Welcome to- Energy Design
Energy Design offers consultation, energy modelling and performance testing services
to the British Columbia new homes building community including: builders,
home designers, architects and engineers.
The energy modelling and testing services are certified by Natural Resources Canada
(NRCan) and form part of the official EnerGuide for New Homes (EGNH) rating system.
Energy Design is based in Victoria but can offer services across British Columbia.
This website provides information about the benefits of using these
services, how the process works, the services offered, detailed information
about the services, as well as an indication of the costs involved.
The various pages can be accessed via the links at top right of each page...

With the steady increase in fuel prices; a growing awareness of the threat of global warming; and the demand for more sustainable and energy efficient houses, the ability to design and build homes that perform significantly better is becoming increasingly important.
Incorporating Building Science consultation during the early (conceptual) stages of a building project can be a highly cost-effective strategy. It enables details to be introduced or changes to be made which can have long-term and significant benefits to the performance and cost of operation of the building over its entire life.
Energy modelling represents a valuable tool with which to ensure that the homes we build address these issues, it also offers builders a competitive and cost-effective advantage.
These services can be used to generate an EnerGuide™ rating for buildings which, when combined with programs such as Built Green™, can offer considerable credibility to a builder's reputation.
Furthermore, there is a strong possibility that the new edition of the British Columbia Building Code (BCBC) due out in 2012 will include considerably more stringent requirements for building energy efficiency, including possible mandatory Energuide ratings for new homes.
Consequently, the ability to predict and manipulate the performance of a project during the design stage will be of particular benefit to builders and home designers.
Using this service during the initial design phase of a project can be crucial, since it is much harder (and more expensive) to improve the performance of a building once it is built.
As a further incentive, a number of grants and rebates up to $5000 exist through BCHydro, FortisBC, and the CMHC, as well as SolarBC. A List of these and other grants can be found on the NRCan website.

How it works
Data taken from the plans for a new home is input into the HOT2000 software developed by NRCan in order to create an “energy profile” of the proposed building.
Using information about the design, size, location, orientation, foundation, walls, windows, doors and roof, as well as type(s) of insulation, heating, domestic hot water and ventilation, the software is able to calculate the energy performance of the building based on standard1 or specific use and occupancy patterns.
The software can be used to model the designs to give an idea of the energy-efficiency of the proposed building in order to show how close it will get to an intended target. Furthermore, if initial targets are not being met, the software can then be used to predict the effects of various changes in the design in order to achieve those targets.
1 For the purposes of energy modelling in HOT2000, Standard Occupancy is regarded as being 2 adults and 2 children in the home for 50% of the time, maintaining the home at an average temperature of 21 degrees C with no night time setback.
It also assumes the use of 225 litres of hot water per day, a heated basement or crawlspace (if there is one) and a standard level of energy usage for appliances, lights, etc.
This is a benchmark by which new buildings are modelled for comparison under the EnerGuide rating system and is not intended as an accurate representation of actual house occupancy or usage.
Energy Design is fully insured with Professional (Errors and Omissions) as well a Commercial General Liability Insurance.
