The study evaluated the physical qualities and satisfaction in students’ housing in selected Students’ Housing for the University of Ibadan. Through survey method, eight hostels were purposively selected to capture variation in gender, level of study and hostel design. The sampling frame showed that 5605 students at UI were found in 2,147 rooms. One out of every 10 (10%) of the rooms were selected which amounted to 215 students selected. The result shows that the functional qualities of the hostels were perceived among the students to be well above average (55.3%). Similarly, both aesthetics (95.8%) and structural (89.3%) qualities of the hostels were perceived to be excellent among the students. Also, respondents were satisfied with various services and amenities provided in the Halls of Residence (54.4%) and 35.3% expressed neutral satisfaction. The study concluded that, Physical qualities and Satisfaction are important in the study of Students’ Housing Design.

This paper exامینes the inter-relationship of three major phenomena- population growth, uncontrolled urban expansion and urban development in Ado Ekiti, Nigeria. Uncontrolled urban expansion has a resultant effect on the urban development of a city whereas uncontrolled urban development is caused by uncontrolled population increase is caused by Migration. This work encapsulates how population growth has affected the urban expansion and resultant land use and urban development in the city. The methodology adopted the use of both primary and secondary data: the population data from the Demography Division of the Governor’s Office and the urban growth Maps (1956 and 2006. Data were analysed and the resulting graphs extrapolated to show the relationship of population growth on urban expansion and urban land use/urban development. Results show a direct correlation between population growth and both urban expansion and land use/urban development: between 1966 and 1976 the population dropped; as reflected in the drop in urban growth in terms spatial expansion of the city and urban development as there was a decrease in urban land use for education, industrial, and other land uses. Between 1996 and 2006, the population increased; also reflected on the increase in urban growth and urban land uses. Result is useful for Physical, Economic and Strategic Planners in formulating policies for urban renewal schemes and Development Control. The result is also applicable to medium-sized and small cities, in the Developing Countries.

Disaster Management and current approaches in this field in one hand only has focused to physical vulnerabilities and in the other hand has included consequential action to reduce vulnerability and improve physical preparation as well as resistance institutional insignificant during the disaster. Therefore, these approaches usually have ignored the capabilities and capacities of residents to reduce vulnerabilities and consequently losses and damage. While recent approaches have entered, the field of disaster management emphasized that at first vulnerability is beyond the physical vulnerabilities and second vulnerabilities have an inverse relationship with the resident’s capacity in the face of disaster. So, community-based disaster risk management need to recognize indicators of vulnerability and community capacity and its relationship is essential. Accordingly, in the first step, the indicators of community capacity and community vulnerability are provided and in the second step based on these indicators, community capacity and vulnerability have been assessed. The assessment of community characters is based on GIS capabilities, spatial analysis tools and SPSS and correlation regression is used for analyzing the relationship of the variables. The results and findings of this research indicate that the vulnerability of urban areas is not only influenced by physical factors, but also social and organizational factors like community organizing and community educating have affected strongly the vulnerability.

The human population has been growing at least at the rate of 1.2% annually since 1960 reaching up to 6.4B in 2002 and more than 7.0B in 2012. In Davao City, the annual population growth rate is running at 3.22% in year 1990, at 2.41% last 2007 and recently in 2013 at 2.36%. The alarming problem we confront today is that the increase in land area for human use does not expand in proportion to population density increase. It is the aim of this study to address the future problems on land and food shortage through the efficient integration of vertical farms on mixed-use multi-storied commercial-residential buildings in Davao City in order to provide income generating condominiums and produce organic crops for residents in an urban setting. The result of the computations showed that the integration of farms to mixed-use residential-commercial buildings in Davao City is highly feasible. The gross profit is highest using gross floor area percentage ratio combination of 50:5:20 for residential, commercial and vertical farm units respectively. (i.e., 50% of the building’s gross floor area should be allotted to residential units, 5% to commercial units, and 20% to farm units). Moreover the gross profit and ROI of the 50:5:20 gross floor area ratio also generated the highest which amounted to Php 1,785,316,198.00B compared to only Php 501,045,100.00M for the typical commercial-residential buildings in five years. This research has mainly focused on the integration of hydroponics, but the inclusion of aquaponic farms in vertical structures can also be further explored.

