What are MEP installations?
MEP stands for Mechanical, Electrical & Plumbing: the set of installations that serve a building (HVAC, electricity, water, gas, fire protection and telecommunications). Each one has its own regulation and, depending on its size or power, requires a technical project or a technical report, in addition to compliance with the Technical Building Code (CTE).
Installations and their regulations
These are the main installations of a building and the regulations governing each one:
| Installation | Main regulation |
|---|---|
| HVAC, ventilation and DHW | RITE |
| Low-voltage electrical installation | REBT |
| Fire protection | CTE DB-SI + RIPCI |
| Plumbing and sanitation | CTE DB-HS (healthiness) |
| Gas installations | Gaseous fuels regulation (RD 919/2006) |
| Telecommunications (ICT) | ICT regulation (RD 346/2011) |
| Energy efficiency | CTE DB-HE |
HVAC and DHW (RITE)
The Regulation on Thermal Installations in Buildings requires a technical project for installations with a nominal thermal power greater than 70 kW, and a technical report for those with a power greater than or equal to 5 kW and less than or equal to 70 kW (below 5 kW no technical documentation is required).
Aerothermal energy and VRF systems
Aerothermal energy (an air-to-water heat pump) generates heating, cooling and domestic hot water from renewable energy in the air, with reduced electricity consumption. In the Balearic Islands it attracts great interest due to the Mediterranean climate: mild winters that maintain high performance and strong cooling demand in summer. In buildings with several rooms or uses, it is usually combined with VRF systems (variable refrigerant flow), which adjust the power to the demand of each zone with great efficiency.
Electricity (REBT)
The Low-Voltage Electrotechnical Regulation (REBT) determines, in its instruction ITC-BT-04, which installations need a project and which a technical design report, depending on the power and the use. Premises open to the public, for example, always require an electrical project.
Fire protection
The design is governed by the CTE DB-SI (safety in case of fire) and the installation of the equipment (detection, extinguishing, emergency lighting) by the Regulation on Fire Protection Installations (RIPCI).
What do we do?
We coordinate and legalise all the installations of your building or premises through a single technical point of contact:
Frequently asked questions
What are the MEP installations of a building?
They are the mechanical, electrical and plumbing installations: HVAC, electricity, water, gas, fire protection and telecommunications. Each one is governed by its own regulation and by the Technical Building Code (CTE).
When does an HVAC installation require a project?
The RITE requires a technical project for thermal installations with a power greater than 70 kW, and a technical report for those with a power greater than or equal to 5 kW and less than or equal to 70 kW (below 5 kW no technical documentation is required).
