...the twentieth century, the annual changing of time that is designed to make the most out of summer and spring days by extending the daylight hours certainly seems like a good thing. Besides extending daylight, it’s also said to help with energy conservation and give people more time to rest. What if I told you that daylight savings time’s negative effects greatly outweighs its positive effects? It’s time to see just how useless and surprisingly detrimental daylight saving’s time and it’s accompanying piece of legislature really is. The most important claim to debunk about DST is if it really does lead to energy conservation. According to one of the facts listed in Source A, the whole reason that DST was adopted by the United States was to make an effort to save energy during World War 1. Ever since 1942, Americans have kept the same perception that DST does in fact help save energy. Source B states that “Studies done in the 1970s…that daylight savings time is in effect.” (Lines 7-10) These findings would be completely credible if they were relatively recent, but they aren’t. The most recent data, presented in Source F, gives the “first empirical estimates of DST effects on electricity consumption in the...

...Daylight Saving Time (DST) is a time where Americans move their clocks forward by an hour to extend daylight in the evening. However, there's evidence that supports the fact that Daylight Savings Time should stop being practiced in the United States. Daylight Savings Time should stop being implemented in the United States because it is bad for health, outdated, and decreases productivity. Daylight Savings Time should no longer be enacted in the United States because it is damaging to the health of the body. In an article from Time Magazine, by Lynne Peeples, the circadian rhythm is the body’s natural clock that controls when to be tired– this gets disrupted when going off schedule (Peeples). This disruption can minimize the amount of sleep one is taking– which, in turn, creates lots of problems when the person wakes up. Similarly, in a National Geographic article by Brian craftsmanship, changing the time by an hour can be bad for a person’s health due to changes in sleep cycle and immune system response (Handwerk). This means that Daylight Savings Time is bad for health because it delays the body’s defense mechanism due to less sleep....

...midnight for Daylight Savings Time? If something wasteful was costing you money would you want to continue doing it? What if it was bad for your Health? Each year millions of dollars are thrown out the window due to Daylight Savings Time. For the last 50 years we have had to move our clocks forward one hour during the spring, and push them back one hour during the fall. This process is called Daylight Savings Time, a concept that I along with many others feel is no longer practical and should be abolished. Daylight Savings Time was first conceived by Benjamin Franklin in 1784 as a way to conserve on candles (History of Daylight Savings Time-DST). When electricity came around many saw it as a way to conserve energy. Their...

...Daylight saving time was first proposed in 1895, but most countries have introduced it in the 1970s. From the very beginning, the idea has had its proponents and opponents. Many people claim that having to adjust clocks twice a year is not worthwhile, others, however, consider it an indispensable element of our lives. Daylight saving time may often prove beneficial. First of all, setting the clocks forward in spring causes evenings to be longer, as it provides us with an additional daylight hour. When the night falls later, people feel encouraged to go out more often and, consequently, to spend more money. Needless to say, a longer evening brings about the increase in consumption, which boosts the economy. In addition to that, time shifting...

...Sensors & Controls SECTION 8 Tips for Daylighting with Windows OBJECTIVE Design and install a control system to dim lights and/or turn them off when there is adequate daylight. • Reduce lighting energy consumption with automatic controls. • Use a lighting specialist for best results with the control system. KEY IDEAS General • Sensors “measure” light by looking at a wide area of the office floor and work surfaces from a point on the ceiling. The sensor’s signal is then used by the control system to dim or turn off the electric lights according to the available daylight. These simple components are needed to save energy in daylighted spaces. • Controls can respond to many variables. To save lighting energy, controls are typically designed to respond to daylight and a host of other inputs (e.g., occupancy sensors, weekend/holiday/nighttime schedules, etc.). • Include all control documentation in the construction documents. This should include clearly developed control schematics, control sequences, calibration instructions, maintenance plans and checklists, and clear testing procedures. • Lighting controls and sensors must be properly calibrated and commissioned prior to occupancy. This helps ensure energy savings and reduces the likelihood of complaints from occupants. • Take special care to document integrated control systems. Control schematics are critical where different building systems (e.g., lighting, mechanical, etc.) come together. Identify...

...Daylight Saving Time(DST) is moving the clock ahead one hour at spring season and moving it back at fall season. The issue that Daylight Saving Time is a good idea really depends on who you ask. In fact, it is indeed an interesting issue to throw out there for discussion. Proponents of DST believe that it saves energy, promotes a healthy life, and reduces traffic accidents. However, many opponents appear to disagree with all their contention. Proponents of DST have pointed to energy conservation as the most important reason. They believe that DST should serve as an incentive for people to spend more time outdoors. If people are outside, they are not inside turning on lamps, appliances and electronics. Unfortunately, this is clearly not true. Recent studies point out that DST might reduce the US electricity usage by 1% compared with standard time. Other estimates, by the National Bureau of Standard, suggest it has zero effect. Also, proponents have claimed that DST is more likely to promote a healthy life. They believe that DST does provide extra daylight in the evening, and that may bring with it increased physical activity and reduced incidence of depression. Nevertheless, studies show that there are spikes in suicide rates and an increase in the number of recorded heart...

