Dubai buildings unlock up to 80% energy savings with simple pump swaps

概观

这种情况

有时需要一些简单而具体的不快租户连接之间如何解决自己建设和贵国政府对改善建筑物的能源使用的目标点。

迪拜政府的目标是到2030年将其改造建筑物30000〜帮助减少30％的城市的能源需求。它是在阿拉伯联合酋长国节能节水的几个重大举措之一。由于快速的步伐在该技术一直在进步，现在的城市访问解决方案，使中宇如此激烈的节约。迪拜在过去的几十年里主要的快速增长后，需要对这些解决方案已经变得越来越明确在最近几年。

“This city was built very fast – but at the time there wasn’t a focus on quality design, quality construction, quality materials, operation and maintenance,” says Charles Blaschke, founder and CEO of Taka Solutions – an energy consulting company specialised in engineering, technology and finance optimisation for commercial buildings based in Dubai.

“而这些又大又漂亮的建筑大多是玻璃。在沙漠中，我们在极端气候。迪拜是阳光明媚的一年364天。雨几乎为零。它总是有一个非常强烈的太阳与太阳辐射击中建筑物。玻璃建筑消耗了大量的能源。在时间，精力很便宜，所以人们不注重节能。他们只想舒适的建筑物。‘Let’s put in a bigger AC system, a bigger pump system, to ensure that no matter what happens – fully occupied or not – let’s make sure it’s more than enough to keep the building cool.’ So all over Dubai, the pumps and AC systems are usually much bigger than they need to be. They’re not operating for maximum efficiency.”

靛蓝塔的“喷气发动机”

Indigo Tower is one of those buildings constructed in the rush and with a way-too-large AC system. It is a typical, mid-sized building around ten years old in one of Dubai’s developments north of the city. It has eight stories of apartments. The pump room is on the roof – just over rooms 812, 813 and 805. The residents in those rooms particularly described the noise above their ceilings as “constant – like a jet engine.”

“人们试图生活和睡眠有 - 这是一个公寓楼。所有他们只能听到这个响亮，齿音，永远不会走了，”查尔斯·布拉施克说。“由于交流在这个炎热的地区要求，AC字面上运行一年24/7，365天。有没有他们很舒适，并且具有与他们在建设经验的问题在今年的一个小时。有一个巨大的驱动器来解决这个问题“。

靛蓝塔的主人，H＆H物业管理和开发，在其两个其他建筑物，绿塔（商业）和猎鹰大厦（住宅）也经历了不寻常的电力成本较高，在迪拜的德拉地区。投资组合经理瓦西雷斯Vatistas怀疑它也有与泵和冷却系统的事情。18luck手机客户端下载就在这个时候，他的公司与塔卡解决方案取得了联系。

格兰富能源检查

Taka Solutions worked with Grundfos to determine the problems around the existing HVAC (heating, ventilation and air conditioning) pumping systems. A Grundfos Energy Check determined that the buildings were equipped with oversized pumps, inefficient operation and poor balancing in their constant, primary chiller systems. The pumps ran at constant speed. The Delta-T (the temperature difference between the supply and return chilled water) was only 1 degree Celsius – which in a building’s chilling system means extreme inefficiency.

因此，推荐格兰富改变为紧密耦合，端吸与变频驱动泵 - 智能NB-E的泵。18luck手机客户端下载这些可以提供精确的流量要求，以冷水机组无损耗，提高增量T到五摄氏度。一个简单的交钥匙解决方案。

“When we saw that the pumps in these three buildings – Indigo, Green and Falcon – were wasting energy, were vibrating, were causing noise issues, weren’t reliable and had savings potential, we saw this as a real winner and equipment to replace,” says Taka Solutions’ Charles Blaschke. And then Taka Solutions offered to replace the old pumps …免费。

“这是一个事实，即我们团队很多人都对此持怀疑态度，” H＆H的瓦西雷斯Vatistas说，基于性能的合同。但没多久，了解它是如何工作的。节约能源将支付泵升级。18luck手机客户端下载

The solution

“我们的想法是非常简单的，”他说，基于性能的合同。“塔卡解决方案具有基于储蓄，这些建筑将执行的投资回报。这是一个双赢的局面，因为我们得到了国家的最先进的新设备。我们扩大我们资产的使用寿命。我们可以给我们的居民，这是我们在H＆H真正重要提供一个更好的环境。和塔卡解决方案会从节约能源超过一些年来的钱回来 - 这取决于我们有协议“。

立竿见影的效果

H＆H看到的结果几乎立即。在靛蓝塔，水泵以前使用的每小时36千瓦。18luck手机客户端下载升级后，他们7-10千瓦/小时之间。现在，两年的运作，他们用81％更少的电力比以前。此外，泵的效率是不是只有更18luck手机客户端下载好，也是整个空调系统的效率。在实际的投资回报时间仅仅八个月。

“我们所做的一切,我们只支付的年代avings we generate,” says Charles Blaschke. “We have to ensure that a project is designed for the long term. Working with quality partners and equipment suppliers like Grundfos across our projects is key, because it gives us peace of mind. We know we can trust them. We know what they put in is right. It’s going to be the right optimised solution. Not just today, but also tomorrow.”

结果

The numbers on the other two building retrofits in 2018 tell similar stories. Falcon Tower cut its pumps’ electricity consumption by 46% and Green Tower cut its use by 57%. Overall, the buildings cut their total energy savings – including that from chillers, ventilation and lights – between 20-25%.

“I’m really keen to say that it was worth it,” says Vasileios Vatistas. He adds that not only was it worth it for his company, but the residents in all three buildings are experiencing more comfort. And the eighth storey rooms below the pumps at Indigo Tower? All is now quiet – no more complaints.

在迪拜类似改造的潜力是巨大的。“这将注意力集中到了大量的贡献改造老低效泵将满足迪拜的2030愿景在水和能源消耗降低了30％的是很重要的，”查尔斯·布拉施克说。18luck手机客户端下载他补充说，泵的改造也向联合18luck手机客户端下载国可持续发展目标SDG6和13贡献 - 水和气候。

“It starts with one building. One building at a time,” he says. “We see these buildings as locked potentials of value. Energy savings, carbon savings, money savings – they are all sitting in these buildings almost untouched and untapped.

“他说，‘现收现付您节省’的商业模式，让楼宇业主在没有资金成本改造他们的HVAC系统，是解开他们的建筑长期价值的诱因。

“All we need to do is get to them and almost open the valve,” he says. “It’s not hopes and dreams or something that’s not feasible. It’s right there, and it’s very simple to achieve.”
