GEMPOL MARKET

The 1st and 2nd floors of the building are used mostly for commercial areas. All 3rd and 4th floors are used for residential areas to ensure residents' privacy. Residential openings lead outside the site, to minimize excessive sun exposure and rainwater ingress, there is a slidable bamboo facade that can be shifted as needed. The terraced form is a response to the existing trees which are not disturbed and used as space shade. On the 3rd floor and rooftop there is an open communal area that can be used for residents to relax and interact with each other.

BUDGET HOTEL

As a response to the west-east orientation, the hotel facade is made in the form of tilted vertical fins to minimize excessive sun exposure to hotel room units. Building facades also use bright colors that counteract the effects of black body radiation. Because the location of the site is close to the campus and there are many students around the site, the budget hotel design is aimed at the student market target. Apart from places to stay, this hotel emphasizes the design of cafes and coworking spaces which are the lifestyle of today's students, especially at ITB, where students often study in groups and do assignments at cafes.

Clean Water Distribution System

The supply of clean water for the water needs of the Budget Hotel building comes from the PDAM. The need for clean water in Budget Hotel buildings is calculated from the estimated number of building users. The number of people in the building is estimated at around 300 people. A water tank is placed on the rooftop to provide water distribution by utilizing gravity to every room and toilet that needs clean water. With an estimate of the need for clean water that must be provided at a standard of 150 liters/person/day, the need for clean water is obtained :

Typical Number of Floors : 6 Floors

Number of Room Units per Floor: 24 Room Units Number of Occupants per Floor : 50 People

Total Number of Occupants of the Building: 300 People

So, the need for clean water: 150 x 300 = 45000 liters per day

Tanks available on the market have a maximum capacity 8000 liters, so 6 water tanks are needed on the rooftop to meet the needs of clean water of the building.

Dirty Water Distribution Syste m

Dirty water channels from the toilet in the room unit are combined every two rooms to save on pipe costs, save space, and simplify maintenance in the case of damage. This dirty water channel is then channeled to a septic tank to be treated first before being channeled to the city sewer. Determining the dimensions of the septic tank also depends on the number of occupants of the building. The estimated volume of dirty water coming from the toilet is 75 liters/person/day. So that the re quired volume of the septic tank is: 75 x 300 = 67,500 liters.

The required dimensions of the septic tank are:
 7.6 m x 3.3 m x 2.7 m = 67,716 liters.

The height of the septic tank is given an additional 30 cm of air space, so the final dimensions of the septic tank are:
 7.6m x 3.3m x 3m.

Vertical Transport System

The vertical transportation system in this Budget Hotel building uses elevators and stairs. There are two elevators located in the middle of the building aiming to make it easier for visitors to access the elevator. Each elevator has dimensions of 1100 x 1400 cm with a capacity of 8 people.

To facilitate housekeeping and other service work, this hotel has dumbwaiter system that connects the laundry and housekeeping rooms on each floor. There is also separated dumbwaiter for waste that also connects to the housekeeping rooms.

Fire Protection System

Based on the technical requirements for building fire protection, namely "Floor area of ​​ 900 m2<area<2,000 m2 there are at least two units of fire shaft." Typical floor area in this budget hotel building is less than 900 m2. Therefore, the number of fire shafts in this building is 1 unit. This fire shaft consists of an emergency stairwell which is built with a fireresistant wall for a minimum of 2 hours, and a passenger lift which can also be used as a firefighter lift.

The placement of the fire extinguisher shaft in the middle of the building aims to meet the requirements for a maximum service radius of 38 meters for each shaft and there is an exit that leads directly outside the building.

EXIT EMERGENCY TO THE OUTSIDE OF THE BUILDING

The building entrance is made in black with high ceilings which contrasts with the entire facade to emphasize the function of the entrance and give the impression of height.

Petalora is a pavilion with a span of 30 meters made of hollow steel structures with the application of active vector system.

The shape was inspired by the shape of flower petals and became the idea for the name Petalora, namely "petal" and "flora".
