As concerns windows facing south barriers on both sides, two shading coefficients must be multiplied. A measured energy rating shall be determined in accordance with Chapter 4 of this Regulation. Part of the accumulated and released heat shall be disregarded, while dynamic effects shall be taken into consideration, empirically determining the gain and loss utilisation factor.

For buildings to be designed, reconstructed or renovated the following output data shall be applied when acquiring the calculated energy rating at the design stage:.

Optical properties of the screen. Procedure for Calculating Internal Heat Gains. If changes have been made to a building in the assessment period, which affect the energy performance thereof for more than 10 per cent, the previously obtained data may not be used for the assessment of the energy performance of the building. 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 of the assessment period.

The following formula shall be used for determining the set-point temperature for heating in one zone calculation:. Precise and reliable meteorological data are necessary for building performance analysis. The influence of the solar irradiation in addition to the temperature of the sun influence shall be taken into consideration when calculating solar heat gains.

Generation of a test reference year for Alūksne, Latvia [2015]

If an assessment is carried out by using the energy accounting, the assessment period shall cover a wide at least month range of the average external temperatures. Indicators required for the calculated energy rating shall be obtained according to the following procedure:.

The quality of a validated data set shall be the balance between the costs for the data obtaining collection and the appropriate accuracy. If a building is partitioned into several zones and the heat flow between the zones is taken into consideration, then also any type of heat transmission including air movement shall be taken into consideration and the calculation shall be performed in accordance with Annex B to Standard LVS EN ISO An assessment period shall be the full number of years.

A system boundary is related to the object under assessment for example, building, building unit, apartment and comprises all elements of the interior and exterior, which are related to the building where the energy is produced or consumed. Q dz,n,j – energy required for cooling in the definite zone in the calculation period j per hour or month Whwhich shall be calculated in accordance with Sub-paragraph 5.

Thermal energy from boiler rooms without cogeneration. If an assessment period is shorter than five years, an adjustment of the energy consumption due to climatic conditions shall be performed. Energy consumption for heating, cooling, heat transmission losses and heat losses through ventilation shall be assessed in accordance with Chapters III, IV, V and VI of this Regulation, taking into consideration internal and solar heat gains and recoverable losses of the technical building system.

When using the steady-state method, dynamic effects, which shall be calculated by using correlation factors, shall be taken into consideration. Predicting performance of a renewable energy-powered microgrid throughout the United States using typical meteorological year 3 data. Specification of Boundaries and Zones of a Building. This allows for assessing also the influence of the building management practice and changes of the occupants’ behaviour. Q apk,ve – total heat losses for heating through ventilation Whwhich shall be determined in accordance with Sub-chapter 5.

If in the course of construction deviations from the initial building design affect the energy performance indicators of a building, then, when putting the building into operation, an adjustment of calculations shall be carried out, taking into consideration the actual properties of the outer building envelope and technical building systems.

Consumption of liquid fuel in the assessment period shall be the contents of the tank at the beginning of the assessment period, from which the contents of the tank at the end of the assessment period have been deducted and to which the amount of the fuel purchased in the assessment period has been added.

Also building envelopes made of polymers and other translucent materials that serve as glazed elements shall be considered to be glazed elements. Climatic data shall be determined according to LBN “Construction Climatology”, using statistical data of meteorological information.

If a burner runs with a fixed output without modulation and is equipped with a burning time meter, consumption of the fuel shall be lnn difference between two readings that have been performed at the beginning and at the end of the assessment period, multiplied by the flow speed in the burner.

Confidence intervals shall be assessed for all the data used.

Generation of a typical meteorological year for Hong Kong. Q apk,n – energy required for heating, taking into consideration “holiday” periods Wh. Total energy required 003-01 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:.

Gross calorific values of fuel shall be determined by using the net calorific coefficients of fuel, multiplying them by the conversion coefficients, which are specified in Table 1 of this Annex. Energy consumption and calculation initial data collected in lbnn assessment period must relate to the equal time periods. E per – amount of the energy carrier that has been consumed in the accounting period of the energy carrier kg, m 3 or Wh.

It shall be used for calculating heat balance in short time periods for example, per hour. Q apk,n,uzt – energy required for heating in a “holiday” period, assuming that the set-point temperature is controlled on all days of the month Wh.

Classification of building constructions. The boundary of an energy rating for energy carriers gas, electricity, thermal energy and water shall be a meter, while for liquid and solid energy resources – the boundary of the storage system.
