Webinar Description

Achieving certification to Zero Carbon Building Standard or Passive House can seem like a daunting task, particularly on a retrofit project. The relative impact of thermal bridging and envelope transitions is amplified in low-energy buildings and particularly challenging to resolve in retrofit conditions. Humber College’s Deep Energy Retrofit Project for the Nx Building surmounted these challenges through careful integration across architectural design, energy modelling, envelope design, and mechanical design. Construction phase challenges were also met by implementing a robust testing protocol to facilitate EnerPhit and Zero Carbon Building certification. Retrofits are able to meet or exceed new building performance standards, illustrating that existing building stock can be an important aspect of reducing overall greenhouse gas (GHG) emissions due to the building industry.

Learning Objectives

  1. Understand what makes Passive House and Zero Carbon Building Standard certifications ideal for application at an institution and the challenges to be addressed to plan retrofit projects in particular.

  2. Evaluate possible energy conservation measures (ECMs) to identify the optimal package to suit a renovation project, with specific considerations and challenges involved in planning and delivering a high-performance.

  3. Put design concepts into construction practice and learn the challenges to be navigated to ensure intended building envelop performance via robust testing procedures.

  4. Find synergies across certifications with incremental improvements, looking at your high-performance project through a different lens, and understanding resultant load profiles.

Holly Jordan, B.Arch. Eng., M.Arch., OAA, EIT, LEED AP BD+C, MRAIC

Holly Jordan joined B+H in 2011 and has more than a decade of experience with commercial, institutional, and residential projects in Canada and the United States. Drawing on her professional degrees in both engineering and architecture, she is committed to finding innovative, sustainable approaches to all stages of design from early conceptual development through to final detail solutions. Her roles have included conceptual design development, site and environmental analysis, project management, consultant coordination, contract administration, and authority submissions. Building on her contributions to sustainable design, Holly served two terms on the Canada Green Building Council (CaGBC) Greater Toronto Chapter Board of Directors and continues on its Toronto-based Advocacy Committee. Her recent projects include the Humber College Building Nx, and H Deep Energy Retrofit Project, Manulife Centre Renovation, and Macdonald Block Redevelopment Project.

Steve Murray, P.Eng., PMP

Steve Murray has broad professional experience in condition assessment, investigation of building envelope failures, rehabilitation design, structural repair, construction documentation, contract administration, and facilities management planning. He has investigated, designed, and overseen repairs to dozens of buildings, involving roofing, cladding, masonry, curtain wall, EIFS, and windows. More recently, Steve has been active in providing architect and developer clients with envelope design assistance, design review, and energy optimization advice.

Rui Raposo, M.Arch., LEED Green Associate, PMP

Rui Raposo, project manager with Humber College, is an architect with expertise in building science. Rui is LEED Green Associate certified and holds a master’s degree from IST-Portugal in architecture. His research was based on retrofitting houses to more energy-efficient buildings, with special attention on operational and embodied carbon. He has over 12 years of practical experience with architecture in Canada, Portugal, and Brazil, working in vast programmatic areas as educational and commercial buildings, project management, and facilities management. Rui is currently focused on developing awareness on embodied carbon calculations for new and existing buildings going through renovations, and one of his goals is to turn Humber College into one of the most energy-efficient educational campuses in Canada with its Integrated Energy Master Plan (IEMP).

Alejandro Ortega, P.Eng.

Alejandro Ortega is a senior mechanical engineer at Morrison Hershfield. He has over 15 years of experience designing and evaluating mechanical systems for data centres, laboratories, central utilities plants, institutional facilities, transportation facilities, and hydro-power plants. His experience spans the entire gamut of engineering services, starting with master planning, pre-feasibility and feasibility studies through to detailed design, contract administration, and start-up and commissioning. Alejandro has been instrumental in implementing strategic building systems solutions to complement key building envelope improvement projects.
