Sports arenas attract vast attention with their aesthetic qualities, luxurious amenities, association with high-profile teams and iconic imprint on city skylines. But did you know that beyond their opulence, many modern arenas represent leadership in sustainability? “Many sports venues have jumped on the sustainability bandwagon to construct or renovate their structure in a race to minimise their carbon footprint, preserve their green legacy and take the lead in innovation,” says London-based Climate Action, which partners with business, government and public entities on sustainability projects. Sports arena sustainability is a global trend. Examples include: The Johan Cruijff ArenA (formerly Amsterdam ArenA), home of the Ajax football club. The Netherlands’ largest stadium employs more than 4,200 solar panels and a wind turbine. Its main building includes an energy-generating escalator and an energy system powered by second-life batteries from used electric vehicles.Mercedes-Benz Stadium, where the NFL’s Atlanta Falcons play their home games. In November 2017, soon after it opened, Mercedes-Benz became the first professional sports stadium to receive a platinum Leadership in Energy & Environmental Design (LEED) certificate for meeting rigid standards for carbon, energy, water, waste, materials and other factors. The arena’s energy consumption is reportedly 29% less than what the average stadium consumes thanks to LED lighting and 4,000 rooftop solar PV panels. A stormwater management system can store over 2 million gallons onsite, preventing flooding in surrounding areas.Levi’s Stadium in Santa Clara, Calif. The home of the NFL’s San Francisco 49ers since 2014 has earned two LEED certifications, including the first Gold LEED certification awarded for a stadium that hosts a professional team, plus a second Gold certification for operations and maintenance. Levi’s also incorporates 1,000 solar elements and sources 78% of its food from within 150 miles of the stadium. Seattle’s Climate Pledge...

It’s never too late to give an existing structure a greener lease on life. Retrofits offer commercial building managers an opportunity to improve efficiency and drive cost savings. If you’re just getting started, the four retrofit methods below are a great starting point for sustainable practices. Observe, benchmark and improve your energy consumption. Monthly bills are not enough to accurately determine the efficiency of a commercial site. Retrofits connected to the internet of things (IoT) provide real-time insights into energy consumption. Explore usage based on subleased portions or the entire building. What’s best, you can implement IoT retrofits at a speed that matches your budget. Commercial managers often begin with submeters. Submetering offers insights into building performance while facilitating average savings of 2-5%. Implement supportive technology such as energy benchmarking to help you meet compliance regulations for ESG platforms like ENERGY STAR®. Promote water efficiency regardless of your location. Dry, arid regions have long prioritized end-user water conservation. Interest has grown nationwide: efficiency offers economic benefits to all managers regardless of the site’s location. Retrofits for cooling towers and chillers are a great place to implement efficiency measures. Such retrofits will have the most notable impact since they can consume tens of thousands of gallons each day. Smaller projects, such as fixtures, may follow. Streamline HVAC operations to reduce waste and increase comfort. The efficiencies of HVAC systems decline naturally over time. Promoting optimal operation and occupant comfort requires consistent maintenance and smart controls. Networked controllers and cloud-based management software enable you to monitor and manage usage. Smart thermostats and monitoring technology can offer up to 30% energy savings while slashing future maintenance costs. Improve indoor air quality (IAQ). Americans spend about 90% of their time inside. Indoor air contains a higher concentration of...

Global energy demand surpassed pre-COVID 19 levels in 2021. Energy was the top-performing S&P 500 sector that year. With energy demand still on the rise, the energy sector stands to grow even more in 2022. The Balance Sheet sampled expert predictions of what’s ahead for renewables and the rest of the energy industry in 2022. We will keep tabs on key developments throughout the year. Economist Intelligence, a policy analysis and consulting group, predicts that global energy consumption will rise by 2.2% in 2022 as economies recover from the pandemic. All types of energy except nuclear power will benefit, although “energy companies will need to undertake an urgent review of their strategies next year, as governments and investors ramp up pressure to cut emissions.” Kathryn Downey Miller, president of energy industry analysis firm BTU Analytics, echoes that assessment. “Despite a strong profit outlook heading into 2022, enormous pressure is coming from providers of capital and other stakeholders to evolve business models for the new energy economy,” she said in an editorial published in December. That pressure is a principal reason that “renewable energy growth is poised to accelerate in 2022, as concern for climate change and support for environmental, sustainability, and governance considerations grow and demand for cleaner energy sources from most market segments (residential, commercial, and industrial consumers) accelerates,” according to an energy industry outlook report prepared by Deloitte. Renewable generation expands Renewables were the only energy source for which demand increased in 2020, according to the International Energy Agency. Renewable electricity generation in 2021 expanded by over 8% in 2021. Record levels of wind and solar generation additions are expected to come online in 2022, according to S&P Global Market Intelligence, which studies energy markets. The adoption of renewable energy sources will be...

