- Strategy and implementation of HVAC systems
I analyzed my building energy load with two main zones, North and South, for each level because my design has public spaces such as exhibition rooms, conference rooms, seminar rooms in the northern part of the building and, on the other hand, office spaces in the southern part, so that it can be assumed that the operation time of each part can be different. According to the Loads Reports, the peak loads for both cooling and heating in the north area of the building is quite higher than those in the south area. I think that this is mainly because north part includes larger spaces than south one and north part requires more heating energy in winters as well. Based on the result, I calculated the necessary CFMs for rooms and placed HVAC systems to satisfy the CFMs.
For the North area, one air handler is placed on the level two floor and controls all air supplement for each level to maximize the efficiency. In addition, zone controllers are installed in each main rooms such as exhibition rooms and conference rooms to facilitate individual adjustments of the room temperatures.
In the southern part of the building, one air handler is settled at each level because it is mainly used the operation staffs as back offices, thereby it is better to have flexibility of the active air conditioning systems, so user can adjust the temperature just in the specific areas.
- Challenges of modeling HVAC systems
It was difficult to understand connections of each component only with floor plans and section views. After merging it with the architecture model and the structural model in ACC coordination view, I realized some mistakes of modeling, for instance, a flexible duct was connected to a bottom side, not an upper side. In addition, it has a lot of trouble to coordinate and connect a vertical duct and a horizontal duct in a proper way.
