Study on sustainability and affordability of green building in RWANDA.
The population of Rwanda increase rapidly on the total area of 26338km2. For meeting economic and social development of that larger amount of population, Rwanda has established a policy of pursuing a ‘green economy’ approach to economic transformation. In order to improve the living condition of the population through expansion of country’s infrastructure focusing on the creation of second cities. The green economy approach favors the development of sustainable cities and villages. Green building may be residential house where people would live and make it much easier and more efficient for the government to provide social and economic services to the population in order to improve their living condition for developing the second cities. It is the strategies taken by Rwanda housing authority to target the objective of vision 2020 through economic development and poverty reduction policies Strategy (EDPRS). It is in this regards that the policy of Rwanda through EDPRS II is to pursue a ‘green economy’ approach to economic transformation, where key innovations include: piloting a green city, piloting a model mine, attracting investors in green construction. Spelling out the benefits of improvement of access to social services where people live in houses that are environmental friendly and resources efficient.In terms of environmental impact and energy costs for construction, traditional architecture in Rwanda is 'green', due to lack of financial resources for value added products that are common in industrial country architecture. In terms of energy use, Rwandan homes are intensive users of scarce wood resources for cooking, though other energy requirements, such as electrical appliances or heating, are absent. Institutional and commercial architecture is not environmentally sound, with excessive use of cement and other fired brick materials, lack of onsite wastewater treatment, and little concern for energy consumption. Schools in Rwanda are somewhere in between, with rainwater collection and biogas toilets common, but these buildings often use large quantities of cement and fired brick.This project work is therefore in that line and is about the study on sustainability and affordability of green building in Rwanda, it dealt deals with site selection, the materials used and architectural design of buildings considered as a building model in second cities.
