- The Passivhaus Standard is a construction concept based on affordably achieving the best indoor conditions with the lowest energy demand. If adopted, it could contribute to fulfil the lack of regulations in energy and comfort performance in Colombian dwellings that the current sustainability laws mandate. The Standard has been applied in warm regions mostly throughout the Mediterranean.This work intended to study its applicability for social housing in tropical climates, specifically four Colombian cities with different average energy demands and number of occupants per household and diverse climatic conditions.The work identified and described a reference building based on an average ‘good practice’ social housing project product of the current Building Regulations. It was modelled in the Passivhaus Planning Package (PHPP) to analyse its performance in the four cities. The results showed that the thermal performance of the building envelope is better than expected due to favourable climatic conditions in most of the cities, although it needs improvements. Even if primary energy demand is lower in the four cities than the maximum allowed by the Standard, it would be considerably high for dwellings without mechanical heating or cooling.The improved models showed that adopting passive strategies according to local climates reduced daily temperature swings and increased indoor comfort. Applying energy efficiency measures such as solar thermal DHW and more efficient fridges and lighting decreased primary energy demand significantly to less than a half of the maximum allowed. The Standard would be applicable in tropical climates even within the budget limitations for social housing in Colombia, although not exactly in the same way as in central Europe. Local circumstances and passive strategies must be taken into account to feasibly achieve the Passivhaus Standard in Colombian social housing.
