The core advantages of ERV (Energy Recovery Ventilation) systems are recovering air energy, controlling humidity, and improving air quality in enclosed spaces. 

Adapted to Connecticut's climate and building characteristics, this system is suitable for various types of buildings in specific areas, as well as in cities within the state with ERV service support. Specifically:

1. Suitable Areas Based on Building Scenario

1. Newly Built Enclosed Residential Areas Statewide: Connecticut experiences cold winters and hot, humid summers. 

Newly built homes often employ tight sealing and insulation designs for energy efficiency, resulting in poor indoor air circulation. In new communities in cities like Farmington and Shelton, 

installing ERV systems can recover heat or cold energy during ventilation, preventing a surge in energy consumption due to window opening in winter and summer, while also solving problems 

such as odors and mold growth in enclosed spaces.

2. Industrial and Commercial Areas: Office buildings, laboratories, hospitals, and other facilities in cities throughout the state have high requirements for air quality and energy consumption control. 

For example, in factories and office parks in Hartford (the state capital, with a high concentration of industry and commerce) and Waterbury (a manufacturing hub), as well as university research laboratories

in New Haven, ERVs can continuously supply fresh air to protect the health of personnel while reducing the energy consumption of air conditioning and heating systems, 

meeting the long-term operational needs of commercial and research facilities.

3. Humid and Rainy Coastal and Lakeside Areas: Southern Connecticut, bordering the Atlantic Ocean, includes coastal cities such as Stamford and Norwalk, where summer humidity is extremely high, 

leading to problems like damp walls and moldy furniture indoors. ERVs can pre-dehumidify outdoor air during introduction, significantly improving comfort when used with air conditioning; in winter, 

they can also recover indoor moisture, preventing excessive dryness, making them an ideal ventilation choice for residences and businesses in these areas.

2. Key Cities with Well-Developed ERV Services: These cities have professional ERV installation and maintenance service providers, ensuring reliable installation and operation, and reducing subsequent 

maintenance costs. For example, Sheldon has Budderfly, which provides ERV-related energy optimization services; Stamford and Norwalk have companies like P&M Mechanical that undertake 

ERV installation and replacement services; and Danbury and Norwich also have several HVAC companies that can provide ventilation duct installation services for ERV systems, making it convenient for 

local users to install and maintain the equipment.
