Natural cooling
Green roofs and facades keep buildings cooler during summer heatwaves.
GREEN DESIGN FOR IMPROVED INDOOR CLIMATE
Poor air quality and high indoor temperatures impact health and productivity, and noise pollution undermines comfort, health, and productivity. Buildings that fail to regulate these factors create stuffy spaces and unproductive workdays.
Temperature regulating all year round
Green systems reduce heat loss in winter and stabilize indoor climate.
Improved Air Quality, Reduced Noise
Plants filter fine dust, improve humidity, and reduce noise indoors.
Our natural solution for indoor climate control
Green roofs and walls create a healthier indoor climate. Greenery reduces stress, supports relaxation, and lowers complaints like headaches, tiredness, and irritation. Living and working in a green environment has a positive effect on the well-being of people

INVEST IN PEOPLE’S WELL-BEING
Sempergreen roofs and SemperGreenwall Indoor systems transform buildings into healthy places to live and work. Greenery cools, cleans the air, and reduces noise. More than energy savings, they provide comfort, relaxation, and focus — an investment in the well-being of people every day.
Green design also supports a healthier indoor climate: complaints such as irritated eyes, headaches, dry throat, and fatigue decrease. In offices with sufficient greenery, absenteeism rates are shown to decline.

Green Walls
Poor indoor air quality is a silent issue in many buildings. Pollutants from paint, adhesives, and office equipment – such as benzene, xylene, and ammonia – circulate daily, leading to headaches, fatigue, and loss of focus. The indoor living wall solutions of Sempergreen provide a natural solution.
By integrating proven air-purifying plants such as Asplenium, Chlorophytum, Phlebodium, Philodendron monstera, and Spathiphyllum, the wall filters out harmful substances while releasing moisture into the air. This improves humidity, prevents dryness, and creates a healthier, more productive indoor environment – all wrapped in a striking green design.

Turn down
the noise
Echo and background noise can make any space feel restless and tiring. An indoor plant wall changes that instantly. The lush greenery absorbs sound, creating calmer and more comfortable environments in offices, schools, hotels, and public spaces. Independent acoustic tests confirm the strong sound-absorbing performance of the SemperGreenwall Indoor, reducing noise by up to 85%.
Beyond the numbers, people simply notice the difference: clearer conversations, less distraction, and a more relaxed atmosphere. At the same time, the wall adds a striking design feature that brings nature indoors. With Sempergreen, you don’t just create a green wall – you create a quieter, healthier, and more enjoyable place to be.
Cooling
from Above
Traditional black roofs absorb extreme amounts of heat, raising indoor temperatures. A Sempergreen green roof lowers roof surface heat by up to 40°C. Beneath, rooms stay 3–5°C cooler in summer, reducing the need for air conditioning. In winter, the system limits heat loss through its insulating substrate and vegetation layer. This results in heat regulation, reduced CO₂ emissions, and a more stable indoor climate all year round.
In addition, green roofs absorb sound, creating quieter and healthier environments inside.
Smart Systems for the Ultimate Indoor Climate
Sempergreen offers proven green roofs and living walls that reduce heat absorption, improve insulation, and clean the air. Whether on roofs or façades, our systems improve comfort, cut energy costs, and help create healthier indoor environments.

All About Indoor Comfort
Find answers to the most common questions about how green roofs and walls improve indoor climate, comfort, and energy savings.
Does a green roof have an insulating effect?
Yes, green roofs provide sound insulation. The combination of plants, substrate, and air layers absorbs and reflects sound waves. Research indicates noise levels can be reduced by up to 8 dB, which sounds about 50% quieter to the human ear.
Do plants improve indoor air quality?
Absolutely. Plants filter harmful particles such as fine dust, absorb CO₂, and produce oxygen. They also release moisture through evaporation, which improves indoor humidity. This reduces issues such as dry eyes and supports healthier, more comfortable spaces.
Can green roofs and walls reduce energy bills?
Yes. Reduced need for air conditioning in summer and heating in winter results in significant energy savings.
Do living walls reduce ambient noise indoors?
Yes. A SemperGreenwall Indoor acts as an effective sound barrier. Independent tests show it absorbs up to 85% of ambient noise (αw 0.85). Please note: the exact acoustic value depends on factors such as room size, ceiling height, construction, and furnishing.
Do green systems affect well-being?
Yes. Green roofs and walls reduce stress, promote relaxation, and create healthier environments. Studies show fewer complaints such as fatigue, headaches, and irritation in greener spaces.
