Summary

The Province of B.C. has pledged to reduce greenhouse gas emissions by 33 per cent and to conserve energy equivalent to 50 per cent of B.C. Hydro's electricity demand growth by 2020. As climate change becomes an increasingly important issue, energy solutions are needed that upgrade an existing building's efficiency while retaining its heritage value.

As stipulated in the Standards and Guidelines for the Conservation of Historic Places in Canada, all upgrades made to heritage buildings must maintain the building's "character defining elements." Until the B.C. Building Code is upgraded to incorporate rehabilitation, building projects rely on a building inspector's knowledge of alternative compliance solutions for existing modern or heritage buildings.

For this B.C. Heritage Branch project, energy upgrade solutions that would allow buildings to retain their heritage values and character defining elements were researched. This work intends to provide guidance and knowledge about alternative compliance options that are acceptable under the new B.C. Building Code to homeowners, developers and building inspectors. In addition to a list of general solutions, six storm window solutions were designed and analyzed for their effective R-values. Though none of the solutions upgraded existing windows to new EnergySTAR required R-values, they did serve to double the energy efficiency of a case study window: an existing window at the Emily Carr House in Victoria, B.C.

The Emily Carr House was built in Victoria in 1864. Because of its designation as a National Historic Site, any improvements must preserve all character defining features of the building.

In addition, an energy audit of the Emily Carr House was conducted using the EnerGuide for Houses blower door test system. The National Resources Canada Hot-2000 software report generated by an auditor from City Green, in addition to one completed in-house, are analyzed in this report for their consistency and suitability for modeling heritage buildings.

Finally, a case study was undertaken in the dining room of the Emily Carr House using a heat shrink film kit to minimize air leakage around the windows and to increase the thermal barrier. This experiment was undertaken to compare with the theoretical values calculated using 1-Dimensional heat transfer analysis on the storm window designs.

The Project

A case study was completed to measure the current operating energy of the Emily Carr House using the Natural Resources Canada Hot-2000 software. An EnerGuide for Houses expert from Green City was then consulted to analyze the building, and the two models were compared. Note that the City Green analysis models certain energy upgrade solutions, while my analysis models the Emily Carr House only as it exists today. An explanation of software assumptions and presets is also provided.

Analysis of six alternative compliance window upgrade solutions are provided. The operable window is modeled from a window in the Emily Carr House boardroom. Although the results are generalized so as to be applicable to most heritage and existing windows, the benefit of modeling an Emily Carr House window is that the solutions can eventually be applied to the building. The energy efficiency of these solutions is also compared to a typical Energy Star window.

Finally, a case study of interior heat shrink film, the simplest storm window solution, is analyzed for its performance in the dining room of the Emily Carr House. The temperature difference, as the room currently exists, between inside the dining room and directly outside was recorded three times a day for a week. Heat shrink film, from a kit, was then applied to all dining room windows. The temperatures were again tested and then compared to previous results.

1 EnerGuide for Houses Analysis

1.1 EnerGuide for Houses The case study generated by the EnerGuide for Houses expert provides an EnerGuide rating relative to other houses considered to be in the same class as the Emily Carr House. The Emily Carr House received an EnerGuide rating of 31 on a 100-point scale. For reference, houses of similar age in Canada average a score of 44 on this scale. The report continues to state that the Emily Carr House could be rated as high as 80 if it implemented all of the EnerGuide recommendations. The EnerGuide for Houses analysis generates EnerGuide ratings based on the expert’s Hot2000 model of the house in its current form and with recommended upgrades. The EnerGuide rating also incorporates data collected during a blower door test. EnerGuide estimated annual energy consumption of the Emily Carr House to be 299 Gigajoules (GJ). Space heating of the current house was estimated to consume 250 GJ annually. By implementing non-heating upgrades to the house, the space heating energy consumption can be reduced to 108 GJ. By upgrading all thermal systems in the Emily Carr House, space heating energy consumption can be further reduced to 37 GJ. These values are summarized in Figure 1, taken from the EnerGuide report.

Figure 1 - EnerGuide for Houses Estimated Annual Heat Loss Comparison

The EnerGuide report also estimates annual heat loss, which it breaks down into subassemblies. These values are shown both for the Current Emily Carr House and after making the recommended improvements. The graph, taken from the EnerGuide report is given in Figure 2. Please see Appendices D and E for the complete Hot2000 reports on the Current and Upgraded Emily Carr House models generated by EnerGuide for Houses.

