There are three basic ventilation strategies: natural ventilation, spot ventilation, and whole-house ventilation.  **Natural ventilation** is the uncontrolled air movement in and out of the cracks and small holes in a home. In the past, this air leakage usually diluted air pollutants enough to maintain adequate indoor air quality. Today, those cracks and holes are sealed to make our homes more energy-efficient, and after a home is properly air sealed, ventilation is necessary to maintain a healthy and comfortable indoor environment. Opening windows and doors also provides natural ventilation, but many people keep their homes closed up because they use central heating and cooling systems year-round. Natural ventilation is unpredictable and uncontrollable and depends on a home's airtightness, outdoor temperatures, wind, and other factors.   **Spot ventilation** can improve the effectiveness of natural and whole-house ventilation by removing indoor air pollution and/or moisture at its source. Spot ventilation includes the use of localized exhaust fans, such as those used above kitchen ranges and in bathrooms.  **W****hole-house ventilation** use is typically motivated by concerns that natural ventilation won't provide adequate air quality, even with source control by spot ventilation. Whole-house ventilation systems provide controlled, uniform ventilation throughout a house. These systems use one or more fans and duct systems to exhaust stale air and/or supply fresh air to the house.  *Photo caption: Have your ductwork cleaned every 3-5 years to remove dust, allergens, mildew, mold spores and contaminants.* *Source: Energy.gov*  ### Current Articles ### Recent Issues - [November 2019 (23)](https://blog.citizensenergygroup.com/engauge/archive/2019/11) - [November 2018 (21)](https://blog.citizensenergygroup.com/engauge/archive/2018/11) - [January 2021 (21)](https://blog.citizensenergygroup.com/engauge/archive/2021/01) - [October 2021 (21)](https://blog.citizensenergygroup.com/engauge/archive/2021/10) - [February 2020 (20)](https://blog.citizensenergygroup.com/engauge/archive/2020/02) - [December 2021 (20)](https://blog.citizensenergygroup.com/engauge/archive/2021/12) - [October 2018 (19)](https://blog.citizensenergygroup.com/engauge/archive/2018/10) - [January 2019 (19)](https://blog.citizensenergygroup.com/engauge/archive/2019/01) - [June 2020 (19)](https://blog.citizensenergygroup.com/engauge/archive/2020/06) - [August 2019 (18)](https://blog.citizensenergygroup.com/engauge/archive/2019/08) - [October 2019 (18)](https://blog.citizensenergygroup.com/engauge/archive/2019/10) - [April 2020 (18)](https://blog.citizensenergygroup.com/engauge/archive/2020/04) - [September 2022 (18)](https://blog.citizensenergygroup.com/engauge/archive/2022/09) - [July 2019 (17)](https://blog.citizensenergygroup.com/engauge/archive/2019/07) - [July 2020 (17)](https://blog.citizensenergygroup.com/engauge/archive/2020/07) - [June 2021 (17)](https://blog.citizensenergygroup.com/engauge/archive/2021/06) - [April 2019 (16)](https://blog.citizensenergygroup.com/engauge/archive/2019/04) - [January 2020 (16)](https://blog.citizensenergygroup.com/engauge/archive/2020/01) - [October 2020 (16)](https://blog.citizensenergygroup.com/engauge/archive/2020/10) - [December 2020 (16)](https://blog.citizensenergygroup.com/engauge/archive/2020/12) - [April 2021 (16)](https://blog.citizensenergygroup.com/engauge/archive/2021/04) - [July 2021 (16)](https://blog.citizensenergygroup.com/engauge/archive/2021/07) - [September 2020 (15)](https://blog.citizensenergygroup.com/engauge/archive/2020/09) - [March 2021 (15)](https://blog.citizensenergygroup.com/engauge/archive/2021/03) - [June 2022 (15)](https://blog.citizensenergygroup.com/engauge/archive/2022/06) - [February 2019 (14)](https://blog.citizensenergygroup.com/engauge/archive/2019/02) - [May 2019 (14)](https://blog.citizensenergygroup.com/engauge/archive/2019/05) - [May 2022 (14)](https://blog.citizensenergygroup.com/engauge/archive/2022/05) - [July 2022 (14)](https://blog.citizensenergygroup.com/engauge/archive/2022/07) - [October 2023 (13)](https://blog.citizensenergygroup.com/engauge/archive/2023/10) - [September 2021 (12)](https://blog.citizensenergygroup.com/engauge/archive/2021/09) - [March 2023 (12)](https://blog.citizensenergygroup.com/engauge/archive/2023/03) - [May 2023 (12)](https://blog.citizensenergygroup.com/engauge/archive/2023/05) - [June 2023 (12)](https://blog.citizensenergygroup.com/engauge/archive/2023/06) - [February 2022 (11)](https://blog.citizensenergygroup.com/engauge/archive/2022/02) - [August 2018 (10)](https://blog.citizensenergygroup.com/engauge/archive/2018/08) - [August 2023 (10)](https://blog.citizensenergygroup.com/engauge/archive/2023/08) - [March 2022 (9)](https://blog.citizensenergygroup.com/engauge/archive/2022/03) [![PDF Archives](https://no-cache.hubspot.com/cta/default/2545024/33b9e93c-8f43-4101-9b48-7e78154731f5.png)](https://cta-redirect.hubspot.com/cta/redirect/2545024/33b9e93c-8f43-4101-9b48-7e78154731f5) **Engauge** is published by Citizens Energy Group, Corporate Affairs Department, under the direction of Shannon Stahley, Director of Corporate and Public Affairs.
