• Latest Architect’s Guide For LEED Certification Checklist 2023

    In order to design a green building, architects require an updated version of the LEED Certification Checklist, i.e., LEED v5. Leadership in Energy and Environmental Design, aka LEED, is the most popular green building rating system in the world. A LEED Certification Checklist simplifies referring to and building environmentally conscious buildings while honouring architects for the same.

    Since its inception in 1993 by the USGBC, there have been more than 100,000 projects in about 180 countries. Considering India, there are 146 buildings, and it ranks third in the Top 10 countries in 2021. For this purpose, there are four levels of certification given to deserving buildings: Certified, Silver, Gold, and Platinum.

    As a result, the LEED Certification Checklist on the USGBC website might be quite overwhelming. So, here’s a compact guide for your next LEED-rated building.

    How To Get A LEED Credential?

    As an architect or interior designer, one can step into the world of green design by obtaining a LEED Credential. Obtaining a credential can help one understand the rating criteria and make obtaining the certification much easier. LEED Accreditation can be made simple by utilising the exam preparation package offered by USGBC.

    According to USGBC, one must clear two levels, which can either be taken separately or together. 

    1.LEED Green Associate (LEED GA): 

    Clearing LEED GA is the first step to getting a certification. It assesses the general knowledge of green building practices. The examination will take place online, with the option to attempt it from a test centre or from home. The time duration is two hours with 100 multiple-choice questions.

    2.LEED Accredited Professional (LEED AP): LEED AP is an advanced level examination that focuses on five specialities based on expertise, which are as follows:

    1. Building Design + Construction (BD+C): Guidelines for new buildings and renovations of old buildings
    2. Operations + Maintenance (O+M): Guidelines for owners to measure maintenance and minor improvements after construction
    3. Interior Design + Construction (ID+C): Guidelines for interior design and renovations
    4. Neighbourhood Development: Principles for sustainable urbanism and smart growth of city planning.
    5. Homes: Guidelines for three-story or less single and multi-family residential structures.

    Similar to LEED GA, it gives an option to attempt from a test centre or from home.

    Minimum Program Requirement (MPR) For LEED Certification

    Here are the Minimum Program Requirement For LEED Certification:

    1. The construction must be in a permanent location. The project must not move at any point in its lifetime.
    2. The project must adhere to LEED boundaries, which include all kinds of land that are part of the project, such as parking, sidewalks, septic tanks, etc.
    3. The project must meet the minimum area requirement according to the LEED Project typology. For that, one must understand the various categories and decide accordingly.

    Getting Started With A LEED Project

    Once you become a LEED-accredited professional, you need to decide the project category. There is a LEED category for every project:

    1. Building Design and Construction (BD+C): Minimum of 1,000 square feet (93 square metres) of gross floor area.
    2. Interior Design and Construction (ID+C): Minimum of 250 square feet (22 square metres) of gross floor area
    3. Building Operations and Maintenance (O+M): Minimum of 1,000 square feet (93 square metres) of gross floor area.
    4. Neighbourhood Development (ND): Not larger than 1500 acres and must contain at least two habitable buildings.
    5. Homes: Must be defined as “dwelling units,”, which include permanent provisions for living, sleeping, eating, cooking, and sanitation as per the International Residential Code.
    6. Cities: MPR is not applicable.

    Steps To LEED Certification

    Image Credits:

    1. Decide the LEED project typology or category for certification. This LEED Rating interactive tool can help you decide your project type:

    2. Select the right LEED Rating System using the 40/60 rule. The rule helps to choose the appropriate rating system when a project is applicable to multiple rating systems. It involves comparing the total floor area (TFA) of the project as follows:

    1. If Rating System TFA < 40% Project TFA: Rating System cannot be used
    2. If Rating System TFA > 60% Project TFA: Rating System can be used
    3. In case Rating System TFA is between 40 and 60 (example multi-use projects): The project team can decide

    3. After deciding, it is time to start a LEED project, which involves continuous evaluation. Visit the USGBC links for the following categories:

    1. Commercial (BD+C, ID+C, O+M): LEED Certification Commercial
    1. Neighbourhood Development: LEED Certification Neighbourhood
    1. Residential/ Home: LEED Certification Residential
    1. Cities and Communities: LEED Certification Cities

    4. To know more about the points for each criteria, refer to the credit library: LEED Credit Library

    To conclude, keeping a LEED Certification Checklist in hand can help make designing green buildings much easier. When it comes to green design, LEED Certification is credible proof for your clients that the building adheres to sustainability standards. LEED has various proven benefits to not just the environment but also the owner, as it will increase the value in the market.

    But should LEED Certification be the prime measure for sustainable design?

    The aim must not be to cross out each criteria in the LEED Certification Checklist, as it might miss out on the human touch. As long as the architect is true to one’s ideology of a green future, the design will naturally be sustainable.
