Understanding the Water Use Baseline for Older Buildings

Understanding Water Use Baselines for Older Buildings: A LEED O+M Perspective

If you’ve ever wandered through a building constructed before 1950, you might’ve noticed a few quirky details — perhaps vintage plumbing fixtures or unique architectural styles. While historic charm is appealing, there’s often a hidden issue lurking beneath that façade: water wasted due to inefficient systems. That’s where understanding the water use baseline for such buildings becomes crucial, particularly in the context of LEED AP with Operations and Maintenance (O+M).

What’s the Baseline for Indoor Water Use Reduction?

For buildings with a certificate of occupancy dated 1950 or earlier, the existing water use baseline is set at 150%. Now, you might wonder, “Why 150%?” It stems from an acknowledgment of the water inefficiencies typical of older structures. In many cases, these buildings lack the modern water-saving fixtures and systems that have become standards in new constructions. It’s almost as if these architectural gems were built in a different era, where conservation wasn’t, well, top of mind.

Why Does This Baseline Matter?

Understanding this baseline isn’t just academic; it’s a game-changer for building owners and managers aiming to boost their sustainability profile. The 150% baseline provides a realistic metric for establishing how much water use reduction is achievable. Think of it as your starting point on a fitness journey. If you start with a clear understanding of your current capabilities, it’s much easier to set targeted, attainable goals.

You see, this baseline helps in two significant ways:

1. Strategic Planning: By knowing that older buildings typically use more water, owners can more effectively strategize their upgrades and renovations. This provides a clear path for determining the types of water-efficient fixtures — like low-flow faucets and dual-flush toilets — that could contribute to reducing their overall water consumption.

2. Tracking Progress: The 150% baseline also serves as a benchmark against which water-saving measures can be measured. It’s like setting a scoreboard; you can visualize improvements over time. This tracking is essential for sustainability reporting and can even enhance a building’s credibility in the competitive market of green certifications.

What Can Be Done to Reduce Water Use?

Given that the baseline is acknowledged, the next steps revolve around making impactful changes. Owners of older buildings can pursue several strategies to meet and even exceed reduction targets. Here are a few ideas that could leave a lasting impact:

• Upgrade Plumbing Fixtures: Installing modern fixtures like water-efficient toilets and faucets can dramatically decrease water usage. Many of these fixtures come with a myriad of styles, so you won't have to sacrifice aesthetics for functionality.

• Irrigation Optimization: If the building has landscaping, consider using smart irrigation systems. These technologies can adjust watering schedules based on weather conditions, keeping your plants lush without flooding your garden beds.

• Cooling Systems: If the building includes cooling systems, ensure they’re regularly maintained and optimized. Older systems might need adjustments to prevent wasting water during operation.

• Educate Occupants: Last but not least, engaging with occupants about water-saving practices can lead to behavioral changes that contribute significantly toward conservation efforts. Sometimes, it just takes a friendly reminder to be more mindful about water use.

The Bottom Line

Water conservation in older buildings isn’t just good practice; it’s critical to achieving broader sustainability goals. By understanding the established baseline of 150%, facility managers and owners can plan strategically, set achievable targets, and ultimately foster a culture of sustainability within their buildings.

Indeed, embracing water use reduction measures not only contributes to ecological preservation, but it can also increase a building’s market appeal — who wouldn’t want a place that’s hard on the environment and easy on the wallet?

So next time you stroll through an older neighborhood, take a moment to appreciate the history of those buildings but also reflect on the potential they hold for making significant strides in sustainability. The journey toward greener operations is not just about what we can do today but how we can transform the legacies of the past into something much more eco-friendly for the future. After all, every drop counts!

By promoting intelligent strategies for water use reduction, older buildings can truly shine — both as majestic structures and as sustainable spaces for years to come.
