Fall 2013 5 Atlanta Rising to the Challenge

By Maria Quiñones, Southface

The Better Buildings Challenge (BBC), announced by President Obama in 2011, is designed to integrate efficiency practices into our buildings that can lead to benefits including cost savings, avoided emissions and a healthier economy. Through the BBC, the President is challenging CEOs, university presidents, state and local government leaders and others to voluntarily commit their organizations to reduce their energy consumption by at least 20 percent by 2020.

In November 2011, the City of Atlanta officially launched the Atlanta Better Buildings Challenge (ABBC), becoming one of the first cities to accept the national challenge. Atlanta took the challenge one step further by adding water into its program. The goal: 20 percent energy and water reduction by 2020. Growth “Meeting the challenges of the 21st century requires The Atlanta BBC is part of Mayor Kasim Reed’s plan the ingenuity and innovation of leaders from every to transform Atlanta into one of the nation’s top-tier sector of our society. And I thank you for your cities for sustainability. While the program started continued dedication to building America stronger.” with an initial goal of committing two million square feet of space in the downtown central business President Obama’s letter to BBC participants district, it has seen an unprecedented amount of interest on behalf of building owners all over Atlanta.

He gave a progress update on its sustainability action plan, branding the the national challenge, stating that more than 120 community as an EcoDistrict. This summer, organizations representing two billion square feet Buckhead committed half of its office market, are reducing energy consumption by an average which surpasses the commitment made by many of 2.5 percent annually, equivalent to about $58 other cities to the national program.

Fall 2013 9 The Case for Indoor Air Quality and Improved Productivity

By Henry Slack, Indoor Air Coordinator for US EPA Region 4 and Southface member since 1978

As par t of my job, I keep up with indoor air quality (IAQ) research. Here are three reports that may expand your current ideas on ventilation.

A review of 27 separate studies - a “meta- analysis” - shows health benefits from delivery of more outside air.

First, the meta-analysis. If a lot of studies agree, the odds increase that they are accurate. So, experts often check multiple studies to see if they agree.

In this case, a group of fourteen experts reviewed 27 papers on health effects and ventilation. They found that higher ventilation rates in offices are associated with reduced prevalence of Sick Building Syndrome symptoms (mostly respiratory). The effect goes up to about 25 liters per second per person, which is 50 cubic feet of outside air per minute (CFM). (Sundell et al, Indoor Air 2011: 21; 191-204)

The findings are consistent across multiple investigations and different epidemiologic designs for different populations, so it seems trustworthy. That level of 50 CFM is three to four times higher than the level the air-conditioning engineers (ASHRAE) recommend. In this case, the reviewers did NOT recommend any particular amount of outside air; that was not the purpose of this study. They also did not discuss using outside air when local air pollution is bad. So, if 27 studies agree that more ventilation makes us healthier, you might want more ventilation, but keep reading.

Carbon dioxide (CO2) levels may affect our ability to make decisions.

We all breathe out CO2. Typical levels have been viewed as harmless, although more

CO2 makes our blood more acidic. Outdoor air has around 400 parts per million

(PPM) CO2 right now. A well-ventilated office building may see levels go up to 1,000 PPM (or 0.1 percent) during the day as occupants breathe out. Buildings without ventilation may go much higher, and submarines and space capsules may be 10,000 PPM or more.

For several decades, psychologists have developed decision-making tests that have been found to correlate with leadership skills. The tests have been taken by thousands of people in hundreds of studies, so they’re considered reliable. Researchers put 22 subjects through validated decision-making tests in a special room, or environmental chamber. Same people, same room, same day, but the air

held different levels of carbon dioxide (CO2) each time: 600 PPM, 1,000 PPM, and

10 The Southface Journal of Sustainable Building 2,500 PPM. Tests were double-blind: neither the subjects nor the technicians giving the tests knew what CO2 levels were present. They even changed the order of the CO2 concentrations tested, so that the subject’s level of alertness would not be a factor. The results were striking! (see figure 1) The study revealed consistent downward trends in seven of the nine scales of decision- making. This is statistically significant and means that the odds are great that this decline in the ability to make decisions is real. (Satish, U., et al. Enviro Health Perspect 120: 1671-1677)

Not bad, huh? Plus, higher test scores are likely! (See Mendell,et Figure 1.

Indoor Air (DOI: 10.1111/ina.12042).)

Finally, Dr. William Fisk and others with Lawrence Berkeley Laboratory conducted reviews of papers on ventilation and productivity. Dr. Fisk found numerous studies that show people in buildings with more ventilation are more productive. How much more? Well, a little can go a long way. In one study of 40 buildings, doubling ventilation saved 1.6 sick days (worth $500) per worker. (Milton et al. (2000) Indoor Air)

Using numbers from several papers and extrapolating nationally, doubling ventilation throughout the country yields $37 billion wor th of productivity gains, for an energy cost of $130 million. Using economizers (devices which bring outside air into buildings when the weather is good) would save energy and increase our productivity by $33 billion. The new equipment would cost $28 million. (Fisk, Building and Environment, 2011)

Schools measure productivity differently than businesses. Various studies in IAQ publications show consistently that increased ventilation improves school work and test scores by 3-16 percent. Ventilation strategies at the Southface Eco Office include a raised floor For example, a study of every fifth-grade classroom in one U.S. plenum that provides conditioned air in proximity to the work spaces county found higher test scores in the classrooms with the most (previous page). The simple notion of having windows that open, as outside air (see figure 2)(and yes, the researchers corrected for in the photo above, is an easy alternative for ventilating, especially in many factors that also affect test scores).

Fall 2013 17 Georgia Sees the Value of Solar

Continued from page 8

Georgia Power’s Game Changer

In November 2012, Georgia Power announced its Advanced Solar Initiative (ASI) which will add 210 MW through 2015, including 90 MW of distributed generation. The purchase price for distributed solar will be 13 cents per kWh for a 20-year term. Utility scale projects will be handled through a request for proposal process where bids cannot exceed 12 cents per kWh. ASI is the largest voluntary solar initiative in the country and represents a big step ahead for Georgia’s growing solar industry.

Value of Solar

Now, the Georgia PSC has directed another quantum leap. The recent ruling added 525 MW to Georgia Power’s Integrated Resource Plan (IRP), including 100 MW of distributed generation. With this addition, Georgia Power should have 800 MW of solar by the end of 2016. While this is a dramatic increase, it will represent less than 1.5 percent of Georgia Power’s current retail sales.

In making the case for more solar during the 2013 IRP docket, Georgia’s solar industry introduced the concept of “value of solar” (VOS), drawing on the exper ience of Austin Energy, which currently pays a 12.8 cent per kWh VOS tariff. Testimony showed that traditional avoided cost methodology does not capture the true value that solar (particularly distributed generation) brings to the utility’s system. VOS was described as a “full avoided cost approach” that captures all of the benefits of distributed generation.

Georgia Power’s witnesses agreed with key points in this analysis and said they considered Austin Energy’s tariff in determining payments that will be made in the ASI program. They acknowledged that solar should receive proper value for the benefits it brings to the system, that this value exceeds the company’s system-wide avoided costs and that paying for solar at its true value would not put upward pressure on rates.

The appropriate calculation for VOS or solar avoided cost in Georgia remains an open question. Georgia will be a critical test case for whether the solar industry gets a fair deal as the VOS approach is examined around the country. The broad support for solar in Georgia, as well as the PSC’s decision to expand the state’s solar capacity, will hopefully encourage other southeastern states to follow suit and capitalize on the region’s abundant sunshine.
