This is an exceptionally well-maintained 1977 Toyota Land Cruiser.<\/strong><\/p>\n The owner is asking 5,900 EUR for it, which might seem affordable. But nowhere in the ad does it mention that it consumes 25 liters of petrol per 100 km and that the engine, body, chassis\u2014well, most of it\u2014will probably need to be replaced soon due to severe wear and tear.<\/strong><\/p>\n In summary, it’s a fairly cheap car to buy but insanely expensive to use.<\/strong><\/p>\n It’s exactly the same with industrial doors. You have a purchase price that’s easy to compare, but then there are hidden costs that depend on how well-designed, insulated, and sealed the door is.<\/p>\n Some doors last for 30 years, while others need to be replaced after five. If you’re unlucky, you might need to buy six cheap doors to get the same lifespan as a good one.<\/p>\n In this way, the purchase cost and capital cost are linked to the lifespan of your door.<\/p>\n Buying the right door is therefore an investment that can provide future returns.<\/p>\n\t\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t If a door lasts for 30 years, the cost of the door and installation is only a small part of its total operating cost.<\/p>\n\t\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t The biggest expense goes toward paying for all the heat that escapes through the door when it’s closed. How large that cost is depends on how well-insulated the door is.<\/strong><\/p>\n We have replaced poorly insulated old doors that let through 15,000 kWh of heat energy per year. A new 4\u00d74 meter Torverk door lets through less than 3,000 kWh annually.<\/p>\n Consider the truck workshop we helped in 2019 to replace seven of their old doors with Torverk doors. There was nothing wrong with the old ones, but since trucks had become slightly taller since the doors were installed in the ’80s, they needed higher folding doors.<\/p>\n For us, it was a completely ordinary assignment. We did the job and went home.<\/p>\n Years went by, and the truck workshop carried on as usual. But in December 2023, the property manager reviewed the company’s district heating consumption.<\/p>\n Before the company replaced the doors, their district heating consumption was steadily around 640,000 kWh per year. After the replacement, consumption dropped to 550,000 kWh.<\/strong><\/p>\n The seven Torverk doors reduced the workshop’s district heating cost by about 9,000 EUR per year. Since the doors cost 31,820 EUR including installation, they paid for themselves in just three years.<\/p>\n\t\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t When heat energy travels through the material from the warm to the cold side, it’s called transmission. The measure of how much heat a door lets through is called the U-value<\/strong>. A high U-value means you lose a lot of heat energy through the door’s construction.<\/p>\n The tricky part is that different door manufacturers measure U-value in different ways. “Best average” is, for example, a “feel-good measure” calculated by looking at how much heat energy can pass through the most well-insulated part of the door panel.<\/p>\n But “best average” has nothing to do with reality, since the real U-value occurs when the door is installed\u2014including seals, windows, pedestrian doors, and frame connections\u2014all of which contribute to lowering the actual U-value. Therefore, you should always ask for the U-value of an installed<\/strong> door.<\/p>\n\t\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t All closed doors also have air leakage.<\/p>\n How much air a door lets through depends on the quality of the sealing system and the pressure difference between indoor and outdoor environments.<\/p>\n The measure of air leakage is called the T-value<\/strong>, and it’s measured in a laboratory environment.<\/p>\n\t\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t Every time the door opens, heat escapes and cold enters.<\/p>\n The difference between different door brands and types is almost negligible, but you can minimize air exchange with flow-optimized automation, which brings us to logistics.<\/p>\n\t\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t A major expense associated with your door is all the working time lost waiting for the door to open and close. If a forklift has to wait ten seconds, ten times a day, seven days a week, 47 weeks a year, that’s almost ten hours of lost working time.<\/strong><\/p>\n The equation to calculate passage cost is:<\/p>\n Passage Cost = Number of Passages \u00d7 Passage Time \u00d7 Time Cost<\/strong><\/p>\n By automating opening and closing with sensors and motors, you can reduce the waiting time every time someone enters or exits the building.<\/p>\n Bruno Bergmar p\u00e5 Bj\u00e4lbo Tr\u00e4dg\u00e5rd i Sk\u00e4nninge uttrycker det p\u00e5 ett enklare s\u00e4tt: \u201dEn ports roll \u00e4r att inte vara i v\u00e4gen\u201d.<\/p>\n Varje \u00e5r producerar Bruno tio tusen ton potatis.
