Passive Heating and Cooling to Benefit HVAC

November 30, 2023

You may have heard the term "passive" when it comes to your heating or cooling needs, and may have been unsure exactly what it refers to. The concept of passive heating and cooling is an important one that's growing in popularity in recent years, and can often be very helpful for your HVAC system in terms of themes like costs, efficiency and more. 

At Thompson's Comfort Connection, while our primary services are found in the realm of active HVAC needs like AC and furnace repair or replacement, we're also here to help clients around Sandy, Draper and nearby areas with passive techniques that will help boost your system throughout the year. Here are some basics on what passive heating and cooling refer to, some of the key goals and benefits of passive approaches in addition to your active HVAC system, and a few common areas that are typically part of a passive approach.

Passive Vs. Active Heating and Cooling

When we talk about passive heating and cooling, we're referring to methods that do not require any external or mechanical energy sources. Instead, these methods rely on natural factors like sunlight, airflow and other elements of the home or building structure to help regulate temperature.

Active heating and cooling, on the other hand, refers to systems with active components like fans or motors. These parts are used to move air and alter temperature, and may require a power source.

As you've likely already surmised, however, these two systems aren't necessarily mutually exclusive. In fact, they're often used in concert for homeowners looking to achieve the best possible temperature regulation and comfort in their home.

Main Goals of Passive Heating and Cooling

The primary goal of passive heating and cooling methods is to reduce external energy usage and, therefore, costs related to HVAC needs. By using natural elements like sunlight or shade properly, you can work to maintain desired temperatures without the use of active systems. This will not only save you money, but it's also better for the environment.

But while reduced energy usage is a key goal, it's far from the only one. Passive heating and cooling can also improve overall air quality and reduce wear-and-tear on your active HVAC system, leading to longer lifespans and fewer repairs needed. Furthermore, passive heating and cooling can have a major impact on the electrical grid and sustainable energy efforts, helping to reduce strain on the systems and cut down on overall usage.

Common Passive Techniques

Some of the most common passive techniques used for heating and cooling include:

  • Insulation: Proper insulation helps prevent unwanted heat loss or gain in your home, resulting in more stable temperatures year-round. For instance, you may consider insulating your attic, walls or floors to maintain a comfortable temperature without the need for active heating or cooling.
  • Shading: By properly shading your home, you can reduce solar heat gain during warmer months and cut down on energy costs related to AC use. Trees, awnings and strategically placed windows are all great ways to achieve this.
  • Ventilation: Good ventilation is crucial for maintaining proper air flow and temperature regulation in your home. Properly designed ventilation can help cool a space without the use of AC, as well as provide natural ventilation for improved air quality.
  • Thermal Mass: This refers to materials like concrete or stone that have the ability to absorb and store heat, helping to regulate temperature by releasing it slowly over time. For instance, thermal mass materials can absorb heat during the day and release it at night, helping to maintain comfortable temperatures year-round.

Passive heating and cooling methods are becoming increasingly popular for their ability to improve energy efficiency, reduce costs, and improve overall comfort in your home. By combining these techniques with your active HVAC system, you can create a comprehensive and eco-friendly approach to heating and cooling.