1.2 My Hot2000 Model In my case study of the Emily Carr House, the current house configuration is considered. No improvements are suggested or considered for this analysis. Since the EnerGuide rating is created using both Hot2000 model and blower door data, an EnerGuide rating cannot be generated in my analysis. The purpose of my analysis is to validate the two Hot2000 models, since they had different authors and used different modeling approaches. This Hot2000 analysis estimated annual energy consumption to be 310 GJ. Annual energy Space heating energy consumption of the Emily Carr House in this analysis is estimated at 291 GJ annually. Estimated annual heat loss is provided in the Hot2000 report by subassembly. Only the current Emily Carr House configuration is considered for this analysis. The graph summarizing annual heat loss by subassembly is given in Figure 3. Please see Appendix C for the complete Hot2000 report on my Emily Carr House model.

1.3 Comparison To validate these different models, the estimated heat loss values were compared. A numerical summary of each model is provided in Table 1. Total heat loss between my current Emily Carr House model and the EnerGuide for Houses current Emily Carr House model differs by 39.85 GJ, which is 10.68% of the total. Therefore, though different authors using different modeling methods generated the two models, both models are considered valid approximations.

1.4 Discussion of Hot2000 Models In all Hot2000 models, the window sizes are approximate. Windows on each side of the house were measured. However, measurements were not taken for each individual window. In the models, the correct number of windows has been incorporated for each side of the house. All of them are assigned the same approximate size. Only the upstairs quarters and downstairs kitchen were considered as living spaces in all of the models. The EnerGuide for Houses modeled upgrade windows as aluminum single glazed units. However, the alternative compliance solutions introduced in Section 2 provide a more substantive improvement than the aluminum windows modeled. The theoretical values for total annual energy consumption estimated by the Hot2000 models were approximately double the actual energy consumption at Emily Carr House for 2006. The EnerGuide for Houses model of the Current Emily Carr House predicted annual energy consumption of 299 GJ, or 83056 kWh. Actual energy usage in 2006 was 37494 kWh. The difference between actual energy usage and estimated energy usage is 45562kWh, or 54.9% of the estimated usage. The discrepancy between estimated and actual annual energy usage is due to the models considering year-round heating of all rooms within the house to comfortable temperature levels (around 20ºC). The first floor of the Emily Carr House is rarely heated, which reduces heating energy consumption.

2 Alternative Compliance Solutions

2.1 Alternative Compliance Methods of Operating Energy Reduction for Heritage Buildings

The following quotation summarizes many agencies’ views on retention of heritage building assemblies:

Consider replacing older, wooden exterior doors with metal, insulated units, which are more durable, easier to weather-strip, and maintain their appearance with lower maintenance needs. There is a trade-off between the aesthetics of the “heritage house” and thermal values.

-- Canadian Mortgage and Housing Corporation Renovating for Energy Savings

1 Background

BC Building Code, Division A, Appendix A Application to Existing Buildings (A-1.1.1.1.(1)) “It is not intended that the BCBC be used to enforce the retrospective application of new requirements to existing buildings or existing portions of relocated buildings, unless specifically required by local regulations or bylaws… Code application to existing or relocated buildings requires careful consideration of the level of safety needed for that building. This consideration involves an analytical process similar to that required to assess alternative design proposals for new construction.”

Windows (2.2.2, p.4): “The BC building code requires that windows be double glazed (or single with a storm sash.)” Conclusions (4, p.16): “Cost effective actions for electrically heated single family houses include:

• Advanced frame walls with increased insulation • Full height basement insulation • Ground source heat pumps • Compact fluorescent lights • Efficient appliances • Additional wall ceiling and basement insulation • Heat recovery ventilators with increased air tightness of the air barrier.”

National Resources Canada Consumer’s Guide to Buying Energy Efficient Windows and Doors: Windows: The Ratings Game (Section 6) “[M]ost fixed windows tend to have better Energy Rating numbers than operable ones. There are two reasons for this. First, the standard size for a fixed window is nearly twice as large as most of the operable windows and thus has more glass area relative to frame area. Frames are also thinner because they do not need separate moveable sashes. This translates into more solar gains and les frame losses… Second, fixed windows tend to have less air leakage compared to operable ones.” Doors (Section 9.1) “Doors have less impact than windows on the energy consumption of a home… because there are fewer of them.” The following summarizes the threat to wooden door industry and heritage door character: “A badly deteriorated door should be replaced with a new one with energy efficient insulation… New insulated doors are usually made of foam and wood covered with metal. Door frames are normally wood, clad with metal or vinyl.” National Resources Canada ENERGY STAR: “An ENERGY STAR window will have many of the following features: [those attainable by heritage windows are bolded.]”

