Replacement Windows Case Studies: High-Performance Window Systems for Jefferson Green, a LEED for Homes Project in Richmond, VA

Wednesday, February 6th, 2019 by Britt Mangold


Jefferson Green is a progressive townhome community in Richmond’s Historic Union Hill neighborhood. Its three upscale townhomes are centrally located on Princess Anne Avenue across from Jefferson Park.  At first glance, the homes’ sweeping views of the city and sophisticated interior designs will command your attention. But there’s more to love than meets the eye.

Jefferson Green is the first multi-unit residential LEED for Homes project in the City of Richmond. For Developer Richard Cross of Hollyport  Ventures, achieving a high standard of energy-efficiency was a priority. The Jefferson Green townhomes were designed and built to be “Zero Energy Ready Homes.”

For a home to qualify as “Zero Energy Ready,” it must meet standards by the Department of Energy in seven key areas. The first of these, Optimized Thermal Protection, requires that the building envelope materials – including windows and doors -- meet or exceed next-generation building codes.


As a regional manufacturer of high-performance window systems, Custom Vinyl Products LLC (CVP) was especially qualified to supply the Jefferson Green project.  The DHA4 windows and PD21 sliding glass doors (except for the historic front) were custom-built by CVP. The DHA4 is a 1” triple-pane, low-e, argon filled double-hung window system. It carries a U-value of 0.20 and a Solar Heat Gain Coefficient (SHGC) of 0.18.*

Most window and door manufacturers are unable to achieve such high thermal standards and maintain the structural performance and value of a CVP window. Additionally, CVP windows are custom-built to specification and offer a profile that blends in with the neighboring historic buildings.

In 2018, Jefferson Green was one of four projects nationwide to be recognized with a Housing Innovation Award by the Department of Energy. It also received a Golden Hammer for Best New Construction award from Historic Richmond and Storefront for Community Design.

Custom Vinyl Products was honored to work with Hollyport Ventures and Health-E Community Enterprises on such an innovative and exciting project.

*The lower the U-factor, the more resistant the window is to heat flow. The lower the Solar Heat Gain Coefficient (SHGC), the less solar heat it transmits. For reference, average window U-Values range from 0.25 to 1.25; SHCG values generally range from 0.40 to 0.65. CVP windows surpass average values.
