How to Maximize the Health of a Building Through Retrofit and Restoration

Building restoration of the exterior cladding can maximize a structure’s health with improved sustainability and indoor environmental quality (IEQ). Building rehab can enhance sustainability and IEQ, and provide several significant environmental, occupant, and financial benefits.

Healthy, sustainable construction protects the environment by:

Saving energy

  • Building retrofit allows for addition of more energy-efficient products, like wall and cladding systems, windows, doors, etc.
  • Building rehabilitation reduces energy use that would be needed for demolition and new construction.
  • It allows for reuse of embodied energy in building systems and materials.

Recycling of building materials

  • Less need for new materials, saving natural resources
  • Minimizes construction and demolition debris, so reduces landfill waste
  • Restoration reduces hazardous material debris
  • Improves building durability

Sustainable design improves the durability and longevity of a rehab building, to preserve natural resources and lessen maintenance costs by promoting fire-, wind-, moisture-, and termite resistance, and save money through lower repair, maintenance, and replacement.

Healthy, sustainable buildings improve the IEQ by:

Enhancing Indoor Air Quality

  • Decreases moisture infiltration that can lead to unhealthy mold and mildew
  • Avoids materials with high volatile organic compounds (VOC) emissions that can cause eye, nose, and throat irritations, headaches, nausea, and damage to the central nervous system, kidney, and liver

Improving Comfort

  • Improves the comfort level of the occupants by stabilizing temperatures within the building

Economic Advantages of Retrofitting and Restoring

  • Increases real estate values
  • Allows for quick occupancy of existing usable space
  • Often costs less than new construction
  • Commercial building restoration that improves sustainability and IEQ can reduce employee sick days and improve their productivity.


Sto’s A.R.T. of reStore® Program

Successfully achieving all of these benefits typically requires the help of qualified and experienced building restoration services or building restoration companies that implement innovative solutions for the restoration of buildings and monuments, like Sto’s The A.R.T. of reStore® program. Our easy-to-apply, safe, durable, and non-toxic products can also maximize the health and energy efficiency of a building by creating a tight building envelope that limits air and moisture infiltration.

The Four Treatment Levels of Restoration

In 1966, following the National Historic Preservation Act (NHPA) passage, the Secretary of the Interior developed the Standards for the Treatment of Historic Properties to guide historic building preservation practice and design. Moreover, all grant-in-aid projects assisted through the National Historic Preservation Fund mandate the Standards for the Treatment of Historic Properties, as described in 36 CFR 68.

The Standards cover four treatment levels of restoration for historic properties: preservation, rehabilitation, restoration, and reconstruction. The treatment level depends on the property’s historical significance, proposed use, physical condition, and intended interpretation. All levels permit code-required work to make properties functional, including the sensitive and limited upgrading of plumbing, mechanical, and electrical systems.

1. Preservation

Preservation involves installing measures needed to sustain the materials, existing form, and integrity of a historic building. The work involves steps to protect and stabilize the structure, focusing on ongoing maintenance and repairs of historical components and materials rather than new construction and large-scale replacement. Preservation does not involve new exterior additions.

2. Rehabilitation

Rehabilitation comprises repairing, adding, and altering a historic structure while preserving those components or portions which contribute to its architectural, historical, or cultural values. Rehabilitation permits the replacement of deteriorated features; however, the replacements must match the old design, color, texture, and, if possible, materials.

3. Restoration

Restoration should accurately represent a building’s character, form, and components from a particular time. To accomplish this, a builder must first remove building components from other periods and then reconstruct the removed parts to match the restoration period. In addition, builders can replace deteriorated features with new components that match the original design, color texture, and, if possible, materials.

4. Reconstruction

Reconstruction includes designing and constructing a new structure to match the aesthetics or appearance of a building from a specific historical time.
