Heating films are lightweight, typically 200 to 300 grams per square metre (0.061 lb/sq ft). Greenhouse gas emissions due to shipping will depend on distance travelled and transport method. Assuming the heating film travels a similar distance to other heating systems from manufacturer to installation, due to its comparatively low weight ...
Basically NHER measure the energy efficiency of dwellings as a function of energy cost per square meter. The energy usage is calculated by considering the all aspects of buildings (location, design, construction, water heating, cooking, ventilation and appliances, lighting etc.) and for dwelling energy rating it use some standard assumptions ...
There is a likelihood that underfloor heating may add to offgassing and sick building syndrome in an environment, particularly when the carpet is used as flooring. [citation needed] Electric underfloor heating systems cause low frequency magnetic fields (in the 50–60 Hz range), old 1-wire systems much more so than modern 2-wire systems.
A Deep Energy Retrofit (abbreviated as DER) is an energy conservation project in an existing building that leads to an overall improvement in building performance.While there is no exact definition for a deep energy retrofit, it can be characterized as a whole-building analysis and construction process that aims to reduce on-site energy use by 50% or more using existing technologies, materials ...
In the United States, a house built to passive house standard results in a building that requires space heating energy of 1 British thermal unit per square foot (11 kJ/m 2) per heating degree day, compared with about 5 to 15 BTU/sq ft (57 to 170 kJ/m 2) per heating degree day for a similar building built to meet the 2003 Model Energy Efficiency ...
Economically, electric heat can be compared to other sources of home heating by multiplying the local cost per kilowatt hour for electricity by the number of kilowatts the heater uses. E.g.: 1500-watt heater at 12 cents per kilowatt hour 1.5×12=18 cents per hour. [14]
