Hvac Load Calculations

The accurate calculation of heating and cooling loads is essential to provide a sound bridge between fundamental building design decisions and an operating building. If loads are substantially underestimated, occupants and users will likely be hot or cold. If loads are substantially overestimated, equipment will be oversize (usually wasting money, reducing efficiency, increasing energy consumption, and often imperiling comfort).

Solar Angles – Fundamentals of Solar Positioning

Two fundamental parameters determine how effectively your solar panels capture sunlight: orientation and tilt. These factors, when properly calculated, can significantly increase your system’s efficiency and return on investment.

Understanding Solar Radiation: Earth’s Powerful Energy Source

Solar energy is the result of electromagnetic radiation released from the sun by the thermonuclear reactions occurring inside its core. All of the energy resources on earth originate from the sun (directly or indirectly), except for nuclear, tidal, and geothermal energy.

Air Conditioning Condensate calculator

Air conditioning condensate is the water that is produced as a result of the cooling process in an air conditioning system. When the air conditioning system cools the air in a building, it removes moisture from the air, which condenses on the cool coils of the air conditioning system. This condensation is collected and drained away through a condensate drain pipe. The water that is collected in the condensate drain is typically referred to as air conditioning condensate.
