Decarbonize Building Operations With an Optimized HVAC System
Utilize simulation and virtual twin technology to create optimal HVAC systems and reduce building emissions from end to end.
Understanding HVAC Systems for Energy Optimization and Decarbonization
HVAC (Heating, Ventilation, and Air Conditioning) systems are key to reducing energy consumption and carbon emissions in buildings. By optimizing heating, cooling, and ventilation processes, modern HVAC systems can significantly improve energy efficiency. Utilizing advanced technologies like simulation and virtual twin models, these systems help identify inefficiencies, lower operational costs, and contribute to the decarbonization of building operations, making them crucial for sustainability efforts.
Fight Global Warming With Indoor Climate
Heating, ventilation and air conditioning (HVAC) in buildings is one of the largest contributors to global carbon emissions. HVAC systems are currently responsible for 20%1 of building electricity consumption worldwide and 10%2 of all global electricity consumption.
As such, HVAC performance cannot be an afterthought but must be integrated into every stage of HVAC system design to lower its end-to-end carbon footprint. And HVAC optimization is possible by utilizing virtual twin technology for HVAC simulation.

Government Regulations and Standards for HVAC Systems
Compliance with Energy and Building Codes
HVAC systems must meet local building codes and energy efficiency standards to ensure optimal performance and environmental responsibility. Key standards include ASHRAE 90.1 in the U.S. and the Energy Performance of Buildings Directive (EPBD) in the EU.
Sustainability Certifications
HVAC systems are often designed to meet sustainability certifications like LEED and BREEAM, which set benchmarks for energy efficiency and carbon reduction in building operations.
Supporting Decarbonization Goals
By adhering to these regulations, HVAC systems can significantly reduce energy consumption, lower carbon emissions, and contribute to global sustainability efforts.
Balance Energy Efficiency, Indoor Air Quality and Comfort
A holistic approach is needed to overcome the challenges of building and sustaining green buildings. While demand for energy efficiency has become more stringent, indoor air quality and comfort cannot be compromised. Instead, these three competing factors need to be optimally balanced.
To deliver HVAC systems with a lower carbon footprint while preserving comfort and air quality, manufacturers can leverage 3D modeling and simulation technologies for insights into HVAC performance. For example, simulation can be used to predict the emission, propagation and deposition of particles across the built environment versus the impact they have on the safety of building occupants.
Backed by virtual twin technology, simulation can accelerate cost-effective, sustainable HVAC innovation. For instance, simulation of a building’s virtual twin enables engineers to quickly spot and rectify causes of inefficient heating including:
Weather effects
Existing or potential sources of heat loss
Inaccessible locations for the HVAC system
Advancements in Adaptive Building Design
“By leveraging newer technologies and adaptive building designs, recent studies estimate that cooling and heating energy consumption intensity could decrease by 23%3 and 75%4 respectively.”
With simulation, HVAC components and systems can be designed and optimized much earlier in tandem with the rest of the building without compromising safety and security. Engineers and architects can improve the system’s integration in building operations from the onset to:
Reduce operating costs
Maximize occupant comfort
Ensure indoor air quality compliance
Benefits of Optimized HVAC Systems
Energy Efficiency
Optimized HVAC systems reduce energy consumption by using advanced technology like sensors and controls to minimize waste. This leads to lower energy bills and helps buildings meet sustainability goals.
Improved Air Quality
An optimized HVAC system improves indoor air quality by efficiently filtering pollutants like dust and allergens. This creates a healthier environment for building occupants.
Lower Carbon Emissions
By consuming less energy, optimized HVAC systems directly reduce carbon emissions, contributing to lower environmental impact and helping meet sustainability regulations.
Cost Savings
Optimized HVAC systems lower utility bills and reduce maintenance costs over time, providing significant long-term savings despite any initial investment.
Enhanced System Longevity
Efficient operation of optimized HVAC systems reduces wear and tear, extending the lifespan of components and minimizing the need for replacements.
One for All Climate System Platform
As a collaborative hub, the 3DEXPERIENCE® platform brings together systems engineering, modeling, simulation and project management solutions to streamline all HVAC system processes and support innovative collaboration on a single integrated cloud-based platform.
"We can use the 3DEXPERIENCE platform to educate and communicate how the building performs," shared Charles Luzzato, SIMULIA Global Industrial Equipment Industry Process Expert at Dassault Systèmes.
Through the platform, the entire HVAC ecosystem can utilize simulation for year-round performance verification to ensure that HVAC systems operate efficiently, even in the hottest summer and coldest winter.
Backed by data-driven insights from multiscale simulations on the 3DEXPERIENCE platform, the carbon footprint of HVAC systems can be reduced from cradle to cradle. And this will go a long way to cutting carbon emissions from the built environment by 2040 to meet the 1.5° climate targets.

FAQ About Heating, Ventilation, and Air Conditioning System & Technology
HVAC, which stands for Heating, Ventilation, and Air Conditioning, refers to a specialized mechanical system employed for regulating temperature, humidity, and air purity within enclosed spaces. This encompasses a wide spectrum of HVAC-related aspects, including:
- split systems,
- cooling systems,
- heat pumps,
- control systems,
- and energy-efficient options.
An HVAC system, often installed and maintained by skilled HVAC technicians, plays a pivotal role in ensuring the comfort and well-being of occupants across various settings like:
- residential homes,
- commercial establishments,
- educational institutions,
- and healthcare facilities.
Key HVAC components, including fans, heaters, air conditioners, and ductwork, collaboratively function to circulate air efficiently and maintain desired temperature zones.
HVAC systems, crucial for maintaining a comfortable and secure indoor atmosphere, come in four primary varieties, with distinct benefits tailored to home size and regional climate conditions. These main types are:
-
Split Systems: These HVAC systems divide heating and cooling components, offering flexibility in managing temperature zones efficiently.
-
Packaged Systems: Packaged systems integrate heating and cooling units into a single unit, making them suitable for smaller homes or spaces with limited installation space.
-
Ductless Mini-Splits: Ductless mini-split systems provide a versatile solution, ideal for zones within homes that require individualized temperature control.
-
Geothermal Systems: Geothermal systems harness the earth's consistent temperature to offer an energy-efficient HVAC option, particularly advantageous in regions with varying climates.
HVAC, which stands for Heating, Ventilation, and Air Conditioning, represents a comprehensive system employed for regulating the climate within a designated space. It encompasses a range of related elements, including:
- split systems,
- cooling systems,
- heat pumps,
- control systems,
- and energy-efficient options.
It's important to note that while air conditioning is a component of HVAC, the two are not synonymous.
HVAC systems reduce a building’s carbon footprint by optimizing energy use through efficient heating, cooling, and ventilation processes. By using less energy and incorporating renewable energy sources (solar and geothermal), they minimize greenhouse gas emissions, contributing to decarbonization efforts.
