These drawings represent the minimum level of what a client should expect for engineering services related to indoor air quality and thermal comfort for a residential project adhering to requirements such as Alberta Standata 06-BCI-012 for Hydronic heating Systems, ASHRAE Standard 55 and ASHRAE 62.2 or CSA F326

Project Documentation
It is important to fully understand that a complete set of documents for a hybrid HVAC system requires not only an exhaustive review of the architectural specifications but also a critical eye of materials and methods of construction to optimise the building and HVAC system. This includes a full analysis of the window and door specifications including a review of U-values, solar heat gain coefficients, visible light transmittances, and spectral coatings. It also requires an assessment of the effects of air tightness, framing factors and window to wall ratios on enclosure R-values and thermal bridging and it's affect on thermal comfort and indoor air quality. Additionally it requires an assessment of interior finishes for heat transfer, off gassing and particulate generation. All this and more is required even before sitting down to evaluate the heating, cooling and ventilations loads and ultimately the production of drawings for bidding and construction (see below). You will only obtain this level of service from an independent design professional who understands the integrated design process.

Following is approximately 85 hours of professional services for a 4500 sf Home and Carriage House. Services included all of the above with two exhaust and make up air systems for the kitchen ranges, heating, cooling and ventilation for the occupants, domestic water heating in both buildings and design of two mechanical rooms.
