>The Lodenareal, a new neighborhood of apartment blocks in Innsbruck, is featured in an article lauding their low-energy, high-quality Passivhäuser, or “passive houses”; the premise behind these buildings is that they are so well insulated that the heat generated from lights and electrical appliances is enough to warm the rooms, and at the same time having enough fresh air coming in to avoid unwanted moisture. This way, you keep cool in the summer and warm in the winter, and your heating bill is basically zero.
An acquaintance of mine lives in one of the apartments, and she loves it. I hope more of these get built.
