DEMAND-CONTROLLED VENTILATION – FOR SUSTAINABLE BUILDINGS

At Lindinvent, everything revolves around optimizing energy use. With demand-controlled ventilation, airflow, cooling, and heating are adjusted based on actual occupancy, creating an energy-efficient and healthy indoor climate. Through our LINDINSPECT® web interface, property owners can monitor, control, and optimize indoor conditions in real time, saving both energy and costs while enhancing the overall indoor environment.

Ventilation Based on Demand – The Obvious Choice

Studies show that occupancy rates in buildings rarely exceed 60% and often average around 35%. Yet, many buildings are ventilated as if they were fully occupied 24/7. Demand-controlled ventilation ensures that airflow is adjusted based on actual occupancy, significantly reducing unnecessary energy consumption.

For example, buildings do not need to consume 143.5 kWh per m² annually, as reported by the Swedish Energy Agency’s STIL studies. With intelligent climate control, energy use can be reduced to below 53 kWh per m² annually, even in older buildings without additional insulation.

Optimized Cooling and Heating Needs

Lindinvent’s system efficiently manages low supply air temperatures, enabling high-performance heat recovery. In many cases, heating demands can be met without additional heating installations. Similarly, excessive airflow is avoided during higher outdoor temperatures, as smart controls ensure cooling is delivered in the most energy-efficient way.

Profitability Beyond Energy Savings

When investing in demand-controlled ventilation and climate control, it's essential to consider more than just initial costs and annual energy savings. The benefits extend far beyond, enhancing property value and improving workplace environments:

• Lower operating costs – Modern technology enables remote monitoring and optimization, reducing maintenance time and service expenses.
• Reduced energy consumption – Smart climate control minimizes unnecessary energy use and lowers environmental impact.
• Better working environment – New ventilation solutions operate quieter, reducing stress and absenteeism.
• Higher rental value – Improved comfort justifies premium pricing.
• Increased productivity – A ±4°C temperature deviation can reduce productivity by 5%, while fresh air can boost it by 3%.
