C-beam environmental roof

Chalatse, Keketso E January 2003 (has links)
Thesis (MTech (Civil Engineering))--Cape Technikon, Cape Town, 2003 / South Africa is experiencing great movements of people from rural areas to towns mainly because of the need to find work. Accommodation is limited and expensive, forcing many to live in informal homes. The municipalities, in an attempt to accommodate as much as they can, provide small plots, which basically can only accommodate a house and a very small garden. This country like other countries of the world has also embarked on numerous low-cost housing schemes to accommodate the homeless. Because of economic realities and because high-rise options are not considered acceptable, the most practical solution has resulted in large-scale low-density urban and suburban housing developments. Low-pitched metal-sheet roofs are provided because they are the most cost-effective. Lack of space within the homes and tiny surround-gardens are major problems to residents seriously limiting lifestyle. Other problems associated with these developments concern environmentally intrusive effects, the need for better security and other social concerns, and storm water runoff. This thesis discusses a usable flat urban and suburban roofing for existing and new houses by means of a system known as 'C-beam'. A usable greened concrete flat roof replaces the traditional pitched metal-sheet. The new roof provides sitting space for family members and is used to grow plants in pots. A construction manual is to be developed by which the constructors will build the roofing without the use of cranes and other expensive sophisticated construction machinery. The house owner can construct their own flooring/roofing; that is, the process will provide additional jobs, and hence positively affect economy. The manual includes the means of effective control by municipal authorities to ensure adequate and safe standards. Greening of the roofs will not only provide the potential for growing food from the plants, but it will also improve the environment of the area, including the reduction of storm water run-off, by retaining some water in the soil on rooftops.

Design and Implementation of a Pressure-Equalizing Vent System for Low-Slope Roofs

Grant, Elizabeth J. 10 September 2003 (has links)
Winds create forces on buildings, sometimes with disastrous results. Low-slope roofs are subjected to potentially high levels of suction pressure, especially when winds strike the corner of a building, creating vortices. Traditional methods of attaching roof membranes to substrates are prone to failure when the low pressure on the roof surface instigates a transfer of forces to the roof membrane. Existing pressure-equalized roof systems use the power of the wind to transmit low pressure to the space immediately beneath the roof membrane, pulling the membrane down to the roof surface. The object of this study is the design of a wind vent which, when coupled with a single-ply roof membrane in a complete roof assembly, will successfully equalize low pressure throughout the entire field of the roof. The proposed wind vent differs from existing equalizer valves in its use of the Bernoulli effect to create low pressure. Optimized for ease of manufacturing and installation, the vent is omni-directional and contains no moving parts. After the wind vent prototype is developed, future study will be required to determine the tributary area of each vent, the interaction with the insulation beneath the membrane, the response time of the system when subjected to dynamic wind loading, the effect on the vent of various weather conditions, and the permissible amount of infiltration into the roof system. Associated research will also investigate the benefits of incorporating the heat evacuating capacity of the pressure-equalizing roof vent system into a roof membrane containing an amorphous photovoltaic array. / Master of Science