What can be popping up in your mind when you hear the term “Internet of Things (IoT)”? refers to the Machine-to-Machine Technology, the Industrial Internet, Internet of Everything, and probably a few other phrases. Kevin Ashton first came up with Internet of Things in The idea simply 1 1998, which involved wireless communications and networking; and the concept has been attracting extensive attention recently. IoT does go beyond machine-to-machine communications (M2M) and covers a variety of protocols, domains, and applications[1]. It is different with human-to-human or human-to-machine interaction. The interconnection of these embedded devices (including smart objects), is expected to conduct in automation in nearly all fields, while also enabling advanced applications like a Smart Grid[2]. The Honorable Sir Charles Kuen Kao, was born in 1933, known as the “Father of Fiber Optics Communications”, was jointly awarded the 2009 Nobel Prize in Physics for “groundbreaking achievements concerning the transmission of light in fibers for optical communication.”[3] Simply put, IoT is a network of physical objects (i.e. refrigerators) that contain embedded...

...Mercedes Benz AMG Mercedes Benz is an amazing car brand with great horse power and a beautiful look. The brand offers different styles of cars from Sedans to SUVS and sports cars. One of the nicer versions is the C63 AMG. Three important aspects of the car are the Engine, the Transmission, and the LED headlights. This essay will explain the features of each and why the features make the AMG a great car. The Engine of the AMG is very important for the car’s function and drive. The 4.0-liter V-8 biturbo engine of the AMG is the first sports car engine in the world which has the turbos inside the V of the engine. (AMG Driving Performance , 2015). It also has dry sump lubrication, which is “a lubricating motor oil management method for four-stroke and large two-stroke piston internal combustion engines that uses additional pumps and a secondary reservoir for oil—as compared to a conventional wet sump system, which uses only the main sump below the engine and a single pump.” (Dry Sump , 2015). This makes the engine more efficient because of the prevention oil-starvation at high g loads, and because their lower center of gravity positively affects performance. (Dry Sump , 2015). The head of engine design at AMG stated: “With the new AMG 4.0-litre V8 biturbo engine, we present a fascinating and powerful sports car engine, which also achieves the next step in efficiency due to numerous measures.” (Mercedes Benz, 2014). The advantages of the engine are that the eight-cylinder engine...

In this research, Learning Team D looks at HECO to determine what actions they need to take to solve this solar issue. First the team provides research questions and hypotheses as well as variables and ethical considerations HECO should think about. Second they discuss the significance, scope, magnitude, and feasibility. Last they end with the research’s purpose and teams’ conclusion. Research Questions What type of action is involved to build smart grids and provide installation of advanced meters in neighborhoods across Oahu? How will smart electric grid technology improve electric service? At HECO, management focuses on solving the problem by upgrading their technology system to provide adequate electric service in urban areas of east Honolulu. HECO completes the East Oahu Transmission Project to improve the electric systems responsiveness and efficiency. Smart grids approach would save money and it allows HECO to limit the construction impacts to the surrounding community (Hawaii’s Energy Future, 2012). Hypotheses In this research, Team D will use the explanatory hypotheses. Cooper and Schindler (2011) describe explanatory hypotheses like an independent variable and a dependent variable because a change in one variable causes the other variable to change as well. An increase in the cost of imported fuel leads to an increase interest in renewable energy. An...

...ENVIRONMENTAL SCIENCES 2 INTEGRATED DESIGN MUHAMAD NAZMI FITRI BIN ABD AZIZ 2014406812 INTEGRATED DESIGN Integrated design is a collaborative method for designing buildings which emphasizes the development of a holistic design. INTEGRATED DESIGN IMPROVES THE ENERGY PERFORMANCE OF BUILDINGS. The conventional definition of integrated design is that project team members from all disciplines work together early and often throughout the project design process. ORIGINS OF MODERN-DAY INTEGRATED DESIGN Integrated design has become a buzzword in the green building world. Everyone claims to do it, although not everyone understands it in the same way, and not everyone is successful at it. DESIGN FEATURES THAT BENEFIT FROM INTEGRATION * DAYLIGHTING * GREEN ROOFS * EXPOSED THERMAL MASS Conventional building design usually involves a series of hand-offs from owner to architect, from builder to occupant. This path does not invite all affected parties into the planning process, and therefore does not take into account their needs, areas of expertise or insights To a growing number of building owners and designers, this linear process needs to change. The process they prefer is called integrated design. It’s built around better communication and more planning. Through the use of integrated design, owners and designers are able to build better, less expensive buildings. The problem is that even though integrated design has been around for nearly a decade...
