INTRODUCTION

Buildings in general are large consumers of energy and impact the environment through carbon dioxide emissions. The primary source of these emissions is from burning of fossil fuels directly or indirectly. Making new or existing buildings more energy efficient means fewer greenhouse gases will be produced and at the same time will reduce operating costs. Energy efficiency not only improves local air quality but also contributes to the City's goal of reducing CO2 emissions. Energy efficiency also makes economic sense. Energy-efficient buildings cost less to operate than other buildings. Furthermore, these buildings have better indoor air quality, reduce noise and dust infiltration, thus improving comfort, health and productivity. The design and development of new buildings must have a comprehensive and integrated process in order to achieve the maximum environmental and economic results.

PURPOSE

The intent of this guideline is to provide direction, information and/or minimum requirements in the design of new buildings or in the upgrading of existing buildings which will achieve optimum energy efficiency without reducing the building performance or occupant comfort. These guidelines do not apply to buildings intended for occasional or unheated use.

The minimum construction standard used should be the more stringent of either ASHRAE 90.1-2013 or the 2011 National Energy Code of Canada for Buildings (NECB). The NECB is a comprehensive energy efficiency building code that takes into account variations in regional climate conditions and energy cost. The NECB establishes minimum standards of construction for building components and features that affect a building's energy efficiency. Based on a study performed for NRCan, adherence to NECB resulted in slightly higher energy efficiencies than ASHRAE 90.1-2013 ranging between 9% and 17% (depending on archetype) in Toronto. To achieve a “green building” designation, LEED™ Canada offers certification to buildings with high energy efficiency and low environmental impact. LEED Canada for New Construction and Major Renovations is tailored specifically for Canadian climates, construction practices and regulations. The LEED Canada-NC Rating System recognizes leading edge buildings that incorporate design, construction and operational practices that combine healthy, high-quality and high-performance advantages with reduced environmental impacts. They provide a voluntary, consensus-based, market-responsive set of criteria that evaluate project performance from a whole-building, whole-life perspective, providing a common understanding for what

Page 5 of 15



constitutes a “green building” in the Canadian context. With four possible levels of certification (certified, silver, gold and platinum), LEED is flexible enough to accommodate a wide range of green building strategies that best fit the constraints and goals of particular projects. More information is available on Canada Green Building Council website - http://www.cagbc.org/ Toronto Green Standard New buildings in the City of Toronto are mandated to comply with Tier 1 of the Toronto

Green Standard. For more information on this standard refer to: http://www1.toronto.ca/wps/portal/contentonly?vgnextoid=f85552cc66061410VgnVCM10000071d60f89RCRD

ENERGY EFFICIENCY GUIDELINE CHECKLIST

It should be noted that this guideline is subject to the Toronto Green Standard, Ontario Building Code and any other Code having jurisdiction. The designer should use the following checklist to ensure that the building is designed to be energy efficient. All systems and services, especially the architectural, mechanical and electrical, should be closely co-ordinated with each other in order to produce the most efficient and cost effective result as possible.

ARCHITECTURAL

A.1 Building Orientation & Site

Select the most efficient orientation and shape of the building in order to minimize energy consumption.

Take into account the local surroundings and the environment in designing new buildings. When heating is the major concern, southern roof and window exposure should be maximized. When cooling is the major concern a building's southern roof and window exposure should be minimized. Walls facing prevailing winds should be well insulated and airtight.

Building and component orientation should maximize opportunities for ground source and solar energy (heating, PV) harvesting.

Select building elevations 5' above 100 year flood plain. Consider opportunities for increasing development density and building usage

with the goal to maximizing greenfield sites (example: reduce number of single floor buildings).

Remediation and redevelopment of contaminated sites are encouraged. Consider access to public transportation and bike lanes within close proximity to

building to minimize need for automobile usage. This enables minimal provision for parking while maximizing vegetation and permeable surfaces on site.

Page 7 of 15



A.2 Building Surroundings

Minimize area of impervious surfaces (especially asphalt parking lots - Asphalt

retains heat, raises the ambient temperature around buildings and thus increases building cooling loads. It prevents water penetration and thus contributes to flash flooding by overloading storm sewer systems).

Install porous paving plant vegetation - Reinforced Grass Paving Systems are strong enough to support heavy vehicle loads and yet are water permeable. A catch basin and underground drain system may not be required in these installations.

Eliminate curbs along driveways and streets to increase water infiltration. Install rooftop water catchments systems (cisterns) and use precipitation for

irrigation. Design vegetated swales and shallow infiltration basins to carry storm water,

instead of pipes (these may be designed to dry out between rainfalls, or may be small permanent wetlands).

