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.
