The Importance of Energy Use Intensity in Improving Energy Efficiency

Do you believe you studied your commercial enterprise is spending too much on strength? In that case, you need to discover a manner to reduce your power intake and make the maximum of your power charges. There are loads of options that allow you to. But, you have to first apprehend electricity use depth and its role in improving your power performance. You undergo your constant overhead prices and get stumped by using how a lot it’s miles. What do you do? You locate approaches to reduce them down, of route. Energy charges soak up one of the biggest percentages of your employer’s month-to-month finances. Which is a good factor due to the fact not like other components consisting of worker bills and commercial enterprise operations, power expenses may be reduced. Business buildings contribute more than twenty percent of the full power consumption of the usa, a mean thirty percent of which goes to waste. Just knowing your constructing’s general electricity intake cannot help you optimize power efficiency. President of wecompete energy ceo mr. Is living states, “with information of your energy use depth, you could determine whether your building is using too much energy for its length and assist you decide how much of your consumption you want to lessen.”

what’s energy use depth? Electricity use intensity (eui) measures a constructing’s energy performance. It’s far expressed as a feature of the building size via figuring out annual electricity usage per square foot of your building. Truly put, it may be computed through dividing your overall energy intake for the yr through the entire floor location of your constructing. There are kinds of euis: the web page type and the supply kind. The website online type eui is used to measure the quantity of energy utilized in a building even as the supply type eui represents the whole quantity of electricity used to run a company and its operations; this includes energy used for delivery and transportation procedures. The way to compute for eui? Now that we’ve got established that eui is electricity use consistent with rectangular foot according to year, it’s time to learn how to compute for it. Compute for the eui by using dividing gross strength applied in a yr, expressed in kilowatt-hour or kilo-british thermal units (kbtus), over overall rectangular photos of the constructing. For example:

you own a two-tale constructing with the main floor measuring around 20,000 rectangular ft and the second-ground degree 15,000 rectangular toes. Your constructing ate up a total of two,250,000 kilowatts for the 12 months. Convert your intake in kilowatts to kbtus. You may gain the kbtus in case you multiply your overall power consumption by 3. 412 (1 kilowatt is equal to a few. 412 kbtus). Multiplying 1,550,000 kilowatts through three. 412 offers us an annual strength use of 5,288,600 kbtus. Now, compute for the whole vicinity of your constructing. In this example, it’s miles 20,000 rectangular ft + 15,000 rectangular toes. That offers us 35,000 rectangular ft. Eventually, get your eui by means of dividing your annual power use in kbtus with the aid of your overall area in rectangular feet. That would be 5,288,600 kbtus in step with year over 35,000 rectangular feet. The eui of your constructing is 151. 1 kbtu/ sq. Feet.

What causes variations in eui? A low eui signifies properly strength overall performance. Presently, no wellknown determines whether an eui is right or no longer because euis vary for several motives. Constructing kind, climate conditions, running hours and quantity of occupants, are the motives at the back of the versions of eui. Constructing kind – supermarkets have the highest euis. Hospitals have eui values which might be three times better than that of educational establishments. It may be due to the fact extra system is being utilized in hospitals and lights is turned on for nearly 24 hours an afternoon. Weather conditions – versions in temperature consequences to exceptional heating or cooling necessities. There are variations in heating and cooling charges in step with location. Those differences must be taken into consideration whilst computing for the eui value. Operating hours – longer running hours approach greater lighting fixtures and equipment usage ensuing to better energy consumption and eui price. Quantity of occupants – euis are measured the usage of the entire annual electricity consumption and the ground vicinity of a constructing. Between two comparable homes with the identical ground location however a extraordinary quantity of occupants, the building with the better range of occupants would have a higher eui value. How does eui enhance strength efficiency? Eui determines whether your actual annual power intake exceeds the strength consumption required for the dimensions of your constructing and its occupants. It may be used as a baseline whilst quantifying the amount of energy you must lessen. Eui leads you to recognize your electricity overall performance higher. Despite simply basic know-how of eui, you can use it to evaluate the energy efficiency of buildings just like yours and decide areas where you could nevertheless make improvements. Be a part of the 60 billion dollar savings in power charges with the aid of taking part in strength management packages. Take the proper steps in the direction of lower electricity charges!
