Within the process of Energy Management we can find multiple resources which help saving energy. In this post we’re going to talk about the different kinds of hardware you can come across for energy efficiency. Thanks to the latest developments of technology, energy efficiency hardware has become smarter and even more supportive to energy saving.

Did you know the energy used in the average house is responsible for twice as many greenhouse gas emissions as the average car?

The importance of managing energy can no longer be ignored. Not only you are able to save considerable amounts of money and energy but you also play a significant role in climate protection.

Lights and action!

At an estimated cost of $38 billion a year, lighting represents the largest source of electricity consumption in U.S. commercial buildings. As you can see, smart lighting stands as one of the most effective technology investments that a sustainability-minded company can make.

Implementation of meters and sensors

Two examples of implements used to energy savings in lighting are meters and sensors.

An electricity meter is a device that measures the amount of electric energy consumed by a residence or any type of building. Nowadays there are smart meters which enable you to see when you’re using the most energy and how much it’s costing. These kinds of meters provide accurate and real-time information about your energy use which helps you make important decisions regarding the building’s energy management.

On the other hand, another way of saving electric energy for lighting consists of the implementation of sensors. They can either turn the lights off when nobody is in the room or lower it when the occupants need less light while being there.

Of course you could always turn the lights off yourself but there remains the possibility of forgetting to do so once in a while. That’s when sensors come in handy, so you don’t have to worry about it.

Occupancy and vacancy sensors can cut wasted electricity used for lighting by as much as 30%.

Most common types of lighting controls

  • Dimmers. They regulate the amount of light so you can lower it when needed.
  • Motion sensors. They can detect movement and turn the lights off when there is none. 
  • Timers. They can be programmed to turn the lights on and off at specific times of the day.

JPMorgan Chase developed a plan of smart lighting and successfully carried the pilot out. At large, the whole project applied to the 5,000 U.S. branch offices could actually cut energy consumption in half which, as you can imagine, represents a large number of savings.

Saving energy is cool!

HVAC stands for Heating, Ventilation and Air Conditioning. These systems consist in air flowing through a series of ducts to be distributed to all the rooms of a building. When it’s not properly managed, an HVAC system could be in fact wasting a significant amount of energy.

Besides, this could even mean that the temperature may not be the most adequate. When a building is over-conditioned, not only is energy wasted, but comfort is sacrificed. One of the possible ways to resolve this is to guarantee that the occupants are able to make adjustments in air conditioning to get a satisfactory temperature. Doing this would also help to save energy.

Hardware helps in cutting energy bills

By combining proper equipment maintenance and upgrades with appropriate insulation, weatherization and thermostat settings, you may be able to cut your energy bills in half.

It is possible and highly recommended to set a programmable thermostat to adjust a room’s temperature at times when you’re regularly away. If you leave the thermostat set at one constant temperature, you could be missing a great energy-saving opportunity.

It’s crucial to keep in mind that when we are talking about the elements that make a building comfortable, such as lighting, heating, ventilation and air conditioning, the priority should always be the people to whom these benefit. Energy hardware works in our advantage, but we are the ones who make it work and we should do so in the best possible way.
