"A Pattern Language from Passive House" is an interactive workshop that teaches cost-effective planning and design of affordable, low-emission, mid-rise, multi-unit, wood-framed housing.
This four-part workshop presents design problems common to multi-unit buildings, followed by solutions that have worked in previous high-performance projects. These solutions are organized into "patterns" using a format adapted from A Pattern Language by Christopher Alexander (et al).
This workshop has been designed to be a highly interactive online experience. Discussion is expected and participation in small-group design exercises (using online break-out groups) required. Each workshop will be followed by an "open floor" discussion.

Session 4/4: Affordable Mechanical
- Date: May 28, 2020
- Time: 12:00pm - 2:00pm
- Context: Heat-recovery ventilation primer; impact of flow rates.
- Tools: Unity efficiency vs. system efficiency.
- Patterns: Local - regional - central; tempered air; kitchens; sealed ducts.
- Case Studies: Centralized vs. ventilation risks.
- Intro: DHW is large demands; GWP of gas; GWP of refrigerants.
- Context: TEUI vs. PER; setting a budget as SD with PER calculator.
- Patterns: Short DHW runs, less DHW recirculation, pipe insulation; DHW heat pumps; elevators and pumps; appliances and plug loads.
- Small group exercise: Design mechanical spaces and select systems for a given building.
