1. Introduction In terms of urbanization and development, Montreal is one of Canada’s oldest cities with an everyday growing population. With many residential buildings and houses built in the 1950s, an issue under concern is rising: Retrofitting the buildings to comply with today’s building standards and codes as economically and ecologically as possible. Another issue is also underhand and it is climate change. Greener areas in the cities are becoming less common and housings, businesses and highways are popping up in underdeveloped towns. The rising temperatures during the summer have led to the Heat Alert and Response System in buildings due to urban heat islands. The Health Office of Quebec initiated this system because many older buildings do not have an air conditioning or mechanical ventilation systems and its residents are prone to many health issues. The system estimates indoor thermal characteristics of a building with respect to its building materials, the temperatures, outdoor issues etc. 1.1 Scope In this project, I will act as the HOQ and using Matlab, determine the temperature distributions through each wall and the indoor temperatures of a 3 story residential building in Montreal. The intention and thought process behind modeling this building is designing it for the worst possible case. Meaning using low efficient building materials, low performing windows, temperatures recorded during heat waves and assuming no air conditioning or ventilation system. 1.2 Objective To predict the hourly room air temperature in consideration with various real life factors. (Plotted on graph) To predict hourly temperature distributions in the north, east, west and south walls and in the roof all while neglecting the thermal mass of the building itself. (Plotted on graph) To take into consideration estimated heat gains and losses from:
-‐ Solar radiation -‐ Temperature difference
3
-‐ Heat generated by occupants -‐ Air exchange
To take into consideration calculated heat gains and losses from:
-‐ Solar radiation intensities on different surfaces -‐ Ambient air temperatures -‐ Heat gains from the source in the room -‐ Air exchanges

1. Methodology 1.1 Building Considerations 1) Building Location: The building must be of a high construction density built in Montreal. Therefore we will use building materials such as high-‐density insulation, brick or concrete exterior and standard gypsum board. We will consideration the month of July since it has the highest recorded temperatures. We must omit all wind sources but take into consideration heat emissions from surrounding buildings which. This type of heat will come from convection from the HVAC systems of the surrounding buildings. 2) Building System: For this project, we will consider the building with no air conditioning or mechanical ventilation whatsoever. This will force us to find an optimal solution in the most severe conditions and we can later add HVAC as improvements if needed. 3) Building Envelope: For the purpose of this project, inefficient and low performing materials will be used to put emphasis on the worst case scenario and due to the fact that the building was built in the 1950s. The building will have low exterior material surface albedo (brick / stone cladding), low thermal mass (wood / steel framing, not CMUs), poor natural ventilation (not a lot of windows) , low thermal insulation ( low density fiberglass insulation, type of window) and poor shading (flat roof, no louvers, no blinds on windows). 4) Room Location: The room to be studied will be located on the top floor and is therefore the most critical due to the exposure of environment from the roof and windows and as with the simple notion that heat rises. 5) Space Use: For the project we will consider cooking as the main human activity and energy generated in the room since it creates the most heat. 1.2 Building Data 1) Room Dimensions: Width: 10 meters Depth: 8 meters Height: 2.2 meters Third floor of a detached triplex building with a flat roof.

2) Fenestration: South Wall: 1 x 2m x 1.5m double glazed single pane window (sliding). East & West walls: 1 x 1.5m x 1m double glazed single pane window (sliding). Factors to consider:
-‐ Window frame (conductivity) -‐ Thermal transmittance -‐ Solar heat gain coefficient -‐ Glass type – double glazed -‐ Glass: clear / tempered -‐ Insulating glass -‐ Filling between panes : air / argon -‐ Low E-‐coating -‐ Weather-‐stripping around frames
3) Outdoor conditions: -‐ Ongoing heat wave -‐ Maximum outdoor temperature: 34 degrees Celsius at 3 pm -‐ Minimum outdoor temperature: 23 degrees Celsius at 3 am -‐ Equivalent sky temperature = 5 degrees Celsius below ambient air temperature This will be used as the temperature for the roof design. 4) Solar Radiation: Use month of July 2012. See Table 1 in Appendix. 5) Air exchange rate: 0.5 when windows and doors are closed. Formula: a) !"# = ! !"#$%& !" !"#!$%&'%!("
! (!"#$%& !" !"#!$%&'%!(")
b) !!"# = !"# ! !"#$!" ! !!"# 6) Indoor activity: Cooking will occur for 2 hours per day, from 7-‐8 am and then 6-‐7 pm. 1 occupant will be home all day while the other will be at work from 8 am to 5p

