Industry Guide To Selecting The Best Residential Window Options For The Florida Climate (Revised), Florida Solar Energy Center, Ross Mccluney

FSEC Energy Research Center®

It used to be said that windows are little more than holes in the insulation. It is true to some extent that poorly insulated and drafty windows in certain climates defeat the purpose of wall insulation. However, modern high performance windows are almost as good as opaque insulated wall sections, at least in terms of total energy savings over long periods of time. In some cases, they can be shown to actually out-perform insulated walls. Of course, they have the priceless additional benefits of providing views to the outdoors and natural daylight illumination indoors important issues of quality and comfort. …

Moisture Problems In Manufactured Housing: Probable Causes And Cures, Florida Solar Energy Center, Neil Moyer

FSEC Energy Research Center®

A significant number of new manufactured houses built to HUD code and located in the hot, humid Southeast are experiencing moisture problems. Soft wallboards, buckled floors, damaged wood molding and extensive mold growth are the most common symptoms. These problems do not respond to the standard service and repair strategies for water intrusion

At the request of four manufacturers, over twenty-five such moisture damaged homes were investigated in 1999 and 2000 to determine likely causes. One time blower door, duct tightness and pressure differential measurements were performed on all homes. Field data on ambient, crawlspace, belly and house temperatures and …

Preliminary Evaluation Of Energy-Efficiency Improvements To Modular Classrooms, Florida Solar Energy Center, Danny Parker

FSEC Energy Research Center®

The objective of our investigation is to evaluate innovations that would enable modular classroom builders to improve the energy performance of their classrooms. We investigate improved insulation, better windows, daylighting, cross-ventilation, sensible and latent heat recovery of ventilation air and light colored surfaces and radiant barriers for cooling dominated climates. The tasks associated with this work are as follows:

• Create a simulation software.
• Establish a baseline reference building using a standard modular classroom building.
• Parametric evaluation of the impact of ventilation and school schedule on energy use.
• Determine the feasibility of improving insulation and envelope systems.
• Determine the feasibility of …

Fpc Residential Monitoring Project: New Technology Development Radiant Barrier Pilot Project, Florida Solar Energy Center, Danny Parker

FSEC Energy Research Center®

The FPC Monitoring project has evaluated radiant barrier systems (RBS) as a new potential DSM program. The objective was to examine how the retrofit of attic radiant barriers can be expected to alter FPC residential space conditioning loads. An RBS consists of a layer of aluminum foil fastened to roof decking or roof trusses to block radiant heat transfer between the hot roof surface and the attic below. The radiant barrier can significantly lower summer heat transfer to the attic insulation and to the cooling duct system. Both of these mechanisms have strong potential impacts on cooling energy use as …
