Why is it essential to minimize the amount of ventilation in some cases?

Minimizing ventilation is often essential for controlling heating and cooling costs effectively. In certain situations, excess outdoor air can lead to increased energy consumption, as conditioned air (heated or cooled) can escape while unconditioned air enters the building. This can cause HVAC systems to work harder to maintain the desired indoor temperature, leading to higher energy bills and reduced efficiency. By carefully managing the amount of ventilation, professionals can ensure that indoor air quality is maintained while also keeping energy usage and costs in check.

Balancing outdoor noise pollution, maintaining aesthetics, and maximizing indoor humidity levels do not directly address the primary goal of energy efficiency in relation to heating and cooling costs. While those factors may be relevant in certain scenarios, minimizing ventilation mainly focuses on maintaining energy efficiency and comfort.
