Cool roofs are included as a performance option in Title 24. Refer to Section 10-113 for information on certification and labeling requirements for reflectance and emittance of cool roof products. For the prescriptive compliance approach in the energy efficiency standards, view section 118 of Title 24. Sections 141, 142, and 151(b) outline the performance approach. For the latest applicable Standard see: www.energy.ca.

It is always best to be energy efficient, but if not, it is still best to use radiant because you will use less energy and spend less money. You may need a supplemental heat source on very cold days, but radiant heating is the only way to be truly comfortable in a room that is not energy efficient. See similar questions...

Energy conversion efficiency is an expression of the amount of energy produced in proportion to the amount of energy consumed, or available to a device. The sun produces a lot of energy in a wide light spectrum, but we have so far learned to capture only small portions of that spectrum and convert them to electricity using photovoltaics. So, today's commercial PV systems are about 7% to 17% efficient, which might seem low. See similar questions...

Due to their superior insulating properties, green roofs have consistently been proven to reduce heating and cooling costs by up to 25% and 50%, respectively, for the floor directly below the roof. Rooftop surface temperatures impact not only the temperatures within the building, but also the amount of energy necessary to heat and cool the building to the desired temperatures. Plants transform heat and soil moisture into humidity, naturally cooling the building. See similar questions...

Tests conducted by The Log Homes Council of the NAHB found log homes to be equal to conventional home construction. Log home owners generally report lower heating and air conditioning costs. See similar questions...

I'll give you the obligatory speech about watts VS. volume so that you don't get all caught up in the 100+ watts thing. The way that watts translate into decibels is in powers of 10. That being the case, if you want to do twice as loud, you need to go 10x higher in wattage. The difference in volume between 100W and 50W is actually only 12% less or so. HALF the volume of 100W is actually 10 watts, and TWICE the volume of 100w is actually 1,000 Watts. See similar questions...

The human body consists of billions of cells and the function of these cells determines our level of health. For human cells to operate healthily, they require fuel from various foods. A healthy cell provides the body with energy but as this energy is depleted, the cell becomes drained and more fuel must be supplied to the cell to achieve high levels of energy once more. The human cell can be likened to a re-usable battery. See similar questions...

First-time freshmen and transfers who attend New Student Orientation will be able to register for fall classes the next business day after orientation, providing your fees are paid and holds are cleared. This early registration gives you a wider selection of courses from which to choose. Students who attend the two-day orientation will register for classes at orientation. See similar questions...

If you have a large area to fill with sound or wish simply wish to have a loud stereo system you have to look for a speaker with both a high efficiency and high power handling. Our SS-15 has an efficiency of 88 db and maximum power capacity of 60 watts so the max sound level output is 108 db. But the ATS-5 efficiency is 93 db and the maximum power capacity is 200 watts so the max output is 120 db. See similar questions...

Warm edge" technology makes the glass window unit the strongest, longest lasting and most thermally efficient glass unit on the market today. The Intercept? process developed by PPG, is the most state-of-the-art insulated glass spacer system available, and is standard in all Alpine Window products. It is an insulated spacer system using a one-piece U-shaped channel to maintain consistent space between the two panes of glass. See similar questions...

Power efficiency is the percentage of maximum cutting force that can actually be utilized for work. Traditional shears (with a single moving jaw) typically have a power efficiency rating that averages 75%. This efficiency rating is attributed to the fact that cutting force actually decreases as much as 25% after the jaw reaches its maximum mechanical advantage. See similar questions...

The base rates for residential and small commercial customers of investor-owned utilities in Texas were frozen from September 1, 1999, to December 31, 2002. On January 1, 2002, rates for most of these customers were lowered, creating the "Price to Beat." The Affiliate Retail Electric Provider cannot charge above this rate until it loses 40 percent of its customers or five years pass, whichever comes first. See similar questions...

Home owners who have re-roofed with Rustic Shingle have found their energy costs to decrease by up to twenty percent after the roof was installed. This is due to Rustic Shingle's low emissivity value. Rather than pass the heat of the sun into your attic, Rustic Shingle reflects up to 94.5 percent of the sun's rays. This reflectiveness is an inherent property of the aluminum Rustic Shingle is composed of, regardless of the color you choose. See similar questions...

Arthritis and musculoskeletal pain can affect different people in different ways. Everyone gets aches and pains in their muscles and joints from time to time particularly if they take part in strenuous physical activities. Such pain is often short lived. However the different types of arthritis require medical assessment and intervention, the aim of which is to induce remission, relieve pain and improve function. See similar questions...
