-by-side energy performance Standard classroom model Energy-efficient classroom prototype Substantial difficulty obtaining participating partners.

15 Energy Savings Potential

16 Measured Performance

17 FLORIDA SOLAR ENERGY CENTER A Research Institute of the University of Central Florida Building America Industrialized Housing Partnership: Building High Performance Housing

18 High Performance Housing 30% - 70% energy savings from efficiency and renewables Excellent Comfort Outstanding Indoor Air Quality Durable and Low maintenance Disaster Resistant (Strong and Leak free) Resource Efficient ( Green ) Marketable

19 BAIHP Overview One of five prime contractors to US DOE Building America program Initiated in September, 1999 Team comprises FSEC (lead), UCFIE, WSU, ALACF, Fl-Hero, Calcs-Plus + over 50 builders, home manufacturers and suppliers BAIHP works in all housing sectors, focusing on factory built housing.

20 Up to 70% Savings (Cooling Energy / 1,000 sf) vs Delta T Cooling Energy (kwh/day/1,000sf) Frame House May 01 to Sep 30, 2002 y = 1.466x R 2 = Lakeland Control House May 01 to Jul 19, 2002 y = x R2 = Hoak Residence May 01 to Sep 30, 2002 y = x R 2 = Lakeland PVRes House May 01 to Sep 30, 2002 y = 0.393x R 2 = Avg Daily Delta T (F) (Outdoor - avg. Indoor)

21 NC A&T State University Greensboro, N.C. Side-by-side 1528 ft 2 homes Simulated occupancy Project Leads- Turner, McGinley NCATSU; Beal, Moyer, Parker - FSEC

22 NC A&T State University Heating Season Research Results Nov Feb % average heating energy savings 70% peak heating energy savings

23 The HFH Partnership FSEC Supports HFH s Environmental Initiative Energy Education/Training: State, Regional, and National Seminars/Conferences Habitat Green Team Leader Technical Assistance Blitz Builds Standard Construction 50+ affiliates in 20 States to build 500+ Energy Star now HFH Best Practice

24 BAIHP Partnerships Saving more than $12,000,000/yr in 85,700+ homes!

25 FSEC Building America Team

26 Codes & Standards Technical support for Florida s Energy Code Service on Technical Advisory Committees Produce and maintain Florida s performancebased code compliance software (EnergyGauge Technologies: Radiant barriers, duct leakage, cool roofs, moisture control, fenestration Active participation in IECC code process: Major inputs on performance compliance Florida meets or exceeds national codes Florida consistently receives A-grades

27 Home Energy Ratings Complements Florida s building Codes and Standards Florida law: Building Energy Efficiency Ratings Act of 1994 FSEC acts as RESNET accredited HERS Provider for State of Florida FSEC developed and maintains RESNET accredited software (EnergyGauge USA)

28 EnergyGauge USA

29 What is EnergyGauge Easy-to-use, powerful hourly simulation design tool specifically for: The design of energy-efficient homes and The evaluation of utility peak demand impacts Featuring: FSEC-enhanced DOE-2.1E hourly simulations IECC Code compliance analysis Accredited HERS Rating analysis Accredited federal tax credit qualification software

30 FSEC Enhancements More accurate computation of heating and cooling system part load performance More accurate prediction of indoor air relative humidity Coil airflow and system sizing impact on heat pump and air conditioner performance More accurate ground contact modeling More accurate attic modeling (including attic ventilation, reflective roofing and radiant barriers) Detailed hourly modeling of duct heat transfer and air leakage

31 The 25 TWh Example 160,000 new Florida homes per year 24,000 tax credit homes per year 24,000 solar water heaters per year 6.2 million existing Florida homes (achieve 15% savings) 62,000 home improvements 62,000 solar water heaters per year Photovoltaic Systems 9,000 PV systems per year (2 kw peak)

32 Off-the-Shelf Technology 42% annual energy savings (~$630) 2.06 kw 2000 sq.ft., 3 BR, single story, concrete block home

33 Florida Benefits Avoided capacity New jobs Tradable renewable energy credits (TRECs) CO 2 savings Cumulative Ten Year Totals Total energy savings Total consumer cost savings Total fuel not purchased Avoided generation costs 24.7 TWh $2.47 billion $1.24 billion 1,669 MW $1.67 billion 126,000 $420 million 26.4 million tons

34 A Very Different Result Old Pie New Pie