It started with Green Lights. That was the U.S. Environmental Protection Agency’s (EPA’s) inaugural Climate Partnerships Programs initiative in 1991. Since then, Climate Partnership Programs has engaged tens of thousands of public and private organizations, generated billions of dollars of investments in energy efficiency and clean energy, saved American consumers more than $500 billion in energy costs and prevented more than 6 billion metric tons of greenhouse gas emissions. Green Lights – which encourages organizations to use energy-efficient lighting technologies in their offices, factories, stores and warehouses – is one of more than two dozen Climate Partnership Programs. Vital to meeting national greenhouse gas reduction, carbon-pollution free electricity and net-zero emissions targets, the programs include: ENERGY STAR®, which identifies energy-efficient products and practices for consumers and businesses in 33 industrial sectors and 840 utilities. Since 1992, ENERGY STAR, managed jointly by the EPA and the U.S. Department of Energy, and its partners have helped American families and businesses save 5 trillion kilowatt-hours of electricity, avoid more than $450 billion in energy costs and achieve 4 billion metric tons of greenhouse gas reductions. In 2019 alone, ENERGY STAR drove reductions of 220,000 short tons of sulfur dioxide, 220,000 short tons of nitrogen oxides, and 27,000 short tons of fine particulate matter. ENERGY STAR product sales exceed $100 billion annually.The State and Local Climate and Energy Program, which offers free tools, data and technical expertise to help state, local and tribal governments achieve their environmental, energy, equity and economic objectives.The Green Power Partnership, a source of information and technical assistance for companies using green power. The program has helped prevent nearly 280 metric tons of greenhouse gas emissions.Methane Emissions Reduction Partnership Programs, which promote the cost-effective recovery and use of methane by sectors such as agriculture,...

The Advanced Research Projects Agency-Energy, which performs R&D for the U.S Department of Energy, sponsors initiatives by businesses and academic institutions to improve energy efficiency.  Here’s the latest of our periodic summaries of active ARPA-E projects. Creating a new version of wood Alternative materials creator InventWood of College Park, Md., is working to develop lightweight 3D corrugated honeycomb structures to replace metal counterparts. 3D wood has one-third the density and one-fourteenth the cost of aluminum with the same mechanical strength. And the proposal could produce a big sustainability benefit as well – a 90% reduction of CO2 emissions in the manufacturing process. Adding the human touch to energy savings About 75% of U.S. homes have smart meters, according to Smart Energy International. While giving homeowners greater access to their energy-use data is a positive step, a team Stanford University researchers believes that optimizing energy and cost savings with that information will “require an understanding of human behavior.” Using human behavior to optimize energy and cost savings could “transform the way Americans interact with our energy-use data,” the team says. A custom-built web-based platform collects historical electricity data for experiments to learn what triggers homeowners to respond. The experiments include financial incentives and a calculator that illustrates the potential savings of efficient appliances. Once completed, the platform and new behavior experiments could help homeowners save energy, improve their energy efficiency and reduce utility bills. Making the power grid cleaner ARPA-E is funding four projects to develop technology to remove sulfur hexafluoride, a gas that’s utilized as an electrical insulator and arc suppressant, from the U.S. power grid. It’s a more potent greenhouse gas than carbon dioxide. Proposals from the funding recipients – the University of Connecticut, Georgia Tech, GE Grid Solutions of Charleroi, Pa., and...

