HIGH PERFORMANCE BUILDINGS

High performance buildings are much more than just the traditional definition of being green.  High performance means the integration of electrical & mechanical systems, building envelopes, and exterior and interior environments to create spaces that are efficient and optimized for comfort and safety.  Examples of high-performance building standards and rating systems include LEED, Passive House, Net Zero, and the BC Energy Step Code.

THE BUILDING REVOLUTION

Smart design that takes into consideration high performance building attributes such as durability, life cycle analysis and the comfort and safety of occupants, while simultaneously optimizing building systems and decreasing energy requirements.  As a result, these structures reduce greenhouse gas (GHG) emissions and have a reduced impact on the environment.  This is the revolution that is taking place.

By building highly-insulated, thermal bridge-free building envelopes and by integrating mechanical and electrical systems, heat transfer can be minimized to help maintain constant temperature.  These are crucial characteristics of high-performance buildings, which help to achieve energy efficiency.

Sustainable buildings make economic sense

Industry research shows that sustainable buildings have higher return on investment (ROI) and a faster lease-up rate. * Sustainability is becoming a key attribute for building longevity, and building sustainable, modular high-performance buildings just makes sense:

  • Factory-built modular construction allows to build faster while ensuring superior quality
  • The integrity of specialized building materials is best preserved in a dry factory environment to prevent moisture and mold
  • Testing of envelope and mechanical systems can occur prior to arriving on site, thus reducing risk of re-work to achieve energy modeling certifications

High performance buildings are gaining momentum in North America, and local jurisdictions are pushing towards stricter codes to achieve more efficient buildings and to reduce GHG.  The Province of British Columbia alone has set a goal that all new buildings must reach a “net-zero energy ready” level of efficiency by 2032.

Achieving better performance is possible by incorporating strategies in the building envelope, improving airtightness, and by incorporating building materials and an efficient mechanical system that helps to reduce energy demand.

PASSIVE HOUSE

The Passive House Standard is an International building certification system that reduces energy consumption and greenhouse gas emissions by up to 80%.

Achieving Passive House certification involves specialized modeling and construction techniques designed to drastically reduce the energy required to maintain a consistent and comfortable building temperature.

The basic Passive House concept can be simply explained by comparing a coffee machine with a thermos. The machine requires constant energy to heat and keep coffee warm while a thermos just uses the beverage’s initial heat to keep it hot. In a Passive House building, daylight warming, warmth from indoor lighting, appliances and people occupying the space can provide most of the heat needed.

Simple Shape

Heat loss is minimized by calculating the building’s most energy-efficient footprint.

Superinsulation

Appropriate insulation levels are incorporated depending on climate zone..

Windows

Argon gas-filled, triple glazed with two low-e coatings, set in insulated frames and spacers.

Airtight

Special lining treatment prevents air infiltration and protects against moisture damage.

 

 

Thermal Bridge-free Construction

Prevents heat transfer in key sections of the building.

 

Supply Air Heating

Ventilation uses efficient HRV systems for circulating fresh air and heating recovered air
