Solar Panels And Their Implementation In The Ubt Campus, Gentian Hyseni

UBT International Conference

Every day more and more demand for electricity in our country are growing, to meet these requirements, avoiding the generation of electricity from coal, as the production of electricity from coal, damages the environment and our health, we must invest in production of electricity from renewable energy from wind, sunlight etc. At pre-sent, energy from non-renewable resources such as fossil fuels or fissionable materials accounts for over 92% of the world energy usage. In addition, energy generation based on burning of fossil fuels has caused an increase in carbon dioxide (CO) and other gas emissions, leading to global warming. A …

Importance Of Energy Efficiency In Power Engineering, Ines Bula, Edin Bula, Diellza Berisha

UBT International Conference

This paper aims to show the importance of energy efficiency in the power engineering, that it is essential to all areas of the economy and society, as well as for the environment. While saving energy always involves certain sacrifices from the usual habits, efficient use of energy has led to increased quality of life, greater competitiveness of companies and the economy as well as energy security. Energy sources that are most in use today are based on the combustion of fossil fuels, and supplies of these fuels have their limitations and should be used more efficiently, thus improving energy efficiency …

Why Doesn't 25 Years Of An Evolving Energy Code Make More Of A Difference?, Florida Solar Energy Center, Charles Withers, Jr.

FSEC Energy Research Center®

This paper was presented at the 2015 Behavior, Energy and Climate Change Conference (BECC). New and more stringent building energy codes are implemented with the assumption and expectation that significant energy conservation will occur. While simulation and various analysis methodologies may be reasonably sound at estimating the energy impact, the actual impact is largely dependent upon new code enforcement and occupant behavior. This work is based upon the research question: Do homes built to a newer energy code deliver measurable energy savings compared to homes built to a much earlier energy code? This residential research study was focused on comparing …

Creating A New Model To Predict Cooling Tower Performance And Determining Energy Saving Opportunities Through Economizer Operation, Pranav Yedatore Venkatesh

Masters Theses

Cooling towers form an important part of chilled water systems and perform the function of rejecting the heat to the atmosphere. These systems are often not operated optimally, and cooling towers being an integral part of the system present a significant area to study and determine possible energy saving measures. Operation of cooling towers in economizer mode in winter and variable frequency drives (VFDs) on cooling tower fans are measures that can provide considerable energy savings. The chilled water system analysis tool (CWSAT) software is developed as a primary screening tool for energy evaluation for chilled water systems and quantifies …

Maximum Energy Efficiency Cost Effectiveness In New Home Construction, Florida Solar Energy Center, Philip Fairey

FSEC Energy Research Center®

EnergyGauge® USA (v.4.0.00) is used to examine the cost effectiveness of high performance homes that are improved to significantly exceed the minimum requirements of the 2015 IECC. The objective of the study is to determine the maximum level of energy efficiency that can be considered cost effective to the consumer. For these purposes, it is the cost effectiveness of the entire package of measures that is considered by the analysis rather than the cost effectiveness of individual measures. Optimization and rank ordering of the individual improvement measures in the package is not considered by the analysis.

Energy Agile Cluster Communication, Muhammad Zain Mustafa

Masters Theses

Computing researchers have long focused on improving energy-efficiency?the amount of computation per joule? under the implicit assumption that all energy is created equal. Energy however is not created equal: its cost and carbon footprint fluctuates over time due to a variety of factors. These fluctuations are expected to in- tensify as renewable penetration increases. Thus in my work I introduce energy-agility a design concept for a platform?s ability to rapidly and efficiently adapt to such power fluctuations. I then introduce a representative application to assess energy-agility for the type of long-running, parallel, data-intensive tasks that are both common in data …
