Project Summary
The building with its implementation of an energy efficiency system was designed to reduce demand, improve the quality of work space and respect the environment.
The building is approximately 14,000 m², with three office levels, a vaulted-ceiling hall, an amphitheater, an auditorium, a casino and a future cafe, surrounded by approximately 8,000 m² of green area and lakes.
Strategies and Results
LEED certification is present in 129 countries worldwide, with more than 38,000 projects and more than 6,500 registered and certified.
The Transoceanic BUILDING is the first construction in Chile to obtain the LEED GOLD Certification, through the certification system NC (New Construction).
Through various geothermal energy and energy efficiency plans, the building Transoceanic achieved one-fifth to one-sixth consumption of the energy demanded for a traditional building.
The building design is aimed at reducing energy demand, improve the quality of work space and adopt a friendly relationship with the environment.
All projects of the building were required to align and coordinate themselves to the climate project which was commissioned from the German office “Bohne Ingenieure,” who after studying our location, climate and resources, projected a climate system based on the temperature of a deep well.
The circulating water system is a closed system of capillaries (3.2 mm in diameter padded pipes) embedded in the ceilings of the offices, “cooling or heating” the space by radiation.
The same flow of water is used to pre-cool or heat the air which is injected into the building through a central air handler with a heat recovery system under the raised floor, and at a very low speed (2 meters per second).
The combination of these two systems, the capillaries and the air-injection system, ensure a 100% renewal of air and a stable temperature, providing a work environment within the highest of standards.
This system, pioneered in Chile as well as in Latin America, in terms of sun exposure, must take precautions, which is reason why the building uses low thermal conductivity glass windows, lattice wood and exterior shades that are automatically adjusted according to the building’s requirements.
Other features related to the sustainability implemented in the building are those such as: the efficient use of water where part of the groundwater is used to irrigate the park and shallow water pools (ponds) that include aquatic life. As well as, appliances and low consumption faucets. All considerations were made to reduce water consumption.
As for the landscaping project, you can observe native species unique to this climate, environment and location, together with a minimum water requirement for irrigation.
Now almost a year in operation, we can verify that all efficiency system assumptions were correct and even without considering increases in the cost of energy. The majority of all investments in these systems will be paid between 2 and 4 years; excellent news not only for the Transoceanic Company, but for all new sustainable constructions in the country.