On Oct. 6, Energy Efficiency Day addressed a topic with vast local, regional, national and global implications throughout the year. Yardi was pleased to observe the event with more than 800 local governments, universities, organizations, corporations and utilities. This year’s event coincided with the 30th anniversary of the U.S. Environmental Protection Agency’s (EPA’s) climate partnerships program, a collaboration between private and government organizations that has prevented more than 6 billion metrics tons of greenhouse gas emissions – more than all U.S. carbon dioxide emissions in 2019. “Energy efficiency is the cheapest, quickest way to meet our energy needs, cut consumer bills and reduce pollution. Energy efficiency is also an economic engine, supporting over two million jobs nationwide in manufacturing, construction and other fields,” according to the Energy Efficiency Day organization’s website. Energy Efficiency Day, an early-October fixture since 2016, promotes awareness by encouraging home and business energy audits, energy-saving competitions, success story sharing using the #EEDay2021 hashtag and more. Participants seek to promote easy-to-implement measures for businesses and individuals, including: Scheduling regular inspections for refrigeration equipment, furnaces, heat pumps and other equipment.Turning on computers, monitors, printers and fax machines only when they’re needed.Locating and sealing air leaks around the house. Even hidden drafts can hurt your energy efficiency.Staying cool in school. Did you know that the average 200-square-foot dorm room can generate as much greenhouse gas pollution as the tailpipe emissions of a car driven more than 2,000 miles? Consider setting rooms with individual temperature control a few degrees higher to reduce the cooling system’s energy use.Purchasing home appliances carrying the ENERGY STAR® label, which certifies adherence to strict EPA energy-efficiency standards.Turning off lights when leaving the room and consider swapping regular light bulbs for LEDs.Running ceiling fans clockwise and at low speeds during...

Are energy efficient features the norm or the exception in your state? How can that impact your property performance and marketing? We’ve got the inside scoop for you as we dive into the latest report on energy efficiency by state. WalletHub report offers insights into energy efficiency by state Personal finance company WalletHub released a report that gathered and analyzed data from government agencies in the continental U.S. Researchers considered data on automobile and building efficiency. States were then ranked in those categories, as well as overall efficiency. Operating within a high-efficiency state has its benefits. The report concludes that household and community-level increases in energy efficiency “decrease long-term costs for everyone.” Increased efficiency translates into energy savings and more resilient buildings and cars as well.   Best and Worst Overall Utah ranked #1 in overall energy efficiency, receiving a score of 83.91 points out of 100.  New York was hot on its tail with 82.05 followed by Massachusetts and Minnesota. Rhode Island wraps up the top five most efficient states with 76.45 points. The south is home to the least energy efficient states, with South Carolina leading the pack with a 21.49. With increasing efficiency comes West Virginia with a 24.20 proceeded by Alabama, Tennessee, and Louisiana at 31.22. Best and worst housing efficiency Among residential properties, Utah re-appears on the list as most efficient at 83.91. This time, it is trailed by Minnesota, New York, Colorado and Vermont. South Carolina also reappeared on this list as the worst in-home energy efficiency. Alabama, Tennessee, Louisiana and Georgia were also nestled at the bottom of the list as well. While local incentives impact efficiency measures during development and construction, there are other ways to promote efficiency. Building operators can improve building efficiency through ENERGY...

The residential real estate sector is going to see a few changes in the near future as businesses continue to open up their office environments, travel and immigration resume to pre-pandemic levels and Canadians gain a sense of confidence in venturing out of their homes on a more regular basis. Though human interactions will see a subtle shift from the pre-pandemic era, how residents use their living spaces will continue to evolve. This is an opportunity for real estate companies to re-evaluate the ways in which they manage their properties. Regardless of their approach to marketing, resident relations and other operations – the value of a viable energy strategy is gaining importance in the Canadian real estate sector. Residential property owners can increase asset values, boost stakeholder satisfaction and ensure compliance by adopting smart energy consumption practices. That’s best done strategically, especially as costs remain under heavy scrutiny and ESG accountability assumes ever-greater importance. First step: Utilize utility data to minimize costs Understanding and documenting energy consumption across a portfolio should be the first step in building a value-add energy strategy. Why? Because this operational area is one of a property’s largest controllable operating expenses. Understanding and harnessing utility data can make a property more valuable, more likely to retain residents, more easily marketed for sale, more compliant and more attractive to prospective tenants and investors and less likely to require concessions to rent. Advanced automated utility expense management systems also reduce duplicate payments, late fees, system interface errors and inaccurate spend measurements. They replace the cumbersome process of tracking consumption in excel, and wading through stacks of paper utility bills with digital invoice transmission and automated usage validation. Along with creating a single solution for invoice tracking, payments, budgeting and reporting, these systems...