2. Select Design 1) Walls (exterior to interior): -‐ Brick cladding -‐ 152 mm Fiberglass insulation (batt insulation) -‐ 12 mm Interior Gypsum Board For simplicity, we will neglect the air and vapor barriers and furring strips in the compositions. Also, we will neglect the wood / metal framing. The insulation goes in between the framing. 2) Floor (top to bottom): -‐ Finished floor : Hardwood -‐ 152 mm Fiberglass insulation -‐ 12 mm Interior gypsum board For simplicity, we will neglect the framing, furring strips, barriers and components needed for the finished floor. Also, we will neglect all acoustic components. To simplify the equations, we will consider the entire floor composition as one component and the conduction through the entire composition as one. 3) Roof (top to bottom): -‐ Standard built up roofing membrane -‐ 300 mm fiberglass insulation -‐ 12 mm interior gypsum board For simplicity, we will neglect the air and vapor barriers and furring strips in the compositions. Also, we will neglect the wood / metal framing. The insulation goes in between the framing. Also, we will assume the built up roof membrane to simply be felt

5. Create Matrix To solve for temperatures, we need to create a matrix. The matrix will be composed of a coefficient matrix, an unknown variable matrix and the solution matrix. The coefficient matrix will be a 22x22 matrix and will be composed of the constants of thermal conduction, areas, widths etc. that are multiplied with the unknowns (T1, T2, T3…). The unknown variable matrix will be a 1x22 matrix composed of the temperature variables at each point in each wall, the room temperatures , the roof temperatures and floor temperatures. Finally, the solution matrix will be composed of the constants multiplied by the outdoor temperatures that are known for each hour. See Table 5 in the Appendix 1.

4. Discussion North Wall Analyze: From the curve, we can see that the 4 points in the wall show more or less the same trend. The temperature distributions for the exterior face brick and interior of brick are almost identical to each other. There are temperature spikes mainly in Point 2 and Point 4. These spike occurs within the two hours of cooking. From the tables, we can see that the lowest temperature is 19 degrees Celsius at 3 am and the highest occurs at 38 at 5 pm in terms of the interior temperature of surface of walls. The temperatures at point 4 rise substantially during the hours of occupant activity. The North Wall experiences peak temperatures at the surfaces at 6 am and at 6 pm. Explain: The trend lines of a regular temperature distribution curve should follow each other more or less depending on factors such as seasons, activities, location etc. Also keep in note that there is no mechanical ventilation/ air conditioning system to regulate temperature fluctuations. During the summer, point 1 should experience the highest temperature due to solar radiation, convection and conduction. From the given information, the highest temperature should occur at 3 pm and the lowest at 3 pm. According to Table 1 in the Appendix, the peak solar radiation value should be at 12 pm in the North Wall. Justify: The lowest temperature in the North Wall does occur at 3 am however the temperature spike at 5 pm instead of 3 pm may be due to occupant activity (2 people) increasing. The 2 peaks at 6 am and 6 pm for solar radiation on the exterior face brick have an identical solar radiation value of 57. The reasoning of these peaks is unknown, however they probably are related to the sunset and sunrise times. South Wall Analyze: From the curve, we notice that the shape of the trends are very similar. We also notice that the point 4 curve temperature distributions are much lower and the slope is almost flat. At point 4 (inside surface), the lowest temperature occurs at 3 am and it is 21 degrees Celsius and the highest temperature occurs at 5 pm and it is 41 degrees Celsius. On the exterior façade at point 1, the lowest temperature occurs at 3 am and it is 49 degrees Celsius and the highest one occurs at 12 pm and is 108
18
degrees Celsius. As noticed earlier like the north wall, the curve rises in temperature during occupancy increase and peaks at cooking times in point 2. Explain The temperatures at point 3 and 4 should be very similar because the thickness of the gypsum board is small in comparison and because the temperatures are mainly affected by minor changes such as indoor convection. The south wall should experience the higher temperature distribution than the other walls due to the higher solar radiation values at each hour during the summer. Justify The main issue in the south wall comes from the minimum and maximum temperatures that hit the brick façade. The minimum temperature of 49 degrees and the max temperature of 108 seems highly unusual even though brick has a high thermal conductivity value. This may be due to the fact that considerations such as shadings, overhangs, surrounding buildings, trees etc. were not taken. Also it may be due to erroneous temperature values. The inside temperatures are viable because the south wall contains a large window which increases solar heat gains. East Wall Analyze: From a first glance, the trend of the curves on the east wall does not match at all and contain large gaps between. Another major error noticed is that point 2 is below point 4 and its values are extremely low. There is a large temperature peak on the exterior wall at 8 am with a temperature of 80 degrees Celsius. The interior temperature curve (T4) is fairly similar to the other walls and the temperatures are fairly average. Explain: The east wall experiences spikes in solar radiation especially between 6 am to 11 pm. A proper reasoning to this is may be due to orientations. According to the Canada Mortgage and Housing Corporation’s article on Solar Energy for Buildings: “Buildings with east and west facing orientations have greater potential for overheating in the non-‐heating season.” Justification: Since the other walls do not have the issue of point 2 being lower than point 4, the error must either come from solar radiation values or computation/input errors in Matlab.
19
West Wall Analyze: From the graph, the trend of the curves seems to follow fairly through. Point 3 and point 4 are almost identical. There is a large gap that varies from the exterior surfaces to the interior ones. Also at first glance, we can see that the west wall is almost symmetrical to the east wall. The west wall records the highest temperature on the exterior surface as opposed to the other walls. The highest recorded temperature is at 4 pm and it reads 140 degrees Celsius. Explain & Justify: The gap between the exterior surfaces and the interior surfaces may be due to solar radiation values. Only the north wall does not have this issue because of its lower solar radiation values during the summer time. The reason for the east and west curves being symmetric are due to the solar radiation values. The readings on the east wall are an inverse of the west wall. Also we can use the simple notion that the sun rises north or south of due east and sets north or south of due west. The reason why the west wall reaches the highest temperature is due to a combination of solar heat gains and outdoor temperature readings. The west and east wall have the highest solar radiation values (up to 679W/m^2). When this occurs at 4 pm, the temperature is already around 33 degrees which is almost 34 (the maximum outdoor temperature). Floor & Room Analyze: The floor and indoor temperature distributions are very similar to each other. The highest temperatures occur at 5 pm and are around 40 degrees Celsius. The lowest temperatures occur at 3 am and are around 19 degrees Celsius. The two peaks occur when both the occupants are at home and at high solar radiation values. The cooking hours have a low impact on these temperatures. Both graphs resemble the T4 curves of each wall, since it is the indoor surfaces. Explain & Justify: The reason for both graphs being similar to each other have to do with the fact these formulas indicates similar convection values. For example:
Hi ∗ A ∗ (T4− Ti) ≅ (Hi ∗ A ∗ Ti− Tf ) Where T4 is almost equal to Tfloor (for indoor surfaces) Also take note that the areas are identical
20
We also note that the 0.5 ACH value does not have a big impact on thermal heat gains in the summer. It might have a larger impact in the winter with heat losses. With peak temperatures reaching 34 at 3 pm, the curve should reach a peak at 3 pm instead of 5 pm. However, when taking into consideration solar heat gain from windows, increasing occupant activity, high outdoor temperature and cooking, it is reasonable. Roof The roof graph resembles the temperature distributions for the walls. The curves are more dependent on the solar radiation values rather than interior activities and materials. We can see that the curve for the roof surface is mainly active during the hours of sunlight.

