Please refer to the article Halmak Rebornįor the more detailed breakdown of the results.Īll scripts are opensourced and can be verified in the Designed with the modern, web based English in mindĭuring the research I've identified the following results: in terms of efficiency.Highly symmetrical design that accounts for individual fingers strength.Very low overall horizontal hands movement.Very low same finger / same hand usage overheads.Very low overall fingers movement distance.Nearly maximal possible typing efficiency.Build based on the real world hand movements analysis.More details and a documented process can be found on Like awning windows, they generally have lower air leakage rates than sliding windows because the sash closes by pressing against the frame.This is an AI designed keyboard layout that was built within the These sliding windows generally have higher air leakage rates than projecting or hinged windows. Only the bottom sash slides upward in a single-hung window. Single- and double-hung. Both sashes slide vertically in a double-hung window.When installed properly they're airtight but are not suitable in places where window ventilation and egress is desired. Like single- and double-hung windows, they generally have higher air leakage rates than projecting or hinged windows. Only one sash slides in a single-sliding window. Single- and double-sliding. Both sashes slide horizontally in a double-sliding window.Like both awning and casement, they generally have lower air leakage rates because the sash closes by pressing against the frame. Hopper. Hinged at the bottom and open inward.Because the sash closes by pressing against the frame, they generally have lower air leakage rates than sliding windows. Awning. Hinged at the top and open outward.Air leakage rates will vary with the type and quality of the weatherstripping and seals, and will generally increase over time due to operational use. See the Efficient Windows Collaborative for more information on the different spacer types.Īnother important consideration is how the windows operate. Since all operable windows may have undesired air leakage which will decrease your home's energy efficiency, the choice of operator type can impact overall energy use. Look for "warm edge" spacers which are designed to lower the window U-factor and reduce condensation at the edge of the window. In addition, they provide accommodation for thermal expansion and pressure differences, while also preventing moisture and gas leaks.Ī variety of spacers are available with different impacts on the window U-factor. Spacers with associated sealants are used to keep the layers of glazing the correct distance apart. It has better thermal performance than argon but is also more costly. Krypton can be used when the space in thinner than usual - usually about ¼ inch. In order to minimize heat transfer between the interior and exterior of the window, the space between glazing layers, usually about 1/2", is filled with argon or krypton gas both are inert, non-toxic, clear, and odorless.Īrgon is most commonly used because it is inexpensive and performs well in the typical 1/2" space. These films are inexpensive compared to total window replacements, last 10 to 15 years without peeling, save energy, reduce fabric fading, and increase comfort. Different types of low-e coatings have been designed to allow for high solar gain, moderate solar gain, or low solar gain, and and they can also be tuned to control the amount of visible daylight transmitted.Īlthough low-e coatings are usually applied during manufacturing, some are available for do-it-yourselfers. The low-e coating lowers the U-factor of the window, and can manage the daylight transmittance as well as the solar heat gain through the glazing system. Windows manufactured with low-e coatings typically cost about 10% to 15% more than regular windows, but they reduce energy loss by as much as 30% to 50%.Ī low-e coating is a microscopically thin, virtually invisible, metal or metallic oxide layer deposited directly on the surface of one or more of the panes of glass. Low-emissivity (low-e) coatings on glass control heat transfer within the insulated glazing.
