A number of homes and small apartment buildings have demonstrated combining a large internal water tank for heat storage with roof-mounted solar-thermal collectors. Storage temperatures of 90 °C (194 °F) are sufficient to supply both domestic hot water and space heating. The first such house was MIT Solar House #1, in 1939.
Ideal thermostat setting for summer. Just as 68 degrees F is considered the best temperature for a house in winter, experts call 78 degrees F the magic number for the summer months. This interior ...
Thermal comfort is the condition of mind that expresses subjective satisfaction with the thermal environment. [ 1] The human body can be viewed as a heat engine where food is the input energy. The human body will release excess heat into the environment, so the body can continue to operate. The heat transfer is proportional to temperature ...
According to the 2020 N.C. Climate Science Report, most parts of the Tar Heel State are projected to see at least two to three additional weeks of very hot days − maximum temperature of 95 ...
For example, a conventional heat pump system used to heat a building in Montana's −57 °C (−70 °F) low temperature or cool a building in the highest temperature ever recorded in the US—57 °C (134 °F) in Death Valley, California, in 1913 would require a large amount of energy due to the extreme difference between inside and outside air ...
A well-designed overhang may be all that is necessary to shade the glazing in the summer. The temperature variations caused by the heat losses and gains can be moderated by thermal mass and low-emissivity windows. Thermal mass can include a masonry floor, a masonry wall bordering the house, or water containers.
Geothermal heating is the direct use of geothermal energy for some heating applications. Humans have taken advantage of geothermal heat this way since the Paleolithic era. Approximately seventy countries made direct use of a total of 270 PJ of geothermal heating in 2004. As of 2007, 28 GW of geothermal heating capacity is installed around the ...
Anoxic waters are areas of sea water, fresh water, or groundwater that are depleted of dissolved oxygen. The US Geological Survey defines anoxic groundwater as those with dissolved oxygen concentration of less than 0.5 milligrams per litre. [ 1] Anoxic waters can be contrasted with hypoxic waters, which are low (but not lacking) in dissolved ...
