Impacts of Improper Sizing of Harmonic filter

For those tasked with maintaining quality power at a commercial facility facing harmonics issues, the optimal approach involves the installation of a series of active filters. In the application of these filters, a meticulous examination of harmonic control requirements is crucial, and sizing the filter appropriately becomes pivotal in resolving the problem. It is unnecessary to address every amp of harmonic current originating from nonlinear loads, leading to significant savings in required filter size.

Why do builders invest in 8VA/sqft when the actual need is just 4VA/sqft?

The conventional understanding has long dictated an electrical rule of thumb: 8VA/sqft. However, as we find ourselves well into the 21st century, it becomes increasingly evident that this standard, rooted in the 1980s, is outdated and in need of reevaluation. One might wonder, why persist with 8VA/sqft when technological advancements have transformed the landscape of energy efficiency? The shift from cathode-ray tube computer (CRT: 250W) to light-emitting diode (LED) display computer (60W), the replacement of tungsten bulbs with LED lighting, and the evolution of chiller efficiency from 1.2 kW/ton of refrigeration (kW/tr) to a mere 0.4 kW/tr are testament to the progress we’ve made in optimizing energy consumption.

Flood Risk Management: How to do it right?

Flooding events are on the rise across the world, in fact there is an increasing trend in the number of disasters and their total economic impacts. Floods have the greatest damage potential of all-natural disasters and affect the greatest number of people. Flood risk ignores borders, rainfall in one location can correlate to flooding in another. On a global basis, there is evidence that damages resulting from flooding are on the rise at an alarming rate. It is estimated that flooding affects more than 250 million people globally each year and results in over 1000 crores in economic damages. This is a trend that will continue unless concerted actions are taken to mitigate the impacts from flood risks.

How Developers Can Build Net Zero Water?

The persistent problems of drainage smell, clogging, and flooding in urban spaces demand a critical reassessment of the design approaches. The conventional methods that we have been relying on are clearly falling short, and it’s time to acknowledge that. Zero discharge buildings are not just a trendy concept, they’re a necessity. The stench from poorly managed drainage systems and the inconvenience caused by incessant flooding are warning signs that the designs are out of touch with the urgent needs of the modern world. It’s time to break away from the status quo and embrace sustainable drainage solutions.

Navigating the World of Carbon Credits: Compliance and Beyond

Climate change has necessitated global action to reduce greenhouse gas emissions. A pivotal tool in this fight is the concept of carbon credits, which come in various forms and are integral to both regulatory and voluntary markets. In this blog, we’ll explore the nuances of carbon credits, focusing on Compliance Carbon Credits, Certified Emission Reductions (CERs), Emission Reduction Units (ERUs), and Verified Emission Reductions (VERs).

Why Is High Tension Distribution Essential on a Campus?

Electricity is initially generated at 11 kV and then stepped up to higher voltages for long-distance transmission. The power travels through a network of high voltage lines into the grid, which connects to cities through substations. These substations step the voltage down to 11 kV for distribution to load points via a network of lines. The distribution network includes feeders that branch into subsidiary lines, delivering power to various locations. Transformers at load points further reduce the voltage (LT), providing the last-mile connection to individual customers at either 240 V or 415 V. Feeder lengths vary based on urban or rural areas, with longer feeders leading to potential low voltage issues at the consumer end.

Rainwater Harvesting: Paving the way to a Net Zero Water Campus 

In our current era, we’re facing significant challenges due to climate change and the increasing scarcity of water on a global scale. It’s crucial that we adopt sustainable practices to conserve water and minimize the negative impact on our environment. One such eco-friendly solution is rainwater harvesting, which has the potential to lead campuses and communities towards achieving a ‘net zero water’ status.
