5 key facts about this project
01
Unique spiral form enhances natural airflow and ventilation.
02
Thermal mass reduces heating and cooling needs through energy efficiency.
03
Green roof provides insulation and fosters outdoor community engagement.
04
Designed with southern-facing windows for optimal sun exposure in winter.
05
Integrated features support multipurpose community activities and gatherings.

The eSPIRAL SPIRALA COMMUNITY CENTER is located in an area that emphasizes sustainability and community involvement. The design takes cues from the natural world, especially the spiral shapes seen in seashells and fronds of ferns. Functioning as a community hub, the center supports social gatherings and collective activities while prioritizing energy efficiency.

Design Concept

The design incorporates passive heating and cooling techniques that enhance comfort without heavy reliance on energy sources. Southern-facing windows are configured to collect sunlight in winter, which provides warmth. During summer, roof overhangs block excessive solar heat. This careful balance leads to a comfortable environment throughout the year.

Building Form and Thermal Mass

The form of the building is embedded into the earth, using its natural thermal mass to help regulate temperature. It absorbs heat during the day and releases it slowly at night. This feature reduces the need for artificial heating and cooling, showcasing an effective way to minimize energy consumption while improving comfort.

Community Integration

The layout of the center supports a range of activities. It includes spaces such as a southern solar lobby, multipurpose areas, and a kitchen, as well as restrooms. The arrangement promotes interaction among visitors. By designing the space with community functions in mind, the center fosters a sense of belonging for its users.

Site and Surroundings

The site plan includes important infrastructure like electricity, potential eco homes, and water sources such as ponds and boreholes. The design takes into account the natural slope of the landscape, which enhances the integration of the building with its environment. This connection not only benefits the design but also improves its energy efficiency.

The green roof acts as both insulation and a space for outdoor activities. It encourages interactions among community members and strengthens their connection with nature, embodying the center's mission to foster community relationships within a natural setting.
