Energy-intensive building

Ecolife Capitol’s three high-rise residential towers introduced over 630 green apartments to the housing market in Ha Noi, Vietnam. To maximize energy savings and ensure occupant comfort, each of the apartments in the development are designed to maximize natural ventilation and feature low-flow plumbing fixtures, LED lighting and low-E double-glazed windows.

Ecolife Capitol was built by Capital House, a real estate investor dedicated to improving the resource efficiency of commercial and social housing through the use of energy-smart architectural design. Ecolife Capitol received final EDGE certification from SGS Vietnam.

    A green project is a project that can not be green or green, but must be green, to create an ecological environment with fresh air, thereby creating comfort, do Increase happiness index for residents and longevity of people.
    With the design of this green - sustainable - environmental friendly motto, EcoLife Capitol was built from nature-friendly materials in harmony with the landscape which do not pollute the environment and save maximum power sources. At EcoLife Capitol, work surfaces allow sunlight through subtly arranged spaces. Spaces and the architecture ratio are researched in terms of sun and wind direction to reduce the impact of climate and strong light. Rooftop greeneries provide oxygen and contribute to a comfortable living space.
    The residents of the EcoLife Capitol have seen the real value of the project in enhancing health indicators, good ecological environment, and significant energy savings
