Present Day

A careful integration of the historic facade, renewable energy, and stringent green building practices gave birth to The Campus Square Building in Midtown Harrisburg, Pa.  Campus Square is a landmark mixed-use facility in the community and plans to become the first LEED® Gold Core and Shell Building in Harrisburg, Pa.  This building is part of a major revitalization by the city which, in Midtown, has been spearheaded by GreenWorks Development.  Their plan is to build/renovate over 1 million square feet within the 10 block radius of Midtown and do it all in an environmentally responsible manner.

Anchoring the Green Building Design was forty-six (46) geothermal wells (located under the footprint of the building) and a 220 Panel Solar PV System (42 kW) on the roof.  The Energy Harvest Grant which will fund the Solar Equipment was the first stimulus dollars awarded in the state of Pa.  In addition to the ground source heat pumps and solar PV system, here are some of the various green aspects of Campus Square Building:  fly ash used in every yard of concrete, white roofing material, high efficiency glazing, completely automated building management system (Wireless ATC, Security, Lighting & Solar), regional materials, IAQ plan during construction, low VOC materials, high recycled content in the finishes, low flow water closets and waterless urinals.

From the early conceptual stages of the project, LEED was a priority.  With the Architect (Ganflec Architects), Construction Manager (Wohlsen Construction) and an MEP Design Build Team all working closely together through budgeting and design to come up with the ultimate balance of cost, green aspects, efficiency and quality.  The end result is a well thought out, socially and environmentally responsible project which will house the new Green Center of Central Pa and several other tenants.  Hopefully the students of the new Green Center will be able to learn first hand from the green building aspects of Campus Square and assist in the continual growth of the industry.

LEEDBlogger.com guest author William Sutton was named Wohlsen Construction Companies‘ Green Liason in 2008 and works day to day as a Project Manager on their LEED and Green Building Projects.  To date, he has worked on 6 LEED projects in various phases of construction and is working with several owners currently to determine and establish green building goals.  William is on several green building committees throughout Central Pa and also volunteers at local schools and colleges to give informative talks about Green and LEED.  Follow William on Twitter via @LEED_Resource.

Ontario, Canada-based Icynene has developed an expanding,  spray foam insulation and air barrier product derived from castor oil.  The product exceeds ASTM standards for bio-based materials, is 100% water-blown and insulates and seals in one step.

For those that don’t know, as I didn’t until I conducted some research, the castor plant is an incredibly sustainable  and non-toxic crop.  Castor beans don’t require irrigation (in normal conditions), do not need to be treated with pesticides or fungicides and yield more than twice the oil of soybeans by weight.  In addition to the oil’s other modern usage in beauty products, it has been used as an ingested folk remedy for at least 4,000 years.  Yes, 4,000 years - castor beans found in Egyptian tombs have been carbon dated.

An example of the Icynene product in action is the LEED Platinum Fifth Town Artisan Cheese factory (seen above) in Prince Edward County, Ontario.  Given the factory’s unique interior environmental conditions required to cultivate cheese, it was critically important to create a high R-value building envelope that maintains conditions in all seasons and prevents condensation and mold growth.   The Icynene product was additionally used in the interior walls to create a thermal and vapor barrier between the administrative/retail areas and the production areas.

Other features of owner, chef, and eco-entrepreneur Petra Cooper’s factory are a subterranean, earth-cooled cheese cave, a geothermal heating system and solar PV.  They targeted, but I couldn’t confirm, 13 out of 13 for SS (the 20 acre site is a natural habitat for deer, beaver and native bird) and achieved a large number of MR points with local materials, recycled content and landfill diversion.

And, it’s a pretty good looking cheese factory, right?

This video is brief walk-through of the huge, 300,000 square foot Fossil Ridge High School in Fort Collins Colorado.  It earned LEED for Schools Silver certification and utilizes over 70% recycled material, solar panels  and heavy daylighting.  The best part of the video is that is is primarily narrated by students of the school.

A great statistic in this video is that the estimated $100,000 in energy savings each year translates into 2 new teachers on staff.  Thinking back to my high school days, it seems that facilities have come a long, long way.

Please let us know of any other LEED for Schools projects that you would like us to share.

Quick and Easy LEED Calculators

Posted by: Andrew | Comments (0)

The most robust online calculators for LEED are within LEED Online, but here are a few ‘public access’ resources that you could consider pointing out to clients for research.

  • Concrete and aggregate supplier Holcim Ltd has a LEED calculator for ALL of the credits in every LEED rating system.  It’s not for reliance purposes, but a great interactive educational resource for those interested in LEED certification.
  • EcoScoreCard powers the environmental calculators for quite a few building material manufacturers.  Rather than list each site individually, you can visit this site and click to them all.  Excellent for MR reference.
  • Walkscore.com is great for estimating community connectivity within the SS division.  The limit is that it only has data for the 40 largest cities in the US but, come on, it’s free.

Are there any sites that you think are noteworthy, please share them.

The world’s political, economic and business leaders released a report this week calling for $515 billion in annual investments into the broader development and establishment of a clean energy infrastructure worldwide.  Leaders further encouraged the pursuit of aggressive energy efficiency programs to squeeze better performance out of legacy fuels in an effort that would reinforce the effectiveness of clean energy technologies. 

World Economic Forum - Green Investing 2009“As the cost of clean energy technologies decreases and policy support is put in place, the shape of the eventual energy system is emerging. But the investment demand is substantial,” the report said. “Despite the recent turmoil, the world’s financial markets are up to the financing challenge, but they will need continued action from the world’s policy-makers and leading corporations.”

