Thomas Jefferson’s Monticello Mountaintop Project

Charlottesville, VA

Owner

Thomas Jefferson Foundation

Timeframe

2013 – Present

Size

20,000 SF historic complex on a 2,500-acre UNESCO World Heritage site

Cost

$35 million

MEP engineering for this historic property includes infrastructure planning, system upgrades, and design across the main house and support buildings, with a focus on preserving artifacts and maintaining the building’s historic character. The design incorporates custom zoned temperature and humidity controls, a geothermal-electric plant with ground-source heat pumps and heat recovery chillers, and building envelope improvements to reduce loads while supporting long-term sustainability. Additional work includes electrical and utility upgrades, coordinated phasing, and integration of new systems with existing infrastructure.

Project Goals

Since the summer of 2013, 2RW has been a proud participant in the Monticello Mountaintop Project, a multi-year effort to restore Monticello as Jefferson knew it and to tell the stories of the people—enslaved and free—who lived and worked on the 5,000-acre plantation. Working closely with the Thomas Jefferson Foundation and a team of architects, historic preservationists, conservators, and contractors, 2RW has been providing a wide range of mechanical, electrical, and plumbing (MEP) engineering design services for this project. Jefferson saw the earth as a common and intergenerational right, suggesting that he would support the sustainable efforts being made on the site today.

Services

2RW has been providing a range of infrastructure planning and MEP engineering services for this project, including:

  • Peer review of proposed underground HVAC vault designs
  • Thorough analysis of environmental conditions within the house and the artifacts contained within it to develop appropriate envelope improvements, HVAC systems, and building controls
  • A comprehensive building envelope plug-and-seal strategy to reduce heating and cooling load and corresponding HVAC system requirements
  • MEP design for updates to the main house, North Dependency, administrative offices, public restrooms, and support buildings
  • Design of custom, zoned temperature and humidity controls to preserve the house’s collections based on their type, historic value, and location
  • Design of a geothermal-electric plant with a 33-well ground-source heat pump (GSHP) system and dedicated heat recovery chillers (DHRCs)
  • Upgrades and replacements to site and building electrical, underground utility services, and generator
  • Coordination of utility work, geothermal well installation, and HVAC construction
  • Phased construction and parallel operation of existing and new systems during startup to allow for system optimization and a seamless transition

Results

The updated systems and new geothermal-electric plant:

  • Replaced outdated and inefficient heating, cooling, dehumidification, and ventilation systems with modern, energy-efficient systems appropriate to the building and its collections
  • Eliminated fossil fuel usage
  • Cut energy use and utility bills in half
  • Eliminated loud, inefficient, and unsightly oil-fired boilers, air-cooled chillers, and DX condensing units to preserve the quiet, contemplative environment that was the centerpiece of Jefferson’s “experiment”
  • Preserved the view shed by minimizing/hiding utilities and generators
  • Incorporated sustainable practices designed to meet the needs of current generations without compromising the needs of future generations
