New Energy Ratings for Greener Buildings

The Swedish National Board of Housing, Building and Planning (Boverket) proposes new energy performance classification rules for all building owners, introducing a new top class, A0, for "zero-emission buildings." These extremely energy-efficient buildings must not use fossil fuels, leading to updated energy performance certificates and new requirements for A0 classification, including systems adaptable to external energy signals, effective May 25, 2026.
