Natural ventilation takes advantage of airflow and wind pressure to regulate and cool indoor spaces. This method replenishes fresh air inside and reduces indoor air pollution. Ventilating naturally is also cost-effective and energy-efficient. To achieve optimum ventilation, it’s critical to employ a building design that maximises the pressure difference between indoor and outdoor environments. Most of the time, we achieve this type of ventilation system by manually opening and closing windows. Although true for most buildings, nowadays it’s possible to automate openings by using electric window openers. An automated system is also more secure and convenient for occupants, especially if it’s a large office or commercial building.
Automated natural ventilation: the benefits
One of the many reasons why architects and builders hesitate to incorporate natural ventilation in building design is convenience. It’s indeed inconvenient for large buildings if occupants need to operate manual window openers from time to time. The same is also true for commercial spaces. This technique may work for residences and small structures, but not for spaces meant for a large number of occupants.
Automation is the best solution that will make natural ventilation operation easier for occupants and building managers. Automated window openers are the hassle-free way of controlling and maintaining indoor air quality and temperature. Most importantly, you can allow fresh air in without bothering the occupants busy with their daily tasks.
Of course, automated window control systems also include different features and designs. The right system depends on the needs of the buildings and their occupants. It’s also critical to consider installation and maintenance. In the case of retrofits and additions, it’s best to determine how long the process will take without disrupting everyday operations.
A smart way to control natural ventilation
One of the most significant challenges designers face with natural ventilation is its unpredictability. Since you are relying on environmental factors, it can change at any time of the day. That’s why incorporating the right technique is crucial to achieving maximum indoor comfort with natural ventilation. How does automation resolve this concern?
Automated natural ventilation isn’t only about electronic openers for windows and openings. Nowadays, you can have a sophisticated system installed with sensors that monitor the indoor and outdoor conditions. For example, a sensor will log outdoor data such as wind pressure, temperature, and humidity. At the same time, another sensor gathers the same information indoors. The data collected by these sensors will signal when the windows will open and for how long.
Security is another issue with natural ventilation. If one of the windows gets left open at the end of the day, it could compromise the building’s integrity. With automated natural ventilation, you can ensure that all the openings are closed as the last occupant leaves the building at the end of the day.
Indeed, natural ventilation has many benefits to consider, but also has its share of challenges. And to maximise these benefits while overcoming the known concerns, the best solution is to incorporate automation in the natural ventilation design.
