Climate change affecting the world, and the Sultanate of Oman is not immune to it, requires movement to find solutions to limit its effects, and the infrastructure represented in commercial and residential buildings is one of the most important sectors to these effects have been exposed, and the damage caused by climatic conditions to buildings and the noticeable rise in temperatures require you to keep abreast of technical advances in construction and architecture to reduce any potential impact in this direction.
Omani architects called for the need to establish a national building code, and to speed up the adoption of laws allowing the use of modern technologies in construction, and came up with solutions and economic proposals for the problem of hot climates. and offered the cooling of buildings and houses. in the Sultanate of Oman.
Engineer Badr bin Nasser Al Hadabi, CEO of the Fulcrum Stone Office for Engineering Consultations, believes that according to the building specifications in the Sultanate of Oman, there is no clear protection and designs for climatic conditions, prompting the need to change the Omani building code to withstand climatic conditions, infrastructure development, water drainage and urban planning. and urban areas so that what can be moved from neighborhoods and houses from low areas to safer and higher areas. ”
As for new buildings and how to make them environmentally friendly, Al-Hadabi has indicated that there is no specific legislation and laws for it yet, but the eco-friendly house benefits from the energies present in the universe, such as solar energy, air and wind energy, reducing electrical consumption in buildings and other features, and it Through various things, including choosing the right materials such as heat-insulating bricks, using lamps that consume the least energy (least voltage) and for low consumption, and also the choice of air conditioners of the appropriate capacity for this, which reduces large halls and windows overlooking the sun, and determines the general location of the building to benefit from the sun and not the heat.
Regarding the environmentally friendly techniques in construction, Al-Hadabi says: “There are many technologies in this field, including water recycling techniques, so that the water has to be divided or drained into gray water and used in the irrigation process and even laundry. processes, etc., and which is called the use of the so-called With a Smart Home or (smart home), which reduces heat so that lights and air conditioners are turned off when there is no person at home, and also provides a clear measure of the amount of energy used in the house or building at the same time. ”
Speaking on the appropriate and economic solutions to the problem of the hot climate and the issue of cooling buildings and houses in the Sultanate of Oman, al-Hadabi said: “There are many solutions to this problem, but first there must be legislation. for the use of insulation materials, including treated clay (used in many developed countries, including the United States), which significantly reduces heat and its origin is like the sarooj used in the Omani castles, but unfortunately there is no legislation for it not, because in the Sultanate of Oman we use British systems or British code in construction, and when the relevant legislation is available, the law is found and can therefore The use of these materials in construction, because the amount of energy emanating from the going home is because of the air conditioning and because the bricks do not insulate heat. ”
Al-Hadabi called for the speedy adoption of laws allowing the use of these technologies in Omani construction or the Omani Code because of their great economic benefits and benefits for interior comfort in homes and buildings, which provide all amenities while saving energy. .
Engineer Muhammad bin Hashil Al Riyami, in turn, indicated that the building designs in Oman and in light of the rules governing the designs are to some extent good, but the issue is not related to the building but to the urban plan, and here lies the problem, and as happened in Hurricane Shaheen, the floods swept away the houses built in areas’ valleys or in the areas of water drainage, and most of the losses were in these areas.
With regard to environmentally friendly buildings, Al-Riyami indicated that there are no studies in Oman that are concerned with the reality of evaluating new existing buildings, whether they are environmentally friendly or economical, and in general there is no legislation on the moment not and there is no national building code.
Al-Riyami explained that there are many environmentally friendly technologies around the world, one of which is 3D printing, as construction takes place in a few days and the waste in building materials is very small, and there are other technologies, namely the lightweight steel structures ( LGS) technology, and there are buildings in Oman that have used this technology. .
He added that there are economically appropriate solutions to the problem of the hot climate experienced by the Sultanate of Oman and the Gulf in general in the summer and the issue of cooling buildings within the World Climate Summit system in which the Sultanate of Oman participated, such as as well as the United Nations’ system for sustainable development and its goals, of which the Sultanate of Oman is a part. By implementing these goals, these solutions will be appropriate and economical to solve the climate problem in the long run.
Al-Riyami also pointed out that there are many technologies in building materials that will reduce the economic costs for the citizen and the consumer, and there are many stakeholders who turn to them, but they face bureaucratic procedures, and many building permits are disrupted due to the lack of a building code and as a result refuses Requests to tend to find solutions to build the cheapest.
Environmentally friendly buildings
Engineer Ali bin Jaafar Al Lawati, vice president of the Omani Society of Engineers and a member of the Royal Society of British Architects (RIBA), in turn pointed out that the possibility of draining water in Omani buildings already exists And around this day there are many examples of this, as there were many installations that passed streams from there without any damage, and the proof of that is the Muttrah market, which is a stream of water and enters the valleys without to cause any damage to the shops, and the reason is that the ancestors in the past had an understanding and knowledge of nature and waterways and valleys and did not attack it, but today there is a human attack on the roads of valleys, ridges, mountains and their sanctuaries And if we do not coexist with nature or become accustomed to it, it is very natural to witness property damage, and in our time temperatures are rising and there is an urgent need for radical solution s to confront it.
Al-Lawati pointed out that environmentally friendly buildings are divided into two types of technologies, the first (natural technologies) costing us nothing, by directing the buildings to be built in the future to the north to take advantage of the sea breeze. , and so this method contributes to the ventilation of the buildings without using energy Electricity, and we can avoid the southwest facade because the sun’s rays fall directly on it most of the year, and therefore we should avoid putting bedrooms and halls on it farm. lace.
The second technology is (industrial technologies) which is the use of appliances that help us to be environmentally friendly and the installation of lamps with low energy consumption or appliances that work on clean energy.
Al-Lawati said: There are many solutions in the issue of climate and high temperature Air conditioners are indispensable, but there are types of air conditioners that have started to spread with water, and I think that if there was a national initiative to cool cities using this type of water engine associated with optimal landscape.And the use of optimal building materials and the distribution of vegetation between buildings, we will find that all these techniques together are able to solve the problem of the hot climate, and we has many vast areas that may just need preparation, and even mountains and hills need to be prepared in terraces and utilize groundwater to create this vegetation cover, and it is a set of mechanical and agricultural solutions and with specific technical conditions that are economical to this file can contribute. ”
