Navigation and Practical Access Guide to the Building
Science Hall at the University of Wisconsin-Madison is one of those buildings that looks fine from the outside but will quietly mess with your day if you haven't spent time in it. It sits on the north side of campus near Henry Mall, and it houses a mix of chemistry, biochemistry, and related department offices and labs. The building has been through significant renovation work in recent years, which changed a lot about how it functions day to day. Here's the thing nobody tells you: the main entrance on the south side faces Henry Mall, but most people who work or study there end up using the side entrances depending on which floor they need. The elevator situation is not ideal. There is one main elevator bank, and during peak hours between classes it's genuinely stressful. I spent an entire semester trying to get to a third-floor office and almost always just took the stairs because the wait was eating into my time between meetings.
Science Hall Uw Madison Floor Layout
The ground floor has the chemistry stockroom and some administrative offices. It's also where the public-facing parts of the building live. Move up and you hit the teaching labs, which are the big open spaces with fume hoods and bench seating. These rooms run on tight schedules and the doors are often locked between class sessions. If you're not in a class at that exact time, you won't get in. The upper floors contain more research labs and faculty offices. The north side of the building has windows that face the science Quad, and the south side looks toward Henry Mall. The interior corridors are narrow by modern standards, which makes moving equipment between rooms a logistical exercise that requires planning ahead. I learned this the hard way when I needed to transport a piece of glassware through three doorways and a stairwell during a move, and it took two trips and a cart I had to reserve from facilities. Practical access tip: You need a BadgerID card to enter most interior doors after hours. The building isn't open 24/7 for general foot traffic, even though some research labs have extended access for approved personnel. Check with the department you're visiting before showing up late in the evening.
Building Systems and Things That Break
The fume hood system is one of those things that sounds straightforward until it isn't. The building uses variable air volume (VAV) hoods in the renovated lab spaces, which adjust airflow based on sash position. During the renovation, the old constant volume system was replaced, and honestly the new setup is better but it has quirks. If you set a sash and the airflow indicator doesn't respond within a few seconds, don't just force it. I once had a hood start alarming during an experiment because the VAV damper controller had lost communication with the central building management system. The workaround was resetting the local controller panel in the mechanical closet on the same floor, which took about ten minutes and resolved the issue without calling facilities. The heating and cooling in older sections of the building is zoned by floor, and the zones don't always cooperate. Ground floor and second floor tend to run warmer in winter because they're closer to the main steam supply lines. Third and fourth floors get noticeably colder. If you're spending long hours at a bench, bring a layer. This isn't a new problem. It's been documented in student feedback for years. Near-infrared spectrometer calibration drifted one semester because the HVAC cycling was causing temperature fluctuations in the lab where it sat. The lab manager ended up installing a small room-level thermostat controller to stabilize the environment, and the drift stopped. Something as simple as that matters more than people realize when you're running sensitive instrumentation.

Getting Around Efficiently
If you're new to this building, map out which entrance gets you to your destination fastest before you need it. The south entrance off Henry Mall is the most obvious but also the most crowded during transition periods between classes. The east entrance near the chemistry storage area is less trafficked and gets you closer to the lab corridors on the ground floor. The north entrance near the science Quad is useful if you're coming from the east side of campus and need to reach the upper floors quickly. The stairwells are marked but not always well lit in the older sections. I've seen more than one person miss a step going down during a rushed exit between classes. The renovation improved lighting in common areas, but some of the corridor sections still have bulbs that go out and don't get replaced promptly. For directions, the campus maps online are generally accurate, but they don't capture the reality of which doors are propped open and which are locked. The best approach is to check the specific department webpage for the room you need, and if you're visiting for the first time, arrive fifteen minutes early to locate the right entrance and stairwell. That buffer time saves you from stress later.
There's also a basement level that contains mechanical rooms and some storage. It's not accessible to the general public, and the stairs down from the ground floor are narrow and steep. Don't wander down there unless you have a reason and someone with you. The building has good natural light on the north-facing windows, which is actually preferable for certain types of photo-sensitive work, but the afternoon sun hits the south-facing labs hard in the summer. Blinds are available but some of them are stuck. If you're assigned a lab space there, test the blinds on day one and report any failures to the lab manager before the heat becomes a problem.
