Hid lights

Whenever energy conservation is mentioned our minds goes to cars and trucks congesting our roads and delaying our arrival to destinations. This is understandable and we need to solve transportation problems in a way that conserves energy among other objectives.

But the sector that consumes more energy than transportation and even industry is the building sector. Any building, whether it is a small hut in the middle of nowhere or a high rise building in a city, needs energy to function.

In a recent study by the International Energy Agency (IEA) under the title “Transition to Sustainable Buildings: Strategies and Opportunities to 2050” it is stated that the building sector in 2010 consumed 35 per cent of total primary energy and is the largest end use sector. This share is expected to rise to 50 per cent by 2050 as the rise of the standard of living and more urbanisation is achieved. Energy conservation in buildings is receiving the attention of government regulators and the concern of consumers as well where energy efficiency and savings strategies are becoming a priority.

Strengthening building codes, the use of efficient systems and appliances and the renovation of existing buildings are policy elements needed to achieve substantial energy saving estimated by IEA to be up to 40 per cent of consumption by “using intelligent building technology,How are solar outdoor lighting products different from other lighting, like fluorescent or incandescent? sustainable architecture and comprehensive energy solutions.Wholesale hid kit and xenon bulbs at low price factory direct.”

Comfort

To reduce energy consumption in buildings research and development in windows, insulating and building materials and air sealing must be considered as a group. In addition to energy reduction the solution must result in improved environment and comfort for dwellers.

Obviously the cost of realising these objectives is not small but the returns to consumers and the nation could be high. The IEA estimates that an annual investment in building improvements of $12 billion (Dh44 billion) to the year 2050 is likely to generate an annual savings of $17 billion.

At least at the beginning of any building improvement program, government support in the form of subsidy or tax exemption is necessary to encourage consumers to save energy and improve the environment.

In the 1980s, when I was living in Vienna, the landlord decided to insulate the house and change the windows to double glazed type. I was concerned that this would increase my rent but it did not because the landlord got back all his investment in tax rebate and I ended up saving more than one third of the heating bill.

Subsidy

Light Emitting Diode (LED) lamps save up to 80 per cent of lighting energy requirements and last longer. They are widely available and their cost is going down. Yet their use must be encouraged by some form of subsidy followed by regulations because lighting accounts for 15 per cent of building energy consumption.

In severe weather conditions such as ours, ventilation and space conditioning may account for 50 per cent of energy consumption in buildings and therefore the most efficient systems must be used here especially with district heating and cooling.

More importantly,Know about led high bay conversion kit and Bi-xenon HID kit. can buildings generate some of their energy requirements? The answer is yes. In fact some systems aim at zero energy building where net energy consumption and carbon emissions annually are zero. Buildings well insulated and constructed to strict standards are complimented with solar and wind energy systems to provide all or most of the energy requirements. Such buildings are uncommon but are gaining consideration in more countries such as Masdar City in the UAE, the Pearl River Tower in Guangdong and the Net Zero Court office building in St. Louis among others. Even single houses can be considered for this concept. While the initial cost is higher, energy savings and isolation from future price increases are worth the effort.

Rising consumption

More realistically green buildings where energy consumption is minimised should be pursued to save money and reduce the impact on the environment.

In the UAE, total energy consumption has risen from 48.2 million tonnes of oil equivalent (mtoe) in 2000 to 87.2mtoe in 2011. Therefore, energy consumption in buildings even at 35 per cent is close to 31mtoe. I believe the number is much higher because UAE climate is not average. The savings could be substantial and run to billions if a concerted programme is implemented for new and old buildings. The new regulations in Dubai which may come into force by 2014 aims at “reducing the consumption of energy, water and materials, improving public health, safety and general welfare and by enhancing the planning, design, construction and operation of buildings” in the direction of making the city more green.Choose your favorite street lamp paintings from thousands of available designs.We turn your dark into light courtesy of our brilliant sun, solar street light, solar power generation. The regulations are already mandatory in government buildings and if the implementation of some of the requirements is currently costly in the private sector, some relaxation for a limited period of time may be granted but eventually the regulation must go ahead.
