New Indoor Air Quality (IAQ) Solution Raises Consumer Confidence in Safely Returning to Offices & Hotels

Carbon Lighthouse’s IAQ solution improves air quality; building owners differentiate with occupant-facing app to confidently market good, stable IAQ

San Francisco (PR Newswire) Carbon Lighthouse, a cleantech leader focused on revenue-generating ESG solutions for commercial real estate (CRE), today released its new Indoor Air Quality (IAQ) solution, the only IAQ solution that shows real-time IAQ metrics for a building through a simple, occupant-facing app. The IAQ app is purpose-built to increase consumer confidence, such as when a tenant is considering their leasing options, an employee is reentering their workspace, or when a guest is booking a hotel. Today’s consumers have emerged from the early days of the pandemic knowing far more about healthy air than they did a year ago. A recent survey of 1,000 U.S. consumers showed that 91% of consumers recognize the importance of IAQ with 76% saying they’d want to see IAQ metrics on the public buildings they’re entering and 77% saying hotel IAQ would impact where they stay. With IAQ uniquely poised to influence consumers’ return to public spaces and therefore commercial real estate’s recovery, Carbon Lighthouse built its IAQ solution leveraging over a decade of deep expertise building and deploying advanced data-driven building controls which have been optimized through the company’s patented AI platform and its unparalleled data advantage from 100M sq. ft. of CRE analyzed. The result is that Carbon Lighthouse’s IAQ solution gives owners and operators the detailed instructions, streaming data, and marketable, on-demand IAQ metrics to confidently show their occupants that their building is optimized to provide good, stable indoor air quality.

“When the risks to human health and to the health of the business are this high, the tried and true attraction and retention strategies that worked even a year ago, are no longer viable. Only those building owners and property teams that can confidently market the safety of the air in their buildings will win back the trust needed to rebuild occupancy,” said Brenden Millstein, President overseeing Product at Carbon Lighthouse. “Carbon Lighthouse is proud to be using our decade’s worth of real building and HVAC expertise, enhanced technology platform, and our vast data-capturing capabilities to help CRE prove their impact-driven commitments to safety, wellness, and transparency to drive economic recovery across their portfolios.”

Carbon Lighthouse’s IAQ solution was designed to increase confidence among today’s leading workforce of which 50% are millennials who demand greater transparency across all areas of their lives and favor technology-enabled solutions. They share personal data with ease and view data transparency as a two-way street where they expect brands, employers, and others to share information back. With a Deloitte survey of millennials showing their top two post-pandemic concerns being healthcare/disease prevention (30%) followed closely by climate change (20%), periodically assessed building certifications will not suffice when it comes to forming an opinion about dynamic conditions like air quality or deeply concerning topics like the true sustainability of public buildings. Carbon Lighthouse’s IAQ solution uses real-time IAQ data to provide the demonstrable social responsibility the “S” in ESG to instill confidence among today’s battle-tested occupants that the air they’re breathing meets current quality standards and that building owners are proactively working to deliver healthy spaces for occupants and guests.

In six weeks, Carbon Lighthouse establishes a data stream to capture the most relevant IAQ data — CO2, Air Quality Index (AQI), Air Exchange Rate, Outdoor Air Percentage, Filtration Rating, Humidity, and Temperature — from existing building systems. Then, unique building data is analyzed against the 100M sq. ft of real CRE building data in its patented CLUES® AI platform to identify where site teams can quickly improve indoor air quality. Once good, stable air quality is achieved, owners decide when to turn on the occupant-facing app and have additional safeguards to ensure the building scores remain consistently good including:

  • Real-time alerts to instantly notify site team if ratings dip below “Good”
  • “In Review” ratings used when rare issues are being addressed by on-site teams
  • Sensors collect data and present an hourly building average reducing score volatility from ad hoc events that don’t pose material risk, such as the use of a vape pen
  • Continuous monitoring by Carbon Lighthouse and ongoing direct action by site teams ensures buildings maintain good air quality even as conditions change inside and outside the building.

In today’s increasingly competitive environment, forward-thinking CRE owners are choosing Carbon Lighthouse’s IAQ solution to differentiate their spaces and rebuild occupancy through marketable, transparent indoor air quality.

“As tenants plan to reoccupy office spaces, they are asking increasingly technical questions about indoor air quality. To earn peoples’ trust in our buildings and support our tenants’ efforts, we need to provide sophisticated answers and be transparent about what we’ve done and how we are managing ventilation systems,” said Eric Smith, EVP of Business Development at L&B Realty Advisors, LLP. “Thanks to Carbon Lighthouse’s IAQ solution, our property managers will be able to answer technical questions and demonstrate air quality in real time.”

“Air quality has always been important for hotels as we continuously turn over event spaces and guest rooms. But the pandemic has accelerated guest questions about IAQ, especially as group meeting planners start doing site visits for end-of-year events,” said Joe Ward, VP of Asset Management at Ohana Real Estate Investors. “With Carbon Lighthouse, we will be able to proactively show our IAQ scores and offer confidence that the air at our hotel is clean and filtered regularly, making it a competitive advantage we can even leverage with our leisure guests as well.”
