The level of liquid fuel in a tank shall be measured at the beginning and at the 003-001 of ,bn assessment period by using a calibrated scale. Consumption of solid fuel shall be the weight of fuel in stock at the beginning of the assessment period, from which the weight of fuel in stock at the end of the assessment period has been deducted and to which the weight of 00-301 purchased in the assessment period has been added.
Verification of Energy Performance Indicators. The carbon dioxide CO2 emission factor comprises all emissions of carbon dioxide CO2which are related to the primary energy consumed by a building. If heating is irregular or switched off, the influence of the building thermal inertia shall be taken into consideration separately.
The gain utilisation factor for heating shall be determined by using the following formulas:. User Account Sign in to save searches and organize your favorite content. Adjustment of energy consumption due to climatic conditions shall be calculated in accordance with Paragraphs 47 and 48 of this Regulation. The actual efficiency of planned energy performance improvement measures shall depend on the actual utilisation of a building.
Energy Conversion and Management. Hot water consumption data for buildings for which an individual meter has been installed shall be obtained from the difference between two readings at the beginning and at the end 03-01 the assessment period. Conversion coefficient from net calorific value to gross calorific value.

A s,k – surface k with a definite orientation and slope angle effective collecting area in the relevant zone m 2which shall be determined in accordance with Paragraphs glazing and nontransparent building elements of this Regulation. Latvia State Standard Switching off of the thermostat may not be applied for lowering the internal temperature, because it depends on the building inertia heat release from the building.
Energy system losses shall include ,bn losses of the building heat due to uneven distribution of the room temperature and insufficient temperature control. Llbn energy required for heating and cooling for the definite building zone shall be calculated by adding up the energy calculated for the period in accordance with Paragraphs and of this Regulation, taking into consideration a possible load for different heating or cooling parts:. Influence of the solar irradiation to the temperature of a space affected by the sun shall be taken into consideration when calculating solar heat gains.
The quality of a validated data set shall be the balance between the costs for the data obtaining collection and the appropriate accuracy.
Conditions for Calculating Solar Heat Gains. Generation of a typical meteorological year. Since meteorological conditions vary significantly from year to year, there is a need to create a test reference year TRYto represent the long-term weather conditions over a year.
