Abstract

The study is focused on determining the relationship between surface temperature of building envelope and ambient indoor temperature for non-plastered Adobe Brick building. In this study, data was obtained by measurement of wall surface temperatures internally, externally and the corresponding ambient temperature of spaces enclosed by these walls at given time intervals. A corresponding but non-linear relationship between the three (3) temperature readings was established with the wall surface temperature being cooler across the temperature spectrum recorded. This temperature lag between wall and ambient temperature increases as the day proceeds and reduces at close of day. The ambient indoor temperature level rise from 30.5 o C min to 38.2 o C max between 8:30am – 2:30pm. This is higher than what has been established by previous research for optimal human performance in living spaces. The research recommends insulated interior walls to control heat gain into the ambient space via walls. Externally, soft landscape elements and change of building orientation can be used to regulate the micro climate. The use of mechanical means of temperature control, albeit non-sustainable, might be used as last resort to make these interior spaces more habitable.

Highlights

Indoor air quality (IAQ) is a major concern to businesses, schools, building managers, tenants, and workers
This research posited that an adobe mud bricks plastered on both surfaces had indoor temperatures below ambient temperature at critical hours compared to Plastered Cement/Sand Sandcrete Blocks
3.1.1 Temperature Measurements In order to consider, the impacts horizontal and vertical variations in temperature within the room, ambient indoor temperature readings were taken at three different locations in each space and at two different levels corresponding to the body level and the ankle level in the offices corresponding to approximately 0.1m and 1.2m above floor www.iiste.org levels respectively

Summary

Introduction

Indoor air quality (IAQ) is a major concern to businesses, schools, building managers, tenants, and workers. This is due to the fact that it has significant impact on the health, comfort, well-being, and productivity of the building users. Other research indicates a Neutral Temperature as 29.4oC for a naturally ventilated office building in Jos Nigeria This Neutral Temperature of 29.4oC falls within the range of the adaptive Psychometric Chart of between 220C to 310C (Jimoh, 2017). This research posited that an adobe mud bricks plastered on both surfaces had indoor temperatures below ambient temperature at critical hours compared to Plastered Cement/Sand Sandcrete Blocks. Plastered Cement/Sand Sandcrete Blocks is the predominant enveloping materials for office buildings in this research. 01 Clay Bricks With Paper Straw Or Wool >0.35 W/m2K Goodhew and Griffiths, 2005
