Our Story
Built in the Interior of BC. Trusted Across Western Canada.
Inland Technical Services was founded in Kamloops in 1986 by Henry and Vickie Pejril. What began as a testing and balancing firm serving the Thompson Okanagan has grown into an independent building systems verification practice with offices in Kamloops and Kelowna.
Our services now include testing and balancing, building commissioning, integrated systems testing, O&M documentation, recommissioning, monitoring-based commissioning, and ongoing commissioning support.
Healthcare has been a major part of ITSL’s work for decades. Our team has supported hospital projects, long-term care facilities, clinical buildings, medical office buildings, and phased renovations in active healthcare environments. That experience has shaped how we approach coordination, documentation, field testing, owner communication, and closeout.
Since taking ownership in 2020, Luke Buis has continued ITSL’s focus on independent, field-based verification while expanding the firm’s commissioning, healthcare, recommissioning, energy optimization, and CAN/ULC S1001 Integrated Systems Testing services.
ITSL does not design or install the systems we verify. Our role is to measure performance, test operation, and document findings. From there, we identify issues and support resolution for owners, consultants, contractors, and facility teams.
Our technical strength comes from the field. Many of ITSL’s commissioning providers have testing and balancing experience, giving our team a practical understanding of airflow, hydronic flow, pressure relationships, controls operation, system readiness, and the roadblocks that affect commissioning and closeout.
Luke Buis is Past President of the BCxA Western Canada Chapter and remains active on the chapter board. He also serves on the SICA Board of Directors and has contributed to CSA Group technical subcommittee work related to CSA Z5000 and CSA Z5001. ITSL’s team includes LEED AP BD+C, AScT, P.Eng., ACP, commissioning, TAB, controls, electrical, mechanical, O&M documentation, and building operations experience.
ITSL is also a BC Hydro Continuous Optimization Program approved service provider and a ULC-certified provider for CAN/ULC S1001 Integrated Systems Testing.

Vision Statement
To be a trusted leader in building systems commissioning and TAB by raising expectations, improving real world outcomes, and setting a higher standard for quality and accountability in our industry.
Mission Statement
To deliver technically rigorous commissioning and building performance services — testing and balancing, CAN/ULC S1001, and more — through hands-on field involvement, objective expertise, and a commitment to getting systems working as intended before and after turnover.
Our Culture
Our Values
Teamwork
Building systems are delivered by project teams, not individuals. We work with owners, consultants, contractors, and operators to support practical issue resolution and successful project outcomes.
Excellence
We hold our work to a high technical standard. Our process is based on field verification, measured results, calibrated instruments, clear procedures, and a strong understanding of building systems.
Communication
Good commissioning and TAB work depends on clear communication. We document findings in a way that is factual, practical, and useful to the people responsible for making decisions and correcting issues.
Continuous Learning
Buildings, codes, standards, controls, and equipment continue to change. We invest in learning so our team can keep improving and bring current technical knowledge to each project.
Factual Reporting
Our reporting is based on what we observe, measure, and verify in the field. We focus on clear facts, traceable results, and objective documentation rather than assumptions.
Continuous Improvement
We look for ways to improve our process, our documentation, and the outcomes we help deliver. This applies to our own work and to the building systems we review, test, and verify.
Our Standards
Code of Ethics
Inland Technical Services performs its work in accordance with applicable industry standards such as NEBB, AABC, and the BCxA.
- We serve our clients with integrity, competence, and objectivity. Our role is to provide clear, factual, and independent information based on field verification, measured results, and professional judgment.
- We advise client and project personnel of problems encountered during the work and provide practical recommendations to support resolution.
- We assign personnel to projects who are qualified by knowledge, experience, training, and character.
How We Work
What Drives Every Engagement
Independence
We provide objective verification on behalf of the owner. ITSL does not design or install the systems being tested, allowing our team to focus on actual system performance, clear documentation, and practical project outcomes.
Technical Excellence
We test thoroughly, document clearly, and track deficiencies through to resolution. Our process is built to support consultant review, owner acceptance, AHJ review, and long term facility reference.
TAB Cross Training
Our commissioning and IST teams are supported by decades of TAB experience. This gives our providers a stronger understanding of airflow, hydronic flow, pressure relationships, smoke control, pressurization, and the real field conditions that affect integrated system performance.
Field Presence
With offices in Kamloops and Kelowna, ITSL stays close to the work throughout construction. Our team is available for planning, coordination, field testing, deficiency follow up, and final verification across BC and beyond.
