Why and How Energy Efficiency?

Fans account for up to 25% of a building's energy consumption.

Their energy efficiency is critical.

Buildings consume a lot of electricity

Buildings represent 40% of the total energy consumed in Europe
They generate 36% of energy related greenhouse gas emissions
85% of buildings in EU were built before year 2000
75% of all buildings are not energy efficient
85-95% of EU buildings are expected to still be standing in 2050

And EU legislation is becoming strict

Four EU Directves will drive up energy prices

EU Emissions Trading System (ETS) 2.0
European Climate Law
EU Energy Efficiency Directive
EU Energy Performance of Buildings Directive

Emissions trading system 2.0

Will become fully operational in 2027
Will address CO2 emissions from fuel combustion in buildings
Is a cap and trade system with allowances decreasing every year
The consequence is higher energy prices for buildings

The EU Commission wants ETS2.0 to incentivize building renovation

"The carbon price set by the ETS2 will provide a market incentive for investments in building renovations and low-emissions mobility"

The Energy Efficiency Directive complements ETS2.0

Became operational in October 2023 in the EU
It's aim is to reduce energy consumption in EU by at least 11.7% by 2030
Makes regular energy audits mandatory for large companies
Energy efficiency inspections of HVAC installations of over 70 kW become mandatory, by law

Energy efficiency in European buildings is of paramount importance. Strict legislation on CO2 emissions reduction and increasingly higher electricity prices will force European businesses to focus on energy efficiency initiatives.

HVAC is 50% of a building's energy needs

On average, HVAC systems account for about 50% of a building's energy needs. This may be as high as 60% depending on the type of building.

ventilation fans are a major energy consumer

Fans account for roughly 40% of the total HVAC energy consumption. As such, fans alone may account for up to 25% of a building's energy consumption. As such, their energy efficiency is critical.
