LEED® Certification is a method for the assessment of efficient buildings.

From an energy viewpoint and through objective design guidelines and quantifiable parameters, it enables you to measure, among other things, the efficient use of energy, water, the correct use of materials, and indoor environmental quality.

The final assessment is awarded by the Green Building Council of the USA which is a non-profit organisation that promotes the implementation of excellent practices in

Types of LEED®

  • New Constructions
    Designed for new commercial office construction and all buildings are eligible for this type of LEED®.
  • Existing Buildings
    Aimed at maximising operational efficiency and minimising a building’s environmental impact, it is applicable to both new and newly constructed buildings.
  • Homes
    Energy-efficient design and construction to transform homes into efficient homes that consume less water and natural resources, generate less waste, and are healthier.
  • Neighbourhood development
    Integrates the principles of smart growth, urban planning and efficient building.
  • Schools
    Applicable to education centres.


LEED® Credits

Aire Limpio technologies, both the SIPAP® Active Polarisation and the SFEG® Photocatalysis provide different LEED® credits such as:

Energy and Atmosphere

Prerequisite 1. Energy Efficiency. Best management practices: create a preventive management plan for air filters and a document with the schedule for planned changes.

Prerequisite 2. Energy efficiency minimum figures: use a calculation tool to gauge the impact on energy costs of the pressure loss in filters.

Credit 2.1. Planning of start-up in the existing building: carry out the analysis of the life cycle and the energy costs of the air filtration system. Provides 2 LEED® credits.

Credit 2.2. Implementation of start-up in the building: switching to air filters with lower pressure loss is one of the easiest ways to reduce energy costs. Provides 2 LEED® credits.

Credit 3.2. System performance measurement: implement ventilation air, static pressure, and air volume devices. Provides 1 to 2 LEED® credits.

Credit 6. Report on reduction of emissions: use a tool to determine energy savings and CO2 reduction by using filters with lower pressure loss. Provides 1 LEED® credit.

Materials and Resources.

Credit 1. Sustainable purchases/recurring consumables: the purchase of these technologies extends the life of filters, and reduces maintenance and the generation of waste, while minimising pressure loss and increasing energy efficiency. Provides 1 LEED® credit.

Indoor Environmental Quality

Credit 1.1. Best IAQ Management Practices. IAQ management programme: specify filters with the appropriate certified efficiency to reduce and/or eliminate particles and gases in the building. Provides 1 LEED® credit.

Credit 1.4. Best IAQ Management Practices. Reduction of particles in air distribution: install MERV13 or higher filters, establishing and periodically monitoring the replacement of filters. Provides 1 LEED® credit.

Credit 1.5. Best IAQ Management Practices. IAQ management for small renovations: install MERV8 filters in each AHU return grille, if these are used during construction, and replace all filters to sweep indoor space with ventilation air prior to occupation. Provides 1 LEED® credit.

Property owners or building managers interested in increasing the energy efficiency of their asset or obtaining LEED® certification must really pay attention to air filtration and obtain a LEED® certification. This is a voluntary exercise through which a property is objectively granted a level of sustainability.

The main advantages of having a Green Building are the following:

  • The sale price is 10% higher.
  • They consume 26% less energy.
  • Maintenance costs are 13% lower.