The report’s authors, Max von Bismarck and Anuradha Gurung from the World Economic Forum, and Chris Greenwood and Michael Liebreich from New Energy Finance, further assert that “enormous investment in energy infrastructure is required to address the twin threats of energy insecurity and climate change. In light of the global financial crisis, it is crucial that every dollar is made to ‘multi-task’ to create a sustainable low-carbon economy.”

The report identifies a series of eight specific clean-energy sectors that are expected to drive the emergence of this new infrastructure: 

  • onshore wind
  • offshore wind
  • solar photovoltaic
  • solar thermal electricity generation
  • municipal solar waste-to-energy
  • sugar-based ethanol
  • cellulosic and next generation biofuels
  • geothermal power

Every year, business executives, economists, political leaders, global NGOs and various intellectuals gather in Davos, Switzerland at a cloister hosted by the Geneva-based World Economic Forum.  Their goal: tackling issues that improve people’s lives.  In the past, issues ranging from third-world health crises to trade relations with China and the developing world have carried the day.  This year, even in the midst of unprecedented economic chaos – or perhaps in large part because of it – the World Economic Forum (in partnership with London-based New Energy Finance) has placed green infrastructure investment at the heart of its dialogue.

Indeed, the performance of investments in these types of technologies can already be seen.  According to the report, clean energy investments increased from around $30 billion in 2004 to over $140 billion by 2008. The report shows that despite the economic disasters of 2008, an index of the world’s 90 leading clean energy companies had a five-year compounded annualized return of almost 10%. 

Notable for real estate investors and developers – as well as for LEED professionals – the report echos claims made throughout our business, namely that “buildings can be even made energy positive, meaning they produce more energy than they consume” through the adaptation of technologies such as “integrated solar PV (roof, facade, window), chromic glass, heat-exchangers/pumps, smart devices, and smarter architectural building designs.”  And, “in the residential sector, nearly 80% of the investment would be directed at just one area–installing more efficient heating and cooling systems in existing and new homes.”

The report also acknowledges that we need to start with the low-hanging fruit, where we can make immediate improvements to energy efficiency that create immediate energy savings and short-term payback on capital invested.  Specifically, the report says that the importance of energy efficiency “cannot be underestimated,” citing a McKinsey Global Institute study that estimates growth in energy demand could be cut in half by 2030 simply through such means. The greatest number of global efficiency opportunities lies in the industrial sector (49%), followed by residential (23%), transportation (15%) and commercial (13%).

And whether you support increased governmental regulation or not, the report contends that the only way for a concerted, coordinated effort to succeed is if governments become involved on a variety of levels and for a long period of time, to ensure these new tools are used. “Policy-makers should enforce energy efficiency standards. Utilities and energy-intensive industries will respond to carbon prices and other price signals, but many individuals and businesses will simply not do so,” the report says. “As a result, there will always be a role for regulation to mandate certain changes in behavior, such as appliance efficiency and standby power limits, corporate average fuel economy (CAFE) standards and building codes.”

Finally, it’s worth noting that a direct connection can be drawn from this report to the recent economic stimulus package that was passed in the United States, in which some very significant sums of money were committed to the transformation of federal buildings into energy efficient, high-performance facilities.  The report says, “With central, regional and local government accounting for 35% to 45% of economic activity in all of the world’s largest economies, public sector purchasing can be a powerful force.  Clean energy use should be mandated in public procurement, which would create guaranteed markets for leading innovators in transport, heat and electricity.”

Incorporating a light shelf into your building design is a great way to make progress on EA and EQ LEED credits.  Basically, a light shelf is an architectural element placed overhead that redirects light deeper into a building than it would otherwise travel, thus reducing the need for artificial light.

Interior vs. Exterior:  A light shelf can be placed on the interior or  exterior of a building or, ideally, extend on both sides of the window.  However, in some urban applications with zero lot line conditions the shelf can only be interior.  While this, to some extent, diminishes the benefits it certainly doesn’t negate them.  The real loss is not as much in the volume of reflected light into the space as much as it is in the glare reduction on the lower part of the window system.

Limitations: There are, however, some limitations.  A shelf generally should be placed on the south elevation to take advantage of maximum sunlight exposure.  If your building doesn’t have a southern exposure, the benefits can be significantly diminished, especially on a northern exposure.  Also, a relatively high ceiling height is required for optimum benefit.  Depending on the source, you’re looking at 9.5 to 10 feet.  Lastly, in a geography with a limited number of sunny days, the overall benefit is reduced.

The most valuable aspect of the light shelf is that it is a passive solar technology, requiring almost no maintenance and has zero moving parts.  As with any ‘green’ technology or design element, the simpler the solution and the less ongoing occupant interaction required, the better.

We’re often asked what government grants and incentives are available to a client when evaluating solar and wind installations.

Here are two websites where we start our research on the availability of these funds and programs:

The Database of State Incentives for Renewable Energy & Efficiency (DSIRE).  DSIRE is an easily searchable database of state-level incentives available to organizations and individuals.  This site has a solar focus,but wind programs are outlined, too.

The US Deparment of Energy’s Wind & Hydropower Technologies Program site, Wind Powering America.  In addition to federal, state and regional program outlines, there’s a great amount of educational and reference information on this site.

One shouldn’t, however, assume that the funds outlined on DSIRE (or any government website) are available.  In many instances, a set amount of funds are set aside for a particular program the funds may already have been spent or committed.

But, knowing the programs that are available gives you a reference point when starting your journey through the bureaucracy.
