TONG CHIA SIN 1101A12324 Tutor: Ms. Fadzwin
DESIGN ANALYSIS Programme Introduction The proposed programme is a Multimedia Performing Arts Center. The site is surrounded by residential areas, schools and other institution. The potential crowd that the multimedia performing arts center could pull in is considerably large as there are little source of entertainment in the immediate surroundings. The people lacks a place where like-minded individuals of the visual arts could gather and share their work. This in turn will bridge the gap between the younger and older generation. Hence, the addition of a multimedia center should be prioritized because it adds to the excitement and appeal, and illustrates concepts in a way that static information cannot because seeing and listening is believing. With a physical platform for the multimedia to be shared via projections, individualized learning and a broader view of the world can be encouraged as it makes an application or program more interactive and user friendly. Other than the broadcasting of local work onto the walls of the building, the proposed programme invite in softscape to act as a catalyst to activate the public realm space. With an influx of people into the proposed building, the current dormant site will once again see its glory days.

Project Objectives The aim of the project is to bring life to the site. The proposed building, when successfully completed, will be a beacon of light on the dormant site, attracting people all across the district to come together once again to witness the power of a physical social media platform. The project will reconnect the street level on the front, to the back where a beautiful riverfront amenity awaits. Programme Provision • Provide gathering space for the community and patrons of the building • Provide comfortable and suitable areas for outdoor video projection • Light after Dark, to revive the nightlife at Jalan Ampang
Design Provision • To provide a building which is user-friendly and accessible to all age group, including the disabled user group. • Combine the natural and built world for a more holistic experience • Rooftop garden provided for leisure purposes and public gatherings • Cafeteria facing the promenade for patrons to enjoy riverfront views • Revitalise the back alley portion by visually connecting the two scapes
Site Introduction The proposed site is situated in Jalan Ampang, a busy main road leading to Menara AIA. Our site is located in a urban context, surrounded by high rise institutional and residential buildings. However, it is also sandwiched between the Bukit Nanas Forest Reserve and Klang River where it is quite polluted due to negligence by the community. Riverfront amenities is severely under-developed although there is easy access to public transport to and fro the site. For instance, Dang Wangi LRT Station and Masjid Jamek LRT Station are walking distance from proposed site. There are multiple bus stops around the site , with one just opposite the proposed building. Arriving at the site is definitely not as issue. From the S.W.O.T analysis, it is also observed to be rather well shaded throughout the day.
SITE ANALYSIS Climatic Data
The climate surrounding the area is identifies as the tropical climate which is relatively the same all over Malaysia. With the strong linear characteristics of the site, it is challenging to solve issues of orientation and maximization of natural ventilation.

Due to the linear nature of the site, there are a few challenges as to how best to orientate the site to reduce solar hear gain and maximise natural ventilation. Despite having the flexibility to demolish the entire site and it’s existing buildings, the pocket of area that was chosen for this design took all design and environmental factors into consideration. To maximize space, the design utilizes most of the space within the set back line without neglecting the importance of a public realm space. The orientation of the buildings is a juxtaposition on the site. The linearity being the site, and the vertical blocks being the proposed building. The building projects to the back and brings users closer to the river front. With this being done, the surface area of the building on the West is largely exposed to natural sunlight, whereas on the East, sunlight hits the corners of the buildings instead. The issue of sun exposure will be further resolved with the appropriate sun-shading devices. This will addressed in the report as solar heat gains concerns human comfort levels as a whole and achieving optimal internal thermal comfort (especially in the tropical climate) is an aim that many architects try to achieve.
SITE ANALYSIS Solar Control Exposure to long hours of sunlight is minimised on site as it is surrounded by highrise buildings (Capsquare Residences) and a very dense forest reserve on the front. However, the proposed building still gets most of its sun exposure during 12PM where the sun ray is directly hitting the building from the top.

The fact that the building design incorporates visual permeability between the outside and inside means a lot of glass is used in the design. From the sun path diagram, it can be seen that the Western part of the building gets the most sun if Capsquare Residences cease to exist.
To address the unlikely chance that Capsquare is demolished, there are a few design feature introduced to the building to reduce thermal heat gain in the building. There is a metal screen which visually dresses the structure and protects it from environmental forces. As can be seen above, there is a projector screen to allow for open screening to the public. and has a dual function as a sun and rain screen for the internal spaces.
On the Eastern side, extra sun protection is taken into consideration with the incorporation of a double wall to not only act as a noise buffer (building faces main road that is prone to noise pollution during after-school hours), it also minimise heat gain while still allowing considerable about of light through the slits on the wall.
SITE ANALYSIS Ventilation
From the annual windrose diagram retrieved from the Malaysian Meteorological Department, it can be observed that prevailing wind comes mostly from the South South East direction. With an environmentally conscious approach to the building, wind “tunnels� are created to increase the speed of wind, and thereby promoting natural ventilation into the building.
The issue with the site is that the incoming wind could be blocked by the nature reserve on the front. With this consideration, there are outdoor water decks and balconies to allow for wind exchange. With the combination of these two, the Multimedia Performing Arts Center gets a healthy exposure to natural ventilation to keep the building relatively cool without depending much on mechanical needs.
Balconies to allow for wind exchange

Cross Ventilation Air inside a building needs to be replenished regularly. Stale air can hold moisture and cause mold. It can also smell bad, and make a building uncomfortable to be in for an occupant. Without a supply of new air, sources of irritation and allergy in the air, such as dust or hair, can also adversely affect health. It is therefore important to ensure a rooms are well ventilated. In this case, the rooms have openings on the opposite side of each other. Wind provides outside air with more force than the air inside the building. Both of these sources of pressure tend to drive the air into buildings. The air comes in through the entrance, which is a window or vent on the side of the building that faces the wind. Where cross ventilation comes into play is areas where the incoming air can displace the interior air and push it out of the building. Stack Ventilation
Stack ventilation is another passive ventilation that use air pressure differences due to height to pull air through the building. Lower pressures higher in the building help pull air upward. uses temperature differences to move air. Hot air rises because it is lower pressure. For this reason, it is sometimes called buoyancy ventilation. To allow adjustability in the amount of cooling and fresh air provided by stack ventilation, the inlet openings are adjustable with operable window. Stack ventilation is combined with cross ventilation.
SITE ANALYSIS Rain Water Harvesting
Malaysia is blessed to have a high rain fall throughout the year. A good design strategy that works well in the Malaysian climate is to incorporate a rain water harvesting system. The idea behind the process is simple. Rainwater is collected when it falls on the earth, stored SG. and utilized at a later point. Utilizing the rainwater KLANG harvesting system provides certain advantages to the community. First of all, harvesting rainwater allows us to better utilize an energy resource. It is important to do so since drinking water is not easily renewable and it helps in reducing wastage. Secondly, rainwater is free from many chemicals found in ground water, making it suitable for irrigation and watering the trees at the public realm space surrounding the proposed building. On top of the proposed Multimedia Performing Arts Center, there is a large roof garden that is a passive design feature to reduce heat gain on roof. Having a roof garden requires maintenance as well as water supply to water the plants. It is only appropriate that the collected water from the system can be used to water roof garden other than plants at ground level. This design feature will also help in reducing water bills in the long run.
