Energy Performance of Buildings – what a large and very modern subject.
If the 20th century was called the “century of speed” our actual one the 21th century can be called the “century of hiperspeed”
Every thing is made in rush and also the calculations for Energy Performance of Building are made with Aplications , in a high speed.This is not a bad thing in first but can make us as energy auditors to forget the basics , the PHYSICS of BUILDINGS and INSTALATIONS.
This site invite you to take it slow and THINK and MEDITATE about the fundamentals of PHYSICS of BUILDINGS and INSTALATIONS.

Energy Performance of Buildings ( EPB ) - calculations and tutorials for energy auditors
My name is DIMA AURELIAN , from Bucharest , Romania . I am engineer , physicist , programmer and energy auditor for buildings . More dates about me you can find in page About . In 2023 I created an Application for calculating Energy Performance Certificates , Energy Audits and others Energy Studies and Raports for buildings . After I create the application I start to sell and deploy it at different energy auditors from my country , Romania .
Because I am a very serious person and I do not like to take things in RUSH , I spent betwin 7 – 10 hours with eatch energy auditor to learn him how to use the application .
What I found in this years , working with them is that they FORGOT PARTIALY the PHYSICS of BUILDINGS and INSTALATIONS.
This was for me a big surprise . How can they work without knowing VERY WELL the PHYSICS of BUILDINGS and INSTALATIONS.
Here are the explanations :
1.Many energy auditors do not have this job as the primary one , it is the second or the third job for them . They do not have much time or energy to refresh their knowledge.
2.At the beggining , when they graduate a difficult exam for energy auditors , they knew well and understand let’s say more than 60-70 % of PHYSICS . In time because they use Applications for calculating energy performance of buildings they forgot large part of PHYSICS . Now , a part of them , are like robots and know only the cells of the Applications where to insert the dates and the Applications do all the rest and they get the Energy Certificate , Energy audit or other Studies or Raports .
As a countermeasure to those things I created in the website , of the application I made , a few more pages to try to explain as much as I can the PHYSICS of BUILDING and INSTALATIONS for romanian auditors . Also I created some tutorials to present in more detail energy performance calculations for buildings . After a few month I realized that the same problems have a lot of energy auditors of buildings from the whole world.
Energy Performance of Buildings ( EPB ) , calculations and tutorials for energy auditors is a very large topic . This are the reasons that made me to create this website.
I hope that informations from this website will help you to understand more from PHYSICS of BUILDINGS and INSTALATIONS and become a better energy auditors . I hope will help you to understand more of the calculations for energy performance of buildings . I hope , this website about energy performance of buildings (EPB) – calculations and tutorials for energy auditors , will help you to become more confident to work complicated buildings with many complex and modern instalations.
I hope that informations from this website will help people who are interested to become energy auditors for buildings in the process of learning , or for architects , installation engineers who are interested in the field of Energy Performance of Buildings.
