Adequate and complete information will prevent delays in the plan review process. Reviewing a plan and the discovery that required information has not been provided by the applicant may result in the delay of the permit issuance and in proceeding with building construction. The owner or contractor may be required to provide this information before the plan review may proceed. This causes delays because other plans that are in line for review may be given attention before the new information may be reviewed after it has been provided to the Building Department. Please review this document to determine if you have enough information to design your project and provide adequate information to facilitate a plan review. If you do not, it may be helpful to obtain a book titled "Dwelling Construction under the Uniform Building Code". This book is available to you through this department at our cost. Also, please consider using a design professional for assistance in your design and a construction professional for construction of your project.

Aug04 Page 2 of 9 Building Envelope: Spectrally selective windows: The specified windows are spectrally selective Low -E2 units in vinyl frames. The glass coating allows transmission of most of the visible light (unlike tinted windows), while cutting ultraviolet light transmittance by approximately 90%. Therefore, they reduce cooling load from solar gain, increase comfort, and reduce UV damage to furnishings. Furthermore, the coated glazing has superior insulating properties compared to clear glass. Infiltration/air flow retarder (a.k.a. air barrier): The envelope is tightened to a target based on the surface area of the house (including floor slab). The Building America target is 2.5 square inches of equivalent leakage area per 100 square feet of envelope area. The airtightness of these test houses will be measured with a blower door test. The targets are shown in the table below, in CFM 50 (cubic feet per minute at a test pressure of 50 Pascals) and in ACH 50 (air changes per hour at 50 Pascals). Note that ACH 50 is not the same as natural air changes per hour (nACH).

For these homes, we have specified a 90+% AFUE sealed combustion furnace, 0.62 EF power vented hot water heater, and 12 SEER A/C as an option. Duct system: The ductwork system will be located within the conditioned space, with the aim of eliminating duct leakage to the exterior. The ducts should be tested for tightness in the completed house with a duct blaster test. The goal is a CFM 25 (cubic feet per minute at 25 Pascals test pressure) equal to 5% of the high-speed air handler nominal flow, at 400 CFM per ton. For instance, a 3 -ton unit has a nominal 1200 CFM flow, with a 60 CFM 25 goal. The requirement is for duct leakage to the outside, not total duct leakage. Pressure Relief (Transfer grilles): In order to prevent pressurization of bedrooms and depressurization of the main space when doors are closed, pressure relief measures such as jump ducts and transfer grilles are specified. The typical one -inch door undercut does not provide an adequate return path for the supply air, and can result in discomfort and stagnation in closed bedrooms. Another option for return air from individual bedrooms is to use jump ducts to return air to the air handler. Jump ducts through the vented attic are the preferred pressure relief in this design. Jump ducts are the higher -cost but better -performing method; high -low transfer grilles in the wall are lower in cost, but have lower sound -attenuation properties. Your HVAC contractor should size transfer jump ducts based on room supply flows (CFM) and the transfer grille sizing chart (enclosed). The chart shows the relationship between the supply airflow and the required free area to relieve the pressure (to the 3 Pa criteria). Mini Slue Ibpratlm Hansen Construction Analysis.

