Air Tightness in Buildings Half-Day Seminar: Air Leakage Control in Buildings

By Ami Case | | No Comments

Mark Lawton, Vice President, will present Air Leakage Control in Buildings: A Canadian History at this half-day seminar jointly presented by the Association of Professional Engineers and Geoscientists (APEG) of BC and the British Columbia Building Envelope Council (BCBEC).

Session Overview:

Control of air leakage in buildings has been an obsession of Canadian building science for about four decades. In the last decade, we are seeing regulators from other regions of the world come to the realization of how important air leakage control is for building durability and conservation of energy. As we are confronted with new standards for air leakage control, it is worth reminding ourselves of what we have learned on the journey from building science to building practice.

This half-day seminar will be taking a holistic look at air barriers and air leakage. First, we will look at the history of air barriers, and will review the science behind it and the significances and/or consequences of its introduction back in the late 70’s and early 80’s. We will then hear about the new City of Vancouver policy surrounding new building air tightness requirements, a policy that is somewhat mirrored in the BC Step Code. To complement this, we will also review lessons learned from the introduction of similar requirements in other jurisdictions, in particular the City of Seattle. We will conclude by looking at the whole building air leakage testing, including the setup and the equipment needed.

Building Lasting Change 2017: Building Envelope Strategies to Achieve Net Zero

By Ami Case | | No Comments

Mark Lucuik, Senior Sustainability Specialist, and Alex Blue, Building Energy Consultant, will present Building Envleope Strategies to Achieve Net Zero at this year’s Canadian Green Building Council (CaGBC) annual conference.

Course Overview:

Net Zero Buildings are often achieved by maximizing the benefits of passive technologies, such as the building envelope, but it is difficult to know how much to invest in these technologies relative to HVAC systems or power generation.  We will explore the impact and trade-offs between both common and innovative envelope variables under the assumption that a highly efficient HVAC system is employed.  We will use our innovative energy mapping tool to compare thousands of energy simulation runs for a high rise residential building in both Vancouver and Edmonton, enabling attendees to better understand how to best invest in their envelope to cost effectively achieve a net zero building.

CSI West & Northwest Bi-Region Conference: Science of Water

By Ami Case | | No Comments

Stéphane Hoffman, Senior Building Science Specialist and Vice President, will be presenting Science of Water at this year’s CSI West & Northwest Bi-Regional Conference. The session will take place at 10:30 a.m. on Day 2 of the three-day conference.

Session Overview

Through a series of case studies, we will explore how advances in hygrothermal modeling can be used to more accurately predict the performance of buildings and their enclosure systems.

From basic fluid dynamic simulations to quantify the rain flow down a facade system or complex roof geometry to more complex fluid dynamic studies of air flow within curtain wall shadow boxes, learn how new modeling techniques can help design teams answer performance questions in the design process.

Other case studies will look at how multiple modeling techniques can be used to model the complex interaction within systems such as the impact of rainwater draining through a podium assembly or assess structural and thermal performance simultaneously to assess the optimum cladding support system. A final case studies will demonstrate how graphical interfaces can be adapted to more easily present the findings of parametric studies involving multiple factors and assist the design team to make informed decisions early in the design process.

2017 SeaBEC Symposium: Passive House and Commercial Construction

By Ami Case | | No Comments

Medgar Marceau, Senior Building Science Engineer, will be presenting on Passive House standards, common in residential construction, and how they can be applied to commercial projects at the 2017 SeaBEC Symposium.

Course Overview:

The accelerating growth of Passive House across the US and Canada is leading a change in the building envelope industry across the Pacific Northwest. With Vancouver’s new mandate to meet the Passive House standard for all city-owned commercial buildings, and Seattle’s progressively stricter energy codes, it’s only natural that our industry will have new challenges to meet on the pathway of sustainability.

There is a large knowledge base of how to build durable residential buildings that meet the Passive House standard. However there are few examples of commercial buildings meeting Passive House. This presentation will help bridge the knowledge gap between residential and commercial construction. Basic principles of Passive House are high levels of insulation, no thermal bridging, an airtight building, very high-performance windows and doors, heat and moisture recovery ventilation, and optimizing solar heat gains. All of this while ensuring occupant comfort and durability are paramount. Achieving these objectives in Passive Commercial will require the same.

This presentation will discuss:

  • Acknowledging the challenges in translating Passive House to Passive Commercial
  • Solutions for minimizing thermal bridging in commercial construction
  • Solutions for an air-tight interior vapor retarder
  • Thermally efficient at-grade and below-grade transitions
  • Using 2-D and 3-D simulation tools to evaluate hygrothermal performance

SeaBEC Monthly Meeting: Building Envelope Commissioning and LEEDv4

By Ami Case | | No Comments

Learn how the updates to LEEDv4 affect Building Envelope Commissioning at the April SeaBEC (Building Enclosure Council) monthly meeting.

Steve Vinci, Senior Sustainability Consultant and Building Envelope Commissioning Practice Lead, will present on how the changes affect building performance going forward.

Course Overview:

The Commissioning process has historically attached itself to the active systems, leaving the primarily passive envelope systems undefined and unchecked.

However, due to the significant changes in City and State Energy Codes across the US addressing envelope design requirements to meet air leakage control and thermal performance targets, a new light has been directed at the importance of commissioning the passive systems.

The code changes are requiring designers and contractors to deliver higher performance of their buildings, especially from the building envelope.

Building Envelope Commissioning (BECx) is a topic that will enable designers to be prepared for the new changes being implemented in LEED v4, as well as stay current on how certain building envelope assemblies perform related to energy performance while ensuring long-term durability.

Commissioning the building envelope is quickly receiving greater recognition as a critical element in achieving optimal building performance.

Schedule:

5:00-5:30 PM: Networking/Refreshments
5:30-5:45 PM: SeaBEC Business & Announcements
5:45-7:00 PM: Speaker presentation

Attendance for monthly SeaBEC meetings is free to members. Non-members may attend for a $10 entrance fee.

By Ami Case | | No Comments

Over There: The Opportunity for Canada’s Glass Industry in a New Era of Free Trade with Europe will be presenting at this year’s Top Glass Conference and Expo.

Yvon Chiasson, Senior Building Science Specialist is part of this 3-person panel presentation.

The session will take place at 11 a.m., April 20th.

Session Overview:

The ground is shifting in international commerce. It is a time of great uncertainty, but potentially also a great opportunity.

Glass Canada editor, Patrick Flannery, and a panel of handpicked experts discuss the recently signed Canada-European Union Comprehensive Economic and Trade Agreement (CETA) and what it means for Canadian architectural glass fabricators and contractors looking for business in Europe.

Topics will include:

  • changes to trade and tariff regimes,
  • differences between North American and European glazing standards
  • reviews of the construction industry prospects overseas.

As doubts swirl about the future of trade with the U.S., barriers are coming down across the Atlantic.

Other Panelists include:

  • Riyaz Dattu, Osler, Hoskin & Harcourt LLP
  • Bruce Nichol, Dow Corning U.K.
