Submission detail: This graphic attempts to portray the impact of integrating Natural Ventilation on the Annual HVAC Energy Usage and the Thermal Comfort of the occupants. It starts with portraying the Window Opening Factor and its impact on the ACH. In the model, we can observe the windows opening when • Tzone air > TSet point • Tzone air > Toutside air • Availability Schedule Value = 1 Window opening aids in removing the accumulated heat from the previous day and hence helps in maintaining the internal Set temperatures.

What our judges like about this submission
The graphics indicate nicely the benefits of natural ventilation on annual energy savings and comfort. While natural ventilation study often assumes open floor plates, it is refreshing to see the 5 zones model, and the benefits of the zones. The “dial” displays on performance are easy to read. The 8760 hours display clearly indicates the “hot” spot where natural ventilation is possible. – Luke Leung
The carpet graph is an excellent way to show window opening conditions and energy consumption for each hour throughout the year, it is simple but conveys enough information and is very easy to follow. The dashboard on the right is a great addition to the carpet graph and provides the readers with key take-aways. – Rufei Wang
