At Airthings, we are passionate about sustainability. We think it is important to understand the impact we each have on the environment and look for ways to reduce this. We strive to not only reduce our environmental impact but also help our customers reduce theirs. 

Product-feature-icons_blue_Reduce energy (1)This is why we developed an energy savings calculator. By providing some facts about your building, you can get an estimate of how much energy you can save with the new Balance for Business. Even though it is just an estimate, we try to give you an accurate picture of potential savings based on where your building is located. 

The estimate is based on regional averages for energy use per area of floorspace. From this, we are also able to estimate cost savings based on regional electricity prices and the equivalent savings in terms of carbon emissions based on the regional electricity mix. Understanding your carbon footprint can be tough. That’s why we also converted the carbon equivalent to flights from London to New York. 

What does my estimated energy saving mean?

You may be wondering how exactly Balance for Business can cut your electricity bills. The key is stopping the leakage of air from your building. No buildings are 100% airtight because of differential pressure. Meaning that air is able to “leak” out of doors, windows, and small gaps all over your building. And just as with a leaky pipe, costing you money by wasting water, these air leaks mean conditioned (heated or cooled) air inside your building can leave, allowing space for outdoor air to come in.

This is all based on differences in pressure between the inside and outside. Balance for Business essentially plugs the holes and stops the leaks by eliminating the difference in pressure, effectively keeping indoor air inside and outdoor air outside. This will cut down on your need to continually heat or cool new air entering your building, saving you money and reducing your impact.

Want to find out how much you can save? Check out our new energy savings calculator. Once you get the initial estimate, contact us for a personalized explanation of how we can help stop air leaks in your building. 

 

Balance for Business Calculator

How did we get our numbers: 

Electricity Price (from EU dataset1): 2019 data Euro/MWh for most countries; Argentina, Australia, Brazil, Canada, India, Indonesia, Japan, Mexico, Saudi Arabia, South Africa, South Korea, Switzerland estimates were from older data: Data was converted to Euro/kWh by dividing by 1,000 and then converted to USD/kWh by multiplying by 1.1199 (the exchange rate in 2019)2.

Energy Intensity (from this3 paper, adjusted based on these4 changes): regional estimates based on 2000 numbers and the index changed from 2000 to 2019 [data is given for total energy intensity not just electricity intensity but using these numbers as baseline assumption since that is also what we used for CO2 calculator]. When data isn't available for specific regions, the world average was used. 

Environmental impact (mainly from two sources, for the different countries in EU5 and the rest of the world6): estimated carbon dioxide equivalents per kWh of electricity produced in different countries, converted from gCO2eq/kWh to kgCO2eq/kWh by dividing by 1000. China, India, Southeast Asia numbers were used. For all other countries not listed (Japan, South Korea, Russia, Turkey, Switzerland, South Africa, Saudi Arabia, Mexico, Canada, Australia, Brazil, Argentina), world average was used. For the US, data from EIA were used7
Carbon dioxide intensity for total generation for all sectors (mt/MWh): 0.401
Converted to kg/kWh → multiply by 1000kg/mt*mwh/1000kwh→ 0.401 kg CO2eq/kwh

Carbon emissions of flight from London to NYC were taken from this article in the Guardian8. The total emissions from the calculator were divided by estimated emissions per flight to get an estimated number of flights.
