Residential Building Walls and Environment in Amman, Jordan

Abstract

Jordan has a moderate weather conditions which is overwhelmingly dry. Winter months, December, January and February usually have cold spells with rain, wind and occasional snow. Residential buildings are well built with an outer white stone layer on walls and relatively well sealed windows. Most houses are fitted with central heating systems and water heating using Diesel fuel fired boilers. The high cost of fuel renders limited and intermittent use of the space heating system or as an alternative, the use of flu-less paraffin and gas fired heaters. This in addition to cooking and other occupant activities cause the inside environment to become unhealthy and uncomfortable in winter when ventilation is kept to its minimum. Dampness often leads to mold growth on cold surfaces of walls and ceiling. The present study is experimental with some theoretical analysis of walls thermal properties in an attempt to reach some solutions. The results indicates that insulation of walls plus some means of ventilation with heat recovery can actually save energy, improve inside air quality and avoid moisture.
