Green Rubik

Location:

Bai Chay Urban Park, Ha Long City, Quang Ninh Province, Vietnam.

Type of Building: Residential Building
New / Refurbished: New
Status: Operational Stage
Year of construction: 2012
Gross Floor Area: 381.6 sq.m
Project-Description:

The building, named Dream House functions as a commercial and residential building with five floors and one underground floor. The first three floors are used as electronic appliance supermarket, and the last two floors are for residential purposes (penhouse apartment). The design objectives are aimed at creating a modern and dynamic building for commercial use cohesion with a friendly and cozy living space.

Located in the Bai Chay Urban Park, Ha Long City, Quang Ninh Province, Green Rubik Building has the total area of 381.6 sq.m and also in a convenient position which is near to main roads and a large intersection. The building has two main directions: East and South.

Passive Design Approaching:

Direction and Shading:
Located in the Bai Chay Urban Park, Ha Long City, Quang Ninh Province, Green Rubik Building has the total area of 381,6 m2 and also in a convenient position which is near to main roads and a large intersection. The building is both a commercial and residential building, while the first three floors are used for electronic appliance supermarket and the last two are for residential purposes. The design aims to create a modern and dynamic building for commercial use, and also a friendly and cozy living space.

The building structure is inspired by the simple square shape using glass as the main material just like the shape of coal- which is a symbol of Quang Ninh province. Because of being located at the corner of the road, the second floor of the building is rotated at a small angle as a rotating rubik’s cube. This idea creates an interesting and surprising view as well as visual impressions to enhance attractiveness of the nature of the building. The building looks like electronic equipment to boost the business strength of the owner.

With the direction of the building as shown above, all design solutions express a solid structure. The frontage and the rear are exposed by natural light in the East and West. Meanwhile cool wind comes from the Southeast. Therefore, its frontage, the rotation of the rubik’s cube helps to avoid being directly exposed to the solar radiation from the East and also creates shadows to cover the building in a day time. For the West direction, a solid partition wall combined with windows at a reasonable proportion (instead of glass like used in the frontage) is applied for heat resistance, but ensures daylighting.

Natural ventilation:
The building itself has a drawback on the directions (East and West), so natural ventilation is always considered as one of the top goals in the design process. The main object is creating a skylight in the middle of the building not only to provide good ventilation throughout the building but also acts as a vertically main connection inside the building.

Natural lighting:
The two frontages of the building use toughened glass walls not only for decorating but also to take advantage of natural light. Additionally, a large skylight greatly contributes to natural lighting and ventilation to other living spaces of the building.

Internal Green Space:
The system of green space and water surface for the above living space has differentiated the residential spaces from the commercial spaces and provided essential privacy for households. The space in the fourth and fifth floor make the penhouse is more quiet and natural despite of dynamics of the below commercial environment.

Besides the rotation of the Rubik’s cube to create shadows for the building, the 4th floor water surface helps to bring relaxation as well as comfortable feelings, taking in the Southeast wind and reducing natural radiation. Different voids inside the building not only makes the internal spaces more impressive but also forces the hot air to fly up the roof. Thermal insulation glass is used for the majority of the building to help reducing the cost for energy by a significant amount, especially for electronic commercial center.

Active Design Approaching

To overcome the challenges of the building in energy aspect, solar battery and solar water heater should be applied. Theoretically, from solar cells, light is transformed into electricity, DC power. After that, firstly, direct current power is leaded to the charge controller – a device automatically balances powers coming from solar batteries and one being charged for battery. And then, secondly, through the inverter, a 220V/50Hz standard alternating current is created to support other household appliances such as lighting bulbs, fans, TV, computers and pumps…

The use of solar power is to create various differences in the performance of the building, particularly the following objectives: Monthly saving electricity, independent electricity sources (less reliant on national electricity supply), environment protection, reduction on regional electricity load and continuous electricity supply, even in the case of electricity errors occur in the city.

The water supply system of the building is calculated carefully for two main purposes: offices and residential houses. Water is taken from the fresh – water distribution pipe of the city to proactively supply continuous water sources to the building through freshwater storage with the volume based on the above calculation.

Besides the combination of greenery and water surface for exterior and interior green space of the building, other used materials are popular and have high insulating capability, for example, toughened glass, plastic steel core doors, blocks, anti – alkali interior and exterior wall paint….
