A crowd-based 

dictionary.

Definitions abound, new connotations and usage of words in the energy-efficient built environment is not always harmonised. We feel clarity and harmonisation of the jargon is a foundational step towards speaking the same language and adds crucial layers of clarity, transparency and accessibility to this sector. Hence, the encyclopenergy dictionary supports the encyclopedia by unpacking the built environment jargon and provides definitions in a glossary as words’ explanations crystallise. Should you feel like a listed word is wrongly defined, lacks reference, or you simply have something to comment on, feel free to engage in a discussion by clicking on the specific word’s name. This will redirect to the word’s passport, where the community forum takes place, improving the description accuracy to harmonise and standardise shared definitions.
