LEED for Cities and Communities helps government leaders benchmark and enact sustainable changes in their municipalities. In the 2022–2023 school year, the rating system’s tenets will be used by university professors at the classroom level to prepare students for jobs in sustainable design, policy and development.

USGBC partners with colleges and universities interested in leading academic learning programs associated with the rating system. Professors design their own programs and collaborate closely with USGBC to implement them. In many cases, professors’ curriculums include a component of experiential learning that puts students in direct contact with the aforementioned government leaders, sometimes within their college neighborhoods. The result? Measurable, lasting impact made by students at the beginning of their sustainability careers.

Professors at the University of South FloridaClarkson University and Utah State University are making sustainable education accessible to undergraduate and graduate students, in addition to those seeking to bolster their understanding of sustainability.

University of South Florida

Florida hasn’t always had the best track record when it comes to sustainability.

“[Florida] could have actually been the Sunshine State. We could have been the leader in solar technologies, but instead we’re behind,” says Brooke Hansen, Ph.D., director of sustainable tourism for University of South Florida’s Patel College of Global Sustainability.

However, Florida’s status makes it the perfect place to apply a framework such as LEED for Cities and Communities to make the state more sustainable.

The Sunshine State currently faces a multitude of environmental issues: plastics pollution, transportation crises, climate change, the threat of Category 5 hurricanes and sea level rise. But Florida, like every place, is experiencing a critical moment—one in which the state can “build forward better” and heal, Hansen says. Education is an invaluable factor in doing that, which is where Hansen and the University of South Florida come into play.

Carbon cutters: Reducing emissions through material selection

Building operations can always be fine-tuned for optimal performance, but there’s no way to reduce the embodied carbon of the materials used to construct that building once they are installed. This means that there is a finite window of opportunity to lessen the embodied carbon of a new development using typical operations practices. However, the process is getting easier, as suppliers are now offering more sustainable options, including for the two most carbon-intensive materials in building construction: concrete and steel.

Portland cement fabrication accounts for approximately 8% of anthropogenic greenhouse emissions, due to the fossil fuels burned to heat raw limestone to incredible temperatures, as well as the carbon dioxide that off-gasses during this process. After years of research and development, the concrete industry has begun to offer lower-carbon mixes that replace some of that cement with lower-carbon materials. These products perform as well as traditional mixes, if not better, and often there is no increase to a project’s budget.

My firm, Lendlease, is developing The Reed at Southbank, a 440-residence tower that recently topped out in the South Loop neighborhood of Chicago, Illinois. This was our first project to create to meet an embodied carbon reduction target—in this case, 10%. After performing a life cycle cost analysis, we elected to work with our suppliers to reduce the embodied carbon associated with the concrete throughout the project.

Every slab and column in the building uses a proprietary concrete mix procured from McHugh Concrete, which developed the product in partnership with Oremus Material. This lower-carbon alternative substitutes approximately 60% of the Portland cement with ash and slag—manufacturing waste products that would otherwise end up in a landfill.

Women in Green: A rising collective in Northern California

Women in Green celebrate at the LEED Gold Salesforce Park.

In August, the USGBC Northern California Women in Green (WIG) committee organized a special summer program to in keeping with our theme of the “Rising Collective.” To celebrate our women leaders in the green building movement, we welcomed 25 inspiring USGBC Women in Green to join us in recognizing the LEED Gold Salesforce Transit Center.

We gathered in the refreshing atmosphere of Salesforce Park, a 5.4-acre public park and green space right in the middle of the SoMa neighborhood in San Francisco. The park has over 230 species of understory plants and 50 species of trees, making the setting for WIG a true biophilic environment. In addition to being an example of sustainability, the park provides a refreshing break from the day in downtown San Francisco and contributes to public health via its abundant green space, seating and an amphitheatre.

Women leaders sharing ideas

The event began with a special address by our host Nila Gonzales, chief of staff for the Transbay Joint Powers Authority and a San Francisco native who has devoted her career to serving the city. Her address was followed by our featured speakers, Pam Brandon, MEng, PE, SE, recently appointed the first female partner at AlfaTech group, and Susan Orlandi, principal and California regional workplace leader at DLR Group.

