04
Employs stack ventilation to naturally regulate internal temperatures.
05
Integrates renewable energy solutions through an Ene Farm for energy efficiency.

## Overview

Located in Dubai, the "Cooling Envelope" residential design responds to the region's extreme climate by integrating sustainable strategies that target energy consumption reduction, particularly in air conditioning and artificial lighting. This project blends traditional architectural practices with modern innovations, aiming to enhance occupant comfort while minimizing environmental impact through passive cooling techniques.

## Cooling Strategies

**Air Movement and Thermal Regulation**: The design features a sophisticated system of air flow dynamics, utilizing screens, stacks, and tunnels to facilitate natural ventilation. These elements work together to enhance air circulation, allowing cool air to enter while warm air rises and exits through higher openings. This system significantly lessens reliance on mechanical cooling solutions.

**Water Management Systems**: Integral to the cooling approach is a network of water channels that collaborates with the stack effect to reduce temperatures and regulate humidity. By directing excess water back into the cooling systems, these channels enhance overall energy efficiency while contributing to the building's microclimate management.

## Materials and Innovations

**Advanced Material Selection**: The project employs Glass Reinforced Concrete (GRC) as the primary cladding material due to its lightweight composition, durability, and lower carbon footprint compared to conventional concrete. Additionally, a mesh structure provides a porous boundary that regulates air and light infiltration, while hygroscopic rock salt and hydrogel mesh enhance moisture control, supporting passive cooling methods.

**Light Integration Technology**: A Solatube (light pipe) system is utilized to direct natural light into the interior spaces, thereby reducing the need for artificial lighting during the day. This system contributes to the building’s energy efficiency and enhances the overall occupant experience by maximizing daylight access.

## Structural Configuration

The architectural layout adopts a modular construction approach, allowing for adaptability and potential future expansion. The ground floor includes communal spaces such as a dining area and courtyard, while the first floor is designed for private living quarters, incorporating a clear distinction between public and private zones. The consideration for future extensions exemplifies the project's flexibility and commitment to long-term usability.

In summary, the Cooling Envelope showcases a culturally sensitive design that harmonizes local architectural traditions with contemporary sustainable practices. The integration of community spaces further emphasizes the project’s focus on social connectivity within residential design.

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.
