Project Overview The project is an extension of the King Faisal Conference Center in the northern region behind the theater which is located on the axis that connects the main entrance of the university with the Higher management of the university.The project focuses on designing a reception hall to welcome the Custodian of the Two Holy Mosques and dignitaries. The project will include a reception hall, a multipurpose showroom and a royal waiting room. Schematic Design The main distribution of the main spaces of the project consists of three main spaces: the internal exhibition area and the service area, such as elevators, etc. and the outer envelope area. It has been distributed to ensure the efficiency of the space and to ensure access to the largest indoor space is open for display as follows: The outer cover contains the afforestation area, the plants as well as the structural load area, the medium cover contents services, the toilets, the vertical movement, and the inner space as the main open exhibtion area without internal columns.

1.3.4. Sectional perspective

In warm-humid zones it is recommended to consider separated and scattered buildings with free spaces between them to utilize air ﬂow. In the proposed design for FED, buildings are grouped close together to give some shade to each other and to provide shady narrow streets and small cool spaces between them. Having believed that buildings must touch earth gently, one challenge one has to deal with when designing the masses of the building is the creation of a massive structure that provides adequate shade while it is completely penetrated and has light impact on the environment.

Atriums have many advantages as a building form over conventional modern building configurations. Atrium buildings appeal to people not only logically, but also emotionally by providing a connection to the outside inside. By bringing natural light into the interior, atriums offer larger, more efficient floor areas than conventional buildings. Atriums provide more desirable work environments by providing more space with a connection to natural daylight and the outside environment. Many believe that access to natural full spectrum lighting creates a more healthful and productive environment. There have been several studies that support this view. The complexity of atrium design does not lend itself to prescriptive standards, but sound life safety principles must be incorporated into every atrium design. Good atrium design will maximize the natural environment to minimize energy consumption (wbdg.org).

1.3.2. The three basic masses surrounding the central atrium and entrance lounge

While providing daylight via the atrium is importans, it is strictly important not to end up with a large surface are of glass that is exposed to direct horizontal solar radiation. The use of wafﬂe slab to control the openings would be a good approach to be investigated.

For the FED building a three sided atrium is considered. It abuts three sides of the occupied portion of the structure and connects the building with the urban surroundings. Natural light as it pertains to atriums is a basic element of the design. The light within the atrium as well as the light transmitted to the adjoining occupied space forms an essential part of the design.

Modular design of educational spaces offers great deal of flexibility and cost effectiveness. A correlation between the minimum required area for a university classroom and a design studio should be investigated. Assuming a design studio will be run by two tutors, each is responsible for 12 students (recommended!), a studio room should occupy a minimum of 24 students. After identifying the dimensions of the basic modular unit that ergonomically fits a certain number of students in their design studio atmosphere, several units can be multiplied to form one basic studio unit. A single module small module fits six students. Concentrating building services and ductwork in the ceiling area over the corridor is a method to achieve high ceilings in the office, classrooms and studio areas.

A waffle slab gives a substance significantly more structural stability without using a lot of additional material. This makes is relatively thinner than conventional slabs. It is possible to create openings through the slabs for skylights for instance. Lighting fixtures can be incorporated in the pocket of the slab.

An effective way of preventing uncomfortable conditions in the extreme case of morning summer east sun in Jeddah is to intercept the sun’s rays before contact with the glass. Shading can dramatically reduce the solar heat gain and glare, signiﬁcantly reducing air conditioning and comfort control costs.

COMMUNICATION WITH EXISTING STRUCTURES (CAMOUFLAGE) The innovation platform casts its shadow in the form of an abstraction of its color palette onto the pavement and facades of surrounding structures resulting into a well deﬁned series of art galleries.

INNOVATION PLATFORM

THE SITE BENCH

RETAINING WALL

THE AMPHITHEATER

To integrate the project elements, the innovation platform projects itself upon the surroundings. Hence, creating a different experience along alley, the buildings and the entire open spaces.

Utilizing the retaining wall as an extended seating bench, emphasizes the longitudinal nature of the campus ground and the separation between the urban and the organic contexts.

To overcome the level difference situation of the site, a retaining wall is introduced. This element separates the upper galleries from the rest of the campus outdoors.

Throughout history, amphitheaters have always been the symbol of mankind inquisition and debate. The adoption of the amphitheater’s spirit became the driving building block for the entire landscape of the campus.

