Why Accurate Daylight Simulations?
Why Quantify Daylight?
Daylight is the #1 Office Perk
After 9 months of working in their new building with ample daylight, Lockheed Martin staff productivity had risen by 20% 1
Harvard Business Review cited a study that “access to natural light and views of the outdoors are the number one attribute of the workplace environment, outranking onsite cafeterias, fitness centers, and premium perks including on-site childcare” (Jeanne, Meister 2018)
Daylight has Benefits to Patients and Workers in Healthcare Buildings
A study of nurses in a hospital found that those exposed to more than 3 hours of daylight per day reported significantly less work-related stress and higher levels of job satisfaction. 1
A study showed patients’ length of stay was shorter for those near the window compared with those near the door. 3
Daylight Increases Alertness and Sleep Quality
Daylight stimulates your circadian pattern. When it is light out, your eyes send signals to the hypothalamus to feel alert. Work spaces without daylight can interfere with this process and cause a groggy feeling. 2
On average, workers in workplaces with windows slept 46 minutes longer per night than those without access to natural daylight in their workplace. 1
Using natural light as a resource reduces energy use and energy expenses. This lowers the electricity bill, and is better for the planet.
A study showed natural light can reduce your energy costs over 20% 5
Daylight Increases Educational Performance
Students at a school in California showed a 14% performance increase in standardized CAT scores (California Achievement Test) when moved into a day-lit design. 1
You can trust LightStanza to help reach your daylighting goals
LightStaza is proven within 4% accuracy as demonstrated with a Research Study*. Hence it can be trusted to deliver correct results for clients. LightStanza is more accurate than any other tool on the market! Having an accurate tool will improve design decisions, boost confidence when talking to clients, and deliver a project with a high quality daylight with all of its benefits.
LightStanza was Built for Reliability and Accuracy that Leading Firms Trust
LightStanza was founded in 2015 by a leading technical expert in the field. Other Industry Daylight tools may be less helpful.
LightStanza
Other Industry Daylight Tool
The other tool shows 20% daylight in a windowless closet. LightStanza reports no daylight in the closets.
The other tool shows the same values as the dark closet in a bright room. LightStanza shows the expected gradient.
LightStanza predicts the space to have a lively amount of daylight, receiving light from windows on both sides. The other tool under-predicts the amount of daylight these windows bring in. Since the other tool under-predicts in this area while over-predicts others it will be challenging to use as a design aid.
In order to enjoy the benefits of daylight, you need a tool you can trust, and daylight where you need it. LightStanza is proven accurate, and is the tool for sustainability consultants, architects, engineers and others looking to build the best daylit buildings
