The Impact of Architectural Design and Proper Placement on the Energy Consumption of Air Conditioners

How Building Architecture and the Placement of Green Air Conditioners Affect Energy Efficiency and HVAC Performance

Practical guidelines, numerical examples, and model recommendations for optimal selection

Architectural design is not limited to aesthetics or building façades; it plays a fundamental role in energy consumption and the performance of heating and cooling systems. Among these systems, the air conditioner stands out as one of the most critical components. The correct selection and precise placement of an air conditioner can create a significant difference in cooling quality, thermal comfort, and energy costs.
In fact, architecture and air conditioning placement share a direct and reciprocal relationship: intelligent and well-planned architectural design allows the air conditioner to operate at its highest efficiency, while precise unit positioning enhances the overall energy performance of the building. This article explores the influence of architectural design on the energy efficiency of air conditioners, focusing on unit placement and the role of interior design.

Placement of Indoor and Outdoor Units

One of the key considerations for optimal energy use is the positioning of indoor and outdoor units.

Indoor Unit:

The indoor unit is responsible for distributing conditioned air within the room. Improper placement can increase energy consumption and reduce overall efficiency. When installed in a location with natural airflow, at an appropriate height, and free from obstructions, the indoor unit can deliver more uniform cooling or heating. Poor positioning creates dead zones, reduces system performance, and forces the compressor to operate for longer periods.

Key Guidelines:

Installation Height: Depends on the type of indoor unit (typically between 2.5 and 3 meters above floor level).

Airflow Path: Avoid placing the unit near furniture or curtains, as blocked airflow increases energy use.

Distance from Heat Sources: Keep the unit away from kitchens, bathrooms, and heat-generating appliances (heaters, radiators, etc.), which place extra load on the compressor.

Practical Tip: In a 20 m² room with a ceiling height of 2.7 m, the best performance is achieved when the indoor unit is installed at 2.2 m height and 30 cm away from the wall.

Outdoor Unit:

The outdoor unit houses the compressor and handles heat exchange with the external environment. Its placement directly affects energy consumption and system longevity. If exposed to direct sunlight or confined in an enclosed space, the unit experiences higher pressure and energy use. Installing theoutdoor unit in a semi-shaded area with adequate airflow and standard wall clearance significantly improves performance.

Key Guidelines:

Shade and Ventilation: Position in a shaded, well-ventilated area to lower compressor temperature and energy demand.
Clearance from Walls/Obstacles: Maintain at least 20–30 cm clearance from walls for optimal heat dissipation.
Service Accessibility: Smart placement reduces maintenance costs and extends system lifespan.

The Role of Interior Architecture in Energy Efficiency

Interior architecture plays a vital role in determining the performance of an air conditioning system. Smart spatial design facilitates smooth airflow and prevents thermal stratification across different zones. In open-plan areas with fewer obstacles, the air conditioner can maintain uniform temperatures without prolonged operation.
Material selection in interior design also has a direct impact on energy efficiency. Flooring, wall coverings, curtains, and furniture all influence energy retention or loss. Using thermally and acoustically insulated materials reduces the cooling load. Likewise, the placement of windows, type of glazing, and even wall colors can affect the overall cooling or heating demand.
In other words, interior architecture is not limited to aesthetics or functionality it provides the framework for an air conditioner to operate efficiently with minimal energy use. This factor is particularly crucial in commercial and office environments, where a well-designed interior not only enhances system performance but also ensures sustained thermal comfort for occupants.
