Better air for a healthier and drier Home!
If you currently are buying or building a house, we know how exciting (and stressful) this time is for you!
There are so many things to consider … bench surfaces, appliances, wall colours, tile, carpet … the list goes on. Chances are, your top priority is to create a healthy environment for your family.
Recently, there has been an increased focus on homes, old and new, being well insulated and airtight in order to increase energy savings and – more importantly – protect against asthma and other respiratory illnesses.
But are well-insulated, airtight homes enough to satisfy today’s discerning homebuyer?
In addition to good insulation it is vital for homes to be well ventilated. This prevents excess moisture from building up. Showers, un-flued gas heaters, cooking and even breathing create moisture and dampness. Condensation is the visible symptom of unhealthy air in homes.
Kiwi climate, often cold and wet in winter, make it impractical to open doors and windows all year long. This is where a Home Ventilation System can help!
So … what does a home ventilation system actually do and why would I include one in my new build?
You would be surprised by the amount of moisture a new home can produce. Concrete slabs contain several thousand litres of water and can take an average of one month per 25mm of slab thickness to dry completely.
Home ventilation systems use fans to move air into the house, providing continuous ventilation regardless of the weather. This helps to maintain air quality and remove moisture from everyday living activities. Well designed and installed home ventilation system deliver required air replacement continuously and independently of weather conditions.
Massey University research shows that home ventilation systems reduce fungal spores, moisture and carbon dioxide, making a home drier and healthier. Occupants experience fewer headaches, sneezing and eye irritations. Drier homes can also be heated more effectively and are more durably.
There are two types of home ventilation system to consider:
- Positive pressure ventilation systems. These systems draw fresher, drier air into the home from either the roof cavity or outside. This air is then passed through a high efficiency filter and introduced into the home. This introduced air forces out the moist, stale air that causes condensation, mould and mildew.
- Balanced pressure/energy exchanger ventilation systems. These systems use the energy the household has paid for, say to heat from the lounge, and pass it through an advanced energy recovery converter. It then tempers the fresh, dry air from outside before moving it to rooms that need it most.
Which system is best for your Home?
It depends on many factors such as the design of your house, its floor area, the type of roof and the local climate. Each house is different so send us your plans to request a design, or Book a Free Home Assessment to know what system suits you most.
