Looking Beyond LEED

Sustainable business practices become more routine as design firms ‘green up’ for the future

Looking Beyond LEED

Sustainability is not new in the business world. Recycling programs, car-pooling and attempts to reduce company waste have been around for decades. Many industry experts say that the real focus on sustainability began in the 1970s when an energy crisis similar to the current one blindsided American businesses and consumers.

Higher heating bills and long lines at gas stations forced the nation to look at the causes of reduced natural resources, not just the effects, says Cheryl Marks, Green Team leader at WHPacific Inc., an Alaska-based engineering and architectural firm with offices in Colorado.

Today, businesses see their energy costs skyrocketing and are searching for profitable solutions that will sustain them into the future, says Jim Bradburn, director of sustainability for The RMH Group, an engineering firm in Lakewood. “Sustainable business practices require us to review what we’re doing now and ask ourselves what we can be done better,” he says.

“In the construction industry, the focus on the causes of reduction has developed into an understanding that new construction needs to be sustainable,” adds Marks. “And it is our responsibility to make changes happen by creating awareness through management and employees alike.”

Watching the Three P’s The past decade of changes has evolved into having green practices managed by a sustainable coordinator, committee or team.

Bradburn believes the effort involves following the three P’s of the bottom line: people, planet and profits. “A business must be cognizant of how it treats its employees, the community, clients and other stakeholders; how it treats the Earth’s finite resources; and how these two contribute to the company’s overall financial prosperity,” he says.

Architecture, construction and engineering have answered the call of stakeholders and clients by creating innovative, green structures that set the standard for the future of sustainable construction. And though these structures cost, on average, 3% more to build than traditional buildings, the U.S. Green Building Council reports that they save 30 to 40% on utility costs through the life span of a building.

“In our industry, things that used to seem unthinkable now seem like good business ideas,” says Travis Beck, principal of Eco-Savvy Design and Landscapes in Denver. “The dialogue has definitely shifted from ‘if’ we as an industry should go green to ‘how.’”


Considering the Impact In 1987 the United Nations defined sustainable development in its “Brundtland Report” as “...development that meets the needs of the present without compromising the ability of future generations to meet their own needs.”

This has become the universal standard for defining sustainability in all its forms, and for many firms, it has also become the standard for creating green business practices.

“These practices are going well beyond an inner-office recycling program,” says Bradburn. “I think we all agree that designing high-performance, climate-adaptive projects cannot be done in a vacuum.”

The next step for the A/E/C industry is to integrate green practices into all aspects of a firm’s work.

“Businesses should be questioning the way they have been doing things and begin to understand the environmental impact of their decisions,” says David Schafer, a principal at OZ Architecture in Denver. “When they do this, they are likely to change the way they operate.”

OZ now has a Sustainable Design Team to oversee its green practices. “The committee was created because the firm recognized the need to be organized and focused in our efforts regarding both sustainable design and environmental responsibility,” Schafer says. “The committee is responsible for bringing sustainability to all aspects of our work, from reducing our carbon footprint to educating staff on design and the personal aspects of sustainability.”


A Culture of Sustainability The understanding that everything the industry does must be sustainable is partly why many firms have created a sustainability coordinator or committee.

“In our industry, the creation of a green project must begin at the earliest conceptual phase,” says Jeff Hall, sustainable coordinator at Gensler’s Denver office. “Sustainability is a basic principle that ties us into our culture.”

In 1988 Gensler designed the American headquarters for Epson America Inc., a global technology company based in Japan. Back then, it was the first large-scale office building to use under-floor air systems, an innovation that launched Gensler into more sustainable design practices. The firm’s founder, Arthur Gensler, assisted the USGBC as a board member in writing the LEED standards for commercial interiors.

“The leadership of the Gensler sustainability group is actively involved in education about sustainability, both inside the firm and to our peers and clients,” says Hall.

In 2003 Denver’s David Evans and Associates underwent a firm-wide effort to identify a core purpose: “to be stewards of the built and natural environment,” says Paul Horton, director of sustainability for the consulting and planning firm.

