“Under the conditions that a large number of new buildings are not up to standard, most owners, developers and designers have not yet established energy-saving awareness, the first thing we need to do is to implement national standards in a down-to-earth manner, instead of comparing each other on the number of energy-saving rates. Building energy efficiency into a new round of performance projects and digital projects, without saving 1 kWh and 1 kg of coal."
Professor Long Weiding of Tongji University made such a loud appeal at a high-level seminar on building energy conservation held in the Shanghai government office.
Professor Long pointed out that many places in China are actively responding to the call of the state, suggesting that new buildings should save 50% energy, and some even achieve the goal of 65% energy saving. This is certainly a very gratifying thing, but at the same time it must be prevented. The "digital bubble", because so far, China does not have a unified "reference building" energy consumption standard, the so-called "energy saving 50%" benchmark is still a virtual object.
Experts have called for China to do a lot of research work, formulate a unified "baseline building" energy consumption standard, analyze the impact of regional differences and individual differences in buildings on energy efficiency, and find the same area and different types of buildings to achieve the same The cost of energy saving rate, as well as the realization of 50%, 65% of the energy saving rate in the maintenance structure of the building, lighting, heating, air conditioning and other parts of the distribution ratio, the development of forward-looking, limited building energy-saving goals.
Fahold LTD -- Products Dept. has introduced a new series of 200-480V LED Round drivers, available in 100W,150W and 240W outputs.
Each model includes input voltage ranges from 200Vac to 480Vac. The FD-150GW constant current driver offers fixed and dimmable output models. Some models are Class 2 rated.
All models feature Metal housings and are IP65 rated--making them suitable for applications subject to moisture. They offer over-voltage, over-current and short circuit protection with automatic recovery to keep luminaires performing. it has the special heat dissipation design, wehich allow to work at Ta 65°C. The drivers are UL Recognized for both US and Canada, and are CE certified.
