Abstract

In the light of the ambitious climate goals, the energy efficiency scope is gradually shifting from an individual building to a broader range – urban block, neighborhood, district, and city. Smart cities and communities show a significant potential of reaching energy efficiency goals. This study presents the results of a newly developed demand‐supply energy flow model. The model simulates the energy demand and supply dynamics of a traditional building block in the historical center of Riga, the capital of Latvia. The authors analyzed 12 different scenarios applying four factors – energy efficiency, renewable energy technologies, waste heat recovery, and electricity storage in electric vehicles.
