Energy efficiency in multi-family residential buildings in Latvia. Cost benefit analysis comparing different business models

摘要

Energy Performance Contracts (EPCs) are very seldom used in the residential sector, especially for extensive renovations of multi-family or apartment buildings. Only up to 10 % of energy service companies' activities are targeted in the sector. A cost benefit analysis was carried out to compare different renovation business models. It was proved that EPCs can be applied for extensive renovations reducing the annual costs for residents and ensuring safe, comfortable and sustainable housing.
