Energy Efficiency

With the rapidly growing focus on the energy efficiency of building services and their contribution to the ‘carbon footprint’, Imofa UK is well equipped to help customers achieve their energy saving objectives on new and refurbishment projects by designing Air Handling Units, Ventilation Equipment and Air Handling Systems for Maximum Energy Efficiency.

Energy Performance of Buildings

Collectively accounting for more than 40% of Europe’s energy use, new and old building stock presents significant potential for cost effective energy saving and reduction of CO2 emissions. The EPBD (Energy Performance of Buildings Directive) now being implemented by all EU member states sets out minimum requirements on the energy performance of new and existing buildings.

UK Building Regulations Part L

Addressing this directive in the UK are Building Regulations Part L2 (fuel and energy conservation) for non-domestic new buildings (L2A) and refurbishment of buildings over 1000m² useful floor area (L2B).

Ventilation system – air quality

Whilst the reduction of air flow might reduce the energy consumed by ventilation fans and air handling units, reduced air change may have a detrimental effect on the internal environment and the target energy performance of a unit must take this in to account. This is addressed in the EPBD and UK building regulation Part F on air quality.

Imofa’s bespoke solutions

Imofa UK’s focus on bespoke air handling unit solutions enables it to readily address the balance between the aims of these directives on energy efficiency and air quality within the unique demands of each project. Units are designed for minimum airflow losses within dimensions allowed by allocated building space, and a variety of efficient heat recovery methods are employed. Units can also be designed to respond to demand control signals where the system designer employs this energy saving strategy to match ventilation rates to varying use and occupancy of the building.
