Supercharge Building Efficiency

Summary

This article provides a practical guide to Existing Building Commissioning (EBCx), a process designed to optimize building systems, enhance energy efficiency, and improve occupant comfort. It outlines the key phases of EBCx, from planning and assessment to implementation and handoff, offering actionable steps for building owners and managers. By following these best practices, building owners can significantly reduce energy consumption, lower operating costs, and create a more sustainable and comfortable environment.

** Main Story**

Okay, so you’re looking to cut energy costs and boost your building’s performance? Existing Building Commissioning (EBCx) might just be the answer. It’s a systematic way to make your existing building more energy-efficient, comfortable, and, let’s be honest, cheaper to run. Think of it as a tune-up for your entire building!

Here’s a step-by-step guide to get you started. It’s not rocket science, but it does require a thoughtful approach.

Phase 1: Planning – Setting the Stage for Success

First things first, you’ve got to plan. And I mean really plan.

• Define Your Goals: What do you want to achieve? A 15% reduction in energy consumption? Resolving those annoying temperature swings on the third floor? Be specific. Having clear objectives helps you measure success later.
• Assemble Your Dream Team: You’ll need a good Commissioning Provider (CxP). This person acts as your independent expert and they’ll be invaluable. A CxP who really knows their stuff is worth their weight in gold. They should have experience with buildings like yours, and understand your building’s systems inside and out. They can also help you navigate any potential roadblocks.
• Craft the CFR (Current Facility Requirements): Think of this as your building’s operational bible. It details how the building should be performing, the needs and performance expectations. This document guides the whole process. I once saw a project go sideways because the CFR wasn’t clear enough – a real headache!
• Create an EBCx Plan: The roadmap! This outlines the scope, budget, and timeline. Think about the order of the steps, and how long each will take.

Phase 2: Assessing the Current Situation

Time to get your hands dirty! This phase is all about understanding where you’re starting from.

• The Walk-Through: Grab a notepad and walk through the entire building, inside and out. Document everything you see: leaky faucets, flickering lights, strange noises coming from the HVAC system. Take pictures, too!
• Dig Into the Documents: Comb through those system specs, control system diagrams, and especially past energy bills. You can often spot patterns or anomalies that point to inefficiencies.
• Talk to People: Interview the facilities staff and building occupants. They’re the ones who experience the building every day. What are their concerns? Where are the problem areas? Their insights are gold. Don’t skip talking to the staff, honestly.

Phase 3: Investigation – Unearthing Opportunities

Now, it’s time to turn detective. You’ll be digging deeper to uncover those hidden opportunities for energy savings.

• Testing and Analysis: Run detailed tests on your building systems – HVAC, lighting, controls. Check equipment calibration, analyze energy data, and review your building automation system (BAS).
• Prioritize ECMs and FIMs: Based on your findings, create a prioritized list of Energy Conservation Measures (ECMs) and Facility Improvement Measures (FIMs). These are the specific actions you’ll take to improve efficiency. The measures with the biggest impacts are the ones you want to do first.
• Consider Everything: ECMs and FIMs could be anything from simple system adjustments to big equipment upgrades.

Phase 4: Putting Your Plan into Action!

Okay, time to roll up your sleeves and get to work. This is where you implement those ECMs and FIMs you identified.

• Careful Implementation: Carefully monitor the implementation process to make sure things go smoothly.
• Verification is Key: Once the changes are complete, verify their effectiveness! Performance testing and measurement are critical here. Track energy consumption, monitor system performance, and gather feedback from those building occupants again.
• Document Everything!: Keep meticulous records of all changes and updates. This ensures the building keeps operating at it’s peak performance for years to come.

Phase 5: Handoff and Looking Forward

Long-Term success is the name of the game. The handoff phase is all about setting your team up for the future.

• Training is Essential: Train your operations and maintenance staff on all the implemented changes and how to maintain optimal system performance. They’re the ones who’ll be living with these changes day in and day out!
• Ongoing Commissioning (OCx): Develop an OCx plan to continuously monitor and optimize building performance over time. Think of this as a health check-up for your building. OCx includes regular energy use monitoring, benchmarking against industry standards, and refining your CFR to reflect evolving needs, and you won’t regret the time spent on it.
• It’s an Investment: This final step ensures your initial investment in EBCx keeps paying off with continued energy savings and cost reductions.

So, what do you think? Are you ready to take the plunge? EBCx isn’t a quick fix, it’s a commitment to continuous improvement and one that I think you’ll find worthwhile. Ultimately, by embracing this process, you can unlock your building’s full potential for energy savings and sustainability, it’s a win-win scenario!
