Energy Modelling
We can assist you in determining the amount of money you can save on energy costs by investing in energy-saving measures.
We can also contribute to the creation of Energy Models to make buildings continue to be more energy efficient by making use of all energy resources that are used in the building.
Energy Modelling will assist in determining which combination of energy saving measures results in the greatest savings and when returns on efficiency are no longer cost-effective.
National Energy Code of Buildings
Energy codes are widely acknowledged as one of the most cost-effective methods for improving buildings’ energy efficiency. The National Energy Code of Canada for Buildings (NECB) was developed in Canada as part of a commitment to reduce greenhouse gas emissions and enhance building energy efficiency. The technical requirements for energy-efficient design and construction of new and expanded buildings are outlined in the NECB, which applies to large buildings.
The NECB and a collection of National Model Codes are published together. Building design and construction requirements are addressed in these model codes, which ensure that new construction meets minimum health, safety, and performance standards.
The most cost-effective option is to build to code. During the initial design and construction phase, energy efficiency measures are most cost-effective. It costs a lot more to retrofit later. This is especially true when it comes to the building envelope.
The NECB focuses on five essential building components that are typically considered during design:
The building’s envelope, which includes the roof, windows, doors, and walls, is concerned with the rates of air infiltration and thermal transmission.
Lighting: Here, measures like using lighting controls, reducing lighting power densities, and making good use of daylight are all considered.
Systems for heating, ventilation, and air conditioning include heat recovery ventilation, insulating pipe and ductwork, and building automation and control systems that make it easier for equipment to work.
Service water heating considers all of the ways a building uses hot water. It also requires that water flow rates be limited and waste-water heat recovery be maximized, and it sets minimum performance standards for service water heating equipment.
Electrical power systems and motors: establishes standards for the selection of transformers and electrical motors, limits the size of conductors to minimize voltage drop, and establishes requirements for monitoring the energy use of electrical distribution systems.
