Station Pointe Condominium & Retail

3d-energy-station-pointe-condo-retail-featured

Station Pointe is a redevelopment of the historic Fort Road Old Town area in Edmonton, Alberta. Phase I of the project is a mixed-use development where people can live, work, shop, and attend community events and programs. The design will include rainwater harvesting, on-site biological water treatment, natural ventilation, passive solar, solar thermal and solar PV, heat recovery, and efficient control strategies. A district energy system will have the potential of energy sharing with future phases of the project and with neighboring industries. Station Pointe is targeting net zero energy use and is located next to a Light Rail Rapid Transit (LRT) Station and bus terminal making it the new exemplary model for sustainable living.

Northern Development and Investment Group Audit and Solar Project

3d-energy-northern-dev-invest-group-audit-solar-project-featured

This facility is a single-story office building that was constructed circa 1976. The building has a total floor area of approximately 58,700 ft².

With three major tenants. After completing an analysis of the building’s exterior and interior envelope, heating/mechanical equipment, lighting equipment, windows, doors, and other systems and interviewing the maintenance staff, 3D Energy brought forward recommendations that included: Near Condensing Boiler Upgrade; Outdoor Condensing Unit Upgrade; Variable Speed on AHU Fans; Pneumatic to Electronic Control Conversion; Interior & Exterior Lighting Upgrade; Low Flow Water Fixtures; Insulation Upgrade; Programmable Thermostats; and Heat Recovery. Additionally, 3D Energy made a number of recommendations for the end of lifecycle equipment replacement.

Allan & Jean Millar Recreation Centre

3d-energy-allan-jean-millar-centre-featured

3D Energy was engaged to complete a Detailed Energy Audit (ASHRAE Level 2) on this facility.

As the prime contractor, 3D Energy performed the vast majority of the work including the site visit, energy modeling, analysis, and reporting, with some mechanical & electrical support from our sister company Vital Engineering as needed.

This recreation multiplex located in Whitecourt, AB includes offices, commercial space, lounge, children’s play area, conference facilities, running track, fitness centre, fieldhouse, and an indoor water park. We identified a total of nine ECMs including air handling unit variable frequency drives, pool variable frequency drives, low flow faucets, lighting occupancy sensors, lighting upgrades to LED, and a combined heat & power (cogeneration) unit installation.

The recommended measures would have a simple payback of five years and take the equivalent of 340 cars off the road each year.

Bio-Safety Cabinet Installation

vital-engineering-bio-safety-cabinet-install-featured

Biological safety cabinets were added to two buildings: The Cross Cancer Institute and the Walter C. MacKenzie building.

Supply air was adjusted within the spaces for increased airflow; new exhaust fans were selected for the rejected air stream, including new Strobic fans for the Cross Cancer Institute. Sensitive balancing, directional airflow, and general VAV upgrades followed as a result. Biological safety cabinet system design has many of the same rigors as fume hood design, except that the BSCs protect the product in addition to the users of the device.

St. Joseph 4-12 School (Whitecourt)

vital-engineering-st-joseph-school-whitecourt-featured

This new school, budgeted at $21,894,000.00, was delivered as a design-build for grades 4 through 12 in Whitecourt, Alberta.

The project was completed in 2017. The school uses displacement ventilation for cooling and fresh air; building heat is provided by hot water heating to radiant panels from mid-efficient gas-fired boilers. Both enthalpy wheels and core type heat recovery ventilators were employed on the air systems. Occupancy controls and demand controlled ventilation were implemented to save operating costs.

P143 Metalworking Shop Plasma Cutter

vital-engineering-p143-metalworking-shop-featured

NAIT’s metalworking shop purchased a plasma cutter- VEC provided the engineering for the necessary building infrastructure.

This included a pulse-controlled dust collector, welded industrial exhaust duct, and piping/controls for various exotic compressed gases (specified to medical gas standards). The addition of a spark arrestor permitted the plasma machine to be used on several different types of metal.

NAIT V102/V111 Carpentry Shop Dust Collection System

vital-engineering-nait-carpentry-shop-dust-collection-featured

The carpentry shop at NAIT went through a major overhaul, with existing and new equipment re-configured within the space.

Existing dust collectors were retained while most of the exhaust ducts were demolished; new ducts and blast gates run to the new equipment locations. Compressed air connections were also relocated per new equipment configurations. Vital ensured all relevant NFPA, SMACNA, and Industrial Ventilation standards were upheld and helped the users develop control strategies to mitigate the diversity of loads within the system.
