FUTURE MITIGATION OF THE RESIDENTIAL BUILDING HEAT LOAD USING THE PERGOLAS AND DECIDUOUS CLIMBER

Abstract

This paper critically examines the possibilities of combining pergolas and V. Coignetiae as energy-efficient, bioclimatic, green architecture and passive solar systems in the single-family building located in a moderate continental climate zone, i.e. Kragujevac (Serbia). More precisely, the impact of facade wall (without transparent elements) orientation with and without the mentioned measures (elements) on the electricity consumption for space cooling from 1 April to 31 October is investigated. The initial building model was developed using Google SketchUp software and following the Serbian Rulebook on Energy Efficiency for New Buildings. The thermo-technical systems and occupancy were simulated with EnergyPlus software. Based on the simulations conducted and the results obtained, the following main conclusions can be drawn: (1) Moderate continental climate is suitable for implementing the proposed concept; (2) Electricity consumption for space cooling, in the single-family building without energy-efficient, bioclimatic, green architecture and passive solar systems, is the highest when the facade wall (without transparent elements) is oriented to the North (827.25 kWh); and (3) Pergolas and adopted deciduous climber, placed in front of the facade wall (without transparent elements), reduce the electricity consumption for space cooling the most in the case of an Eastern orientation (363.7 kWh).
