Measured Energy Savings Of A Comprehensive Retrofit In An Existing Florida Residence, Florida Solar Energy Center, Charles Withers, Jr.

FSEC Energy Research Center®

Simulation analysis suggests that electricity consumption can be reduced up to 40% in existing Florida homes with judicious use of methods to reduce loads, as well as more efficient equipment. To test this theory, an all-electric home was located in Miami, Florida upon which to perform a variety of retrofits. The total annual electricity consumption in the one year base-line period preceding the study was 20,733 kWh. Although high, this is not unusual for a South Florida home with a swimming pool since pool pumping often accounts 3,000 -4,000 kWh per year. Detailed instrumentation and metering equipment was installed in …

Energy Needs During Disasters: Workshop Summary Report, Florida Solar Energy Center, Gerard Ventre

FSEC Energy Research Center®

When natural disasters, such as hurricanes, earthquakes and floods, occur, thousands of people can be left without homes, electrical power, communications, potable water, and food storage capabilities. Adequate electrical power is imperative for both disaster relief operations and community rebuilding. However, the disaster may have disrupted the commercial power supply to a community, requiring disaster relief agencies to rely on alternative sources of power. Photovoltaic-powered equipment provides electrical power which is renewable, quiet, and safe, and which can be used for many essentials of disaster relief efforts, such as refrigeration, communications and lighting. However, at present, photovoltaic (PV) technology is …

Demonstration Of Cooling Savings Of Light Colored Roof Surfacing In Florida Commercial Buildings: Retail Strip Mall, Florida Solar Energy Center, Danny Parker

FSEC Energy Research Center®

A series of tests were conducted in seven retail shops in a strip mall in Cocoa, Florida to examine how roof whitening would impact air conditioning load. The roof of the strip mall was conventional: unsurfaced galvanized corrugated metal with R-11 insulation suspended by purlins underneath. Below the insulation was the roof plenum which contained both the air handler and duct air distribution system. Cooling was accomplished in each shop by a dedicated direct expansion air conditioning (AC) system between 3 and 4 tons in size. Each had its air conditioning metered for half of the summer in a baseline …

Controlling Ventilation And Space Depressurization In Restaurants In Hot And Humid Climates, Florida Solar Energy Center, Charles Withers, Jr. Sep 1997

Controlling Ventilation And Space Depressurization In Restaurants In Hot And Humid Climates, Florida Solar Energy Center, Charles Withers, Jr.

FSEC Energy Research Center®

Testing was performed in 9 restaurants to identify uncontrolled air flows and pressure imbalances, building and duct system airtightness, building air barrier location, pressure differentials, building air flow balance, and ventilation rates. All restaurants are depressurized under normal operating conditions, ranging from -1.0 to -43 pascals. Space depressurization is a function of exhaust fan flow rates, missing or undersized make-up air, intermittent outdoor air caused by the cycling of air handlers, dirty outdoor air and make-up air filters, and building airtightness. Ventilation rates were found to be high, generally exceeding ASHRAE 62-1989 minimum recommended levels. Pressure imbalances and excessive ventilation …


Moving Mountains With Good Research - A Case Study, Florida Solar Energy Center, Ross Mccluney Jul 1997

Moving Mountains With Good Research - A Case Study, Florida Solar Energy Center, Ross Mccluney

FSEC Energy Research Center®

Mountains can be moved by good ideas based on good research. A wonderful example comes to us from, of all things, the Naval Facilities Command (NAVFAC), headquartered in Washington, DC. This agency of the Department of Defense is responsible for some $5 billion per year in new and retrofit construction, with naval facilities all over the globe. The federal government alone is responsible for $50 billion per year of construction, which Terry Emmons of NAVFAC claims is half of total U.S. construction. It seems that the Navy has 120,000 buildings around the world, some buildings, or groupings, are the size …
