Canaveral National Seashore

Replace Apollo District HVAC Systems

PMIS 252315

Version: 2026-04-10

1 PARK INTRODUCTION

Canaveral National Seashore contains nearly 58,000 acres of barrier island, open lagoon, coastal hammock, pine flatwoods, and offshore waters. With 24 miles of pristine beach, it is prime habitat for many threatened and endangered species providing nesting beaches for several thousand protected marine turtles. Two thirds of the park is in Mosquito Lagoon. The lagoon is designated an estuary of national significance and an outstanding Florida waterway. It is one of the most diverse and productive estuaries in North America. The national seashore also contains cultural resources that reflect human history in the Florida peninsula from 2000 BC to early 20th century Florida settlement.

2 PROJECT OVERVIEW

Replace HVAC systems at four facilities with high-efficiency, corrosion-resistant systems suitable for coastal conditions.

Eldora State House (Historic) Schultz (Leeper) House (Historic) Fellers Research Facility Resource Management Facility

Contractor must provide all labor, materials, equipment, supervision, and incidentals for complete system installation. Contractor responsible for full system performance regardless of omissions. New units need to meet current energy requirements including current SEER2 rating as well as current A2L refrigerant. New units shall be Carrier, Trane, Lennox, or Daikin and shall be energy star rated as well as close to a 16 SEER2 unit as offered. The design, installation, and operation of the proposed HVAC system must comply with all applicable federal, state, county and municipal laws, ordinances, regulations, codes, standards, engineering guidelines, and the terms and conditions of this project, including, but not limited to:

International Building Code - IBC Florida Building Code – Mechanical Florida Energy Conservation Code ASHRAE Standard 62.1 – Ventilation for Acceptable Indoor Air Quality ASHRAE Standard 90.1 – Energy Standard for Buildings SMACNA Phenolic Duct Construction Standards National Electrical Code (NEC), where applicable NFPA Standards applicable to mechanical systems and building safety OSHA 29 CFR 1926 – Construction Standards

Upon completion of installation, the HVAC system shall undergo commissioning and test and balance to verify proper operation. This should include airflow verification, system balancing and equipment startup verification, control system calibration, and performance testing.

3 ELDORA ESTATE HOUSE

3.1 DESIGN CONSTRAINTS

Built in 1913, The Eldora State house is a 3,330 square foot historic structure with architectural and structural characteristics that limit major alterations to the building envelope and interior spaces. The HVAC system currently provides conditioned air for the first floor through an underfloor air distribution system connected to downflow air handling equipment. If the existing HVAC system type is changed significantly, it can have a huge impact on the existing finishes and aesthetics of the historic building. Maintaining the current appearance of the building is paramount in consideration of the new HVAC system.

Primary HVAC components include:

Downflow split system air handing unit for the first floor and a horizontal split system for the second floor

Single stage heat pump units Underfloor sheet metal supply air distribution system Attic mounted externally wrapped sheet metal ductwork for the second floor Floor-mounted supply diffusers

Due to the historic nature of the building, the replacement HVAC system must minimize structural and architectural impacts. Major duct routing modifications or structural penetrations are not recommended.

Preservation of historic architectural elements Avoidance of structural modifications Re-use of existing diffuser locations throughout the building
