Modern apartment projects boast heating bills three times lower than Soviet-era houses, yet even 2000s constructions lag behind today's energy efficiency standards. Latvia's Cabinet of Ministers endorsed energy efficiency calculation methods three years ago, demanding primary energy efficiency for new buildings, emphasising renewable energy use. In fact, Housing Department Director Mārtiņš Auders highlighted the importance of renewable sources like solar energy and heat pumps in achieving efficiency. With heating costs as a benchmark, buildings are classified from A to F, with new constructions mandated to meet class A. 

Engineer Andris Vulāns noted deficiencies in buildings from both Soviet and post-2000 eras, urging better construction practices. The need for energy audits in old buildings is highlighted, alongside evolving regulations for energy-efficient constructions and considerations for buildings' long-term lifecycle.
