S1.0 INTRODUCTION

The Calhoun Lofts have reached 5 years of useful service to the University of Houston but in Fall 2015 it was time for the lofts to go through some final exams of its own. The importance of these tests are to inform the occupants, architect, and University staff about the buildings energy performance and the overall satisfaction of the occupants with the buildings design and systems. Kirksey Architects, who designed the Calhoun Lofts, measured several sustainable metrics to ensure that the building performs as originally designed. Conducting the post occupancy evaluation enables the University to determine deficiencies within the lofts in regards to energy usage and sustainable practice of the building. It will also inform the architect of design successes and deficiencies through surveys and detailed measurements and analysis.

This analysis will determine if any deficiency in the design and layout within the Calhoun Lofts are present and will provide the University with clues about what the sources of the problems could be. The process of analysis was through

observations and measurements will determine what systems, if any, are not allowing the building to perform to its full potential so that it is not costing the University inexcessive energy usage and costs. The importance of the POE within the sustainable building process is that it shows how the building performs and whether it performs how it was designed. If the building is not performing as expected this report allows several invested parties to take this data and make decisions that will improve the buildings performance and influence future building design and implementation.

This report contains the results of the opinion survey filled out by over 100 occupants and workers and contains measurements of daylight levels (lux), acoustic levels (dBs), temperature (F), Relative Humidity (%), CO2 (PPM), Formaldehyde (PPM), and Particulate Matter (PPM). The team conducted measurements over a period of 2 days. The process involved multiple measurements in rooms chosen based on their location of the building.

You can hear too much from up above neighbors. I can hear them simply walk or drop items and I assumed that the cement would stop the noise transfer. The acoustics of the lofts are terrible. I cant play music or have a conversation in my living space without having half of the hall hear it. Im not sure if its the walls or the door, but the sound travels right through it. Terrible acoustics I would say. I cant have 4-5 people over and have a conversation with them without having to be concerned with our voices or conversation being heard outside in the hall. and the AC is too loud, Wall is too thin, I can hear noises loud enough for me to hear in my room but its not loud enough to hear in the hall so its hard to make a complaint The noise is pretty bad, As I can always hear my roommates TV and when they play video games. the furnished rooms should provide smaller but more silent refrigerators because the current ones produce lot of noise. I Another problem with the parking space directly located in front of the apartments windows is that it creates additional noise. Which is, due to the fact that the a rather busy road is located on that side of the building, sometimes annoying, especially if a car alarm goes off directly in front of the window or the car honks when it is locked. I cant hear my neighbors but I can here every single word my roommate says if they are in the living room, bathroom area, or the kitchen even when my door is closed, and I can hear my room-mates tv very clearly if their door is open, even if its not loud, even if my door is shut. The floors are horrible. I can hear people walking in heels from the floor above me when the refrigerator operates, it is too loud!!! You can easily hear when someone drop or makes a lot of noise above or below the space. Not sure what wall assembly composes of but they dont prevent much noise from traveling between a neighboring dorm room. You can easily hear when others are having a conversation. Would be a perfect place to live if given more attention to noise control. Concrete floors and ceilings can be aesthetically pleasing however are horrible with noise. People complain about me being loud when Im not. Fix the sound barrier I can hear everything in the hallway from inside my room Rooms echo my roommate and I can constantly hear the room next to us just talking and in the hall too much reverb from concrete flooring The walls are very thin, I could hear noise from peoples rooms all the time. and hear everyone, Horrible thin walls!!! All walls SUCK. very thin hear everything thin walls

I am not a big fan of the light fixtures for I am struggling to obtain adequate light once the sun goes down,v would love to have more lighting in my room to allow more comfortable living situation Because the north wing of the first floor is directly located next to the parking lot of the law center, in the evening and the night there is plenty of light due to the street lights illuminating the parking lot but also especially due to cars parking in front of the apartments windows while leaving their headlights on. As the window shades do not fully block the light from coming into the room, the light sometimes makes it hard to fall asleep. Need more light My room is in the alley of the building (W913) and is VERY dark. more lighting, need even more lighting in the bedroom living room lighting needs to be better for night time The light in the rooms is bad. I have to bring lots of lights to make the room brighter. have brighter lighting in living room

The building temperature is cold in some areas, especially the center side. I hope it will be less cold a little bit. the 6th floor glass study lounge has an AC issue we would like to control the temperature in the study rooms. The study rooms are too cold Certain hallways are freezing Since everything is concrete it makes the room feel kind of cold roof indoor area is FREEZING I do not appreciated not having a more customizable thermostat.

