The document summarizes the assessment of entries for an ecological building competition. It assessed criteria such as energy performance, material efficiency, and construction costs. The best performing entries were Apila for energy efficiency and lowest life cycle carbon emissions, and Solaris for material efficiency. Overall, Apila had the best balance of ecological sustainability and economic feasibility, as it achieved low carbon emissions and construction costs without major technical risks to implementation. Solaris and Valaistus also performed well but had some challenges with maintenance and feasibility of technical solutions that increased economic and sustainability risks.
