The 8-foot deck/overhang on the left provides better summer shading than the 2-foot extended-width overhang, which performs better than the 2-foot window-width overhang, which performs better than the 2-foot vertical fin (late summer, 36N latitude)
Image
The 8-foot-deep west-facing overhang on the left provides much better shading late in the day than the 2-foot-deep overhang on the right (results shown for west-facing window, late summer, 36N latitude).
Image
The ability to choose a light color range allows one to customize the lighting of any space
Image
The AC unit has a drip pan and automatic shutoff in case the condensate drain gets clogged.
Image
The addition of low-E permanent exterior storm windows is typically accepted for most historic preservation projects
Image
The advance-framed 2x6 24-inch on-center walls are covered with netting then filled with R-23 blown fiberglass.
Image
Image
The air handler of the air-to-water heat pump is equipped with a very high efficiency air filter and a damper-controlled fresh air intake.
Image
The air intake or exhaust grilles in this second-story soffit will be very difficult to safely access to measure airflow
Image
The air tightness of the garage-to-house air barrier can be tested with a blower door kit and two manometers
Image
The air tightness of the house-garage air barrier can be tested using a CFM50 test that is first run with the garage door to outdoors closed
Image
The air tightness of the house-garage air barrier can be tested using a CFM50 test that is run first with the garage door to outdoors closed and then with the overhead garage door to outdoors open
Image
The airflow direction is labeled on the edge of the filter to ensure it is properly oriented when installed.
Image
The application of intumescent coating/protection layer protects this elevated floor system from below.
Image
The asymmetrical design of this home offers a large uninterrupted south-facing roof plane for solar photovoltaic and solar thermal panels.
Image
Image
The Attachments Energy Rating Council (AERC) uses this label to indicate certified low-E storm window products.
Image
The attic duct chase insulated and sealed to the attic floor with spray foam
Image
The attic is insulated along the underside of the roof deck with 8 inches of open-cell spray foam.
Image
The attic is sealed and insulated along the underside of the roof deck with 5.5 inches of polyurethane spray foam, providing conditioned space for the HVAC system.
Image
The attic knee walls were constructed from 2x6s and insulated with R-19 batt, backed with 1 inch of XPS foam board with taped joints to provide a solid air barrier over the insulated surfaces.
Image
The attic kneewall and the open floor cavities under kneewall are both sealed and insulated in one step with spray foam insulation
Image
The back dam of the window sill will force water out
Image
The back-draft damper on this exhaust fan is closed to prevent cross contamination
Image
The back-draft damper on this exhaust fan is open when the exhaust fan is operating
Image
The back-draft damper open when the fan is actively exhausting and closes when the fan is off
Image
Image
The base of the plywood parapet is air sealed with spray foam and fibrous insulation is installed in the rafter cavities in this flat roof retrofit
Image
The basement is constructed with precast concrete walls lined with R-21.3 foil-faced rigid foam while an R-10 layer of XPS rigid foam covers the ground under the slab.
Image
The basement is half in and half out of the ground with only 4 feet below grade, which allows for full 36-inch-tall windows that are completely above grade.
Image
The basement slab is wrapped in a blanket of insulation including R-27 of closed-cell spray foam under the slab and R-22 ICF blocks wrapping the slab edges.
Image
The basement walls are covered with a dimpled plastic water barrier then wrapped with 3 inches of XPS rigid foam with seams taped to keep out water.
Image
The basement walls’ interior framing is set in 3 inches from the concrete to allow space for closed-cell foam that is sprayed directly on the concrete, then blown cellulose is added to fill the wall cavity.
Image
The batt insulation shown here was properly installed to fill the ceiling cavities.
Image
The below-grade wall assembly includes dampproofing, draining details, and insulation.
Image
The black coating on these walls is a liquid-applied asphalt-based air and moisture barrier.
Image
The blocking for a new PV roof-mounting system is integrated with new rigid foam and the air and water control layers installed over an existing flat roof
Image
The blocking is completely flashed with roofing membrane before the PV rack hardware is attached on a flat roof
Image
The blower wheel (fan) on this ductless wall-mounted indoor unit has accumulated dust and mold - a common issue for this design.
Image
The blue foam sill gasket visible on the foundation wall will help ensure an air-tight connection with the double-wall assembly above.
Image
The board in the center of this photograph shows blue stain (not lumber mold), a discoloration of the wood caused by a fungus affecting the living tree, which did not harm the structural integrity of the wood.
Image
The brick house foundation piers on discrete footings (in the foreground) failed by rotating and overturning while the piers set in the concrete mat survived Hurricane Katrina.
Image
The brick veneer lacked adequate ties to keep the brick from peeling off the wall in an earthquake.
Image
The builder in this very cold climate installed three layers of unfaced mineral wool batt in the double wall with a code-required vapor barrier between the middle and inner layers of wall insulation that is taped to barriers in the ceiling and floor.
Image
The builder installed 1.5 inches of soy-based spray foam on the outside of the walls over the OSB sheathing, then kept a ¾ inch gap between the foam and the brick veneer siding to allow moisture vapor from the bricks to dissipate.
Image
The builder installed a rain screen product that provides an air gap and drainage plane between the coated OSB sheathing and the cladding; the fabric layer folded over the bottom edge forms an insect screen.
Image
The builder installed this OSB under the roof rafters and air sealed the seams with tape then added a dropped drywall ceiling to provide a service cavity for ducts and wiring, while minimizing holes into the attic.
Image
The builder laid down a 4-inch base of aggregate rock, then covered that with a plastic vapor barrier that is taped at all seams and around all penetrations before installing the rigid foam under-slab insulation.
Image
The builder leaves a half inch gap between the exterior and interior walls so drywall can be slid between the two.
Image
The builder staggers 2x4 studs on 2x6 top and bottom plates which provides gaps to fill in insulation around the framing for a continuous blanket of insulation.
