Project Description

Project: Palm Tree Residential Area, Ecopark, Hung Yen Building investor: Viet Hung Company (VIHAJICO) Architecture designer: Kume Sekkei Total land area: 40,100m2 Ecopark blocks were designed in accordance with the functional city model with full utilities. The buildings are covered by trees surrounding and water ponds, which are combined harmonizing between citizends and nature. The investor also create new bus lines for citizens and visitors. So that the distance between ecopark and city center may be not a trouble for citizens to come.

Climate Analysis


Hanoi has a warm humid subtropical climate with plentiful precipitation.The city experiences the typical climate of Northern Vietnam with 4 different seasons. Summer, from May until August, is characterized by hot and humid weather with abundant rainfall. September to October is fall, characterized by a decrease in temperature and precipitation. Winter, from November to January, is dry and cool.The city is usually cloudy and foggy in winter. The averages rainfall is 1,680 millimetres (66.1 in) per year and the most precipitation is from May to September. The average temperature is 23.6°C (74°F) with a mean relative humidity of 79%.The highest recorded temperature was 42.8°C (109°F) on SMay 1926 while the lowest recorded temperature was 2.7 °C (37 °F) on January 1955.

Design Approach


The blocks are located as zigzag shapes; therefore, the apartments have daylighting, good and diverse views. Orientation of buildings is considered clearly, which does not face to East or west and may utilize the prevailing wind from the South and the South-East. Ventilation gaps/clefts are installed surrounding the buildings are to get more daylighting and ventilation into auxiliary space (restroom, kitchen...). Therefore most of their spaces have natural ventilation and daylighting. Garden is in the middle of blocks with ponds for evaporative cooling

Trees are grown for shading and water ponds are installed for evaprative cooling. Reducing the concrete surface by weed area is to increase permeable surface. More weed and trees surface helps to reduce heat island effect. Water ponds also reduce the heat by 2-3°C sorrounding the buildings.

Construction complex comprises 13 dwelling units. The building complex is recognized with the following items: + Sustainable site: arrange the building according prevailing winds, with water ponds, for optimizing ventilation and evaporate cooling; + Friendly environmental material with non-baked materials; + Solid waste control; + Utilizing renewable energy for street light. And using energy efficiency appliances; + Passive strategies for building form, and envelope; Passive design approached: 1 - Technical roof for insulation; 2- Non-baked brick from recycled material with low U-value for better insulation, (mova motar); 3 - Balcony as solar shading in some spaces; 4 - Vegetalisation of the surroundings; 5 - Water Efficient equipment; 6 - Evaporated cooling; 7 - Natural ventilation for all main function spaces/auxiliary spaces; 8 - Daylighting for all main function spaces/auxiliary spaces;

Special Feature


The blocks are located as zigzag shapes; therefore, the apartments have daylighting, good and diverse views. Ventilation gaps/clefts are installed surrounding the buildings are to get more daylighting and ventilation into auxiliary space (restroom, kitchen...). Therefore most of their spaces have daylighting. --> Daylighting for all main function spaces/auxiliary spaces

Water Efficient equipment such as toilet/ Water recycle system

The blocks are located as zigzag shapes; therefore, the apartments have daylighting, good and diverse views. Orientation of buildings is considered clearly, which does not face to East or west and may utilize the prevailing wind from the South and the South-East. Ventilation gaps/clefts are installed surrounding the buildings are to get more daylighting and ventilation into auxiliary space (restroom, kitchen...). Therefore most of their spaces have natural ventilation and daylighting. Garden is in the middle of blocks with ponds for evaporative cooling. Guidelines for wind flows: + Tower only, no podium to allow more channels for air to move at ground level + Staggered tower arrangement across park. + Taller tower along edge of park to accelerate air movement through wind tunnel effect.

The application of energy efficiency equipment and passive desing reduces the energy use for cooling system, it leads to the money saving for electricity

Non-baked brick, Which just complies with EEBC 09:2013/BXD Energy efficiency building codes; Using balcony as shading, and some short horizontal shading

To avoid the use of air-conditioning, several passive strategies are used : insulation roof, cross ventilation by ventilation clefts/gaps, reduce heat, orientation according to prevailing winds. The large and dense garden and vegetalisation of building access permit to limit heat accumulation. Artificial lights are reduced to accurate requirement. And water ponds for evaporate cooling. The buildings with ventilation gaps/clefts surrounding can get more daylighting and ventilation into auxiliary space (restroom, kitchen...). Therefore most of spaces have natural ventilation and daylighting.

Building Material


Reinforced concrete

Concrete

Non-baked brick, low U-value for better insulation concrete (light coloured painting) + plasterboard

WWR is about 30%

Installed by occupants

NA

Technical roof with non-HVAC system; Concrete + insulation+ plaster void+ plasterboard/ And technical roof without HVAC

Balcony as solar shading in some spaces

Energy systems


Installed by the occupants

solar energy lighting

Fans are installed by occupants

Inverter air-conditioning, installed by customers

installed by investors

Controls : timer switch according the sun for exterior lighting

Domestic solar water systens are installed in only private houses but not in the highrise buildings. Street lights use solar energy.

Lessons Learned


Palm Tree Residential Building is a modern residential area with smart design, open spaces and effective utility service. The project is surely an optimized choice for families.

The building with great infrastructure and landscape surrounding. The outdoor activities are often performed here to attract people to live. However, it is quite far from city center.

Service maintenance is quite good until now.The blocks are in a new eco-residential area with full infrastructure. It is far from city center; however, the bus is convenience to go. The citizens can also use their private vehicles for travelling.