Buildings play an important role in the energy demand sector. Due to the increase of environmental concerns and renewable energy sources restriction, lighting control systems will play an important role in the reduction of energy consumption of the lighting without impeding comfort goals. Lighting control systems can control lighting consumption according to the type of building, adequate luminance, occupation time, scheduled time etc. Better lighting not only can reduce the energy consumption of a room, it can improve the quality of work from its occupants. The main aim of the project is to determine the energy saved by using different artificial lighting control systems and find the best one. Honeybee plug-in for grasshopper in a space as a classroom simulated six different systems in this article and electricity, cooling and heating energy consumption for these systems were compared. Results show that “Auto dimming with switch off occupancy sensor” has the best annual operation and it saves eight times more electricity energy than the worst system which is the traditional “Always on during active occupancy sensor”. Considering thermal energy consumption also proves the priority of occupancy and daylight dimming system. Selecting a suitable lighting control system in initial steps of design or after construction is very affordable and increases environment quality.

Unsustainable growth of cities and creation a set of contiguous impervious surfaces have result on disorder of natural cycle of water in urban environments. This situation causes flooding and problems due it, pollution of groundwater resources and degrade the quality of the urban landscape by increase the speed, volume and frequency period of runoffs. conventional methods about the stormwater management have failed to demonstrate their effectiveness in this field. Thus, in recent years a new topic are created in the field of urban design that known as "water sensitive urban design". Water Sensitive Urban Design (short: WSUD) is the interdisciplinary cooperation of water management, infrastructer engineering, urban design, and landscape designing. WSUD develops integrative strategies for ecological, economical, social, and cultural sustainability. The purpose of Water Sensitive Urban Design is to combine the demands of sustainable stormwater management with the demands of urban designing, and thus bringing the urban water cycle closer to a natural one. This approach attempts to increase urban sustainability indicators, improve the quality of urban landscape and urban space amenities by offer operational mechanisms in relation to urban design and it attempts not only to close the urban water cycle in its natural cycle and achieve technical goals, but gain optimal utilization of runoff and change the vision of the issue from a threat to a valuable opportunity.The following is a description of some essential methods for sustainable stormwater management. These methods are grouped according to their primary function: water reuse, treatment, detention and infiltration, conveyance, and evapotranspiration. Here is the techniques of water sensitive urban design about stormwater management and link them to urban design concepts, till through that some methods to be introduced that they are more efficient than conventional stormwater management methods about performance, helping to complete the natural cycle of water, environmental sustainability of cities and urban design aspects.

The use of building regulations in architectural design has been a controversial issue for a long time. From the view point of critics, building regulations inhibit innovation, promote conservative design and are incapable of insuring design quality. From the defenders point of view, some professional mentalities of architects regarding building regulations are problematical and must be changed. The present research aims to illuminate the reasons for the above-mentioned tension between architectural design and building regulations. This is done by examining the structural match between architectural design and building regulations. Seeing from a designer point of view, the paper compares formal characteristics of building regulations with architectural design. Three general characteristics of building regulations are found in contrast to characteristics of architectural design. Building regulations are analytical in nature, while architectural design is a synthesis-oriented act. Building regulations are mainly based on a reductionist approach towards defining design problems and solutions, while innovation and originality are considered as fundamental values by most architects. And thirdly, building regulations are usually framed in a way that matches an evaluative mode of thought, while architects often have to work in a generative and predictive mode. These explain why architects from time to time feel frustrated with regulations. The paper continues to make recommendations to both architectural designers and regulators. To the designers some facts and points are stated to help them better understand the nature and performance of building regulations and guide them safely and positively use regulations in their design process. Addressing the legislators, the paper offers some recommendations to facilitate the use of building regulations in architectural design. Moving towards performance-based regulations, a broader involvement of information technology in building regulations, and production of designer-oriented guidance documents are some of these recommendations.
