Evaluating Moisture Control Of Variable-Capacity Heat Pumps In Mechanically Ventilated, Low-Load Homes In Climate Zone 2a, Florida Solar Energy Center, Eric Martin

FSEC Energy Research Center®

The well-sealed, highly insulated building enclosures constructed by today's home building industry coupled with efficient lighting and appliances are achieving significantly reduced heating and cooling loads. These low-load homes can present a challenge when selecting appropriate space-conditioning equipment. Conventional, fixed-capacity heating and cooling equipment is often oversized for small homes, causing increased first costs and operating costs. Even if fixed-capacity equipment can be properly specified for peak loads, it remains oversized for use during much of the year. During these part-load cooling hours, oversized equipment meets the target dry-bulb temperatures very quickly, often without sufficient opportunity for moisture control. The …

Transportation Planning For Electric Vehicles And Associated Infrastructure, Florida Solar Energy Center, David L. Block

FSEC Energy Research Center®

Planning is the key to successful adoption and deployment of any new technology, and it is particularly important when that advancement involves a paradigm shift such as electrified transportation. At its core, electric transportation is largely a technology deployment. The vehicles and supporting infrastructure are unique to this mode of transportation; requiring new and specific planning and policies to support their deployment. This EVTC project brings together these planning elements and their role in the future U.S. transportation network. The project results are presented in five planning related subject areas: (1) Identification of 14 of the 22 EVTC program topics …

Achieving Challenge Home In Affordable Housing In The Hot-Humid Climate, Florida Solar Energy Center, David Beal

FSEC Energy Research Center®

The Building America Partnership for Improved Residential Construction (BA-PIRC) worked with two affordable housing builders who pursued and achieved CH certification. Both builders needed very few changes to reach CH; however, both were already certifying homes under the ENERGY STAR® for Homes Standard v.3.1. Habitat for Humanity affiliates’ mortgage terms are 0% interest over a 30-year mortgage to qualified buyers. To improve relevance of the study to the general homebuilding community, the cost-effectiveness calculations herein are based on a code-minimum reference rather than the builders’ standard practice (ENERGY STAR), and projected first year cash flow is provided for both the …

Ventilation in residential buildings is one component of an effective, comprehensive strategy for creation and maintenance of a comfortable and healthy indoor air environment. The study described in this white paper is based on building energy modeling with an important focus on the indoor humidity impacts of ventilation. The modeling tools used were EnergyPlus version …

Current Best Practices For High Performance, Deep Energy Retrofits In Florida Affordable Housing, Florida Solar Energy Center, Janet Mcilvaine

FSEC Energy Research Center®

In the fall of 2009, researchers at the Florida Solar Energy Center (FSEC) began working with affordable housing entities that were conducting major renovation projects in unoccupied, foreclosed homes. The study was funded by the Florida Energy Systems Consortium and the U.S. Department of Energy's Building America program. When components and equipment were being replaced because they were worn out, researchers provided savings projections for higher-efficiency choices. Savings were also projected for improvements that were strictly for energy efficiency, such as adding ceiling insulation. The best practices summarized in this document are a mixture of assessment, design, specification, quality assurance, …

Energy Retrofit Field Study And Best Practices In A Hot-Humid Climate, Florida Solar Energy Center, Janet Mcilvaine

FSEC Energy Research Center®

In the U.S. Census Bureau's Southern region, housing starts ranged from 4.6 to 5.9 million per decade from the 1970s through the 2000s, nearly twice as many as any other region across all decades. The potential for energy savings in these homes is vast, perhaps our most available untapped resource for reducing energy needs. This study was conducted in central Florida, which forms part of the Census Bureau's Southern region. It examines efficiency retrofit opportunities, typical renovation practices, and pathways for achieving U.S. Department of Energy (DOE) goals for existing homes in that region.

Green And High Performance Factory Crafted Housing, Florida Solar Energy Center, Stephanie Thomas-Rees

FSEC Energy Research Center®

In the U.S., factory-built housing greater than 400 square feet is built either to the U.S. Department of Housing and Urban Development (HUD) code for mobile homes or site-built codes for modular housing. During the last few years, as the production of HUD code housing has dwindled, many leading edge factory builders have started building modular homes to compete with site-built housing and stay in business. As part of the Building America Industrialized Housing Partnership (BAIHP) we have assisted in the design and construction of several 'green' and high performance modular homes that Palm Harbor Homes, Florida Division (PHH) has …

This paper identifies the imperative for and value of creating disaster-resistant homes and communities. The use of renewables, the application of distributed generation, implementation of energy-efficient building designs and construction of disaster-resistant structures can minimize the destruction of property, cost of recovery and disruption of lives. Through enhanced construction practices and the use of solar …

Disasters: Photovoltaics For Special Needs, Florida Solar Energy Center, William Young

FSEC Energy Research Center®

The National Hurricane Center tracks the path of a hurricane to determine where it will make landfall. People in harm's way are informed of its approach and the need to evaluate options to prevent injury and protect lives. One of the many groups of people at high risk is those with special needs. They have health conditions that require special care. Before a disaster, these individuals live in hospitals, care facilities and homes. During and following a disaster, many would be moved, along with their supplies, equipment and a caretaker, to a special needs shelter. Others would stay with relatives …

Florida's Energy Future: Opportunities For Our Economy, Environment And Security, Florida Solar Energy Center, Philip W. Fairey

FSEC Energy Research Center®

The future of Florida's economy, environment and security is inextricably intertwined with our energy use decisions. Our state has one of the nation's fastest growing populations, promoting rapid expansion of an energy industry that imports its fuel supplies. Florida exports approximately $32 billion per year for these energy fuels. Moreover, the Florida economy depends critically on tourism and agriculture, and the fuels and energy products that maintain them. Our pristine environment is the primary natural resource supporting this unique economic engine and the adverse effects of our rapidly growing energy use now stress it. Our State's economic well-being and security …

Complying With Florida's Green Land Development Standard: Case Studies And Lessons Learned, Florida Solar Energy Center, Robin Vieira
