- Abstract
- A hybrid ventilation system including sewage heat recovery for low energy buildings has been
investigated using TRNSYS. Energy from solar collectors is used in combination with the heat
recovered from the sewage system to preheat the ventilation air and the cold water for domestic
use. Results show that the new system renders a possibility to use natural ventilation in passive
houses and zero energy buildings. The annual auxiliary energy need for the new system is lower
than for a conventional fan driven ventilation systems using air/air heat recovery units. Depending
on technical solution and site of installation, the system can provide free cooling during the
summer. Since... (More) - A hybrid ventilation system including sewage heat recovery for low energy buildings has been

standard mechanical ventilation systems. (Less)
