Executive Summary . The contents of this report are building load and energy estimates as well as an estimate of the annual energy consumption and operating cost of the Lehigh Valley Heritage Center. The calculations were evaluated by both simple “hand calculations” and by a computer-based method using Carriers Hourly Analysis Program 4.10. The calculations are being used to determine whether the design conditions will satisfy the loadings directed on and located within the building. The “hand calculations” were performed on Excel, using basic calculations to determine the electrical, occupant, fenestration/envelope, and outdoor air loadings. Fundamental knowledge of heat transfer and approximations were used in the determination of the heat gain into the building. The Lehigh Valley Heritage Center is located in Allentown, Pennsylvania. The ASHRAE Handbook, 2001 Fundamentals, lists the design conditions for outdoor air temperatures of cities/towns located throughout the world. For Allentown, PA, the outdoor air temperature for design in the winter time is 5 Degrees F, (99.6% annual percentile) while the outdoor air temperature for design in the summer time is 90 Degrees F (0.4% annual percentile). The range of weather can greatly affect a buildings heat loss or gain by means of temperature gradients, convective winds and/or radiation effects through glass areas. Internal sources of heat are of high importance too, especially with the growing and expanding era of electronic devices and hardware. Specific rooms of the Heritage Center will house computers, networking lines, security devices, and a vast majority of lighting. The Heritage Center will also be a host to many visitors which contribute sensible and latent heat to be conditioned by the building system(s). Below is a summary of the calculated, designed and simulated data for the load analysis. Cooling ft2/ton: Total Supply Air cfm/ft2 Ventilation Supply cfm/ft2

Simulated 207.52 1.42 1.44 An annual energy consumption was computed using user written equations and by Carriers analysis program. Because the building is not yet constructed, there is no utility bill or energy consumption summary. Through online resources, the monetary values of utilities from PP&L Co. were roughly estimated to be $6.28/Dekatherm for natural gas and $0.0775/kWhr for electricity. The electric rate was given via phone conversation on Monday October 29, 2003, by a commercial representative of PP&L Co. for a mid. size, secondary service, GS3 rate building. No demand charges were given, nor inflation or tax rates. An assumed tax rate of 5% was used in the Carrier program. No energy analysis was performed by the mechanical engineer during the design phase. The building was confirmed to adhere to PA Labor and Industry Act 222, which is a predecessor of Standard 90.1-1999. Building load calculations were performed using Elite’s CHVAC program, although. The simulated vs. designed cost is: $33,148 vs. $51,729, with a price per sq.ft of: $1.36 vs. $1.86. Clearly the simulation data is more accurate because it accounts for solar loads, below grade walls, duct leakage, pipe leakage and efficiency.

Design Load Estimate

Lighting Load estimates were performed using an Excel spreadsheet with basic psychometric and heat transfer

equations. First, the spaces were put into the spreadsheet along with their corresponding square footage, which was retrievable from the first technical assignment. Each room contained a designed amount of light represented in Watts, which was taken from technical assignment 2a, and placed in the corresponding spreadsheet. Task lighting was only given in special spaces, such as the offices, reading room and the work stations. These rooms will have lamps for individuals to use on their desks to better illuminate their workspace since it is at a more isolated spot in the room(s).

Equipment Next was the determination of equipment in the spaces. Equipment in this case does not represent the mechanical equipment of the building but instead copiers, computers, printers, coffee machines, facsimile machines, etc. According to ASHRAE Fundamentals 2001, there are several basic W/ft2 estimates one can use for the different types of equipment in the space ranging from 0.5 to 2.0. In the typical office spaces on the second floor, a value of 1.5 W/ft2 was used. In other spaces, such as the reading room, processing room and school program, a value of 1.0 W/ft2 . And in some extreme cases such as the copy room, typical values for large scale copiers were used to estimate the equipment load. The values for the copy equipment also came from ASHRAE Fundamentals 2001, which were just estimations of the pieces of equipment contained in those rooms. After the lighting and equipment loads were computed, the resulting loads were added together for each space and converted to units of energy, Btu/hr. This step now makes finding the volumetric flow rate of supply air much easier as the estimate process continues on.

