Sustainable Design Case Study, A House by Cathy Schwabe, AIA
Thursday, April 5, 2012
Small Firm Forum:
Four of the more innovative sustainable features of a new Green Point Rated Palo Alto residence will be presented on April 5th at the chapter office from 12:00pm to 1:30pm by the Architect Cathy Schwabe, AIA, Landscape Architect and Building Contractor.
An integrated and collaborative team approach for design and construction provided the framework to meet the clients’ near net zero green goals. The result is a high performing, energy efficient home which exceeds Title 24 requirements by 41% and has the carbon footprint of a house half its size.
The linked indoor and outdoor spaces, which result in gardens at all three levels (1st, 2nd and basement) provides the connection for three of the four topics: planted green wall, below grade gardens, and daylit basement; greywater irrigation and edible landscaping; living roof and master deck garden. The fourth topic is the automated heating, cooling and ventilation systems tied to air source heat pumps and solar water heating that combine radiant heating in the floors, radiant cooling in the ceilings, motorized windows, shades, a whole house fan, and heat recovery ventilators.
The presentation of each topic will include its relationship to the Green Point Rating system as well as a description of how the integrated team process was used.

1. Be able to identify strategies for daylighting basements through the use of below grade garden spaces and the components of a planted vertical green wall.
2. Understand the components of a greywater irrigation system, the structured plumbing fixtures that feed it and what it can and cannot be used to irrigate.
3. Understand key aspects of a living green roof that includes a trellis, both built-in and prefab planters, a wood deck, and outdoor tub and shower; and, they will be able to identify the components of the roof assembly that are required for waterproofing, plant growth and drainage.
4. Understand key aspects of an integrated and automated heating, cooling and ventilation system that includes radiant heating, radiant cooling, motorized windows and shades, a whole house fan and heat recovery ventilators with humidity sensors. The participants will also learn about the three energy sources that power these systems; air source heat pumps, roof mounted solar hot water panels and the current off site purchase of 100% green electricity while the house is pre-wired for future PV.
Note: The relevant connection to the Green Point Rating + Certification system and a description of how the integrated team process worked will be included in all four of these learning objectives.
