Renewable Energy Calculator

I'd like to find it too!

We need it too!

Has anyone found this calculator?

I'm not fully convinced it exists yet since it's not even on the v4.1 calculators page under Resources - https://www.usgbc.org/resources?LEED+Resources=%5B%22Calculators%22%5D&V....

Dear All, 

According to v4.1 do heat pumps belong to Tier1 category? If the energy will be provided in equal rate from boilers and heat pumps than we shoud calculate 50% renewable? Or this percentage has to be modified according to the heat pumps' COP? Thank You in advance for your help. 

Heat pumps are not considered renwable at all, even if they are groundsource heat pumps.

Hi everyone, I reached out to LEEDcoach/GBCI and received the following response today (4/7/21): 
"The Renewable Energy calculator is still in development and we do not have an ETA for it at this time. If you are submitting the v4.1 credit for review before the calculator is published, please provide a project-specific tabulation of renewable energy and carbon offset procurement, listing the amount of each Tier of renewable energy and carbon offsets purchased, the annual Percent Site Energy Offset for each Tier and Percent of total annual GHG emissions offset for carbon offsets, and the length of each contract."

Follow up from the 4/7/21 question - Has a Renewable Energy Calculator for v4.1 actually published to date, that LEED Online requires? If not, what steps are we meant to inform the owner / design team taking, in terms of the format of the documentation mentioned above?

Hi Adam, I have not heard that the calculator has been developed, though I have not reached out to USGBC since that previous correspondence a year ago.

Yesterday I replied to the LEEDcoach thread to ask if the v4.1 Renewable Energy Calculator had yet been developed. I received this response today: "No, unfortunately it hasn't been published yet."

The calculator is online now!

Wahoo!! Thanks Shijie :)

Has anyone managed to get the Renewables Calculator to work? There are no instructions on how to complete it and i can't seem to get anything to appear at the cell "Qualifying Annual Renewable Generation with EACs retained". Does anyone have a generic sample of the completed calculator. 

Barry, I am having the same issue! Any advice would be appreciated... for some reason it insists on dividing our qualifying generation by 10...

Just wondering if anyone has figured out about the calculator and why it changes the qualifying generation by 10?

The credit requirements are based on a 10-year timeframe. So in the absence of an entry for "Length of Contract (Years)", the calculator assumes a single one-time purchase for the "Annual Renewable Generation (for a one-time purchase enter total purchase amount)" and then divides this by 10 years. For the calculator to work correctly for Tier 1 on-site renewable energy, you should enter 10 years as the lenth of contract, which will make the "Qualifying Annual Renewable Generation with EACs retained" equal to the "Annual Renewable Generation (for a one-time purchase enter total purchase amount)".
