3 INTRODUCTION Manitoba Hydro s Commercial Building Envelope Program is available to Manitoba Hydro General Service customers in commercial, institutional, and agricultural sectors. Residential and multi-unit residential dwellings without common areas are excluded. The Program offers financial incentives to upgrade measures with energy efficient measures in existing buildings. Incentives are available for: Insulation upgrades for renovation projects only; Window upgrades for renovation projects only. Power Smart Design Standards guidelines for commercial buildings Power Smart Design Standards guidelines are for new and renovated commercial buildings. Manitoba Hydro recommends incorporating these good practices to your building design. These guidelines cover most energyrelated systems in the building, including: insulation, windows/doors, air barrier, lighting, heating, ventilation, air conditioning, heated service water, electric power, and parking lots. Incentives are available for several products or systems that meet or exceed the guidelines. To obtain a copy of the Power Smart Design Standards guidelines for commercial buildings, contact your local Manitoba Hydro office, Power Smart for Business at , or powersmartforbusiness@hydro.mb.ca. The Power Smart New Buildings Program provides technical guidance and financial incentives for designing, constructing, and operating new, energy efficient buildings in Manitoba. All new commercial construction projects in Manitoba are eligible for incentives and building designation from the Power Smart New Buildings Program. For more information, contact your Energy Services Advisor (ESA), Power Smart sales representative, or Power Smart for Business programs.

4 HOW TO PARTICIPATE The following steps outline the process for applying for financial incentives through the Commercial Building Envelope Program. 1. Pre-approval is required to be eligible for incentives You must receive written approval from Manitoba Hydro before purchasing and installing any products, materials, or systems. Incentives may not be issued for projects that are started before written approval has been granted. 2. Determine energy efficiency requirements The customer determines which energy efficient product or system, including type of product and quantity, to install. 3. Complete application The customer completes the application(s) and submits them with the appropriate product specification sheets. Note: All information requested on the application(s) is important please ensure all information is filled in. Manitoba Hydro cannot process incomplete applications. Incomplete applications will result in delays in the approval process and may be returned. 4. Application review A Manitoba Hydro Energy Services Advisor (ESA), Power Smart sales, or program representative reviews the application to ensure products qualify for incentives and assists the customer through the application process. 5. Potential site verification A Manitoba Hydro representative may visit the building to verify existing or new products or systems. 6. Make any necessary changes Modifications or changes to the original application(s) (products or quantities) must be agreed upon by all parties. Failure to submit these changes may result in the application(s) being rejected. 7. Project authorization The Power Smart program representative provides the customer with written approval to proceed with the installation. The incentive is based on the installation of the qualifying product(s). 8. Documentation The customer completes the Completion Form and Questionnaire, after the products or system are installed and operational, and submits them to the ESA, Power Smart sales, or program representative. Itemized invoices are required. Customers can request these from their contractor, supplier, or consultant. Note: Payment of the incentive will be delayed if information is missing and the invoices do not meet Manitoba Hydro s requirements. For insulation projects, invoices must include: insulation type and product name; cut sheets for sloped roof insulation; quantity purchased (square feet, number of bags, thickness, etc.); unit prices and total (separate from labour and taxes). For window projects, invoices must include: window manufacturer; window type (awning, fixed, etc.); window model; dimensions and quantity of each type; unit prices and total (separate from labour and taxes). 4 Commercial Building Envelope Program PROGRAM GUIDE

5 For curtain wall projects, invoices must include: framing system (make and model of frame material, showing quantity in linear ft. and unit prices); glazing (type of glass, dimensions, quantity, and unit prices); spandrel (type, dimensions, quantity, and unit prices); glazing and spandrel cut sheets for curtain wall. All application correspondence can be sent to: Manitoba Hydro Commercial Marketing Programs Commercial Building Envelope Program 360 Portage Ave. Winnipeg, MB R3C 0G8 9. Cheque processing The ESA, Power Smart sales, or program representative receives all paperwork. He or she then forwards the paperwork to Manitoba Hydro s Power Smart for Business department for final approval and cheque processing. 10. Incentive The customer will receive an incentive from Manitoba Hydro once they have met all of the Program s eligibility criteria and participation requirements. Customers have the option of assigning their rebate to a third party (i.e. installer, distributor, etc.). To assign the incentive to someone other than the applicant, the cheque payment information on the customer information page of the application must be completed and signed by the applicant. Note: No incentive payment should exceed the customer s cost of the qualifying product(s). Incentives are limited to 100 per cent of the insulation/window product cost plus Goods and Service Tax (GST) or the total incentive, whichever is less. Commercial Building Envelope Program PROGRAM GUIDE 5