BASIC CONCEPT

THE ART WALK

LANDSCAPE CHARACTER

The notion of creating an institution that fosters creativity and innovation led the designers to constantly refrain from indulging in complex forms with the belief that what this college needs is a plain, yet stimulating, environment to achieve its ultimate objective.

An extended urban ally ﬁlled with artistic experiences along the entire site.

The landscape character adopts the basic circular form highlighting the amphitheater notion and the minimalist treatment of the entire planting areas.

This is the philosophy that underlies this proposal which we believe will allow the public to fully appreciate the product of this institution that will be reﬂected in every corner of the site through a festive display of students' work.

This 4 dimensional space will develop over time (the fourth dimension) as a result of the continuous educational evolution taking place in the JIC.

Using Simulation (IDA ICE) IDA Indoor Climate and Energy. is a Building performance simulation (BPS) software. Multi-zonal and dynamic study of indoor climate phenomena as well as energy use. The implemented models are state of the art, many studies show that simulation results and measured data compare well. Three spaces are allocated (classroom space allocated space from the corridors for each classroom and allocated space from the atrium for each classroom). The classroom space was filled with the same number of users of this space under the real circumstances then opened all the three spaces to each other. The results are shown as shown in the diagram below. (Figure 6)

1.2 Problem statement Spaces greatly impact the lives of occupants. Indoor air quality (IAQ) is an essential factor that decides occupants’ level of satisfaction and performance. Classroom critical due to high density, the over-crowdedness of classroom is a serious and quite common issue, where education institution commonly is overlooked or ignored as the retrofitting of these spaces has limited or no budget for quick solutions. The larger the classroom, the greater the dilution of levels of carbon dioxide (CO2) and pollutants, and the longer good air quality can be maintained. In an average size classroom with a volume of 181 cubic meters, 30 students and no ventilation, the air quality becomes poor in just 30 minutes [1]. Investigations are needed to provide more information about the indoor air quality in Saudi Arabia classrooms and its effect on the space efficiency and educational system.

(L. Schibuola, et al, 2016) recommended installing CO2 sensors as a parameter of the IAQ condition in the classroom. Also, promoted conscious ventilation in each classroom by involving the teachers to manage the manual airing and suggests frequent and short periods of window openings [9]. Measurements devices were installed in one of the buildings of the current preparatory year in educational classroom to measure the quality determinants of these enclosed spaces as shown in the drawings. The designed occupation capacity of the classroom is 40 students. The variables were monitored in more than one period depending on the space condition in terms of use. Install accurate measuring devices that detect and record environmental quality variables at indoor spaces where they measure temperature and relative humidity within the case sample. (Figure 1)

We notice a decrease in the highest value of the CO2 concentration in educational spaces from 2008 PPM to 880.8 ppm, and this is a very good improvement. Looking at the average values of CO2 concentration levels in educational spaces, we find that it’s generally decreased by 49.3%, as we can notice a slight increase in CO2 concentration levels at the corridor’s spaces (the highest reach 1088 ppm) which is acceptable.

Since there are low occupants densities spaces in some of the internal spaces such as the corridors and atriums, the problem can be avoided by using the air switch between the spaces are usually occupied only for short times (breaktimes period) and spaces with high intensity of use (as the classrooms). (Figure 7) Applying the proposed solution idea by using the simulation programs. Using all the spaces on one of the building floors will be opened to each other to verify the effectiveness of the proposed solution (Figure, 7).

Abstract: This paper studies the classrooms indoor air quality of the preparatory (freshmen) year at Jeddah. An existing and active building was used as a case study. The variables affecting the indoor air quality were measured and analyzed by installing sensors to measure and record these variables in this classroom. After that research was done to determine the optimal range of these variables and compare them to check whether these results were within the optimal range of each variable or not. The results show that it is important to propose improvement measures to reduce CO2 concentrations and ensure thermal comfort. Users need to realize that the quality of the indoor environment is important for their health, comfort and efficiency.

