This research aims to investigate the impact of agricultural activities on the housing and settlement patterns of the Benue people of central Nigeria. The exploratory sequential research approach was utilized where qualitative and quantitative attributes and consequences were elicited based on the Means-End Chain mode. The study was done in stages between June 2020 and March 2022, with 24 individuals first interviewed and 474 nominal survey questionnaires completed and returned. Preliminary data checks for the subsequent 241 ordinal surveys returned to reveal a significant Bartlett’s Test of Sphericity, a Kaiser-Meyer-Olkin value of 0.872, and a Cronbach’s alpha of 0.934. While the interviews and nominal surveys provide considerable correlations between agricultural activities and the people’s settle...

The relationship was tested in SEM using ordinal survey data obtained between February and March 2022 with 241 valid samples. The mainstream values were statistically validated using CFA while the relationships were generated in the SEM. Results established a significant relationship between values and the people’s preferences for transformative improvements. The findings provide a foundation for long-term policy formation, practical transformative experimentation, and an empirical foundation for future methodological research.

Research paper thumbnail of Validation of Designbuilder Simulation Accuracy Using Field Measured Data of Indoor Air Temperature in a Classroom Building

Heat transfer through the roofs has been identified as one of the causes of overheating in building interiors. Building Performance Simulation tools can be used to determine appropriate roof design parameters with optimum thermal performance in tropical climates like Nigeria. However, ensuring the reliability of the simulation results is essential for both occupants and designers. Therefore, this study seeks to verify and validate the accuracy of simulation results of DesignBuilder as a simulation tool for the present research works on roof thermal performance. The study primarily focuses on the impact of roof design on the air temperature in the indoor learning environment. Validation is examined by comparing the measured daily indoor air temperature of Kofar Wambai Secondary School Classroom, Bauchi city data and the simulation results. Comparative analysis indicate that the % deviation of field measured and simulated results for the tested days (18 th and 21 st September, 2018) were 2.39% and 1.25% respectively. The R 2 results indicated 99% and 75% correlation between the simulated and measured indoor temperature on the tested days.These results agreed with the recommendations of a study by (Andelkovic et al, 2016) which reported that the marginal value of R 2 for measurements and simulations validation is R 2 ≥ 75%. Therefore, DesignBuilder can be employed to evaluate roof thermal performance as well as predict indoor air temperature of classroom buildings.

Research paper thumbnail of USER PERCEPTION IN PUBLIC OPEN SPACE A CASE OF NEW DELHI, INDIA

There are in-numerous cities which are known for their public life while few cities are still struggling to satisfy their users need in public open spaces. Various researchers have defined distinctive factors to assess public open spaces whereas fewer attempted to analyze through users perception. Therefore, this paper attempts to analyze the user perception regarding different attributes of public open space in New Delhi, India in order to validate the present designed space in respect of users need. Three public open spaces from New Delhi, India involved in this study, conducted through survey a using questionnaire. The questionnaire design is based on 'Likert scale' ranging from 1 to 5 which is further analyzed by a basic statistical method. The analysis demonstrates that user's satisfaction level is divergent from present design spaces which leads to ineffective public open space. The result indicates that uses and activities, microclimate, maintenance and security are below the user's expectation level while access and linkages and visual identity are acceptable.
