Sustainable Hotel Design: A Deep Dive into Green Solution House by 3XN
This article explores Green Solution House by 3XN, showcasing its achievements in sustainable hotel design and architectural innovation in Rønne, Denmark.
Nestled in the picturesque town of Rønne, Denmark, Green Solution House stands as a beacon of sustainable hotel design and architectural innovation. Spearheaded by the renowned architectural firm 3XN, this project spans an impressive 4500 m² and was completed in 2015. Through the lens of sustainability, Green Solution House showcases how hotels can embody eco-friendly practices without compromising on luxury or comfort.

A Vision for Circular Sustainability
The Core Objectives
At its heart, Green Solution House is dedicated to three core objectives: demonstrating green solutions, promoting continuous improvement, and enabling knowledge sharing. This vision is brought to life through a holistic approach to sustainability, earning the building certifications such as DGNB, Active House, and inclusion in the Cradle to Cradle registry.


Design and Innovation
The architectural and design choices reflect a deep commitment to the environment. From the renovated hotel rooms to the new conference building, each element is integrated into the surrounding nature park. Seasonal lakes onsite ensure water management and create habitats for local biotopes and endangered species, emphasizing the hotel’s role in environmental stewardship.

Harnessing Nature and Technology
Interaction with Nature
Guest comfort at Green Solution House is paramount, achieved through an immersive experience with nature. The design maximizes the presence of the surrounding natural beauty, clean ocean air, and abundant daylight, enhancing the guest experience.

Technological Integration
The project also pioneers in integrating technology with sustainability. Smart hotel rooms feature a custom-designed app to track the environmental impact of each stay, monitoring metrics such as water and energy consumption, air quality, and more. This interactive approach not only educates guests but also encourages eco-conscious behaviors.

Material Choices and Construction
Selective Material Use
A unique material filter was developed to select environmentally friendly materials, prioritizing factors like recyclability, social responsibility, and energy efficiency. This resulted in innovative uses of local resources, such as upcycling waste streams from local manufacturers and utilizing leftover materials in construction, further minimizing the project's carbon footprint.

Local and Active Materials
The project emphasizes local sourcing and the use of active materials that purify the air. Interior elements like carpets, plasterboard, and roofing materials contribute to cleaner indoor air, while the extensive use of windows and skylights ensures natural light permeates the building, reducing the need for artificial lighting.

Towards a Sustainable Future
Circular Sustainability in Practice
Green Solution House is a living example of circular sustainability, where the concept of waste is eliminated, and materials are designed to be disassembled, recycled, or biodegradable. This approach is evident in the regenerative systems employed, such as algae filters for wastewater treatment and systems transforming kitchen leftovers into clean energy.


Impact on Local Ecosystem
The integration of local biotopes and the focus on serving local produce in the restaurant underline the project’s commitment to supporting and enhancing local biodiversity and economies.

Green Solution House by 3XN is not just a hotel; it is a pioneering example of sustainable hotel design. It demonstrates how the hospitality industry can lead the way in environmental responsibility while offering guests a unique and enriching experience. This project serves as an inspiration for future endeavors in the realm of sustainable architecture and green design, proving that luxury and sustainability can go hand in hand.
