PHI publishes research on passive house in tropical climates

The Passive House Institute has published a new study that looks at designing passive buildings for tropical climates. The study concludes that the key design criteria for such buildings include,"a very airtight building envelope, 10 to 15 cm of insulation, solar control glazing, fixed external shades for the windows and ventilation with both heat and energy recovery".
