Program Goals

Program Results

Context

THE SITE

Site design planning such as minimizing disruption and preserving open space.

The concept

Final site plan

Ground level plan

Use of standard or modular dimensions to avoid cuts

Second level plan

Create roof decks over habitable spaces to avoid expensive timber deck construction

Minimize openings on the north side

Site mitigations and excavation – protecting against erosion and

minimizing disruption to the environment

Cut and fill

to avoid removal of soil from the site

Create a detailed framing plan and detailed material take-offs. Provide a onsite cut list for all framing and sheathing material

Use of Engineered Lumber, Precut Material Packages and to Avoid Waste

Insulation high density fiberglass behind 1” of closed cell spray foam to walls, closed cell to ribband and roof, open cell spray foam around all window openings, Closed cell to roof

Tight Envelope

Photovoltaic solar array

Vapor and thermal barriers

RAINWALL

Innovative materials

Recycled Finish materials

Low VOC cabinetry and finishes

Glass Balustrade

Healing the site

UPFRONT COSTS

vs.

LONG TERM OPERATIONS & COSTS

Consider Life-cycle costs:

A 2% increase in upfront costs due to the use of green

building products would result in life cycle costs of 20%

This is 10 times the original investment
