The Heating, Ventilation and Air Conditioning (HVAC) industry has long been dominated by conventional all-air systems. The debate between radiant cooling solutions and forced air systems is one that has been going on for some time.
The indoor environment and microclimate of a building is one of the most important factors that will come to define the success of the building being used for its designed purpose. A modern multi-story office building is of no use for its intents and purposes if it cannot sustain a relative degree of comfort for its human occupants.
Climate Change Stakeholder Engagement Forum took place in Hong Kong Central Government Offices on 12 July 2016. The forum allowed the Government to tap into the views of more than 600 stakeholders from different sectors to facilitate formulation of Hong Kong’s long-term climate strategy. Representatives from Uponor Asia also participated in the forum to gain further insight into the sustainability challenges the Hong Kong faces and to share our thoughts and recommendations with local government.
The factors for designers and architects to consider when embarking on the challenge of green building design are multiplex. One of the most important elements to incorporate into the planning of green buildings is the overall energy efficiency of the building as a functioning, sustainable whole. Once the planned life of the building is understood, investing in the right green design elements is essential.
With the world moving ever more swiftly along with the green revolution, professionals in the construction industry will need to prioritise sustainable building design if they want to stay in business. This means implementing green design elements right from planning to completion, with a focus on minimising environmental impacts and maximising the building’s lifespan.
Buildings account for roughly one-third of global non-renewable energy use. Space cooling through air conditioning is typically provided through electric compressor-driven refrigeration, contributing a significant portion of commercial building energy use with direct and indirect negative environmental impacts.
The next evolutionary step on the path to carbon neutrality is a functioning, super-energy-efficient, 220,000-square-foot office structure that is the largest net-zero energy building in the United States.
Heat transfer occurs whenever there is a temperature difference between two objects, and it continues until both objects are in thermal equilibrium. According to a formulation of the Second Law of Thermodynamics known as the Clausius statement, heat cannot naturally flow from a colder temperature to a hotter temperature.
Over the last decade, South East Asia has seen a significant acceleration in the adoption of sustainable construction practices. Concerns about environmental degradation and national energy security have provided countries like Thailand, Hong Kong, Singapore, Malaysia and Indonesia with enough incentive to establish their own set of sustainability principles.
A study conducted by BCI Asia showed that 90% of all green building projects based in Hong Kong has pursued and achieved certification. This combined with the substantial growth in registered projects with the Hong Kong Green Building Council (HKGBC) highlights the importance and merit architects and owners have placed on sustainable building practices.
