1.0 PROJECT INTRODUCTION The module emphasizes the role of building technology and sustainability in architectural design through an analysis and evaluation of a complex building or group of buildings. It addresses architecture as an integration of the environment, technology and building. These three factors are considered as holistic components of architectural design, which may be critically assessed with theories. Specific topics of environment and technology are isolated out for investigation. The module equips students with knowledge of building science and skills in the use of information and digital technology to inform design and to support the design resolution of students’ Architectural Design Thesis, particularly with respect to architectonic and technological aspects. This project is an integrated project with the Urban Design Studio. The objective of this study is to identify the issues associated with visual, thermal and site environmental matter as well as analyze and propose service core that comply with necessary standards and regulations with following considerations: (a) Specification of the appropriate choice of orientation and components with basic understanding of their requirements, characteristics and environmental impact. (b) Analyze the series of configured options. (c) Identify the optimal options. (d) Incorporate the necessary statutory requirements.
The assessment of this project will be based on the following: (a) Understanding of the analysis, space planning, application of services. (b) Quality of drawings, diagrams and images with correct drawing conventions (c) Clarity of specification of all components studied in the exercise, both in illustration and description. (d) Report presentation layout of handbook.

2.0 SITE INTRODUCTION
Figure 2.1 Site Plan (NTS)
Located right in the heart of Kuala Lumpur, Kampung Baru is a top-down initiative from its beginning. This means that the establishment and development of Kampong Baru had been "planned" from the beginning, although the plan was refined over time. The story of Kampong Bharu begins in the early 1900s. His Royal Highness, the Sultan of Selangor, granted the land to the Malays under a special condition that only the Malays could own the land and reside in the area. Kampung Bharu consists of 7 villages and with the land size of 220 acres. The Malay Agricultural Settlement (MAS) was introduced by the British later on so as to educate the children of Malays to take a part in the administration and to enable them to reap some of the advantages of the present prosperity. Since then Kampung Baru has held out against development and modern-city living, turning into a political symbol of Malay culture.

3.3 Wind Direction, Speed & Wind Rose
Figure 3.3.1 Malaysia Standard on Air Speed and Occupant Sensation The Malaysian Standard (MS 1525;2014) provides a guide on the impact of air speed on occupant's sensation. The air speed of 0.5 to 1.0 m/s is generally pleasant when comfortable or warm but causing constant awareness of air movement while the air speed of 1.0 to 1.5 m/s is acceptable in warm conditions but can be from slightly to annoyingly draughty. Thus, the air speed from 0.5 to 1.5 m/s is considered acceptable.

5.2.2 Escape Provision Computation The escape provision in relation to occupancy load is based on the following By-laws: By-law Clause 175 - Calculation of occupant load. Calculation of occupancy loads and capacity of exits shall be in accordance with the provisions of the Seventh Schedule to these By-laws. By-law Clause 176 - Computing storey exit widths.
To compute the required exit width from individual floors of a building(a) calculate the floor area net or gross whichever applicable; (b) determine the allowable occupancy load factor from the table; (c) divide the floor area by the number of square metres per person to determine the number of persons for which exits must be provided for that floor; (d) determine from the table the capacity of the type of exit to be used for the purpose group being designed; and (e) calculate the number of units of exit widths for each type of exit used based upon the capacity. By-law Clause 177 - Computing number of staircases and staircase widths. The following factors shall be used in computing the exit widths: (a) in a multi-storeyed building if x units of exit width are required from each floor the staircase serving those floors do not need to be x times the number of floors served in units of exit width. The staircase need be only wide enough to serve each floor but not less than the minimum width allowed and in every case one of the protected staircases shall be assumed to be inaccessible and the remaining protected staircase shall be of sufficient width and number to accommodate the relevant occupancy; (b) depending on the occupancy, street floor exits have to be sized to handle not only to occupant load of the street floor but also a percentage of the load of the exits discharging to the street floors above and below: (c) Exit should never decrease in width along their length of travel and, if two or more exits coverage into a common exit, the common exit should never be narrower than the sum of the width of the exits converging into it; (d) except as provided in these By-laws, the minimum number of exits is two; (e) at least one of the staircases should be a minimum of two unit width except that 900 millimetres may be allowed where total occupancy of all floors served by staircases is less than 50; and (f) There should be no decrease in width along path of travel of a staircase.
36
By-law Clause 180 - Space standards for calculating occupancy loads. The occupancy load permitted in any place of assembly shall be determined by dividing the net floor area or space assigned to the use by the square metre per occupant as follows: (a) assembly area of concentrated use without fixed seats such as an auditorium, places of worship, dance floor and lodge room – 0.65 square metre per person; (b) assembly area of less concentrated use such as a conference room, drinking room, drinking establishment, exhibit room, gymnasium, or lounge – 1.35 square metre per person; (c) standing room or waiting space – 3 square metres per person; (d) the occupancy load of an area having fixed seats shall be determined by the number or fixed seats installed.

