One of the most important considerations when it comes to designing your building for optimal thermal comfort in the indoor climate, is choosing an indoor cooling solution that can meet those needs – together with meeting outlined energy efficiency and green building design goals.
Dedicated Outdoor Air Systems (DOAS) are proving a viable alternative to all-air HVAC systems in green building design. They are auxiliary systems designed to supplement the ventilation and energy efficiency requirements of modern buildings. They can be particularly useful as a sustainable design application in humid climates for their ability to improve humidity control. They prove an energy efficient means of ventilation and air conditioning and used in conjunction with radiant cooling systems, they make for a more effective means of indoor climate regulation.
One of the most heavily-weighed decisions when it comes to project planning the green design elements of your building should be the choice between utilising conventional HVAC systems or newer radiant cooling solutions. Due to the size and scale of modern multistory buildings, the heating and cooling systems employed heavily influences the overall energy usage of the building. To meet certifications and standards for green building, energy efficiency should be factored in as a priority element of sustainable building design.
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.
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.
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.
The debate between radiant cooling and forced air is one that has been going on for some time. In fact, at various points in human history, people have had to weigh up the pros and cons of both systems in order to survive scorching summer temperatures.
The building sector is one of the largest consumers of energy globally. In South East Asia it accounts for around 30% of the primary energy demand and 41% – 51% of the operational energy used in a building is attributed to air conditioning and ventilation. Continue reading
