INTEGRATION OF CLIMATE RESPONSIVE BUILDING ELEMENTS IN THE DESIGN OF FACULTY OF ENVIRONMENTAL STUDIES, FEDERAL UNIVERSITY BIRNIN KEBBI

ABSTRACT Traditionally, buildings were designed based on the pre conditions given by the surrounding environment, along with available natural resources to create comfortable and safe places. But nowadays, with the advent of mechanical method of heating and cooling, buildings have become less connected to their specific environment and more dependent on technical systems to comfort spaces, thereby consuming large amount of energy and harming the ecosystems of the environment through ...

ANALYSIS OF URBAN GROWTH AND INFRASTRUCTURAL CONDITION IN PERI-URBAN NEIGHBOURHOODS IN MINNA, NIGER STATE

ABSTRACT The rapid expansion of cities in the 21st century is a cause for concern. More worrisome is the uncontrolled expansion of urban areas in the cities of developing countries and the associated housing and infrastructure deficit. Third world urbanization is associated with unplanned development at the periphery of cities, thus engendering unapproved land use and land cover changes. The aim of the study is to assess urban sprawl and ...
