Our Degree Day Calculator is the easiest and most reliable way to calculate Heating and Cooling Degree Days. No more copy/pasting Excel data, no complicated formulas - just a single click for your specific location. Being used by architects, energy, real estate and factory managers around the world, it's safe to say that it is indeed one of the best tools available.

These days, we provide thermal comfort in winter by heating the entire air volume in a room or building, an approach that consumes a lot of fossil fuels. In this series of articles, LOW←TECH MAGAZINE focuses on our forebear’s concept of heating, which was more localized. They used radiant heat sources that warmed only certain parts of a room, creating micro-climates of comfort, and they used personal heating sources that warmed specific body parts. It would make a lot of sense to restore this old way of warming, especially since newer technology has made it much more practical, safe, and efficient. By placing heating technology in a historical context, LOW←TECH MAGAZINE challenges the high-tech approach to sustainability and highlights the possibilities of alternative solutions.

Inventor, engineer and MacArthur Genius Grant-winner Dr. Saul Griffith thought he was an eco-prude, until he audited his total power consumption and learned he burns three times as much energy as the average European, and eight times as much as the average Carribeaner. Watch as he unveils Wattzon.com, a free online tool anyone can use to gain a deep understanding of their total energy footprint - and how to reduce their role in climate change.

Otherlab is a research and development firm focusing on renewable and clean energy, robotics, automation, digital fabrication, adaptive textiles, advanced manufacturing, and computational design tools. Similar to an accelerator/incubator, but with internally developed ideas, we nurture projects through the initial R&D phase, to forming entities within Otherlab, and eventually fundraising and spinning out into independently operating companies. In the past 5 years, Otherlab has collaborated with Stanford, MIT, Berkeley, Harvard, NASA, Autodesk, GE, Ford, Google, Motorola, IDEO, and a host of...

What would we do without energy? The short answer is, “Nothing, absolutely nothing.” And sadly, most people know next to nothing about energy and its fundamental role in society and life itself.
