Before Occupancy
The intent of this LEED
(Leadership in Energy and Environmental Design) Credit starts with the design
of, then implement of, an Indoor Air Quality (IAQ) Management Plan
Pre-Occupancy phase of a newly-constructed building with the goals of reducing
indoor air quality problems and minimizing any health issues of the building
occupants that may otherwise occur from the construction/reconstruction
process.
This credit requires the development and implementation of an IAQ plan for the pre-occupancy phase of the building. Specifically, it requires a flush out of the indoor air prior to or during early building occupancy until 14,000 cu. ft. of outdoor air per sq. ft. of floor area has been delivered to the space. Alternatively, the requirements for this LEED credit can be met if IAQ testing can prove that maximum concentrations of EPA listed air pollutants are not exceeded. Please visit www.iersos.com for this IAQ Air Testing.
Industrial Hygiene Services (I.H.S.) is Portland, Oregon's leading provider of temporary and portable air, heating, cooling, dehumidifying, and air filtration services. Our years of experience enable us to uniquely size and design each LEED Flush-Out project for cost-effectiveness.
Not only can I.H.S. provide this IAQ solution, but we can provide all of the required documentation for this credit in and record air quality information during the phases of the Flush-Out, greatly simplifying your efforts to comply with the LEED requirements.
I.H.S. specialty equipment guarantees lower relative humidity levels and dew point temperatures inside the building while the outside air is supplied to prevent condensation and minimize the potential for mold.
If a Flush-Out is required (IAQ air sampling is not cost-effective or available or desired) for the LEED credit, our make-up air handling units combined with our air exhaust units are configured to your unique building to provide the necessary 100% outside air volume. This equipment typically includes 3 different types of air handling units: heat, dehumidification, and high CFM air supply units. This Specialized Equipment is engineered to your building space, as well as to the seasonal outdoor site conditions.
There are many types of make-up air and air handling
equipment, each with their own benefits and ideal applications. Please see some
of these types of equipment listed below.
There are several factors to
consider when determining which type of equipment will have the least adverse
impact on the environment. Amongst these are equipment efficiency, carbon
monoxide emissions, types of fuel used, costs, and the ability to improve indoor
air quality.Contact : www.iersos.com/BuildingFlush-Out.htm
