Is the Quest for Energy Savings Killing your Indoor Air Quality?
Chris White • May 4, 2026
The importance of building green or implementing green initiatives in existing buildings is on everyone’s mind. The top three outcomes building owners want to achieve by going green are:
Going green saves money, but it can adversely affect your indoor air quality.
- 1) Lowering operating costs (energy savings).
- 2) Having a healthier indoor environment (indoor air quality).
- 3) Helping the environment.
I’ve written about energy savings, but how does indoor air quality (IAQ) tie into the equation?
Energy savings and its effect on IAQ
- A lot of focus is put into making a building super “tight” for energy saving purposes. This means wraps, sealants, foams, insulation, etc. are used to reduce air infiltration. These features are excellent for energy savings, but reducing infiltration ventilation in a building can cause indoor mold growth (a large contributor to poor IAQ) and a buildup of indoor air pollutants.
- The importance of indoor air quality
- Good indoor air quality is important for many reasons. We spend so much of our time indoors, and poor IAQ can impact our health, comfort, and productivity. It’s been well-documented that businesses with IAQ issues have experienced decreased employee productivity, increased employee sick days and increased costs of employee medical care.
- Energy Savings vs. Indoor Air Quality
- So you’re probably wondering what all of this means and if you’re going to have to make a trade off between saving energy or improving IAQ. The answer is no–you don’t have to choose one or the other. You can have both by balancing reduced air infiltration and proper ventilation. It’s all part of building science. When you control the outdoor air entering your building rather than letting it enter through cracks, unsealed joints, or leaks, your building can achieve both better IAQ and energy efficiency.
- If planning new construction, make sure you and your contractor, architect, engineer, or consultant design an appropriate and effective mechanical ventilation system. If tightening an existing building, make sure any necessary updates are made to your ventilation system. In both cases, it’s important to keep your system maintained. Doing so can save you a lot of time, money, energy and headaches in the long run.

If you’re like me and not in the path of Hurricane Laura, you’ve spent a good bit of time watching Hurricane Laura news coverage. So far it looks like the surge wasn’t nearly as bad as predicted, but Hurricane Laura caused a tremendous amount of damage to Cameron and Calcasieu parishes and the surrounding areas. It’s also too soon to tell how much damage Hurricane Laura will cause as the storm moves inland and dissipates. What’s certain though, is Hurricane Laura will leave a considerable amount of water damage, resulting in water damage restoration and mold remediation. Hurricane Laura environmental cleanup is going to be a huge undertaking and will cause disturbance of asbestos, lead, PCB, and mercury. Proper removal and disposal of those materials is super important. Typically, storm coverage emphasizes water damage and mold remediation. Water damage restoration and mold remediation after Hurricane Laura will be the most obvious cleanup and restoration tasks. But everyone involved with Hurricane Laura environmental cleanup has to consider the other environmental hazards they could encounter. Hurricane Laura environmental cleanup will take time. Response work, particularly environmental cleanup, must balance speediness and caution. This is particularly important since we’ll want to get out right away and assess damage as soon as Hurricane Laura clears out. I know everyone wants to get in and get everything cleaned up and put back together. When we went through Hurricane Gustav (and other storms over the years), I was the same way. But sometimes hasty cleanup efforts can make more of a mess if we don’t slow down and assess all the potential environmental hazards in the work area. We may also put ourselves, co-workers, friends, and family at risk if we unknowingly create an environmental problem. Your safety is the most important consideration. Whether it’s water in the roadways, downed power lines, unstable structures, or contaminated water, make sure it’s safe to move around before you try to get in and assess the damage and environmental hazards. And when the storm is over, we often see hot temperatures return. Dehydration, heat exhaustion, and heat stroke are common problems people face. You’re stressed out and exhausted, and now you’re working in the heat, trying to put your home or business back together. Take care of yourself, then worry about contents – it’s worth repeating that you can always replace buildings and contents, but not people. You can replace buildings and contents, but not people. I won’t get too far into avoiding mold and mold remediation, other than to stress that you need to get the building clean and dry. Maybe Hurricane Laura is the only cause of the mold. Or maybe there’s an ongoing moisture problem that existed before the storm, and now the recovery work has led to discovery of other moisture problems. Find the cause, get the building dried out, cleaned up, and keep the mold from coming back. One other quick reminder on water damage restoration and mold remediation: there is no such thing as a Mold Free Certificate . There’s no requirement to get your home or building certified as “mold free” to make sure you can sell or rent a home or building. Anyone trying to sell you a mold free certificate is trying to scam you. Period.
