Ventilation is the key to a good indoor climate
Legislation places high demands on ventilation. Balance between supply air and extract air and efficient heat recovery contribute to achieving a good indoor climate without compromising the energy framework.
Our ventilation solutions are designed as decentralised or central residential ventilation. In recent years, decentralised residential ventilation has become widespread, which is partly due to the DS428 Danish fire standard and its stricter requirements for the ventilation solution.
Decentralised residential ventilation is characterised by one ventilation unit per dwelling. Central home ventilation is characterised by a common ventilation unit that ventilates several homes.
There are advantages and barriers to both decentralised and centralised residential ventilation, so you should consider the following in relation to your project.
Decentralized ventilation
Benefits
- Cheapest for smaller residential buildings (few homes)
- User influence (VAV) = satisfaction
- Decentralised payment of electricity
- Lower energy consumption (SFP), but increased power consumption for automation
- No need for VEX on roof or in technical room
Barriers
- Service is more expensive and more cumbersome
- The solution takes up living space
- De-icing and heating coil in home
- Expensive/difficult monitoring
- Noise from the system
- Outlet over roof
Central ventilation
Benefits
- Cheapest for larger residential buildings
- Easy service, both man-hours and materials
- No need for user intervention
- Easily monitored
- Central payment for electricity
- Known technology
Barriers
- Requires ventilation room
- “Higher” energy consumption
- VEX on the roof, rooftop house – price
- Individual VAV is more expensive
- Same temperature for all
- Smoke ventilation
EXHAUSTO LIVING system solutions
EXHAUSTO’s proposed solutions are examples that have been prepared to comply with current legislation. It must be emphasised that it is the responsibility of the project planner to ensure that the chosen solution complies with applicable legislation.
EXHAUSTO’s Living system solutions are divided into two main groups:
- EDV04 (EXHAUSTO decentralised residential ventilation)
- EBV04 (EXHAUSTO Central Home Ventilation).
Each solution consists of a functional description and an overview of the ventilation and fire protection products included in the solution.
