Introduction What is Solar Energy Solar energy is the energy of the sun falling onto earth. The amount of energy received from the sun is much greater than the amount of energy that can be consumed by people. The sun is located 148 million kilometres away from the sun, however it produces more energy in four hours that the entire human race does in one year. This energy gives life to this planet and without it; humans, animals, plants etc. would not be able to survive. Generations have used glass

Solar thermal energy is dead! A solar thermal heating system can cost upwards of $7,000 to install and it most likely won't even save you too much money. This is why many people debate over whether they should use a solar thermal water heating system, because they think they are saving money, or an inexpensive traditional water heating system. A traditional heating system is a system that is powered off of electricity, gas, oil or some other fuel. A solar thermal heating system uses the energy from
House originated. The house was the foundation for affordable and efficient housing through the incorporation of new technologies during those times. The TVA tested new materials as well as new technologies within the realm of municipal electricity, water, and sanitation. The New Norris House is a modern days take on the idea of what the original Norris House sought to accomplish during its time. The New Norris House takes on the challenge of creating an affordable and sustainable building approach
The water heater is very important because it supplies heat to the whole house. The benefits between hybrid water heaters and solar water heaters are they both have cash incentives which help homeowners save money and they both save resources. There are many benefits of using solar water heaters. Sunlight is free and environmentally friendly and this planet has so much to use(“Getting better acquainted”). The sun’s energy is renewable, suns energy is all over the world (“Getting better acquainted”)
A HP is thermodynamic cycle which is designed to use both heating and cooling functions. A thermodynamic HP cycle transfers heat from one reservoir (air) to another reservoir (water). There are four components of a HP which are evaporator, compressor,condenser, and expansion valve. The evaporator is a device like heat exchanger situated in the first reservoir. This evaporator makes possible heat from first reservoir in order to be transferred to a cold low pressure refrigerant. This heated refrigerant
For many years, the standard for residential household hot water systems has been an oil, gas, or electrical hot water tank that provides a reliable supply of water at a set temperature. The temperature gradient within the tank was thought to have little significance, as long as the output temperature was constant. It wasn’t until Sharp and Loehrke’s report [36] on the topic was published in 1979 followed by Hollands and Lightstone [37] ten years later that the potential rewards of thermal stratification
Introduction South Africa in most recent times has been plagued by an energy crisis. Due to the high energy demands placed on Eskom, it has been unable to cope with this high demand for energy and therefore unable to meet the energy demands of the domestic consumer. This has consequently led to unplanned power outages and scheduled load shedding by Eskom to ease the load demand. This is an obvious inconvenience for the citizens, it is therefore in their own best interest to assist in resolving the
and businesses that uses a large amount of electricity. An AC system represents half of the energy use in a building (Perez-Lombard 2011). Although it is hard to establish a universal system design due to the differences in building design, HVAC (heating ventilating and cooling) units are becoming more efficient then they were in the past. Modern day systems can intelligently pump air into rooms based on occupancy, thus eliminating the need to cool or heat an unoccupied room and dramatically reducing

So You Have Water Damage – Now What? It might start as a small, ugly spot on your ceiling or wall that slowly grows over time but what you can’t see is the damage that is occurring behind the drywall. Like the tip of an iceberg, by the time you spot the signs of water damage it’s already too late. Chances are, if you’ve found this page you’ve got an ugly water spot somewhere in your home. Keep reading to learn what causes water damage, how to minimize additional damage and replacement costs, and
Solar Energy Introduction: The Earth captures around 342 W/m2 of energy from the sun. This energy is in the form of solar radiation, which the atmosphere reflects about 77 W/m2 and will absorb around 68 W/m2 of solar radiation annually. Therefore, the Earth’s surface is receiving, on average, about 197 W/m2 of solar radiation annually. This amount of energy received is roughly more than 10,000 times the amount of all energy humans consume per year. This energy can be used to produce electricity or
Solar Heating It seems self-evident that, as a global society, we must transition eventually from the nonrenewable fossil fuels we currently rely on to renewable sources of energy such as biomass, wind, and particularly solar energy. The latter, though it involves some difficulties, which we will discuss shortly, is especially attractive, I think, because its source is the energy provided by the sun, which is so vast that, according to some, “if it could be effectively harnessed, two days’ worth
INTRODUCTION Clean water is an important part in our life. We use water to bath, drink, wash and a lot more. Therefore, having a full and complete water system is important in a building. The common system that we need are cold water system and hot water system. Hot water has been an essential for our daily life. It is not only important in domestic uses, it is also important in commercial buildings. For example, offices, hotels and even hospitals. There are two types of hot water system that is commonly
combustion. These two drawbacks in addition to the growing concern of global warming has pushed for the development of more sustainable sources of energy, namely solar energy and its derivatives (i.e. wind power). Solar energy is appealing for its potential to meet all our demands, while proving to be a pollution free resource.(Bohn, 2009) Solar energy originates from the thermonuclear fusion reactions occurring in the sun. Leaving all the byproducts of the reactions behind in the sun, the energy that
in winter. It also provides air tightness, good thermal performance and mechanical ventilation. It reduces the amount for heating demand. A Passivhaus design includes: - Excellent levels of insulation with very little amount of thermal bridges - Good levels of air tightness - A mechanical ventilation to allow a high quality of indoor air - Internal heat sources and passive solar gains The Code for Sustainable Homes, which was introduced in 2007, is a national standard for sustainable design and the
A Passive solar system collects heat as the sun shines through the windows and is stored on thermal mass. It uses the sun’s energy for heating or cooling buildings. Future homes should be constructed with this system because its advantages outweigh its drawbacks with low emissions of CO2 or other pollutant, consists of little maintenance, and has positive long term effects such as low electric bills. This system releases low emissions of CO2 or any other pollutant because it takes advantage of a
ABSTRACT Water and energy are the two most essential things for the sustainable development of the world. There is an acute shortage of both energy and water, especially in the 3rd world countries. Desalination plays an important role to solve fresh water scarcity in different regions of the world. In India Solar distillation is very useful in rural area where fresh water is not easily available. Modified Solar Distillation Page 1 CHAPTER 1 - INTRODUCTION 1.1. Basic of solar and energy
are two types of resources, Renewable and Non-renewable resources. What is a Renewable Resource? A resource which can be replaced or use repeatedly in order to prevent from resource exhaustion. Some of the common examples are wood, leather, water, wind, solar energy and paper. What is a Nonrenewable Resource? A resource which is found in limited quantities as it takes a They don’t become exhausted over a period of time. They prevent carbon dioxide and greenhouse gases from releasing into the atmosphere
