Ventilation Strategies

The 3 basic ventilation strategies are –
  • Natural Ventilation
  • Spot Ventilation
  • Whole-house Ventilation

Natural Ventilation

The uncontrolled air movement through the cracks and small holes of a home is called Natural Ventilation. Previously, it was almost impossible to prevent the air pollutants entering through these holes. Modern technology has made it possible to effectively seal those holes and maintain an energy-efficient and less polluted environment inside a home. However, natural ventilation is necessary in a home and one can have that by opening windows and doors.
Many people also prefer to keep their home closed for natural ventilation points and use central heating and cooling throughout the year. Natural ventilation is unpredictable and uncontrollable. It is differently accepted to different people according to their choice and the climate.

Spot Ventilation

It is the method of removing indoor air pollution and/or moisture at its source to improve the effectiveness of natural and whole house ventilation. In this ventilation method, localized exhaust fans are used. The recommended intermittent or continuous ventilation rates for bathrooms of 50 or 20 cubic feet per minuteand kitchens of 100 or 25 cubic feet per minute, respectively.

Whole-House Ventilation

The objective behind whole-house ventilation is encouraged by the fact that natural ventilation and spot ventilation cannot provide adequate air quality. This ventilation system uses one or more fans and duct systems to exhaust stale air and/or supply fresh air to the house. Hence, it somehow provides controlled, uniform ventilation throughout a house.

Four Types of Ventilation Systems Are –

  • Exhaust Ventilation System: Depressurizes the building. Comparatively simple and inexpensive to install.
  • Supply Ventilation System: Pressurizes the building. It is also comparatively simple and installation is inexpensive.
  • Balanced Ventilation System: If the design is properly executed, it neither pressurizes nor depressurizes a house. Rather, approximately equal quantities of fresh outside air and polluted inside air are introduced and exhausted by them respectively.
  • Energy Recovery Ventilation System: Controlled ventilation is provided by them while minimizing energy loss. They transfer heat from warm inside air by exhausting it to the fresh but cold supply air. Hence, the costs of heating are reduced. In the summer, the warmer supply air is cooled by the inside air to reduce ventilation cooling costs.

Avoiding Heat Buildup

The best ways to keep your home cool during hot days are keeping the outdoor heat outside, avoiding heat-generating activities, and using spot ventilation.
Use light colors in your home to reflect heat. During hot days, keep the windows and doors closed to keep the outdoor heat outside and use shades to prevent the conduction of heat into your home.
Use microwave, cook on the stovetop, and use spot ventilation to avoid the heat of cooking. Also, cook outside to avoid the generation of heat inside your house.
Use spot ventilation of a bathroom fan to exhaust the heat of shower, washing clothes, etc.
Moreover, avoid any kind of heat generating activity such as running a computer, burning open flames, running a dishwasher, etc.
