Project Background

The design of the building answers to the implementation of an energy efficiency system oriented to reduce demand, improve the quality of work spaces and take a respectful stance with the environment.

The building is approximately 14,000 square meters. It has three offices levels, a vaulted-ceiling hall, an amphitheater, a casino and a café, surrounded approximately by 8,000 square meters of green areas and mirrors of water.
 

Strategies and Results


LEED NC Certification measures the sustainability of new constructions, measuring the impact on the environment, its surroundings, its future inhabitants and the energy consumption of its operation.

LEED certification is present in 129 countries worldwide, with over 38,000 registered projects and more than 6,500 projects already certified.

The TRANSOCEANICA BUILDING is the first construction in Chile to obtain the LEED GOLD Certification, through the NC (New construction) certification system.

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 spaces and take a respectful stance with the environment.

All the designers 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, weather and resources, projected a climate system based on the temperature of a deep well.

The system consists in circulating water by 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 to pre-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 at stable temperature, providing an indoors work environment of the highest standard.

This system, ground-breaking in Chile as well as in Latin America, needs to take precautions in terms of sun exposure, which is why the building counts with low thermal conductivity glass windows, a wooden lattice and exterior shades that are automatically adjusted as required by the building.

Other features related to the sustainability implemented in the building are efficient use of water, where part of the groundwater obtained is used to irrigate the park and for the mirrors of waters that include a natural system of aquatic balance. Additionally appliances and low consumption faucets are contemplated. All such considerations made to reduce the consumption of drinking water.

As for the landscaping project, almost only native species recovering the natural environment of this weather and location are contemplated. Such species require the minimum of water for their irrigation.

Already in operation, we have been able to verify that all the efficiency assumptions of the system were correct; and even without considering increases in the cost of energy, all the greater investment in those systems shall be paid between 2 and 4 years. Excellent news not only for Empresas Transoceánica but also for all new sustainable constructions in the country.
