Energy Modelling

Building Energy Modelling uses a computer generated (virtual) reference building which has equivalent architectural, thermal, and electrical characteristics of a design/target building to predict energy performance of the design/target building.

Using Energy Modelling

Limitations of Energy Modelling

ASHRAE Standard 90.1 User’s Manual cautions that the modelling guidelines presented in the standard are intended to provide a baseline for comparison of the estimated annual energy cost of the proposed building and the baseline building for the purposes of a rating. They are not intended to provide an accurate prediction of actual energy consumption or costs for the building as it is actually built.

Even the best energy modeling tools make approximations and assumptions for how systems actually behave, e.g. variations in occupancy, control, maintenance, weather, energy rates and the precision of the simulation program.It is because we cannot predict the future.

Our engineering and technical staff have extensive experience across numerous energy technologies, project types and facilitates. We have extensive technical depth, knowledge, and practical experience with new energy systems design and existing system evaluations and retrofits. Our expertise includes project evaluations, studies, reviews, design, implementation and verification of all forms of building energy systems, some of which can be found listed below:

Energy Systems Analysis

Energy Systems Analysis develops a methodology to measure the technical impact of energy and materials usage, using software models to create quantitative comparisons of energy technologies. This analysis enables understanding of how to take advantage of opportunities within the building to reduce emissions and increase the efficiency of energy systems.

Energy Audit

An energy audit ascertains the major concerns about how energy is being used (when, where, why, how is it being used?) and gives data that can be used to greatly improve efficiency, reduce energy costs and GHG emissions, and confirm the overall effectiveness of the energy-efficient measures that have been implemented.

Energy Efficient Buildings

Energy efficient buildings are designed to produce major reduction of energy requirements for heating and cooling, independently of the equipment chosen to heat or cool the building. For either constructing new buildings or upgrading existing buildings, the implemented design will incorporate steps to minimize energy loss (for example: using the building envelope to decrease loss of heat) and allow the building to make the most out of the energy that is supplied to it.

Passive House

The Passive House high-performance building standard is an internationally recognized, science-based energy standard in construction. Applicable to almost any building type or design, this standard is capable of controlling indoor air quality and providing consistent temperature with simple to use and durable systems.  Passive House design can reduce heating and cooling energy up to 90% compared to conventional buildings, causing significant reductions in operating costs that quickly outweigh any associated construction costs, and reducing carbon emissions to minimize the building’s carbon footprint.
