There are 2 levels of commercial EPC, which one your building requires depends on the following:
Level 3
This refers to buildings with typical features in terms of construction materials, layout, and design. Think of small shops, restaurants, or offices. Total heating system capacity should be less than 100kW, this generally means smaller boilers or individual heating units. If the building has air conditioning, its total cooling capacity should be under 12kW. This typically covers single units or small split systems.
Level 4
These buildings have features that are not typical of standard commercial structures. This could include unusual shapes, unique construction materials, or specialised internal layouts. Level 4 buildings often have more sophisticated heating, ventilation, and air conditioning systems. This might involve Heating systems greater than 100kW, cooling systems greater than 12kW, multiple zones with different temperature controls and air handling units.
Commercial EPC
tm44 inspection
There are 2 levels of TM44 inspections, which one you require depends on the following:
Level 3
Typically applies to buildings with self-contained units often found in individual rooms or smaller spaces, examples include split systems, multi-split systems, and window units, smaller VRF/VRV systems without complex controls or central management, the system doesn't have large chillers, extensive ductwork, or complicated control systems.
Level 4
These often involve chillers that produce chilled water distributed throughout the building to cool the air, larger VRF/VRV systems with advanced controls, multiple zones, and potentially integrated building management systems and air handling units. The AC system might be interconnected with other building systems like ventilation and heating, requiring a more integrated assessment.
asset registers
An asset register provides a complete list of all assets, including those that consume energy, such as HVAC systems, lighting, and production equipment. This allows for a thorough understanding of energy consumption patterns within a building or organisation. By tracking the age and condition of assets, the register helps identify outdated or inefficient equipment that may be consuming excessive energy. This information supports informed decision-making about upgrades or replacements with more energy-efficient models. An asset register enables the scheduling of regular maintenance for energy-consuming equipment. Proper maintenance ensures that systems operate at peak efficiency, minimizing energy waste. For example, regular filter changes in HVAC systems or cleaning of lighting fixtures can significantly improve energy performance.
