Sustainable Lexington Committee Minutes of June 22, 2021 • The team identified that the tool could also assess the performance of Town buildings based on "Sustainability" factors such as energy efficiency, building materials, indoor air quality (air exchanges), etc. • S. Newall identify that Paul Brown (Gordian), who had to leave the meeting earlier, would be able to work with the Committee and provide a more complete description of how the"Sustainability" elements of the modeling would work. Several points to consider included: o The tool could consider materials, rooftop units (for air exchanges), etc. to be replaced beyond the standard system replacement. o The tool helps you work through the cascading number of changes that would be affected by the decision to change certain elements of a building. o The cost to add this assessment to the current modeling would be 5 to 6 cents per sq ft ($90,000)project to assess all buildings for sustainability; however: ■ Not all buildings would need to be considered: New buildings would not need to be assessed immediately because they have been built to the Integrated Building and Construction Policy, and old buildings (planned for replacement)would not need to be assessed.. • Q&A with committee members and guests included the following: o D. Voss: FCI is similar to PCI(Pavement Condition Index)being used by the Town. He would like to see how desired outcomes of our buildings (health, energy, emissions) are factored into the prioritization for capital improvement. o D. Voss: To do that, we need a performance policy so that we know how the buildings perform against those objectives and establish a performance index. He thinks of them as "high performance outcomes" not"sustainability" outcomes. We should prioritize this with the Town Manager. o C. Arens: Were there any surprises? ■ Facilities: We know what we spend so not too much of a surprise there, but it does help to prioritize what to work on first. Also, it identified that we're not spending as much on capital improvements as what the model suggests is needed. o C. Arens: How may people have access to the database? ■ Facilities: There are two levels of access. We can allow you to work in/view the database, but only a Facilities staff would have access to change data. o P. Chernick: How do you use the tool to decide whether to replace or upgrade? ■ Facilities: There's a lot of data in the tool and they are working to see how best to address that question. They have made similar decisions in the past(e.g., the 2.
