CASE STUDY HOUSE NO. 8.1 Context Located on NW marine drive across from Jerico Beach, the site opens to the north. There is a large home to the west at a higher grade.
Climate Vancouver is an oceanic climate that is subject to high precipitation levels in fall, winter and spring and moderate seasonal drought in summer months. It receives little direct sunlight in winter with short days. High pressure systems in the summer provide long sunny days.
Topography Located at the base of a slope, the site rises 5 meters from north to south. The elevation change provides the opportunity to embed the house in the slope, using the retaining wall to minimize its footprint while capitalizing on views from each level.
Zoning The site is currently zoned for RS-1 development
Case Study House No. 8.1 The most famous of the 25 case study houses, the Eames House was the residence of Charles and Ray Eames. The house was designed by Charles Eames with fellow architect Eero Saarinen in 1945. The home was invisioned to be an elevated glass box canatlevering over the front yard. It was to be constructed of entirely “off the shelf” components from steel fabricator’s catalogs. When the parts arrived 3 years later the design had been revised by Ray and Charles to the subtler bar configuration that tucks into the slope of the site. The building is broken down into a 7’4” by 7’4” grid ... In moving the house to a site in Vancouver, we inted to futher explore the role materials and prefabrication offer both in plan and envelope flexibility. By reorganizing the studio and house we can address site specific issues such as light, weather and privacy, while substituting materials to further address new climatic and technological conditions. By introducing new materials, we can adapt the intial concept of the modular structure to a new context. The system provides a novel way to deal with issues such as solar gain, weather protection and lighting conditions by simply filling in the provided grid.
STRUCTUAL & EXPERIMENTAL MATERIAL SELECTION CrossLam - StructurLam
CASE STUDY HOUSE NO. 8.1

Cross Laminated Timber or CLT is the green choice for schools, health care facilities, public buildings, commercial buildings, and multifamily housing because of it’s cross-layered construction, reduced carbon footprint, and ready to assemble system. CrossLam by Structurlam is a state of the art solid cross laminated timber panel that is ideal for floor, wall, and roof systems making it the perfect structural solution.
SOLERA® + Lumira aerogel R5, R9, R18 SOLERA® + Lumira® aerogel is a daylighting strategy that dramatically improves thermal performance making an extraordinary product even better. The inclusion of Lumira® aerogel in daylighting systems virtually eliminates the historical trade-off of insulation vs. natural light by providing 3 to 6 times the thermal performance. The unique properties of SOLERA® + Lumira® aerogel enable: - superior thermal efficiency - significantly reduced transmitted noise - exceptional glare reduction - unmatched durability

Vapour Condensation Analysis Vancouver The wall assembly drawn was designed to address the following criteria. First that the interior surface should have exposed panels to express the structural material within the interior space. Second that the exterior cladding be a climatically responsible and local material. Finally, that the wall assembly has adequate thermal performance. The typical wall assembly is as follows. An exterior ship lapped cedar cladding, this material should be sealed and or treated. An optimal solution would be to char and seal the horizontal cedar cladding with oil. This promotes long term durability against weathering and rot. While providing a “green” and aesthetically pleasing solution. The cladding has a 19 mm air space behind it, provided by vertical cedar furring. Extruded Polystyrene (XPS) is attached to the outside of the Cross- Laminated Timber (CLT) panels and provides the surface for the furring to attach. The XPS provides the majority of the thermal resistance. Between the CLT is Spun Bonded Polyolefin (Tyvek). This protects the structural material from water penetration but allows vapour movement across the assembly.

The CLT panel, like concrete provides a significant thermal mass, however because of its thermal resistance, the building material feel warm to the touch. The inherent thickness of the CLT panels and the presence of the adhesives inside the system provide a natural air barrier. This air barrier system is reinforced by taping and sealing the ends of the CLT panels and EPDM seals at all joints. Therefore design of the wall focused on protecting the structure from vapour penetration and thermal resistance. The interior air temperature is set at 18°C with a relative humidity of 50%. This on the colder range of comfortable with a relatively typical humidity. The winter climate data for Vancouver shows an average exterior temperature 4.8°C at 90% relative humidity. The difference on the exterior of the envelope between the SVP and AVP is rather small. This is because of the lower temperatures. However because of the RSI value of the rigid insulation and the low vapour permeance the AVP does not increase by any significant factor. The summer average temperature in Vancouver is 18.2 ºC with an average relative humidity of 77%. The interior and exterior temperatures are only slightly different. The only noticeable difference is between the desired interior humidity level (50%) and the significantly higher average exterior humidity level (90%). However at a higher range of temperatures the risk of humidity reaching the dew point is very unlikely. CLT provides interesting opportunities for envelope design. Because of the inherent properties of wood, the existing moisture content and thermal mass, it operates as an excellent permeable material to control vapour movement pending on the glue content. Providing most of the Vapour Pressure Control (86.21%) This very simple assembly provides adequate resistance to water penetration, vapour and air movement, and thermal resistance in Vancouver.
