Projected effects of climate change. "Seventy years from now, temperatures are likely to rise above 95°F approximately 20 to 40 days per year in the southeastern half of Virginia, compared with about 10 days per year today. Warmer temperatures will increase the use of air-conditioning, which will increase electricity consumption".
Lake Anna is one of the largest freshwater inland reservoirs in Virginia, covering an area of 13,000 acres (53 km 2 ), and located 72 miles (116 km) south of Washington, D.C., in Louisa and Spotsylvania counties (and partially in Orange County at the northern tip). The lake is easily accessible from Fredericksburg, Richmond, Charlottesville ...
Temperatures usually range from the 50s to the high 20s in December; while in January, it can range from the 40s, all the way down to the teens. Snowfall can be moderate, or considerably high during the winter. Almost every year, Virginia receives snow during December, and every year in January-February. In the summer, temperatures are hot and ...

A thermostatic mixing valve (TMV) is a valve that blends hot water with cold water to ensure constant, safe shower and bath outlet temperatures to prevent scalding . The storage of water at high temperature removes one possible breeding ground for Legionella; the use of a thermostat, rather than a static mixing valve, provides increased safety ...
Hot water reset, also called outdoor reset ( ODR ), is an energy-saving automatic control algorithm for heating boilers that are typically fired with fuel oil or natural gas. A hot water reset control loop measures the outside air temperature; this information is used to estimate demand or heating load as the outdoor temperature varies.
Heat of vaporization of water from melting to critical temperature. Water has a very high specific heat capacity of 4184 J/(kg·K) at 20 °C (4182 J/(kg·K) at 25 °C) —the second-highest among all the heteroatomic species (after ammonia), as well as a high heat of vaporization (40.65 kJ/mol or 2257 kJ/kg at the normal boiling point), both of ...
