When should I flush out of a building be done?

Phased flush-outs require 3500 cubic feet of outdoor air per square foot of floor area to be flushed out prior to occupation, then continual ventilation (at 0.30 CFM per square foot) after occupancy until the expected 14,000 cubic feet of air is reached.

What is a flush out in construction?

A flush out is the process of forcing air through a building for a period of time before occupation to remove some of the pollutants that off-gas from newly installed components, fresh paint, materials, finishes, and furnishings.

What is a LEED requirement?

LEED Certification Minimum Requirements Be in compliance with environmental regulations and standards. Must meet the threshold of floor area requirements. Meet a minimum of building occupancy in terms of number of users. Maintain a reasonable site boundary. Be a permanent building.

Can you lose LEED certification?

A building can never lose its LEED certification achievement. You will always be able to say that the building was certified to the level achieved on a particular date. A project can continue to maintain up to date certification by being recertified – and demonstrate additional, important green achievements.

How is Legionella treated in water?

Other methods to control Legionella include copper and silver ionisation and biocide treatments (eg chlorine dioxide). To ensure that they remain effective their application will need suitable assessment as part of the overall water treatment programme including proper installation, maintenance and monitoring.

The five-minute flush

1. Hot water – a minimum of 50 degrees Celsius after one minute (55 degrees Celsius in healthcare settings). With a TMV fitted, water temperatures at the hot tap should not exceed 44 degrees Celsius.
2. Cold water – a maximum of 20 degrees Celsius or below after two minutes.

What do you need to flush a building for LEED?

LEED requires a building flush to be executed by supplying a total air volume of 14,000 cubic feet of outdoor air per square foot of floor area, all while maintaining an internal temperature 60° and relative humidity of 60%.

Which is better for LEED building flush out or IAQ?

While each construction project has unique characteristics that may influence whether building flush-out or IAQ testing is the best route, under Version 4 the scales are tipped in favor of IAQ testing. Under LEED v.4, IAQ testing earns a project two credits compared with only one from building flush-out.

How much air does a phased flush out need?

Phased flush-outs require 3500 cubic feet of outdoor air per square foot of floor area to be flushed out prior to occupation, then continual ventilation (at 0.30 CFM per square foot) after occupancy until the expected 14,000 cubic feet of air is reached.

What do you need to know about building flush out?

With building flush-out, essentially the building is purged with outdoor air and the assumption is made that IAQ is acceptable. This does not provide any measurable air quality data that can be used as a baseline or referenced by building managers in the future.
