Design Journal Entry - Module 9

Your Design Journal entries for this module should highlight your design thinking and analysis results that influenced your decisions about:

• My location is in New York City which can get a large range in temperatures year round. However, the summer months are extremely hot, creating a larger demand for cooling loads. With this in mind, my design combines some ideas of passive design to reduce the load on the HVAC system. For example, there are large overhangs on the South Facade and minimal windows on the East and West Sides. These windows are also often connected to hallways rather than rooms so that the rooms do not overheat. The windows will also all be operable to allow the user to decide to let natural ventilation in. On the terms of winter months and provide heat, the large South facing windows will bring in lots of solar gain. Most components of the envelope also have a high R value to allow for more insulation. With these features in mind, I decided to go for a duct system to supplement extra heating and cooling when necessary. The mechanical room is on the sixth floor and all the ducts feed into it. The ducts run mainly along the corridors. The air terminals are along the walls that have windows as those will experience the most change in temperature. The largest difficulty I had was figuring out the sizing of the ducts. I tried to use the duct sizing tool however, I do not believe it worked correctly. I also had to figure out how to load in the Heating and Cooling Calculation tool into Revit as it did not appear in the 2025.2 update.
