GreeNest: NEST Ingrained Ecosystem for Zero Emission Buildings

European Energy Innovation Magazine

This article explores the GreeNest project’s mission to revolutionise sustainable construction by integrating biogenic materials, renewable energy systems, and innovative smart envelope designs. With solutions such as the EcoTechWall, Heat-Harvest Window, and GreenWall, the project aims to reduce embodied carbon emissions by 50% and operational emissions by 60%. By emphasising circular design, digitisation, and local supply chains, GreeNest supports EU climate goals, creating adaptable, low-emission buildings that enhance comfort, biodiversity, and energy efficiency across Europe.

Multi-Criteria Assessment of Energy Systems at an Office Building

19th Advanced Building Skins Conference 

This article, presented at the Advanced Building Skins 2024 conference, examines the evaluation of 216 different retrofit scenarios that combine passive and active energy systems for an existing office building. The study assesses each case based on four key performance indicators: primary energy consumption, CO₂ emissions, net present cost (NPC), and thermal comfort. Using the PROMETHEE method for multi-criteria decision analysis, the optimal solutions are identified under varying weighting schemes. The results provide valuable insights for designing low-carbon, cost-effective, and comfortable buildings that align with EU climate targets.

KA-RZ: A Sustainable Building Material Made from Coffee Grounds

Press release

This article introduces KA-RZ, an innovative insulating material developed by GreeNest partner K-MÄLEON, made from recycled coffee grounds. By combining organic residues with a natural foaming agent, KA-RZ achieves strong thermal performance through a low-energy, room-temperature process. At least 50% of its composition comes from waste coffee, supporting circularity and reducing the carbon footprint. As one of GreeNest’s Standardised Packages, KA-RZ demonstrates how everyday waste can be transformed into scalable, sustainable building solutions.