Even as pandemic-driven lockdowns and stay-at-home mandates curtailed energy consumption in 2020, organizations in all types of industries remained focused on impactful conservation initiatives. Here’s a look at some of the companies that joined Yardi in receiving a 2021 ENERGY STAR® Partner of the Year Sustained Excellence Award, the highest honor bestowed by the U.S. Environmental Protection Agency and the U.S. Department of Energy for initiatives that reduce energy consumption and mitigate climate change. BENTALLGREENOAK. Along with achieving ENERGY STAR certification for 81 properties, the Seattle-based global real estate investor continued benchmarking its assets’ sustainability performance against internal best practices and peers. BentallGreenOak also used ENERGY STAR metrics to measure the success of its energy efficiency strategies. FOOD LION INC. The Salisbury, N.C.-based retail grocery store chain expanded its LED lighting retrofit program to 32 stores, saving more than 9.2 billion BTUs annually. It also earned ENERGY STAR certification for 919 stores, which encompass 89% of its portfolio. HEXION INC. The Columbus, Ohio, producer of thermosetting resins, coatings, adhesives and specialty resins executed 52 energy projects that produced $2 million in savings. It also conducted treasure hunts at 23 sites that identified 131 potential projects.

INC.  The pharmaceutical and healthcare company issued a letter of intent to purchase 60 MW of solar energy, matching the amount purchased in 2019. The Kenilworth, N.J.-based...

The following information is courtesy of the Energy Information Administration, a statistical and analytical agency of the U.S. Department of Energy that collects, analyzes and disseminates energy information. Post-COVID consumption lags The U.S. will likely take at least a decade to return to 2019 levels of energy consumption and carbon dioxide emissions due to the impact of COVID-19 on the economy and global energy sectors. “The pandemic triggered a historic energy demand shock that led to lower greenhouse gas emissions, decreases in energy production, and sometimes volatile commodity prices in 2020,” says Stephen Nalley, the EIA’s acting administrator. Around the world, global demand for petroleum products in 2020 fell by 9% from the previous year. Just how long it will take production and consumption levels to return to their pre-pandemic levels depends on a range of factors including the pace of economic recovery, advances in technology and government incentives. “It will take a while for the energy sector to get to its new ‘normal,’” according to Nalley. Battery power charging up A significant number of battery energy storage systems will be added in the U.S. between now and 2050, at which time 59 gigawatts (GW) of battery storage will serve the power grid. Falling battery costs, growth in non-dispatchable renewables (such as solar and wind, which can’t be turned on or off at will) and tax credits are the key drivers of the capacity expansion. Wind becomes a force In 2019 and 2020, developers in the U.S. installed more wind power capacity than any other generating technology. Wind turbine capacity additions in 2020 totaled 14.2 GW, surpassing a record that had stood since 2012. The impending phasing out of the full value of the production tax credit spurred investments in this technology. Congress extended...

Buildings account for 72% of the United States’ electricity use and 40% of the country’s carbon dioxide emissions each year. The Advanced Research Projects Agency-Energy, which carries out R&D for the U.S Department of Energy, sponsors initiatives by businesses and academic institutions to improve buildings’ energy efficiency. Here’s a summary of some active ARPA-E projects. Promoting a healthy cold According to ARPA-E, 5% of CO2 emissions come directly from air conditioning, which uses refrigerants that are greenhouse gases. American Superconductor of Ayer, Mass., is developing a freezer that doesn’t rely on harmful refrigerants and would operate more energy-efficiently than conventional systems. American Superconductor proposes to use helium gas as the cooler’s refrigerant, superseding liquid refrigerants that are eventually pumped out to the external environment. The eventual goal is the cost-effective mass production of high-efficiency freezers that do their job without pollution-generating refrigerants. Efficiency in motion A team at Boston University is developing an occupancy sensing system designed to estimate the number of people in commercial spaces and monitor how that number changes over time. The proposed system would generate occupancy estimates using advanced detection algorithms that interpret data streams from sensors and cameras. The occupancy data would enable the building control system to manage the heating, cooling and air flow to maximize building energy efficiency and optimize comfort. This could go a long way in making Boston office space, indeed office space across the world, more efficient. The project could “dramatically reduce the amount of energy needed to effectively heat, cool and ventilate buildings without sacrificing occupant comfort,” ARPA-E says. New pane, new gain Single-pane windows that are present in many buildings don’t insulate as well as double-pane units. Unfortunately, replacing them with newer, more efficient windows isn’t always feasible because of costs, changes...

