Energy And Economic Optimization To Achieve Near Zero Energy Homes In Europe: Implications Of Inclusion Of Lighting And Appliances, Florida Solar Energy Center, Danny Parker

FSEC Energy Research Center®

Achieving annual net zero energy use in homes has been demonstrated as feasible in dozens of monitored projects in the United States.[1] In particular, very low energy use homes in Europe have been proven within the Passivhaus approach.[2] Achieving 'nearly zero energy buildings' (NZEB) has also been established as a vital objective over the next decade within the European Union (EU) (Boermans et al., 2011). However, reaching this result at the lowest possible cost remains a key challenge around the world. Balancing renewable power generation with energy efficiency will be vital in Europe as anticipated by Voss, Musall and Lichtmeß.[4] …

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, …

Hers Index Scores As An Alternative Compliance Path For The 2015 Iecc, Florida Solar Energy Center, Philip Fairey

FSEC Energy Research Center®

The analysis presented here is an extension of a previous study on HERS Index Scores as they relate to various version of the International Energy Conservation Code (IECC) by the same author. This extension of the previous study is designed to examine the impact of advanced, ultra-high efficiency appliances and high efficiency HVAC systems on HERS Index Scores as they relate to reductions in the HERS Index Scores that may be used as 'tradeoffs' against best practice envelope efficiencies.

A Survey Of Energy-Efficient Compression And Communication Techniques For Multimedia In Resource Constrained Systems, Tao Ma, Michael Hempel, Dongming Peng, Hamid Sharif

Department of Electrical and Computer Engineering: Faculty Publications

Advances in wireless multimedia communication technologies enable new types of pervasive and ubiquitous applications such as mobile health care, environmental monitoring, facility monitoring and traffic surveillance. Among different factors concerned, energy efficiency is one of the most challenging issues in multimedia communication due to the resource constraints, and the requirements for high bandwidth and low transmission delay. In this survey, we provide a broad picture of the state of- the-art energy efficient techniques that have been proposed in wireless multimedia communication for resource-constrained systems such as wireless sensor networks and mobile devices.

Following the essential stages required for multimedia communication, …
