IN CONTACT WITH COMMUNITY AND NATURE
A COMMUNITY PRIMARY HEALTHCARE FACILITY
Overview The design is based on the modular concept. A new approach to delivering quality and affordable healthcare to small rural communities. The conceptual design approach was to provide a healthy, stimulating environment based on a ‘’whole-oflife’’ philosophy inspired by the benefits of contact with nature and community. Due to the nature of the environment, the landscape was developed to create a favorable micro-climate and to ensure protection against undesirable wind, noise or fumes and provide privacy. The basic form of building is ideally, based on its functions: • bed- related inpatient • outpatient related • diagnostic and treatment • administrative • service (food, supply etc.) Physical relationships between these functions determine the configuration of the building. Certain relationships between the various functions are required to take into consideration the movement and communication of people, materials, and waste. Thus, the physical configuration of the building and its transportation/logistics systems are inextricably intertwined

Overview
MASTER PLAN
The new buildings seeks to contribute to a lively street life through open and programmed spaces, new architectural expressions and well-defined public spaces. The plan aims to contribute to a unique, diverse and safe environment. The master plan draws on surrounding landscape typologies (forests as well as the urban fabric) to create a permeable and interconnected series of individually programmed outdoor spaces, organized around a central courtyard. A subdued architectural expression privileges the unique landscape as the buildings’ defining design element. The project recognizes gardens as a vital link between culture, nature, and a place to nurture relationships.

ART GALLERY Overview
The task was to designed the interior of an exhibition/art gallery to mimic the works of a renowned architect. This space was designed to mimic that of Japanese architect, Tadao Ando. With his signature use of concrete and the poetic treatment of natural light. This art gallery was designed to be devoted to the exhibition of African art and also a place for thoughtful engagement on cultural and contemporary social issues. Sited in the city of Tamale, it was envisioned to be an integral part of the civic and cultural fabric of Tamale as well as a new kind of exhibition space and cultural resource. “I want to create a space that moves people. It doesn’t matter if it is a house, or a museum, or whatever. So, it is somebody sitting on that lawn, just going around and around and feeling happy. That is something I’m striving for.” – Tadao Ando. “If you give people nothingness, they can ponder what can be achieved from that nothingness.” – Tadao Ando.

DAM
SITE OBSERVATION & ANALYSIS Factors on selection of type of dam crossing • Cost • Durability • Constructability • Maintenance Length of crossing = 184m [150m used in design] Width of Span = 14.8m Design • The preliminary design was undertaken to determine the outline and form of crossing at the identified location. This preliminary design is, however, based on the limited available topographic maps and site investigation of the site. • No detailed topographic survey, as well as cross-section of the dam was conducted during the preliminary survey. • During the detailed design, a more thorough and accurate geotechnical and topographic survey shall be conducted on the site to finalize the structural requirements of both the super and substructure. Based on the preliminary investigation, it's recommended that culverts be placed since dam discharge volumes are quite small where culvert capacities will be sufficient. This will have to be verified again during the detailed design stage. Substructure The choice of foundation system for substructure will depend on the type and depth of supporting soil layer. Ground investigations need to be conducted to determine the appropriate type of foundation.

