LEED® for New Construction*
IEQ Credit 3.1: Construction IAQ Management Plan – During Construction
IEQ Credit 3.2: Construction IAQ Management Plan: Before Occupancy
The intent of these LEED credits is to implement an Indoor Air Quality (IAQ) Management Plan during the construction and pre-occupancy phases of the building that reduces indoor air quality problems and minimizes health issues for construction workers and future building occupants.
Not only can TEMP-AIR provide an IAQ solution, but we can provide much of the required documentation for these credits in our estimate and record air quality information during the phases of construction, greatly simplifying your efforts to comply with the LEED requirements.
Since 1965, TEMP-AIR has been America’s leading provider of temporary, portable heating, cooling, dehumidifying, and air filtration services. Our 50+ years of experience permit us to size and lay out each unique project for maximum effectiveness.
A TEMP-AIR estimate will include:
- Analysis of ventilation requirements to ensure compliance with OSHA regulations
- Analysis of heating, cooling, or dehumidifying requirements
- Analysis of moisture management and condensation precautions
- Equipment selection, sizing and placement during construction phases
- Fuel and power requirements
LEED IEQ Credit 3.1: Construction IAQ Management Plan: During Construction
This credit requires the development and implementation of an IAQ plan for the construction phase of the building. It entails meeting or exceeding the Sheet Metal and Air Conditioning Contractors National Association (SMACNA) IAQ Guidelines for Occupied Buildings Under Construction, Chapter 3; protecting materials from moisture damage; and installing MERV-8 filters if using permanently installed air handlers.
How TEMP-AIR can help:
In its potential technologies and strategies, the credit states, “If possible, avoid using permanently installed air handlers for temporary heating/cooling during construction.” Additionally, the SMACNA IAQ Guidelines include recommendations for the use of temporary HVAC to protect the permanent HVAC equipment from dust and odors. More specifically, SMACNA recommends that the construction space be ventilated using make-up air to replace exhausted air.**
The TEMP-AIR THP-Series of direct-fired make-up air heaters use 100% fresh air that is heated and then evenly distributed indoors. This drier, tempered air has the ability to absorb moisture and ventilate the fumes from the construction process. It provides lower relative humidity levels and dew point temperatures inside the building to prevent condensation and minimize the potential for mold.
LEED IEQ Credit 3.2: Construction IAQ Management Plan: Before Occupancy
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 contaminated 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.
How TEMP-AIR can help:
In many cases, a building flush out will not be necessary if TEMP-AIR equipment is used throughout the construction process. The TEMP-AIR THP Series of direct-fired, make-up air heaters is specifically designed to remove moisture and disperse the harmful fumes and gases from the space. When TEMP-AIR systems are used properly, the IAQ test should be passed with ease.
If a flush out is required, the TEMP-AIR THP-Series of direct-fired make-up air heaters can then be used to purge the contaminated air from the space. The equipment is installed outside the space, bringing in 100% outside, fresh air to ventilate the toxic fumes from the building.
Not All Temporary HVAC Equipment is the Same
There are many types of HVAC equipment, each with their own benefits and ideal applications. In fact, TEMP-AIR carries each one of the types of heating equipment listed below in their rental fleet.
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 during the construction process.
When combining the costs of rental, fuel, and labor along with its impact on the environment, TEMP-AIR THP-Series systems will be your most environmentally friendly, effective, and economical option.