5. Conclusion 5.1 Real Life Scenario After conducting this experiment, I have found that the occupants are not thermally comfortable especially from 2pm to 5 pm. The maximum indoor temperature reaches 38 degrees Celsius which is about 4 degrees higher than the maximum outdoor temperature. This is taking into consideration only cooking activities and not equipment such as refrigerators, televisions, computers etc. that might be on for a long time. A ventilation system is required to exhaust the indoor air out at least even if there isn’t an air conditioning system. 5.2 Room for Improvement Suggest techniques to improve the thermal comfort without the use of a mechanical ventilation system. Various techniques can be used to improve the thermal comfort without using a mechanical ventilation system or an air conditioning system. To minimize heat gains from the windows, we can begin by adding shading systems (roller shades and venetians) as opposed to curtains that can be heavier. This will cut the radiation coming from the sun especially through the south wall. Energy efficient windows can also be added. For the sake of the project, we used double glazed windows without an airspace. There are now double glazed windows available with low emissivity coating. This coating is a thin metal film applied to the glass that blocks enough solar radiation in the summer but also allows enough heat gains in the winter. Triple glazed windows with an airspace and insulated spacers are also available however they are more of an advantage in the winter time as they provide a higher R-‐value. Modifying building materials is also another way to improve thermal comfort. Materials with a lower thermal conductivity will provide lower heat gains through the walls. Facades that are made of stucco or of concrete finishing systems are a good choice because they have a higher thermal mass; meaning that they are cooled at night and they release this coolness into the building during the day. Also note that a proper air and vapor barrier are crucial to an overall proper envelope system. Another solution would be proper roof design. An overhang would help in shading the building to decrease solar radiation. Heat islands from roofs are being eliminated today with lighter surfaces, which as a result induce a higher surface reflectance. Green roofs are also a technique used to reduce heat islands.
