An Integrated Building Performance Index for Assessing Office Buildings in Nigeria (Published)

Building performance is a function of a number of variables each of which is important to analyse concurrently when conducting a POE study. The development of framework for assessing buildings is significant as it will provide an evaluation tool for ensuring sustainable buildings. This study developed an index for evaluating the overall performance of office buildings in Nigeria. A Total of 51 professionals in the built environment were surveyed. The data obtained were analysed using content analysis technique, pair wise comparison (one sample t-test) and regression analysis. The results showed that; the performance criteria which are pertinent to the performance of office building in order of their importance were building integrity (54.54), indoor air quality (53.69), safety and security (64.04), thermal (46.77), spatial (7.27%), visual (44.01), spatial (43.33) and acoustic performance (43.62); priority placed by individual professional, architects rated safety and security and building integrity (18) most important and acoustic least (9) important, builders rated IAQ and visual performance (20) most important and building integrity (8) least important, estate surveyors ranked safety (21) and building integrity (17) performance most important and acoustic performance (7) least important, mechanical engineers rated safety (22) and building integrity (0) performance most important and acoustic performance (7) least important. A regression model based on the TBP criteria identified was developed (TBP Index = 13.36ð+12.57ŋ+12.46Ɣ+15.34ω+12.38ɸ+15.58φ+18.30ψ). It was concluded that safety and security was rated most significant of all the performance mandates, followed by indoor air quality, building integrity, thermal performance, spatial performance, visual performance and acoustic performance.

Post-Occupancy Evaluation Tools for Effective Maintenance Management of Public Schools (Published)

Post Occupancy Evaluation (POE) involves the systematic assessment of buildings, facilities and surroundings occupied by end-users.This paper examines the POE tools for effective maintenance management of Public School Buildings.  In this study, questionnaires were administered and retrieved from the 331 end-users that is staff and Parents of pupils of the Rivers State Model Primary Schools from 12 selected schools in 6 Local Government Areas out of the 138 completed functional schools. Purposive sampling technique was adopted to select the 12 schools. The descriptive statistical tools such as table, frequency, percentage and relative importance index (RII) were employed in analyzing the data collected. The findings showed that POE tools for effective maintenance management are both quantitative and qualitative methods and the tools include questionnaire, walkthrough observation, photographs, interviews, focus group and survey as the most valuable tools. POE tools are vital effective maintenance management tools employed as feedbacks from end-users for effective integration towards sustainable maintenance. The study therefore recommends POE tools for effective maintenance management of Public Schools in Nigeria