Figure 6.1.1 Massing with Proposed Position of Service Cores
According to the Uniform Building By-Law 1984 Clause 168 – Staircases (1), the proposed college except as provided for in by-law 194 every upper floor shall have means of egress via at least two separate staircases as the topmost floor of which exceed 12 metres in height. The placement of main service core in the proposed college is arranged in the main block of the building which connected other blocks with linked bridges. The main service core is a fire shutter protected lobby with two passenger lifts, all service risers, and a fire-rated escape staircase. Five additional fire escape staircases are provided in the whole building and on each side of the block. One alternative for Block A for the ease of convenience to the connection to the Jalan Dewan Sultan Sulaiman. Two alternatives for Block B which one is alternative for Block A, and another is for the ease of convenience to the connection to the Jalan Datuk Abdul Razak. Two alternatives for Block C to addressing the traffic from Jalan Raja Abdullah which is the main road beside our site.

6.3 Analysis & Options of Core Configuration From the selected core system that is in the main block (Block B) of the building allow best accessibility with linked bridges from both blocks (Block A & C) of building. There are total of 2 building core systems is proposed. Option 1 with separate lift and services and fire staircase by a corridor while option 2 lumps all the services and escape and it has an advantage of structural strength from the reinforced concrete lift shaft.
Figure 6.3.1 Option 1 - Proposed Lift Core Design
Option 1 has a design that separate lift and services and fire staircase by a corridor, and it will be exposed and easily accessible. It filtered and reduced but allowing daylighting into the corridor for user. This organization neatly arranged and easy to be understand by the user of the location of the lift. It also encourages natural ventilation which allows little of wind tunnel effect that making the corridor slightly cooler. 47
Figure 6.3.2 Option 2 - Proposed Lift Core Design
Option 2 has a design that lumps all the services, escape and lift shaft together and the fire escape staircase will be concealed by a row of the lift cores. It allowed excessive daylighting that produce glare effect onto user. This configuration very neat but may confuse occupant with the door for services purpose. It also does not contribute any to the ventilation. After the comparison between option 1 and 2 in term of daylighting, ventilation and space configuration, option 1 is the selected lift core design in the proposed college.
48

Located right in the heart of Kuala Lumpur, Kampung Baru is a top-down initiative from its beginning. This means that the establishment and development of Kampong Baru had been "planned" from the beginning, although the plan was refined over time. The story of Kampong Bharu begins in the early 1900s. His Royal Highness, the Sultan of Selangor, granted the land to the Malays under a special condition that only the Malays could own the land and reside in the area. Kampung Bharu consists of 7 villages and with the land size of 220 acres. The Malay Agricultural Settlement (MAS) was introduced by the British later on so as to educate the children of Malays to take a part in the administration and to enable them to reap some of the advantages of the present prosperity. Since then Kampung Baru has held out against development and modern-city living, turning into a political symbol of Malay culture.

