我一直试图找到一些帮助我们家的住宅空中交换/通风系统一段时间，这可能是在GBA上的某个人可能能够在正确的方向上引导我，或者至少帮助我弄清楚一些人规格如果我最终必须自己作为房主，没有建筑或工程的任何背景。

洛杉矶县地图上，住宅约为2200平方英尺，气候3B。2016年新建，完成后购买。该计划是在进入之前尽可能地成为绿色的这个地方，但我不知道偏用会是多么糟糕。不幸的是，大多数房屋包括高VOC和甲醛材料，其中大部分地区都在尝试尽可能地拆除/更换或密封。取下了阁楼中的所有甲醛绝缘，并一直在运行商业大小的HEPA /木炭过滤的洗涤器。然而，甲醛水平下降了50％，因为这些努力和一般的改性，因为IAQ对IAQ对自己敏感的人来说，水平仍然太高。
Based on the TO-15 testing, I was able to identify that another major culprit for the poor IAQ is the existing interior paint and cabinetry. The solution I found online to deal with the cabinets is to seal them with the AFM safecoat polyureaseal BP, as I’m told that will greatly reduce the offgassing of formaldehyde and VOCs. And as for the interior paint on the walls (turned out to be a high VOC Glidden formula), I figured I could have all the existing paint sanded off, while everything that isn’t wall is covered with some poly and plan on keeping the HEPA/Charcoal scrubbers exhausting under negative containment simultaneously. Since the materials and paint all came back negative for lead and asbestos (I did these tests as a precaution, as a previous 2010 remodel of a newly tiled shower surprisingly came back afterwards as positive for lead at our last home), I am unaware of any harm in sanding down to the drywall or down to the orange peel or rough -whatever that textured layer is called between the paint and drywall itself. Maybe even wet-sand it off if VOC release during sanding is a major concern? Then, after the paint is sanded off, AFM new wallboard formula and primer/paint could replace it, as I’m told their Hard Seal is in there somewhere too and that these products are zero VOC. I figure this way I won’t be adding anything toxic, and that the hard seal in there will at least prevent offgassing of anything missed or left behind. I’ve only gotten as far as the idea, as I have yet to discuss this with anyone knowledgeable in VOC removal or VOC paint removal techniques. The abatement contractor I’d used before said he is willing to do the sanding and painting for me if I can tell him exactly what to do, since it really sounds the same to him as removing lead-containing paint, but I want to be sure I’m barking up the right tree with this approach first. The alternative was to seal the walls with just AFM safecoat hard seal( over the existing VOC paint) or just the transitional primer (that has the hard seal in it too) but I do not want to worry about VOCs on my walls ever again if avoidable.

And this all brings me to the ventilation system…the paint, the cabinets, and the insulation seem easy enough to remedy. The very stinkly laminate flooring I’ve yet to figure out, might remove and polish the concrete slab below if I have to. But the reality is that everything else in the house that cannot be removed practically or sealed will continue to offgas and leaving the windows open all the time is simply not practical either (nor will it be greatly effective, based on what I’ve been reading).
我在“如何完成所有”通风部分的GBA上阅读每篇文章，并在补充阅读读取的额外在线研究后，我感到非常自信，我需要一个带有ERV和专用管道的平衡系统。Possibly a dehumidifier if I find I need it, but that can be sorted out later as it need not be a part of the actual Ventilation system.. Now that I’ve tried running the existing exhaust fans in the house continuously, I realize there just isn’t much fresh air coming in and the continued off-gassing I cannot avoid remains a concern. I have consulted an OSHPD inspector, who agreed that the IAQ levels are not healthy for anyone, let alone someone with sensitivities, and have since been trying to find anyone with the expertise to help me figure out how to plan and put this together. Most HVAC companies have told me they aren’t experienced with these systems (even some that sell ERV/HRV units), and the few companies that were knowledgeable said they only take on higher-value projects like colleges, hospitals, etc. (not residential). And, again, my own abatement contractor offered to help if I couldn’t find anyone, but his own HVAC contractor said they have never done anything like this before and would need a third party engineer or someone with extensive experience to fill the knowledge gap if they were to try. The permit application requires an engineer anyway to sign off on the system prior to the permit being issued, and I haven’t managed to find anyone in Southern California willing or able to take this on that services the LA area in California. So, any suggestions on where I might need to look next? Or is this something my contractor and I could try to DIY without causing problems? My gut says the answer to the latter is a big ‘no’ but if I can’t find someone to help with this, I’ll have to figure something out. Cannot move in until I can breathe in there without becoming ill. Appreciate any advice and thank you for taking the time to read this.