“After the core purpose was identified, it was clear that an individual was needed to organize this overall stewardship effort, with a major focus on the sustainability program,” he says. “A key responsibility for this person is to foster a culture of sustainability among all of our employees.”

For many firms, the culture of sustainability is now going beyond recycling programs and carpooling. It can be found in internal greening efforts for the buildings the firms are housed in as well as making green education accessible.

“I think a new element in this movement is management’s recognition of the benefits that coincide with working in green environments,” says Marks. “Lots of studies show a reduction in health costs and that natural lighting increases happiness.”


Practicing Practicality Previously, many firms understood the need to be stewards of the environment, but many people didn’t know how to do that on a practical level, Horton says.

“The industry is at a critical threshold where it needs to re-examine, and in some cases jettison, old working habits and assumptions and form new, more deeply collaborative relationships with stakeholders, including landholders, academic institutions and NGOs,” he adds.

Although the future financial viability of green construction is uncertain, the way firms do business will almost certainly be affected by the need for increased sustainability.

“I believe there will be a systematic change in the way buildings are designed due to the green movement and improvements in the available design tools,” says Bradburn.

He and his architectural counterparts believe the next step for building innovations will go beyond LEED certification into net-zero or even net-positive energy buildings becoming commonplace.

“LEED is not a trend, and the business market is changing,” says Hall. “If you aren’t on board with sustainability, you are behind. The technology is available, and practices are quickly leading us beyond LEED.”

Greening the American Home

Green is the color to consider when keeping up with the Jones’.
The growing popularity of sustainable design in today’s homes can be attributed to many things, the biggest being the money a homeowner saves in energy costs over the life of the building. With the crippling rise in oil and electricity costs—some 40% in the last decade—the growing interest is understandable.
“Green building is a way of looking at buildings that allows people to be more responsible with energy and natural resources,” says Eric Cory Freed, principal of organicARCHITECT of San Francisco, Calif. “Going green is usually the most logical and economical choice, whether you’re building or remodeling your home.”
Freed believes that in the near future, all buildings will be green buildings, either by preference or regulation. Traditional constructed buildings consume 40% of the world’s total energy, 25% of its wood harvest and 16% of its water.
“You are losing money on every green feature you don’t include,” says Freed. “Anytime you remodel you have the opportunity to save money in the operational costs of your home.”
Today, homeowners have lots of options when it comes to retrofitting their homes for sustainability, including extreme makeovers with energy-efficient everything to small, subtle steps like insulating water heaters and installing dual-flush toilets.
The best thing to insure your remodel is successful is to adequately plan for everything you want done. You need to consider all the factors, which include budget, resale value of your home, and return on the investment. You must also decide if you want to do the remodel yourself or hire professionals.
The end result of your remodel is up to you. But the choices you make now will bring a healthier environment for your family to live in and an updated home you can be proud of.


Seven Points of Interest:

• Not sure where to start?
Make a list of your biggest complaints about your current home. Examine things like outside noise pollution, problems with temperature and light availability; all of which can be addressed through green retrofits to your home.

• Water efficiency:
In the average home, the toilet accounts for approximately 30% of household water. Dual-flush water-saving toilets save money (about 20% on monthly water bills) and reduce sewer loads, while conserving water.

• USGBC
The United States Green Building Council is a valuable source for data on green building. This organization has recently developed a LEED for Homes program that gives developers, homebuilders and homeowners steps to achieve a sustainable home. For more information, go to www.usgbc.org.

• GreenHomeGuide.com
Targeted at homeowners, this Web site gives reviews and descriptions of green products by the professionals that use them. Provides good information for greening a kitchen or bathroom.

• Green Building Costs More Than Traditional Building
This is not 100% true. According to the USGBC green building will add approximately 1% to the upfront cost of building. For that small cost, you get energy efficiency and lower water bills.

• High-end Green Design
The purpose of a green home is to cut down on energy use, increase water efficiency, improve indoor air and use materials wisely. None of these things will affect the design of your home. There are many green options that can add to the look of your home, like bamboo flooring, recycled glass terrazzo and stylish energy-efficient appliances.