corner room/study lounge since my floors study lounge is humid and uncomfortable. The air filters get easily dirty and makes for the suite to be dusty and filled with germs, which is why Im constantly sneezing whenver im in the suite. t would be nice to have a vent in the bathroom, in order to prevent moldy towels It gets really stuffy inside the building, especially the loft, if theres a way for some fresh air to come in, thatd be awesome. Its too dry in here which makes it depressing. Strong odors from trash rooms. The trash rooms leave an awful smell in the hallways. The only issue I have with living here is the ventilation. My room tends to get stuffy and I had to buy a portable fan. Do something about the weed smell Also vents above stove to no work adequately. too much dust in rooms; is it the air vents. Air quality not very good odors I wish could open a window. circulate air out of the building air movement gusty in living room area can smell everything and hear everyone Poor circulation of vents in room. rooms need ventilation!!!!! open windows or something. air is so stuffy in rooms... a/c in on but its not fresh and unable to access outside air from room. stuffy/ stale air

AIR QUALITY COMPLAINTS

WATER COMPLAINTS

I do not like the constant water outages. It would be nice not to have a power outage or water outage once a week There have been al-most five water outages in the past couple of months The water is always dirty and not minimally clean enough to put in a purified water system like a PUR water filter. the other day, the maximum water temperature had dropped significantly. Also, since the water cut-off There needs to be less water outages. our water is shut off at least once a week Less water cuts! fix water no drills I dont like that the water doesnt work/ outages

My measurements were taken on a temperature, humidity, and CO2 multi-meter. I was the first person in the room due to the sensitivity of the CO2 detector. If many people entered a room and began breathing heavily then the measurements would be less accurate. I placed the multi-meter on a table, chair, window sill, or on the floor and stood away from it while it normalized the readings. In only a few places did the CO2 measure above 1000PPM. Certain factors in the rooms can add to an elevated CO2 reading.

Typically in rooms where temperature were higher (and the thermostat was set higher than normal) affected the rooms CO2 levels. This is possible because the AC was not running and room air is not being refreshed. This allows for the buildup of CO2 due to lack of air changes made by the system. Levels of CO2 were not considered hazardous until past 1200 PPM. A solution to high CO2 levels would be to allow for operable windows in the building. This would allow occupants on more temperate days to maintain temperature but refresh the air in their room. Humidity was not out of normal range by building standards.

I took measurements for solar illumination as well as acoustics. For the solar illumination, I used a light meter, and placed it at desk top height to determine the amount of useful daylighting. All artificial lighting was turned off and blinds were raised, and measurements were taken in multiple locations to examine the spread of daylighting throughout the space. Acoustic levels were taken once per suite with a decibel meter set to pick up lower constant vibrations.

The light levels distributed fairly evenly throughout the rooms except for rooms with over head cabinetry; these rooms were significantly darker. We discovered that the vast majority of students kept their blinds down because of unfavorable amounts of sunlight during the mornings or evenings. Acoustic levels varied from room to room, but outside noises were easily heard through walls and doors. The leakage of sound is a common complaint from occupants.

To the left are images taken with a thermal camera. Theses images reveal many issues with the design of the buildings systems. The building performs very well in terms of thermal comfort and energy sustainability, and although it is ahead of the curve in many respects, issues are abundant.

In images 1-6 one can see the effect of thermal bridging through the building envelope. The warm bands are structural members absorbing heat from the exterior and transmitting the heat to the interior. A temperature difference of 5 to 10F occur in these instances. This is due to the use of no continuous insulation within the envelope system.

In addition to the visible thermal bridging from structural members, images 4-5 reveal an instance where the insulation either collapsed or was not included during construction.

Image 7 shows th heat from uninsulated hot water pipes radiating into the air around it.

Images 8 and 9 are hard to dissect because of their unexpected nature. This is an interior wall which either has a problem within the wall assembly or in the room on the other side. It is likely an electrical wiring issue which is causing the 10F difference.

Images 1 & 2 show cold spots which are likely leaks from pipes. The first image occurs next to a sprinkler head which may be damaged. The second image shows moisture on the wall coming from the floor above where a large water leak happened.

Images 3 - 9 are more examples of thermal bridging along structural members and window frames.

Images 1 - 6 are more examples of thermal bridging along structural members and window frames. Image 6 shows how thermal bridging can also work in the opposite direction. After a cold night, the warmth within the room is escaping through the same structural members causing a difference of -5 to -7F.

Image 7 shows the effect of the sunlight on the exterior of the building causing a difference of over 30F. Similarly, images 8 and 9 show the effects that sun light has on the roof terrace.

S5.0 Conclusion

Overall, the building performance analysis was verifiably good but several small issues are needing to be addressed. This will be brought up at a future meeting with Kirksey Architects and student housing on campus. We learned the steps of how to conduct a proper, large scale post occupancy evaluation. Kirksey Architects is the only firm in Houston who conducts post occupancy evaluations and this was the most complex building that they have ever analyzed. It was a pleasure for us to work with professionals and discover what design schemes worked and which ones did not. It was also very interesting to interact with building occupants and explain what we were doing there.

The future of sustainable building performance will benefit greatly by using post occupancy evaluations to determine effective strategies for sustainable system implementation. By utilizing the data that we have measured, Kirksey Architects will know how to build a better, more sustainable dormitory in the future. Hopefully, Post occupancy evaluations will become an important part of the future of the built environment and bring a conscious effort from design professionals to make their buildings more sustainable.
