Pre-Conference Workshop Descriptions

DAY 1: OCT. 4TH, MORNING (9am- 1pm)

1-A: Lawrence Berkeley National Laboratory
Join leading scientists and researchers at LBNL for a guided tour to see where the ‘magic’ of energy efficiency research happens.  Tours will include the rotating Flexlab building, the windows testing lab and the new range hood and appliance test labs. A free shuttle up to the labs leaves from outside the Downtown Berkeley BART at 9am. This tour includes lunch with a spectacular view of the Bay Area. – LBNL Staff

DAY 1: OCT. 4TH, AFTERNOON (1pm – 5pm)

2-A: Cooling Workshop (with a focus on Heat Pumps)
This workshop provides an overview of cooling and dehumidification strategies for Passive House buildings. After initial considerations on the reduction of cooling energy demand, the main focus will be on the energy efficient and cost-effective supply and distribution of cooling in Passive House buildings in warm climates. – Tomas Mikeska

2-B: THERM – Intermediate & Advanced User Workshop
We’ll look at common Passive House Thermal Bridge calculation issues such as: model extents, boundary conditions, resources, rules (ISOs), estimating ‘hybrid’ assemblies, when it is allowed / not allowed, ground-to-foundation sill details, window installations, estimating Point TB (Chi) and briefly illustrate 3D thermal bridge software. Primarily we’ll use THERM to assess assembly durability and mold/condensation resistance (fRSI calcs and boundary condition differences). The training is designed for those who have some experience with PH calculations / design but are seeking to gain experience with the detailed PSI-Value simulation and calculation methods. Participants should have THERM and a laptop and be able to follow along in real time.  The training will include step-by-step slides so all participants should be able to follow along later through a PDF distributed as part of the training. – Ed May

2-C: Windows: Getting the Most out of an Expensive Component
Your windows are nice, but how’s your install? Windows are often big, heavy, fragile, and in high performance buildings, windows are the most expensive components. When you pay for all that performance, you also want to make sure windows are properly installed. It’s about your building enclosure: one wrong move and your exterior walls can also suffer expensive damage. Optimal window installs take into account vapor drive at different times of year, and take steps to super-insulate the window frames for the best thermal performance. In this workshop we look at window installations that are airtight and correctly flashed – and as a result will last the life of the building. A proper window install will bump up your building’s comfort and efficiency, while ensuring that your walls stay dry. With both presentation and hands-on mock-ups, the workshop aims to provide tools for simple and effective high-performance window installations. – Lucas Johnson

2-D: Big & Multi-family Buildings: Ventilation, Modeling & PHPP 
This course will explore topics specific to multi-family Passive House buildings. There will be a strong focus on how to model particular aspects in PHPP. Topics covered will include: Ventilation requirements and options, mixed use buildings, building certification options, defining the thermal envelope, occupancy, working with multiple PHPPs, TFA calculation, additional ventilation worksheet, lighting, sanitary pipes, cladding penetrations, 3D thermal bridges, curtain walls, kitchen and dryer exhaust, and parking garages. – Andrew Peel

2-E: PHPP: A Design Tool for Architects
A quick-start guide to using PHPP for architects new to Passive House and energy modeling. A how-to session on starting with a sketch design, entering it into PHPP and getting meaningful and useful results swiftly so that design options and iterations can be tested and the building performance implications explored in real time. – Elrond Burrell

DAY 2: OCT. 4TH, MORNING (8am-noon)

3-A: ILFI Net Positive Workshop: The Living Future Pathway
Brad Liljequist

3-B: Architect’s Passive House Crash Course: Designing with the PHPP
This workshop will help architects and designers become better intuitive Passive House designers. We’ll start with an overview of the PH design process, including siting, massing, envelope and systems design, with an emphasis on practical application and case studies. We’ll then have a group design exercise, modelling in real-time using a custom dashboard integrated with the PHPP (available free to participants) revealing both the essential variables (envelope-to-floor-area ratio, window-to-wall ratios, shading, R-values, etc) and summary graphical results of the site energy balance, the specific heat demand, and the Primary Energy-Renewable. Through quick iterations and expert commentary participants will gain a deeper understanding of the interplay of architectural design and energy consumption for Passive House projects.– Dylan Lamar, Tessa Smith, Skyler Swinford

3-C: Renewable Energy Systems on Passive Houses – How to model them for certification
Learn how solar thermal systems can help a passive house achieve the basic level of PHI certification, and how PV and other forms of renewable energy (RE) can help a Passive house project achieve higher levels of certification. Real world implications of renewable energy choices will be discussed, as well as how to correctly energy model RE systems in PHPP software and how to document their installation for your Passive House certification submittal. – Christina Snyder, Chris Petit

3-D1: (FULL DAY) Big Buildings – Lessons from New York and Vancouver
This full-day workshop will focus on lessons learned and challenges faced by the first generation of larger Passive House projects. Steven Winter Associates, Inc. and RDH Building Science are currently involved in a few dozen mid-size to larger projects. Projects covered will include dormitories, office space, high rise residential and mixed-use buildings and factories for both new and retrofit applications. In collaboration, SWA and RDH have identified a list of common frustrations and difficulties, including inconsistent product info, new wall types, challenges with meeting window comfort criteria in northern climates, overheating and cooling challenges, new use of outside tools, need for quality control plans for site inspection, code challenges, and — perhaps most of all — the need to talk about structures and expectations for project management. This session is intended for experienced PH professionals only. Basics will not be covered. Advanced topics covering HVAC design issues and advanced PHPP modeling will be covered on a project specific basis. Extensive audience participation is expected. – Lois Arena, Monte Paulsen

DAY 2: OCT. 5TH, AFTERNOON

4-A: Optimized Architecture: Design & Passive House – the Architects’ Prerogative
In this workshop we will explore the architectural process of incorporating passive house into the design method. The emphasis will be how to introduce Passive House into the iterative design flow at all scales of building by assessing obstacles and opportunities. Topics will include site planning, building plan (the building does not need just to be a “box”), details to consider in sections: building sections, plan sections, wall sections, window placement. Aligning the building massing with program using PHPP. Design techniques for dealing with super-thick walls, roofs, and floors. How simple and small mechanical systems make our jobs easier as architects. Integration of various rain-screen finishes and materials with Passive House design. Projects types considered including using EnerPHit when doing a large retrofit, small scale building design considerations to large scale optimization. First half: Summary of firm’s PH workflow. Case studies presentations. Details of certified projects. Second half design clinic: one-on-one or group format. – Andrew Michler, Ted Sheridan, Jonah Stanford, Elrond Burrell

4-B: The EnerPHit Path: PHPP, Economic Analysis & Phased Planning for Retrofits
This workshop is for anyone who wants to know how PHPP can help with planning and verification of deep retrofits. We will present PHPP‘s numerous features and capabilities for application to the building stock – before as well as after energy retrofit. We will also focus on the specifics of EnerPHit verification according to component quality or heating/ cooling demand. You will learn how the EnerPHit classes Plus or Premium can be achieved by complementing energy efficiency with renewable energy generation. – Jessica Grove-Smith

4-C: An Intro to Passive House for Practitioners and Policy Makers
A short and sweet overview of the Passive House pathway to Zero, for large and small, new and old buildings, with a look at the new PER framework for All Renewable Grid Energy – (Presenters TBC)
