The new thermal regulation UNI EN ISO 52016-1: 2018 entered into force on 1st March 2018, replacing the UNI EN ISO 13790, and dismissing the old seasonal and monthly calculation method. But what distinguishes the new legislation?

• A new dynamic hourly calculation method for heating and cooling;
• A functional integration of the calculation method of thermal loads (winter and summer);
•  More reliable results as it considers the real conditions of use of the building;
• An understandable, reproducible and transparent model.

• The thermal inertia of the building envelope.
• The variation in the conditions of use of the rooms.
• The solar gains.
• The evolution of external climatic conditions.
• The variation of temperatures in a specific place throughout the day.

Diatherm was born from a research project between Diasen and the Department of Industrial Engineering and Mathematical Sciences of the Polytechnic University of Marche Region. It is a free online software to perform thermal calculations in line with the new dynamic hourly calculation model proposed by the standard EN ISO 52016- A simple, fast and reliable online application that requires the insertion of generic and simple data.
The software aims to respond to the biggest challenge, for the present and the future, in the construction industry: to improve living comfort and the quality of living as much as possible.
The software, aimed at the network of designers (engineers, architects and professionals in the sector) allows to identify the best technological solutions for summer and winter thermal insulation, by simulating the energy consumption and environmental conditions of the building in its real use, taking in consideration the climatic conditions of the territory,

The "perception" of the microclimate determines the real level of thermal comfort of a living space. In this context, the environmental variables to be considered are several: the air temperature, the possible formation of mold and condensation, the type of activities carried out inside the home, the disparate sensitivity of people to thermal comfort. Therefore, when designing a building, it is important to carefully study the variables affecting thermal comfort.
