Based on Saudi Arabia's climate characteristics and building requirements, the following areas are particularly suitable for the application of ERV (Energy Recovery Ventilation) systems 

to achieve efficient energy saving and improve indoor air quality:

1. Industrial and energy facility concentration areas

Yanbu Industrial Zone: The temperature in energy bases such as refineries can reach 50°C in summer, and the working environment needs to strictly control the concentration of harmful gases; 

the ERV system can recover energy while ensuring ventilation volume, reduce the air conditioning load in high temperature environments, and purify fresh air through chemical filters.

Petrochemical explosion-proof control room: Such facilities require constant temperature and humidity and maintain a positive pressure environment. ERV can accurately control the

 fresh air volume and filter harmful gases such as hydrogen sulfide, which meets the requirements of the "Petrochemical Control Room Explosion-Proof Design Code".

2. Cluster of large new infrastructure projects

NEOM Future City (THE LINE, OXAGON): Future cities built in the desert need to deal with 50℃ high temperatures and dust. The Chinese team has deployed high-density 

5G base stations and clean energy systems in the area⁶; ERV can cooperate with intelligent building management to achieve low-energy ventilation, especially suitable for enclosed super buildings

 (such as THE LINE's vertical urban structure).

Trojena Winter Olympics venues: Snow mountain facilities at an altitude of 1500-2600 meters need to balance the temperature difference between indoor and outdoor. The energy recovery 

function of ERV can greatly reduce heating energy consumption, which is in line with its 100% clean energy power supply goal.

3. High-density commercial and urban core areas

Riyadh Metropolitan Area: As the largest HVAC demand market in Saudi Arabia (accounting for 51% of the Gulf region), the local $732 billion worth of projects under construction

 (including commercial complexes and hotels) urgently need to reduce the energy consumption of air conditioning systems¹; ERV can significantly reduce cooling losses in commercial buildings.

Jeddah Port Expansion Area: The high temperature and high humidity of the Red Sea coastal environment increase the burden of air conditioning. The humidity regulation ability of 

ERV can optimize the indoor environment.

4. Key factors of technical adaptability

Climate adaptability: Saudi Arabia is full of deserts. The ERV system needs to be equipped with efficient sand filter (such as wind and sand blocking net technology¹¹) and deal with equipment

 wear caused by sandstorms.

Policy orientation: "Vision 2030" promotes sustainable building standards. The energy-saving characteristics of ERV (recovering 70-90% of exhaust energy) are in line with the goal of green transformation.
