Effect of Perceived Muda on Perceived Job Productivity in Public Office Buildings in Nigeria

A Survey of Environmental Performance Enhancement Strategies and Building Data Capturing Techniques in the Nigerian Context

“…Quantifying the subjective thoughts of the survey respondents ensured that most questions after the demographics were based in the form of a Likert scale of "very significant/very often" to "least significant/never", with the options for evaluation allotted from a score of 5 (very significant) to 1 (least significant). Mean values greater than or equal to 3 (≥3) indicated that the respondents' perception of the variable is significant, while those less than 3 (<3) suggest that the perception is less significant [11,30]. The mean was used to determine the levels of variation in the professionals' perception of building performance improvement and reasons for the selection of certain data-capturing technologies.…”

“…Studies by De Wilde [19] and De Wilde [20] also reiterate that an office environment should provide the necessary user comfort that promotes well-being, health, and productivity. New expectations and current challenges require the need to improve the environmental performance of existing office buildings given that around 87% of existing buildings will be standing by the year 2050 [11]. Thus, regular performance evaluation gives an insight into the percentage of effectiveness and efficiency of a building in meeting users' needs and expectations.…”

“…Thus, impeding opportunities to improve the existing building stock. Periodic feedback about a building's performance is vital for continuous and consistent improvement [11]. While the plan for generators is becoming a fast-growing part of the architecture within the built environment to meet the desired comfort and productivity in offices there is also the argument that offices are built with little or no climatic adaptation [6].…”

“…Although population growth requires new building development, a significant proportion of the existing buildings remain in use [11]. Other than for historical reasons where a significant number of existing buildings cannot undergo demolition and reconstruction, improving the environmental performance of the existing building stock could be more cost-effective than reconstruction [11,12]. Traditionally, understanding the condition of buildings was conducted informally.…”
