2, 3, and 4-Bedroom Modular Housing

Baker Lake, Igloolik, Clyde River, Taloyoak, Nunavut – 2024/2025/2026

​

Delta-T Designs Inc. was responsible for the complete plumbing system design for fifteen (15) modular 2-, 3-, and 4-bedroom housing units constructed for the communities of Baker Lake, Igloolik, Clyde River, and Taloyoak, NU. The scope included domestic hot and cold water systems, drainage, waste, and vent (DWV) systems, potable water storage tanks, sewage holding tanks, fixture layouts, and equipment selection.

As the project team member with specialized northern and remote-community design experience, Delta-T Designs provided technical guidance to the architectural, HVAC, and electrical disciplines on challenges unique to Nunavut communities. These included infrastructure limitations, sealift-dependent logistics, and operational considerations informed by local cultural practices. The designs emphasized system resiliency, redundancy, and long-term maintainability, with particular attention to inspection access, freeze protection, and flexible inter-module connections.

All plumbing calculations, design development, and drafting were completed by Delta-T Designs using building information modelling (BIM) to support coordination, consistency, and alignment with established northern best practices.

 

NuBrew Studio

Iqaluit, Nunavut – 2024

 

Delta-T Designs contributed to early mechanical design efforts for the NuBrew Studio, a 1,399 m² film production facility proposed for Iqaluit, NU. Working in support of Trapline Engineering, Delta-T Designs provided heating load calculations, ventilation analyses, and in-floor radiant heating design input as part of the project’s initial technical development.

The work addressed the unique demands of a large film studio in a sub-arctic climate, including the need for stable environmental conditions for production activities alongside the constraints imposed by extreme cold, limited infrastructure, and remote logistics. While the project did not advance to full mechanical system design and implementation, the early-stage analysis completed by Delta-T Designs helped establish a clear technical understanding of the facility’s performance requirements and constraints.

 

Mine Dry Tent Mechanical System Analysis

Goose Mine (Mine Dry Tent), Bathurst Inlet, Nunavut – 2024
 

Delta-T Designs supported Trapline Engineering as part of a joint technical review team for the Goose Mine Dry Tent mechanical system. The scope involved an independent assessment of the heating and ventilation systems proposed by others, with a focus on system adequacy, redundancy, and performance under extreme Arctic conditions.

Delta-T Designs performed independent heating load calculations using ASHRAE 169-2021 climate data, evaluated the capacity and limitations of the existing six-boiler used-oil heating plant, assessed terminal unit performance, and modelled ventilation heat losses across multiple exhaust scenarios. Additional analysis included HRV effectiveness, preheat coil requirements, and overall system resilience at peak design conditions.

The resulting report provided a defensible technical verification of the original design intent and included specific recommendations to improve heating capacity, redundancy, ventilation strategy, and energy performance for reliable operation in a high-risk Arctic mining environment.

 

Mechanical Design Standard

Qikiqtaaluk (QIC) High Arctic Housing, Nunavut – 2024
 

Delta-T Designs worked in collaboration with Trapline Engineering to develop the mechanical basis of design for the QIC High Arctic Housing program, producing a comprehensive design brief for modular residential buildings intended for deployment across Nunavut’s Qikiqtani Region.

The work integrated cold-climate best practices, Nunavut Good Building Practices, and applicable national codes to establish clear technical requirements for heating systems, fuel-oil storage, ventilation and heat recovery, domestic water systems, potable water storage, and sewage holding tanks. Design conditions were based on ASHRAE 169-2021 climate data and tailored to extreme Arctic temperatures and remote-community operational constraints.

The resulting document provided manufacturers and project stakeholders with a complete, high-level mechanical design framework, defining performance criteria, control strategies, and installation considerations necessary to support safe, durable, and maintainable housing in some of Canada’s most challenging environments.
