The U.S. Navy Bachelor Enlisted Quarters, designed and built by Wight & Co., was the first LEED-certified building to be constructed in Illinois. Since that time some 15 years ago, more than 1,000 LEED-certified spaces have been completed across the state. Today, Illinois is a recognized national leader in green building and sustainability know-how. This leadership is reflected in the advancement of innovative, cutting edge technological firsts, like the Evanston net-zero Walgreens and the recently completed Grainger data center in Lake Forest, the first LEED v4 certification anywhere in the world. Illinois consistently ranks in the top ten every year for the most LEED square footage certified per capita, leading the nation for three years in a row starting in 2013.

It’s tempting to assume that a landmarked building like the Rookery has been preserved in architectural amber. But the world-renowned structure isn’t exactly the one that Daniel Burnham and John Root designed in the 1880s. After the turn of the century, Frank Lloyd Wright famously applied a gilded eggshell cladding to the lobby. In the 1930s, William Drummond, formerly a Wright protégé, added Art Deco elements, including bronze elevators etched with birds matching the building’s moniker. The twelfth story was largely rebuilt in the 1990s when Burnham & Root’s original office was restored.
The latest changes to the building have been subtler. Like many other historic office buildings in the central business district, the Rookery has been busy for the last several years implementing sustainable strategies that will allow it to stay relevant for the next century.

For the third year in a row, global carbon emissions from the energy sector were flat, according to the International Energy Agency. What’s impressive is that this plateau in emissions comes at a time of economic growth around the world, suggesting that improved energy efficiency, renewable energy production and other factors are driving a decoupling of economic activity and carbon emissions.
However, the current level of energy-related investments needs to double to avoid raising the global average temperature by two degrees Celsius. That benchmark—two degrees Celsius—would still have a substantive effect on climate change, but is a goal preferable to allowing temperatures to climb without restraint. A separate report conducted by the IEA and International Renewable Energy Agency concludes that to avoid that temperature rise, emissions need to peak by 2020 and plummet from current levels by 2050.
Electricity is so integral to our lives, but humanity’s ever-growing need for it is defacing the planet. There are many ideas on how to stop this, but to have an effect, those ideas need to take root in the real world.

Four years ago, the Illinois Institute of Technology transformed into an island. The 50+ buildings that make up the Bronzeville campus were put on a microgrid—a network of buildings, batteries and energy sources that can be detached, or “islanded,” from the power grid.
The benefits of a microgrid are numerous. They can function independently when necessary, such as during a power outage. Energy efficiency is another advantage; through the use of solar and wind generation, the IIT microgrid reduces the university’s power consumption by $1 million annually and carbon dioxide emissions are trimmed by 7%. On-site batteries store excess electricity while sensors in and around the campus buildings track energy use for optimal deployment.

After three straight years at the top, Illinois has fallen to third on an annual ranking of green building projects in the U.S. The per capita list was compiled by the USGBC using U.S. Census data and commercial and institutional green building projects that were LEED-certified throughout 2016. Illinois totaled 151 LEED certifications last year, representing 2.82 square feet of certified space per resident.

Green Apartment Construction Blossoming, Yet Renter Survey Shows $560 Rent Premium is Five Times Higher than Most Would Pay
When it comes to trends in real estate, some are transient, and some are here to stay and shape the industry. Sustainable buildings are proving to be the latter. Their ubiquitous presence all over the country is possibly the best clue that green living is quickly going from niche to mainstream in real estate. Investors, developers, architects and consumers are realizing the importance and benefits of building by standards that meet the needs of present and future generations.

