Which issue can arise from cold drafts in a room?

Cold drafts in a room can lead to low energy efficiency because they create areas of uneven temperature that cause heating systems to work harder to maintain a comfortable environment. When cold drafts enter a space, they can lower the local temperature, prompting heating systems to operate continuously or at higher capacities to compensate for the lost heat. This excessive demand can result in increased energy consumption, leading to higher utility bills and make it less efficient overall.

In contrast, options related to increased comfort, uniform temperature, and high indoor air quality are favorable outcomes that would not typically arise from the presence of cold drafts. In fact, drafts can cause discomfort, lead to temperature fluctuations, and potentially affect indoor air quality negatively by bringing in unconditioned air. Thus, the connection between cold drafts and energy efficiency is clear, reinforcing the idea that neglecting this issue can lead to inefficiencies in heating and consequently higher energy costs.
