Resumen

A fundamental objective to design a habitable space is to assure the occupants thermal comfort, considering anenergy use compatible with the activities developed in this space. The social housing does not fulfill this objective in Chile,due to: (1) Housing design does not consider this objective; (2) a high percentage of housing has a reduced area (smallerthan 50 m2 2  2  2 (40%) in Santiago, and 90 kWh/año·m2  (24%) in Punta Arenas.for refrigeration). Therefore, thermal comfort conditions are not achieved. On the other hand, the application of integral thermal control strategies produces important reductions of thermal loads, above to 45kWh/año·mforheating and 76 kWh/año·m ) with a high rate of occupation; (3) thermal envelope (walls, slabs on grade, ceiling and windows) has low thermal insulation capacity. (4) Chilean Building Code does not demand requirements of envelope thermal insulation,except for ceiling (since 2000). This produces a reduction of users? life quality and an inefficient use of energy resources inconditioning housing. The objective of this research was to evaluate the effect on heating and refrigeration loads of severalthermal control passive strategies, such as thermal insulation, windows orientation and size, and passive solar heating, inorder to establish recommendations for the design of social housing in Santiago, Concepción and Punta Arenas (heatingand/or cooling climates). PowerDOE, a building energy simulation software was used. The main results show importantheating and refrigeration loads for the housing without thermal control strategies (between 111 and 370 kWh/año·m