CO2 concentration can be reduced by reducing the number of students in the classroom, the large number of occupants in the indoor spaces increases the rates of CO2 concentration. Standard: Classroom square or rectangular 65m2 with furniture in rows and freely arranged fits for 30 - 36 students (which means 1.8 - 2.0 m2 for each student) [11]. According to the standard, the student number was reduced to 30 students in the classroom, we can notice a slight decrease in the CO2 concentration level by 12.5%. (Figure 5)

01 INTRODUCTION 1.1 Abstract

03 ANALYSIS 3.1 Maintaining thermal comfort study

Setting standards to develop educational spaces has become necessary due to the importance of education and the high number of students in the classrooms in the current era. Among the problems that result from the high numbers of students in the classrooms are high levels of carbon dioxide, which may result in health damage and a decrease in educational performance among students and This study was based on a study of a classroom at King Abdulaziz University by measuring devices to determine the levels of carbon dioxide during a full school day and the measuring devices showed the rise of carbon dioxide above the permissible standard according to the American Organization ASHRAE, and to find design criteria to develop the quality of space, an electronic model was built through simulation programs and the development of existing architectural spaces and also rescheduled periods of opening the current architectural spaces to compare them with other solutions to reach better standards that can be relied upon in fact to develop the current design standards for the classroom.

This chart was a result of one work day from 5AM to 5PM , The chart shows the CO2 level exceeded 1000 PPM from 10AM to 2PM which was the time that the students where present . (Figure 2) The air temperature was between 22C and 23C and it didn’t change much because the room cooling depends on air central unit and the room doesn’t use natural ventilation system. (Figure 3)

1.2 Problem statement

3.1

many studies have shown that the rise of carbon dioxide in the classroom leads to health problems and affect the educational levels of the student . [3] Most of the global standards set 1000 ppm as the maximum allowable level of carbon dioxide within the spaces, The European standard determines the level of renewable air per person per hour according to the level of carbon dioxide one of the most affordable methods is natural ventilation, but it requires that the local climate be appropriate. Therefore, in hot areas, mechanical ventilation can be used as an alternative, but to reduce energy consumption and reach better results, we can use the hybrid system as a solution.[4] Achieving in optimized hybrid ventilation system that helps provide on Increases indoor air quality with low thermal complicity and energy consumption this study aims to test the current windows on the classroom and also propose a different windows that can increase natural ventilation inside the classroom without affecting energy consumption or thermal comfort.

3.2 Scenario planning

02 METHODS 2.1 Methodology The research sample was Classroom located in the second floor of king abdulaziz university floor area of the classroom are 7.5 * 9.14 m total number of occupants 40 The classroom depends on a central air conditioning system and on three fixed windows. After selecting the research sample, the measurements on the date 7/10/2019conducting the measurements on a working day. the classroom has non-operable windows and reliance was on mechanical ventilation only. and the door was closed during the lectures and the door opens between the lectures only. by using hobo mx CO2 logger measuring device the device took a reading every 10 minutes (Figure 1).

Scenario 1.

By opening the current windows in the classroom and rescheduling them according to the times of the high rate of carbon dioxide gas above 1000 ppm and comparing the results with each other through heat levels and energy consumption. The window was opened at 25% by simulation model in ida ice. Even with the window opining at 25% ratio the carbon dioxide level was still above 1000 PPM (Figure 4) . When the window was opined the air flow level reached above 200 L/S . The temperature raised near 33C due to the air change between the inside and the outside. The energy consumption was increased to near 200 to sestina the air temperature . The window was opened at 50% by simulation model in ida ice When the window was opined at 50% at 9PM it decreed below 1000PPM (Figure 5) . The window was opened at 75% by simulation model in ida ice. When the window was opined at 75% at 9PM it decreed below 1000PPM (Figure 6). The window was opened at 100% by simulation model

The temperatures were compared with the levels of carbon dioxide in each case so that we can conclude the best case in terms of high levels of heat with each different opening for the window and compare it with the level of carbon dioxide (Figure 14). Energy consumption levels were compared with the levels of carbon dioxide in each case so that we can infer the best case in terms of high energy consumption levels with each different window opening and compare them with the level of carbon dioxide (Figure 15). Air movement levels were compared with the levels of carbon dioxide in each case so that we can conclude the best case in terms of high levels of air movement with each different opening for the window and compare it with the level of carbon

4.2 Discussion This research focused on finding a solution to find ways to improve the quality of indoor air for educational classes through hybrid ventilation systems. As the research has shown us, hybrid methods for ventilation are a suitable solution and can be applied through existing windows or by developing better windows. These same methods can be used on other areas with a different climate Different from the one in which the study was held, as the research showed that increasing the number of students within the educational space may affect the quality of the educational space, which causes a decrease in the level of educational achievement and an increase in the level of health risk for students

STUDY FRAMEWORK

INTRODUCTION This study focuses on the quality of natural lighting within educational spaces. Because they are disproportionate to the space function, the lighting is either low or much higher than the space requirement. After studying and evaluating the current situation, we will study one of the most important factors affecting improving the quality of natural lighting is the shading and reflection systems. Then, several proposals were made to design different windows and shading systems and simulate their impact on the quality of the intensity of natural lighting in the classroom and their impact on different facades of various types through simulation programs for natural lighting (Revit daylight analysis - DiaLux). Based on the simulation results, different proposals and their different effects were compared for each interface.

