While the initial cost of designing and developing a green building may not be cheap, studies have shown that green buildings may eventually garner higher valuations in the real estate market.
Energy-efficient design need not be complex. There are numerous opportunities to integrate sustainable practices and designs into any building. The Centre for Sustainable Energy Technologies (CSET) in Ningbo, China
, for example, employs unique under-floor heating panels that use geothermal energy to heat and cool the building interiors according to the season.
For developments in humid climates, natural ventilation and passive cooling are the most efficient solutions to enhance thermal comfort. In an article titled Natural Ventilation for Passive Cooling by Means of Optimized Control Logics by Rinaldi et al
., according to the ASHRAE 55 thermal comfort theory
, the optimised control logics in natural ventilation results in a reduction of overheating and discomfort, as compared to ventilation only for indoor air quality at fixed hours.
It is also found that when a passive cooling system is combined with active cooling, energy demand for cooling is reduced. The findings show how the proposed optimised control logics increase the ability of natural ventilation to boost building energy and thermal performance by combining/replacing traditional efficiency strategies.
