Grams per Brake Horsepower Hour (g/bhp-hr) is a measure of the amount of fuel consumed by an engine to produce a unit of power. It is a standard measure of the efficiency of an engine and is widely used in the automotive and aviation industries. The lower the g/bhp-hr value, the more efficient the engine is in terms of fuel consumption. This metric is important for both environmental and economic reasons, as it allows manufacturers to design engines that are more fuel-efficient and emit fewer pollutants. The g/bhp-hr value is calculated by measuring the amount of fuel consumed by the engine and dividing it by the amount of power produced in brake horsepower (BHP) over a specified period of time, usually an hour. This measure is used to evaluate the performance of different types of engines, such as gasoline, diesel, and natural gas engines. It is also used to compare the efficiency of different models of engines within the same type. The g/bhp-hr value is an important consideration for regulatory agencies, as it is used to set emissions standards for engines. For example, the US Environmental Protection Agency (EPA) sets g/bhp-hr limits for nitrogen oxides (NOx) and particulate matter (PM) emissions from heavy-duty diesel engines. The European Union has also set g/bhp-hr limits for emissions from passenger cars and light-duty vehicles. In summary, g/bhp-hr is a standard measure of the efficiency of an engine in terms of fuel consumption and emissions. It is an important metric for manufacturers, regulators, and consumers alike, as it allows for the design and evaluation of more fuel-efficient and environmentally friendly engines.

Grams Per Brake Horsepower Hour (GBHP) is a measure of the efficiency of a building’s energy consumption. It is the ratio of the amount of power generated in the form of brake horsepower (BHP) to the amount of fuel used in grams per hour. GBHP is a useful metric for architects to compare the energy efficiency of different designs and materials. It can be used to evaluate the overall energy efficiency of a building and to determine the optimal design for a particular site. By looking at the GBHP of a building, an architect can quickly and easily determine the amount of energy being consumed and how efficiently it is being used.

Masonry is a form of construction which involves the use of various materials such as stone, brick and concrete. Grams per Brake Horsepower Hour (g/bhp-hr) is an important parameter to measure the performance of materials used in masonry structures. It is a measure of the amount of fuel consumed to propel a unit of mass through a given distance. This measure is used to calculate the amount of fuel consumed per unit of work done, which provides a metric for the efficiency of a material in terms of energy use. It is an important metric for architects to consider when selecting materials for their projects, as it can help to ensure that the most efficient materials are used.
