Abstract
Heating, ventilation, and air conditioning systems ensure thermal comfort and indoor air quality safety. However, these systems account for 40–60% of the energy consumption of buildings. Therefore, it is imperative to reduce energy consumption to attain a national energy savings goal and reduce the carbon footprint. One of the most attractive options involves using passive solar systems. Such systems use solar energy naturally by applying conventional building elements to collect, store, and distribute solar energy. They have recently been rediscovered because they allow the rational use of solar radiation and can play an essential role in Nearly Zero Energy Buildings. This study proposes a solar air heater with sensible heat storage for preheating ventilation air. The proposed solution allows for capturing and accumulating solar energy during the day and releases it at night. The solar air heater has been developed and tested experimentally under laboratory conditions using a specially designed rig. Among other parameters, temperature distribution and power transferred from the wall to the supply ventilation air under different operating conditions have been analyzed. Results from experiments were used to assess the potential reduction in energy consumption in the selected examples of buildings using numerical calculations performed in ArCADia BIM software. Furthermore, Simply Payback Time, Net Present Value, and Profitability Index have been calculated to assess the economic premises of introducing the proposed solution. As was concluded, implementing solar air heaters can increase the energy performance of buildings.
