Lawrence, MA – Universal Window and Door has been selected to provide historic replica windows for Stone Mill, a 19th century mill being redeveloped into 86 apartments, for owner WinnDevelopment.
Universal will supply hundreds of windows from its new energy efficient 1060 Series for the transformation of the mill, the city of Lawrence’s oldest building. Developers of historic properties are often faced with the predicament of having to sacrifice energy efficiency in order to meet the stringent requirements of National Park Service or historic commissions preservation guidelines, and the new 1060 Series was designed to meet that market demand.
“Stone Mill will be among the first fossil-fuel free historic adaptive reuse projects ever done, utilizing high efficiency heat pump technology for heating, cooling, ventilation, and hot water,” said Christina McPike, WinnDevelopment’s director of energy and sustainability. “Given New England’s cold climates and high cost for electricity, it was critical to ensure that Stone Mill’s exterior thermal envelope was airtight and robust in order to maintain a low-energy, comfortable, and durable place to live. Universal’s thermally broken triple glazed windows met the challenge, satisfying historic preservation requirements to match the building’s original windows while meeting the project’s energy performance objectives.”
Constructed in 1845 as the Essex Company Machine Shop by the city’s namesake, Abbot Lawrence, the renovated building will use electricity instead of natural gas to produce heat and hot water. Designed by The Architectural Team (TAT), the building will use approximately 40% less energy and emit approximately 30% fewer greenhouse gases than a new construction, energy-code-compliant gas-heated building, according to WinnDevelopment.
The $38 million project is being funded in part by a nearly $2.9 million grant from the Merrimack Valley Renewal Fund’s Building Excellence Grant Program. When completed in early 2024, Stone Mill will provide a mix of one-, two- and three-bedroom units, with 69 units reserved for households earning under 60% of Area Median Income (AMI), as well as 17 market-rate apartments.
“With the increased focus on sustainability, our customers have been seeking a window solution that would deliver maximum energy efficiency while retaining our best-in-class historic replica window design,” said Jim Finn, president and CEO of Universal Window and Door. “And with the 1060 Series, we have answered the call.”
