How Do Seasonal Changes Affect Building Health?


Author: Alex Falck –

As we transition from dry, cool winter months to hot, humid summer months, you may be saying to yourself, “Woohoo! Bring on the heat!” However, seasonal changes can affect building health. Specifically, the summer season can present major problems for facility managers and building owners as their buildings’ HVAC systems struggle to keep up with increasing cooling loads and extremely humid outdoor air.

Just as spring plant life sprouts, HVAC mechanical issues can pop up with warmer temperatures. Poor indoor conditions such as high indoor relative humidity, negative building pressure, CO2 buildup, or drastic temperature fluctuations are just a few examples.

Staying ahead of these issues before they become noticeable, costly problems is crucial when considering the overall health of your building and its HVAC systems.

Humidity: A Common Seasonal Issue

At various facilities, a common issue that comes with changing seasons is humidity. Specifically, humidity can be difficult to maintain at a comfortable level.

In the winter, the heating mode on air handling equipment can heat or evaporate the existing moisture in the air to reduce the overall relative humidity as outdoor air is brought into the building. However, in the summer, the opposite occurs: the air handling equipment cools the building space and doesn’t heat or evaporate the moisture out of incoming air. This combination of high relative humidity and indoor dew point ultimately creates conditions that promote condensation or organic growth within the facility.

A Year-Round Solution for Indoor Building Health

The most cost-effective solution to verifying and ensuring long-term indoor building health is with a sensor capable of measuring key building health metrics like differential pressure, relative humidity, dew point, temperature, and CO2.

By gathering data on these building health metrics, the facility manager, operator, and/or building owner can quickly verify on-site conditions in real-time, while also gaining peace of mind in knowing their buildings are meeting engineering specifications per design as seasons change. In addition to these benefits, sensors’ data gathering gives users the ability to track and trend building health over a long-term period.

Using Data to Plan for Seasonal Building Health Changes

Getting and staying ahead of maintenance doesn’t need to start with expensive truck rolls and frequent site visits. Instead, sensor solutions provide an inexpensive, effective avenue to implement a proactive mindset. The collected data can be aggregated to an easy-to-use online portal capable of summarizing, visualizing, and diagnosing issues on site, while also granting users the ability to trend and predict HVAC performance for a lasting solution.
