Rotating Solar Capture Integrated with Charred Wooden Shingles and Cross-Laminated Timber Panels in Residential Design

Project in-detail

A rotating solar panel system combines with charred wooden shingles and cross-laminated timber to create an energy-efficient residential design that harmonizes with its natural surroundings.
5 key facts about this project
01
A rotating solar panel structure optimizes energy capture throughout the day.
02
The design incorporates charred wooden shingles for enhanced durability and aesthetics.
03
Cross-laminated timber panels provide structural integrity and thermal insulation.
04
The bent A-frame silhouette integrates the building with the surrounding landscape.
05
Large windows maximize natural light while minimizing energy loss through advanced glazing.
The "Fat Old Sun" project is a residential architectural design located in the Los Lagos region of southern Chile. This project emphasizes sustainability through innovative design and material choices, addressing both functionality and aesthetics in harmony with its natural surroundings. The design features a unique solar tracking system, a rotating solar panel that efficiently captures energy throughout the day, contributing to the building's overall energy self-sufficiency.

Sustainable Energy Solutions
A primary characteristic of this architectural design is its integration of high-efficiency photovoltaic panels. These panels are mounted on a large circular structure that rotates to follow the sun, maximizing energy capture. This dynamic feature distinguishes the project from conventional static solar designs and enhances its energy performance. The home incorporates both thermal and photovoltaic technologies, ensuring a continuous energy supply while minimizing reliance on external resources.

Open and Adaptive Spatial Design
The interior of the project utilizes an open floor plan, fostering a sense of spaciousness and flexibility. This design allows for fluid movement between spaces and enhances connection with the exterior environment. Large windows optimize natural light and reduce energy consumption through advanced glazing systems. This focus on maximizing daylight while managing thermal comfort reflects an intuitive response to the local climate, which can vary significantly.

Material Expression and Durability
Material selection plays a critical role in the project's sustainability goals. The use of wood for interior finishes contributes warmth and aesthetic appeal while supporting thermal insulation needs. The metal framework provides structural integrity, ensuring long-term durability in a region susceptible to diverse weather conditions. Additionally, the incorporation of recycled and eco-friendly materials aligns with the project's commitment to reducing its environmental footprint during construction and throughout its lifecycle.

The "Fat Old Sun" project exemplifies modern architectural approaches to energy-efficient living while maintaining a strong relationship with its landscape. The innovative solar tracking system, coupled with a flexible spatial design, positions this project as a valuable case study for sustainable residential architecture. For further insights into the architectural plans, sections, and detailed designs of this project, exploration of the presentation materials is encouraged.

Design a new small-scale home concept in the 10th edition of MICROHOME — 100,000 € prize + construction

Competition organisers

The 10th edition of the MICROHOME architecture competition invites architects and designers from around the world to explore the possibilities of compact, sustainable living. Hosted by Buildner in collaboration with Kingspan and Hapi Homes, this special edition challenges participants to design an off-grid, modular microhome for a young professional couple, with a maximum floor area of 25 m². Designs should prioritize innovation, efficiency, and real-world feasibility. 

A total prize fund of 100,000 € will be awarded, including three main prizes, the Kingspan Award, and the Hapi Homes Award, which will grant 15,000 € and lead to the construction of the selected design. The final registration deadline is September 25, 2025, and winners will be announced on Decebmer 9, 2025. For full competition details and submission guidelines, visit microhome.info.
