The role of VRF system in LEED certification
Why we need sustainable buildings?
The need for sustainable buildings is increasing. LEED certification for buildings helps in reducing carbon emissions, water & energy conservation, reduce waste.
This result in saving the environment and achieve better life for building user, attract more tenants and increase the building value in the market.
Why LEED?
There are different types of green building certifications used around the world like: BREEAM , LEED?, WELL , Energy Star Certified Buildings, Pearl Rating System, Mostadam Green Building Rating System.
LEED is considered as the most popular certification program for green buildings around the world.
How to achieve LEED points by VRF system?
VRF system can achieve up to 33 LEED points for new buildings in the following LEED categories:
1-???Energy & Atmosphere
2-???Indoor Environmental Quality
3-???Innovation
4-???Regional Priority
1-???Energy & Atmosphere
VRF supplier must provide installation manuals and assist in startup and commissioning of the equipment and control system.
The control system is advanced and can provide energy management function using the “Central touch controller” to control and monitor the energy usage to achieve better energy management.

In case of multi tenant building, the building administrator can check the energy usage for each space using the power distributor indicator (PDI) and use this report in billing system and energy reduction.
Also, the heat recovery and heat pump systems can contribute in reducing the energy consumption.
2-????Indoor Environmental Quality
It is mandatory to achieve the requirements of indoor air quality (IAQ) at ASHRAE Standard 62.1-2010 or the local equivalent requirements.
The system can meet the (IAQ) requirements by wide range of solutions like the VRF total fresh air concealed indoor unit, ERV, and by connecting AHU with the VRF outdoor unit.
These solutions are used to achieve “Enhanced Indoor Air Quality Strategies” and occupants comfort.
The ERV system could be integrated with (Class 7) filter, The AHU could be integrated with higher efficiency filters according to the air quality stated at the standards. And in high density occupied spaces the co2 concentrations could be monitored using co2 sensor.
Also, to promote occupants productivity and wellbeing, it is important to meet the requirements of ASHRAE 55- 2010 by making sure that each indoor unit can monitor and control the temperature and humidity within the space to achieve the required comfort level.
3-???Innovation
VRF system is eligible to gain exemplary performance criteria.
4-?? Regional Priority
Achieving extra points by meeting the requirements for local environmental priorities.
Building developers and owners are always searching for solutions to evolve the real estate market and achieve sustainability. That impact on reducing the operating cost , increase the building value , better quality of life for the building occupants and reduce the environmental impact of the building
