   这取决于您的加热和冷却系统。
   如果您没有机械冷却和使用Hydonic Radiant Heat，HRV产品的销售代表可以帮助您尺寸和设计其分布。如果您可以通过您的房子运行管道，安装可能是Dyi Plus和电工。

   If you are tying into a force air system than it gets more complicated. I've seen HRVs added onto force air systems that I'm not convinced the installer really new how it would actually function. Again, I think its worth calling an HRV manufacturers representative. For new construction at least they are typically sufficient for the design of the system without employing an mechanical engineer.

   机械工程师。然而，没有多少MES在住宅HVAC设计中有经验或工作，因此确保他们这样做。
   You may want to contact Justin Wilson @http://www.buildwithbps.com。他可能能够在丹佛给你一些名字。

   您可能希望联系Paul Kriescher，这是一个工作的能源顾问Lightly Treading Energy & Design。保罗应该能够推荐住宅通风承包商。

   Other good sources of information are Dennis at About Saving Heat and Robby at Energy Logic.
   Please explain your system a little more, and we may have more suggestions.
   Is the home built yet?, if so, what year?
   它目前有什么样的HVAC系统？
   What size is the home?
   Have you had a blower door test?
   Colorado的Xcel Energy目前提供补贴的家庭能源审计。这些通常是通过轻微的踩踏并且仅需120美元来完成。没有Xcel的补贴，这些通常运行600美元到1000美元。它们包括鼓风机门测试和红外摄影。

   Thanks Guy's for all the good advice. I started with Energy Logic several years ago when they were still doing resendential for retail clients-now then only work with developers. Presently using GB3 who are good but ventillation systems are outside their range of expertise. Bringing in my own HVAC Guy next week for a consult but feel someone with an enginerring degreee in this is preferable. Home is 11 years old, semi custom Bill Wah'l ranch (3800') which is now super tight at .22 NAC.Furnace system is still old but usable with CleanEffects, seperate DeHumidifier and Humidifier. One extra duct from outside with aflapper valve controlled by HVAC. Home pretty comfortable except in 2 rooms. GB3 Energy (auditor was trained by Energy Logic) feels Whisper Green ventillation fan will help in one room but need to increase overall overall ventillation without incurring a huge energy cost. This is long range plans and may not be implemented until a few years from now.

   Arvin,

   Whisper Green fans are a good choice for rooms that need it, and they keep it simple. Here's a video on how they are controlled, either by motion sensor, or manual switch:http://www.iaqsource.com/article.php/understanding-panasonic-whispergreen-fan-controls/?id=152

   但他们没有提供“平衡”通风。最经济的均衡解决方案是松下的威士忌惮地点ERV：http://www2.panasonic.com/webapp/wcs/stores/servlet/ModelDetail?storeId=11201&catalogId=13051&itemId=175432&catGroupId=119516&surfModel=FV-04VE1&displayTab=O

   他们将重新夺回出口空气中的66％的热量，甚至应该为房子提供足够的全空气。

   The degreed mechanical HVAC engineer will probably stick closely to the ASHRAE recommendations:http://epb.lbl.gov/publications/lbnl-54331.pdf

   他们告诉你提供多少空气，但不是如何测量空气质量，以最大限度地减少粉丝运行时。

   CO2测量通常建议控制通风空气，但我没有看到实用的住宅控制。

   A furnace-mounted HRV's installed cost will be hundreds if not thousands more than the WhisperComfort, and you are forced to ventilate the whole house, which might not be necessary.

   现有炉子上的外部空气管道是一种差的方法，主要是因为如果没有呼气，那么你没有得到任何通风。（除非您安装一些复杂，不寻常的控件）

   Arvin,
   有关住宅通风的更多信息，请参阅Designing a Good Ventilation System。

   By the way, if your home has 0.22 natural air changes per hour (NAC), you are mistaken to think that it is "supertight." That value is roughly equivalent to 4.4 ach50 -- not particularly tight.
