Lakeville energy committee recommends $17,900 Section 179D energy analysis for new fire station

The Town of Lakeville Energy Advisory Committee on Nov. 3 recommended that the fire station building committee hire Andelmann & Leek Engineering to perform an hourly energy simulation and Section 179D analysis for the new fire station design, at a fee of $17,900.

Magda, presenting for Andelmann & Leek Engineering, described an hourly simulation that predicts building energy use and energy cost for every hour of a year and compares the proposed design to a program baseline required under Section 179D. The modeler said the study will produce monthly and annual energy predictions, allow testing of "what‑if" design alternatives, help size future photovoltaic systems and provide a benchmark for commissioning and post‑occupancy tuning. Magda cited client examples in which models revealed discrepancies between predicted and actual bills and helped owners find operational savings.

Why it matters: Section 179D (the federal energy tax deduction for efficient commercial buildings) can reduce the net cost of a municipal building if the project qualifies. The committee noted the analysis also creates a predictable budget for facility energy use and provides a basis for commissioning to confirm the building operates as designed.

Committee discussion focused on whether the proposal should include TEDI (Thermal Energy Demand Intensity) calculations required by the Massachusetts Stretch Energy Code for group buildings and on small optional services such as LEED certification support. Magda explained that TEDI/TEDI calculations are separate from a full hour‑by‑hour 179D model: TEDI isolates envelope performance and is typically prepared by the project design team to comply with the stretch code, but the firm can provide TEDI as a peer review or optional service if the design team does not. The presenter said LEED support would be a small additional fee; TEDI is a different analysis packet and could carry a modest extra charge although no fixed add‑on price was given at the meeting.

Formal action: the committee moved and seconded a motion to recommend the proposal as presented (the base $17,900 scope) to the fire station building committee. The advisory motion passed unanimously with no abstentions. The Energy Advisory Committee does not have contracting authority; the recommendation will go to the building committee and then to the town for any contractual decisions.

Clarifying details gleaned at the meeting: the proposal includes five alternative simulations to compare against the Section 179D baseline; the presenter estimated Section 179D benefits could be on the order of "over $5 per square foot potentially" (accountant advice recommended for exact tax impact); TEDI is required for stretch‑code compliance but is often prepared under the architect's design contract; the fee in front of the committee covered only the 179D modeling and related analyses, not TEDI or LEED add‑ons.

Next steps: the advisory recommendation will be forwarded to the fire station building committee; the design team and building committee will decide whether to accept the recommendation and whether to procure optional TEDI or LEED services at an extra cost.

"We were asked to prepare a proposal for energy analysis for the new fire station with the main focus being on the so‑called 179D tax‑related analysis," Magda said during the presentation.

"We don't have the authority to enter into a contract, but just to recommend this to the building committee," the chair said before the committee vote.