An outside air duct is run from the outside to the return side of the air handler. The running air handler pulls outside air into the return system. A flow regulator or adjustable damper provides fixed outside air supply quantities independent of air handler blower speed, and the HVAC system provides circulation and tempering. In addition to the flow regulator, an electrically operated damper will be installed to prevent excess ventilation during peak load usage. This damper will automatically close the fresh air duct to prevent outside air from diluting the conditioned air too much. This unit should be available through most HVAC contractors. Continuous running of the air handler in order to draw ventilation air is not recommended. A fan cycling system controller is suggested, to run air handler periodically; it operates the fan only after a selected amount of time following last operation. Furthermore, this system reduces stagnation in the house by providing mixing of house air and controls the electrically operated damper to prevent over mixing. There are several different fan cycling systems available, for example Aprilaire has a Ventilation Control System BSC recommends setting the ventilation level to a rate of 7.5 CFM per person. This will result in flows of 30-38 CFM continuous average. Note that this will not be equal to the flow through the fresh air supply duct, since it is set up to run intermittently. The duct size and AirCycler duty cycle should be set up so that the net average is 30-38 CFM. Mechanical ventilation results in a slight energy penalty; however, it is necessary for acceptable indoor air quality. Detailed loads, yearly energy use quantities, and current utility costs from REM/Rate can be found at the end of this report. MN Mew Mrporatim Hansen Construction Analysis, Aug04 Page 4 o19 Manual J Room Load Calculations To review the individual mom flows for the homes, it is necessary to perform separate calculations that take into account specific loads generated in each room. Manual J is a common method for determining these loads, and in particular Building Science uses RHVAC for this purpose. As well as the takeoff of building areas, volumes, and insulating characteristics, the following assumptions were made: The following building attributes were used; many of them are in the standard Manual J building component list. When non-standard components are used, an explanation follows. This is meant as an example; modify these components to suit your building. • Doors: 11N (Door Metal Polystyrene Core): A standard input; if a different type of door is being used, it should be updated. However, it will have a minor effect on heating & cooling loads. • Walls: 12F (Wall R-21 + W 0513/Ply): A standard input. • Garage Walls: 12F (Partition R-21 +1/2" OSB / Ply): Another standard component. RHVAC calls for manually inputting a modified summer and winter temperature differences, as opposed to the indoor/outdoor temperature difference of 19° F/72° F. The temperatures of 30° F and 50° F (respectively) were used here (i.e., garages are hotter than outside in the summer, and warmer than outside in the winter). However, I would defer to a local engineer if they have a better idea of typical temperatures and conditions in garages. • Ceiling: 16CR-38 (Ceiling R-38 Insulation) at flat ceilings: Standard components • Foundation Walls: Basement: 15B, (Wall 8" or 12" Block + R-8), and Crawlspace: 15A (Wall 8/12" Block + R-11), Standard components. • Basement: Basement Floor 6' or More Below Grade (21A): Standard component; this accounts for heat lost through the sub -grade basement slab and the crawl space floor. Note that the floor above the basement is not insulated; it is between two portions of conditioned space, so is not considered a heat loss/gain component. • Floor: 20P (Floor Over Exterior, Carpet + R-30): Standard component • Windows: Double Pane Low E Vinyl: Non-standard component: these high performance windows have whole -unit characteristics averaging at U=0.33 (insulating value); SHGC=0.33 (solar heat gain coefficient). Custom inputs are required for these windows, to ensure that the characteristics are correct. • People load: Occupants are added proportional to bedrooms: it is the number of bedrooms multiplied by two. People loads are considered 300 Btu/hr sensible, 230 Btu/hr latent. As an example, a three-bedroom house would have 6 people; distributed with 2 in the master bedroom, 2 in the living room, and 2 in the dining room or nook. A four-bedroom house would have 8 people: 2, 3, and 3, in the rooms as above. • Equipment load: Kitchen loads are simulated with the addition of 1200 Btu/hr sensible load. Dryer and mechanical equipment loading is added to the laundry room, at 600 Btu/hr sensible. • Lighting Load: Heat gain due to lights is not typically explicitly counted in Manual J; the load is low enough that it falls within the estimates of a typical load calculation. In addition, high lighting loads are typically not coincident with peak cooling loads (i.e., summer afternoons). However, if there will be significant, high -cycle lighting loads, they should be accounted for. For instance, a model that has many can lights that are on 24 hours a day will require more cooling. • Ductwork load: With the ductwork within the conditioned space, ductwork losses go to zero. ItaSeism Ospr stlor Hansen Construction Analysis, Aug04 Page 5 of 9 • Infiltration: The Building America Program requires an airtightness standard of 2.5 square inches of leakage area per 100 sf of envelope, as verified by a blower door test. In Manual J, infiltration is measured as an ACH (air changes per hour) number. Instead of specifying based on Table 5 (Infiltration Evaluation—"Best", 'Average," and "Poor"), we are specifying 0.1 ACH, both winter and summer. This is roughly equivalent to operating infiltration in houses with measured Building America tightness; this has been verified with tracer gas field measurements with multiple climates and construction types. • Ventilation: Ventilation load is calculated by taking the target flow (7.5 CFM per person) and doubling it, both winter and summer. This is done to reflect worst-case intermittent loading from to the supply -only system with the AirCycler controller. Therefore, a 3 bedroom house should be run at 80 CFM (2 people in master bedroom plus 2 bedrooms), a 4 bedroom house at 100 CFM. Note that the combination of our infiltration and ventilation specifications is a conservative estimate. It has the ventilation system running at maximum airflow, plus infiltration occurring. The supply -only system would put the house under positive pressure, so under typical conditions, air change would occur only through the ventilation system. • Latent Load: Note that latent load is specifically calculated from the people load and ventilation/infiltration loads. The old '30% latent load" rule of thumb is an overestimate, especially in a dry climate such as Glenwood Springs. Furthermore, this estimate is not very logical—increasing the number of windows would raise the latent load in the calculations, which does not reflect what is really going on. The lack of a latent load in CO (note the latent loads are negative) allows applying half of the additional latent capacity to satisfy the sensible load. From these characteristics, the load calculations are as follows for the floor plans evaluated: s 111pli1101 Hansen Construction Analysis, Aug04 Page 6 of 10 • Room Air Flows These loads were calculated with the house in a 'worst case' orientation (with the rear of the house facing west). Along with this information the airflow volumes to each room were calculated, which vary by which direction the house is facing. The following are tables of calculated air flows, averages, and recommended duct sizes and quantities.
