International. Air conditioning has become one of the most determining factors in the energy performance of commercial and residential buildings. In a context of rising energy costs and more demanding environmental goals, the efficiency of heating, ventilation and air conditioning (HVAC) systems acquires a strategic role in the operation of buildings.
Globally, buildings account for a significant part of energy consumption. According to a report by the International Energy Agency, this sector consumes around 30% of the world's energy and generates 26% of energy-related emissions, which places it at the center of efficiency and decarbonization strategies.
Within that consumption, HVAC systems represent one of the components with the greatest impact. Research by the U.S. Department of Energy indicates that these systems account for about 35% of total energy consumption in buildings, the largest proportion attributable to an end use.
"When the long-term results are analyzed, it is clear that energy savings in buildings require efficient air conditioning," explains Enrique Tello, general manager of Trane Mexico. "It is not just about renewing equipment, but about integrating HVAC systems that are conceived from the design, are correctly managed in the operation and are continuously monitored to respond to the real use of the spaces."
Efficient buildings, more sustainable cities
In addition to its direct impact on operating costs, the energy performance of buildings also has a growing weight in the climate and urban agenda. In the development of smart cities, energy efficiency in HVAC systems has become a key criterion for creating more sustainable and livable spaces.
In Mexico, the challenge is particularly relevant. The National Commission for the Efficient Use of Energy warns that, without immediate action, emissions from commercial and residential buildings could multiply up to 6.7 times by 2050.
Against this backdrop, the modernization of HVAC systems, thermal electrification, and the adoption of data-driven energy management platforms are emerging as some of the most direct measures to reduce the operational carbon footprint of cities.
Technological advances have made it possible to develop air conditioning solutions capable of reducing energy consumption while improving comfort and operating conditions in buildings. Key benefits of modern HVAC systems include:
- Significant reduction in energy consumption, thanks to high-performance equipment and intelligent controls that adjust the operation to the real conditions of the building.
- Data-driven energy management, using digital platforms and sensors that allow performance to be monitored in real time and inefficiencies to be identified.
- Automatic adaptation to the use of the building, with systems that adjust the air conditioning according to occupancy, schedules and weather conditions.
- Improvement of indoor air quality, through integrated ventilation, filtration and humidity control solutions.
- Promotion of operational decarbonisation, through thermal electrification and the replacement of fossil fuel-based equipment.
- Greater operational stability and asset life, by reducing unforeseen failures and optimizing maintenance.
In the residential and smaller-scale projects, ductless HVAC systems have gained relevance as an efficient and flexible alternative. By eliminating the energy losses associated with traditional ductwork, they allow air to be directed directly into conditioned spaces, improving thermal control and reducing energy consumption.
Air conditioning as a lever for sustainability
In both commercial buildings and homes, the challenge is similar: maintaining comfortable and healthy spaces while controlling energy consumption. In this context, efficient air conditioning has established itself as one of the main tools to move towards more sustainable operating models.
"Air conditioning is one of the points where the interests of people, organizations and the planet intersect. Investing in efficient HVAC systems that contribute to energy savings in buildings is a concrete way to ensure more viable, comfortable and sustainable infrastructures in the long term," concludes Enrique Tello.
