ABSTRACT This work shows the architectural design, technology features and thermal behaviour of residential and nonresidential low-energy consumption buildings. The buildings are located in the province of La Pampa, central Argentina, in a temperate climate; warm towards the NE and cold in the Centre, SE and SW, receiving high solar radiation in the pre-Andes region to the West. Glazing for solar collection in the principal functional areas facing to the North oscillates between 11 and 17% of the useful areas. All the studied buildings are massive, with exception of an Auditorium. The main thermal transmittance of the envelope is 0.45 W/m2ºC. Double glazing and hermetic carpentry were used to reduce thermal losses (U-value = 3 W/m2ºC). The Volumetric Heat Loss Coefficient (G-value) of buildings oscillates between 0.90 and 1.00 W/m3ºC.