As women leaders in the industry, our speakers shared their insights on how we can strengthen togetherness, influence collective impact and provide opportunities for other women. Liesl Heil Morell, chair of the USGBC Northern California Women in Green Committee, moderated the event. This was followed with group discussions led by our Women in Green speakers and volunteer leaders, Payal Vora and Emily Alvarez.

Pro tip: Building on a budget

Q: How do I finance a sustainable building in a time of inflation?

We are currently going through a time of economic concern in construction projects because of inflation. In Colombia, we are finding that materials like steel, PVC, aluminum and copper have been subject to increases of around 80% since December 2020. This situation means that your building budget may be different from what you projected.

For some builders, that leads to cutting costs on things that are perceived as added value to their projects, like sustainability features and green certification, but the good news is that there are better ways to work on a budget. Here are some tips for speaking to your client about their options, learning ways to cut costs during the design and construction process, strategic planning, and marketing, so you can show the benefits to your budget-conscious counterpart.

1. Identify the most sustainable way to invest available resources.

You have a certain amount of resources at the moment, and now they tell you that they may not be enough. How can you create more with less? Sometimes we forget the importance of sitting down and going over the basics of our building and how it consumes energy or water:

Energy

Create an energy consumption pie chart for your base building that gives you an idea of where most of the energy is going to be consumed. Attacking that area will bring the best outcome. You should also take into account the proportion of the overall cost invested in sustainability, so you can decide using both variables. A useful formula for that would be:

% of energy consumption x % sustainability cost = cost-benefit index

This number should have a tendency toward zero, and the closer it is to it, the better the investment you are making. You can rank each measure and compare that to your available budget to find the investments you can and should make.

If you want to use a renewable energy analysis, the formula would be really similar, but this time with the projected savings on energy coming from the system and the percentage of sustainability cost, multiplied in the same way, so the rest of the analyses should be the same.

 

 

How do we get to zero carbon buildings?

Where are we now?

The recent report from the Intergovernmental Panel on Climate Change (IPCC) emphasizes that to avoid the worst impacts of climate change and limit global warming to the Paris agreement goal of 1.5°C, quick and comprehensive changes to the way we use power are required.

Decarbonization is a big word for a big goal: reducing or stopping carbon gases, especially carbon dioxide (CO2), from being released into the atmosphere and raising global temperatures. Working to reduce greenhouse gas emissions (GHGs) is nothing new for the green building sector, but bringing them down to zero presents new challenges.

Buildings and construction are responsible for about 30% of energy-related CO2 emissions globally. As USGBC’s building decarbonization issue brief shares, having clean energy technology and solid operations strategies in place isn’t enough; to make it all work, we also need broad buy-in, and that means sharing convincing data, empathizing with local priorities and getting supportive incentives and policies passed.

For buildings ranging from airports to schools, zero carbon plans are being put into place. There’s no time to lose in the fight to mitigate climate change. So, how do we get there?

What do we need to do to reach zero carbon?

1. Focus on the full life cycle of a building.

New buildings: Embodied carbon is what is released into the atmosphere as the result of constructing a new building. This can include extracting raw materials at the point of origin, manufacturing those materials into usable form, transporting them long distances, building a structure, and eventually, demolishing or recycling the materials at the end of the building’s life.

Existing buildings: Operational carbon is what is emitted when a building is in use and all systems are running​ and being maintained. It includes CO2 generated by powering the structure, operating heating and cooling, and running lights.

 

 

Carbon and its future within climate policy

Buildings and construction account for at least 31% of energy-related CO2 emissions globally.

Of that total emissions, some are what is called embodied carbon, and the rest are caused by energy used to operate buildings. Embodied carbon emissions are generated by the manufacturing, transportation, installation, maintenance and disposal of construction materials used in buildings, roads and other infrastructure, as defined by the Carbon Leadership Forum. Embodied carbon is an urgent concern for several reasons: First, a large part of embodied carbon emissions occurs during construction, which means that they hit the atmosphere by day 1 of a building’s life. Second, new construction is predicted to be significant, with global building stock expected to double within the next 40 years.

