Mathison Hall - Haskayne School of Business, Calgary, AB, Canada

Mathison Hall -  Haskayne School of Business

The Haskayne School of Business with the existing Scurfield Hall will be extended with the construction of the Mathison Hall and include a new common atrium and foyer.
After analyzing the local climate and its opportunities and challenges, Transsolar designed the climate and energy strategy and analyzed the main concept elements in terms of their performance in order to develop a comprehensive overall concept for the different parts of the project.
The new building is attached to the existing hall. This will improve the ratio of surface to volume for both buildings. In addition to this, energy will be generated by photovoltaic modules on the roofs of both buildings.
Four types of façades were designed, adapted to the requirements and function of the adjacent rooms.
The double façade, which is exposed to the highest solar radiation, is designed to provide natural ventilation of the building's atrium. It enables passive solar gains during the winter months.
A box window concept was developed. Clear triple glazing on the inside and bevelled single glass on the outside integrate the shading system in the ventilated cavity, protected from the weather. Instead, a selectively coated triple glazing with reduced surface area and internal sun protection was realized.
The single-glassed façade of the atrium areas allows natural ventilation and reinforces this through its chimney effect during the morning hours.
The event room is built with double height. Due to the high solar radiation in the shoulder seasons and in summer, its façade is composed of glazed and opaque elements, optimized for visual and thermal comfort.
A particular challenge of the project is the planned registration with the current Canadian Green Building Council Zero Carbon Construction Pilot Program. It has the goal of achieving a net zero emission of CO2 in building operation.
This challenges the entire planning team to ensure that the building's energy requirements are kept so low that, with appropriate integration of efficient renewable energy producers, the energy required is balanced out with locally generated energy, converted to equivalent CO2 emissions.
The balance also depends on the ecological footprint of the existing energy supply system of the campus district, therefore Transsolar has carried out an analysis so that the relevant values of greenhouse gas emissions now reflect the current status.
