I’ve noticed the same thing—energy upgrades get all the attention at first, but water-saving features are catching up, especially with droughts becoming more common. Sometimes I’ll suggest starting with a quick water audit before picking fixtures, just to see where the biggest wins are. Has anyone tried integrating greywater systems? Curious if they’re worth the hassle in a typical reno.

Tried it once on a mid-size project, and honestly, I’m still not convinced. The upfront cost and the extra plumbing complexity made it a tough sell, especially since local regs kept changing. Plus, maintenance is a headache if the owners aren’t really on top of it. Maybe it makes sense in new builds or bigger multifamily setups, but for a standard reno? I’d want to see some hard numbers before recommending it again. Anyone actually seen a payback that justifies the hassle?
Title: Choosing Between Energy Efficiency Or Water Savings For Green Building Points?
I’ve run into the same greywater debate on a few projects, and it always seems to come down to whether water savings or energy efficiency gives more bang for the buck—especially when you’re chasing green building points. From what I’ve seen, energy upgrades (like better insulation or high-efficiency HVAC) tend to have clearer payback periods and are easier to quantify, at least in my area. Water systems like greywater feel like a bigger leap, both in terms of cost and complexity, unless you’re in a place with high water costs or severe restrictions.
Has anyone looked at how different rating systems (LEED, Green Star, etc.) actually weight water vs. energy? I've noticed LEED seems to give more points for energy, but maybe that’s shifted recently? Curious if anyone’s done the math comparing a modest greywater setup versus, say, upgrading windows or adding solar panels. Which one actually gets you closer to certification—or makes more sense for owners in the long run?
I did have one client who was fixated on water savings because they had a massive garden and some local rebates, but honestly, after factoring in the maintenance (filters clogging, occasional odors…), they started wondering if just collecting rainwater would’ve been simpler. Made me wonder if these systems are really designed with typical homeowners in mind or if they’re just better suited for larger-scale or institutional projects where there’s staff to keep everything running.
Is it just me, or do most people end up prioritizing energy upgrades over water systems unless there’s a really compelling reason not to? I’d be interested to hear if anyone’s seen a project where water savings actually tipped the scales—either for points or real-world savings.
You’re not off base at all—energy upgrades really do tend to be the low-hanging fruit, especially with LEED’s current weighting. Here’s what I’ve noticed:
- LEED v4 still leans heavier on energy (up to 33 points for Optimize Energy Performance vs. 11 for Water Efficiency).
- Payback on insulation or HVAC is usually more predictable, like you said.
- Greywater/rainwater systems are great in drought-prone regions or where water rates are sky-high, but yeah, maintenance can be a dealbreaker for most homeowners.
Honestly, unless water is a huge pain point locally or there are killer rebates, most folks stick with energy first. Your take on rainwater being simpler for gardens is spot on—less hassle, fewer moving parts. Still, it’s cool to see people pushing the envelope with water systems, even if it’s not always the “easier” path.
Honestly, I get why most people chase the energy points first—it’s just easier to model, and the ROI is clearer. But I’ve seen projects where water ended up being the real pain point, especially in places with tiered water pricing or strict usage caps. Sometimes, a well-designed greywater system pays for itself faster than you’d expect... but only if you’ve got someone willing to keep it running smoothly. Energy is the “safe bet,” but I wish LEED would give water a bit more love, considering where things are headed climate-wise.
