The goal of this assignment, the first phase of the lab project that focuses on airflows and building ventilation, is to design, construct in model form, and test an enclosure (partial or full) for a typical balcony for a Chinese apartment. The motivation for this work is to propose feasible designs for Chinese residential buildings that are thermally comfortable and use a minimal amount of energy.

The third week of our airflow lab focuses on simulation:

1. Prepare to use the CONTAMW airflow simulation program, installed on two working computers in lab and available free to all with Windows computers. 
2. Become proficient in CONTAMW by completing the provided worksheet.
3. Use CONTAMW for the following investigation of your apartment-balcony, working at full (and not model) scale:

The fourth week of our airflow lab is in two phases: 

1. Please prepare an occupants’ manual for your Chinese apartment. Passively conditioned buildings require occupant involvement, much more than buildings with mechanical systems that ensure thermostat set points are maintained. Your apartment occupants can inhabit any of the rooms and can adjust the balcony openings and apartment windows and doors in a number of ways, for different wind and outdoor temperature conditions. 
2. Please consider the effect of airflow on the rate at which a miniature structure (even smaller than our elf houses) cools off. This is intended to combine thermal and airflow analysis.