Thermal bridges emerge as a result of design and construction errors. Heat loss through thermal bridges causes the building’s energy requirements to increase, and .this is related to a great increase of heating expenses Already during the design phase, it is worth considering proper protection of spots sensitive to the emergence of thermal bridges, i. e. balconies, ledges, parapet walls, .terraces, etc

2.12. Vertical extension of the Faculty of Architecture and Planning Design studio excercise with focus on integrated planning taking into consideration the need to cooridnate the architectural design with structural and construction challenges Credits: Nawaf Albishi | Supervisor: Mohannad Bayoumi

Overview The design idea creates a new independent structure on top of the existing building structure of the Faculty of Architecture and Planning. This step was made to enhance the quality of life in the architecture design studios and faculty office spaces. The proposal also considers new usages for the old structure that include administrative facilities and workshop rooms. The massive existing cores of the building have been rebuilt and used to support a vierendeel beam that holds three floors of academic facilities. The space between the existing roof and the new buiding will be reserved for public activities.

Overview The project aims at creating spaces for companies that represent the industry sector to be located in a close proximity to the academic institution. The proposed learn and working environment shall help students and scientists transform their ideas and patented solutions into commercial products. The design suggessts a series of spaces that share a common roof outdoor space. A large canopy os also integrated as part of the rooftop remodelling of the building. Several chimneys have been incorporated into the atrium to enable stack ventilation of the existing spaces in the lower floors. CFD modeling of the performance of the chimney has been considered and can be reviewed in the detailed presentation.

Abstract:

In Zeiten akuten Klimawandels sind energieeffiziente Hochhäuser v. a. in wirtschaftlich wachsenden Regionen dringend notwendig. Das Hochhaus als Maßnahme zur Verdichtung bietet zahlreiche Potenziale zur Nachhaltigkeit, die u. a. die Nutzung der vor Ort verfügbaren erneuerbaren Energien einschließen. Man geht davon aus, dass nach dem heutigen Stand der Technik Hochhäuser in der Zukunft nicht nur Energie sparen, sondern dem Verbrauchernetz sogar Energie spenden können. Sie werden deshalb einen Teil der virtuellen Kraftwerkslandschaft darstellen. Mit Hilfe der im Rahmen dieser wissenschaftlichen Arbeit entwickelten Optimierungsalgorithmen können Architekten in der frühen Planungsphase Entscheidungen über die Maximierung der energetischen Performance des Hochhauses treffen. Der Schwerpunkt liegt dabei auf der optimalen Integration von Solar- und Wind-energieerzeugung sowie der Energieeinsparung.

The need for energy efficient high-rise buildings is becoming imperative, especially in rapidly growing economies. This building type, a key for the densification of cities, offers potentials for sustainability that include the exploitation of on-site renewable energy. It is suggested that the high-rise building of the future should not only consume less energy, but rather provide energy to the grid. Building integrated energy generating devices are becoming essential components of many low- and high-rise buildings today. However, achieving net-zero or plus-energy balance in high-rise buildings postulates meticulous adjustments on many levels to achieve a successful synergy and to overcome technical insufficiencies. This research focuses on optimising the incorporation of building integrated photovoltaic and vertical-axis wind turbines in building façade and the building body, respectively. The algorithms developed within the scope of this dissertation enable architects to make early decisions on the energy performance of high-rise buildings with regard to energy savings and energy generation strategies. The embedded simulation and evaluation programmes in the optimisation process consider the impact of the optimised criteria on user comfort and formal quality.

Abstrakt:

OBJECTIVE To come up with a series of planning assisting criteria for optimising high-rise facades in the selected location, considering energy conservation and energy generation. This scientific work questions the possibility of covering the annual lighting and cooling demand of high-rise building through its facade. It also questions the optimum cooling energy generating system, whether by compression via electricity or by absorption via heat energy (solar cooling).

EXCESS

Besides optimising the facade, it is important to examine the possibility of adding extra vertical or horizontal surfaces for further energy generation. This means extra facade areas that don't cover used spaces that require energy. The extra areas, contribute positively to the energy generated balance. The question remains, how high or how long the extra areas should extend and which tilt angle will they have.