• Finding Rebates and Incentives
There are numerous financial opportunities and incentives for greening your home. Local stores like The Home Depot and government agencies like the U.S. Department of Energy offer grants and tax incentives for your project. For more information, contact your local public utility commission, building department and energy sources.

Exterior Restoration of Sage Building Complete

(as seen at www.colorado.construction.com)

When developer Evan Makovsky, of Shames-Makovsky Realty Co., started the renovation and restoration of Denver’s historic Sage Building, also known as the Fontius Building, he and the design team set a goal to complete the exterior renovation before the Democratic National Convention.

“With the tenacity of our project manager, Barry Gilbert, we met our goal,” said Makovsky.

To commemorate the completion of the exterior restoration and renovation, flags and bunting—reminiscent of the building’s original 1922 grand opening—now adorn the newly restored terra cotta facade along the 16th Street Mall. The reintroduction of this building back to the public realm has taken the commitment of Makovsky and the design team led by Denver architectural firm klipp, Milender White Construction Co. of Golden and the assistance of the city and county of Denver and the Downtown Denver Partnership.

The $13-million restoration project was financed in part by Colorado Housing and Finance Authority and First Bank. Before the restoration, the dilapidated building on the 16th Street Mall at Welton Street with windows that dominated the facade and the east side of the building had been boarded up for decades.

Its delicate terra cotta, now restored to its original white with gentle red and blue accents, had been blackened after years of absorbing carbon monoxide from downtown traffic. “It’s an exciting project to work on because it had been Denver’s biggest eyesore,” said Todd Piccone, project manager of the restoration for Milender White Construction Co. “It is rewarding to bring it back to its original beauty.”

Widely known as the “Fontius Building” for its former tenant, this once-neglected keystone building is viewed as a doorway to the redevelopment of the entire block and the 16th Street Mall, according to Makovsky.

“Its restoration has set precedence for innovative city decision-making processes and solutions in restoration and adaptive re-use and, in the process, has captured the interest and imagination of the business community and general public,” he added.The architects at klipp worked from the building’s original architectural drawings for the restoration of building’s exterior detailing, including restoration of the glazed terra cotta elements and reconstruction of the base of the building in terra cotta by local artist Barry Rose.

“It’s an arcane, lost art,” said Rose, who is one of only a handful of artisans in the country who still works terra cotta by hand. “It is gratifying to be part of preserving a piece of Denver’s history.”

In a precedence-setting solution that reconciled the competing interests of historic preservation and sustainability, the building’s original windows were replaced with energy-efficient, custom-designed windows that replicated the original design, including the reuse of the original window hardware by Grabill Inc. of Almont, Mich.

“We had drawings and the original hardware to work with, so we didn’t have to entirely reinvent the wheel,” said Greg Grabill. “At the same time, we had to create a modern way of doing things.”The building’s renovation also includes new exterior lighting, canopies, and the addition of skylights for daylighting for the primary tenant, Sage Hospitality Resources, which will occupy the second through fourth floors. American National Bank will occupy 4,500 sq ft on the ground floor on the 16th Street Mall.

Highway Fund Fix Could Remove Colorado From ‘Life Support’

(as seen in Talk of the Rockies on www.colorado.construction.com)

The nation’s highway industry won a small victory last week when the U.S. House of Representatives approved by a vote of 387-37 a measure that could infuse $8 billion into the Highway Trust Fund.

The measure would transfer money into the HTF from the general treasury and delay an anticipated revenue shortfall in the fund that could reduce federal highway aid for state infrastructure projects by approximately 34%, endangering construction jobs nationwide.

“This is a critical piece of legislation for every state in the nation,” says Tony Milo, executive director of the Colorado Contractors Association, which represents the interests of the state’s heavy/highway contractors. “It will, at the very least, help Colorado, because our transportation system is currently on life support.”

