Heating

Energy performance of the original house is not terribly bad but not satisfied, either. It wastes a huge amount of energy in cooling the living area. Strategies of achieving better passive heating and cooling will be illustrated as following. Reducing cooling energy consumption will be emphasized in designing the new house. The original orientation (315 degrees with living room faces south-west) resulted in excessive heat gain during summer, especially in the afternoon, and insufficient heat…

energy consumption is done principally by buildings in the U.S. This research intends to decrease the percentage of carbon emission by developing zero carbon homes. Berry,S. et. al. (2013) define zero carbon homes as having no need for fossil fuel for heating, cooling, and lighting; being neutral for twelve months period; and being energy efficient on-site. In addition, energy efficiency is the most effective way of creating zero energy homes (National Institute of Building Science, 2013), with…

However, due to the same reason, the heat gained by the airflow passing through the cavity can less contribute to the reduction of heating demand in buildings. For the dimension of the air cavity, optimisation results show that the minimum practical depth for the cavity is an ideal option regardless of the site location. In addition, according to Table 3, the electrical efficiency of…

becomes difficult in harsh weather, fighting against the forces of nature is definitely not an easy job. Colder climates tend to bring a number of problems and if people are not prepared for it then the overall problem can be seriously aggravated. Heating is necessary in such climates in order to fend off the troubles of the weather which can make life miserable. In order to overcome the challenges of the weather warmth is essential. Science and technology have improved by leaps and bounds in…

further away from each other resulting in the substance occupying more space and changing state. (Sarah Friedl. 2003-2016) (BBC Bitesize. Energy transfer by heating. 2014) Solid: Particles within a solid have a really low amount of kinetic energy, the electrons move in the atoms of a solid this causes them to vibrate in fixed positions. Heating a solid to a certain extent, depending on the solid, will cause the solid to melt into a liquid or will cause sublimation to occur where the solid…

-Evaporating dish -Water -Small beaker -Heating plate -Scale -Tongs Safety precautions - For this experiment you had to make sure you paid extra attention when using the heating plate. We had to heat the unknown hydrated salt for about 5 minutes. When doing this it was important that we had a timer so that we don't exactly overheat it. Overheating it can cause you're beaker to crack and possibly spilling hydrated salt on you. Also when handling the beaker when its done heating make sure you…

So, you're thinking about finishing that basement or bonus room and your calculating the costs. A major expense when it comes to the finishing construction of rooms in completed homes is the heating equipment or the expansion of an existing system. It can be a real hassle, not to mention extremely costly when it comes to running duct work to the new space. Or maybe you just have a bathroom that no matter what you do, stays a little cool. There's actually a simple calculation that will help you…

By measuring out two grams of our unknown, and heating it up until the difference of the mass of the test tube and the anhydrous residue subtracted to 0.002g, we were able to calculate the percent water in the two possible unknowns, and then our unknown, to figure out which unknown we were given. Since our percent water was 44.9%, we concluded that our unknown is Zinc Sulfate. A possible error as to why our calculated percent water was not exact to the theoretical percent water was most likely…

Heating, ventilation, and air conditioning (HVAC) systems in commercial buildings are responsible for consuming more than 40 percent of the total energy usage. Keeping it running properly and at peak efficiency is one of the important steps in energy management. A good system maintenance is more than just controlling energy usage. Besides people comfort, today's buildings depend on HVAC systems for other important reasons too. For example, most telecommunication systems need specific…

tread to be on that green tire to be shaped. The outside of the circular tread face is in contact with the pre-heating or curing molds inside circumference. The tread shapes on the tire is formed by ribs and/or lugs on the inside of the circular tread face. The circular tread face has holes to let the gasses produced by the tire out. The circular tread face is supported in the pre-heating or curing…