• Double or triple glazing with a sealed insulated glass unit. [With storm windows.] • Low-emission glass. • Inert gas (argon, krypton) in sealed unit. • Low conductivity or “warm edge space bars.” [Can be added.] • Insulated frames, sashes and door cores. • Good airtightness. [By using weather-stripping and caulking.]

11

Qualifying Criteria “All ENERGY STAR qualified windows, doors, and skylights have been certified by an independent accredited agency for their quality and energy performance. Because of this, manufacturers often offer longer warranties for these products.” National Resources Canada Improving Window Energy Efficiency: Repairing Operable Windows (p.4) “If the window appears to be in good shape, it may be possible to improve airtightness by doing the following:

• Adjusting or replacing the sash locks or adding more locks to large windows. • Repairing or replacing hindges on casement windows. • Ensuring that caulking, weather-stripping and paint are not interfering with the

operation of the window. • Ensuring that weather-stripping is fully functional (ie. It should be flexible, be properly

located and make full contact between the sash and the frame.) Proper window maintenance includes annual cleaning of the hardware, tightening of hardware screws and lubricating moving parts… [A]lso replace any cracked glazing. If major repairs are required, consider seaking the services of a contractor.” Caulking (p.5): “Air leakage can be reduced by applying a constant bead of caulking around the window trim, at the mitred joints of the trim and between the trim and the frame ... Caulking on the outside of a window should be done only after interior sealing is complete. If the exterior is caulked first, it can trap warm, moist air in the wall, which can, in time, damage the wall.” Weatherstripping (p.5): “For older wood-frame windows, look for a good quality, self-adhesive plastic V-strip weatherstripping.” Exterior Storm Windows (p.7): “Exterior storm windows were once very common in Canadian houses and continue to serve a useful role in many applications… Exterior storm windows can be either seasonal or permanent… Permanent exterior storm windows are usually equipped with a built-in screen and sliding sash. When using exterior storm windows, the main interior window must be air sealed more tightly than the storm window to prevent moist household air from entering the space between the windows and being trapped, where it can condense and cause deterioration of the sash and frame.” Interior Storm Windows (p.7-9):

Page 15: Windows - British Columbia · upgrade an existing building's efficiency while retaining its heritage value. As stipulated in the Standards and Guidelines for the Conservation of Historic

12

“[Interior storm windows] reduce the risk of condensation because its surface is closer to warm room air. Any condensation that does occur is on the storm window, which prolongs the life of the main window. [They are also] lighter and more accessible than seasonal exterior storm windows and are therefore particularly useful on upper floors.” (First 2 options are inexpensive, do-it-yourself; third option is more expensive and requires a contractor.)

1. Heat-Shrink Film with Double-Sided Tape: “With this system, two-sided tape is used to attach the film to the window trim, after which the film is heated with a hair dryer to shrink it tightly across the window.”

Advantage: Good seal and visibility. Disadvantage: 2-sided tape can remove paint. Also, once system is installed window cannot be accessed without removing or puncturing film and film can only be used once. 2. Clear Plastic Film with Spline and Channel: “A rigid plastic channel is permanently

attached to the window frame using small nails, screws or double-sided tape. A clear plastic film is then stretched tightly across the window and snapped into place using the spline section.” Advantage: Plastic film is reusable for several years and airtight. Spline and channel system lasts for several years. Disadvantage: Film may reduce visibility.

3. Clear Rigid Acrylic Sheets with Snap-On or Magnetic Seals: “The snap-on system works like the spline and channel system except that it is more substantial because it holds a heavy acrylic sheet in place. The rigid glazing is easier to attach and remove than film, and it is easier to clean, is more durable and has a more finished appearance.” Advantage: More durable, reusable, easier to clean. Disadvantage: When acrylic sheets are not is use, they must be stored either flat or vertical in a cool place protected from exposure to sunlight.

4. **Double Window like at Lynn Valley School in North Vancouver**: Retains the original windows, but adds a second window casement system inside that can be opened to give access to the original window.

