How Daikin Fan Coil units contribute to Green Building Projects

Human activities, particularly the way we construct the built environment, can have a considerable impact by contributing to climate change and pollution, which represent a significant threat to the sustainability of our planet. 

The construction sector substantially contributes to these challenges by generating air pollution, impacting climate change, contaminating water sources, and generating waste in landfills. In this regard, the concept of Green Building emerges as a vital solution to mitigate the environmental challenges posed by the construction sector. Green Buildings are specifically designed to minimize or eliminate negative impacts on the environment, offering a proactive approach to combat climate change, conserve natural resources, and enhance the overall quality of life. 

These buildings employ processes that prioritize resource efficiency and environmental responsibility across their entire life cycle—from initial design and construction to ongoing operation, maintenance, renovation, and eventual deconstruction. By embracing Green Building principles, the construction industry can significantly reduce its environmental footprint and contribute positively to global sustainability efforts. 

In the context of building and environmental sustainability, energy efficiency plays a key role. It refers to how effectively a building uses energy to meet its operational needs, including heating, cooling, lighting and other energy requirements while minimising overall energy consumption. 

Achieving energy efficiency involves the integration of technologies, materials and design strategies.  A critical aspect of this is the implementation of efficient HVAC systems, that use advanced technologies to reduce energy consumption while maintaining optimal thermal comfort within the building. HVAC systems can determine buildings’ impact on the environment as they usually account for about 50% of the energy consumption.  

By prioritising energy efficiency in the design and operation of buildings, is not only possible to reduce operating costs but also environmental impact, contributing to a more sustainable built environment for future generations.  

Daikin’s main goal is to contribute to mitigating the impact that the Air Conditioning sector has on the environment by designing and producing technological solutions that can lead the way towards sustainability. 


How Daikin contributes to Green Building through Fain Coils 

Fan coils are devices used in HVAC systems to heat or cool air within a building.  

Fan coils are flexible in their installation and can be ceiling, floor or wall mounted, depending on the structural and design requirements of the building. This versatility allows for strategic placement to ensure efficient distribution of thermal comfort throughout the indoor space. These units are widely used in residential, commercial and industrial environments where precise temperature control and comfort are required.  

Daikin contributes to Green Building by designing and manufacturing energy-efficient HVAC products that prioritize environmental sustainability. Daikin Fan coil units (FCUs) are designed to optimize energy usage while maintaining thermal comfort, thereby reducing the overall environmental footprint of buildings.  


BREEAM & LEED certification 

Of course, green buildings must meet rigorous quality assessments based on specific rating systems that certify the minimal environmental impact of their design.  

Among the most well-known are BREEAM, which is widely used around the world, with over 200,000 buildings certified and more than a million registered for assessment, and LEED, which is particularly popular in the US and increasingly in the EU. 


Daikin Fan Coils’ contribution under BREEAM protocol 

BREEAM (British Research Establishment Environmental Assessment Method) is a certification system that recognises sustainable buildings that exceed national standards. As an internationally leading quality label, it provides investors and building owners the guidelines to focus on sustainability in building design as well as the environmental impact of products in buildings. The BREEAM label assesses the overall building concept in 10 distinct categories. Credits are awarded and weighted for each category to generate the final score for the building, in levels from ‘pass’ to ‘outstanding’.  

In terms of BREEAM credits related to Fan Coils, Daikin can provide up to +2020 credits, which are distributed in the following categories: 

Credits in Management 

Regarding Management category, Daikin can bring up to + 2 credits in the Commissioning building services and Handover assessment criteria, because it can provide installation manuals and a schedule of commissioning for the HVAC work, including an overview for commissioning and recommissioning.
