Schools Look at Energy Recovery Ventilators to Supplement HVAC Units 

	Faced with growing concerns about mold and high humidity inside school 
buildings, many school districts are utilizing energy recovery ventilators 
(ERVs) as add-ons to their HVAC systems.
In warm, humid weather, ERVs reduce the temperature and humidity of outside 
air before it reaches a school's air conditioning system. (In the winter, 
they can improve comfort levels by raising temperature and humidity of cold 
outside air.) ERVs bring in large quantities of fresh air, while recovering 
up to 80 percent of the energy in the stale air being exhausted from the 
building. Using ERV systems can simultaneously reduce the stress on an HVAC 
system, improve IAQ, reduce energy demand, and save money.
"There is no question that ERVs make sense in schools," said Brian 
Schaffler, vice president of Memphis-based Gorham Schaffler 
(www.gorhamschaffler.com), which specializes in application and service of 
HVAC equipment and building automation systems. "ERVs will save significant 
dollars in energy costs."
Greenheck, the largest ventilation system manufacturer in the United States 
(Indoor Environment Review, August 1999), has seen its ERV business 
skyrocket from 1996 when it introduced its first system. "It's a rapidly 
growing part of our business," said product manager Aaron Gotham. "I'd 
estimate that about half of the 1,000 ERV systems we have installed have 

been in schools. Overall, the ERV business is probably growing 15-20 
percent per year."

When ASHRAE (www.ashrae.org) Standard 62 was updated several years ago, a 
standard was added for ventilation for schools of 15 cubic foot per meter 
(cfm) of fresh, outside air for each child per classroom. "All of a sudden, 
engineers found that they had to design buildings to meet this standard," 
said Gotham. "The idea was that if you bring in enough air from the 
outside, you will purge out the VOCs, formaldehyde, dust, and other indoor 
air problems. At least it's a defense against lawsuits if you've followed 
ASHRAE standards."
However, engineers and architects quickly realized that merely bringing in 
outside air brought in too much humidity, which led to mold growth and 
widespread reports of sick-building syndrome. A new solution was sought. 
"Engineers have learned that ERVs are one of the best strategies around to 
meet this need," Gotham said.
"Most districts when building new schools or performing school renovations 
are including one type or another of ERV. They want to create an 
environment that's healthy for kids," said Keith Dunnavant, national sales 
manager for Des Champs Laboratories, Inc. (www.deschamps.com), a 
manufacturer of high-end ERV systems in Natural Bridge Station, Va. "We get 
inquiries from school districts that have had IAQ problems that they need 
to solve, but also from districts that are trying to be proactive about 

Contractors Should Stress Substantial Energy Savings

HVAC companies should emphasize to school planners that the improvement in 
energy efficiency can be substantial. Here's a typical example, according 
to Schaffler: "A school with 20 classrooms, 30 kids per classroom, would 
require 9,000 cfm outside air. In Memphis a typical ERV will take 
98-degree, 80-percent humidity air to about 82 degrees and 68 percent 
humidity, which is a delta enthalpy of 11.0. So, 9,000 cfm times 4.5 times 
11.0 equals 445,500 BTUs of heat, or 37.125 tons. This would equate to 
significant cost savings in the Memphis climate."
Looking at it another way, Gotham said that a traditional air conditioning 
system in an American school is designed for an intake of about 10 percent 
outside air, but those systems are commonly run at up to 35 percent outside 
air to meet the ASHRAE ventilation standard. "They can't do this for very 
long," he says. "So if you have an ERV that's 75 percent energy-efficient, 
it takes that 35 percent outside air intake and knocks it down to about 9 
percent, which the system is designed to handle."
A good rule of thumb, according to Gotham, is that east of about Oklahoma 
City (the more humid parts of the U.S.), each 1,000 cfm of air that moves 
through an ERV will reduce air conditioning load by three to four tons. For 
an engineer who's designing a building to be both healthy and efficient, 
that is a significant savings.

(Part II will focus on what schools are looking for from ERVs, and what 
payback periods can be achieved.  The full text of the story is in the June

Comment Deadline Approaches on Draft IAQ Report

By month's end, federal environmental officials hope to get a clearer 
picture of whether occupational safety and health researchers and advocates 
will embrace a new draft final report entitled, Healthy Buildings, Healthy 
People: A Vision for the 21st Century.

"I think that this is a comprehensive document, but we won't know that 
until we get some comments," Mary Smith of the U.S. Environmental 
Protection Agency's Indoor Environments Division, told IEBline (Indoor 
Environment Business, May 2000, p. 1). "We'll look at the comments, make 
changes to the report as appropriate, and then we'll use it as a 
[guideline] document that gives us a lot of good ideas about what we can do 
in the future as resources permit."

EPA's priorities, as defined by the document, will set the agency's agenda 
for the next 20-25 years. Companies looking to the future of 
federal-business partnerships, research support, public outreach, and 
regulation should be aware of the initiatives that EPA supports.

The division is seeking comments to the following questions posted on the 
website www.epa.gov/iaq/hbhp/index.html:

* Do the vision and goals capture the themes that are essential for 
improved indoor environments?
* Are there opportunities for improvement that remain unaddressed in the 
potential actions?
* Which potential actions are most critical for EPA to undertake, which can 
others implement, and which can you engage in?
* Are there scientific, technological, health, economic, or administrative 
issues that have yet to be addressed?

Smith added that feedback so far only has arisen in the form of "inquiries 
and chats," but she anticipates and encourages more comprehensive

CPSC Seeks Comments on Lead-in-Candles Issue

The U.S. Consumer Product Safety Commission (CPSC) is seeking comments on a 
petition that it ban candles and wicks sold for candle-making that contain 
lead (IEB, March 2000, p. 2).

Although lead exposure from leaded cores is not considered a major IAQ or 
health problem, what's frustrating to the IAQ community is the fact that 
it's resurfaced 20 years after U.S. manufacturers voluntarily stopped 
producing lead-core wicks. Evidence through surveys over the past year 
indicates that the offending wicks are all imported.
CPSC has received requests from the National Apartment Association, the 

National Multi Housing Council, and the environmental advocacy group Public 
Citizen to institute such a ban. The submissions argue that lead in candle 
wicks produces hazardous combustion materials when the candles are used, 
creating a lead poisoning hazard for occupants, particularly children. 
Public Citizen further proposed that CPSC recall the imported products.

For more information on the petition and submitting comments (docket No. HP 
00-3), call CPSC's Rochelle Hammond at (301) 504-0800, ext. 1502.