6 PROGRAM GUIDELINES AND POLICIES Product eligibility 1. All products must be new, of current manufacture, and meet applicable standards. 2. Products intended for exterior application must be rated for satisfactory operation from -40 C to 40 C. 3. Product components must not consist of or contain hazardous components (e.g. PCBs, CFCs, asbestos, etc.). 4. Manitoba Hydro reserves the right to request or obtain product samples for the purposes of technical evaluation and quality control. The manufacturer and/or designated agent will be advised of product details which are not to the satisfaction of Manitoba Hydro. During the course of the Program, randomly selected production samples will be evaluated for the same purposes. Any significant reduction in product quality and performance can result in the delisting of the product from the Program. Installation requirements 1.

Manitoba Hydro reserves the right to inspect the project with respect to elements relevant to the application. 5. All installations may be randomly inspected by an independent firm as approved by Manitoba Hydro. 6. Limited technical assistance may be available from Manitoba Hydro. Technical assistance may include savings and payback estimates. In some instances, Manitoba Hydro may supply a more detailed calculation of energy savings. 6 Commercial Building Envelope Program PROGRAM GUIDE

7 INSULATION UPGRADES Benefits Participating in Manitoba Hydro s Commercial Building Envelope Program can benefit your business in a variety of ways. Power Smart insulation upgrades will help: lower annual energy costs; reduce heating and cooling loads; create a comfortable, draft-free environment; reduce harmful effects on the environment; reduce condensation and moisture; enhance building durability; improve indoor air quality. Customer eligibility Manitoba Hydro customers that install roof and/or wall insulation to Power Smart standards in their facilities may be eligible for commercial insulation incentives. Applications must be pre-approved before renovations begin. Project eligibility Only renovation projects are eligible for commercial insulation incentives. The primary heat source in the commercial building must be natural gas or electricity in order to be eligible for commercial insulation incentives. Buildings using alternative heat sources will not qualify for the program. Renovations to doors only qualify for incentives if 50 per cent of the door is composed of glazing. Project restrictions Facilities with an indoor set temperature of 10 C (50 F) or less do not qualify for the full incentive. These facilities will have their incentives adjusted according to a pro-rated fraction of full energy savings for buildings with an indoor set temperature of 21 C (70 F). For partial installations, a minimum of 1,000 square feet of roof or wall insulation must be installed per incentive application. If the total qualifying area is less than these limits, the installation must cover the total qualifying area. Insulation upgrades to areas below grade (i.e. basements, foundations, and slabs) are not eligible for incentives. Product eligibility All insulation products must have thermal properties (R) listed by a recognized agency such as the Canadian Construction Materials Centre (CCMC). Manitoba Hydro may review an unlisted product to determine whether the product meets program requirements. Power Smart efficiency requirements The Program provides incentives to upgrade insulation levels (thermal resistance) to Power Smart requirements. The upgraded assembly must have an effective thermal resistance value that meets or exceeds the R-values outlined in Table 1. R-value is a standard unit for thermal resistance of building components. Effective R-value is the overall thermal resistance of a building assembly, including the air films on both faces and taking into account variations due to the other components, besides insulation. To calculate the effective thermal resistance of the assembly before and after it is upgraded, Manitoba Hydro includes the whole wall or whole roof assembly. Customers should include the description of the entire assembly. Even if there is currently no insulation, Manitoba Hydro still needs the description of all the other components in the particular assembly. The amount of the incentive is determined by what is there to start with (the existing assembly) and by the amount of insulation added to reach the requirements. Manitoba Hydro requires the assembly description to calculate your incentive. Commercial Building Envelope Program PROGRAM GUIDE 7

