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.

RCI SoCal 17th Hawaii Winter Workshop: Insulated Metal Panels – Design and Construction Challenges

By Ami Case | | No Comments

Harold Louwerse, Building Science Consultant, will be presenting Insulated Metal Panels – Design and Construction Challenges: Tales from the field and how to improve your next design using IMP at this year’s annual RCI SoCal chapter Hawaii Winter Workshop in Honolulu.

Exterior insulated assemblies are growing in popularity and Insulated Metal Panels (IMP) are chosen by Owners, Architects and Engineers as an attractive, cost effective, all-in-one envelope solution (moisture barrier, air barrier, cladding and insulation) or simply as a cladding and insulation over a separate moisture barrier. Designing buildings with IMP’s pose many challenges. This includes how IMP’s interface with other building envelope assemblies as well as the installation challenges to achieve the desired airtight and thermally efficient building envelope. What is easily drawn on paper can pose some serious challenges in the field

The presentation will cover and provide the following:

  • An explanation behind the basic building science principles behind IMP systems on the market today.
  • The presenter will explore various types of projects these systems have been used on and a review of typical building envelope and architectural detailing for these IMP systems. A review of several details showing typical construction of IMP systems and installation methods including cut joints, interlocking shaped joints, and termination details.
  • A review of several common challenges of the system including structural backup tolerances and structural material selection (Steel Frame vs. Concrete vs. Steel Stud)
  • Explore the challenges of maintaining the system’s thermal performance at openings, base of wall and penetrations and we will explore what can be done to minimize the effects of thermal bridging through this assembly.
  • A review of several case studies and project challenges of using an IMP system. Attendees will gain valuable first-hand knowledge from the presenter on dealing with challenges and offer up solutions that can be implemented in the design stage so you do not have to deal with them in the field.
  • A review of common post construction problems, including impact damage and repair options and methods.

BUILDEX Calgary: Endurance of Good Design – A LEED Building after 10 Years

By Ami Case | | No Comments

Yichao Chen, Building Energy Consultant, and Kalum Galle, Senior Sustainability Specialist, will be jointly presenting Endurance of Good Design: A LEED Building after 10 Years at this year’s BUILDEX Calgary Conference. Their presentation will take place on Thursday, November 10th from 12 pm to 1 pm in Palomino D.

As one of the early LEED certified projects undertaken by the City of Calgary under the then newly implemented Sustainable Building Policy, the Crowfoot Library appears to have withstood the test of time.

After 15 years of continuous use, the library was the recipient of an extensive energy audit and facility condition assessment undertaken by Morrison Hershfield. Initially designed with the use of natural day lighting in mind, the building was performing 30% better than then 2004 ASHRAE standard at the time of design. With system upgrades over the operational years and various retrofits to satisfy user-group demands, this building still performs better than its non-LEED certified peers.

This presentation will break down the energy uses, analyze performance characteristics, and discuss past and future energy efficiency measures. Presenters will benchmark these results against similar building types to gain a better regional understanding of how LEED Certified buildings perform over time, highlighting what needs to be done to keep the initial capital investment effective over time.