To understand which materials are high in embodied carbon, a reporting system known as Environmental Product Declarations (EPDs) assess a material’s environmental impact over the course of its lifetime through life cycle assessments. EPDs provide transparent reports that quantify a material’s impact throughout every stage of its use. Qualities assessed include global warming potential, acidification capabilities, ozone depletion and more. Through EPDs, the materials’ environmental degradation can be compared, and sustainable materials can be prioritized. Although EPDs are voluntary for most manufacturers, they are on the rise as individuals respond to the environmental harms of embodied carbon.

Other actions to lower and offset embodied carbon within the building sector include implementing carbon-sequestering materials and using fewer finishing materials, among others. For example, cement production is responsible for 7% of CO2 emissions annually; thus, switching to green alternatives like ashcrete and grasscrete can reduce emissions. Without reduction efforts, embodied carbon will account for 74% of the emissions from new construction over the next 10 years.

One recent step toward decreasing embodied carbon is the Inflation Reduction Act (IRA), signed into law on Aug. 16 by President Biden. The IRA aims to reduce total carbon emissions by 40% by 2030. The package proposes $433 billion in spending, of which $5 billion is allocated to low-carbon procurement for infrastructure. This funding will be distributed to various provisions in the bill, such as developing and standardizing EPDs; labeling and using low–embodied carbon materials; implementing low-carbon materials, technologies, and products to improve climate resilience within affordable housing; and providing financial assistance through the FEMA Building Materials Program to incentivize low-carbon and net zero energy projects.

 

 

4 ways to enhance your ESG strategy by using LEED

LEED Fellow Alicia Silva Villanueva shares how the rating system can help with ESG strategy.

Investors have realized that adding ESG criteria to their investment strategy is a must-have; however, it is never fully clear what the right path is. Adopting ESG criteria for your portfolio will potentially attract clients, but having a full, comprehensive sustainability strategy will certainly benefit all stakeholders in more impactful ways. In my experience greening real estate portfolios, these are four proven ways to enhance your ESG strategy by using LEED:

1. Let LEED serve as your road map for decarbonization.

Plenty of companies are pledging to reach net zero, but they can become overwhelmed by the challenge in practice. LEED serves as an amazing guide to achieving decarbonization, because it indicates what steps need to be taken with a systemic approach. One of the major misconceptions about decarbonization is that it only concerns energy, while some crucial aspects such as embodied carbon, transportation and waste are easily forgotten. LEED addresses the ESG question holistically, serving as a road map that will fulfill environmental and social criteria while also engaging in the adaptation and mitigation of climate risks. Embarking on the challenge is hard, but trusting in a well-laid plan like LEED will help us move toward accomplishing our science-based targets and net zero pledges.

2. Leverage the power of portfolio-level LEED.

Real estate portfolios need to overhaul their business models to adapt this new transitional economy. LEED volume programs assist in this transition by creating prototypes that dictate how new developments need to move forward, raise their standards and establish a new normal. Every portfolio is different, but we have found through our work that encouraging all the supply chain contractors and subcontractors to meet specific ESG criteria truly does help in making all strategies more efficient and effective. There is great comfort in seeing significant advancements happen with every project, without having to reinvent the wheel every single time.

3. Use LEED for existing buildings.

Having peace of mind when assessing how our assets are performing is invaluable, and there is no better way to start than with an audit. Surprise! That is the first step to achieving certification under LEED for Operations and Maintenance (LEED O+M). When covering audits in energy, water and waste, we really get to know where we stand in terms of how our assets are performing and where will investment serve better. Audits mark the difference because by identifying the key areas of improvement beforehand, real estate investors and tenants can anticipate where the savings generated by LEED O+M will be.

Teaching today’s change agents

Educators across the U.S. are integrating sustainability principles into their curricula.

Given the right resources, the green economy is poised to deliver change on nearly every industry front. There’s a growing market for clean energy technologies, net zero construction, low-carbon materials and software for modeling climate-smart development, to name a few of the areas where sustainability is taking shape.

“Sustainability” can be defined as a holistic approach to integrating environmental, social and economic benefits into human-generated goods and services. It is an adaptable, malleable concept readily applied to any field. It is a term that more and more industries are adopting in their communications; it signals intentionality around environmental and social stewardship. It is also a sign that the green economy is growing—and that economy needs a larger labor force.

