The structures that we live in are complex assemblies of materials, combined and attached to each other with an even more complex assortment of fasteners. They get little respect from us, however, when they don't perform the way we expect. For a home to be comfortable, it needs to meet certain criteria. Smart Solar Box Although there are building and energy codes that dictate how a building should be constructed, the final judgment will come from the homeowner. If a home passes the preliminary and final inspections by code officials, how can it fail to be comfortable for the homeowner? Just like a recipe for a delicate pastry, ingredients must be combined in the correct proportion at the proper time. Strict attention must be paid to every detail for the outcome to be favorable. Once the pastry comes out of the oven, it is too late to add a forgotten ingredient and there is little chance that the consumer will overlook the omission. When a detail is overlooked on home construction, it will most surely surface later on as a comfort problem. The "comfort problem" may be the homeowners discomfort when the utility bill arrives, or it may be temperature variation between different levels or rooms. It may also be a humidity problem that is hard to pinpoint but somehow makes the temperature feel different than what is shown on the thermostat.
