Description du projet
Promouvoir des bâtiments à émissions quasi nulles dans les climats nordiques
Dans les climats froids, le remplacement du béton et de l’acier conventionnels par du bois permet de construire des bâtiments dont les émissions de gaz à effet de serre sont réduites. En combinant ces structures à des sources d’énergie renouvelables, il est possible d’obtenir des bâtiments à émissions quasi nulles (NZEB). Toutefois, l’un des défis consiste à maintenir les coûts de construction et d’énergie à un faible niveau. Le projet NERO, financé par l’UE, vise à concevoir et à démontrer la pertinence de modèles de bâtiments en bois économiques et économes en énergie pouvant être produits en série. Il recueillera pour cela des données sur 11 NZEB existants et préparera des estimations détaillées des coûts de construction et d’énergie pour six nouveaux modèles de démonstration. Le projet effectuera également des évaluations du cycle de vie de tous les NZEB, en comparant leurs performances pour identifier les domaines d’amélioration technique.
Objectif
The project develops and demonstrates nearly Zero Energy Wood Buildings design process and procurement models with reduced cost for large-scale use in the northern climatic conditions and on performance level of nearly zero and beyond. The project promotes large-scale market uptake of the developed nearly Zero Energy Wood Building applicable for construction industry design and procurement process. On site and nearby renewable energy system solutions are studied in order to provide real addition of renewable and energy production of on-site energy system. In addition to the nearly zero energy performance level, the project is also focusing on the performance level, which does beyond the nZEB level. Demonstration tasks on net-zero and energy-plus level will be also executed in the project. Analysis of the technical solutions including renewable energy systems will also reach to the plus-energy level because several nZEB buildings studied in the project will be plus-energy buildings.
The project develops and demonstrates methods and solutions, which significantly reduce the cost of new nearly Zero Energy Wood Buildings compared to the current situation. The project develops standard design process and procurement models for cost reduction for different building types for the Northern Europe climatic conditions. The cost reduction of the nearly Zero Energy Wood Buildings is shown in the project by means of the demonstration projects including both residential and non-residential single buildings. Wood buildings can result in 50 % reduced GHG emissions compared to conventional buildings with steel and concrete structures.
