What is facadein construction?

A facade is the exterior face of a building, the assembly of cladding, glazing, and trim that encloses each wall elevation. In commercial estimating it is a scope envelope that bundles distinct wall systems (masonry, panel, storefront, curtain wall) priced by their own units. You take it off elevation by elevation, then split it by system.

The definition

Facade, explained.

Facade refers to a building's exterior vertical enclosure, treated by estimators as the sum of the wall systems on each elevation rather than a single material. A commercial facade usually mixes systems: brick or stone veneer, EIFS, metal panel, storefront and curtain wall glazing, and the flashing and trim that tie them together. You quantify facade as gross wall area in square feet per elevation, then subtract openings and split the net area by system because each system carries a very different unit cost. Storefront and curtain wall price per square foot of opening, while opaque cladding prices per square foot of wall and per linear foot of edge trim. Facade scope also pulls in air and water barriers behind the cladding, sealant joints, parapet caps, and coordination with structural backup. The estimator's job is to make sure the elevations add up to the whole building, that openings are accounted for once, and that the system split matches the architect's exterior material legend.

How it is measured

Facade is measured in square feet of gross wall area per elevation, taken from the exterior elevation drawings, then netted for openings using the door and window schedules. Read each elevation, multiply width by floor-to-parapet height, and total all four (or more) faces for gross area. Pull the exterior material legend or finish legend to assign each region to a system: veneer, EIFS, metal panel, storefront, or curtain wall. Measure opaque cladding per square foot, glazing per square foot of opening, and edge conditions (parapet cap, base, control joints) per linear foot. Confirm heights against the wall sections and building section so parapet and spandrel zones are included.

Worked example

A worked facade example.

Worked example

Take a 4-story building, 120 ft by 80 ft in plan, with a 52 ft floor-to-parapet height. Perimeter is (120 + 80) x 2 = 400 ft. Gross facade area is 400 ft x 52 ft = 20,800 sf. The exterior legend splits the elevations: 40 percent brick veneer, 45 percent metal panel, 15 percent storefront and curtain wall glazing. Brick veneer is 20,800 x 0.40 = 8,320 sf. Metal panel is 20,800 x 0.45 = 9,360 sf. Glazing is 20,800 x 0.15 = 3,120 sf. The three add back to 8,320 + 9,360 + 3,120 = 20,800 sf, confirming the split closes to the gross. From here each system carries its own unit price (illustrative, US market), so the estimator prices 8,320 sf of veneer, 9,360 sf of panel, and 3,120 sf of glazing separately rather than against one blended rate.

Facade: frequently asked questions

Is facade one line item or several?+

Several. A commercial facade is a scope envelope. You break it into the actual wall systems (veneer, panel, EIFS, storefront, curtain wall) because each prices on a different unit and trade.

Do I use gross or net wall area for facade?+

Take gross area per elevation first, then net out openings from the door and window schedules. Opaque cladding is priced on net wall area; glazing is priced on the opening area you deducted.

Where do parapets and spandrels fit in facade area?+

Measure facade to the top of parapet using the wall and building sections, not just floor-to-floor. Parapet and spandrel zones are real cladding area and are easy to miss off plan elevations alone.