In response to a decline in traditional transportation funding sources, the Colorado Department of Transportation cut its general budget by $300 million for FY09; and if tax revenues continue to decline, the transportation department plans to cut an additional $200 million in 2011.

If the U.S. Senate approves the measure, monies transferred into the Highway Trust Fund could bring approximately $80 million to CDOT’s FY09 budget.
“The ‘fix’ will help us tremendously,” said CDOT CFO Heather Copp. “CDOT made significant cuts across the board, mostly in programs that consisted of design and construction projects—Colorado’s construction industry needs this.”

So far the measure is stalled in the Senate.

The transportation department’s cuts included a 50% decrease in its budget for the surface treatment program, planned at $80 million for FY09 and down from $163 million in 2008. Although it’s not known how the state’s Transportation Commission will distribute possible funds from the HTF fix, the approximately $80 million coming to Colorado will most likely go toward patching and repairing the state’s targeted deteriorating highways.

“Colorado is being impacted by two issues that are converging as part of a growing crisis: skyrocketing fuel prices resulting in higher transportation construction costs and declining funding for roadway improvements, resulting in deteriorating roadways and bridges,” said Tom Peterson, executive director of the Colorado Asphalt Paving Association.

The national HTF, created in 1956, relies on revenues from the federal gasoline tax of 18.4 cents per gal. (24.3 cents for diesel) – which has not increased since 1993, despite inflation and rapidly rising construction costs.

Much of the CDOT’s revenue comes from state and federal gas taxes, which have remained flat. Rising prices at the pump are encouraging people to drive less, leaving the state with declining gas tax revenues.

It is currently estimated that the HTF will run a shortfall of more than $3 billion next year unless it gets help from Congress. And, because highway money is paid out over a number of years, a shortfall in the $3 billion to $4 billion range would result in only about $27 billion available to state and local governments for new infrastructure projects in 2009.

The current highway act calls for federal aid of $41 billion for fiscal year 2009.
Mary Peters, secretary of transportation, said vehicle miles traveled on the nation’s roads fell by 3.7% in May from May 2007, making it the seventh consecutive month of year-to-year declines and further cutting proceeds from federal fuel taxes.

During the 2008 legislative session, many industry officials said that Colorado’s legislature failed to address the state’s crumbling road and bridge network—a network with 122 bridges declared structurally deficient, 40% of roads listed in poor condition and 20% of roads reaching the end of their surface life.
“Currently, CDOT is having trouble maintaining current conditions of Colorado’s roads,” said Copp. “[It’s] a problem that has further been exasperated by budget cuts. If the fix isn’t passed, it is very possible that the current condition of highways and bridges will worsen.”

70,000 Sq Yd of DIA Carpet Reclaimed

(As seen at www.colorado.construction.com)

When an existing airport needs new carpeting, there is a lot to consider. Not only do the contractors need government security clearance but materials need to be delivered to areas that are designed to be inaccessible; work periods are limited to between flights and during overnight hours; and the tools of the trade must be examined, approved and turned in to the TSA at the end of every shift.

These are the challenges that Denver-based ReSource Colorado Inc. is encountering as it replaces the carpeting in concourses A and C and parts of the main terminal building at Denver International Airport.

Installation and tear-out, conducted concurrently because of the nature of the job and airport passenger safety concerns, has completed in Concourse C, the main terminal and the mezzanine in Concourse A.

“This gets everything done that needed to be done before the convention,” said John Stanfield, president of ReSource Colorado. The project will undergo a planned installation hiatus during August for the Democratic National Convention but is expected to be complete in November. “The convention couldn’t come at a better time,” added Stanfield. “My guys have been working nights and long shifts, so this will give them a chance to catch up on rest and restore their bodies.”

The old carpet, approximately 70,000 sq yd, consists of two types that will all be reclaimed in some manner, according to the company. The material from Concourse C was manufactured by C&A, a Dalton, Ga.-based flooring company, which has engineered a reclamation program specifically for its product.

