Overview

## What Energy-Data.io Degree Days does

Degree days are the standard input for weather-normalizing energy consumption, and this app returns them on request. Heating and cooling figures come back for a named city or a pair of coordinates, over a chosen date range, calculated against whatever base temperature the work calls for. Outside temperature data is available the same way.

The result is plain numbers ready to drop into a savings calculation or a measurement and verification report, which removes the spreadsheet lookup that normally comes first. The underlying source is the weather data engine behind Energy-Data.io, developed by Onyx Dynamics.

### Who it is for

Energy managers, consultants, and auditors who normalize consumption data against weather conditions.

### What stands out

Base temperature is a parameter rather than a fixed assumption, so figures can follow the convention a given report uses.

## Where Energy-Data.io Degree Days is listed

Energy-Data.io Degree Days is listed in the ChatGPT apps directory only. Onyx Dynamics LTD has no connector under the same domain in the Claude directory; 392 of the 3,150 products here are on both marketplaces, and this is not one of them.

ChatGPT apps are built on MCP, and the same server can back a Claude connector, so the absence is a distribution decision rather than a technical one.
