Biomass Heating With Miscanthus and Recycled Materials in a Sustainable Residential Design

Project in-detail

Utilizing the energy potential of Miscanthus and incorporating recycled materials, this residential design achieves sustainability while providing a modern living environment.
5 key facts about this project
01
Utilizes Miscanthus as a primary biomass heating source, reducing reliance on fossil fuels.
02
Incorporates recycled facade panels to enhance thermal insulation and minimize environmental impact.
03
Features an inclined roof that facilitates effective rainwater collection for household use.
04
Employs multi-functional spaces designed for adaptability and efficient family living.
05
Constructed using a timber frame that emphasizes sustainability and local material sourcing.
The Silvergrass House exemplifies contemporary residential architecture that emphasizes sustainability and energy efficiency. Located in a suitable climate for biomass cultivation, this project leverages the potential of Silvergrass (Miscanthus giganteus) as a renewable energy source. The design integrates innovative materials and efficient systems to create a functional living space while minimizing environmental impact.

Unique Design Approaches

The architecture of the Silvergrass House incorporates several distinct elements that differentiate it from standard residential designs. An inclined roof design serves multiple purposes, facilitating natural rainwater collection that can be filtered for household use. This adds a layer of sustainability and enhances the overall ecological footprint of the home. The roofline not only provides practical benefits but also contributes to the home's aesthetically pleasing profile.

Another unique approach is the centralization of heating sources, with the kitchen stove and hot-water boiler positioned to maximize thermal efficiency. The fireplace, made of concrete for its heat retention properties, allows for effective warmth distribution throughout the interior spaces. This configuration reflects careful planning in both functionality and energy management, which is often overlooked in conventional housing designs.

Multi-functional spaces are also a hallmark of this project, ensuring adaptable use throughout different areas of the home. This flexibility supports various activities for the occupants, catering to modern living demands without compromising space or comfort. Large windows strategically placed around the home contribute to natural lighting, promoting an indoor environment that reduces reliance on artificial illumination.

Material Selection and Environmental Integration

The choice of materials in the Silvergrass House underscores a commitment to sustainability. Timber columns provide structural support while promoting responsible sourcing, while recycled plywood is employed for flooring to minimize waste. Facade panels made from recycled production waste, enhanced by polystyrene insulation, optimize thermal efficiency. The combination of oak boards in the roof structure delivers aesthetic appeal alongside durability.

This project highlights a significant advancement in integrating renewable energy sources into residential design. By utilizing local biomass for heating, the Silvergrass House not only meets its energy needs but also has the potential to support nearby structures. This strategy creates a community impact that elevates the project beyond individual home design, illustrating a forward-thinking approach to energy consumption.

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.
