Heat Loss Calcs

Heat loss calcs are used to work out the quantity of energy required to heat a building and the amount to invest in efficient heating technology (when the external conditions are colder).  The size of the heating installation depends largely on the performance of the building fabric. To calculate the size of the heater(s) required […]

Pros and cons of natural ventilation energy efficiency

Energy efficiency is the keystone of the revolution in new buildings; one concept that has been suggested is natural ventilation in order to reduce the energy consumption (as opposed to mechanical ventilation). The main idea is to use the difference of temperature in the building to generate the air flow (without any fan). Thereby, natural ventilation […]
