  2. Indoor air quality - Wikipedia

    en.wikipedia.org/wiki/Indoor_air_quality

    Humans are the main indoor source of carbon dioxide (CO 2) in most buildings. Indoor CO 2 levels are an indicator of the adequacy of outdoor air ventilation relative to indoor occupant density and metabolic activity. Indoor CO 2 levels above 500 ppm can lead to higher blood pressure and heart rate, and increased peripheral blood circulation. [85]

    New studies show that CO2 inside buildings could be just as harmful as outside.

  4. Illustrative model of greenhouse effect on climate change

    en.wikipedia.org/wiki/Illustrative_model_of...

    Absorption cross sections for CO2 (green) and water vapour (purple). The wavelengths most relevant to climate change are those where the green plot crosses the upper horizontal line, representing a CO2 level somewhat larger than the current concentration. CO 2 absorbs the ground's thermal radiation mainly at wavelengths between 13 and 17 micron ...

    English: This figure shows historical carbon dioxide (right axis) and reconstructed temperature (as a difference from the mean temperature for the last 100 years) records based on Antarctic ice cores, providing data for the last 800,000 years. This figure was produced by Leland McInnes using python and matplotlib and is licensed under the GFDL ...

  6. Household air pollution - Wikipedia

    en.wikipedia.org/wiki/Household_air_pollution

    For instance, electric stoves are cited as emission-free 'clean' alternatives to biomass at the household level. [ 30 ] However, negative externalities still exist – ambient air pollution in areas near power plants still poses a health risk, while the generation of electricity in India and China (countries largely dependent on coal for ...

  7. Carbon dioxide - Wikipedia

    en.wikipedia.org/wiki/Carbon_dioxide

    The symmetry of a carbon dioxide molecule is linear and centrosymmetric at its equilibrium geometry. The length of the carbon–oxygen bond in carbon dioxide is 116.3 pm, noticeably shorter than the roughly 140 pm length of a typical single C–O bond, and shorter than most other C–O multiply bonded functional groups such as carbonyls. [19]

  8. Ecohouse - Wikipedia

    en.wikipedia.org/wiki/Ecohouse

    An Eco-house could include some or all of the following: Higher than normal levels of thermal insulation; Better than normal air-tightness; Good level of daylight; Passive solar orientation — glazing oriented south for light and heat; Thermal mass to absorb that solar heat; Minimum north-facing glazing — to reduce heat loss
