The LED light skirt indicates whether structure is generating more or less energy than it is using. If the skirt turns green, the building is using less energy than it produces, when yellow, energy use is breakeven, and when it turns red, the building is using more than it is producing. The Rockwood Main home is the subject of [LEED certification](https://www.trendhunter.com/trends/rewild-homes). Because of the prefabrication, they can be built off-site and located nearly anywhere. ## Trend Insights (Trend Hunter) - Score: 3.3/10 - Popularity: 62% | Activity: 28% | Freshness: 8% - Audience gender: 50% men, 50% women - Primary generations: Millennial, Gen X - Top markets: North America, Europe ## Categories [Trend Hunter](https://www.trendhunter.com/trends) > [Eco](https://www.trendhunter.com/eco) ## Key Themes ### What's Driving This Trend - **Energy Efficient Buildings:** Opportunity for disruptive innovation in designing and constructing buildings that generate more energy than they use. - **LED Technology:** Opportunity to create innovative LED lighting systems that visually indicate energy usage in buildings. - **Prefab Construction:** Opportunity for disruptive innovation in the off-site construction of energy-efficient buildings. ### Who This Affects Most - **Architecture:** Opportunity for architects to incorporate energy-efficient design principles into their projects. - **Lighting:** Opportunity for lighting companies to create innovative LED systems for energy monitoring. - **Construction:** Opportunity to revolutionize the construction industry with off-site prefabrication technology. ## Related on Trend Hunter - [Water-Powered Family Residences](https://www.trendhunter.com/trends/breach-house.md) - [Solar Powered Compact Homes](https://www.trendhunter.com/trends/e55000.md) - [Bright Family Renovation](https://www.trendhunter.com/trends/cobble-hill-townhouse.md) - [Off-Grid Solar Panel Residences](https://www.trendhunter.com/trends/florian-busch-architects.md) - [Slender Alley Dwelling Revivals](https://www.trendhunter.com/trends/brown-house-1.md) - [Barn-Inspired Timber Residences](https://www.trendhunter.com/trends/house-w-1.md) - [Forest Lantern Homes](https://www.trendhunter.com/trends/iside-home.md) - [Climate-Responsive Prefab Homes](https://www.trendhunter.com/trends/drop-pod.md) - [Sustainable Light Designs](https://www.trendhunter.com/trends/geolectric-lantern.md)
