Our why... the science

We finally know how our circadian rhythms work, and what's needed to synchronize (entrain) our internal clock to the earth's rotation.


We need "bright days" and "dim nights". Without these signals at the right time of day, our sleep wanders. Over months, our sleep and our health degrades. We see a decrease in alertness, and an increase of illnesses such as diabetes, depression, cardiovascular disease, and even cancer.


There are three teams of experts who have published requirements for indoor lighting. Meeting these requirements through lighting and controls means that building occupants will be healthier. 


It's that simple.

We'll help you deliver your circadian solutions.

We believe that it is possible to improve the health of building occupants.

This way, we improve people' s health worldwide.

Lighting Specifiers
and Architects

Navigating the health implications of indoor lighting is difficult, especially if you don't know what to look for.  Where do you start? What next?


The good news is that the amount of lighting and the timing is well known. No matter where your project is, there are only three design approaches:

  • International WELL Building Standard (EML)
  • UL Design Guideline 24480 (CS)
  • DIN/TS 67600 (M-EDI)

 

We are experts at all three. Give us a shout and let us know that you'd like to find out more.

Manufacturers

Luminaire and control manufacturers have to know that the products they market are going to sell.


The good news: Any light source contributes to the circadian goal, whether it's "white tunable" or a "fixed CCT".  The issues are efficiency, flexibility and cost.


Our advisors developed the existing test methodologies for circadian luminaire scores and for circadian space scores, so we know how solutions are measured and verified. We know how a manufacturer would use circadian scores to produce luminaires that sell. We also know why products are often VE'd, and what to do to reduce this.


Let us work with you so that you can book more revenue and take more market share.

Manufacturer's Rep Agency

The typical rep agent has 60 or even 100 manufacturers that they represent. Rep agencies compete through their reputation, as their knowledge of the manufacturers they represent is critical.


Supporting the lighting design community with education, recommendations and spec sheets is what they excel at. They need to know their products.


But what luminaires do they suggest when a health project comes along? More importantly, what questions do they ask their customers to ensure that they know the project's design goals?


There are a few rep agents who address this well, and they have seen their business grow.

Lighting Distributors
and Contractors

Circadian lighting projects are becoming more prevalent. Making certain that your people know the issues and the language of health and lighting is important. We know what you need to know, and how to speak to the other disciplines. 


Wondering what happens when a lighting-for-health project gets VE'd? We can help you understand the implications and the upcoming challenges.


We taught at the university level, and we've given talks to the lighting distributor and contractor markets.


After an initial discussion, we will deliver a program designed to teach your staff the issues.

Building Owners

The real estate sector has its challenges. Today, market influencers are many, from high interest rates, COVID, AI and ESG, how you manage your business will determine where you will end up. 


Adding circadian effective lighting to your options for new leases just makes sense. 


Imagine how prospective tenants will favor your properties where you can deliver a unique value for their employees: greater alertness during the day, and less incidents of diabetes, depression, cardiovascular disease, and even cancer.


Offered as a Tenant Improvement, the costs are paid for in the lease.

Influencers

As you write and talk about issues impacting the lighting community, you want to help your audience know about emerging shifts in the market.


Circadian-effective lighting has been around for a while, but it's only taken hold in recent months. The facts surrounding lighting and health are complex, and the industry certainly wants to sell more expensive systems.


What's actually happening, and how do the different sectors navigate through the turmoil?


Let's talk about the impacts of healthy lighting, and help your audience deliver positive results.

FAQ

  • Who are we?

    We're a group of experienced circadian lighting experts who developed the existing methods for:

         • Creating a circadian luminaire score methodology

         • Developing the site that enables lighting specifiers to search for luminaires

         • Creating a method for capturing thousands of measures in an indoor space and outputting a floor plan illustrating the circadian scores


    In other words, we've got the market know-how to help companies from the lighting industry deliver circadian solutions that meet your customer's needs. 


    So you're in good hands.

  • Are circadian lighting projects on the rise?

    Yes, they are, but it's taken a while.


    Back in 2015, there were claims that the circadian lighting market would be a multi-billion dollar market by 2022. Confusion about the science was the major cause of delay. 


    Today, with three published guidelines informing us about the quality of light and the timing schedule required to deliver the health results, we are finally seeing traction. 


    Circadian Lighting Advisors was created to accelerate that traction. Our commitment is to show you how you can make more money offering circadian solutions. 

  • How did we get here?

    Today, people indoors are not receiving the "bright days" and "dim night" signals that are needed to keep us alert and healthy. 


    The signal is needed to synchronize (entrain) our circadian rhythm (an average of 24.2 hours) to the earth's rotation (slightly faster at 24.0 hours).


    Over time, our sleep quality degrades and so does our alertness and our health. 


    This was not the case before the 1970s. Why? During the energy crisis we learned that — to avoid borrowing money from China to pay the Middle East for fossil fuels — we could turn our attention to saving energy. 


    On analysis, buildings used a large amount of energy (35–40%). HVAC and lighting were the largest components. HVAC was tough, so we focused on lighting. 


    At the time, Illumination Engineering Society (IES) recommended 1000 lumens indoors.  Over the years we lowered the amount of recommended lumens, and lighting technology advanced. Where energy usage used to be over 1 watt per square foot, we've now achieved about 0.4 watts per square foot.


    Today IES recommends 350–500 lumens indoors.  We've since learned that this is not enough.


    It turns out that simply controlling lighting indoors can correct for this. 


    Three industry task forces have published the lighting needed, and the schedules. 


    Circadian Lighting Advisors offers consulting services to advance the lighting industry. 

  • Where are you offering advisory services?

    Our team is a global team, and we are ready to deliver services anywhere. 


    As far as market readiness, Europe is ahead, with projects in hospitals, nursing homes, and even high-profile corporate offices.


    North America is already seeing an uptick in circadian lighting projects. One case study by Kolar was published by UL Solutions. 


    Asia is a little behind, and recently introduced the WELL Building Standard and associated services.

  • How do you approach each project?

    Our advisors – while well versed in circadian practices – first have to understand your perspective before we can develop a strategy. 


    We strive to make that happen in our first 30-minute meeting. 


    Then, we deliver a proposal based on what we determine your needs are.

  • Where did the idea of advisory services come from?

    We have talked to hundreds of lighting professionals over the past 6 years. 


    The idea that advisory services are needed before companies can adopt a program came from listening to you.
