A 3D map is a visual model that represents locations and shapes in three dimensions—length, width and height—so users can perceive depth and spatial relationships that flat maps hide. For investors, 3D maps matter because they power products and services across areas like construction, logistics, real estate, autonomous systems and medical imaging; clearer spatial insight can reduce project risk, reveal efficiency gains and influence a company’s growth or competitive position.
sun-path visualizationtechnical
A sun-path visualization is a chart or diagram that shows the sun’s position in the sky at different times of day and seasons for a specific location. Investors use it to estimate how much direct sunlight a site or rooftop will receive—critical for projecting solar panel output, energy revenue, building heating and cooling needs, or shading risks—much like using a route map to position chairs where they’ll catch the most sun.
shadow analysistechnical
A shadow analysis is an independent, duplicate review of the same data and calculations that a company used to reach a result, run separately to confirm those findings. Think of it like someone redoing a recipe step-by-step to make sure the cake turns out the same; for investors, it helps reveal errors, biases or selective reporting that could affect a company’s claims and therefore its stock value, regulatory standing, or future cash flows.
solar planningtechnical
The process of designing, organizing and preparing a solar energy project from idea to operation, including choosing the site, mapping panel layout, securing permits and grid connections, arranging finance and scheduling construction. Investors care because thoughtful planning shapes how much power the project will produce, how quickly it starts earning, and how likely it is to face cost overruns or regulatory delays — much like a clear blueprint and timeline improve the odds a building is finished on time and on budget.
3d geometrytechnical
Three-dimensional geometry is the study and description of shapes, surfaces and volumes in space — think of how a sculptor shapes clay or how a 3D printer builds an object layer by layer. For investors, it matters because 3D geometry underpins design, prototyping and manufacturing across industries like medical imaging, manufacturing, gaming and AR/VR, influencing product capability, development cost, time to market and potential competitive advantage.
walk scoretechnical
A walk score is a numerical rating that measures how easy it is to accomplish everyday errands on foot from a specific address, based on proximity to shops, schools, transit and other amenities. For investors, it acts like a convenience meter — higher walkability often means stronger demand, higher rents or property values, and better foot traffic for retail locations, while lower scores can signal reliance on cars and potential leasing or sales challenges.
ai featuretechnical
An AI feature is a specific tool or capability within a product or service that uses artificial intelligence to perform tasks like recognizing patterns, making recommendations, automating decisions, or improving efficiency — think of it as a smart assistant built into an app. Investors care because these features can make offerings more attractive, lower operating costs, speed growth, and create competitive advantage, but they also carry execution, data-privacy, and regulatory risks.

From 0-100, home searchers can easily see how much sunlight a property receives. Sunscore was co-developed with Shadowmap and is available exclusively on Redfin.
SEATTLE--(BUSINESS WIRE)--
Redfin (redfin.com), the real estate brokerage powered by Rocket, today launched Sunscore, a property-level score that tells home searchers exactly how much natural light a home receives from 0-100. The launch marks an exclusive U.S. partnership with the developer of Sunscore, Shadowmap, which provides a global interactive 3D map for sun-path visualization, shadow analysis and solar planning.
“We know from customer feedback that sunlight is a priority for house hunters,” said Ariel Dos Santos, Redfin’s Chief Product and Design Officer. “When you tour a home, you want to see brightly-lit spaces with natural light pouring through windows. Sunscore gives home searchers that information upfront in a simple-to-understand way.”
Each home’s Sunscore is based on the property’s 3D geometry and surrounding 3D shadows caused by things like terrain, trees and buildings. The property’s surface is analyzed toward the sun at various points throughout the day, at different days of the year, to get a full picture of potential shadows. The more sunlight available, the higher the Sunscore, from 0-100. For example: If the home’s Sunscore is 80, that rating is “super sunny,” and home searchers can expect minimal shadows impeding sunlight throughout the day.
According to Georg Molzer, CEO of Shadowmap, “The sun influences how we live, affecting our health, comfort and happiness. However, sunlight availability is often uncertain when purchasing or renting a property—especially across different seasons. We bring clarity! Sunscore, powered by Shadowmap’s 3D sunlight analysis technology, assists buyers in understanding a property’s sunlight exposure before they decide, integrating sunlight insights directly into Redfin’s real estate search.”
Natural light is an important feature for many homebuyers. According to a recent Redfin survey, nearly 70% of people say the amount of sunlight in their home affects their satisfaction with their living situation, and 11% say it’s non-negotiable when searching for a home. Not only does sunlight provide aesthetic charm and mood-boosting serotonin, there are practical and financial benefits, too. Information on property-level sunlight tells what a home’s solar potential looks like, which could save homeowners thousands of dollars per year in energy costs over time.
“Sunscore brings clarity to both the emotional and functional value of sunlight. In places like Southern California, buyers are essentially paying a ‘sunshine tax,’ so you better believe natural light matters,” said Kellie Martinez, a Redfin Premier real estate agent in Orange County. “It’s one of the first things people notice during a showing and is a true influencer.”
Sunscore is now available on all for-sale homes listed on Redfin.com and will be available on Redfin’s iPhone and Android apps later this year.
Sunscore marks another way Redfin provides customers with the most detailed information possible to help them find the perfect home. Last November, Redfin launched conversational search, an AI feature that allows home searchers to have a back-and-forth dialogue with Redfin about specific home preferences. Redfin offers climate data from First Street on every property, so people can understand the potential risk for flood, fire, heat, wind and air quality. Walk Score is also available for every property, which shows a home’s walkability, bike-ability and access to transit on scales of 0-10.