RENOVATION OF STUDENT DORMITORY [TAMAKLOE HOUSE, TAMASCO] Overview Tamakloe House student dormitory in Tamale Senior High School is currently in a deplorable state. A couple of defects have affected the building's artistic look and compromised the integrity of some parts of the building and the safety of structure.
Point of Reference •
Assess the structure and identify the defects. Suggest preventive measures if possible.
•
Provide an architectural design of a new building.
PRELIMINARY HOSTEL
ASSESSMENT
OF
THE
Visual Observation of the building The two-storey structure has Twelve (12) dormitories [ Six (6) on each floor] with Four (4) cubicles [Two on each of the longitudinal ends of the building].
Ground Floor 1.
There is a non-structural crack (about 2mm in width) at the base of the building [where the apron meets the exterior wall] that runs around the perimeter of the building. This crack is not visible from the inside of the dormitories. There are many other cracks on the surface exterior of the wall.
2.
There is a wide shear crack behind the second dormitory on the ground floor. This has caused the wall to detach from column that supports the structure.
3.
The cubicles at each end of the building have cracks at the lintel level that are visible both inside and outside the building.
4.
The plastering on the exterior wall of some parts of the building have been chipped away exposing the blocks of the building.
First Floor and Roof 1.
The reinforcements of the slab of the first floor at some sections along the veranda are exposed. This has caused rusting of the steel reinforcements in the slab. There are also a few cracks underneath the slab (i.e., when viewed from the ground floor)
2.
The ceiling of the first floor is in an appalling condition. Most parts of the ceiling in all the dormitories are rotting away indicating leakages from the roof.
3.
Most of the structural components (columns and beams) and the staircase are in fairly good conditions.
4.
The window frames and wire mesh (nets) of all the windows are in a bad condition. Almost all the windows in the building have no louver blades.
Causes and Remedy 1.
Ground Floor
There was not enough concrete cover for the steel reinforcements in the slab. To correct this. the concrete material around the cracked area of the slab needs to be removed and the contaminated (rusted) reinforcements replaced or treated if possible.
2.
The roof of the buildings should be checked further for leakages and the entire ceiling of the first floor replaced. The rafters and purlins of the roof should also be assessed to confirm their
First Floor
structural integrity. 3.
Minor cracks on/ around columns should be made wider on the surface with a saw or grinder, and then filled/plastered with mortar.
4.
Wire mesh (nets) and louver blades should be provided for all windows in the building.
Conclusion These renovations and repairs can be done to ensure that the building is structurally safe, beautiful and also extending the life expectancy of the building by another
5-6 years. However additional information from the building drawings and details of construction should be carefully examined before any renovation works begin.

Challenges •
Extensive cracks on various sections of the building due to differential settlement.
•
The building has also been sinking because of the clayey nature of the soil.
•
The poor drainage system in the area causes flooding
•
Noise and dust from the street also causes a lot of discomfort.

The requirement was for a low-cost design intervention. The design brief was to simply extend with two more bedrooms, shops and a fence wall. Vegetation or landscaping elements was added to create a natural ambiance in the house. It was also important to close the house from noise and dust from the road. The façade design was also minimal without taking away from its original identity. The dry and hot climate of the place influenced the whole design approach. Simple, functional, semi enclosed spaces and greenery for a calm enclosed ambiance.

OPTIMIZING A BUILDING’S FAÇADE FOR DIRECT SOLAR RADIATION Overview This is a study of the direct solar radiation on the
façade of a proposed residential building, located in Tamale, Northern Ghana. In a hot climate, characterised by high incident solar radiation, the use of a high heat absorption material such as bricks compared to a reflective material produces significant differences in terms of
surface
and

temperature.
Bricks
simultaneously reduce the heat gains into the building, the energy consumption and the cost for indoor cooling. In Tamale, where the building energy demand for cooling is high, passive cooling strategies presents a suitable solution to improving indoor thermal comfort
and

Challenge The average temperature over much of Tamale averages about 31°C, though it can exceed 40°C at
certain times of the day. This warming reduces thermal comfort, and increases the energy used for cooling or air conditioning. The average daily sunshine typically lasts eight (8) to ten (10) hours.

Design Approach
Design Option 1 - Staggered Perforated Brick Facade
A digital model of the space was made in Rhino and integrated with radiance (radiation simulation tool) through Grasshopper. An annual climate dataset was used to generate the values of sun and sky conditions of the location. The model was then evaluated in terms of the Incident radiation and sun path calculated using a sky matrix in Rhino and the algorithm scripted in Grasshopper. The outcomes of the simulations before and after calibration are presented for understanding the
existing scenario and based on the results, specific design interventions made. The simulations are also used to show the improvements in performance.

Perforations Brick
Climate Responsive Façade Optimization The sustainable aspect on the façade optimization is primarily governed by the use of brick masonry elements as shading devices outside the building envelope especially on the southern facade. Climate simulation of the direct solar radiation on the façade is performed on the massing before and after optimization to get comparative results of the incident radiation and thermal factor.
Façade Detail
Design Option 2 - Hexagon Cells Brick Facade
Climate Responsive Façade Optimization The analysis of the façade is made mainly by the solar path. The placement of brick masonry wall for self-shading of the interior walls and perforations for natural daylight and ventilation are assigned by the
solar parameters corresponding to orientation of the building mass and the usage of the internal spaces.
