Old belt-driven fans often use up to twice the electricity necessary and require frequent maintenance. Installing modern direct-driven chamber fans with EC motors can cut energy use by up to 50%. The benefits are lower operating costs, less maintenance and more stable operation.

Much of the heat in ventilation exhaust is lost if the recovery unit is outdated. Upgrading to high-efficiency rotary heat recovery with up to 80% efficiency can reduce heating demand considerably. The result is lower energy use, better indoor climate and longer lifetime for the ventilation system.

When control systems do not adapt to actual use, equipment often runs at full speed unnecessarily. With modern automation, ventilation can be regulated by time, temperature and air quality. The result is optimal comfort, lower energy bills and better insight into consumption.

In many buildings all rooms receive the same air regardless of usage. By introducing zone and demand control, air volumes are adapted to occupancy and needs in each area. The advantage is better air quality where people actually stay, while unnecessary energy use is eliminated.

Poorly balanced systems can make some rooms too hot while others are too cold. Proper commissioning and control of heating and cooling systems can improve both comfort and energy efficiency. This results in a stable indoor climate, lower energy use and less wear on equipment.

Over time, incorrect settings, clogged filters and missing recirculation control can cause the system to work harder than necessary. By optimising airflow, replacing filters and adjusting recirculation, both energy use and operating costs are reduced. This is often a quick win without major investment.

Older or wrongly sized heating systems can waste energy. Installing modern heat pumps tailored to the building reduces electricity use and operating costs. The benefit is stable heat year-round and a quick return on investment.

Uninsulated or poorly insulated pipes cause significant heat loss. Insulating heating and hot water pipes keeps heat where it is needed and reduces energy use.

When a heating system is not regulated according to actual demand, more energy is used than necessary. With smart heating control, heating can be adjusted by schedule, temperature and usage patterns. This results in better comfort, more consistent indoor temperatures and reduced energy costs.

Many buildings have outdated heating plants with high energy consumption and limited flexibility. A compact, factory-built NeoTemp energy center can be placed directly and connected to existing systems. The advantages are fast installation (plug-and-play), optimal operation and the possibility to combine multiple energy sources.

For buildings with high heating energy demand, biomass heating can be a climate-friendly alternative. By using renewable biofuels instead of fossil energy sources, both greenhouse gas emissions and operating costs are reduced. This provides a more sustainable heat supply without compromising performance or capacity.

Over time, incorrect settings, unbalanced systems and lack of maintenance can lead to unnecessarily high energy consumption. Through systematic optimization of heating systems — including commissioning, component replacement and adjustments — performance can be significantly improved. The benefits are lower energy use, more even heating and a longer lifetime for the system.

Old fluorescent and halogen fixtures use much energy. Upgrading to LED can reduce lighting consumption by up to 70%.

Motion and daylight sensors activate lighting only when needed and dim automatically in good daylight.

Smart charging with load balancing distributes power so the grid is used optimally and charging is safe and efficient.

Large machines or heating systems starting simultaneously cause costly peaks. Load management staggers starts to lower peak charges.

Many buildings have high electricity consumption at times when there is no activity. By analysing the usage pattern and adapting the operation to actual needs, consumption can be significantly reduced. The advantage is that unnecessary energy use is cut, without compromising comfort or function.

Roofs and facades can be an untapped source of energy. By installing solar panels, electricity is produced directly from the sun, which reduces the need for purchased energy. The advantage is lower electricity bills, the possibility of selling excess power and a clear contribution to green energy.

Water heating accounts for a large part of the energy consumption in many buildings. Solar collectors harness the sun's heat to produce hot tap water or contribute to heating. The result is reduced heating costs and less strain on other heat sources.

On sites with good wind conditions, small-scale wind turbines can be an effective supplement to the power supply. They can help reduce dependence on the grid and provide a stable supply of renewable energy. The benefits are increased energy security and lower purchasing costs over time.

Large amounts of surplus energy can be stored for later use to improve self-consumption and reduce power peaks.

Large amounts of heat can be stored in tanks or purpose-built systems for later use, resulting in more even energy consumption, lower costs and increased operational flexibility.

Many buildings lose large amounts of heat through walls, roofs and floors. By insulating them, heat loss can be significantly reduced, resulting in lower heating needs. The benefits are better indoor climate, reduced energy costs and increased building value.

Old windows often let in more heat than they let in light. By switching to modern windows with high insulation values, you keep the heat in and the cold out. This results in better comfort, lower energy consumption and reduced draught problems.

Improvements to a building's envelope – walls, roofs, windows and doors – determine how well it protects against weather and temperature changes. Enhancements to the envelope can lead to significant savings and longer lifespan for the building. The result is improved energy efficiency and increased resilience to wear and tear.

Even small air leaks can lead to significant heat loss and moisture problems. Airtightness testing identifies leak points so they can be sealed effectively. The benefits are reduced energy use, improved comfort and fewer building damages.

Without the right tools, it's hard to see where the building leaks heat. Thermography provides a visual map of heat leaks and cold bridges, making it easier to prioritise improvements. This enables targeted upgrades and better investment returns.

Modern energy management systems provide real-time data to discover deviations and tune operations.

AI predicts deviations and optimises operation continuously for higher efficiency and fewer interruptions.

Many buildings pay for both energy consumption and peak demand. With energy economics tools, consumption patterns are analysed to reduce both energy and peak charges, leading to more predictable costs and better capacity utilisation.

During periods of high consumption, it may be beneficial to shift some energy use to other times. Flexibility management allows adjustment of equipment operation based on power prices and grid load, reducing costs and contributing to a more stable power grid.

Consumption of water and handling of waste represent both an environmental and economic cost. With sensors and monitoring, leaks, overconsumption and unnecessary waste handling can be detected early. The benefits are lower operating costs, less waste and better resource utilisation.

The energy consumption in a building varies throughout the day, week and year. By mapping and analysing usage patterns, operations can be adapted to actual needs instead of fixed routines. The result is that unnecessary energy use is cut – without compromising comfort or functionality.
