"Sustainability"! We keep on hearing the term these days, across almost every industry.
For us in the construction industry, we can see it actively becoming a mainstream approach. Well, our industry accounts for atleast 37% of global carbon emissions, says a 2023 research from the UNEP (United Nations Environment Programme).
While successful efforts have been there in the built environment to reduce operational carbon from heating, cooling, and lighting, any steps to control the process-embodied carbon have lagged behind.
This carbon comes from the design, production, and deployment of building materials and the construction process of non-LEED certified buildings.
However, in various regions across the globe, prominent innovations are being made to craft sustainable alternatives to traditional concrete, steel, and iron. Additionally, construction processes are also getting eco-friendlier with emerging technologies and machinery.
Sustainability regulations globally now determine the sustainability factor of any construction project. And LEED certification is recognized as a prominent sustainability credential for the design, construction, and operation of modern built environments.
Known by its acronym, LEED, the Leadership in Energy and Environmental Design certification is originally governed by the US Green Building Council (GBC).
Both firms and individual industry professionals can acquire this certification, going through a rigorous assessment by experts at the USGBC. Industry professionals with LEED certification are recognized as LEED green associates.
The credit library is an online database which holds detailed information on the prerequisites of a project to be considered as LEED project, and ultimately achieve the certification.
It is a free resource that guides project teams to identify their sustainability goals while aiming for LEED certifications.
Experts at the USGBC use the LEED credit library to track the number of environmental aspects, that an LEED project has addressed. Based on this assessment, the certification is provided on a four-scale rating system. This credit library, when utilized effectively by project teams, the chances for passing the assessment substantially rises.
The highest scale of certification can be achieved when all the requirements are stringently followed by the project. Let's uncover the rating system in detail to better understand the LEED requirements.
The LEED rating system for LEED certifications is divided into four sections: LEED Certified, Silver Certification, Gold Certification, and Platinum Certification.
These four levels span a maximum of 110 points, with:
Any project willing to attain the above certifications can start by fulfilling the criteria required for "LEED Certified". Thereby, they can further aim for higher points and achieve the Platinum Certification.
Also, as climate change propels faster, investors and customers get more interested in LEED certified buildings or construction.
Hence, LEED is one of the critical elements for modern construction projects.
Whether it is an infrastructure project, residential, commercial buildings or renovation of existing buildings, LEED is achievable by all. Once these types of buildings' design, construction, commercial interiors and operation align with the green building policies, the targeted level of certification can be obtained.
Accurate documentation is one of the key requirements of this process, apart from taking the required sustainable measures. The key areas where you need to demonstrate compliance are:
Site sustainability: Ensures that the project's surrounding environment is not affected, but instead valued and respected.
Water Efficiency: Efficient usage of water both indoors and outdoors, and preserving water resources nearby.
Energy consumption and Greenhouse gas emissions: Controlled usage of energy for operational activities, and active monitoring and reduction of greenhouse gas emissions.
Materials and Natural Resources: Verifies the use of natural-locally sourced materials for construction, and recycling materials to conserve resources.
Indoor environment quality: Adds credit to projects for the use of healthy materials, proper ventilation, limited usage of artificial lights, and optimal air quality for the occupants.
Overall Carbon Footprint: Ensures reduced overall carbon footprint by monitoring and lowering high energy consumption, energy wastage, and high fuel consumption.
With these key focus areas in mind, the last and most critical thing is proper documentation of the compliance addresses in these areas.
The first step is to identify the sustainability goals that you want to achieve through the LEED certification. However, let’s understand how LEED fulfills the sustainability goals on a global scale.
UNEP’s aim through LEED certification ensures that modern structures are both environmentally friendly and contribute to occupant health benefits. They have strategically framed the certification to address the following environmental aspects:
With technological advancements and continuous innovation in the field of material science, it is possible to achieve most of these. However, proper integration of the associated service is essential.
Hence, BIM takes up from here, offering a structured approach to achieve these goals seamlessly. Let’s uncover the role of BIM in helping you get different levels of certification from “Certified” to “Platinum”.
With Building Information Modeling (BIM) advancing rapidly, it becomes pivotal to fulfill sustainability goals.
While BIM offers several advantages across multiple categories, we will delve into the most impactful areas here. Let’s start with:
BIM workflows allow project teams to create 3D models that simulate energy flow in the structure.