8 Tables 2 and 3 may help you determine the R-value of the existing assembly. Participation requirements Existing insulation, that is either damaged or to be replaced, will be counted towards the starting R-value of the roof or wall assembly. Insulated siding materials do not qualify as products in the Commercial Building Envelope Program. Manitoba Hydro will determine whether all of the Program requirements have been met. Product verification Manitoba Hydro reserves the right to verify that product installations meet the requirements of the Commercial Building Envelope Program through an independent third party pre- and/or post-installation review. If your project has been selected for verification of the building assembly, an engineer will ensure the assembly description is completed. Participating trade allies or contractors will notify Manitoba Hydro, at least three working days in advance, regarding situations where accessibility and visual inspection is only available at the time of installation. If the customer s preand/or post-installation inspection fails: Manitoba Hydro will notify the customer and/or the participating trade ally and provide the reason for failure upon completion of the review. The customer and/or participating trade ally will have 30 days after the date of the failure notice to remedy any problems identified by Manitoba Hydro and pass an additional Manitoba Hydro independent review. Otherwise, the installation will no longer qualify for a Commercial Building Envelope Program incentive. 8 Commercial Building Envelope Program PROGRAM GUIDE

13 WINDOW UPGRADES Benefits Participating in Manitoba Hydro s Commercial Building Envelope Program can benefit your business in a variety of ways. Power Smart window upgrades will help: lower annual energy costs; reduce heating and cooling loads; create a comfortable, draft-free environment; reduce harmful effects on the environment; reduce condensation and moisture. Customer eligibility Incentives for windows are available to all Manitoba Hydro commercial customers who plan to install Power Smart recommended energy efficient windows in their existing facilities. Outside Measurement (OSM) OSM of brick mould OSM of frame Rough opening Combination window measurements Project eligibility Renovation projects that involve whole window replacement are eligible for window incentives. An existing frame with new glass may qualify for an incentive only if the performance of the retrofit window has been determined by an accredited independent test lab and the overall U-value of the window, including the existing frame, is equal to less than For window installations, a minimum of 10 square metres of window area must be installed per incentive application. The commercial building being renovated must be heated by natural gas or electricity in order to be eligible for commercial insulation incentives. Buildings using alternative heat sources will not qualify for the program. Window U-value Window U-value is a measure of the rate at which heat is transferred through the window, glass, and frame. U-value is determined by testing or computer simulation of the heat loss of a window assembly. The lower the U-value, the lower your annual heating and cooling costs and the higher your incentive. Commercial Building Envelope Program PROGRAM GUIDE 13

14 Measuring windows Punched windows A punched window frame is glass within a defined opening that is surrounded by cladding. The outside measurement (OSM) of the window frame is required in the window measurement process, not including the brick mould. For combination windows, where two or more window assemblies are mulled together, an OSM of each individual window assembly is required. The U-value is attached to a given window assembly. The incentive is attached to the area and U-value of the individual window assemblies (whether independent or in combination). For example, a single horizontal slider is a complete window assembly, not a sliding sash and a fixed sash. A combination of a fixed window over a horizontal slider is considered two separate windows. Curtain wall systems A curtain wall is a non-load-bearing exterior wall typically composed of vertical and horizontal framing members, containing operable sash or ventilators, fixed lights or opaque panels, or any such combination. When providing measurements for curtain wall projects, measure the glazed and spandrel sections separately. Measurements can be the total area of glazing and spandrels, or centre-to-centre measurements of each panel. Window eligibility criteria Proof of energy performance (total U or U-factor) for energy efficient windows is an eligibility requirement for the program incentives and must accompany the application. Your contractor can assist with providing proof of energy performance. Punched windows Three ways to provide proof include: 1. ENERGY STAR Canada energystar.gc.ca Identify by model on the window incentive summary section of the application. 2. National Fenestration Rating Council (NFRC) nfrc.org Identify by CPD number on the window incentive summary section of the application. 3. Window test report If the window system(s) chosen are not listed on the ENERGY STAR or NFRC websites, please attach the relevant window test report(s) to the application. Your window supplier or manufacturer can provide you with a window test report that provides proof of whole window U or U-factor. Proof of energy performance is required for the standard test sizes of glazing (2 m x 2 m) and spandrel (2 m x 1 m). Proof can be provided by attaching a copy of the following to your application: Curtain wall systems For curtain wall incentive values less than $10,000 Manufacturer thermal charts; or Window test report, in accordance with CSA standard A For curtain wall incentive values equal to or greater than $10,000 Window test report, in accordance with CSA standard A Commercial Building Envelope Program PROGRAM GUIDE

