Disasters And Energy Security Management, Florida Solar Energy Center, William Young
FSEC Energy Research Center®
In the past, natural disasters, such as hurricanes, floods, tornados, and earthquakes, were one of our major concern. Now, terrorist events are becoming more common and more destructive. Whether, natural or man made, a disaster can happen at any time, often with little or no advance warning. A disaster can leave many people without adequate medical services, potable water, electrical service and communications for long periods of time. They can be as destructive as Hurricane Mitch leaving several hundred-thousand people homeless or as minor as an afternoon thunderstorm knocking down local power lines to your home. Not only can lives …
Complying With Florida's Green Land Development Standard: Case Studies And Lessons Learned, Florida Solar Energy Center, Robin Vieira
Complying With Florida's Green Land Development Standard: Case Studies And Lessons Learned, Florida Solar Energy Center, Robin Vieira
FSEC Energy Research Center®
The Florida Green Building Coalition, Inc. (FGBC), developed a standard for green land development. It is the first voluntary, non-government standard of its kind to target an entire state. Other groups have created development standards that apply to just a local Home Building Associations (HBA) or a local jurisdiction. The U.S. Green Building Council (USGBC) is beginning a Leadership in Energy & Environmental Design (LEEDTM) for neighborhoods. To comply with Florida's standard, a developer has to earn sufficient points among six categories:
- Protect Ecosystems and Conserve Natural Resources: for example, surveys, conservation areas, wildlife corridors, wetland preservation and management
- Circulation: …
The Benefits Of Using Window Shades, Florida Solar Energy Center, Ross Mccluney
The Benefits Of Using Window Shades, Florida Solar Energy Center, Ross Mccluney
FSEC Energy Research Center®
Windows play an important aesthetic role in our daily lives. At the same time, windows typically add significantly to the cost of heating and cooling buildings. After reviewing the physical principles by which windows add heat to buildings and the standard techniques employed to reduce unwanted heating, this paper focuses on one type of device which is readily available, inexpensive to purchase and operate, and capable of being adjusted to changing conditions on even an hourly basis. The device is the common window shade. This paper develops a simple, but realistic, model for computing the advantage of using reflective interior …

Study Guide For Photovoltaic System Installers And Sample Examination Questions, Florida Solar Energy Center, James Dunlop
FSEC Energy Research Center®
This Study Guide presents some of the basic cognitive material that individuals who install and maintain photovoltaic (PV) power systems should know and understand. This information is intended primarily as a Study Guide to help individuals better prepare for the NABCEP PV installer examination but does not provide all of the materials needed for completing the certification examination. Knowledge of the information presented, knowledge of pertinent sections of the National Electrical Code and appropriate experience and qualifications, are generally required of those applying for and completing the NABCEP certification process. Applicants and certificants are also reminded that local installation codes …

Achieving Airtight Ducts In Manufactured Housing, Florida Solar Energy Center, Janet Mcilvaine
FSEC Energy Research Center®
Data and findings presented here were gathered between 1996 and 2003 during 39 factory visits at 24 factories of six HUD Code home manufacturers interested in improving the energy efficiency their homes. Factory observations typically showed that building a tighter duct system was the most cost effective way to improve the product's energy efficiency.

"The more we get out of the world the less we leave, and in the long run we shall have to pay our debts at a time that may be very inconvenient for our own survival." - Norbert Wiener
Introduction: The world's energy and environmental crises are inextricably linked. The processes of extracting, processing, and burning fossil fuels generates copious pollution of air, water, and land. Fossil-fuel-derived energy lies at the heart of other environmental problems. Fossil energy powers the bulldozers clearing rainforests. It runs the tractors and other farm equipment of industrial agriculture, compacting and mineralizing soils thus increasing …

Qualitative And Statistical Analysis Of The Florida Photovoltaic Rebate Program, Florida Solar Energy Center, Jennifer Szaro
FSEC Energy Research Center®
The Florida Photovoltaic (PV) Rebate Program, which began in March of 1999, has led to the installation of 52 utility interactive PV systems in seven electric utility service territories. The Program offered $4 per installed DC Watt to Florida electric consumers who installed grid-connected photovoltaic equipment in accordance with a series of quality control requirements developed and administered by the Florida Solar Energy Center. All rebated installations are currently being monitored in an effort to collect statistically significant reliability, performance and cost data on grid-connected PV systems. Funding for this program was provided through a one-time grant from the Florida …

You need special tools to design high-performance homes - residences where energy efficiency creates greater comfort, health, and energy savings. Making decisions about energy efficiency requires the accurate calculation of energy use and demand, and the comprehensive evaluation of proposed improvements.
A new software tool helps meet these requirements. EnergyGauge USA, an hourly simulation tool for the design and analysis of high-performance homes, performs detailed hourly simulation analysis for energy use, ratings and code calculations. Version 2.0 adds many features to the first-generation product, including thermal mass, photovoltaic (PV) system simulation, solar water heating, and detailed hourly outputs.

Fsec Approved Solar Energy Systems: Domestic Hot Water And Pool Heating, Florida Solar Energy Center, John Harrison
FSEC Energy Research Center®
This listing contains Florida Energy Factors for solar domestic hot water systems that have been approved by the Florida Solar Energy Center (FSEC) for use in the State. These energy factors represent the dimensionless ratio of the hot water energy made available by each approved system divided by the electrical energy used by the system. The Florida Energy Factor (FEF) is used to determine hot water credit multipliers for residential solar water heating systems in the 1993 Florida Energy Efficiency Code for Building Construction. The FEF can also be used to compare the efficiency of solar water heating systems with …
Air Handler Leakage: Field Testing Results In Residences, Florida Solar Energy Center, James Cummings
Air Handler Leakage: Field Testing Results In Residences, Florida Solar Energy Center, James Cummings
FSEC Energy Research Center®
Testing was performed to characterize air leakage in 30 air handler cabinets and at connections to supply and return ductwork. Operating pressures were measured in the air handler and plenums. Q 0.1 (Q 25) in the air handler averaged 23.9 cfm (11.3 l/s) in 30 homes. Leakage at the return and supply ductwork connections averaged 3.9 Q 0.1 (1.8 l/s Q 25) and 2.2 Q 0.1 (1.0 l/s Q 25), respectively. Actual return side leakage of 77.5 cfm (36.6 l/s) and supply side leakage of 3.1 cfm (1.5 l/s) are calculated based on Q 0.1 (Q 25) and measured operating …
