Energy efficiency study of an academic classroom of an educational center under NOM-007-ENER-2014 and NOM-025-STPS-2008

The energy efficiency of an academic classroom is presented as an important alternative to avoid the excessive use of artificial air conditioning systems, thus reducing energy consumption and the environmental, social and economic impacts derived from said consumption. Currently, the official Mexican standards NOM007-ENER-2014 and NOM-025-STPS-2008 are used, efficiency and lighting conditions in buildings. The official Mexican standard NOM-0076-ENER-2014 establishes the levels of energy efficiency in terms of electrical power density for lighting with which lighting systems for general use of new non-residential buildings, extensions and modifications of existing ones must comply existing. While the official standard NOM-025-STPS-2008 establishes the minimum lighting conditions that every workplace must comply with. With the above, it turned out that based on the materials that currently make up the classroom envelope, it does not meet the standards established by the norm, which directly requires establishing a new design of the envelope that leads to reducing heat gains towards the interior of space.