Here’s a roundup of recent reports from the Energy Information Administration, the statistical and analytical agency within the U.S. Department of Energy: Wind power flies high in 2020 Project developers expect more than 23 gigawatts of wind turbine generating capacity to come online in the U.S. in 2020, far more than the previous record of 13.2 GW added in 2012. The impending phase-out of the full value of the U.S. production tax credit at year’s end is leading to more capacity additions than average this year, just as previous tax credit reductions led to significant wind capacity additions in 2012 and 2019. Texas has the most wind turbine capacity among states, with 29.1 GW installed as of August 2020 and another 4 GW expected by the end of the year. Wind’s share of U.S. electricity generation increasing from 7.4% in 2019 to 8.8% in 2020 — more than any other renewable electricity generation source. That share is expected to reach 10.3% in 2021. CO2 emissions reach lows In 2020, carbon dioxide emissions from the U.S. energy sector could be 11% lower than in 2019, according to data collected through August and estimates through December. CO2 emissions are expected to fall by 19% for coal, by 13% for petroleum and by 2% for natural gas. Many of this year’s changes in energy-related CO2 emissions are attributable to COVID-19, including working from home, stay-at-home mandates, closed or limited operating hours for several types of businesses and travel restrictions. In April, monthly U.S. energy consumption fell to a 30-year low and emissions reached a record low. Winter bills holding steady U.S. households that primarily use natural gas or electricity will have slightly higher energy expenditures this winter, with households using propane spending 14% more and those relying...

Some industries, such as technology and online media, are doing well amid COVID-19, even as the pandemic cuts a swath through virtually every public health, political, social and economic structure. Other segments of the economy, such as travel and hospitality, face a perilous future. And what about the vital energy sector? Before the pandemic hit, energy demand was projected to grow 12% between 2019 and 2030, as developing nations broadened their power generation capacities. But COVID-19 “has brought the generation of energy from fossil fuels to breaking point,” says the World Economic Forum, with global energy demand declining by 5% in 2020. Despite a larger population and world economy, demand in 2050 will be about the same as it is today, according to risk management and quality assurance experts DNV GL, due partly to the effects of COVID-19. “The scale of the fall in demand, the speed of change, and how widespread it has been have generated a radical shift that seems to be more than a temporary short-term drop in demand for fossil fuels, at least in the power sector,” Nelson Mojarro, a World Economic Forum advisor, said in June. That development has opened the door for renewable energy generation to play an even more prominent role on the world energy scene. Renewables, including solar, whose cost has fallen by 82% over a decade, are the lowest-cost source of new power generation, according to the International Renewable Energy Agency. That trend is expected to hold over the foreseeable future. And COVID-19, Mojarro says, “has had a game-changing effect in accelerating the clean energy transition in the power sector.” Within 10 weeks of the start of widespread lockdowns, according to data compiled by the International Energy Agency, the U.S. increased its renewable energy consumption...

