Reducing Commercial Energy Usage with Thermal People Counting

Commercial buildings lose billions of dollars every year on energy.  According to the U.S. Department of Energy, office, retail, and service buildings are the biggest offenders wasting over 30% of energy consumed.  Energy inefficient buildings are not only expensive but increase harmful emissions that affect our planet.                                      

Some property owners try to take a stab at reducing their energy consumption, but cannot correctly implement an energy-savings system without the right data. Others may not understand exactly where their biggest energy expenditures occur. No matter the issue, the fact remains that commercial energy usage must be reduced to ensure a brighter future. 

Businesses could save money, curb emissions of global warming pollutants, reduce our oil-dependence and cut energy consumption 23 percent by 2020, by taking practical steps to use energy more efficiently.”

Only About One-Third of People Feel Their Office is Environmentally Friendly*

It’s not just property owners who have taken notice of how buildings operate. According to green building professionals, employees who work in an energy efficient environment are more productive. This means reducing commercial energy usage will not only save money on utilities – but also could yield higher revenue for your company.

The Link between Thermal People Counting and Increased Energy Efficiency

Thermal people counting allows you to accurately track how people utilize your building, empowering you with data to adapt energy usage to match occupant behavior, resulting in reduced usage, for example, of heating, cooling, ventilation, and lighting systems.

Thermal detection devices integrate into other commercial systems to unobtrusively detect and count people by their body heat. The analytics used by these systems captures occupancy and usage trends from one space to the next.

Thermal-Based People Counting Optimizes Building Utilization & Reduces Operational Costs

Acclimatizing an Empty Building Results in Empty Pockets

Energy consumed to heat and cool buildings account for cooling account for almost 50% of commercial energy usage within buildings.  But realize you’re also not in the clear if you are using automatic building management systems, because most HVAC schedules aren’t correctly tied to ever-fluctuating occupancy hours.

Thermal people counters allow you to track where people are in your building, and at what times, so you can create an up-to-date, energy-efficient heating and cooling schedule that reduces both your utility bill and carbon footprint.

Power Down Computers. Power Up Savings.

If the cost to keep a person employed was 433% more than their output, they probably wouldn’t be employed very long at all. So, why keep a computer on when it is not in use? Computers cost about 433% more in energy when powered up 24 hours a day versus being turned off on an intelligent schedule, according to the Office Equipment Energy Savings Calculator.

When you deploy a thermal people counting system, you can track exactly when computers in certain areas are used; giving you the analytics you need to align operational efficiency with actual usage. 

And, don’t just think “PCs” when you think of computers. Things like marquees, check-in systems, digital screens, and more can all be powered down when there is no traffic in the area – reducing energy consumption and lowering energy costs.

Are the Lights on When Nobody is Home?

Lighting costs commercial buildings a lot of money. In fact, lighting is the third highest expenditure for office, retail, and service buildings according to the U.S. Energy Administration. While some try to manage their usage by powering down lights at certain times – most lighting schedules don’t match actual human usage and behavior.

An integrated thermal people counting system can make automated schedules more efficient, so you can have constant intelligence to track shifts in utilization patterns.

How Smart is Your Building?

To make your building smarter, greener, and more efficient – you need an accurate picture of occupant behavior and energy usage so that you can set forth a plan based on these trends.

Thermal people counting systems from Irisys are perfectly suited to deliver a complete data picture – from the overall building and down to floors, specific zones and workspaces.
