Heat Loss: The Latest Architecture and News

Heat waves are becoming more and more frequent worldwide, prompting architects to reconsider how building envelopes are conceived and designed. The focus is no longer solely on limiting heat loss during the colder months, but also on controlling how much heat enters buildings during periods of intense solar radiation. By understanding solar shading as a design decision rather than a decorative or interior-conditioning element, it becomes part of passive energy-efficiency strategies that can contribute to thermal and visual comfort while reducing cooling demand.

Throughout history, doors—and later automatic doors—have served a far greater purpose than merely marking an entrance or exit. They define thresholds, guide the flow of movement, and subtly shape the way people interact within a space. We can trace their evolution back to the 1st century, when Heron of Alexandria devised a steam-powered door—an early example of technology merging with architecture. Since then, contactless automatic door systems have incorporated technological advancements that enhance operation and redefine their role within buildings. Today, they are integrated across a range of building types and scales, acting as transitional elements that enhance comfort, energy efficiency, and the overall quality of indoor spaces.

A Trombe wall is a passive solar building feature that enhances thermal efficiency. Positioned on the sun-facing side of a structure, it consists of a wall made from materials like brick, stone, or concrete, and a glass panel or polycarbonate sheet placed a few centimeters in front of it. Solar radiation penetrates the glass during daylight hours and heats the masonry wall. This wall then slowly releases the stored heat into the building during the cooler nighttime hours, maintaining a more consistent indoor temperature without the need for active heating systems.

Some of the most picturesque projects are those built in the mountains; the rustic cabin wrapped with a floor-to-ceiling glass panel that overlooks the snow-covered trees. Visually, the architecture exudes an enchanting feeling, but is it truly a habitable space? When houses are built on an elevation of 3,000 meters, installing a fire element alone is not efficient or sustainable. Spaces on such altitudes or particular geographic locations require to be treated thoroughly, beginning with the architecture itself. Whether it's through hydronic in-floor heating systems or wall-mounted chimneys, this interior focus explores how even the most extreme winter conditions did not get in the way of ensuring optimum thermal comfort.

How much of our utility bills are devoted to heating and cooling? What is the R Value of fiberglass? In fact, what is an R Value?

Senator Windows answers these questions with a new infographic driven at “reducing heat loss in your home.” Aimed at both designers and home users, the infographic features a blend of statistics, diagrams, and definitions outlining how heat loss occurs, and how to mitigate against it.

We have republished the infographic below, offering a useful introduction to an almost universal issue in both the design and occupation of buildings.
