Several passive heating systems, if provided with proper ventilation, can ensure to provide cooling. Passive heating and cooling for houses can be done in several ways, one of which is called geothermal energy. Passing the water through pipelines via ground can achieve and distribute the heating and cooling all over the house. (more…)

Many readers may be unfamiliar with the way economists typically view the process of technological change, thus it is useful to first establish this common understanding. Furthermore, to understand the potential for public policy to affect energy efficiency, it is also necessary to understand the process through which technology evolves: invention, innovation, energy diffusion, and product use. (more…)

As the need for energy efficiency becomes more pronounced, the drive toward efficiency in the commercial sector will be impeded by its complicated mix of building sizes and uses, the complicated systems often used in commercial buildings, and the relative lack of understanding of operations factors impacting energy use and how to achieve efficiency.

Using blankets the width of your wall studs, insert the blanket between the studs and staple to the studs. (The job is easier if you start from the top and work down, just as you do when you wall- paper your home. What? You don’ t wallpaper your home? Well, after you master insulating from the top down, you can begin.) Be certain the insulation fits snugly against the top piece of framing. (more…)

Visual inspection is usually good enough for under roof insulation that is accessible, as in boiler rooms, pipe chases, and steam tunnels. If the insulation is intact, fits snugly, and remains dry, it is almost certainly doing its job. Damage that is serious enough to reduce the effectiveness of insulation is usually obvious. The only subtle case is where insulation may become wet from a leak in the equipment it surrounds. (more…)

There are typically costs of adoption that are not included in simple cost-effectiveness energy calculations. It is by no means costless to learn how a technological improvement fits into a home or firm or to learn about reliable suppliers. Even after basic information about a technology has been disseminated, the purchase price of a new product is only a lower bound on its adoption cost. (more…)

Steam is a great heat transfer medium simply because it’s easy to move inside your system. Steam heating is known to have a very high heat retention capacity. The heat capacity of steam is much bigger compare than that of water. Steam systems are frequently working on very low pressure and generally below 220F. (more…)

Loos presented its latest technology in steam boilers: the Universal U-MB. The innovative high-volume boiler water vapor to yield between 200 kg / h 2 t / h, is of interest primarily for small to midsize companies between business and industrial customers. (more…)

The gradual change in the energy consumption pattern of the United States from 1860 to 1990. In the mid-1800s, biomass, principally woody biomass, supplied over 90% of U.S. energy and fuel needs, after which energy biomass consumption began to decrease as fossil fuels became the preferred energy resources. For many years, a safe illuminant had been sought as a less expensive substitute for whale oils. (more…)

As a result of high and rising costs of fossil fuels and fossil fuels affect global environment concern , and by the reduction of greenhouse effect gases from burning causes (Kyoto Protocol), the heat recovery gain importance growing. A heat exchanger absorbs a significant portion of the heat energy of the gases generated during combustion of solid fuel, liquid and gas in the smelting process, heating, roasting, and drying. (more…)
