How are Digital Twins used in Building Automation?

By David Koerner on Oct 22, 2021 10:10:33 AM

What is a digital twin? 

Let’s start with a definition: A digital twin is a virtual model of a real-world object or space. It can be a digital replica of an object in the physical world, such as a jet engine or wind farms, or even larger items such as buildings or even whole cities. Within the built environment, a digital twin is a digital or a web-based representation of a physical building, system, or sequence, scaling all the way up to a city or utility grid. A digital twin can represent everything within a building and can offer real-time data about how those assets are performing.

A Commercial Lighting Control System Built for the WELL Building Standard

By Sarah Baker on Sep 3, 2019 11:11:27 AM

Re-lamping and LED retrofit projects are popular methods for reducing energy costs. Re-lamping can be an effective source of energy savings – but there are even larger opportunities you may not have considered. Recent advances in cloud computing technology means that an automated lighting system offers larger savings opportunities and an even shorter ROI than re-lamping or LED retrofits. Plus, smart lighting systems offer benefits like meeting WELL building standards for a greener, healthier building.

Our Advanced Lighting system considers local weather, building orientation and geography, and occupancy status to adjust the lights, ensuring that no energy is wasted. Our interconnected system also ensures you're never left in the dark – and we offer remote scheduling and control, too.

6 Keys to an Effective Restaurant Building Management Solution

By Sarah Baker on Aug 20, 2019 6:18:00 AM

 

Restaurants are the most energy intensive commercial buildings in the United States, according to the Energy Information Administration, and they consume nearly three times the energy of the average commercial building per square foot. Special equipment, lengthy hours, and sheer demand create much of this consumption.

In addition to their costly energy consumption, restaurants are particularly prone to building pressure imbalances. A building pressure imbalance – either negative or positive – often manifests itself as difficult-to-open doors. If building pressure stays out of balance, restaurant buildings can suffer from a number of other symptoms, including trouble maintaining room temperatures, underperforming kitchen hoods, odors due to infiltration, back drafting water heaters (look for moisture, corrosion or melted plastic on top of the top of the heater), and condensation dripping from ceiling diffusers.

Here are some ways a smart building automation system can diagnose, solve, and prevent issues like pressure and temperature imbalances in restaurant buildings – while reducing energy bills by up to 50% in the process.
