Press Release:


The HERS Index is a comprehensive measurement of a home’s energy efficiency and there are a lot of important reasons why homeowners or potential buyers should have a home energy rating performed on a property.  Outside of the mortgage loan, heating, cooling and water heating constitute the largest cost of owning and maintaining a home.  Now they have an opportunity to get up to speed on these opportunities with PACE (Property Assessed Clean Energy).  If you are about to purchase, the HERS Index Score will tell you how well the home performs energy-wise.  Buyers receive a report will outline the energy features of the home and the expected cost of utility bills.  It’s also invaluable to  in helping to  determine how efficiently an existing home is operating and where modifications can be maaed for greater energy savings When selling home, a low HERS Index Score can command a higher resale price.



Christopher Hull, principal of CAH Architecture and Design, LLC, a high-end residential, multifamily,and commercial architecture firm will discuss HERS standards, as well as  several of his other energy efficient projects thisThursday night on “Greenwich Matters” with Mark Betz, founder and CEO of the Norwalk firm, Green View Building Products,along with Green View’s Sales Director Rob Kennedy, and Sam Romeo, chairman of the Greenwich Housing Authority. 



Hull’s interest in sustainability began with his avid love of the outdoors and has translated into a career-long campaign to incorporate energy efficiency, preservation, and environmental concern into CAH's projects. He is committed to lifelong learning and has professional experience in passive solar, LEED certified buildings, geothermal, and high energy-efficiency buildings.  He will talk about his ongoing Montauk Modern project, which will require either solar or geothermal power sources to meet the exacting requirements necessary to obtain a HERS rating. Additionally, it will have to adhere to strict energy conservation standards. He will also detail the energy efficiency challenges of his Crooked Highway project involving a 7000 sq ft home that consists of 67% glazed area on the first and second floors. They key has been to incorporate high-performance glazing, continuous rigid insulation, and well-sealed basement spaces.



The program is the latest in a bi-weekly series of proven strategies and in-depth examinations of the benefits of building with an eye on its long-term effects on the environment.  “HERS is a recognized energy efficiency standard that provides metrics that can make a real difference for homeowners.”said Betz. “We’re excited to help our audience understand the benefits.”
