This isn’t by any means a definitive science, but there is a method to provide a rough estimate on the loss of energy using the following formula. Yes…we googled this one as Einstein was unavailable to assist;
\[
Q = \frac{A \times U \times \Delta T \times t}{1000}
\]
Where:
– \( Q \) is the energy lost (in kWh).
– \( A \) is the area of the door (in m²).
– \( U \) is the thermal transmittance value (in W/m²K).
– \( \Delta T \) is the temperature difference between inside and outside (in °C).
– \( t \) is the time the door is open (in hours).
Given the variation in these factors, energy loss can range from hundreds to thousands of kWh annually per building, depending on the specifics.
There are some resolutions available to support the reduction Energy Loss and Heating Bills:
1. **Install High-Speed or Automatic Doors:**
– **High-Speed Doors:** Reduce the time doors remain open, minimizing heat loss. Our High Speed Door range is diverse and with many different configurations available, there is a solution for anyone. https://www.arrow-industrial.co.uk/products/arrowspeed-high-speed-rapid-roll/
– **Automatic Doors:** Ensure doors close promptly when not in use.
2. **Use Air Curtains:**
– Air curtains create an invisible barrier of air that reduces the mixing of indoor and outdoor air, limiting heat loss even when doors are open. Our #Enershield Air Barriers are an incredibly innovative way of providing this solution. https://www.arrow-industrial.co.uk/products/arrowair-enershield-air-barriers/
3. **Improve Door Insulation:**
– Insulating doors can significantly reduce heat transfer, especially in older buildings.
4. **Implement Dock Seals or Shelters:**
– For loading bays, dock seals or shelters minimize gaps around trucks, reducing heat loss. We have access to all manner of loading bay equipment and accessories. https://www.arrow-industrial.co.uk/products/arrowdock-loading-dock-equipment/
5. **Employee Training:**
– Educating staff on the importance of keeping doors closed can lead to behavioural changes that reduce unnecessary heat loss.
6. **Regular Maintenance:**
– Ensuring doors, seals, and heating systems are well-maintained can prevent energy waste due to inefficiencies. This is probably one of the most important elements and the easiest and let’s face it, cheapest way to help. Regular maintenance can mitigate the need for expensive repairs when things have been allowed to get out of control. Arrow have centres across the country, available 365 days a year with skilled engineers, trained to service and repair an manner of industrial door. https://www.arrow-industrial.co.uk/services/service-repair/
Potential Savings:
– By implementing these measures, you could reduce your heating energy consumption by 10-20% or more, depending on the current inefficiencies. For large facilities, this can translate into significant financial savings, potentially in the tens of thousands of pounds annually.
