Energy-intensive building

Project: Palm Tree Residential Area, Ecopark, Hung YenBuilding investor: Viet Hung Company (VIHAJICO)Architecture designer: Kume SekkeiTotal land area: 40,100m2Ecopark 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.

Contracting method

General Contractor

If you had to do it again?

Create a place for PV systems to use renewable energy for some part of the buildings such as hot water heating

Building users opinion

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.

Energy consumption

Primary energy need : 16,30 kWhpe/m².year
Primary energy need for standard building : 43,50 kWhpe/m².year

Calculation method : Other

Breakdown for energy consumption : Lighting,coolings , fans, hot water heating, other appliances (we do not have specified different energy use)

Envelope performance

Envelope U-Value : 1,39 W.m^-2.K^-1

More information :

Non-baked brick, low U-value for better insulation concrete (light coloured painting) + plasterboard
(Uvalue is ~1.39 W/m2K)

Building Compactness Coefficient : 0,01

Real final energy consumption

Final Energy : 40,00 kWhfe/m².year

Real final energy consumption/m2 : 40,00 kWhfe/m².year

Year of the real energy consumption : 2 015

Systems

Heating system :

No heating system

Hot water system :

Individual electric boiler

Cooling system :

Others

Ventilation system :

Natural ventilation

Renewable systems :

No renewable energy systems

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

Solutions enhancing nature free gains :

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.

Real energy cost/m2 : 2.26

Real energy cost/Dwelling : 256

Biodiversity approach

Urban environment : 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. Ecopark offers a comprehensive environment where communities live, work, and relax. Creating opportunities for personal and professional growth, Ecopark is a place where families can live healthy, safe and comfortable lives and professionals can seek quality employment. Residents can enjoy a modern lifestyle within their resort-like community, while visitors can immerse themselves in the relaxing ambience of Ecopark’s lush, picturesque landscape.

Reasons for participating in the competition(s)

Palm tree residential buildings located in Ecopark area, which has strongly friendly environmental design. The building design has been considered with several passive strategies such as: - Building envelope with U-value of wall and roof meet the energy efficiency building code in Vietnam.- Shading devices systems are installed on the windows. - The building shapes are considered carefully to optimize the natural ventilation and daylighting:+ Natural ventilation for all main function spaces/auxiliary spaces+ Daylighting for all main function spaces/auxiliary spaces- Vegetalisation of the surroundings for reducing heat island effect as well as permeable surface- Water Efficient equipments has been installed by tenants- Evaporated cooling by water surface surrounding the area The green and eco strategies for residential buildings are always more difficult than the other type of buildings. The buildings which are using in this period of time not only to save energy but also have to meet the requirement of tenants in the modern life.
