Hello, All -
What is the lowest HERS Index that you know of for a real (not planned) multifamily residence? What type of home is it (duplex, townhouse, garden, low-rise), where is it located, and what are the significant features that contributed to its high-performance (envelope design, fenestraiton, construction materials, passive/active features, appliances, lighting, control strategies, etc.?) Roughly what square footage and exposures also?
I'm looking for indices that are taken PRIOR to the benefits of wind or solar energy (PV or thermal), but INCLUDING Geothermal HVAC if necessary. Thank you for your insights!
