Passive strategies applied to optimize the energy efficient and adaptive comfort percent.
Add HVAC, temperature point, and schedule.
Roughly estimate the operational carbon of the building. Install PV panel on the roof and see whether it can cover the electricity use. In the end to check whether this building can be net zero.
Phase4: Conclusion
Heating degree day (HDD) setpoint: 10℃
Cooling degree day (CDD) setpoint: 18℃
From this image, the beneficial radiation is from east south side. and the harmful radiation is west north side.
Strong wind from west north.
Original Design: the big window is designed for beneficial radiation in long winter, and the shape is designed for the wind in winter. Besides, the stacked massing is for reduce the surface to volume ratio.
Rooms: For the restroom and janitor's closet, I put them to the solid side. And the 100-people assembly room, place it in the bottom, have the most sufficient sunlight.
Programs: 1st-Assembly Room with 100 people 2nd-Multipurpose Classroom with 30 people+Restroom 3rd-Individual Closed Office+Open Office with 2 people+Janitor's Closet.
People/Room: The ground floor room has the most high value in people/room. However, the most frequent used room located in the top level. Although the bottom one has the highest density by rarely used.
