PoE Lighting and the building envelope, HVAC system controls are very important for safety and productivity in manufacturing facilities. We will cover PoE lighting systems, control strategies (occupancy censors, light level sensors, etc.). We will also discussed how to measure the energy performance of building envelope and HVAC systems.
Proper envelope design begins with exploration of the footprint and orientation of the building. When placed on a build site without constraints there are many opportunities, build and shape of the floor plan to minimize purchased energy use and maximize comfort. The bigger challenges occur where site conditions constrain choices, as is common in urban environments. These site planning impacts of building footprint and envelope have an impact of the design of the overall campus, e.g. taller buildings in a denser planning mode provide less solar access and daylight but may reduce travel time and related energy use.
It is technically possible to make the envelope of the building a “net zero energy element” — this is a goal that supports efforts such as California’s 2030 building performance targets. (CPUC 2011) While the fundamentals (minimize heat loss, manage solar gains, utilize daylight) are consistent across all building types and climates, the important details and design drivers change dramatically among climates based on temperature, cloud cover, and sunlight.
So where does PoE Lighting and HVAC controls come in to play?
PoE lighting systems use Light Emitting Diodes (LEDs), which are the most energy-efficient lights on the market to date, using 75% less energy and lasting 25 times longer than incandescent lighting.
With PoE lighting, the lights connect to the IT system in your customer’s building. When combined with sensors and small processors that can make decisions about lighting, these systems can provide additional energy savings
PoE design and installation
The power budget is a critical feature of PoE lighting since each cable can carry only 60 watts of power. For delivery to a large building, zone cabling can be a good option. In a zoned cable system, consolidation points act as hubs from which the cable delivers lighting, internet, and other IoT services.
Customers who switch to PoE lighting can save up to 33% in energy costs, and proponents of PoE argue that the power supply is more reliable. When standard lighting has a power outage, the lights return only when power is restored. With PoE lighting, a lights stay on for upto 120 minutes because of the battery backup system in use.
According to a new report from Pacific Northwest National Lab, commercial building owners could save an average 38 percent on their heating and cooling bills just by installing a few new controls onto their HVAC systems.
These findings mean significant potential savings for building owners who use commercial rooftop systems – but there’s just one problem: the controls aren’t currently commercially available.
In summary building with highly efficient technology will not increase the build but and will reduce ongoing operational expenses. If you would like to learn more about the Luminetworx PoE Lighting Solution contact us now.
