Nature’s Light Indoors in CLT homes
In the architectural realm, few elements contribute as profoundly to human wellbeing as natural light. When combined with the inherent sustainability and versatility of Cross Laminated Timber (CLT) construction, the result is living spaces that are not only environmentally responsible but fundamentally healthier for inhabitants.
At Arolla, our commitment to creating sustainable CLT homes leads us to craft spaces that nurture human health through thoughtful engagement with nature’s elements, particularly light.
How Natural Light Shapes Our Wellbeing
Natural light fundamentally influences our bodies’ internal rhythms. Exposure to daylight regulates circadian cycles, directly impacting sleep quality, mood stability, and overall mental wellbeing. Studies consistently demonstrate that well-daylit spaces can reduce cortisol levels (the stress hormone) while boosting serotonin production. These biological responses explain why spaces flooded with natural light feel inherently more welcoming and contribute to improved concentration, higher productivity, and reduced fatigue.
The implications are particularly significant in residential architecture, where homes serve as our primary environments for restoration and recovery. By prioritizing natural light in our CLT constructions, we create spaces that actively contribute to occupant health rather than merely housing them.
How CLT Enables Light-Optimized Spaces
CLT’s remarkable strength-to-weight ratio provides a significant advantage when designing light-filled spaces. Unlike traditional construction methods, CLT panels can span greater distances without intermediate support, enabling larger window openings that would be structurally challenging with conventional framing.
This unique characteristic allows our design team to incorporate expansive glazing elements, like floor-to-ceiling windows, clerestory lighting, and strategically placed skylights, without compromising structural integrity. The result is homes that maintain exceptional thermal performance while maximizing daylight penetration.
Additionally, CLT’s load-bearing capabilities facilitate open floor plans that allow light to flow unobstructed throughout the home. By minimizing internal walls and partitions, we create spaces where natural light can penetrate deep into the building’s interior, reducing reliance on artificial lighting and decreasing energy consumption.
Distributing Light Through CLT Structures
Effective daylighting extends beyond simply adding windows. Our approach includes several key strategies:
Strategic orientation: Each Arolla home is positioned to capitalize on solar paths, optimizing window placement to capture morning light in bedrooms and evening light in living spaces.
Light reflection: Interior surface finishes are selected to enhance light distribution. CLT’s natural wood finish provides a warm reflective quality that diffuses light beautifully throughout spaces.
Light shelves and reflectors: Architectural elements that redirect daylight deeper into rooms without increasing heat gain.
Thoughtful fenestration: Window placement considers both quantity and quality of light, with attention to preventing glare while maximizing illumination.
Timber and Light: A Natural Aesthetic Partnership
The natural warmth of exposed CLT surfaces creates a compelling interplay with daylight. As sunlight moves across timber surfaces throughout the day, it highlights the material’s organic textures and grain patterns, creating spaces that feel alive and responsive to nature’s rhythms.
This dynamic relationship between light and timber supports biophilic design principles, connecting occupants with natural elements to enhance wellbeing. The visual warmth of wood combined with abundant daylight creates environments that feel simultaneously energizing and calming, stimulating and peaceful.
Designing for Year-Round Light Optimization
Effective daylight design acknowledges seasonal variations. Our homes incorporate appropriate overhangs and shading elements that block harsh summer sun while welcoming lower-angle winter sunlight.
This passive approach to seasonal light management contributes significantly to energy efficiency while maintaining optimal light levels throughout the year.
Light as a Cornerstone of Sustainable Living
At Arolla, maximizing natural light is an aesthetic choice, but also integral to our vision of creating truly sustainable living environments. By leveraging CLT’s unique structural properties, we craft homes that harmonize human wellbeing with environmental responsibility. These light-filled timber spaces don’t just reduce energy consumption; they actively enhance quality of life, creating homes that support the health of both inhabitants and the planet.