Technical Preservation Services, National Park Service, US Department of the Interior, by Baird Smith, Preservation Brief 3: Conserving Energy in Historic Buildings Inherent Energy Saving in Historic Buildings (p.1) “Many historic buildings have energy saving physical features and devices that contribute to good thermal performance. [They maximize] sources of heating, lighting and ventilation.” Air Infiltration (p.5)

Page 16: Windows - British Columbia · upgrade an existing building's efficiency while retaining its heritage value. As stipulated in the Standards and Guidelines for the Conservation of Historic

13

“Care should be taken not to reduce infiltration to the point where the building is completely sealed and moisture migration is prevented. Without some infiltration, condensation problems could occur throughout the building.” Attic Insulation (p.6) “Adding insulation in accessible attic spaces is very effective in saving energy… Problems occur if the attic space is not properly ventilated. This lack of ventilation will cause the insulation to become saturated and lose its thermal effectiveness.” Doors and Storm Doors (p.8) “Most historic wooden doors, if they are solid wood or paneled, have fairly good thermal properties and should not be replaced… [Insure] that caulking and weather-stripping is applied as necessary.” Wall Insulation (p.9) “The installation of wall insulation in historic frame buildings can result in serious technical problems… Introducing insulation in wall cavities without a vapour barrier and some ventilation can be disastrous. The insulation [will] become saturated, losing its thermal properties and … actually increasing the heat loss through the wall. Additionally, the moisture (in vapour form) may condense into water droplets and begin serious deterioration of adjacent building materials such as sill, window frames, framing and bracing…. There are two insulation types not recommended for wall insulation: urea formaldehyde foams and cellulose which use aluminum or ammonium sulphate instead of boric acid as a fire retardant. The cellulose reacts with moisture in the air and forms suphuric acid which corrodes many metals and causes building stones to slowly disintegrate.”

Heritage Canada, by Craig Sims and Andrew Powter Repair or Replace Windows in Historic Buildings: Arriving at a Sustainable Solution (p.2) “Residential wood windows can be in service for 100 years before requiring a major retrofit to remain in service for a second 100 years. Similarly, it is not unusual for modern windows to experience major, non-repairable failures to sealed units, vinyl welds, caulk joints and wood joints within 10 to 25 years. Today, most sealed units carry warranties of only 8 to 10 years.” “The most significant factor relating to heating costs and human comfort is air infiltration… The used of sealants on fixed joints in combination with weather-stripping on operable joints results in significant improvements and usually the CSA [Canadian Standards Association] can be met.” “CSA A440 also rates weather shedding performance. Because the construction and detailing of traditional windows … include[s] drip designs and angled sill slopes that ensure water sheds effectively.”

Page 17: Windows - British Columbia · upgrade an existing building's efficiency while retaining its heritage value. As stipulated in the Standards and Guidelines for the Conservation of Historic

14

(p.3) “[H]istoric windows are maintainable…. [Calling modern window assemblies] ’[m]aintenance-free’ is often industry double-speak for un-maintainable or disposable. Vinyl- or aluminum-clad widows do not require the cyclical painting that wood does, but they scratch and fade, factory applied sealants fail, and joints may separate. These forms of deterioration cannot be halted by maintenance. In the last few years the advice to homeowners from the window replacement sector has been that responsible homeowners should replace their windows about every 25 years…. [G]lass and aluminum are two of the most energy-dense building materials requiring the highest use of energy in their manufacture and recycling. Vinyl is a non-renewable petroleum product and in not bio-degradable.” National Resources Canada R-2000 Initiative “Breathe Easier” (p.2) “Ventilation – the elimination of stale humid air from the home and the introduction of outdoor air – is also very important.” (Heritage buildings, by their nature, provide considerable natural ventilation.)

2.4 Discussion of Storm Window Designs

1. The heat shrink film kit does not significantly improve the R-value of the existing window (R-0.81 versus R-0.79). However it does improve the air leakage around the windows; the difference in temperature between inside and outside rose from the base case of 5 degrees Celsius to 6.5 degrees Celsius.

2. There is little difference in R-values between the interior casement storm (solution 2) and

the exterior storms (solutions 3 - 6), (R-1.54, R1.55, R1.55, R-1.55, R-1.54, respectively). Consequently, decision making must instead focus upon historic integrity, aesthetics, ease of use, and maintenance and storage scenarios.

3. The benefit of using operable exterior storms is that they provide thermal protection in

the winter, and shading and ventilation in the summer. Furthermore, most of the wear occurs on the storms, not the original windows. As a result, storm windows can be left on year-round, thereby minimizing maintenance and storage costs.

4. Additional energy savings could be realized by using double-glazed low-emissivity or

argon-filled glass in the storm windows. Then, the window system would effectively be triple-glazed.

