With six-pane glazing, a U g value as low as 0.24 W/(m 2 K) [R-value 24] was reported. [1] This brings several advantages, such as: Energy efficient buildings without modulated sun shading The desired overall window thermal transmittance value of lower than about 0.4 W/(m 2 K) is possible without having to depend on modulated external shading.
The term "low-energy house" is used in some countries for a specific type of building. [18] A low-energy house is a guideline rarely specified in actual values (heat load or space-heating minimum). A passive house is a standard, with specific recommendations to save heating energy.
Energy-efficient houses in cold climates often feature triple-glazed windows with a U-value between 0.19 and 0.26. In moderate and hot climates, quality double-glazed windows with a U-value of about 0.30 are generally a more cost-competitive and effective choice. [6]
In a sun-tempered building, the south-facing window area should be limited to about 5 to 7% of the total floor area, less in a sunny climate, to prevent overheating. Additional south-facing glazing can be included only if more thermal mass is added. Energy savings are modest with this system, and sun tempering is very low cost. [20]
Energy expenditures for low income households have risen over the past decades, and the energy burden (energy expenditures as share of household income) has increased since 1997. Mean residential energy expenditures increased by 27 percent from 2001 to 2005, to $1,522, and by almost 20 percent to $1,822 by fiscal year 2009.
Low-energy buildings, which include zero-energy buildings, passive houses and green buildings, may use any of a large number of techniques to lower energy use. Part of a series on Sustainable energy