15 Installation An energy efficient installation helps ensure the durability of the window and wall. The importance of installation cannot be overstated shoddy installation may reduce the benefit of an energy efficient window. For installation good practice guidelines, consult: A440.4 CSA standards; Energy Efficient Building Association (EEBA) builder s guides; Canada Mortgage and Housing Corporation (CMHC) publications; other building association publications. Top five high-performance window features 1. Glazing Triple glazing increases energy efficiency by adding extra air space and providing a surface for additional low emissivity (low-e) coatings. 2. Frame Vinyl, fibreglass, and wood frames provide comparable resistance to heat flow. Aluminum is more conductive, but may qualify with high-performance thermal breaks. 3. Coatings Low-e coatings reduce radiant heat loss and gain of the glazing and keep the interior glass surface temperature more constant, providing a more comfortable space. The coatings are available as soft coat and hard coat for different applications. 4. Spacers Often called warm edge, low conductivity insulating spacers reduce heat loss and the potential for perimeter condensation. 5. Gas fills Fill spaces between glazing with a lower conductivity gas, such as argon instead of air, to further reduce heat loss. Commercial Building Envelope Program PROGRAM GUIDE 15

16 APPENDIX A DEFINITIONS Air barrier The term is often used to refer to a film or membrane within the building envelope that provides control of air movement through the envelope. This control is actually provided by several components within the building envelope, not simply films or membranes. Attic A space enclosed between roof deck and ceiling with separation of rafters and ceiling joists (see cathedral ceiling). Base case system The system that would have been installed if the Commercial Building Envelope Program did not exist. For existing buildings the base case may be the existing system.

Glazing Refers to the glass or plastic panes in a window, door, or skylight. Gross wall area The total area of all walls, windows, and doors. Generally, the area is calculated by multiplying the wall height by the wall perimeter that is measured on the interior surface of the exterior wall. The wall height should be measured as the distance from the underside of the finished ceiling down to the top of the finished floor. Heat loss Heat is a flow of thermal energy driven by a temperature difference. Heat loss is heat that flows out of your building. Insulation density This is the number of fibres, per square inch, in an insulation product. Denser insulation brings higher resistance to heat, cold, and sound. Interior surface Material used to cover the interior framed areas or materials of walls and ceilings (e.g. drywall, plaster). Insulation All materials transfer heat at some rate, but any material that hinders or lowers the rate of heat transfer is called insulation. Integral In this context, it refers to insulation placed within the plane of the structural framing as in a typical wood framed wall. Loose-fill Both a style of packaging and installation of insulation. It is made of small fragments that can be poured or blown into place. Loose-fill insulation resembles raw oatmeal. Mineral wool In common usage, it refers to fibrous insulation processed from rock or mineral slag instead of silicate or glass. Net wall area The gross wall area less than the net window and door area including window and door frames. 18 Commercial Building Envelope Program PROGRAM GUIDE

Sheathing Plywood, gypsum, or wood fibre encasing walls, ceilings, floors, and roofs of framed buildings. It is the first layer of outer wall covering that is nailed to the studs or rafters. Shop drawings Drawings or product literature that is prepared by a manufacturer and/or supplier. Shop drawings are submitted to an owner s engineer or architect for review prior to supplying the equipment or products. Drawings may be the actual drawings prepared by the manufacturer to construct the windows or other product for a specific project. Simple payback period The period of time required to recover the extra (incremental) cost of implementing an energy efficient system, from the reduced utility bills. Interest costs and utility rate increases are not considered. Solar Heat Gain Coefficient (SHGC) The fraction of solar radiation admitted through a window or skylight, both directly transmitted and absorbed and subsequently released inward. It is expressed as a number between 0 and 1. The lower a window s Solar Heat Gain Coefficient, the less solar heat it transmits and the greater its shading ability. SHGC can be expressed in terms of the glass alone or can refer to the entire window assembly. Solar reflectance The degree of sunlight reflected by a surface. Spacer The component that maintains the space between the glazing surfaces of an insulating glass unit (IGU), excluding any sealants. Standard A440 window test size The standard window size used to determine overall U value, in accordance with CSA A440.2, of a window system. Casement windows have a standard test size of 600 mm x 1500 mm and fixed windows have a standard test size of 1200 mm x 1500 mm (± 100 in both cases). Thermal break An element of low thermal conductivity placed in an assembly to reduce the flow of thermal energy between conductive materials. Thermal bridge Created when materials that are poor thermal insulators come into contact, allowing heat to flow through the path of least thermal resistance. U-value A measure of the rate of heat flow through a building assembly. Most commonly used to express the rate at which heat is transferred through a window glass and frame. Unfaced insulation Insulation composed of a single material without a surface sheet of some other material. Vapour retarder Component intended to resist vapour flow through the building envelope. Also known as vapour barrier.