It is incumbent upon educational institutions to equip their students with the kind of knowledge and skills needed to push sustainability not only forward, but in all directions, to reach every socioeconomic sector. Developing methods for teaching lessons—across all academic subjects—around sustainability that will impart both theoretical information and practical skills is the challenge.

Some high school educators have found solutions in USGBC’s LEED Green Associate Exam Prep-Take-Teach for Teachers, an online course begun in 2022. Its objective is to prepare educators to sit for the exam and teach them green building principles that they can then incorporate into their classes.

Finding a framework

Karen Carney, an instructor of environmental science and sustainable and renewable technologies at Battlefield High School in Haymarket, Virginia, found the prep course helpful. Her school is in an affluent suburb half an hour west of Washington, D.C. It has 2,500 students and is the only school in the county to offer a sustainability course.

The building decarbonization big idea: BlocPower in Ithaca

The City of Ithaca, New York, has signed a contract with a consortium led by BlocPower with the intent to decarbonize 1,600 buildings to start, with the goal of reaching 6,000 buildings by 2030. This one-of-a kind, public-private partnership has unique features that could become a model for other local governments. Take a closer look at how this program came about and how it will work:

Drivers

Ithaca has a long and deep commitment to sustainability. The city joined ICLEI-Local Governments for Sustainability in 2001 and subsequently joined the U.S. Mayors Climate Action Commitment and Climate Smart Communities pledge. Moreover, the city developed plans and implemented actions, such as a building energy code surpassing the state code.

Then, in 2019, the city council adopted the Green New Deal. Motivated in part by the 2018 Intergovernmental Panel on Climate Change (IPCC) 1.5 degree report, the council set forth the goal of achieving a carbon-neutral city by 2030 and committed to do so through specific actions, including green building policies for new buildings and for existing buildings.

Green building policy

More important, the city is following through on this commitment. In 2021, the city adopted the Green Building Policy for new construction and renovations as part of its energy code. The rules require that all new buildings be constructed to produce 40% fewer greenhouse gas (GHG) emissions than those built to New York State code, and ratcheting to 80% reduction in 2023 and ultimately to net zero, all-electric buildings in 2026 (with exceptions). The rules provide builders the options of a prescriptive path or a whole building path, which requires use of a listed green building system with the specified energy points. LEED is one such pathway, with 17 energy points.

 

 

More than 23 Million Square Feet of LEED Certified Net Zero Space

Milestone reflects growing demand for net zero buildings

June 14, 2022 (Washington, D.C.) – Today, the U.S. Green Building Council announced nearly 100 net zero certifications earned under the LEED Zero program, representing more than 23 million square feet of space. One-fourth of LEED Zero projects earned multiple certifications, demonstrating achievement of net zero goals in several categories.

A complement to LEED certification, LEED Zero provides a clear, data-driven path to recognizing net-zero goals and signals market leadership in the built environment. In 2018, the first year LEED Zero was released, certifications were earned in every category, with one project earning certification in all four categories.

“Operating our buildings at net zero, combined with a solid green building strategy, is a cost-effective solution to tackling the climate crisis,” said Peter Templeton, USGBC’s interim president & CEO. “Reducing the carbon emissions of buildings is a critical part of the solving the climate puzzle. We will continue to work together with building owners and partners from all sectors to ensure that we meet net zero goals.”

LEED Zero energy certification is awarded to net zero energy buildings and communities that generate as much energy as they use over the course of the year. LEED Zero Carbon recognizes net zero carbon emissions from energy consumption through carbon emissions avoided or offset over one year. LEED Zero Water recognizes a potable water use balance of zero over one year. LEED Zero Waste recognizes buildings that achieve GBCI’s TRUE certification at the Platinum level.

Recent years have spotlighted the need to reduce carbon emissions and accelerate efforts to achieve a low-carbon future. Buildings account for nearly 40% of all carbon emissions, and according to a 2020 UN report, buildings must reduce at least 50% of their carbon emissions by 2030 to achieve net zero by 2050. Organizations, cities and countries around the globe are now monitoring their outputs and committing to carbon emissions reductions as well as net zero emissions.