Occupancy The occupancy for each space was determined from the design plans, as well as the first technical assignment. It was assumed that the people were in a relaxed pose, not doing any significant physical work, which would increase their metabolic rate. The typical design factors for sensible loss heat and latent loss heat are 245 Btu/hr person and 205 Btu/hr person respectively, given in the ASHRAE Fundamentals 2001. The full load occupancy was used in order to account for the worst possible situation regarding heat pickup. Although the latent heat is included in the spreadsheet it should be noted that it is not included in the calculation for volumetric flow rate of supply air.

Fenestration and Building Envelope Typical walls and windows were chosen to make the estimation of the building load as simple as possible. The values are very similar to the values specified in technical assignment 2a. Each space was evaluated to determine wall and window area that would allow heat gain and loss. A typical wall U value is 0.047 Btu/hr F ft2 while a typical glass U value is 0.452 Btu/hr F ft2 . The wall values were estimated using the Carrier HAP program. The general formula used for calculating the heat transfer through the wall is:

Q=UA (Tout-Tin) {Btu/hr}

Srebric which is positive for heat gain and negative for heat loss. This equation was also used for the glass and roof areas. Please note that only the height of the wall extending from the floor to the suspended ceiling were used in the calculations for the wall areas while the entire second floor was calculated as having a heat gain/loss from the ceiling.

Supply Air Calculation and Ventilation rate After the lighting, equipment, occupant and fenestration calculations have been processed; they are all added up (Btu/hr) and placed in the given equation below to calculate the supply air in scfm:

Q=1.8*scfm*(Tout-Tin) where scfm=Q/ (1.8*(Tout-Tin)) This is the amount of air being brought in at temperature Tin that will condition the space according to the amount of energy being emitted. The ventilation rate was difficult to determine since the ventilation cfm were not marked on the plans. As a general rule of thumb, a value of 20 cfm/person was used to determine the minimum ventilation rate for the spaces.

Design Air Conditions According to the ASHRAE Fundamentals 2001, a building located in Allentown, Pennsylvania will have a heating dry bulb of 5 degrees F for an outdoor air design temperature (99.6 annual percentile) and a cooling dry bulb of 90 degrees F for an outdoor air design temperature (0.4 annual percentile). The cooling dry bulb temperature was used as the outdoor air temperature, while a dry bulb temperature of 75 degrees F was used for the indoor air design temperature. This basis was used on all calculations involving temperatures and temperature differences.

Comparison of Calculated, Designed and Simulated Data

Simulated Data can be found in Appendix A while calculated data is the link Load Calculation Spreadsheet (due to size). The following table will compare/contrast the different values given for the building load conditions. Cooling ft2/ton: Total Supply Air cfm/ft2 Ventilation Supply cfm/ft2

Calculated 915.38 0.809 0.359 Designed 290.5 1.053 0.274

Simulated 207.52 1.42 1.44 There is some discrepancy on the square footage being evaluated. The simulation data does not account for all space in its calculation. It tends to leave out about 6000 square foot of space, while my hand calculations leave out about 4000 square foot. These discrepancies are caused by program/human error. Wall thicknesses can also leave out a considerable amount of space if they are not accounted for properly. Other factors that cause fallacious values are the fact that the hand calculations do not account for the solar angle, wind speed or even a ballast factor for the lights in energy production. The importance of the solar gain is crucial because it is a large contributor of envelope loads. The values for the Total Supply Air seem to be the most accurate of all three

Srebric methods of calculation. The Cooling column is mostly off because of an error or the fact that no-one has ever been in it just yet. The Ventilation Supply is slightly off because of user input and the fact that the simulation data is always putting out 100 percent outdoor air.

