A breath of fresh air for your indoor climate, the environment and your wallet
If you’re wanting to make your building as green as possible, consider installing a passive ventilation system. You’ll not only save thousands each year, but you’ll improve the quality of your internal climate whilst doing your bit for the environment too.
Passive ventilation is a natural ventilation system that makes use of natural forces, such as wind and thermal buoyancy, to circulate air to and from an indoor space. These ventilation systems work to regulate the internal air temperature as well as bring fresh air in and send stale air out. This is largely achieved through the opening and closing of windows and vents which act as a source of air as well as an exhaust.
Passive ventilation systems work in a number of ways including:
Wind-driven ventilation – arising from different pressures created by winds around a building
Buoyancy-driven ventilation – created by forces resulting from the temperature difference between the interior and exterior of a building
Night Cooling - a passive cooling method, driven by the natural driving forces of the wind and/or thermally (stack) generated pressures. The heat absorbed by a building's exposed thermal mass during the day is released to the indoor air at night, after which it is purged by night ventilation. Meanwhile, external fresh air cools down the thermal mass which then acts as a heat sink during the following day. The night purge involves automatically operable windows or louvres being opened for a pre-set period of time over night, allowing a natural air flow through the building.
There are a number of benefits to passive ventilation, including:
Reduced costs. As passive ventilation systems rely on natural forces, you’ll save significantly on your building’s energy consumption and therefore save significantly on your energy bills.
Low maintenance. Passive ventilation systems do not require costly maintenance, further reducing costs as well as saving you time and effort.
Cleaner air. Passive ventilation systems ensure that clean air is flowing throughout your building at all times. This will improve your air quality which, in turn, will improve the health of the occupants of the building and increase productivity and concentration levels.
Passive ventilation is incredibly versatile. If you’re operating in an established building, there are a number of things we can do to add a passive ventilation system to the systems you already have in place. The new passive system will complement your existing system to ensure you still reap the rewards of utilising natural forces.
If you’re building a new building from scratch, we can advise on the best options for a passive ventilation system.
Almost all buildings can make use of passive ventilation systems including office buildings, schools, theatres, and hospitals.
Examples of buildings with passive ventilation
We are professional passive ventilation consultants and suppliers. We can help you install a system in an existing structure or plan your passive system in a new build. We’ll work closely with you to find the best passive ventilation system that suits your needs. We’ve worked on a broad range of projects, implementing passive ventilation systems for various buildings including apartment complexes, office buildings, schools and hospitals.
