Events2HVAC is a software application. Typically, no HVAC control hardware, electrical wiring, or panel mounting is needed to interface to existing compatible systems. The software will need to be hosted on a Windows server or PC, but typically these resources are already available in your facility.
Starting in Feb 2016, we will offer various PC and server platforms that are pre-loaded and configured for Events2HVAC.
If your facility doesn't have an HVAC system that can talk to Events2HVAC, some hardware upgrades or add-ons to your HVAC control system will be necessary. There are many gateway and protocol converter options out on the market today that may work with your system. Your HVAC controls contractor will be able to give you some ideas on upgrading your system.
With the release of version 1.4 of Events2HVAC, the new Professional edition of Events2HVAC will allow than one type of system or multiple instances of the same type to be queried by a single instance of Events2HVAC. For example, your campus might be using one system for academic schedules, another one for the Student Union, and internal MS Exchange/Outlook for meeting rooms. All systems can be synced to your building automation system.
Events2HVAC requires that a supported room scheduling system is in use at your facility. See our list of supported event providers. If your system is not listed, let us know what you are using and we'll look into the feasibility of creating a new event provider connection. If your organization uses Microsoft Exchange Server for email, you may already have the capability to interface to Events2HVAC just by scheduling a room resource in an Exchange Outlook calendar.
Events2HVAC can also allow fixed equipment schedules, building schedules, and other shared space schedules that would normally be set in the HVAC system to be moved up to the reservation system for a single point of control.
Yes, it is possible to setup the software with an internal team. Events2HVAC is an off-the-shelf solution to HVAC integration. However, when you are dealing with connecting multiple systems together, a solid knowledge of how your HVAC control system is networked, basic IT skills, and some troubleshooting will be necessary for implementation.
It is highly recommended to get your local HVAC system representative in the discussions because they may need to enable certain features in the software or they may provide some value insight into how the integration should take place.
For implementations of more than 100 rooms, it is recommended that you schedule a professional setup by Streamside Solutions.
Currently our licensing is a one-time fee. There is an optional maintenance plan to continue receiving updates and support after the first year of purchase. If you are interested in a monthly pricing model to reduce the up-front cost, please contact us.
The cost for a site license is based on how many types of interfaces you will need (BACnet, Net/X, etc.) and the total number of UNIQUE rooms from your event provider that you will need to control. The more rooms you purchase, the lower the cost per room. Please contact our sales team for a specific quote.
Some customers have seen 100% ROI in less than six months. Your ROI will depend on a number of factors in your facility.
If your rooms are scheduled based on building occupancy (i.e., if the building is open, all rooms are comfortable), changing to room scheduling control based on actual events has the potential to save on energy costs. Your actual savings will be based on the occupancy rate of the rooms and the operating cost for the HVAC in those rooms.
If you are currently manually scheduling HVAC equipment based on room/event schedules, then you will have less energy savings and more labor savings when using Events2HVAC. You will no longer need to get schedules from the room scheduling software and enter data into HVAC control systems.
Other factors that will affect ROI are weather, human behavior, and the types of mechanical systems in your facility.
There are many grants, rebates, tax incentives, and financing options available at the federal, state and local levels. In addition, some utility companies offer “on-bill financing,” which allows qualified energy-efficiency projects to be financed through the utility company, with the energy savings actually paying off the facility upgrades over time. The Database of State Initiatives for Renewables & Efficiency (DSIRE) is an excellent place to begin researching available funding options.
You need to count each room that you schedule in your room scheduling software as a separate room. HVAC equipment, such as the air handler in this case, will then be mapped to multiple rooms. But each room that is separately reservable in your room scheduling software needs to also be separate in Events2HVAC.
You can create "spaces" in your room reservation system for these areas and reserve them like any other space. Once the spaces are defined you can map those spaces to AHU's, lighting zones, building card key access, etc.
For office areas that have multiple VAV's serving the area but no reservable rooms, create an office area space and reserve the space for the daily office hours. Assign the office space to multiple VAV's in Events2HVAC.
If you want to start the building AHU whenever any space in the building is in use, just map all reservable spaces to the AHU in EventsHVAC.
Using the new zone action triggers, you can also trigger large AHUs on the first event start of the day and on the last event stop of the day. This will prevent on/off cycling of large AHU's throughout the day and also dynamically adjust the building occupancy based on all the events happening in the building each day.
Absolutely. You can always control your HVAC systems the same way you always have in the past. Events2HVAC sends commands to your equipment typically at a higher priority. Either release the priority and allow your previous scheduling methods to take place or just do an operator manual override on the point.
In the event that an Events2HVAC command fails to command the equipment, an email message will be sent immediately to someone that can respond to the missed schedule. You can select who receives those important emails.
In addition, Events2HVAC will automatically begin to attempt to re-sync the state of the room periodically until the zone is returned to the correct occupancy state.
Occupancy sensors are effective with lighting only because it is a reactive technology. They have no way of knowing when the meeting will be occurring so it cannot pre-start the HVAC to make sure the room is comfortable for the meeting not 30 minutes into the meeting. They obviously can't be used unlock any doors either.
Also, if the occupancy sensor has a long off delay, then you are also keeping things on longer than is needed throughout the course of the day.

No. Events2HVAC is an interface between the two systems. When properly setup, Events2HVAC runs transparently in the background automatically scheduling your systems based on booked room schedules.
