Questions:

1. Do you notice anything unusual or unexpected?

• High Heating Load in Meeting room (758 CFM) - As I have noticed, compared to other spaces, meeting room has a relatively high heating load. It would be interesting what causes this.
• High Cooling Load in Cafe (1387 CFM) - The highest cooling load is in the building is in the cafe.

2. Any challenges that you encountered in this supply duct routing exercise

Coordinating duct routing to match the building's zoning, especially when dealing with multiple zones on different floor levels, required careful planning. The challenge was to ensure that each zone received appropriate airflow without unnecessary complexity or inefficiency in the ductwork layout.

3. whether your proposed design meets the project’s spatial design goals

In developing the HVAC design, I aimed to meet the project's spatial design goals by ensuring minimum CFM requirements for each room, avoiding obstruction of floor openings, and confirming no intersections between structural and mechanical systems. By placing air diffusers 9 inches above the floor and ducts at 10 feet 6 inches, I've tried to balance the need for effective air distribution with the aesthetic and spatial integrity of the project. As I think, I made a mistake and not placed air diffusers for hallways on east spaces.

1. Any recommendations to make the design more sustainable (and lower the heating and cooling loads)

To enhance the sustainability of our HVAC design and further reduce heating and cooling loads, I recommend incorporating more energy-efficient materials and technologies. For instance, using high-performance insulation in walls and roofs can significantly minimize thermal transfer, reducing the need for heating and cooling. Additionally, the installation of energy-efficient windows and the strategic use of shading devices can mitigate solar heat gain, lowering cooling demands. Implementing a more sophisticated zoning system could also optimize energy use by allowing for more precise control over heating and cooling in different areas of the building, based on occupancy and time of day. These adjustments would not only contribute to a more sustainable design but also result in lower operational costs and a reduced environmental footprint.
