Despite significant advances in water heating technology, open-combustion (atmospherically vented) gas water heaters remain surprisingly common in residential construction. These units draw combustion air from the surrounding room and rely on the natural buoyancy of hot exhaust gases to vent through a metal flue. Building science expert John Straube has fittingly described this arrangement as […]
Noise pollution is one of the most common complaints homeowners raise about their living spaces, yet acoustic performance rarely gets the attention it deserves during the design and construction phases. While most builders focus on thermal comfort, air sealing, and structural integrity, the science of creating a truly quiet home involves a distinct set of
When builders and homeowners discuss insulation, the conversation almost always turns to R-value. Building energy codes specify minimum R-values for walls, roofs, and floors, and most people understand that higher numbers mean better insulation. But what exactly does R-value measure, and how should it be applied in real-world construction? This article takes an educational look
Air source heat pumps have become a leading choice for home heating and cooling, offering excellent efficiency in both seasons. In heating mode, however, they face a limitation that gas furnaces do not: heating capacity drops as outdoor temperatures fall. When a heat pump cannot deliver enough warmth alone, the system activates electric resistance strip
When homeowners and builders discuss energy efficiency, attention often falls on insulation, windows, and air sealing. Yet one of the most overlooked opportunities for energy savings lies within the mechanical room. Heating and cooling typically account for the largest share of a home’s energy use, and oversized equipment wastes energy while degrading comfort. The key
The vision of high-performance housing – homes that are energy-efficient, healthy, comfortable, and durable – has long been pursued by builders and designers. Yet a persistent challenge remains: delivering these benefits at a price ordinary buyers can afford. As highlighted in a Green Building Advisor feature on affordable high-performance housing, a developer in northern Kentucky
Linseed oil paint is one of the oldest painting mediums still in use, and for good reason. This centuries-old, plant-based coating offers exceptional durability, vapor permeability, and a beautiful finish that modern petrochemical paints struggle to match. Whether you are restoring a historic property or simply want a nontoxic alternative for your next project, understanding
The dream of owning a high-performance home often collides with the reality of rising construction costs. In many housing markets, the gap between what builders can deliver and what average families can afford continues to widen. Yet a growing body of evidence suggests that affordable high-performance homes are not only possible but practical when builders
The world is getting hotter, and the demand for cooling is rising faster than ever. Last year was the hottest on record, with average global temperatures reaching 14.98 degrees Celsius, surpassing the previous high set in 2016. As heat waves become more frequent and intense, the need for efficient air conditioning grows urgent. Yet conventional
If you live in a two-story home, a Cape Cod, or a Colonial, you have likely experienced a hot second floor during summer. The upper level can run 5 to 10 degrees Fahrenheit warmer than the floor below, making bedrooms uncomfortable and living spaces nearly unusable. This temperature difference is especially common in regions like
