Newbuild or upgrade installation? Need flexibility? Demanding energy requirements? Each project is unique and a great many factors determine the ideal ventilation system. However, the choice of residential ventilation system will essentially be based on three factors: comfort requirements, energy requirements and initial cost. This guide gives you the answers to all you need to know about ventilation in residential buildings.

ERV - Centralized Balanced Ventilation

In response to current requirements for energy performance in buildings, properties are becoming increasingly airtight, which means that stricter demands are made for ventilation in order to prevent damp and mould. Controlled balanced filtered ventilation is virtually a must today. The fact that it also greatly improves indoor comfort is, of course, only a plus. Today, ventilation systems are at least as important as your other property systems.

Some Advantages

  • Ensures a good indoor climate in all rooms all year round
  • Modern airtight homes should be served by controlled, balanced supply and extract air ventilation for occupant well-being
  • Reduces the risk of moisture damage to the building in the form of mold and fungus, or other adverse conditions, such as. condensation on the windows.
  • In homes ventilated only by an extract air system, there is no guarantee of achieving the required volume of fresh air in each room
  • Fine-mesh filtering keeps PM, pollen and exhaust gases out, creating a healthy indoor climate
  • With a demand-controlled unit installed to respond to humidity, CO2 or VOC levels, the unit auto-adapts to requirements
  • Helps reduce radon concentration.

WALL - ERV, Decentralized ventilation

Decentralized ventilation is described in different ways. We at Ventpro see it as a system with several small fan units that work together in a home without ventilation ducts.

During the 2000s, there has been a great development in decentralized ventilation. The ventilation units are placed / installed in the outer walls, each with an efficient fan, usually in combination with a ceramic heat exchanger. This heat exchanger works with so-called regenerative heat recovery. They draw in the outside air directly, filter it, heat or cool it, and then blow it out into specific locations.

As a rule, there is a ventilation unit in each room, but in larger rooms more than one may be needed. You simply install as many as needed to achieve the air exchange that is sufficient or required (at least one per room) depending on whether it is renovation or new construction. The principle is exactly the same, controlled supply and exhaust air flows with heat recovery, but completely without duct pipes.

Exhaust Ventilation with Fresh Wall Vents

Fresh air helps ensure that you and your family thrive. It is easy to improve the air circulation in your house by installing fresh air vents and intelligent exhaust fans. Thrive and feel good at home, in a healthy indoor environment.

Some Advantages

An inexpensive way to create an airflow in your home if compare to ERV solutions but this solution don’t have the advantage of energy recovery. We can also not control the amount of air but this solution is much better than nothing!

Install a intelligent fan in the bathroom, storageroom, laundryroom (polluted areas) and Fresh Wall Vents in bedroom and living areas.
