Examples in Chile of Sustainable Buildings
With Dr. Ing. Luis Ebensperger the GBTool system has been applied to assess the environmental performance of the building that are described below, which were presented at the internacional conferences indicated in each case:
Edificio VARELA
Presented by Norman Goijberg at Sustainable Building Conference, sb’00, Maastricht, Holland, 2000
Location: Av. Del Valle 662, Ciudad Empresarial, Huechuraba, Santiago
Architect: Horacio Sotomayor
Energy Design: González & Bustamante
HVAC: Termofrío
Gross built area: 5.111 m2
Overview:
Climatization by water, that uses the natural temperature of the ground, by heat pumps, cooling by evaporation taking advantage of the temperature differential between day and night (summer), heat exchangers (fresh air-extraction), maximum natural light, plants that require minimum irrigation, lighting with systems and equipments for energy efficiency, occupation sensors.
Results
Resource Consumption – Energy
The consumption of the building operation had a savings of 72% regarding a reference building:
Consumption Varela Building = 169 MJ/m2 /
Consumption Reference Building = 594 MJ/m2
Potable Water
Potable water consumption has 60% savings regarding a reference building.
Environmental Loadings
Green House Emissions of all the energy used over the life cycle of the building is 65% of the reference.
Headquarters Building ISAPRE CONSALUD
Presented by Norman Goijberg at
Sustainable Building Conference, sb’02, Oslo, Norway, 2002
Location: Pedro Fontova 6650, Huechuraba, Santiago
Architects: May & Soler, Santiago; dell’ Aquila & Voerzio, Italia
Energy Design: SUNNA, Dr. W. Stahl, Freiburg
HVAC: Gormaz & Zenteno, Santiago
Built Area: 20.567 m2
Overview:
Climatization by air, that uses the natural temperatura of the ground, through pipes buried Ander the garden, vertical air distribution through structural steel columns and horizontal through raised floor, natural light, shading of north windows, natural ventilation in gym zone.
Results
Resource Consumption – Energy
The consumption of the building operation had a savings of 57% regarding a reference building:
Consumption Consalud Building = 337 MJ/m2 /
Consumption Reference Building = 594 MJ/m2
The embodied emssions of the materials (steel structure), over the life cycle of the building, is only a 46% of the reference.
Green House Emissions of all the energy used over the life cycle of the building is 62% of the reference.
New Airport Región de la Araucanía, TEMUCO
Presented by Norman Goijberg at
Sustainable Building Conference, sb’05, Tokyo, Japan, 2005
Division of Airports, Ministry of Public Works, Transport and Telecommunications
Consultants:
General Contractor: ARCADIS GEOTECNICA
Master Plan: Rodolfo Chávez, Architect
Architectural Design: Juan José Bas, Architect, GEOCIUDAD
Sustainable Building Consultants: Norman Goijberg and Horacio Sotomayor, Architects
PROPOSAL FOR SUSTAINABLE BUILDING DESIGN
AIR
• Openings for natural cross ventilation
• A central patio with vegetation to stimulate climatic stabilization, humidification and thermal convection. Adding oxygen and consuming CO2 from the indoor environment.
.
SUN AND NATURAL LIGHTING
It is privileged:
• Solar orientation, north openings.
• Use of materials that
aid thermal gain.
• North openings.
• Double pain glazing and fixed or mechanical shading
• Sun-roof lighting through sky-lights or light-ducts.
Results
Energy savings is 43.8% regarding a reference building.
