Ziqi YuanYour Design Journal entries for this module should highlight your design thinking and analysis results that influenced your decisions about:
- your overall HVAC system strategy
- your heating strategy and how you implemented it in your design
- your cooling strategy and how you implemented it
- any special HVAC system challenges that you encountered
Based on the New York location, both heating and cooling throughout the building are important. They are delivered through ducts. As the whole building exterior wall is using glass, they were chosen to have relatively good thermal resistance during passive design (triple glazing glass). With the large amount of airflow needed, the building is split into east and west parts, each has their own duct systems that go to the air handlers at the basement. The vertical ducts are large (48x48), thus they are put into the corner of the restrooms when possible. The ducts are sized to relatively represent the load requirements.
One thing I noted is that it is important to check the building types and the people number approcimation when setting up space schedule. It is also necessary to override shcematic (material) types when calculating heating and cooling loads in order to generate more accurate information. The routing of ducts was also challenging and needed careful planning as levels have different space configurations and aesthetic needs.
