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).

Angles solaires - Fondamentaux du positionnement solaire

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.

Comprendre le rayonnement solaire : la puissante source d'énergie de la Terre

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.