WIND SPEED
The average hourly wind speed in Kuala Lumpur experiences mild seasonal variation over the course of the year. The windier part of the year lasts for 2.9 months, from December 2 to February 26, with average wind speeds of more than 1.8 meters per second. The windiest day of the year is January 21, with an average hourly wind speed of 2.1 meters per second. The calmer time of year lasts for 9.2 months, from February 26 to December 2. The calmest day of the year is April 15, with an average hourly wind speed of 1.5 meters per second.
The Malaysian Standard (MS 1525;2014) provides a guide on the impact of air speed on occupant's sensation. The air speed of 0.5 to 1.0 m/s is generally pleasant when comfortable or warm, but causing constant awareness of air movement while the air speed of 1.0 to 1.5 m/s is acceptable in warm conditions but can be from slightly to annoyingly draughty. Thus, the air speed from 0.5 to 1.5 m/s is considered acceptable.
HUMIDITY AND TEMPERATURE The hot season lasts for 3.3 months, from February 13 to May 23, with an average daily high temperature above 33°C. The hottest day of the year is March 14, with an average high of 33°C and low of 24°C. The cool season lasts for 2.0 months, from November 3 to January 5, with an average daily high temperature below 32°C. The coldest day of the year is January 18, with an average low of 23°C and high of 32°C.
The figure above shows you a compact characterization of the entire year of hourly average temperatures. The horizontal axis is the day of the year, the vertical axis is the hour of the day, and the color is the average temperature for that hour and day. East and South faces of the site exposed to sunlight during the morning of the Winter Solstice. The site does not receives any shadow coverage due to the adjacent massing mostly is low-rise buildings.
There are no shadow received on site due to the position of sun is high above during the afternoon of the Winter Solstice.
The site receives approximately 70% shadow coverage from the residential high-rise building during the evening sun of the Winter Solstice.
The perceived humidity level in Kuala Lumpur, as measured by the percentage of time in which the humidity comfort level is muggy, oppressive, or miserable, does not vary significantly over the course of the year.
RAINFALL
The average percentage of the sky covered by clouds experiences mild seasonal variation over the course of the year. The clearer part of the year in Kuala Lumpur begins around December 26 and lasts for 3.0 months, ending around March 24. On February 20, the clearest day of the year, the sky is clear, mostly clear, or partly cloudy 26% of the time, and overcast or mostly cloudy 74% of the time. The cloudier part of the year begins around March 24 and lasts for 9.0 months, ending around December 26. On May 11, the cloudiest day of the year, the sky is overcast or mostly cloudy 91% of the time, and clear, mostly clear, or partly cloudy 9% of the time.
The table above shows that the rainfall accumulated over a sliding 31-day period centered around each day of the year. Kuala Lumpur experiences extreme seasonal variation in monthly rainfall. The most rain falls during the 31 days centered around November 14, with an average total accumulation of 271 millimeters. The least rain falls around June 25, with an average total accumulation of 112 millimeters.
GIZMO PROPOSAL SIMULATION STUDY INTRODUCTION
The massing utilises the maximum foot print. The picture below illustrate the overall outlook of the design with the massing, showing the 11:00 am sunlight casting at site. For the Daylighting Factor study, it is best to achieve 2%-5%, refering to the table above.
MATERIAL COMPARISON AND ANALYSIS
Angel Gap Length
Standard Concrete
: The angle of the gizmo and planter box can provide more comfortable daylighting and wind to the building. : The gap in between underneath surface of the upper planter box and top surface of the lower planter box. : The length of the shading device will provide sufficient daylight and shade to the interior space.
Polymer Concrete
Glass Fibre Reinforced Concrete
DAYLIGHT : With the optimised gizmo, the daylight factor is able to be kept around 5% for most area of the space, with expection of a small area near the gizmo which is reasonable as a planter box gizmo. WIND : With the optimised gizmo, the wind is able to flow throughout the space including the some area of the multipurpose hall further away from the gizmo. This creates a good passive design wherby the use of electrical ventilation can be reduced.