The cost of water can be deceptively low — it doesn’t include the energy expenses of pumping and heating the water. When you evaluate water and energy efficiency together, you’re in a better position to maximize resource and cost savings. Multifamily companies can get some quick wins with minimal effort and no (or low) capital expenditure. All you need to do is make some changes to operations and maintenance practices along with minor retrofits or replacements as needed. The Environmental Protection Agency’s (EPA) WaterSense program recently shared strategies to save energy and water in the webinar “Reducing Costs with Quick Water Wins.” WaterSense is a voluntary program launched by the EPA in 2006 that provides a simple way to identify water-efficient products, programs and practices. In the webinar, the EPA’s Tara O’Hare highlighted the connection between water and energy, often referred to as the energy-water nexus, since every gallon of water has an energy footprint for pumping, moving, heating and treating water. To keep costs low, WaterSense offers the following tips: Review all bills for accuracy Check facility rate class and water meter size on bills Work with your local utility to correct any problems Identify leaks and waste O’Hare said that energy and water leaks linked to continuously running water comprise approximately six percent of water use and that potential financial losses from water such as a drip irrigation malfunction or an unattended water hose at night can amount to $4,300 or $16,000 per year, respectively. How can you make sure this doesn’t happen at your property? Conduct a walk-through to identify leaks (look for puddles and drips) and ask for the vigilance of employees and tenants to help identify leak and waste indicators as soon as they occur. Follow best practices You’ve...

In March, the U.S. Environmental Protection Agency awarded Yardi one of 191 ENERGY STAR® Awards for 2020 for national leadership in creating cost-saving energy efficient solutions. The company earned its second consecutive ENERGY STAR Partner of the Year Award, EPA’s highest level of recognition, for helping clients benchmark energy and water usage, widely promoting ENERGY STAR resources and earning ENERGY STAR certification for its corporate headquarters. And what did the other 190 award winners achieve? Their initiatives show that organizations in every sector of the economy – whether a real estate services leader, industry trade association, toothpaste manufacturer, baked goods pacesetter, top-tier university, venerable automobile manufacturer or aerospace behemoth – can find ways to protect the environment and save energy. Here’s a sampling of the most recent ENERGY STAR Award winners: Global commercial real estate services provider Cushman & Wakefield gave its tenants more than 20 presentations on implementing energy efficient practices and using ENERGY STAR-certified equipment. The company also trained vendors, brokers and building contractors in energy management goals and in using ENERGY STAR as a market differentiator. Cushman & Wakefield achieved ENERGY STAR certification for 130 buildings in 2019. BOMA International, a trade association for commercial real estate professionals, completed Year 2 of its W2 Challenge, an initiative to benchmark water use and waste output that was built with the support of a grant from Yardi. The organization also continued its ENERGY STAR-related education and recognition programs in 2019 and prominently featured ENERGY STAR in its videos, industry conferences, magazine, e-newsletters, webinars and social media. Bimbo Bakeries USA, whose brands include Thomas’, Sara Lee, Arnold and Entenmann’s, reduced energy use by 2.3% from the previous year and became the first major baking company to purchase renewable energy for 100% of its electricity...

Along with tracking the momentous public health and economic implications of COVID-19, renewable energy advocates are keeping a close eye on how the pandemic is affecting the Earth’s environmental well-being. The International Energy Agency, which advocates for sustainable energy policies, reported that average global road transport activity fell by 50% of the 2019 level in the first quarter of 2020, while aviation activity declined 60%, spurring an unprecedented decline in world oil demand. The U.S. saw a 50% reduction in the use of jet fuel and 30% less gasoline consumed; meanwhile, natural gas use in commercial and residential buildings dropped by almost 20% from late March to early June of this year, according to a study of COVID-19’s effects on energy and the environment by researchers from the MIT Sloan School of Management, Yale University and Northwestern University. Reductions spark optimism “Overall, these reductions reflect a 15% total reduction in daily CO2 emissions, which is the largest annual percentage decline for the U.S. in recorded history,” says MIT Sloan professor Christopher Knittel, one of the researchers. The recent drop in consumption and emissions offers a glimpse of a cleaner future – if the effort is sustained after the crisis abates. In the wake of COVID-19, “it is essential that we build back better. We need to create a more resilient and sustainable clean energy system in order to reduce the risk of facing the catastrophic crises that climate change could bring,” says Jules Kortenhorst, CEO of the Rocky Mountain Institute, writing for the World Economic Forum. That means prioritizing structural changes that “make a real difference for the energy transition in the longer term” rather than jumping on “the bandwagon to push the green agenda in short-term relief packages,” say researchers from ETH Zurich’s...
