ERV (Energy Recovery Ventilation) systems are suitable for locations requiring high airtightness, strict temperature and humidity control, and excellent
air quality, while also needing to reduce energy consumption. Considering the temperate continental climate of Iowa and Kansas (large temperature
differences, humid summers, and cold winters) and the characteristics of local buildings and functions, the following are suitable areas and specific
locations for installing this system:
### Iowa
Iowa experiences warm, humid summers and long, cold winters, with varying rainfall and temperatures across different regions. ERV systems can recover
energy in both summer and winter to save energy while also regulating humidity. Suitable installation locations are concentrated in commercial buildings and
densely populated residential areas in major cities, specifically including:
1. **Des Moines**: As the state capital and core city, its historic Market One building was the state's first net-zero energy commercial building, and an
ERV system from AUDES was installed during its renovation. Renovated older commercial buildings, as well as newly built office buildings and
shopping malls, where high airtightness and a balance between ventilation and energy control are required, are the core application scenarios for ERV
systems. In addition, high-end residences and multi-family apartments in cities are also suitable for installation.
2. **Ames:** Local HVAC service providers explicitly offer ERV-related residential ventilation system services. Newly built energy-efficient homes and
older houses that have undergone energy-saving retrofits often suffer from insufficient natural ventilation due to improved sealing. Installing ERVs can
replace indoor air while simultaneously reducing energy consumption in conjunction with heating and cooling systems, meeting local residents' needs
for both indoor air quality and energy efficiency.
3. **Wenton and Other Cities:** HVAC companies in Vinton offer ERV installation services for local residences as a key solution for improving indoor air
quality. In addition, cities with high concentrations of universities or thriving industries, such as Cedar Rapids and Iowa City, with their schools,
laboratories, and small manufacturing plants requiring high levels of air circulation and stable temperature and humidity, are also well-suited to
ERV systems.
4. **Northwest Region of the State:** This region experiences low rainfall and extremely cold winters (minimum temperatures can reach -20°C to -25°C).
Installing ERVs in local residences and small commercial buildings can recover indoor heat to reduce winter heating energy consumption and introduce
treated fresh air, preventing air pollution caused by prolonged closure.
### Kansas
The eastern part of Kansas experiences high rainfall and a wetter summer, while the western part is arid and prone to dust storms. The entire state enjoys
many sunny days and significant temperature variations. ERVs can specifically address ventilation and energy consumption issues in different areas.
Suitable areas and locations include:
1. **Kansas City Metropolitan Area**: Covering the urban area on the Kansas side and surrounding Johnson County, many local HVAC companies
specialize in services such as creep space ventilation. ERVs can be used in various types of buildings in this area, such as office buildings and hotels in
commercial areas, high-density apartments in residential areas, and energy-efficient single-family homes in the suburbs. Supermarkets, restaurants,
and other commercial establishments in this area require continuous ventilation and temperature and humidity control; installing ERVs can reduce the
load on air conditioning and heating systems.
2. **Wichito**: As a major industrial and commercial center in the state, Wichita has HVAC equipment distributors such as Hajika, making it easy to obtain
ERV-related equipment and services. Manufacturing plants, warehouses, large retail stores, and public buildings such as hospitals and schools in the city
have significant needs for ventilation and energy consumption control, making them suitable for large-scale installation of ERV systems.
3. **Suburban Cities like Orasi and Overland Park:** These cities are primarily residential and small commercial establishments, where local HVAC service
providers frequently undertake residential ventilation retrofit projects. Installing ERVs in newly built villas, townhouses, and community-affiliated small
shops and gyms in these areas can improve indoor air quality and adapt to the local climate's large temperature variations, reducing energy costs in
winter and summer.
4. **Arid Western Regions of the State:** Western cities like Garden City experience low rainfall and frequent dust storms. Installing ERVs in local
residences, schools, and small office buildings can filter dust when introducing fresh outdoor air, while simultaneously recovering indoor energy,
avoiding drastic fluctuations in indoor temperature and humidity caused by frequent ventilation, and balancing ventilation, dust control, and
energy-saving needs.
