Construction

Ensure that CO₂ sensors and outdoor air monitors, and installation costs are incorporated into the detailed budget from the bid documents through final contracts. CO₂ sensors are not common, and although the mechanical engineer is responsible for accounting for them on drawings, they could be a forgotten detail.

Integrating an automated BMS requires a highly skilled construction team. The BMS is a complex tool requiring skilled personnel who understand the controls and settings as applicable to the project.

The commissioning plan should include HVAC, monitoring, and alarm systems, with the appropriate sampling rate.

Verify that CO₂ sensors are 3–6 feet off the floor.

Contractor installs the monitoring devices as recommended by product manufacturer and mechanical engineer. Verify that all alarms have set points complying with ASHRAE 62.1-2007.

Compacted soil from high vehicle traffic prior to or during construction can severely limit natural infiltration of stormwater. Avoid site compaction during construction as much as possible (This also helps compliance with SSc5.1).

Commission any water reuse systems to ensure that they operate as designed.

Daylight sensors and other daylight controls should be added to commissioned systems for lighting for EAp1: Fundamental Commissioning.

Measuring daylight levels can be a time-consuming process in large buildings. Measurements are taken on a 10-foot by 10-foot grid, with four measurement points for each 10 ft² section. Taking and recording each measurement takes about 30 seconds—not including setting up the grid—for a total of about two minutes per grid section.

For Option 3, take daylight measurements with a hand-held light meter and record the values on a 10x10 grid plan. Enter square footage for the portions of the regularly occupied areas that meet the daylight requirement in the LEED credit form and upload all required documents to LEED Online.
