CASE 01: NAIROBI CITY MARKET
1.0: BACKGROUND INFORMATION:
1.3: HISTORICAL BACKGROUND AND INCEPTION According to Business Daily Africa, July 2016, the idea of a municipal market in Nairobi was discussed as early as April 16th 1900 when the Nairobi Municipal Regula ons were published. Nairobi City Market was planned to accommodate only Europeans. Jeevanjee decided to build a market for all in 1904 at a cost of 100,000 rupees along Monrovia Street (formerly Gulzar Street). Jeevanjee market was located between Muindi Mbingu Street (formerly Steward Street) and Koinange Street (formerly Sadler Street). By the 1920S, Nairobi was rapidly developing and the need for a new, modern design municipal market rose. Juvanjee Market was pulled down and replaced by a new market along Muindu Mbingu Street, now known as Nairobi City Market.

1.4: FORM AND BUILDING MATERIALS
The site of the project is in an urban se ng, this means that land had to be u lised fully while keeping in mind vehicular roads that lead around the building. This also meant that the market had to be as flexible as possible to serve many purposes that may arise within a region of many occupants.
City Market and the parking lot at Market Plaza were gaze ed as a na onal monument in April 2009, meaning no development can take place without the direct authority of the Na onal Museums of Kenya.
The main hall has a pyramidal form made possible by the use of reinforced concrete arches. The upper eleva ons feature large glazed steel casements windows, some of which are pivoted and operated by a series of steel cables and pulleys for natural ligh ng and ven la on.
The main building houses several shops including grocery shops, florists, butcheries, and curio shops, most of which date back to 1940s. The market has four sec ons. The first sec on is the curio sector displaying Kenyan culture and artefacts. The second sec on is the butcher sector, selling fresh meat and fish. The third sec on is the food stalls sec on selling roast meant, while the fourth sec on is the flowers sector selling fresh flowers for all occassions. The ground floor of the market has fish and meat stands with rented fridges flanking the main building. Also located on the ground floor are fruits and vegetable vendors.

Nairobi City Market has an ornate roof shaped like a hangar, making it look more like an airport structure in comparison to Nairobi's skyscrapers.
Nairobi City Market is located along Muindi Mbingu Street in Nairobi Central Business District (CBD). The market is on the junc on of Muindi Mbingu Street and Market Road, near Koinange Street. The Kenya-Uganda railway line ran along Loita Street, making City Market a convenient selling point. In 1940s, the railway line was relocated making it cumbersome to transport bulky fresh produce to the market.

Nairobi lies within the part of Eastern Africa influenced by the large scale pressure systems of the Western Indian Ocean and the adjoining con nents. The region experiences high temperatures due to proximity to the equator however, its al tude of about 1700 metres results in temperatures which are neither uncomfortably low at night nor high during the day, with an annual average temperature of 170C.
The market has classic features of Art Deco architecture: 1. Symmetrically stepped walls 2. Straight lines at every turn.
As Nairobi is situated close to the equator, the differences between the seasons are minimal. The seasons are referred to as the wet season and dry season. The ming of sunrise and sunset varies li le throughout the year for the same reason Under the Köppen climate classifica on, Nairobi has a subtropical highland climate. It experiences cool evenings in the June/July season, when the temperature can drop to 9 °C The sunniest and warmest part of the year is from December to March, when temperatures average in the mid-twen es Celsius during the day.

According to an ar cle in Business Daily in July 2016, City Market was designed ahead of its me, par cularly situated tot he intented func on of a public market in the equatorical climate where electricity supply is unreliable. The external walls feature a series of concrete sun shading fins. The site layout of City Market minimizes heat gain through solar radia on by having all windows on the nothern and southern facades. The market has a series of courtyards around the main hall which allow cool air to enter the facility, providing sheltered outdoor spaces. The main hall has a pyramidal form made possible by the use of reinforced concrete arches. This form results in high solar radia on within the building, but this has been countered by the use of deep sun shading concrete fins externally. The market has a rela vely low height, exposing a small surface area for heat gains. The cream-white finish of the walls helps reflect away solar radita on. The extensive use of concrete throughout the structure provides a high me-lag, keeping the interior rela vely cool. The spepped roofing of City Market provides external light shelves which reflect light into the interior space, breaking it into even, diffused ligh ng. NATURAL VENTILATION The main facade has ven la on gra ngs on the windward side that direct windfow into the building. These openings are located on either side of the market and ensure closs ven la ons. The main facade also has pivoted window openings allowing air movement into the building. High louvered windows on the nothern and southern facades allow for stack ven la on. Warm air rises and exists through the louvers, allowing cool air to come into the market through the lower openings.