The carpet is collected in semi-trailers and shipped to the company’s Georgia facility. The material is processed and begins a second life as backing for new carpet. “C&A’s process has been an easy one to work with, they really do all the work once tear-out is complete,” said Stanfield.

The carpet from Concourse A and the terminal is a rubber-backed product. ReSource Colorado has contracted with a cement plant in Sugar Creek, Mo., where materials will be shipped and burned for fuel. Built in 2007, the $7-million facility was constructed specifically for this purpose and operates under specific guidelines.

“I was required to send samples of the carpet to the plant so that it could be cleared for acceptance,” said Stanfield. “The material was thoroughly tested according to their specification to be certain it would burn clean and not emit any potentially harmful pollutants.”

The flooring contractor has a crew of 30 for the DIA project, including supply truck drivers, measuring specialists, project managers and 24 full-time installers working two shifts around the clock to complete the project by November. Along with the schedule, the company has faced a number of added considerations not typical of everyday flooring projects.

“From an installer’s perspective, things like fingerprinting for security clearance and the logistics of working in a facility that is always very busy aren’t normal concerns,” said Stanfield. “None of my guys were certified to drive on an airport runway, but they are now.”

Each of the crew had to be formally fingerprinted and cleared by the Transportation Security Administration and issued a photo ID badge in order to work the airport. But TSA involvement did not stop there. The government agency conducts daily checks on installation tools like carpet knives and razors brought into the airport building. The number of sharp objects checked out by TSA is recorded onto a log, and tools must be checked back in at the end of each shift. The check-in and check-out numbers are required to match every day.

“I think the biggest thing we have learned during this process is the value of coordination, patience and sound project management skills,” said Tanner DeJonge, project manager for ReSource Colorado. “Coordination with airport management, government security, the mill and reclamation facility are key to this project’s timely success.”

Another challenge the ReSource crew has faced is the lack of freight elevators in parts of the airport facility. “We had to get creative in transporting 650- to 900-lb rolls of carpet up and down airport escalators,” said DeJonge. The entire project consists of 70,000 sq yd of Bentley broadloom carpet that will be installed from 12-ft rolls.

According to Starnet Worldwide Commercial Flooring Partnership, a national alliance of commercial flooring contractors, this is one of the largest carpet recovery projects performed by a member to date.

Skyrocketing Asphalt Costs Mean Uneven Lanes

(as appeared in Talk of the Rockies at www.colorado.construction.com)

With construction costs increasing and transportation funds in decline, news of a nationwide shortage of asphalt and its ingredients is that last thing the Colorado asphalt paving industry needed. As the price for oil continues to reach record highs, asphalt prices have skyrocketed in recent months and a shortage of liquid asphalt is aggravating the situation.

“Surging prices for diesel fuel, asphalt, steel and other materials are clobbering construction budgets,” said Ken Simonson, chief economist for the Associated General Contractors of America. “In the first two weeks of July, asphalt prices have jumped by 40% in several parts of the country.”

In Colorado, the asphalt shortage is affecting 34 Colorado Department of Transportation projects, said CDOT spokeswoman Stacey Stegman.Metro Denver alone has six projects at risk of delays, having their completion times extended or being partially paved. They include the resurfacing of Interstate 25 between Santa Fe Drive and West 6th Avenue, the repaving of Colorado Boulevard between Mexico and Alameda avenues and two major paving projects on East Colfax Avenue.

Scarcity of Ingredients
Asphalt has two ingredients—stone or gravel, and liquid asphalt, a tar-like binder made from petroleum. The binder is scraped from the bottom of the barrel after other petroleum-based products have been processed. The ingredients are mixed together to make hot-mix asphalt for paving roads.CDOT requires a chemical polymer be added to strengthen the pavement, especially in areas where traffic volumes are high.

A higher global demand for the polymer, especially from China and India, has decreased its availability, according to Oklahoma-based SemMaterials, one of the largest asphalt producers in the United States. The closing of two polymer facilities in Europe hasn’t helped the situation either.

