Barren County Schools

Client/Owner: Barren County Board of Education (Glasgow, KY)

Project Team: WBW Engineering (Engineer), Venture Contracting (GC), Green Mechanical (Mechanical), Innerspace (Controls)

For Barren County Schools’ 2011 round of facility improvements, our team supported multiple building scopes—from a new ROTC building and a band room ventilation package to a storage addition—by assembling a coordinated HVAC equipment solution that balanced zoning flexibility, energy‑minded ventilation, and commissioning readiness.

What We Delivered (Highlights)

1) Barren County High School — New ROTC Building

• (2) AAON packaged rooftop heat pumps featuring R‑410A, modulating heat pump staging, and auxiliary electric heat capability.

• Controls/sequence support for VAV/CV operation

• Included configuration elements such as hot gas reheat, pleated filtration, and cabinet construction options (double wall insulation and stainless drain pan) as specified in the equipment package.

2) VRV Heat‑Recovery Zoning (Daikin VRV)

• A Daikin VRV heat‑recovery system anchored by a heat‑recovery VRV outdoor unit and branch selector units, paired with a mix of ceiling cassette indoor units to support room‑by‑room zoning.

• Controls infrastructure supporting multi‑group management and integration, including listed controllers and a BACnet interface.

• Practical installation coordination notes and responsibilities were clearly delineated (e.g., contractor‑provided field piping/insulation and refrigerant).

  
  

3) Ventilation / Energy Recovery

• Venmar energy recovery ventilator (ERV) included to strengthen outdoor‑air strategy and improve ventilation effectiveness for occupied spaces.

4) Barren County High School — Band Room (Outdoor Air Units)

• AAON packaged outdoor air units (tags OAU‑1, OAU‑2) configured for 100% outside air with modulating hot gas reheat, EC motors, and stainless steel heat section components as listed.

• A controls feature set oriented around stable supply‑air delivery and protection (e.g., phase/brownout protection and sensor set noted).

5) Hillcrest Annex — Storage Room Addition

• (2) Reznor gas‑fired unit heaters with key accessories .

Our Role & Value

Equipment package development & coordination: We translated basis‑of‑design requirements into a cohesive equipment schedule across multiple building scopes—packaged RTUs/DOAS components, VRV heat‑recovery zoning, and unit heating—while aligning stakeholders (engineer, GC, mechanical, and controls) around clearly defined inclusions/exclusions.

System Features (Why This Approach Worked)

• Zoned comfort with heat recovery: VRV heat‑recovery architecture and distributed indoor units are well suited to varied occupancy patterns and room loads across school facilities.

• Ventilation-forward design: Dedicated outdoor‑air strategies (AAON OA units and an ERV) help schools maintain indoor air quality while managing humidity and comfort.

• Packaged simplicity + advanced control: Rooftop packaged units combined with VAV/CV control intent and integrated sensor options supported practical installation with modern control expectations.