5. The window upgrade solutions do not consider the energy-saving effects of draught-

proofing by adding weatherstripping and caulking. Invisible products are available.

6. Although adding additional glazing units (solutions 2 – 6) theoretically succeeds in doubling the R-value of the existing window system (R-1.55 versus R-0.79), and halving the power required to maintain a room at 20 C when it is 0 C outside (9.54 W versus 18.45 W), it does not succeed in achieving EnergySTAR window ratings (R-2.9 – R-4.0).

7. Emily Carr House has only two operable single hung windows and two operable

casement windows. Therefore, operable exterior storms would only be required for four windows. Also, since the casement windows open inwards, exterior windows that open outwards would also be used upon them.

8. Further research is needed to determine solutions for Emily Carr House’s bathroom

original frosted glass windows which cover two full walls. The bathroom, and the windows, contribute to an uncontrollable temperature zone. The bathroom is very hot in the summer and freezes in the winter.

3 Heat Shrink Film Case Study The dining room on the ground floor of the Emily Carr House was selected for a case study on the Heat Shrink Film. Temperatures outside a South-facing external window and inside the room were recorded at 9:30 AM, 2:30 PM, and 7:30 PM every day between November 20 and 26, 2007. The heat shrink film was then applied to all the dining room windows. As before, the temperatures inside and outside the room were recorded at 9:30 AM, 2:30 PM, and 7:30 PM every day between December 3 and 10, 2007. Graphs of the temperature distributions and temperature differences are provided below in Figure 19 and Figure 20. In the scenario where no storm windows are used, the temperatures inside and outside directly correlate. The average temperature difference is 5 degrees Celsius. In the scenario with heat shrink film interior storm windows, the inside and outside temperatures are less correlated. The skewed data from December 3 is likely due to disruptions in temperature associated with applying the film. Overall, however, using the film produced an average temperature difference of 6.5 degrees Celsius. This value is higher than expected given the theoretical R-value calculated for this system (R-0.81) is only slightly higher than the base case existing window system (R-0.79). Therefore, the energy savings associated with reducing air leakage around the window are significant in an actual window system.

4 Conclusion As referenced in the BC Green Building Code (BCGBC) proposals, which are currently under review, embodied energy has a significant role in the analysis of energy consumption and emissions. Further, the Life Cycle Assessment in Heritage Buildings report demonstrated that operating cost comparisons alone do not fully consider the environmental impacts of demolition and new construction. There is, however, an increasing emphasis being placed upon the reduction of energy consumption and greenhouse gas emissions. It is critical that any alternative compliance methods, as they pertain to heritage buildings, have a scientific basis. Given that a heritage waiver is currently under public review, and that this waiver would excuse heritage buildings from the proposed Energy Efficiency Act, upgrade solutions are still required to improve the energy efficiency of heritage buildings while retaining their heritage value. In order to achieve the specific goal of determining the theoretical R-values (thermal resistance) for window upgrades that retain the original windows, heat transfer analysis case studies for six different storm window assemblies were completed. Since all six studies netted results that make them viable energy reduction solutions, albeit not to EnergySTAR rated new windows, it is proposed that they be inserted into the new BCGBC under the heading “Heritage Buildings – Alternative Compliance.” Further research of alternative energy upgrade solutions for building assemblies other than windows is required.

5 Recommendations This report represents a starting point for the in-depth research required to demonstrate that heritage buildings can achieve the standards required by the Building Code while retaining original materials and assemblies in the form of alternative compliance solutions. Further research is required that will continue to draw upon international examples as well as the experiences of the BC construction sector and tailored scientific research. At least one of the alternative compliance solutions outlined in this report should eventually be applied to the Emily Carr House. Additional weather-stripping and caulking around the windows would also be a good, and relatively inexpensive, method of reducing air leakage. Other solutions, as outlined in the City Green EnerGuide report, are recommended as long-term solutions; a cost benefit analysis would need to be completed to determine the financial and environmental costs of retaining versus replacing or augmenting existing systems. If upgrades are completed, and a second energy audit conducted within 18 months, EnerGuide grant money, up to a maximum of $5000, can be accessed. This grant money should act as incentive to complete certain energy upgrades (such as the addition of storm windows) soon. The intention with modeling the Emily Carr House using the EnerGuide for Houses system was to determine the suitability of Hot-2000 for projecting the energy efficiency of heritage buildings by comparing the theoretical values to actual costs. Given that this process is useful for determining and reducing areas of high-energy consumption, this process could be directed towards modeling older industrial buildings as retrofit projects. The benefit of using EnerGuide and Hot-2000 is that they are respected housing-industry systems. Quantifying the performance of heritage buildings in these systems increases the validity of the arguments for their preservation.

