Design Statement The purpose of this Project is to retrofit & redesign the existing F Building of the Algonquin College, in the highest sustainability standards in order to improve the energy efficiency and meet a zero framework. Currently, the one story building is occupied by offices. The F building is located in Navaho Drive, Woodrofe Campus, Ottawa. Next to this building, on the North-East side is located the Residence and Conference Center building. On the North-West side of the F building, is located the parking spots for the office employees. It has also a direct public transportation access as it is just in the front of the building.

We are going to design Food Zone & Meeting place and the Residence unit . The residential unit will include: one master bedroom, one bedroom, one bathroom, a dining room, a living room and a storage. As per requirements this unit should have a private access from the offices and one parking spot.

BUILDING RETROFIT & REDESIGN

FOOD CENTRE WITH MEETING PLACE

STEPS AND GOALS TOWARDS NET-ZERO • The first step is to create the most efficient building envelope including slab, roof, and openings.

• The second step is to size proper mechanical equipment to service the interior space • The goal is to create a relationship between the building envelope and mechanical equipment that will allow for renewable energy to be an energy producer that can generate profitable energy.

LEED CREDITS

ALGONQUIN COLLEGE – FOOD CENTRE WITH MEETING AREA

Site development - The site is almost 100% buildings and hard surfaces. The new project is similar but have a green roof and some new landscaping to mitigate habitat, groundwater and micro-climate effects.

Re-use of existing structures and materials - primarily an adaptation of the existing bldg. with a green new roof, internal walls will be salvaged and reused where applicable.

Thermal comfort - Solar control to reduce overheating is will be achieved by selective glazing and window and shading device design.

Existing heavy steel structural framing will be fully retained.

LEED Strategies that can be incorporated to the design process

Maintaining existing openings with no additions windows Analysis shows, 91% of the floor area being underlit, this results in an increased demand in lighting Energy.

The Energy demand graph shows 90 of energy required per year.

UPGRADED BASE PROJECT OPTION A Daylighting visualization (to the right corner) shows that there is lack of daylight penetration into the inner areas of the building envelope, this zone aligns with the major functional space of the redesign. This zone will require increased artificial light usage The Energy demand graph shows 61,721kWh of energy required per year.

SIMULATION OPTION A HVAC – VAV. Return Air Package

In this option, the Annual Energy use intensity is 250kWh/sqm/yr and Energy cost is $29,928, but comes at a cost of a very poorly lit building envelope.

The building functions as a restaurant and requires to be lit which improves the comfort level of its users.

This option may be cost effective but doesn’t perform well for its proposed function.

SIMULATION OPTION B HVAC – VAV. Return Air Package

In this option, a combination of various HVAC system with the aim of achieving energy efficiency. The HVAC systems include Radiant floor, Ground source water heat pump & HRV. The combination of these systems creates a significantly reduced Annual Heating Energy of 22 kWh per sqm, Annual Gas use of 13,160 kWh, EUI of 180.7 kWh/sqm/yr & HVAC Energy per Unit area of 78.7kWh/swm/yr Along with a well illuminated envelope. This option has achieved energy efficiency.

This analysis shows us that the prescience of nearby structures doesn’t cast any significant shadow cover throughout the year across the surface area of the building and the site.

This gives a high potential of harvesting solar power on the building itself and the parking area.

SOLAR POWER - DESIGN

Total energy consumption per square foot of a commercial building in Canada is 22.5kWh/SQF. This analysis shows us that • 38 solar panels located on the roof the building covering 144SQM can produce 12.2kWp (12.2kWh) of power.

•

107 solar panels located over adjacent carport shading system covering 475SQM can produce 34.2kWp (34.2kWh) of power.
