Brenda's Top Business Tips

The world of business is interesting but it can also be very difficult to understand, particularly if you are just starting out. When I was just starting out, I was super confused by what I saw and heard. Thankfully, I had some friends who were experienced business managers. They gave me lots of fantastic advice and guidance as I prepared to start my new business. I have yet to start my new business venture but I now feel confident enough to share what I have learnt about business development. I hope you like this blog and that it helps you navigate the world of business.

Home Ventilation: Techniques and Technologies

Rene Elliott

Proper home ventilation plays a crucial role in maintaining a healthy and comfortable indoor environment. Ensuring the exchange of stale air with fresh air helps remove pollutants, control humidity levels and prevent the buildup of harmful substances. Below, learn about some effective techniques and innovative technologies used by home ventilation contractors.

Natural Ventilation

Natural ventilation is the oldest and simplest form of home ventilation. It leverages natural forces like wind and temperature differences to create airflow. Here are a few techniques commonly employed:

Cross Ventilation

This technique involves opening windows and doors strategically to allow fresh air to flow around the entire house. By creating an inlet and an outlet, cross ventilation effectively circulates fresh air.

Stack Effect

By utilising the principle that warm air rises, the stack effect involves positioning openings high and low in a home. This allows hot air to escape through the upper openings while drawing in cooler air through the lower ones.

Mechanical Ventilation

Mechanical ventilation systems are designed to actively remove old stale air, replacing it with fresh air. They offer precise control over air exchange rates and are suitable for tightly sealed homes. Here are two common mechanical ventilation techniques:

Exhaust Ventilation

This method utilises exhaust fans in specific areas such as kitchens and bathrooms. These fans expel stale air from the house, creating negative pressure that draws in fresh air from outside through gaps and cracks.

Supply Ventilation

Supply ventilation systems work by introducing fresh air into the home through ducts and vents. The stale air is simultaneously expelled, ensuring a constant flow of fresh air. Energy-efficient systems often incorporate heat recovery mechanisms to minimise energy loss.

Innovative Technologies

Modern technology provides innovative home ventilation solutions. Here are a few cutting-edge technologies employed by ventilation experts:

Heat Recovery Ventilation (HRV)

HRV systems recover the heat from the outgoing stale air and use it to preheat the incoming fresh air. This process significantly reduces energy consumption while maintaining a comfortable indoor temperature.

Demand-Controlled Ventilation (DCV)

DCV systems monitor and adjust ventilation rates based on the occupancy and air quality in different areas of the home. By dynamically responding to changing conditions, these systems optimise energy efficiency while ensuring adequate ventilation.


Home ventilation is vital for maintaining a healthy indoor environment. Whether you opt for natural ventilation techniques or invest in mechanical systems, it's crucial to consult with professional home ventilation contractors to determine the most suitable solution for your specific needs.