Landscape design should take into account us of deciduous vegetation to allow for summer time shading and maximization of winter time solar gain.

A.3 Building Envelope Design the building with a minimum exterior surface area (wall and roof) to

minimize heat transmission for a given enclosed volume. All necessary air seals to be carefully detailed and/or specified for maximized air

and vapour tightness. Minimize all cold bridges in exterior wall assemblies, for example, at junction of

exterior wall, foundation wall and floor slabs on grade. Thermal insulation shall be as continuous as possible. Thermal co-efficient for the building enclosure to exceed Ontario Building Code

requirements where applicable, but, in any case, be not less than:

Building Element R-value Wall 30 Roof (with attic) 50 Roof (flat) 30 Basement (below grade) 20 Floor on slab 10

Page 8 of 15



A.4 Windows

The maximum window area shall not be greater than 35% of floor to floor wall area.

Consider triple-glazed, low emissivity argon or xenon filled to maximize energy efficiency. All glazing to be Energy Star rated. Shading co-efficient and "U" factor to be as low as practically possible.

Metal window frames and sash shall be thermally broken to reduce heat loss. Use of custom architecturally designed exterior shading devices is

recommended above the windows to maximize heat gain during the winter and reduce heat gain during the summer when sun is at its highest position.

A.5 Interior Design

Provide vestibules for all entrances to reduce infiltration into the building. Use revolving doors where frequent use is anticipated to reduce infiltration into

the building. Locate service area, washroom, stairs, corridors, etc., if practical, along the

perimeter of the building in order to utilize daylight and minimize the use of artificial light.

Group the spaces that have similar activities together in order to reduce the complexity of the mechanical system.

Reflections of room surfaces shall be as follows: Ceilings minimum 80 percent Walls minimum 50 percent Floors minimum 20 percent

MECHANICAL

M.1 Heating, Ventilating and Air-Conditioning (HVAC) System

HVAC system improvements offer the greatest potential for energy savings in most buildings. The first step for reducing HVAC operating costs in large buildings is to reduce HVAC loads. Properly designed, installed and maintained HVAC systems are efficient and provide comfort to occupants.

Page 9 of 15



Energy modelling and load calculations shall be completed for all new construction projects to optimize energy performance of the HVAC systems. The results from the energy modelling shall be at least 30% better than the base building systems specified in the National Energy Code. All HVAC systems shall be controlled and operated by building automation systems (BAS). For retrofit projects; tie in new HVAC equipment with the existing BAS system installed at the site.

M.1.1 Heating and Cooling

Provide adequate zones for control. Temperature adjustments are to be made by BAS systems only. No local

adjustments shall be allowed. Use automated control to provide both occupied and unoccupied mode. Use a Direct Digital Control (DDC) system for all energy using equipment. The

City of Toronto's Standard BAS Specification to be used for all BAS work and can be found at http://insideto.toronto.ca/fred/ewm/bas.htm)

Use equipment with highest practical Seasonal Energy Efficiency Ratio (SEER) or highest coefficient of performance (COP) under both full and part load conditions.

For large cooling and refrigeration systems (greater than 100 tons) variable frequency drives (VFDs) shall be used for the compressors.

Choose the systems based on building's calculated cooling load. Unitary air-conditioning equipment is often oversized, which can significantly reduce efficiency and humidity control. At low loads, the efficiency can be less than half of the full load efficiency.

Use heat/energy recovery systems from exhaust air. Use air economizer and/or water side economizer systems to reduce the use of

mechanical cooling. Use condensing boilers. Use primary/secondary system design with differential pressure control and

VFDs for the secondary loop pumps. Use air flow stations to accurately measure and regulate the fresh air

requirements. Consider the use of renewable energy sources (eg. ground source heat pumps,

solar pre-heating of ventilation air, solar thermal or, photovoltaics) where feasible.

M.1.2 Ventilation

Page 10 of 15



Outside supply air for typical office space shall be based on OBC 2012 and ASHRAE 62.1 – 2010.

Use Demand Controlled Ventilation (DCV). DCV can be achieved by determining air quality by the amount of CO2. Acceptable CO2 level in commercial and institutional buildings is 1,000 parts per million (ppm), with outdoor air concentrations at about 400 ppm. A typical control setpoint would be 800 to 900 ppm (ASHRAE). DCV can save up to 50 percent of fan energy and 10 percent of heating energy for a system during occupied hours, compared to non-optimized control systems.

The minimum air circulation rate for occupied areas shall be 3.5 L/s for each square metre of floor area.

