A statewide initiative: the expanding influence of Passive House in South Dakota

1 Prototype Governor’s House / income-qualified & pre-fab

2 CPHC sponsored training / professional community

3 Copper Pass / multifamily affordable housing

4 PH01:BRK / educating architecture students

While it isn’t an excuse, it is important to remember that design and construction in the region is entrenched in the known. There is little financial or cultural incentive for change or innovation.

from follow-up interviews:

Descriptions of projects that, for example, call for “a greater air-tightness or thermal envelope than usual, and then are changed ‘back to normal’ in the field” without knowledge of the architect are alarmingly common.

Other examples of municipal reviewers “waiving a nominal energy requirement for the financial benefit of developers and builders” seems standard.

A discussion of various contractor’s own interests and abilities ranged from excellent to unintelligible: one “questioned the entire topic of building science and the usefulness of knowing where the dew point falls in a wall assembly.”

3 Copper Pass pilot multifamily affordable housing, Sioux Falls SD


Copper Pass Affordable Housing Design & construction 2016-18 PHIUS+ pre-certification, 2017 (in-progress)

• SDHDA pilot Passive House affordable housing project • Architect: VanDeWalle Architects LLC • Developer: Costello Co. • General Contractor: BlackWing Elite Builders • Project Goals:

• Achieve Passive House certification • Build sister project to ENERGY STAR certification • Compare and analyze construction costs, operating

costs, and performance data of both projects • Originally 24 units; added 6 more when costs came in

under budget

Copper Pass Affordable Housing

Footing and Foundation Design

• Wanted to keep it conventional as possible

• Typical spread footing with 4’ foundation wall

• 3” of high density XPS under footing • Entire foundation wall wrapped with

3” of EPS • 4” of EPS under entire slab


Wall Assembly

• Typical 2x6 stud cavity • R-Max panels for

continuous insulation • Thin Brick & James Hardie

siding


Roof & Parapets

• Roof = R-75 • 24” roof trusses, blown full • SIPs above corridor • R-49 above roof sheathing • Boxed parapets outside air barrier • No ductwork in roof truss cavity

Mechanical System

• Energy Recovery Ventilator – zoned by floor. • Fresh Air Ducted to each bedroom. • Filtered Exhaust from kitchens. • Duct-free Mini-split System – one per apartment. • Condensing Dryers. • Low-flow plumbing Fixtures.

• challenges moving forward

1 Capitalize on the initial burst of activity and

keep the momentum.



2 Continued financial and political support from

the state is necessary…the expectation that the

construction industry will move towards higher

standards without incentive or regulation is

naïve.



3 The lack of serious building or energy code

implementation is a barrier…the ‘regulatory’

smell of codes is a cultural and political

obstacle that hinders the advancement of

building science.

It is the architect’s responsibility to raise

expectations, from both the state and the

construction industry.



4 The continued support of subsidized housing

must be maintained if not increased.


The investment by the state over the past four

years into Passive House is a remarkable legacy,

but one that still needs critical, positive

investment.

It is our hope that the exponential growth of

Passive House nationally will encourage South

Dakota to stay the course.

Thank you!
