High-Rise Apartment

Project idea

The building is a high-rise residential complex that is situated in Addis Ababa, Ethiopia, near Mexico, the city's bustling business district.
The way Ethiopians coexist in harmony and togetherness served as inspiration for the architecture of this high-rise residence. The design is an example of traditional Ethiopian dwelling and incorporates the horizontally built "gebi" (front yard) and "guaro" (backyard) concepts. And with the idea of residing together, place these characters vertically in high-rise apartment buildings. Using circular shapes to convey the oneness and attachment of the Ethiopian people, for example, is one approach to enhance the rich and beautiful Ethiopian tradition of coexistence and merge it with modern lifestyles.

Project description

The building is 148 meters long, has 37 levels, and a floor height of 4 meters. There are 105 apartment units and 477 underground parking spaces on the tower podium, which is allocated for commercial use and other facilities. Additionally, the 8-meter distance between the podium and the tower created a sense of openness. The podium's roof top is also intended to be used for multipurpose events like weddings, sedeqas, playgrounds, and recreational areas to celebrate various ceremonies.
The tower has 30 stories and three different types of apartments on the first 26 floors (7 to 26). The duplex flats are on floors 27 through 35, and the penthouse is on the last floor.All typologies of the typical apartments have the concepts of a frontage and a backyard, and there are alternatives for 1 bed, 2 bed, 3 bed, and 4 bed room typologies. The kitchen door leads to the backyard, which is connected to it. The frontage and backyard of the duplex apartments are joined, and the frontage portion is opened down to create an open environment. The duplex apartments come in two different typologies with two and three bedrooms. The design approach was to design guaro and gbi to promote social contact, a sense of the earth, and a green living environment.
The location for the story is a historic place next to the Lombardia building. Utilize the shade and roof access to connect the building to Lombardia
According to the site's topography, there are two ground floors and entrances, the lower ground and the ground, both of which are used as parking entries and exits. The emergency parking lot is located in front of the main entrance and has surface parking for emergency vehicles. At the entryway, there is an area that is open down so that people can readily understand the commercial and other service areas.
Municipal and subsurface water are the building's main water sources. The underground water is purified using a filtration system and stored in a container in the basement before being pumped to the roof and put into two distinct tankers. The first tanker carries cold water, and the second has a backup electrical boiling system and a central solar heating system. Then, utilizing separate pipe lines and gravity, water from each tank (cold and hot) will be sent to each floor's rooms and floors. Each floor will also have a controller.
Additionally, the top levels of the building will have their own pipelines and pumping equipment. Another tanker with its own pump will also be available in the basement for use only in emergencies. Gray water from each room and the laundry will be gathered in the basement, purified there, and then piped into each room for just flushing purposes.

Technical information

It is impossible to open windows above the 16th floor due to Addis Ababa’s wind pressure. In order to get passive natural ventilation and reduce wind intensity, double glazing façade systems are used. The glasses each have their own openings, with the internal glass having bottom and top openings to allow air to enter the building and exit it, while the external glass has a center opening. The internal glazing will also have greenery close by to assist lessen excessive wind power and provide fresh air.
Additionally, Fresh air is drawn from the atmosphere at the roof's top and sent to a cooling tower where it is filtered before being transferred to a chiller for storage. The air will be distributed into each area from the chiller. The heated air will travel up and into each room through a separate pipe line, and the cold air will finally drain into an exhaust system in the basement boiler.
For duct air removal, the building features two systems. The ground floor is where duct air from the basements is gathered and released through exhaust air. Additionally, duct air gathered from the structure (tower) will be released at the roof's top using a different exhaust air system.
Structural system: pile foundation, digrid, post tension, core, and frame. The diagrid in the tower crosses itself in 3 meters, and then transfers the load to the foundation in 6 meters as it approaches the podium.
The shooter, HVAC lines, and stores are all connected, and the building's core is located at the central vertical circulation. The vertical circulation has six lifts, the first of which is accessible for floors with odd numbers of floors and the second for floors with even numbers, as well as one one-way fire escape. The fourth lift is reserved for the podium and the third lift goes to the regular floor. The fifth and final elevator, which is accessible from all levels, is for duplexes and penthouses. One sort of shooter is used for laundry, and the other is used for trash.
