Location: Dartmouth, Nova Scotia

Client: The Hardman Group

Architect: Lydon Lynch Architects

Certifications: LEED Canada-CS Gold, ASHRAE 2015 Technology Award – Honorable Mention

Size: 87,000 sq. ft.

Project Budget: N/A

100 Venture Run is the first building built at the Wright and Burnside green building campus in Dartmouth, Nova Scotia.  This building is being used as a template for future buildings at the site so M&R analyzed building performance early in the design  process and performed a rigorous commissioning and measurement and verification process to verify that efficiency measures performed as expected. 

M&R Engineering was responsible for mechanical design including HVAC, Plumbing and Fire Protection as well as electrical design including Lighting, Power, Communications and Security and Sustainability Consulting (LEED Point Documentation, Commissioning and Energy Modeling).

Key Facts: 

• Efficient Building Envelope including R-20 wall and R-30 roof insulation

• Condensing Gas Boilers.

• Variable Speed drives are installed on circulation pumps and fans to save electricity and provide greater control.

• High efficiency (EER 10.5) rooftop VAV air handling units

• Domestic hot water is preheated by a flat plate solar hot water system

• Occupancy sensors are installed to reduce lighting power and HVAC when the room is unoccupied.

• Daylight sensors are used to control perimeter lighting; lights dim when there is sufficient daylight available.

• Cut-off fixtures are installed in the parking lot to reduce light pollution.

• Electric vehicle charging stations are located in the parking garage

• Low flow plumbing fixtures save water and energy used to heat domestic water: 4.8 L/flush toilets, 0.5 L/flush urinals, 1.9 L/min lavatories, and 7.6 L/min showers.

• Rainwater Cistern collects runoff from the roof and supplies toilets and urinals saving city water and reducing runoff into the storm system.

• Energy modeling indicated energy cost savings of 49% compared to the energy code (MNECB).

• Measurement and Verification was performed rectifying issues and indicating that energy savings were actually 50% compared to the energy code which is 60% savings compared to typical office buildings.