In 2015, Illinois added 11 MW of solar power production, which was a 75% increase over the previous year. While this growth is encouraging, the state remains middle-of-the-pack for overall capacity, ranking 27th in the nation. So what can be done to encourage more solar panel installation?
Part of the answer may be shared renewables. These projects allow multiple energy customers to pool their resources into a small—though still utility-size—renewable energy source. Each household or business then receives a share of the output, offsetting the power they pull down from the grid.
When speaking specifically of solar power generation, these projects are often referred to as “community solar.” A community solar farm is a collection of solar panels installed most often on public or jointly-owned property. They are usually ground-mounted, though they can be affixed on a roofscape under certain conditions.
There are various models for a community solar co-op. Some utilities offer on-bill crediting, wherein residents and businesses buy one or more shares of a renewable farm and receive a credit on their energy bill. Under another model, some utilities allow customers to purchase a set amount of electricity at a fixed rate from a shared facility for a long, multi-year term. Utilities aren’t a prerequisite partner, however; community members can form a special purpose entity to develop a community solar project.
Despite the dropping cost of solar, it remains a cost-prohibitive project for many small businesses and homeowners. But there are other factors that would impel individuals from taking part in a community solar project, aside from cost. Renters and condominium owners don’t have domain over their roof and therefore can’t install solar panels. Even for property owners, the roof may be in the shade or oriented in a way that is not optimal for solar power harvesting. Even if a commercial building avoids those obstacles, it might be exempt because of mechanical equipment occupying too much of the roof real estate.
According to the Solar Energy Industries Association, there are more than 90 community solar projects up and running across 25 states. There is only one operation in Illinois, in the northwestern community of Elizabeth. The South View Solar Farm is operated by Jo-Carroll Energy, a member of the Touchstone Energy Cooperatives alliance.
Constructed in 2014, South View Solar Farm occupies three-quarters of an acre in Jo Daviess County. The array consists of 456 solar panels and has a capacity of over 125 kW. Subscribers purchased a minimum of one panel for $890, and each panel has a capacity of 275 watts. Subscribers receive around $50 per year per panel in utility credits, with an estimated return on investment of about 18 years.
Mapping Cook County
Thanks to a new, interactive map developed by the Cook County Department of Environmental Control and non-profit organization Elevate Energy, the potential for community solar in the Chicago region can now easily be ascertained. The parcel-level map allows users to do more than search the county by address; filters can fine-tune the information by property type, solar power potential, roof type and municipality or Chicago neighborhood.
Every viable site provides an estimate of the annual electricity generation that a solar array could provide if installed there. As alternative metrics, the site breaks it down to the number of homes an installation could power per year and the carbon offset in tons CO2 emissions.
“I think this project demonstrates the opportunity [for] all the various stakeholders—utilities, local government, developers, community planners and community members themselves—to begin to visualize what their role in a future solar economy might look like,” said Anne Evens, CEO of Elevate Energy.
After gathering the data, it became clear that only a quarter of Cook County households can viably install solar panels. Myriad reasons prevent the majority from doing so. Some rooftops are in the shade of other structures or face to the north. Many residents live in a multi-housing unit where they don’t own the roof or lack the financial means to front a solar installation.
In recognition of this, the Cook County Community Solar Portal is more than a map. It also provides business models, case studies, educational resources and other information on community solar. “The solar developers will tell you that the larger the better. But we’re looking at sites as small as 25 kW,” said Deborah Stone, Director of the Cook County Department of Environmental Control. “That size diversity is what’s going to help community solar succeed in Cook County.”
Cook County Board President Toni Preckwinkle has committed to reducing the County’s greenhouse gas emissions by 80% by the year 2050. As solar energy would be a critical way of reaching this goal, finding ways to engage all county residents in taking part is significant.
The Cook County Community Solar Portal was made possible with support from the Searle Funds at The Chicago Community Trust. Elevate Energy developed the online resource in partnership with the Cook County Department of Environmental Control, the Environmental Law & Policy Center, and the Metropolitan Mayors Caucus. The community solar site is part of a larger effort to introduce and accelerate community solar installations in the region, a project supported by the U.S. Department of Energy’s SunShot Initiative.

Viewing sustainability within a timeline of the last 20 years, it’s clear that the idea has spread from individual idealism to a worldwide social movement. As shapers of the built environment, architects and designers have the ability to turn this momentum into something more systematic that can be integrated into workflows and become the new norm. Many, if not most, design firms feature leading-edge sustainable buildings within their portfolio.
However, aside from a handful of publicized buildings, much of the remainder of projects are designed at or near baseline building energy codes. In other words, most projects are equivalent to the minimum energy standards allowed by law. This “iceberg” phenomenon of unseen reality represents a major threat to a sustainable built environment. There are countless projects that aren’t front and center, and highly marketed. It’s difficult to quantify these projects in our portfolio that lie beneath the surface.

In cityscapes across the world, wood is slowly but surely making its way back. Architects in Australia, England and Norway have helped spark a global resurgence in wooden skyscrapers over the past few years. But while others have been quick to follow in their footsteps, American architects haven’t yet adopted this new trend.
