1 3 HOUSE DESIGNS OF 140m² A modern concept for energy efficiency ENERGY EFFICIENCY AND ENVIRONMENTAL QUALITY Minimum Energy Consumption 84% energy heating savings* * According to a home fulfilling thermal regulations. See graphic 1. BUILDING FOR THE FUTURE

2 First Chilean housing project with the world s highest standards in energy efficiency. Housing applying the recognized Passivhaus standard. Puerta del Sol housing project combine high comfort levels and extremely low heating energy consumption. Passive components as high thermal performance windows, high thermal insulation thickness and low power consumption heat recovery ventilation system. Each home is an effective contribution to environmental protection. PUERTA DEL SOL SALES ROOM Monday to Saturday from 11:00 to 13:30 and 15:30 to 19:00 hrs. More information at Av. San Martin intersection Av. Botrolhue HOUSE CHARACTERISTICS Comfortable: Puerta del Sol houses have thermal envelope and windows that allow maximum energy performance, ensuring minimum demand for heating in winter and high environmental quality indoor air. Sustainable: The enenergy efficiency of these homes reduces to zero CO2 and pollutants emissions into the atmosphere due to heating systems. Innovative: The concept of applied energy efficiency in this project is a modern alternative that opens new perspectives, providing a great solution to Temuco s decontamination. Simple: No need of greater knowledge by users.

4 FUNDAMENTAL CONCEPTS Improved thermal insulation reduces heat loss resulting in higher interior temperatures in winter and lower temperatures in summer (using passive cooling strategies by night). EXCEPTIONALLY HIGH THERMAL INSULATION Thermal bridge free Puerta del Sol thermal envelope desingn allows to minimize energy losses and prevent condensation on cold days. THERMAL BRIDGE FREE BUILDING Pencil rule: Vapor barrier (red) and thermal insulation (orange) should be able to be drawn uninterruptedly around the envelope. In filtration entre 0.6 a1 ACH / h AIR TIGHT ENVELOPE A properly insulated window improves thermal comfort as it allows to maintain an average temperature about 17 C between its internal surfaces. Even in winter, in extreme conditions, shows no temparature drops on the window surface. The U value for windows must be less than 1.4W / m²k, including frames and glazing. Table 1. CORRECTLY INSULATED WINDOW FRAMES AND LOW-E GLAZING. AIR VENT INJECTION EXTRACTION OUTSIDE AIR INLET The ventilation system of these houses has a fundamental role, providing clean air, filtering pollen and dust, reducing humidity and odors. Opening the windows to achieve this would generate large energy losses and indoor temperature variations. The heat recovery system efficiency is above 85% consuming less than 0,45W/m³/h. COMFORT VENTILATION WITH HIGH-EFFICIENCY HEAT RECOVERY SYSTEM

5 HEAT RECOVERY VENTILATION SYSTEM The house has a permanent renewal air system with low electricity consumption for energy optimization, which heats the inlet air as needed and recovering more than 85% of the heat from the stale extracted air. Efficient distribution system to incorporate air renewed through bedrooms and living room, extracting from bathrooms and kitchens, providing constant air circulation for a comfortable and healthy indoor climate.

INDOOR ENVIRONMENTAL QUALITY Thanks to its entry filter systems minimizes particulate matter and pollen, providing a healthy indoor environment for people suffering allergies or other respiratory diseases.

6 ANNUAL HEATING ENERGY DEMAND Annual heating demand according to regulations. German and Chilean regulations evolution. Graph 1. Chilean Thermal Regulation German Thermal Regulation New PDA Temuco y P. Las Casas Passivhaus Certification year Source: EEChile Thanks to the exterior thermal envelope, thermal bridge free window and door openings, junctions and terraces, high thermal performance glazing (U value lower than 1.4 W/m²K), control over solar gains and air tightness with active ventilation system, a house with minimal energy demand is achieved. The annual energy demand for heating is 20 kwh/m², considering the appropriate house operation. A house that meets the thermal regulations, demand annually for the same comfort conditions 130 kwh/m². Puerta del Sol houses save more than 84% of the required annual heating energy.
