Energy-efficient Building Envelopes in Oman – A Study

In Oman, extreme hot weather conditions and thermally inefficient building envelopes have led to high cooling loads in residential units. Residential buildings serve a smaller number of occupants per unit, when compared to other sectors in the building industry. Also, mechanical, electrical and other energy-intensive equipment are relatively lesser in quantity and complexity. Yet, as per statistics, the residential sector is the largest consumer of electricity in the industry. In Oman, the residential sector consumes most of the electricity produced, with over 70 % of the load contributed by cooling using air conditioners (Zurigat et al., 2003). A major reason … Continue reading

Trends in Recycling of EPS Foam

Expanded polystyrene (EPS) foam, commonly known as styrofoam, the ubiquitous lightweight material used in packaging of electronic devices, food items and electric appliances, is popularly used because of its water and heat resistant properties. These properties likewise make it a preferred material for disposable food containers such as bowls, plates and coffee cups. Due to its popularity, the global demand for EPS foam and its production is steadily increasing.  According to GBI Research, the global demand for both polystyrene and EPS increased to 14.9 million tons in 2010 from 13 million tons in 2000.1 This is expected to further swell … Continue reading
