“On the Ground Research and Training”Central Africa needs a new generation of experts to help solve regional problems and regional speci ic training. Research on the ground promotes international researchers to establish productive long-term collaborations with African researchers and create an indigenous generation of solvers. Initial CID/C scienti ic and training programs will focus on four overarching issues facing the region:

• Water and Health

• Food Security and Safety

• Climate Change

• Biodiversity

Natural Ventilation - Wind

• Prevailing Winds From West 11% of Year

• Prevailing Winds From Southwest 17% of Year

• Predominant Westerly Winds, between 0.5 and 2.1 m/s (1 to

4.7 mph).

• Ef icient power production usually occurs at 2 m/s

All of the building designs and typologies are oriented to harness

natural ventilation and facilitate cross ventilation. Each building

typology utilizes large pivoting doors across the length of the

south and north facade. When open, the doors act like a series

of gills that capture and draw in breezes which effectively cross

ventilate the space.

To further ventilate the spaces buildings are equipped with a

series of large ceiling fans which draw the hot air toward the high

ceilings so that it can be pulled out with the cross ventilation.

Building Material Strategies

• A heavy thermal mass envelope reduces peak daytime temperatures compared to a light mass envelope.

• Buildings which will primarily be used during daytime hours benift from being siuated on the ground and are able to stay below the outdoor air peak temperature compared to elevated buildings.

• Buildings which will primarily be occupied at night such as the lodging will be constructed of a combination of mass materials and light weight materials, balancing the bene its of both material properties. Furthermore, Building used primarily at night are raised from the ground plane increasing the potential for cross ventilation and adding a sense of security.


Water Collection and Treatment

The Center for Integrated Development Cameroon would be designed to be simple, local, and sustainable. The future campus would invest in a varity of passive and active systems that would minimize the burden of collecting and treating water.

Currently the existing IITA campus gets their fresh water from two on-site bore holes that penetrate deep into the earth giving access to underground aquifers. However, the site experiences a great deal of rainfall that could be utilized to meet the water demands as the campus grows and expands in the future with the addition of the CID/C campus.

The current IITA campus utlizes leach ields and septics to deal with their waste water. CID/C will be looking to more sustainable and productive methods for waste management and will look at implementing systems more which more holistically treat the waste and reclaim the water.

Water Supply


Energy and Water Heating

The future CID/C campus will utilize solar panels for hot water heating and energy demands.

Offsetting the cost of onsite batteries, which would prove dif icult to maintain and would have a limited shelf life due to the climate, solar panels could charge the batteries of a series of electric vehicles which would be used in place of the current leet of diesel powered trucks.

• System allows battery back-up if national electric grid goes down or if it is unreliable.

• An area of 1,740 sf would be required to implement Five-6kW systems• A 6kW System would put out approximately 42,000 kWh/yr• A low energy building uses 5-9 kWh/sf-yr

Cross Ventilation:

The north and south facades are composed of a standardized system of operable doors and windows. The facade opens to a screened in porch and allows for cross ventilation.

Natural Light:

Clearstories facing north bring in cool natural light without additional heat gain and help to vent any hot air that has risen in the space.

Thermal Mass:

Utilizing materials with a large amount of mass for the walls and floor minimize the diurnal peaks helping to keep the indoor temperature more constant and comfortable. These mass elements can be constructed of rammed earth, concrete, or masonry and allow for local construction methods to dictate the appropriate material.

Solar Radiation

Wind

Roof:

The metallic roof has a high albedo which helps to reject and reflect much of the solar radiation

minimizing solar heat gain. The roof is designed to flush rising hot air from the spaces below.

Solar Panels:

The roof is designed for a large solar array that would give the campus a

source of clean energy and help to ride out the periodic brown outs.

DINING AREA

CONFERENCE ROOM

ENTRY COURTSection Through Conference Center and Dining Area

A large lecture room, two meeting rooms, kitchen, restrooms, and dining area are located under one large roof canopy. The roof canopy protects the various programs from rain and direct solar radiation. Furthermore, a series of solar panels is situated at an optimum angle on the roof. The roof is designed to re lect solar radiation while at the same time allow cool northern light to penetrate to the deeper spaces.

The spaces are hyper lexible to allow for maximum recon iguration in support of a large variety of functions and programs. Both the large lecture room and the two meeting rooms feature pivot doors that allow for natural ventilation and lexibility, connecting the open dining area and the meeting rooms.


Ventilated Roof System:

A corrugated metal roof is situated above the insulating roof with a ventilated air gap

inbetween. Through cross ventilation the cavity is flushed and heat gain to the interior from the sun is minimized. The roof is designed to protect and shade all mass elements and openings from any

direct heat gain.

Section Through Learning Center

The construction typology utilized for the Learning Center would be implemented for other buildings and programs including technical training, equipment repair facilities, remote sensing research facilities, research and training labs, molecular and genetic laboratories, and administrative of ices.

The construction techniques utilized for the distance learning center allow the building to function passively by taking advantage of the cross ventilation and limiting any direct and indirect heat gain from solar radiation. Furthermore, the building strategy is designed to ef iciently utilize mechanical cooling when required based on the type of equipment and work being performed.

Collaborative Work Area:

Capping either the west or east facade of each housing aggregate is a collaborative work area for the residents to have impromptu working sessions.

Section Through Lodging

The lodging is lifted from ground plane to increase ventilation during the primary hours of use at night while sleeping. Furthermore, lifting the lodging an additional sense of security. The mass utilized to create the roof and demising walls between individual units provides an excellent acoustic barrier between units, provides a foundation for the overall structure, and helps to stabilize the overall temperature of the spaces.
