Site

Site conditions:
previously undeveloped land
Site description:

Site sits on an open clearing in a sloped pasture with the building slid into the side of the slope. The planted roof of the building picks up the landscape and recreates the lost vegetaded area on the roof. Very little hard and impermeable surfaces ensure a natural rainwater management on site (LEED sustainable site criteria) Landscape disturbance and erosion control as per Vermont Act 250.

Materials and Design Strategy

Materials:

LEED informed material choices with preference of regrowing materials (predominantly wood construction) and materials with high recycled content. Waste disposal and recycling in accordance with LEED requirements. Where possible insulation materials with low environmental footprint (cellulose). Low VOC materials and finishes for interior buildout.All wood materials FSC certified.

Special architectural measures:

The building is oriented towards the south and generates the majority of the heating energy needed through solar and internal gains with shading strategies for the summer. The building is slid into the side of a sloped pasture and continues the landscape on its vegetated roof. Built to passive house standards with a highly insulated envelope and great attention to details (airtightness) the building maintains a comfortable interior climate mainly though these passive measures.

LCA Description:

No direct life cycle analysis was done but as part of LEED design criteria the construction was done with high level of waterproofing and moisture control details to assure a good airtightness and a long lifespan of the building. The well insulating and wind and air tight but vapor open wall assemblies with an exterior metal rain screen will have a long life span.

Indoor Environment Description:
The interior climate is exceptionally comfortable as the super insulation of the envelope provides interior surface temperatures close to the ambient air temperature. The air in the building is continually refreshed through the heat recovery ventilation system which also filters the air of pollen and other pollutants. As part of the careful material selection low VOC paints and interior finishes were chosen. Due to the high quality windows not only warmth is maintained in the interior but also sound is attenuated creating a very quiet interior. The large windows for solar gains also provide a high level of natural light to the interiors.
