Requirements for the ventilation of business centres

There are different types of business centres, which are ranked from the most comfortable to the most modest ones, according to the generally accepted classification (A, B, C, D).

Class A business centres are typically newly built edifices with new utility lines, including water, heat and power supply systems, lighting, and building’s BMS. Their climate control and ventilation systems are, as a rule, developed at an early design stage. Class B administrative space is provided both in new and historical refurbished buildings, and has a good quality engineering infrastructure.

Class C and D business centres are frequently located in old administrative buildings and sometimes in premises that require major repairs such as former housing stock. Large-scale repairs and replacement of utility lines help make such premises more convenient for work and attractive for tenants, while the class of office centre is upgraded.

Regardless of whether the business centre is a greenfield or a brownfield project, it needs an elaborate ventilation and air conditioning system that takes into account the specifics of office space.

The use of a large number of lighting fixtures and office equipment in business centres leads to high heat surpluses. At the same time, lofts and open-plan offices feature large areas and high ceilings. The temperature is such spaces is unevenly distributed since warm air rises up, so it is important to ensure a uniform air supply using a ventilation system.

The personnel work in the offices for most of the day, so it is essential to provide for an uninterrupted flow of fresh air and removal of extract air. In enclosed spaces, where people stay during the day, the CO₂ content rapidly rises. Lack of oxygen and excess of CO₂ lead to high fatigue of people and reduce their productivity. At the same time, office centres have different function areas and various types of office space that require individual ventilation and air conditioning solutions. While there are people permanently staying in the main workspace, the conference and meeting rooms are only used occasionally.

Creating a comfortable indoor climate in business centres requires a comprehensive system that will provide for airing, heating and cooling, draft-free removal of excess heat, and will not occupy to much usable area and ensure individual operating modes for different rooms.

Solution to provide for a proper indoor environment in business centres

Swegon AB offers end-to-end integrated technical solutions for business centre ventilation based on the use of various types of equipment. The Swegon Office Solution Air system provides solutions for ventilation, cooling and heating, and the Swegon Office Solution Water system is responsible for climate control using hot and cold water. Both solutions are based on the use of Swegon’s GOLD air handling unit, with a capacity of up to 7.8 cub m/s. The unit is fitted with Wing fans with a controlled rotational speed and a high performance Reconomic rotary heat exchanger.

Advantages of Swegon Office Solutions

Comfortable indoor climate

The use of diffusers and cooling beams with mild air dissipation helps ensure an efficient air exchange without draughts and with a uniform supply of fresh air to all the workplaces.

Automatic controls and communication

The automatic controls kit with a sensor module built into the diffuser monitors temperature and climate parameters, and changes them on demand; an option is provided to optimize and record the log file. Control can be conducted via the web interface, with an option of integration with the business centre’s BMS.

Energy efficiency

Demand-controlled ventilation of business centres, which takes into account the number of people in the room at any given moment, helps considerably reduce the operating costs.

Demand-controlled ventilation

Operating modes are adjusted using the data transmitted by sensors that detect human presence in the offices, as well as the air temperature and CO₂ concentration, and take into account the on/off switching of electrical appliances.
