What are sustainable HVAC options for your workplace design?

1 Solar thermal systems

Solar thermal systems use solar collectors to absorb heat from the sun and transfer it to a fluid that circulates through pipes or tubes. The fluid can then be used to heat water or air for space heating or domestic hot water. Solar thermal systems can be integrated with conventional HVAC systems or standalone units, depending on the size and layout of your workplace. Solar thermal systems can reduce your reliance on fossil fuels and lower your carbon footprint, as well as your energy bills.

2 Geothermal heat pumps

Geothermal heat pumps use the earth's natural temperature as a source or sink of heat. They consist of a network of pipes buried underground that circulate a fluid that absorbs or releases heat depending on the season. The fluid then passes through a heat pump that either heats or cools the air for indoor distribution. Geothermal heat pumps can provide year-round heating and cooling with high efficiency and low maintenance. They can also reduce your noise and air pollution, as they do not require any combustion or outdoor units.

3 Radiant heating and cooling

Radiant heating and cooling systems use surfaces such as floors, ceilings, or walls to deliver heat or cold to the occupants. They work by emitting infrared radiation that warms or cools people and objects directly, rather than heating or cooling the air. Radiant heating and cooling systems can offer more even and comfortable temperatures, as well as better indoor air quality and humidity control. They can also save energy and space, as they do not require ducts, fans, or filters.

4 Demand-controlled ventilation

Demand-controlled ventilation (DCV) systems adjust the amount of fresh air supplied to the indoor spaces based on the occupancy and activity levels. They use sensors to measure the carbon dioxide concentration, temperature, humidity, or other indicators of air quality and demand. DCV systems can improve the indoor environmental quality and health of the occupants, as well as reduce the energy consumption and costs of the HVAC system. They can also prevent over-ventilation or under-ventilation, which can cause discomfort or health issues.

5 Energy recovery ventilation

Energy recovery ventilation (ERV) systems recover the heat or coolness from the exhaust air and transfer it to the incoming fresh air. They use heat exchangers, wheels, or cores to exchange the sensible and latent energy between the two air streams. ERV systems can reduce the heating and cooling loads of the HVAC system, as well as the humidity levels and condensation problems. They can also enhance the indoor air quality and comfort, as they provide fresh and preconditioned air.
