Project SNAPSHOT
Project Name: Martin Luther University College Rebuild
Location: Waterloo, Ontario
Building Type: Institutional – Education
Project Type: Addition and Renovation
Size: 23,600 ft²/2,190 m²
Completion Year: July 2018 (started in May 2017)
Performance Target(s): modernize infrastructure to meet current and future program needs while preserving heritage and improving energy performance.
Project Overview
Martin Luther University College, the founding institution of Wilfrid Laurier University, undertook an ambitious rebuild project that reimagined its historic seminary building while preserving its architectural legacy. Originally founded in 1911, the institution needed modernized spaces to support contemporary learning and community use. Rather than demolishing and starting anew, the project salvaged and reused original key materials including limestone cladding and structural components (steel & concrete), creating a revitalized facility that honors its past while meeting modern standards for accessibility, energy performance, and institutional growth.
Project Strategy & Outcome
Design & Construction Strategies
Envelope & Insulation:
- Original limestone cladding was largely preserved in place, with insulation added to the interior side of the façade walls to improve thermal performance.
- In areas where the new addition met the existing structure, the cladding was carefully removed, restored, and reinstalled.
- All existing windows and doors were replaced with energy-efficient alternatives.
Systems (HVAC):
- Variable Refrigerant Flow (VRF) systems were incorporated into the design of the new space, decreasing the quantity of ductwork, allowing maximum ceiling height, increased comfort and energy efficiency.
Interior Loads & Controls:
- Lighting and electrical systems were upgraded for efficiency and flexibility in both educational and worship spaces, incorporating occupancy sensors, daylight dimming, and timers.
Materials & Embodied Carbon:
- A significant amount of original material—including concrete foundations, floor slabs, and structural steel—was retained and reused, reducing the embodied carbon impact associated with new materials.
Other Notable Strategies:
- Integration of spiritual, academic, and community spaces within a heritage-informed design.
- Creation of accessible pathways and entrances to ensure full inclusivity.
Performance Outcomes
Energy Use Intensity (EUI): 237 kWh/m² (2019) *
Thermal Energy Demand Intensity (TEDI): 129 kWh/m² (2019) *
Operational Greenhouse Gas Intensity (GHGI): 0.03 kg CO₂e/m² (2019) *
GHG Emissions Reduction (% or tCO₂e): 50% reduction compared to pre-retrofit baseline in 2016
Operating Cost Savings: Aggregated energy-related utility savings from 2017 to 2024 total $19,306, averaging $2,413 annually**
Notes on EUI, TEDI, GHGI*：
The featured values are based on the first full year of operation following project completion (2019), chosen to reflect stabilized post-retrofit performance prior to the COVID-19 disruptions (2020–2023).
Compared to the 2016 pre-retrofit baseline, the project achieved:
– 41% reduction in EUI
– 59% reduction in TEDI
– 50% reduction in GHGI
– 57% reduction in total GHG emissions
For reference, 2024 values (EUI at 266.15 kWh/m², TEDI at 138.19 kWh/m², GHGI at 0.03 kg CO₂e/m²) remain favorable, indicating sustained improvements well beyond the initial post-retrofit period.
Note on Cost Savings**:
While energy demand dropped significantly, utility cost savings have varied due to inflation, rising electricity and fuel prices, and structural charges such as carbon tax. As a result, financial savings were lower than energy performance alone might suggest.
