We at ACI Mechanical solve cold office worker problems for our contractor and owners all the time. Here are 3 tips to make a difference for cold work spaces.
- Change the airflow patterns of diffusers and grilles
Many ceiling diffusers or grilles have the ability to be adjusted or closed down. Many designs have maximum airflow rates that are over designed for actual building usage. Facility engineers (or you with a ladder) can reduce the total airflow directed toward occupants. Change the diffuser from a fixed style to adjustable to have a choice.
2. Install VAV Diffusers to control local zones without extra wiring
We installed a 10″ neck Acutherm Thermafuser in a small conference room at ACI Mechanical in Seattle, changing the room from freezing cold to a perfect 72 degrees. It took a ladder, a new Panduit strap to connect the existing flex duct to the new diffuser, and an Thermafuser to solve the problem. It was a 10 minute installation, before picture shown:
3. Use Preheat strategies on thermostats and building controls for morning warm-up
We use our Verasys building control system by Johnson Controls to preheat the building at 5am, before the first worker arrives at 5:30am in Seattle. This gives the three rooftops the ability to “catch-up” from a weekend of unoccupied setpoints.
Changing the way air flows in a building can make a difference for occupant comfort all year long. It is worth the time and effort!
