Energy Saving in Oman - Part 2

By Akira Katayanagi

It seems that the summer has arrived in Tokyo. Last time I introduced the energy saving project in Oman, but this time I’d like to get away from engineering and look at culture and education in Oman.
Firstly, the state religion in Oman is Islam, so there are mosques throughout the city. When you mention the Arab world the mosque is a popular image, and in Oman many people pray 5 times a day (before sunrise, noon, afternoon, right after sunset and before retiring). For this reason, offices, shopping centres and hotels generally have a prayer room. Even though it tends to make meetings and presentations a little long, they are often stopped for prayers.
Islam is seen as a rather strict religion by most Japanese. Drinking alcohol is not allowed under Islam and women generally cover their figures in a long black dress called the “abaya”. Oman is girded by the Arabian bay, the Straits of Hormuz and the Gulf of Oman with many beautiful beaches but you will not see Arab women relaxing in their swimsuits there. There aren’t so many men on the beaches either do they are very quiet.

However, there are differences in the severity of restrictions depending on area. Oman is considerably more liberal than neighbouring Saudi-Arabia, with many working women and it is accepted that women drive.

Next I’ll talk about language and education. Arabic is the official language of Oman but English is widely spoken. Traffic signs, notices and signboards are basically displayed in Arabic and English so there are no difficulties getting around. Then over half of Omanis can speak English fluently. This is mainly due to the fact that there are a lot of foreign workers in Oman, so it’s necessary as a means of communication. The population is made up of about 2,000,000 Omanis and 700,000 foreign workers.
Another reason why English is fluent is education.

The course of study in Oman is similar to that of Japan, however, the policy at universities is very different. Classes and all teaching materials are in English with none of the textbooks translated into Arabic. It is said that English is hardly studied until an Omani enters a university. I heard that Omanis hardly study English until an entering university but work on it intensively in the first year. Basic subjects and majors are learned from the second, but as these are studied completely in English, it is acquired out of necessity.

On hearing this I suspect that many Japanese, like myself would think “what an effective education system! We should do likewise.” However, if you ask Omanis their opinion, the think that technical subjects should be studied in your mother tongue and that we are lucky to be able to do so. They have to use English to learn technical subjects and this is more difficult than you might imagine. It is only studied superficially as a second language, It is very hard to master subjects in depth and as a result, the level of technical expertise in engineering seems to be underdeveloped. I’m not saying that this opinion is 100% right, but it is thanks to this project that I was led to weigh these ideas.

Energy saving in Oman – Part 1

Energy saving in Oman – Part 1
For 3 weeks from the middle of May I visited Oman to investigate energy saving conditions and power consumption in residential units, as part of a project to draft energy saving measures there. It exactly coincided with the holding in Japan of the world cup qualifying match between Oman and Japan.

I covered this project in and earlier blog, but with the aim of promoting the saving energy policy to control electric power consumption in Oman which an electric power demand is rapidly on the increase, this project team is composed of specialists in various fields in order to formulate the most appropriate energy saving policy for Oman through a succession of meetings with the government of Oman.

I really got to experience the climate and temperature in Oman. From the standpoint of energy usage the year in Oman can be divided into 2 main periods, the summer season from April to September, and the rest of the year when basically little or no power is necessary for either cooling or heating. In particular the heat peaks between June and August, when the average temperature reaches 40ºC. It was my first experience of such heat, and just walking in the mid-day left me dizzy. Then on the roof top where the A/C outside units were installed it exceeded 50ºC, and sweated profusely while working there. However, the mid-day humidity was low at about 20%, so it was not so bad in the shade. With this kind of heat, I suppose that the cooling of offices and shopping centres to below 22ºC is looked on as a kind of complimentary service.

What was of deeper interest on this trip were the power measurements actually taken in households, and what temperature settings or specifically the temperatures at which people live, in order to understand current power usage. Over 50% of power generated in Oman is used by households so the first thing to do is to promote residential energy saving. Next time I’ll introduce the actual measurements we took.
