ASSESSMENT OF THE 2016 THERMAL REGULATION FOR AN ALGERIAN BUILDING. CASE STUDY: IMPACT OF WINDOW TYPE, ORIENTATION AND OPENING RATIO ON ENERGY LOAD USING TRNSYS

Abstract

Statement of the problem. The Algerian building sector is responsible for over 40 % of global final consumption and nearly 35 % of the total CO2 emissions. At the same time the energy demand from buildings continues to rise, for this reason in 2016 the Algerian government launched a new version of thermal regulation for buildings. This regulation replaces the thermal ones of 1997 and 2011 introducing more stringent measurement of thermal insulation in order to decrease the high consumption. Overall, this RT2016 aims at reducing the energy consumption in Algerian buildings. This version imposes the requirements for insulation of the envelope, heating and cooling demand, and windows configuration. The window performance is important to the energy consumption in the building; the façade openings have a great impact of the overall energy consumption. The present research investigates the effect of orientation and façades openness and glazing type on global energy consumption in an Algerian building with a different scenario by using TRNSYS software version 16. A series of simulations has been performed in order to establish the optimal window configuration in terms of area orientation and glazing type. This study aims to address the gap between the requirement in the thermal regulation version and the optimal case through a case study for an Algerian building. Results. The methodology is demonstrated by means of a building case. In the first case we calculated the energy demand for heating and cooling based on the window performance standards in the thermal regulation 2016, in the second one we defined the optimal window by TRNSYS simulation which corresponds to the best window design.
