Climate Consultant Analysis
- Winter months (December to February) show lower average temperatures with broader ranges, indicating colder weather with significant variations between highs and lows.
- Summer months (June to August) have higher average temperatures with narrower ranges, suggesting warmer weather with less variation between highs and lows.
- Spring (March to May) and fall (September to November) show transitional temperatures with moderate ranges.
HVAC Design Strategy
The building is in NYC near the Castle Clinton National Monument. From January to December, it is in the comfort zone for 8.0% of the time. Based on the analysis, the building needs 6.4% active cooling and 44.4% active heating, according to the data, the HVAC system for my building focuses on active heating by implementing windows on the west side to incorporate the heat from the sun.
HVAC Zones:
For the first three levels, I split the spaces into three zones: SW zone, NE zone, and the Center zone. I intend to design three sub-branchs of HVAC systems on each of these floors. This building have a mechanical room on each floor so I decided to use the decentralized air handling strategy, putting one air handler on each floor.
Floor 1 - 3 Zones:
SW Zone:
NE Zone:
Center Zone:
Floor 4 & 6 Zones:
SW Zone:
NE Zone:
Heating & Cooling Loads:
for some reason the specific return load all show 0 which I don't know why.
HVAC Systems:
Level 1
Level 2
Level 3
Level 4
Level 5 (This level is supporting level so does not have HVAC system)
Level 6

Design Challenges:
- for the 4th and 6th levels, there is a very limited space for me to put duct systems for two zones which will avoid any conflicts between the supply and return air systems and the floor opening. instead, I only put one circular system around the whole level for both HVAC zones.
- The specific supply/return loads analyzed and the actual loads are not quite matching. I need to do more analysis on the load of each of the air terminals and the duct sizes to make them match.
