The following links provide more detailed information on building envelope components and the minimum thermal requirements of envelopes for different climates as defined by ASHRAE. These complexities must be considered by a designer who intends to deliver comfort and energy efficiency. The flow of heat through a building envelope varies both by season (heat always flows from hot to cold and generally flows from a building in winter and to a building in summer) and by the path of the heat (through the materials of a buildingвЂ™s skin, or by outdoor air entering).

When external conditions are very close to the desired internal ones, the envelope often begins as an open structural frame, with pieces of the building skin selectively added to modify only a few outdoor forces. Kite Breeze is offered in White Glaze, Terracotta, and Dune. Architects can rotate the blocks any which way and even layer them to create unique patterns. This may also be true where there are unwanted external influences such as noise or visual clutter. Glen-GeryвЂ™s contemporary take on the patterned masonry breeze-blocks that were popular in the 1960s, Kite Breeze features a 3ВЅ'-thick x 113/8'-square frame with a setback triangular aperture. In harsh climates, the designer frequently conceives the building envelope as a closed shell and proceeds to selectively punch holes in it to make limited and special contact with the outdoors. The range of choices in envelope design can be illustrated by two opposite design concepts: the open frame and the closed shell.

The choice of envelope is governed by the climate, culture, and available materials. The envelope may be composed of membranes, sheets, blocks and preassembled components.

Extra insulation retains heat in winter, but operable windows passively cool it in summer.ДЇrom an energy flow perspective, the envelope is a composition of layers with varying thermal and permeability properties.

It also uses a light roof and darker walls to repel summer sun but absorb winter sun. The Secret of Next-Gen Drywall Firestopping Solutions. Flexibility is the key to designing for these climates.В The Aldo Leopold Center in Wisconsin, the first building to be LEED certified as carbon-neutral,В uses deep overhangs to allow low winter sun in through the windows to heat up a high-mass concrete slab inside, while blocking high summer sun.

Many вЂњtemperateвЂќ inland climates actually have two extremes-cold in winter, hot and humid in summer. The Windows and Envelope Materials Group conducts research, development and demonstration projects to reduce the energy-related impacts of building. The Aldo Leopold Center in Baraboo, Wisconsin.