For large air-handling units, variable air volume systems (VAV) with static pressure control shall be used in conjunction with VFDs.

Minimize the fan operation during the unoccupied periods. Use variable speed drives where feasible (see E2 Motor section).

Use dampers with low leakage. Humidifiers and dehumidifiers must be provided with an automatic humidity

control device and must be connected to the Building Automation System. If the purpose of the humidity control is comfort, the controller must be able to prevent the use of energy to increase relative humidity above 30% or to decrease it below 60%.

Consider using gas-fired humidifiers (lower cost to operate). For enclosed or underground parking garage, use CO sensors to control the

ventilation system.

M.2 Domestic Hot Water (DHW) System

Use condensing natural gas hot water heaters. (Take advantage of Enbridge Gas Distribution’s Energy Efficiency Incentives outlined in Appendix A)

Incorporate a controller to turn off the circulation pump during unoccupied hours, or use low speed in a 2-speed motor.

Set the water temperature no higher than 48° C in the DHW system, and use local booster where higher temperature is required.

Insulate all DHW piping and tanks. Use a separate boiler for DHW heating if DHW is the only summer load. Use low-flow plumbing fixtures (see below).

M.3 Domestic Water System

All faucet aerators to have a flow rate not exceeding 3.8 L/min

Page 11 of 15



Shower heads to have a flow rate not exceeding 6.0 L/min. Toilets to have water consumption not exceeding 6.0 L/flush. Urinals to have water consumption not exceeding 3.8 L/flush (consider

waterless urinals). All faucets, showers, toilets and urinals to have automatic shutoff based on

infrared occupancy technology. Minimize water for irrigation. Reclaim rain water were practical. Use water softening system to minimize cooling tower blow-down. Use VFDs on the building's booster pump system and tie into the building's

BAS.

ELECTRICAL

E.1 Lighting

Use natural light as much as possible. Avoid overly bright spaces by providing adequate levels of illumination as

published in the Illuminating Engineering Society's Lighting Handbook. Locate workstations requiring the highest level of illumination nearest the

windows. Use fixtures, lamps and ballasts providing the highest illumination efficiency and

cost effectiveness. For example use LED lamps or high efficiency fluorescent lamps and ballasts.

Incandescent lamps should not be used. Use dimming systems to reduce energy consumption and/or when daylight is

sufficient. Use no power or low wattage/long life exit fixtures (eg. LED, photoluminescent). Use photocell control to turn off lights when natural light is sufficient for the task

(daylighting). Consider using indirect lighting systems where indoor light is directed towards

the ceiling level and reflected back down into the room. This provides a more uniform light with less glare. By providing more uniform lighting to a space, indirect lighting allows for a reduction in light levels. This translates into significant electricity savings and a reduction in cooling load. For example, light levels in offices can be reduced from 500 to 300 lux.

Provide alternate switching or dimming controls in multi-purpose spaces with varying illumination requirements.

Page 12 of 15



Provide local switches for all rooms. Use timers and/or photocell for all exterior lighting. The timer should be capable

of providing 7 days adjustments and seasonal daylight schedule variations. In rooms used periodically (eg. washrooms, meeting rooms and offices)

consider the use of occupancy sensors. For building lighting system use a fully automated lighting control system and tie

into the BAS.

E.2 Motors

Use high or premium efficiency motors for all applications (greater than 1 HP) which operate more than 750 hours per year. Energy represents more than 97 percent of total motor operating costs over the motor's lifetime. Higher initial capital cost for a more energy efficient motor is often paid back in energy savings within 4-7 years. Energy-efficient motors, in general, are of a higher quality, are more reliable, last longer, have longer warranties, run more quietly and cooler and produce less waste heat than their less-efficient counterparts. Use VFDs on large HVAC motors (greater than 5 hp). Inverter duty type motors shall be used.

E.3 Other Electrical

Connect energy meters to the building automation system. Install sub-meters on large energy using systems in the building. Specify transformers with low power loss. Ensure high power factor equipment. Minimize or eliminate the need for snow melting. Any electric baseboard heating to be controlled by local sensor and is to be enabled

by BAS. Other Considerations:

Energy modelling should be completed for all new buildings. Full point to point commissioning and documentation is to be part of the project

close out. Ensure contractor provides as built drawings, equipment and maintenance

documentations. Involve operation staff in every phase of the project to ensure operation and

maintenance issues are resolved prior to finalizing the project. The above list does not cover all the energy efficiency possibilities available in the design and renovation of buildings. It is also recognized that as energy prices and as new technologies become available addition energy saving measures should be considered.
