Energy recovery ventilation (ERV) systems have significant application value in specific climate areas with high temperature, dryness or high humidity in Egypt and in specific building types. 

The following is an analysis of key areas and scenarios suitable for deploying ERV systems:

I. Mediterranean and Red Sea coastal cities

Alexandria: As a typical Mediterranean climate city, the humidity in summer often exceeds 70% and it rains a lot in winter. The ERV system can efficiently recover humidity and energy in exhaust air, 

balance indoor humidity and reduce air conditioning dehumidification load, especially suitable for hotels, hospitals and high-end residences. ‌

Red Sea resorts (such as Hurghada and Sharm el-Sheikh): The high salt and high humidity environment along the coast accelerates equipment corrosion, and hotels need to maintain a constant comfort level. 

ERV can reduce the energy consumption of fresh air treatment and configure anti-corrosion coatings (such as C4M standards) to adapt to the marine climate. ‌

II. Large urban dense areas

Cairo and Giza:

The urban heat island effect is significant: dense buildings and automobile exhaust pollution aggravate indoor air quality problems. ERV reduces the intrusion of external pollutants and 

reduces air conditioning energy consumption by more than 30% through efficient filtration and energy recovery. ‌

New projects are preferred: such as the high-end office buildings and complexes in the New Administrative Capital (NAC), which comply with Egyptian green building standards 

(such as the national construction specification GB/T50430) and require energy-saving ventilation design. ‌

3. Desert Climate Industrial Zone

Suez Canal Economic Zone (SCZone):

Industrial plants and logistics centers: The high temperature and dry environment (up to 43°C during the day) leads to a surge in ventilation energy consumption. 

ERV can recycle waste heat from production equipment and use it to preheat winter fresh air or precool summer fresh air, significantly reducing the load on the HVAC system. ‌

Supporting new energy projects: such as the supporting facilities of the 500MW wind farm in the Gulf of Suez, ERV is suitable for harsh environments (anti-corrosion grade C4M) and 

supports the low-carbon operation of sustainable energy facilities. ‌

IV. Policy support and emerging project clusters

Government-led development of new areas:

New Administrative Capital (NAC): The plan requires building energy efficiency to be Class A, and ERV becomes a standard configuration for passive buildings. 

The centralized system can serve the entire building and reduce the equipment footprint. ‌

Technology Park (such as Beni Suef Science and Technology City): Although it is mainly based on information technology, high-energy-consuming buildings such as data centers need to

 control temperature and humidity. ERV synergistic heat pump technology can optimize PUE value. ‌

Implementation suggestions:

Climate adaptation design: In dry inland areas (such as Luxor), choose HRV with sensible heat recovery as the main method, and use full heat recovery ERV in coastal high-humidity areas.

Policy compliance: Egypt will strengthen building energy efficiency regulations from 2024 (refer to GB 42590-2023 extension standard), and new projects need to submit energy-saving assessments of

 ventilation systems. ‌

Localized services‌: It is recommended to cooperate with local Egyptian suppliers (such as Cairo HVAC-R exhibition partners) to solve operation and maintenance support and avoid cross-border equipment taxes 

(such as the analogous risk of 38.5% import tax on mobile phones). ‌

In summary, the applicability of ERV systems in Egypt is determined by geographical climate, building functions and policy orientation, and is mainly deployed in coastal cities, industrial belts and emerging urban 

core areas. At the same time, it is necessary to combine localized technology adaptation and regulatory compliance strategies.
