Weatherization
Weatherization (American English) or weatherproofing (British English) is the practice of protecting a building and its interior from the elements, particularly from sunlight, precipitation, and wind, and of modifying a building to reduce energy consumption and optimize energy efficiency. Weatherization is distinct from building insulation, although building insulation requires weatherization for proper functioning. Many types of insulation can be thought of as weatherization, because they block drafts or protect from cold winds. Whereas insulation primarily reduces ''conductive'' heat flow, weatherization primarily reduces ''convective'' heat flow. In the United States, buildings use one third of all energy consumed and two thirds of all electricity. Due to the high energy usage, they are a major source of the pollution that causes urban air quality problems and pollutants that contribute to climate change. Building energy usage accounts for 49 percent of sulfur dioxide e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Office Of Energy Efficiency And Renewable Energy
The Office of Energy Efficiency and Renewable Energy (EERE) is an office within the United States Department of Energy. Formed from other energy agencies after the 1973 energy crisis, EERE is led by the Assistant Secretary of Energy Efficiency and Renewable Energy (Assistant Secretary), who is appointed by the president of the United States and confirmed by the U.S. Senate. Alejandro Moreno currently leads the office as the Acting Assistant Secretary.

It has foundations in the former agencies Federal Energy Administration, the Energy Research an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
American English
American English, sometimes called United States English or U.S. English, is the set of variety (linguistics), varieties of the English language native to the United States. English is the Languages of the United States, most widely spoken language in the United States and, since 2025, the official language of the United States. It is also an official language in 32 of the 50 U.S. states and the ''de facto'' common language used in government, education, and commerce in all 50 states, the District of Columbia, and in all territories except Puerto Rico. Since the late 20th century, American English has become the most influential form of English worldwide. Varieties of American English include many patterns of pronunciation, vocabulary, grammar, and particularly spelling that are unified nationwide but distinct from other forms of English around the world. Any North American English, American or Canadian accent perceived as lacking noticeably local, ethnic, or cultural markedness ...

Building Insulation
Building insulation is material used in a building (specifically the building envelope) to reduce the flow of thermal energy. While the majority of insulation in buildings is for thermal insulation, thermal purposes, the term also applies to acoustic insulation, Fireproofing, fire insulation, and Cushioning, impact insulation (e.g. for vibrations caused by industrial applications). Often an Building insulation materials, insulation material will be chosen for its ability to perform several of these functions at once. Since prehistoric times, humans have created thermal insulation with materials such as animal fur and plants. With the agricultural development, earth, stone, and cave shelters arose. In the 19th century, people started to produce insulated panels and other artificial materials. Now, insulation is divided into two main categories: bulk insulation and reflective insulation. Buildings typically use a combination. Insulation is an important economic and environmenta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Infiltration (HVAC)
Infiltration is the unintentional or accidental introduction of outside air into a building, typically through cracks in the building envelope and through use of doors for passage. Infiltration is sometimes called air leakage. The leakage of room air out of a building, intentionally or not, is called exfiltration. Infiltration is caused by wind, negative pressurization of the building, and by air buoyancy forces known commonly as the stack effect. Infiltration measures The infiltration rate is the volumetric flow rate of outside air into a building, typically in cubic feet per minute (CFM) or liters per second (LPS). The air exchange rate, (''I''), is the number of interior volume air changes that occur per hour, and has units of 1/h. The air exchange rate is also known as air changes per hour (''ACH''). ACH is the hourly ventilation rate, divided by the building volume. It can be calculated by multiplying the building's CFM by 60, and then dividing by the building volume. ...

