Adding zones and heating and cooling loads

Sometimes we need to heat and cool more than just one room at a time. This is where the zone function of Revit MEP comes in handy. Once the zones are in, we can allow Revit to analyze the separate spaces as well as the zones. To proceed, we're going to first add some spaces to our model. Then we need to create a space schedule to rename the spaces appropriately. Once the correct names are in there, we'll then add a zone and run a heating and cooling report. To get started. Under the mechanical heading, under HVAC, let's go to one Mec Floor plan.

I want to zoom in on this area right here. What we're going to do is, we're going to add some spaces, then we're going to combine those spaces into a zone. On the Analyze tab, click on the Space button, put a space here, here, here, and then here. Let's hit Escape a couple of times. What I want to do now is I want to create a space schedule. That way you can rename the spaces to reflect what the room name and number is. On the View tab, click the Schedules drop down, and let's select Schedules>Quantities.

In the New Schedule dialogue, let's scroll down till we find Spaces. Once Spaces is selected, hit OK. Under the Fields, lets scroll down till we find Name and then Number. With your Ctrl key, select them both. Now let's just click the Add button. To switch it up, under select available fields from click the drop down and let's go to room. Let's select room name, then room number. Let's add them to the schedule.

Let's click OK, what we need to do now is rename our spaces and our numbers. Let start with the top one, all caps, let's call it office. Let's rename the number to 111. Let's click into the next row, under space let's just select office, and rename that to 112. Let's go to the next category and call that conference. Let's rename it to 114. Now let's select conference from the list.

Let's call that 113. Let's close out of the space schedule. Let's go to our Analyze tab, let's click Zone. Let's click the Edit Zone button. Under Add Space, hold down the Control key, select office 111. Office 112, and conference 114. Let's make sure all four spaces are included in the zone. Under identity data, for the name, let's call this southeast zone.

Let's click Apply. Let's zoom out a little bit. Let's click on Finish Editing Zone. On the Analyze tab, let's click on Heating and Cooling Loads. Here's our building with the four spaces in the zone. The building type we'll keep as Office. As well as the rest of the defaults. Under details let's click on Analytical Surfaces and drill into southeast zone.

Now we can see all of our components as we drill in. We can isolate these areas and just take a look at what we have individually. You can even look at doors. All the components that come from our architectural model, we can now put into this analysis. What I want to do now is click on the Calculate button. This is going to give us a project summary and a building summary. Here's our peak cooling, maximum cooling.

As we scroll down now we can start to look at our zones. Our Southeast zone gives us our area, our volume, all of our data that we would need. In the Southeast zone spaces, we can now see the spaces that are in those zones. If I click on 113 conference, this gives us a summary of this space. Go head and close out of this window. And in the project browser, scroll down until you see reports.

We want to load reports. And here is our loaded report. Allowing Revvit to analyze a baseline report is one of the huge reasons that BIM is taking over the industry.
