Adaptive Facade with Mechanical Mesh for Enhanced Solar Harvesting

Project in-detail

Equipped with an adjustable mechanical mesh facade that optimally captures solar energy while addressing glare, the structure embodies a commitment to sustainability and efficient energy management designed for modern occupancy.
5 key facts about this project
01
Facade panels rotate mechanically to track sunlight.
02
An adjustable mesh layer manages glare and light exposure.
03
Inspiration drawn from floral orientation towards sunlight.
04
Enhanced surface areas maximize solar radiation capture.
05
Design aligns with Saudi Arabia's 2030 sustainability goals.

The Wahaj project is located in Saudi Arabia, a region that benefits from abundant sunlight year-round. The design aims to harness this natural resource by focusing on solar energy for sustainable power generation. This approach aligns with the country's vision for 2030, which emphasizes a reduction in fossil fuel reliance and encourages the use of renewable energy sources. The project reflects a commitment to sustainability and engages thoughtfully with its surrounding environment.

Maximizing Solar Energy Collection

The architectural concept prioritizes efficiency in solar radiation collection. The facade features expanded surface areas on the south, east, and west sides to optimize solar energy harvesting. This careful planning contributes to overall energy efficiency, reinforcing the project's aim to create a more sustainable structure.

Adaptation to Environmental Influences

Inspiration from nature plays a key role in the design. The building's elements mimic the way sunlight moves and how flowers turn towards the light. The facade panels are designed to rotate mechanically and are arranged in an Islamic pattern, allowing them to track the sun's path during the day. This adaptability enhances energy capture and integrates aesthetic considerations with functionality.

Innovative Control Elements

A distinctive aspect of the facade is its secondary layer, which helps manage glare and light exposure. Below the primary solar panels, there is an adjustable mechanical mesh that can be modified to control the amount of light entering the interior. This feature enhances user comfort while effectively managing solar gain. Additionally, at night, the panels close automatically to conserve energy, underlining the project’s focus on energy efficiency.

Design Cohesion and Functionality

Although specific materials are not discussed, the design suggests the use of components that enhance solar absorption while minimizing reflections. The relationship between aesthetic qualities and practical functions is evident, making the Wahaj project a relevant example of contemporary renewable energy architecture. An important design detail is how the mechanical systems integrate with the overall facade, showcasing a clear understanding of both practicality and visual appeal.

MICROHOME 10: Celebrating Small-Scale Living with €100,000 Prize Fund and Kingspan’s Innovation

`
Competition organisers

The MICROHOME 10 competition invites participants to submit visionary designs for off-grid, modular microhomes that push the limits of sustainable, small-scale living. Organised by Buildner in partnership with Kingspan and Hapi Homes, this tenth edition sets the challenge of designing a dwelling for two people within a maximum floor area of 25 m², encouraging bold solutions adaptable to any urban or rural location. The competition continues Buildner’s mission to foster innovative approaches to compact, energy-efficient housing that can address pressing global challenges.

This year’s edition offers a generous total prize fund of €100,000, including the Kingspan Award for designs that integrate high-performance Kingspan products and the Hapi Homes Award for a project selected for real-world construction. In addition to cash prizes, the winners gain international exposure through Buildner’s media partnerships, publications, and a dedicated MICROHOME magazine, further amplifying their ideas to the wider architectural community.

Key dates for MICROHOME 10 include the closing date for registration on 25 September 2025, the submission deadline on 29 October 2025 (11:59 p.m. London time), and the announcement of winners on 9 December 2025. These milestones ensure participants have clear timelines to develop and present their concepts, with early registration discounts available to support students and emerging designers worldwide.
