The Energy Star Home
The Energy Star label is awarded to products that promote energy-efficiency. New homes have been included in the Energy Star Program. Energy Star products must be at least 30% more energy-efficient than current regulations demand. The same energy requirements apply to the Energy Star Home as well. Such areas on a home that are targeted for improvement include: framing, ducts, windows, insulation, and HVAC. Although, the energy star program includes appliances and electronics, when applying the program to a home, only structural improvements are taken into consideration. It is possible for a home to receive an Energy Star Label but at the same time be filled with non-energy star appliances. Older homes can be upgraded to meet energy star requirements but such improvements might not necessarily be cost effective. Making upgrades during construction is cheaper than going back and modifying existing structures. I will focus on the new energy star home as well as cost effective upgrades to existing homes. These upgrades will not qualify the house as an energy star home but they will increase efficiency.
Energy star homes use reliable and established technologies and building practices to operate significantly more efficiently than homes built to the Model Energy Code. Every new house today is built to the Model Energy Code (MEC). This code varies for different parts of the country but new houses built must meet the minimum requirements of the Model Energy Code. These technologies and practices save the owners of energy star homes money on their utility bills. They also provide a home that is more comfortable, more durable, environmentally friendly, and cheaper to own. The up front cost of...

...w construction energy star homes make sense because during construction, upgrade costs are nominal. Old homes can be upgraded as well but it is not always necessary to receive an energy star label. Energy efficiency in homes can be increased even without meeting the requirements for an energy star home. The energy star label can be important for resale value but the true test of a home¡¦s efficiency can be measured by the utility bills.

Electricity is an interesting subject. There is so much you can learn from it, like how our lights turn on or how we make cell phones. This is all a mystery until we finally get a little bit of information in our brains. I've just read two articles, "Energy Story" and "Conducting solutions". I also watched a video called Hands-on Science with Squishy circuits. I learned so much valuable information from these resources.
The calculated hurdle rate includes a safety margin because the highest measure of Re is used. This is not to say that Re could never succeed .
LEED, or Leadership in Energy & Environmental Design, is a certification program for green buildings with stringent requirements for building energy efficient and environmentally responsible structures. Some requirements of this program include specific building materials, smart grid capable, gray water reclamation systems, green space minimums, high levels of insulation and low thermal transfer glass (US Green Building Council). Green buildings are a must if we are to sustain our current level of growth. Despite the higher initial cost of these buildings, the long term energy savings make these buildings a smarter choice for

During Classical Greece the Parthenon was built as temple to the Goddess Athena, as symbol of the state’s wealth and superiority, along with serving as the treasury. The architecture uses a bit of both Doric and Ionic orders. On the outside rim of the temple Doric columns, triglyphs and metopes are used but on the inside of the temple Ionic friezes were used. Both the metopes and friezes were completely filled with painted sculptures depicting the gods, Athenians, and conquered enemies. The themes center on gods or Athenians being victorious over chorus. One of the main stories shown in the Parthenon is the story of the Goddess of Wisdom, Athena being chosen as the patron Goddess of Athens over the Sea God, Poseidon. Poseidon was a war god who offered the people a beautiful but useless saltwater spring while Athena offered an olive tree. The people of Athens choose the olive tree symbolizing their culture valuing peace and prosperity over the chorus of war. The Parthenon also shows the Ancient Greeks value in mathematics and idealized perfection. The columns were carved to bulge slightly as well as tilting inwards, which creates the illusion that the columns were both straighter and taller than they were. Other illusions they used to give the appearance of perfection included arching in the middle just enough to ensure what would not pull and stop the eye from seeing the ends of the steps rise. Ancient Greeks valued their gods, perfection, mathematics, wealth and

The pathophysiological difference between rickets and gout is obvious. Rickets is a disease consisting of soft bone usually in children. The medical term for softening of the bone is osteomalacia and is the term used when describing rickets to a patient. The anatomy and physiology of rickets starts when the osteoid (bone appearance, structure) does not calcify correctly within the body. Inside the blood stream, vitamin D travels throughout the body until the liver is reached. When in the liver, vitamin D is converted to calcidiol (hardening substance) and pushed to the kidneys where the process ends. The kidneys transform calcidiol into the final form of vitamin D called calcitriol. Calcitriol absorbs calcium, magnesium, and phosphate. Rickets occurs when calcitriol is not present in the kidneys.
Today’s kitchen appliances are highly energy-efficient, which will help you save money on your next energy bill. Kitchen design also plays an important role in the kitchens overall appeal. Check out the following outdated kitchen designs, if you have one or more in your kitchen, it may be an indicator that your need to remodel.

Green, affordable housing shows an opportunity to decrease costs, such as utility and transportation costs, which can influence low-income people. After careful consideration, here are some common features used in affordable housing.
...rights, and therefore, the conflict itself. Had the British powers of the early 20th century been more clear in their language regarding the inherent rights of Palestinian Arabs, more closely monitored levels of immigration, or even paid more attention to the needs of the Palestinians, perhaps the conflict could have been nipped in the bud. As it grew, and other nations threw their hats into the ring, stronger action could have been taken against the settlement-building and subsequent refugee problem in the Palestinian territories. However, very little was done during the time when change could have been more easily exacted in the region; at this point, two very strong viewpoints have been established, it is now left up to the Israelis and Palestinians themselves to reconcile their differences, compromise their viewpoints, and restore amiable relations to the region.

The three crucial reasons why you should use solar energy is because of low maintenance, abundant, renewable energy, and due to it’s reducing of electricity costs.
In Ancient Greece, religion dominated their life, so it is understandable that their architecture would be dominated by their religion. Before Greece became many different city-states, they had kings, and they would build a room called a megaron to show they King’s authority. A typical megaron is a single chamber with a fire pit in the middle with a throne off to the side. This room opened up into a porch (portico) that had four columns in the front. After there were no more kings these megarons turned into temples. The fire pit, which turned into some type of altar or a place to show a sacrifice for that god, was now outside in front of the temple. The altar was now outside so people could see you make these sacrifices to their gods. The first Greek temples were made out of wood and were long rectangular buildings with a porch all the way around which was supported by columns made from tree trunks. A Greek temple consists of five basic parts: the pediment, entablature, columns, base, and the cella, or the inner sanctum. The pediment is triangular and would have a type of sculpture or ornament known as acreteria on each corner. An entablature consists of three parts: the cornice, frieze, and architrave, which holds up the pediment. The columns are the support between the entablature and the base. The base usually consists of three steps. The cella is the inner sanctum, which has different rooms with more columns for support. Each temple would have a cella but they were not identical.

For years man has relied on energy in order to be successful in life. The industrial revolution relied on coal for the new inventions brought into the world. Life as has never been the same since then. However since that time, there has been little done to improve on energy efficiency and humans still primarily rely on fossil fuels for energy. For over a hundred years the Earth has become more polluted and dirtier than ever before. Now, with new, innovative technology there is an opportunity to change that and to rely on renewable, cleaner sources of energy. The main source of energy for the world should be alternative energy instead of energy from fossil fuels.