Annual Energy Estimate Starting the annual energy estimate contains the first steps of the design load portion. A spreadsheet was set up according to the weather data retrieved from Bin Maker Plus. The weather data contained dry bulb temperatures, hours those temperatures were met, humidity ratios and enthalpies for specific times during the months of the year. First the humidity ratio at the given temperatures is calculated using the equation:

RH= (i-(0.24*t)/(1061.2+0.444*t))*7000 {lbmv/lbma}

Where i = enthalpy Btu/lbm t = temperature F

Outdoor Air Load

The second step is to figure out the outdoor air load, both sensible and latent. This is accomplished by these two equations:

Qsensible =1.08*scfm*(Tout-Tin) {Btu/hr}

Qlatent =0.68*scfm*(Wout-Win) {Btu/hr}

Where W: humidity ratio

Occupancy Load After calculating the outdoor air loads, calculate the occupancy load using the same basis as above in the

design estimate with 245 Btu/hr*person sensible and 205 Btu/hr*person latent. Multiply these terms by the number of people to get a total Btu/hr. After determining the latent load of the people, add it to the latent load of the outdoor air. If the answer is negative then the outdoor air cannot do any latent conditioning and a zero should be put in place of the negative number.

Qlatent total = Qlatent people + Qlatent outdoor Qlatent total >= 0

Lighting and Equipment Load

This process follows the exact same process as the design estimate, except at the end it needs to be multiplied by the number of hours at that temperature to convert it into kWhr.

Overall Building Load

This process follows the same steps as the design estimate. The equation is as follows:

Q = UA (Tout-Tin) {Btu/hr}

Where Tout is the Bin temperature

Equipment containing fans and pumps Equipment containing fans as well as pumps connected to the chilled water system must be converted

into a heat source. For the fans contained in the air handling and roof top units, the horsepower of the motors that drives the fans was given, therefore a simple conversion factor of 0.746 multiplied to the horsepower converted it to kW. After converting it, multiply it by the number of hours that that temperature occurred so that the final units are kWhr. The pumps were converted in the same fashion since their horsepower was also known as well as the hours of the temperature occurrence.

Chiller The chiller is selected by adding up all the loads calculated except for the pump loads. One must be

careful to convert all units of load to a similar unit in order to add the values. Once the chiller has been sized, one can proceed with solving for the total load. IMPORTANT: the chiller cannot have a negative value, if it does, the value assigned to it is zero. If the chiller shows a negative value, it means it is not running and will be shut off, even though the pumps might circulate the water for freeze protection.

Previous Energy Analysis

There was no previous energy analysis on this building, according to the engineer, Matthew Lesoine. Mr. Lesoine explained that the building was confirmed to adhere to PA Labor and Industry Act 222, which is a predecessor of Standard 90.1-1999. Building load calculations were performed using Elite’s CHVAC program, although.

Utility Rates Utility rates for the Heritage Center were estimated from rates on-line and from a conversation with a PP&L Co. employee. A basic price for natural gas was found to be $6.23 per Dekatherm from PP&L Co. A basic rate for electric for a mid size, secondary service, GS3 rate building is $0.0775 per kWhr. This value of electricity pricing was given by an employee of PP&L Co.

Schedules

Two basic schedules were used in the program. One was based on the time of the day and the percentage of occupants in the space during the week. That schedule was modified so that no one was in over the weekends or from 8pm-6am during the week. The other schedule was a thermostat schedule based on occupancy (either occupied or unoccupied). This schedule follows the same time frame and occupancy as the first schedule, no one in during the weekends or from 8pm-6am during the week.

Conclusion Based on the results of this paper, a simulated building can prove to be a great benefit when asked about systems, utilities and loads on buildings. It is more accurate than doing it by hand and much faster. The only drawback is human mistake, which can affect anything at anytime. The simulation data accounts for solar angles, below ground wall structures, and most equipment. Although not all systems can be accurately simulated, it proves to be a time saver and provides general ballpark figures. I would be more comfortable with reading the simulation data rather than the hand calculations.

The simulation data seems fairly reasonable based on the assumptions of the data being placed in the computer program. Although the utility information was not 100% accurate, the program still responded to the inputs. The average value of $1.37/sq.ft seems a little low, but then most of the building is storage anyway, plus the fact that my schedules are telling the program that no one is occupying the building at certain hours.

Also, the simulation data provides the closest estimate to the design of the building, which is a

reassuring factor that the building loads were accounted for and that any mistakes between the programs used are either similar or negligible. As the building progresses more towards bidding and construction, it will be easier to talk to representatives, workers and owners about utility pricing and similar buildings that would share a similar utility usage. Following up on this idea is important to future evaluations of this building, considering a re-design as well.
