COMPLETE QUESTION:

Why might better-insulated buildings make air pollution more of a problem?

ANSWER: It prevents the passage of waste gases out of the building and inflow of fresh air which can leads to health related issues.

EXPLANATION:

Building insulation reduces the heat surplus in warmer weather condition and reduces the heat loss during cold weather condition.

The negativity that comes with insulating a building is an increased air pollution. In the process of preventing heat loss to the environment by insulating a building, there's a resultant reduction or sometimes blocking of air flow inside the building. This will cause the concentration of waste that are in gas form inside the building, emanated from human activities like cooking (fuel burning), respiration, and other activities.

Overtime, this trapped in of waste gases can leads to sick building syndrome (an health related issue).
