Figure 1. Two-Unit Model at Inverness Gardens (Astilbe Path)

This 2-unit model townhome was built by Miller Homes in September 2011. The house was part

of the 2011 Syracuse Parade of Homes. This model has 2-story units with a loft option. The left

side is the finished model unit while the right side was left unfinished to highlight the

construction and insulation details. The unfinished side was also open during Parade of Homes

to educate the public about the energy efficiency improvements available in these units. As part

of the re-design process we worked with the builder’s architect to revise the plans for the 2-story

unit with loft (1984 sq ft) that was built at this site. In addition, the efficiency improvements

were also included into the plans for the 1-story (1582 sq ft) unit and the 2-story without loft

(1841 sq ft).

The major energy efficiency improvements incorporated into these homes included the Superior

Walls precast foundation system with 2.5” of insulation in the basement as well as the exterior

walls with 2” of exterior foam and 2x6” with 24” OC framing. The wall cavities were filled with

BIBS blown fiberglass. The cathedral ceiling used blown fiberglass, closed cell spray foam, and

2” exterior rigid foam under the roof deck. Blown fiberglass was used in the attic.

The key construction details are summarized in the following section. Table 2 compares the

originally proposed improvements to the actual implemented features. Table 3 summarizes the

costs of the implemented improvements. During construction we worked with the contractor and

recommended additional measures that could be implemented to better adjust to constructability.

In many respects the final design was better than we originally proposed.

The cathedral ceiling with 2x12” with 24” OC framing has 2” exterior rigid foam beneath the

roof deck. In addition, 3” of closed cell spray foam and BIBS blown fiberglass were installed

from below as shown in Figure 2. The design called for the end walls at the gable ends to be

offset by 2” so the exterior foam was not required on the walls for the attic and garage. The

approach eliminated the expense of unnecessary foam board and still allowed the garage and

attic exterior sheathing to be flush with the exterior foam.

foam was installed under the entire basement floor.

Figure 4. Photos Showing Truss Design and Insulation Choices for Second Floor Walls Adjoining Attic Space.

The top two photos in Figure 4 show that the roof trusses were designed to leave space to install

2” rigid foam on the second floor to attic walls. Then the rigid foam was sealed with closed cell

foam shown in the bottom two photos. This completely sealed the second floor from the

unconditioned attic space.

maintain the conditioned envelope.

The photo in Figure 6 shows a common occurrence in stick framed, residential construction

inaccessible corners are created by the end studs on every corner wall. In this case a jack and

king stud on the left meets a stud on right to form a void that is difficult to insulate. The 2” of

exterior foam and sealing techniques used in the construction of this home reduced the impact of

these empty corners. However, the plans had called for a different stud corner arrangement, as

shown by the drawing on the right side of the Figure that was intended to eliminate this issue.

Mechanical Systems

The mechanical system is a Combi unit that uses a tankless water heater to provide both water

heating and space heating. Potable (domestic) hot water is piped to a hot water coil in the air

handler that also provides cooling to the house. In addition, the system also included a solar

water heating system with a 120 gallon tank. The 94% efficient Rheem RTGH-95DVN

condensing, direct vent, tankless unit is shown in Figure 7. The 2.5 ton Rheem air handler has a

cooling coil installed in the cabinet and a heating coil installed immediately downstream. The

system is shown schematically in Figure 8.

Figure 8. Schematic of DHW and Space Heating System (Monitoring Pts Shown as Red)

Ventilation is provided by a fresh air intake on the return side of the air handler. A damper is

installed on the intake duct which is controlled by the Honeywell controller. The controller

operates the AHU fan and damper fan to supply the desired amount of ventilation. The

controller was set to operate the fan and damper for 36 minutes out of every hour (60% of the

time) to provide ventilation to the home. When the AHU operated with damper open, the

measured ventilation flow was 86 cfm; therefore, the average ventilation across each hour was

52 cfm. The controller also closes the damper when heating and cooling operation are required

for more than 36 minutes of each hour to limit over ventilation. Figure 9 shows where damper

control is located in the fresh air intake duct in the basement. The bottom-left photo in Figure 9

also shows the electric ionizing air cleaner that was installed in the air handler return duct.

In this house the builder also provided ventilation in the garage. The continuous duty exhaust

fan operates at low speed but jumps to high speed when the garage door opens. This system was

intended to provide the ventilation of vehicle exhaust and maintains the garage under negative

pressure. In the winter of 2011, the negative pressure (-10 Pa) caused some moisture from under

the slab to condense on the lower portions of the garage wall and discolor the paint. The garage-

slab-to-foundation interface was sealed to eliminate this problem.

Energy Performance

The energy use and savings predicted by REM/Rate for this house is shown in Table 4. The

heating load for the house with the proposed improvements is 37% of the baseline design and the

final, as-built design is 50% that of the baseline design.

Inverness Gardens 2 Floor With Loft Design

The house was rated according to the Energy Star requirements. The HERS Index for the house

was 52 and the NY HERS Score was 89.6. Savings are primarily due to air tightness and added

insulation.

Thermal images, using a Fluke TiR3FT, were taken of the duplex on December 2, 2011, in the

morning before sunrise. The stud bays built into the Superior Wall panels are clearly visible

through the variation of heat transfer. Slightly more heat loss is evident at the inside corner of

the foundation wall (surface 14-15°F warmer).

For this home to comply with ASHRAE Standard 62.2 - 2010 Ventilation and Acceptable Indoor Air Quality in Low-RiseResidential Buildings, a minimum of 54 cfm of mechanical ventilation must be provided continuously, 24 hours per day. Alternatively, an intermittently operating mechanical ventilation system may be used if the ventilation rate is adjustedaccordingly. For example, a 108 cfm mechanical ventilation system would need to operate 12 hours per day, as long as thesystem operates to provide required average ventilation once each hour.

This home MEETS the requirements for the residential energy efficiency tax credits underSection 1332, Credit for Construction of New Energy Efficient Homes, of the Energy Policy Act of 2005.

As demonstrated above, this dwelling unit has a projected level of annual heating and cooling energy consumption that is at least 50% below theannual level of heating cooling energy consumption of a reference dwelling in the same climate zone, and the building envelope componentsimprovements alone account for at least 10% of those savings. The projected heating and cooling energy savings above have been calculated in themanner prescribed in Section 2.02 of Notice 2006-27 of the Internal Revenue Service. Field inspections of the dwelling unit performed by theundersigned eligible certifier during and after the completion of construction have confirmed that all features of the home affecting such heatingand cooling energy consumption comply with the design specifications provided to the undersigned certifier.