Through this, they can optimize operational energy consumption, directly reducing carbon footprints. Further, BIM tools like Revit let you design efficient HAVC systems, and also enable the building’s design assessments for integrating renewable energy sources like solar panels, wind turbines, etc.
Since BIM offers you a virtual construction approach, engineers get the liberty to try and experiment with various water-efficient plumbing and irrigation designs.
Seasoned engineers calculate the water flow pressure and rates to design plumbing systems with minimal water wastage and maximum water energy efficiency.
Additionally, for structures with vibrant landscapes, BIM can spearhead the complete design and execution of landscape designs and irrigation systems. With the use of 4D BIM, designers can visualize rainwater harvesting systems, facilitating better integration into the building’s water system.
Material selection highly affects the sustainability factor of a structure. And BIM meticulously addresses this area, with material selection, design optimization for less material usage, and quantity takeoff.
BIM tools help in analyzing various construction materials’ environmental impact. Through its use, project teams can select sustainable materials based on the site conditions and weather.
A good amount of waste is also generated from over-purchasing materials. BIM helps in the precise identification of material quantities which aids in accurate procurement. This means no wastage of materials.
One of the very underrated yet effective way to enhance a structure’s sustainability is using BIM for site analysis.
Site analysis by BIM tools helps in understanding the topography, sunlight, and wind conditions. This enables better placement of buildings for less power consumption.
With the integration of BIM, you get complete control over the indoor environmental quality. This is also a critical scoring parameter for getting LEED certified.
BIM enables the simulation of the fundamental aspects of the indoor air quality, lighting, and thermal comfort.
It allows engineers to use precise data and calculate the placement of windows for maximum natural lighting while having minimum heat gain. This provides thermal comfort, using natural lighting during daytime, reducing the utilization of HVAC systems.
Each floor or room’s air flow can be simulated through advanced BIM tools, which leads to proper ventilation and fresh air quality.
For rooms or floors that require enhanced acoustics, BIM incorporates geometric and material data to simulate sound movement and predict reverberations and noise levels. Thus, it also helps in selecting materials that offer good acoustics naturally. The analysis is again linkable to a central BIM model, to incorporate the changes and improve sound quality substantially.
Even after fulfilling all the criteria for LEED, it is very critical to track and document all of that for fast approvals. BIM simplifies this by automating the tracking process and further shows the model data in LEED-specified format, helping engineers identify the gaps in compliance left.
Engineers can integrate BIM environments with LEED tracking software applications to achieve energy and environmental design. This provides a detailed visualization of the LEED credit progress. Every team involved in the project can view this and hence work towards fulfilling all the criteria with enhanced coordination.
Further, during operation, BIM supports the visualization of sustainability data through interactive dashboards. This helps in actively improving measures, adjusting specific systems, all aiming to achieve better scores.
With that, we finally covered the areas that impact your LEED score the most.
Now, let's see the steps you can follow to get LEED certified and even obtain higher levels of green building rating system.
With careful planning and proactive actions, it is not a hard nut to crack. The thing is moving forward with a structured approach, and these are what you need to do:
Projects looking forward to attaining LEED certification should be certain about their goal in the initial levels. You should define the level of certification you plan to achieve, and ensure that it is suitable for sustainable buildings.
As we have already gone through the different levels of LEED scores, it is very critical to determine, under which level your project falls. Each level defines a category, and based on your accreditation goals and project type, perform an assessment.
Usually, the standard way is to choose the category to which more than 60% of your project aligns, and avoid the categories where the alignment is 40% or less than that.
Once you have chosen the category, it is time to start the project. Execute the project following all the guidelines, selecting sustainable materials and eco-friendly construction methods.
Now comes one of the most critical steps, which is to get your project registered. There is a fee for each registration, the typical range of it being, $900- $5000. The range depends upon the project scale and the desired certification.
Once this is done, ensure that your project is complete and all the criteria required for your desired certification are met. With the help of an elite BIM service provider like Pinnacle Infotech, you can ensure 100% compliance and accurate project documentation. In this step, you need to submit the project documentation that clearly shows the areas you worked on for sustainability and getting LEED certification.
The U.S. Green Building Council will now review your project's sustainability standards and eligibility for LEED green building certification.
To conclude, LEED is the most credible certification defining a building's stringent compliance with sustainability. The USGBC governs the criteria of this certificate and imposes stringent guidelines for projects to pass their assessment. However, if you have read up to this, you might have understood that getting LEED certification with the help of BIM is far easier.