The shortage of liquid asphalt can be attributed, in part, to oil refiners concentrating on producing more profitable finished products from crude oil, such as diesel fuel, said Tom Peterson, executive director of the Colorado Asphalt Pavement Association.

Refiners also are processing lighter crude petroleum, which produces less asphalt than heavy crude, he added.CAPA believes that supplies should begin to improve in the fall or winter. But summer paving projects may already be impacted. “(The industry) believes refiners will begin to run heavier crude streams, which will increase asphalt supply,” said Peterson. “Once the shift to heavier crude streams has been made, it will take 30 to 45 days before additional asphalt barrels reach the market.

“Supply of asphalt for the 2008 paving season is going to be short,” Peterson said.

Priorities
Currently, CDOT is considering four options for its summer paving projects: delay work until next year; extend some projects’ completion times until later this year; use a different paving material, including one without a polymer; or partially pave some roads until more asphalt can be purchased, said Stegman.

“Priority will be given to projects on more heavily traveled routes, areas with the most significant pavement damage or those in the middle of construction,” she said.The rising cost of asphalt has also forced CDOT to agree to use higher percentages of reclaimed asphalt pavement and allow its use in the top lift of paving. The joint decision was made by CDOT and the Colorado Contractors Association in a June 5 meeting. CDOT has previously allowed only 15% RAP in the top lift.“The RAP Task Force felt that there were enough controls in place, enough study data and enough experience with RAP that CDOT could increase the use to 20% in the top lift,” Stegman said.

Cost Confusion

(As printed in the July issue of Colorado Construction magazine)

Volatile materials costs challenge Colorado’s preconstruction experts

A collapse in the housing market and the subprime crisis, along with reports of a weakening dollar, all directly correlate to a rise in construction materials costs, both locally and nationally. But overshadowing all of these events is a seemingly daily increase in the cost of crude oil that impacts every segment of the construction industry, especially preconstruction.
These global and national events are leaving materials costs difficult to gauge and will continue to do so through 2008, according to several economic indicators.
Although Colorado’s economy has not yet shown the same signs of recession as other regions, the rising cost of oil must be factored into nearly all project planning, according to James Vigesaa, owner of BleekerVigesaa General Contractors in Brighton.
“Construction costs being volatile certainly makes preconstruction more difficult,” he says. “And in that process we must focus on the cost of oil based on the current cost per barrel. However, projections like the possibility of oil reaching $150 per barrel by mid-summer has made it increasingly difficult to create accurate formulas for upcoming projects.
“Colorado seems to be on the complete opposite spectrum when it comes to economic recession than the rest of the nation,” Vigesaa adds. “And, if we want to see a leveling out of materials costs in relation to oil costs, we just better cross our fingers that oil has peaked.”
Although construction costs remain volatile globally, Colorado’s materials costs have seemingly leveled out-for now. In Denver, research from industry consultant Rider Levett Bucknall shows the first quarter experienced cost escalation of 1.2%, almost identical to that for the same period in 2007.
“Though our research does provide evidence of the continued trend towards lower quarterly escalation rates in many U.S. markets, record high crude oil prices in the first quarter of 2008 have somewhat lessened the effect of the falling cost of many construction materials associated with residential projects,” says Peter Knowles, executive vice president of RLB.
As residential construction spending slows due to a collapsing housing market, the demand for materials for products like concrete and drywall should cause costs to decrease, he says.
In Colorado, highway construction costs are greatly affected by higher crude oil prices, worsening the Colorado Department of Transportation’s 20% planned cut in its construction program for fiscal year 2009-a problem shared by many state DOTs across the country.
“Colorado is being impacted by two issues converging as part of a growing crisis: skyrocketing fuel prices resulting in higher transportation construction costs and declining funding for roadway improvements,” says Tom Peterson, executive director of the Colorado Asphalt Pavement Association.
RBL predicted that a gradual decrease in 2008 construction volumes from the historically high levels of previous years is anticipated to offer some relief on materials prices; however, it forecasts that 2008 construction spending will be subject to continued increases in cost escalation in the coming quarters, despite the current lower rates compared to previous years.