Storm Windows
''Storm Windows'' is the seventh album by American folk singer and songwriter John Prine, released in 1980. It was his last release on a major label; he joined Al Bunetta and Dan Einstein to form Oh Boy Records, on which all his subsequent recordings were released. Recording After receiving some of the worst reviews of his career for the 1979 party album ''Pink Cadillac'', Prine moved towards a more country-flavored sound on ''Storm Windows'' which foreshadowed much of his work in Nashville in the 1980s. The album was produced by Barry Beckett, who had previously worked with Paul Simon and Bob Dylan, and was recorded at the legendary Muscle Shoals Sound Studios in Sheffield, Alabama. Critics liked it far more than Prine's previous release but, as David Fricke observed in 1993, many listeners might be surprised to learn that "half of the songs that ended up on that album were first tried out during those madhouse '' Pink Cadillac'' sessions." The album was a return to a rel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Storm Door
A storm door is a type of door that is installed in front of an exterior access door to protect it from bad weather and allow ventilation. Storm doors generally have interchangeable glass panels and window screen panels to provide visibility and prevent flying insects from entering the home. Construction Storm doors are typically made from wood, aluminum and plastics such as vinyl (PVC) and fiberglass. There are three basic types of storm doors: full-view, retractable screen, and ventilating. Full-view storm doors typically include a full glass panel and most an interchangeable full screen. Retractable screen storm doors feature a screen that is rolled up into the frame of the storm door when not in use, and can be removed entirely. Wood Wood was the original material from which storm doors were made. While wooden screen doors can be visually the most appealing, the wood itself requires painting or some other form of coating to protect it from the weather. Wooden screen doo ...

Light Tube
Light tubes (also known as solar pipes, tubular skylights or sun tunnels) are structures that transmit or distribute natural or artificial light for the purpose of illumination and are examples of optical waveguides. In their application to daylighting, they are also often called tubular daylighting devices, sun pipes, sun scopes, or daylight pipes. They can be divided into two broad categories: hollow structures that contain the light with reflective surfaces; and transparent solids that contain the light by total internal reflection. Principles of nonimaging optics govern the flow of light through them. Types IR light tubes Manufacturing custom designed infrared light pipes, hollow waveguides and homogenizers is non-trivial. This is because these are tubes lined with a highly polished infrared reflective coating of gold, which can be applied thick enough to permit these tubes to be used in highly corrosive atmospheres. Carbon black can be applied to certain parts of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flashing (weatherproofing)
Flashing is thin pieces of impervious material installed to prevent the passage of water into a structure from a joint or as part of a weather resistant barrier system. In modern buildings, flashing is intended to decrease water penetration at objects such as chimneys, vent pipes, walls, windows and door openings to make buildings more durable and to reduce indoor Mold (fungus), mold problems. Metal flashing materials include lead, aluminium, copper, stainless steel, Zinc, zinc alloy, and other materials. Etymology and related terms The origin of the term ''flash'' and ''flashing'' are uncertain, but may come from the Middle English verb ''flasshen'', 'to sprinkle, splash', related to ''flask''. ''Counter-flashing'' (or ''cover flashing'', ''cap flashing'') is a term used when there are two parallel pieces of flashing employed together such as on a chimney, where the counter-flashing is built into the chimney and overlaps a replaceable piece of ''base flashing''.

Siding (construction)
Siding or wall cladding is the protective material attached to the exterior side of a wall of a house or other building. Along with the roof, it forms the first line of defense against the elements, most importantly sun, rain/snow, heat and cold, thus creating a stable, more comfortable environment on the interior side. The siding material and style also can enhance or detract from the building's beauty. There is a wide and expanding variety of materials to side with, both natural and artificial, each with its own benefits and drawbacks. Masonry walls as such do not require siding, but any wall can be sided. Walls that are internally framed, whether with wood, or steel I-beams, however, must always be sided. Most siding consists of pieces of weather-resistant material that are smaller than the wall they cover, to allow for expansion and contraction of the materials due to moisture and temperature changes. There are various styles of joining the pieces, from board and batton, wher ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Housewrap
Housewrap (or house wrap), also known by the genericized trademark homewrap (or home wrap), generally denotes a modern synthetic material used to protect buildings. Housewrap functions as a water-resistant layer, preventing rain or snow from getting into the wall assembly while allowing water vapor to pass to the exterior. It is NOT a weather resistant layer, as weather elements include sun, and housewraps can only be exposed for a few months before being damaged, and temperature, and housewraps do not insulate. If moisture from either direction is allowed to build up within stud or cavity walls, mold and rot can set in and fiberglass or cellulose insulation will lose its R-value because of the heat-conducting moisture. House wrap may also serve as an air barrier if it is sealed carefully at seams and supported to resist wind loads. Housewrap is a replacement for the older tar paper or asphalt saturated felt on walls. It is lighter in weight, available in much wider rolls, ...
