BLOG: The Overlooked Power of Airflow Optimization in Life Science Decarb
Airflow Optimization (AO) is a key solution to decarbonizing energy intensive life science research laboratories, yet its potential remains untapped in many companies. Airflow Optimization includes a variety of measures depending on the specific space such as demand control ventilation, fume hood variable air volume retrofits, variable air volume retrofits, and exhaust fan control can. A combination of these can cut lab HVAC energy consumption by around 50% or more for an immediate reduction in carbon emissions and attractive payback period bolster further by the large utility incentives available in many markets.
Longer-term and Strategic Benefits of Airflow Optimization
In net-zero buildings, the key is that initial decarbonization projects should focus on efficiency to permanently reduce electrical demand. One Life Science firm estimates that each dollar of capital spent to reduce demand via Airflow Optimization will save five dollars of future capital spending on electrification retrofits! That is because expensive electrical infrastructure and equipment (like heat pumps, electric boilers, or onsite solar) can be downsized. Appropriately sizing this equipment and intelligently controlling ventilation rates will also reduce operating and maintenance costs year after year, including reducing the amount of expensive clean electricity that must be purchased.
Airflow Optimization also offers strategic benefits. It lowers long-term electrical demand, saving on future electrification costs. AO systems also enhance safety protocols by capturing air quality data, empowering EHS teams. Specifically, the demand control ventilation piece of an airflow optimization project gives EH&S, facilities, and occupants confidence that their space will have more air, where and when needed, versus with a prescriptive approach to air change rates which was likely in place previously. Sometimes cultural norms and legacy processes hinder AO adoption. To overcome this, organizations must recognize the strategic importance of efficiency, address internal friction, and engage the executive team.
By investing in Airflow Optimization, companies can achieve high ROI projects, scale decarbonization efforts globally, and reduce future electrification costs. Additionally, it improves operational efficiency and safety practices, making it a worthwhile investment for lab owners.
