Thermochromic Water Goblets and Drop-Stitch Construction in Vertical Algae Cultivation

Project in-detail

Constructed with thermochromic water goblets and drop-stitch construction, the vertical algae cultivation system demonstrates an efficient approach to sustainable biomass production.
5 key facts about this project
01
Constructed with thermochromic surface coating to regulate temperature and enhance energy efficiency.
02
Incorporates eight water goblets designed for effective rainwater collection and algae cultivation.
03
Utilizes drop-stitch construction for lightweight structural integrity and flexibility.
04
Features a nutrient supply system for optimal absorption of essential salts and CO2.
05
Designed specifically for vertical cultivation, maximizing sunlight exposure and space utilization.

The project focuses on vertical algae cultivation, designed to promote sustainability and efficiency in biomass production. Located in an environment favorable for algae growth, the design makes use of natural resources, including sunlight and rainwater. The concept blends modern agricultural techniques with responsible architecture, providing a practical approach to energy generation.

Vertical Cultivation System

At the core of the structure is a vertical cultivation system that optimizes space and maximizes sunlight access, which is essential for photosynthesis. This design allows for significant biomass production, supporting the harvesting of alternative energy sources. The layout emphasizes efficiency and streamlining the processes involved in growing and collecting algae.

Water Goblets

The project features eight water goblets specifically designed for rainwater collection, accumulating a total of 29,780,000 m³. These elements are important for reducing reliance on external water supplies, contributing to a self-sustaining cultivation environment. Their careful placement within the overall design enhances not only functionality but also aligns with the project's ecological goals.

Nutrient Supply System

A comprehensive nutrient supply system is integrated into the architecture, allowing for the absorption of essential nutrient salts and carbon dioxide, crucial for optimal algae growth. This approach ensures the healthy development of algae, supporting efficient production cycles. These integrated systems demonstrate an understanding of the complexities of cultivating marine biomass.

Advanced Materials

Advanced materials are employed to improve the ecological performance of the design. The thermochromic surface coating adjusts to temperature changes, enhancing energy efficiency. Drop-stitch construction techniques are used, providing strength and reducing weight in the structural components. Kevlar rope adds durability with its high strength and tear resistance, while aerogel serves an important role in insulation, reducing energy loss.

The design effectively creates a setting where algae cultivation thrives. It blends functional elements with advancements in material technology, all while emphasizing ecological responsibility and efficiency in production.

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.
