Impact of conservatory as a passive solar design of UK dwellings

Abstract

2The prime goal of professionals in the built environment is to build cost-effective, environmentally sustainable buildings. This work focuses on the viability of passive solar design strategies of conservatories in the UK in mitigating the impact of future climate change. It further shows that passive solar energy utilisation in building design can contribute to the reduction of dwelling energy consumption and enhancement of indoor thermal comfort. Synergetic passive design strategies that optimise solar energy gains through thermal simulation analyses of varying future climatic conditions, occupant behaviour, building orientation, thermal mass, advance glazing, appropriate ventilation and shading, which influence the potential thermal performance of the conservatory, are devised. The balanced energy benefits of reduction in energy consumption through the application of passive solar design principles for space heating in winter and the challenge of reducing excessive solar gains in summer are analysed using the Cibse TM52 adaptive thermal comfort criteria. The results show that judicious integration of passive solar design strategies in conservatories, with increasing conservatory size in elongated south-facing orientation with an aspect ratio of at least 1·67, could decrease energy consumption, enhance thermal comfort and help to mitigate the impact of climate change when the conservatory is neither heated nor air conditioned.

The Impact of Different Weather Files on London Detached Residential Building Performance—Deterministic, Uncertainty, and Sensitivity Analysis on CIBSE TM48 and CIBSE TM49 Future Weather Variables Using CIBSE TM52 as Overheating Criteria

“…In building performance practice, it is imperative to secure reliable formatted multi-year weather files which have been prepared from reliable meteorological predictions to assess the energy performance and overheating risk in buildings [1][2][3][4][5].…”

Overheating assessment in flats with glazed balconies in warm-summer humid continental climate

“…4 They prove that incorporating this kind of passive system in a building can be an effective way to reduce energy demand, both in colder and milder climates. [5][6][7] The prevailing part of such analyses is based on computer simulations, 1,[8][9][10][11][12][13][14] but some are also supported by experimental research and temperature measurements in existing dwellings. [15][16][17][18][19] The most extensive monitoring of flats with glazed balconies was carried out in Finland, aiming at the estimation of their effectiveness in the cold climate of northern latitude.…”

Optimization Analysis of an Energy-Saving Renovation Scheme for Building Envelopes of Existing Rural Houses Based on a Comprehensive Benefit Evaluation

“…By separating outdoor and indoor spaces through additional sunshine rooms, the lower outdoor temperature is buffered through the additional sunshine room. The additional sunshine room refers to an auxiliary space constructed on the outside of a building using transparent materials such as glass [35]. This space is equivalent to adding buffer space between indoors and outdoors, reducing the direct heat exchange between the external climate environment and the building body, reducing indoor heat dissipation, and achieving the insulation effect [36].…”
