Efficient Office Ventilation for Better Air Quality

Offices are built for people and the quality of ventilation in the indoor environment will affect their health, comfort and productivity.

Offices are found in a wide range of buildings—from business premises and schools to factories and retail spaces—making them a central part of most commercial environments. That’s why ensuring clean, comfortable air is essential for protecting health and supporting well-being in the workplace.

FläktGroup delivers intelligent HVAC solutions that not only reduce energy consumption and simplify installation, but also ensure full compliance with modern standards. Our systems are designed to maintain healthy air quality, regulate temperature and humidity, and remove pollutants and CO₂—creating a comfortable, productive environment where people thrive.

The Office Ventilation Challenge

Maintaining a healthy and productive office environment requires more than just heating and cooling—it demands precise control over five critical indoor air parameters.

Temperature must be consistent and comfortable to support focus and well-being.
Humidity levels need to be balanced to prevent dryness or dampness that can affect health and equipment.
Air velocity plays a subtle but vital role in comfort, as drafts or stagnant air can lead to discomfort or reduced air circulation.
Noise from HVAC systems can be a major distraction, making acoustic performance a key consideration in open-plan offices.
Finally, the supply of fresh air, free from odours and pollutants, is essential for cognitive function and overall health.

Challenge 1: Conference rooms

A conference room presents a unique challenge, with long periods of little or no occupancy versus times when full with bodies and electrical equipment. Managing the temperatures and fresh air in these rooms requires sensors and variable air flow to match the undulating occupancy levels.

Delivering high comfort levels by controlling temperature, and matching ventilation to highly variable occupancy levels whilst maxing on energy saving.

Solution: All air VAV system

When ventilation allocations are high and heat loads are below 100w/m2 room temperature can be effectively controlled with air as the coolant. Using EMSS damper responding to room thermostat and CO2 sensor, air flow can be varied for temperature control and fresh air regulation matching occupancy levels.

Thus simply matching ventilation to demand saves energy and when connected up to eQ Prime with ReCooler HP, further savings can be achieved from year round exceptional efficiency of the SEMCO energy recovery wheel and heat pump combination.

The eQ Air Handling Unit with ReCooler eliminates the need for rooftop condensers and pipework. Combined with the Veloduct system, it offers the simplest installation and significant on-site time savings

Solution: Air-water system with VAV Chilled Beams

For high heat loads and varying occupancy, chilled beam systems offer effective temperature control using water for up to 75% of the cooling load.

The WEGA II chilled beam combines efficient cooling with VAV functionality, adjusting ventilation to occupancy via the STRA-24 controller, proximity sensor, and CO₂ sensor. The demand control ventilation of WEGA II not only improves energy savings but also prevents discomfort from over-cooling at low occupancy levels.

Designed to run dry, chilled beams paired with the eQ Master and twin wheel system achieve highly efficient dehumidification, significantly reducing chiller and boiler size for lower life cycle costs.

Challenge 2: Open plan offices

Open plan offices must accommodate the needs of many occupants. Solutions from FläktGroup factor in the challenges of these spaces to ensure that comfort is maintained with variable air temperature to meet the demands of office employees.

Air Temperature challenge: Open plan offices must accommodate the needs of the many without affecting the comfort and productivity of any individuals. A particular challenge of these spaces is to ensure that environment is the correct temperature in spite of changing conditions, such as light entering at the windows or potential draughts.

Open plan offices have highly fluctuating occupancy levels and are seldom at full capacity. The ventilation on these open spaces needs to be variable in order to minimise cost and optimise efficiency.

Number of persons: 4-20

Solution: Air-Water System with Chilled Beams

Chilled beams provide ventilation, cooling/or heating. Working on the principle of induction to drive fresh air across heat exchanger coils, are the most efficient form of cooling with high comfort levels.

With cooling load distributed approximately 25%-75% between air and water, the highest proportion of the load is carried by water with 4 times higher cooling capacity than water, accounting for the highly efficient system.

Occupancy levels are rarely at 100% hence over cooling is the common complaint with CAV chilled beams systems operating on proximity sensing.

Ventilation levels in open plan office areas need to be turned down to match occupancy levels. VAV chilled beams with simple CO2 sensing would provide the required demand control at highest comfort levels.

Challenge 3: Cellular Offices

Room size and occupancy levels affect the temperature of an office room. A solution needs to be versatile and provide flexibility for indoor comfort throughout the day.

Air Temperature challenge: Offices are built for people, and the quality of ventilation in the indoor environment will affect their health, comfort, and productivity.

Occupancy levels in cellular offices frequently vary from overcapacity to vacant. Ventilation has to be managed to minimise cost and optimise efficiency.