Analyzes the environmental implications of the renovation, rehabilitation and adaptive reuse of two case studies of older Canadian buildings that have been submitted to the Green Building Challenge. Angus Technopole Building, a locomotive manufacturing and repair facility in Montreal, and Red River College, part of a redevelopment in Winnipeg, were assessed using the not-for-profit Athena Institute’s Life Cycle Assessment software, the Environmental Impact Estimator. Particular attention is paid to the value of retaining original building materials and assemblies in these case studies. Proposes two methodologies for the assessment of rehabilitation projects. Method 1 measures the environmental costs of using new materials in a rehabilitation project against the benchmark of constructing a new building on the site, including the cost of demolishing the old building. The second approach analyzes the environmental effects avoided by rehabilitating a building using ‘environmental impact avoidance scenarios.’ Concludes that the process of Life Cycle Assessment is an important tool for analyzes proposed rehabilitation building scenarios.

Canadian Standard Association (CSA) Guidelines: Guidelines for measuring durability in buildings. Based upon the following three premises: 1. The achievement of durability requires that life expectancy be considered in the design procedures for buildings and their components; 2. The decisions taken during the life of a building, and even before the development of actual design documents, affect all subsequent decisions and resultant performance; and 3. Beginning with the initial concept for a building, the design process should take into account the environmental loads and deleterious agents to which the building components will be exposed. Athena Institute and Morrison Hershfield. “Service Life Considerations in Relation to Green Building Rating Systems: An Exploratory Study.” Carbon Footprint: A measure of the carbon dioxide emitted from the combustion of fossil fuels in the everyday operations of a business, an individual or household. It is usually calculated in terms of tonnes of carbon dioxide emissions per year. Carbon Points: A system whereby businesses are rated for their total carbon footprint. In order to lower their points, businesses can purchase carbon ‘credits’ from lower emitting businesses. Chemical Incompatibility (of materials): A factor that can reduce the service life of a building. Based on the principle that certain materials within an assembly will react with each other and weaken the overall assembly. Durability: The ability of a building or any of its components to perform its required functions in its service environment over a period of time without unforeseen cost for maintenance or repair. The following factors are taken into account when measuring durability: 1. Site Specificity: Durability is a function of a material in its environment, and environments change on a micro and macro level. An element on a building next to a river may have a dramatically different service life than the identical element on an identical building constructed on bedrock. Similarly, building elements resist different ranges of environmental stress in different regions. 2. Building Interior Environmental Loads: One of the factors that has a significant effect on durability is interior environmental conditions. The envelope of a building that is operated in a cold climate with high interior relative humidity is more likely to experience frost and condensation problems and resulting loss in service life. 3. Maintenance Information: Maintenance of materials and systems can dramatically affect service life, and in some cases can have the largest influence on service life (such as maintaining a paint coating on exterior wood). 4. Design Criteria: To achieve a reasonable service life, it is important to design and construct building elements in a manner suitable for the specific element used. The degree to which the ideal design is achieved for a specific element can have significant effects on the material’s service life. Athena Institute and Morrison Hershfield. “Service Life Considerations in Relation to Green Building Rating Systems: An Exploratory Study.” EF: Ecological Footprint. A measure of the load imposed by a population on nature (ie a building). Represents the land area necessary to sustain current levels of resource consumption and waste discharge by the population.

Environmental Performance Gap: The gap between the expected environmental performance of a building due to materials and technology and the actual performance of a building. Factor Method: A method of determining the service life of a building. Requires the following seven factors: A. Quality of components as supplied to the project; B. Design level of a component or assembly’s installation (e.g. how protected it is from elements which may degrade it); C. Work execution level or skill level of the installers; D. Indoor environment (e.g. whether the component will be utilized in a wet area such as a bathroom or kitchen, or in a relatively stable indoor environment such as a coat closet); E. Outdoor environment (e.g. northern climate, coastal climate, southern climate, etc.); F. In-use conditions (refers to specific use conditions of the building); and G. Maintenance level (what is the level of maintenance possible for the particular component for the span of its useful life?). The formula for calculating the service life, where ESL is the estimated (predicted) service life and RSL is the reference service life is: ESL = RSL x A x B x C x D x E x F x G.
