Option 2, Path 2: Stormwater Design—Quantity Control

In order to document compliance, you’ll need to enter all required data into the LEED Online credit form. The credit form will then generate the following valuable information.

You’ll get an itemized comparison of costs tracked during the LEED process with documented expenses for five years prior to LEED certification in terms of:

gross costs,
costs per square foot, 
and percentage of each spending category relative to the total operating expenses.

You’ll get an analysis of sustainability measures implemented in terms of:

You may be able to realize savings from this credit if you use the cost data and analysis to inform capital improvement decision-making.

It’s best for project teams to track financial data using tools and procedures that work for them and their accounting staff. There should not be a need to institute new tools or procedures. If looking for a tool to organize your data, consider using the Cost Analysis Tool (see Documentation Toolkit) to organize your data. This tool was provided under the previous version of LEED Online as a way to record all of the required data. It is still up to the task of tracking your information until you’re ready to enter it into the LEED Online credit form.

Establish a procedure for tracking and recording the operating costs of the project building during the performance period. You’ll also need to be able to describe the costs of any improvements made during the performance period that will affect ongoing operational costs.

Don’t try to prove anything! You can earn the credit even if your data shows that your sustainability efforts lost money. The intent is to better understand how sustainability efforts affect costs, so data accuracy and completeness is the only requirement.

Moving forward, you’ll also need to provide data for costs associated with sustainability improvements and LEED project costs incurred during the performance period. The overall goal is to assess how sustainability initiatives and technologies impact building operating costs over time. Any credit that incurs costs or savings throughout your entire LEED project must be represented in this performance period cost data.

Early on in your LEED certification process, consider pursuing this credit. It’s primarily an accounting exercise to collect historical financial data detailing year-to-year expenses in the following areas:

cleaning services;
building repair and maintenance;
utility bills; 
and roads and grounds maintenance.

Depending on the extent of the mold found, remediation techniques can be expensive. Preventive strategies of the ongoing IAQ management plan will reduce the likelihood of going to extreme measures to remove mold.
