5. Permits and Regulations
• Building permits and regulations are enforced by the City
of Vancouver to ensure safety and livability for you, your
neighbours, and future property owners and residents.

6. Permit Application Process
• Step 1 - Document the building before
work
begins
• Step 2 - Document the proposed changes
• Step 3 - Arrange for a Letter of Assurance
• Step 4 - Arrange for a Letter of Credit
• Step 5 - Apply for a development permit
• Step 6 - Arrange for a final inspection

7. Constructions Damage Deposit
• The heritage buildings in Vancouver either
renovations or new constructions will
require a refundable damage deposit
before the building permit issued.

8. Inspections
• Inspections is to ensure that renovation or
construction work complies with the
relevant bylaws, and meets the City's
goals around life safety, accessibility,
green buildings.

9. Fees
Deposit Fees
• The deposit will be at least $1,000. For
single family homes, the fee is typically
$2,000. For other projects, the deposit may
be significantly larger.
Inspection Fee
• The inspection fee will vary, based on the
size of the project. For 2012, the fee ranges
from $166.45 to $3,221.71.

10. Utilities locations and Construction
• Modern City has to complex network of water,
telephone, electrical , voice communication
carrier pipes below ground.
• Due to the utility installations need to be safe,
the staff review proposed construction to ensure
they meet all the requirements, policies,
procedures and protocols.

11. Benefits of energy efficiency
heritage buildings in Vancouver
1) Installation of :
• Fireplace
• Chimney

12. 2) Embodied energy
• The buildings retain their embodied
energy.
• The energy used in lifecycle of a
building which are
• Initial Energy
• Recurring Energy
• Operating Energy
• Energy to demolish and dispose of the
building

13. 3) Low Energy-Intensive Building
• Example of materials for construct building are woods and bricks
• Reduce greenhouse gas emission

14. Benefits of energy efficiency of overall
heritage building
• Thermal mass
• Natural Ventilation System
• Construction of timber floor
• Installation of insulation
• Produce lesser unwanted substances

15. Disadvantages
• Thermal Bridging

16. Case Study: City Of Vancouver
• Heritage buildings mostly 20th century.
• 2150 of registered heritage buildings.
• The large amount of heritage buildings in a city
may cause huge energy consumption.
• How to solve it? “Vancouver’s 2020 Greenest
City Action Plan”.

25. Possible Problems and Precautions
 Construction
 Check the materials status
 Performance done by workers under control
Decay , quality , outlook and design affected
 Breathing performance
 Exchange air with outdoor environment
 Modern materials will affects the breathing performance
as well as trap moisture
Increasing of decay and damp problems

26.  Financial cost and payback
 Hire professions to control the quality of works
 Cost more due to heritage buildings
Much more expensive than a normal building
 Repaint and repairing
 Common paint-staking
 Extra cost of paint to take care the properties of
building
Affect the bonding strength of paint
Possible Problems and Precautions (cont’d)

27. Recommendation for
future improvement

28. Things to do before renovating the
building:
1. Identify the parts of the building we need
to upgrade
2. Request an energy improvement plan
that establishes priorities and
alternatives, including life cycle from
energy auditor.

29. Method to improve energy efficient
1. Install components that provide natural
ventilation and light
• Example: windows, interior courtyards, skylights and roof ventilators
• Reduce the use of mechanical ventilation
• Minimize the cost of electricity
• Maintain the thermal comfort, example: heat can be dispersed from
the building through these openings.

30. Method to improve energy efficient
2. Build thick masonry wall
• Have substantial mass and high thermal inertia
• Enable heat to be reduced in the building during hot weather and
traps heat during cold weather.
• Suitable to all climate weather
• In summer, heat absorbed at the outer surface of the wall takes a
period of time to transfer to the interior part of wall.
• In winter, heat is trapped within the building by dampening the
overall peaks of heat gain and loss.

31. Method to improve energy efficient
3. Install wide overhang roof (hot climate) or
sloping roof (cold climate)
• Wide overhang roof creates porches that can minimize the heat
absorbed from the sun
• Apply light coloured roofs to greatly reduce heat absorbed
• Sloping roof has no overhang prevails which allows the shedding of
snow
• Increase the beneficial solar heat gain through windows

32. Method to improve energy efficient
4. Floor plans
• In cold climates, the design of the building should be low ceiling
• Allows the heat to be shared more frequently inside the building
• Small windows with interior shutters should be installed to reduce
drafts and heat loss from the building
• In hot climate, wide central halls with high ceilings, breezeways and
large porches should be designed
• To maximize the air circulation.

33. Method to improve energy efficient
5. Repairing and weather-stripping windows
and doors
• Use draft-proof interlocking zinc, bronze or stainless steel weather-
stripping
• Add or tighten exterior or interior storm windows and doors with
gasket
• Allow for weep holes along the bottom rail to drain or vent
condensed water vapour
• Determine and seal locations of air infiltration

34. Method to improve energy efficient
6. Reduce energy demands for heating and
cooling
This can be done by 2 steps:
1. Upgrade to mechanical systems and major appliances (make sure
that we do not make alterations or adding new materials)
2. Corrective work or treatments, such as weatherization, that require
other alterations to the building may be considered.
