+===== Meaning 1 =====
-For cold-climate performance, details like equipment selection, airflow design and thermostat setup matter just as much as the unit itself. When homeowners search [[https://lawrencewilbert.com/read-blog/40260_heat-pump-installation-near-me-what-denver-homeowners-should-know.html|heat pump installation near me]], it helps to start with a home evaluation that considers comfort preferences.(Image: [[https://i.ytimg.com/vi/3-PXklXACss/maxresdefault.jpg|https://i.ytimg.com/vi/3-PXklXACss/maxresdefault.jpg]]) A proper load calculation can prevent issues like short cycling or uneven temperatures. Installation planning may also include duct adjustments or mini split installation for homes with [[https://www.wikipedia.org/wiki/tricky%20layouts|tricky layouts]].(Image: [[https://insulationprosco.com/wp-content/uploads/2024/08/StockCake-Suburban-rooftop-view_1724417067.jpg|https://insulationprosco.com/wp-content/uploads/2024/08/StockCake-Suburban-rooftop-view_1724417067.jpg]]) In addition to installation, routine maintenance supports performance through Denver’s changing seasons. UniColorado Heating & Cooling focuses on practical planning and clear explanations so homeowners understand options, timelines and what to expect from a heat pump system.(Image: [[https://homeinsulationbusinessroundup.weebly.com/uploads/1/4/9/1/149181504/which-way-to-face-insulation_orig.jpg|https://homeinsulationbusinessroundup.weebly.com/uploads/1/4/9/1/149181504/which-way-to-face-insulation_orig.jpg]]) Some households may explore whole-home electrification Denver options, including electrical services and complementary upgrades. By combining the right equipment with good airflow and maintenance planning, Denver homeowners can improve comfort while supporting energy-saving HVAC upgrades over time.
+==== Alternative Terms ====
+/*i.e. alternative names meaning the same thing*/
+==== Definition ====
+A **natural class** is a class which was not artificially created as part of the solution but derived from the problem domain of the software.
+==== Description ====
+Someone with no technical knowledge but knowledge about the application domain can come up with natural classes as they are just concepts and abstractions derived from the problem domain. Software typically also requires some [[artificial class|artificial classes]] for its solution but the [[principles:Model Principle]] tells to avoid them in favor of natural classes if there is no greater benefit from introducing an artificial class. According to [[principles:Model Principle|MP]] and [[principles:Tell don't Ask/Information Expert|TdA/IE]] functionality is mapped to natural classes and artificial ones are only created for special purposes. Often [[patterns]] make creating artificial classes necessary, although this is not always the case.
+Note that natural classes and [[domain class|domain classes]] are related but not the same notions. Each domain class is a natural class but not the other way around. A domain class is a class which is part of a [[patterns:domain model]] (typically stored in a database, etc.) whereas a natural class is just one which is not artificially created. Even classes like ''DatabaseConnection'' or ''HttpRequest'' are natural classes, because they represent a natural concept which exists independent of the software. Classes like ''BeanFactory'' or ''InvocationHandler'' on the other hand are not meaningful outside the context of the software, of the solution. So these are artificial classes.
+==== Examples ====
+  * Classes like ''Book'', ''User'', ''Contract'', ''Order'', ''OrderItem'', etc. are natural classes and also domain classes.
+  * Classes like ''Button'', ''TextField'', ''DatabaseConnection'', ''HttpRequest'', ''Time'', ''Integer'', ''Velocity'', ''Voltage'', etc. are also natural classes but typically not domain classes.
+  * Classes like ''ActionListener'', ''ConnectionAdapter'', ''BeanFactory'', ''InvocationHandler'', etc. are //not// natural but artificial classes.
