Construction Ecology 3 A CASE STUDY OF THERMAL COMFORT IN A HOUSE 27th April 2013 TEH QING YANG C3102987 Page 1 1.0 Abstract An important aspect of building design process - the thermal comfort‚ is a state of mind which express thermal environment with satisfaction. In the modern days‚ most human will spend indoor than outdoor. In this report‚ problems will be chosen to be analysed based on a case study that relates to occupant thermal comfort and building thermal performance existed in a living

* The sun has produced energy for billions of years. Solar energy is the sun’s rays (solar radiation) that reach the Earth. This energy can be converted into other forms of energy‚ such as heat and electricity. * In the 1830s‚ the British astronomer John Herschel famously used a solar thermal collector box (a device that absorbs sunlight to collect heat) to cook food during an expedition to Africa. Today‚ people use the sun’s energy for lots of things. solar energy can be used to: * Heat

Solar Energy Introduction With the unlimited energy we receive from the sun‚ solar energy has the capabilities to meet the endless demand of energy and electricity both here in the United States and worldwide. Solar Energy is the one of a few energy sources that emits no carbon dioxide into the atmosphere at all. When comparing the cost and benefits of solar energy to other energy sources it is clear that solar energy is the most viable form of energy possible. With renewable energy becoming

Energy is the ability to do work. It is important because every object we produce requires energy; for example transport‚ growth‚ and development. Humans and all other things get energy from the sun. Some forms of energy are kinetic‚ potential‚ thermal‚ chemical‚ electrical‚ and mechanical. Kinetic energy is the energy of motion. Potential energy is the energy which results from a position or configuration. Thermal‚ or heat‚ energy is the energy a substance or system has related to its temperature

more than enough energy to satisfy global energy needs for an entire year. Solar energy is the technology used to harness the sun’s energy and make it useable. Solar Energy is the energy from the Sun. The Sun is a big ball of heat and light resulting from nuclear fusion at its core. The nuclear reaction releases energy that travels outward to the surface of the Sun. Along the way to the surface the energy transforms so that by the time it is released it is primarily light energy. The two major

from http://www.researchandmarkets.com/reports/1285411/ Analysis of Solar Energy Industry in India & Its Future Prospects Description: The Indian solar energy sector has been growing rapidly‚ in the past few years‚ majorly due to Government’s initiatives such as tax exemptions and subsidies. Due to technical potential of 5‚000 trillion kWh per year and minimum operating cost‚ Solar Power is considered the best suited energy source for India. Today the Solar power‚ has an installed capacity of 9.84

renewable energy sources have long been debated‚ and examined but environmentalists such as Thomas Friedman believe that the use and production of sustainable energy resources is the way of the future and particularly vital to the advancement of the human race and the world‚ as we know it. As renewable energy sources such as solar power continue to become a more sought after approach for our everyday energy needs‚ engineers and environmentalists are developing innovative ideas for renewable energy and

alternative energy : bio fuel - "Ethanol in the Race of the Bio-Fuels " By: Thomas Dwyane Much talk has been going on about the use of the so-called alternative fuel sources in order to answer the demand of preserving the environment. One of the highest possible sources of this alternative fuel is ethanol‚ or that fuel which is derived from corn. Ethanol‚ also known as ethyl alcohol or grain alcohol or more commonly referred to simply as alcohol‚ is a flammable‚ colorless‚ and slightly toxic chemical

First of all‚ we know that the sun and wind energy are the most advance alternative energy. Today‚ mankind are beginning to look for energy that will support their life for the next century. So I could not think other than sun and wind energy as the best alternative energy resources‚ however it still needs a lot of development. The sun radiates vast amount of energy‚ which nourishes all life on earth and is the driving force behind the planets weather patterns and other natural cycles. In order
