Foam Free High Performance Building Enclosures

Foam Free High Performance Building Enclosures presents a clear and practical guide to achieving the highest levels of resilient and sustainable building enclosures while eliminating foam. The growing performance demands of air control, vapor control, thermal control, health and sustainability are examined. Foam insulation, dominant in today’s high-performance marketplace, is increasingly recognized as hindering many of these building performance goals. Practitioners are therefore wanting and finding new solutions that virtually eliminate foam and provide greater performance. This presentation is a careful look at how to do it.

Learning Objectives:

    1. define what qualities differentiate high-performance enclosures from typical construction and how those qualities are evolving.
    2. describe practitioner concerns of foam insulation hindering efforts to meet the evolving high-performance qualities.
    3. describe how a foam free enclosure can more robustly achieve the qualities of high-performance.
    4. describe practical methodologies practitioners can implement, to successfully produce a high-performance enclosure that is foam free.

High Performance Historic Masonry Retrofits

The goals of historic preservation and energy efficiency and comfort often seem in conflict, as higher insulation levels can pose new risks to these timeless structures.  Yet it need not be so.

This comprehensive presentation discusses strategies for minimizing the apparent conflict while allowing for the highest possible performance – ensuring that the integrity of the structure won’t be compromised, and making a more robust structure for the next 100 years: preservation and high-performance working together for a truly sustainable future.

The classic brick wall is un-insulated (R-6-ish) 3 wythe thick wall, prone to air infiltration. As many historic buildings fall under some form of aesthetic scrutiny often exterior insulation is prohibited.  Therefore the only option to make these buildings energy efficient is to insulate them on the interior. This presentation takes a close look at how to insulate these walls safely from the interior – considering moisture drive, bulk rain water issues and insulation materials – avoiding the dangers of freeze-thaw and mold.

Learning Objectives:

  1. Describe key attributes for high-performance enclosures and how historic masonry walls often fall short.
  2. Describe key threats to the long-term stability of historic masonry walls.
  3. Describe ways in which high-performance goals can make a historic masonry wall stronger or riskier.
  4. Outline key qualities, components, and strategies to optimize both energy efficiency and wall longevity.

Decentralized High Efficiency Ventilation

Decentralized High Efficiency Ventilation is a high performance alternative to centralized, ducted systems for whole house ventilation. As buildings are being renovated or built airtight to meet greater demands of low-energy, high-comfort, toward Passive House and similar buildings – they need to be properly ventilated. Often centralized systems are not ideal given equipment and ductwork space requirements. With a decentralized system, there is no ductwork and the units are mounted within the exterior wall assemblies – giving designers and building owners new options for achieving high-performance ventilation. This course examines the component options and design parameters for such a system.

Learning objectives:

  1. describe the difference between centralized and decentralized ventilation systems.
  2. describe essential qualities of high performance, high-efficiency heat recovery ventilation systems.
  3. calculate the decentralized system sizing and layout.
  4. describe essential installation parameters.

Intelligent Daylighting Webinar: Design Without Sacrificing Performance

Daylighting elements and architectural roof glass are striking, desirable building features that historically come at a high cost: leaks, energy loss, thermal discomfort, and condensation issues. Next generation glazing is addressing these issues and developing roof glass elements, hidden daylighting features, and aesthetically-focused window systems designed to be thermal-bridge-free, and suitable for high performance envelope needs. Fenestration of all kinds requires special attention, but is especially important in high performance buildings, where they are fulfilling more occupant needs. Potential for thermal bridging, overheating, cold air convective currents and air or water leaks can dampen or destroy the gains of free daylight and visual comfort. The designer’s challenge is to meet both the aesthetic and performance demands of the building envelope.

This presentation covers methodologies for selecting daylighting solutions, presents case studies of that apply concepts, and lays out design considerations that apply to commercial or residential, flat or pitched roof, curtain wall systems, historic preservation retrofits and more. Proper integration and design decisions result in roof daylighting that addresses energy, light, health, ventilation, comfort, and overall wellness of both occupants and the longevity of the building envelope.

Learning objectives: 

  1. Describe common problems with daylighting elements, from design to installation.
  2. Describe attributes necessary for daylighting in high performance enclosures.
  3. Describe the methods for analyzing daylighting elements for thermal performance, and energy balance.
  4. List key design considerations of daylighting elements in regard to health impacts (air, light, and condensation risk).

Make It Tight – Building Enclosure Airtightness Training

In this four hour comprehensive introduction to building airtightness and air sealing, attendees will gain detailed knowledge about:

1.) Why an air barrier is critical to high-performance construction – with an in-depth discussion of the supporting building science. From energy efficiency to health to prevention of moisture damage, the essential importance of airtightness is one of the best kept secrets in construction today and this session will unravel the myths and provide clear explanations.
2.) What is an air barrier and what are air barrier standards today – including a comprehensive look at the materials and components used in making air barriers. From sheathing, to membranes, caulking, tapes and gaskets, there is a growing array of products to choose from and we’ll discuss them all and how they can help hit the airtightness numbers you need and keep it that way.
3.) How to design an air barrier – uncovering the complete process and critical decisions needed to optimize chances for success. Should the air barrier be outboard or inboard; how are the walls connected to the roof; what design decisions will make airtightness easier to achieve or harder. How do the materials and components go together and how to describe it in a way that helps the contractor make the airtight system a reality on site.
4.) How to construct and test an air barrier – describing implementation of design with real world examples of both new build and retrofit construction. We’ll see what is working well and what is not for different construction types. Then look at the tools and methods for testing airtightness and delivering quality assurance.
