- Mountain Equipment Co-Op
- The new Ottawa store for Mountain Equipment Co-Op is the first retail building in Canada to comply with Canada's C2000 Green Building Standard. This standard relies on energy efficiency, minimal environmental impact, occupant health and comfort and functional performance as the major guiding factors. The building was designed using the...

- Straw Particleboard
- In this paper Straw particleboard trade name Wheatboard was tested by a cabinetmaker. The cabinetmakers found that the product is less coarse than wood fiber particleboard, although the edges required several coats of paint for proper sealing. For woodworkers, the product was lighter than wood fiber particleboard, and was more...

- Low-Emission Adhesives
- This paper discusses the low emission adhesive. Adhesives are widely used in commercial building construction to adhere flooring to sub floors, wall coverings to walls; and to construct cabinetry and furniture. Most adhesives emit dangerous gases because they contain plastic resins. Concern over indoor air quality and worker health stimulated...

- Water-Loop Heat Pumps
- This paper gives details about heating and cooling system that places a heat pump in each building zone. A re-circulating piping system connects the heat pump. The piping system adds or removes heat to the circulating water. This system provides space heating and space cooling for a large number of...

- Radiant Heating & Cooling
- This paper describes about the radiant heating and cooling system to heat and cool buildings that relies primarily on radiation heat transfer. Typically, heated or chilled water is circulated though floor or ceiling panels to condition the space. Conventional radiators have been used for many years to heat buildings. The...

- Low-NOx Burners
- This paper elaborates on the low-NOx burner which is used for commercial and residential space heating is larger in size than conventional burners, although it is designed for ease of installation. When fossil fuels are burned, nitric oxide and nitrogen dioxide are produced. These pollutants initiate reactions which result in...

- Passive Solar Heating
- This paper discusses about the Passive solar heating which works best in small to medium-sized buildings with low internal heat gains, for example, townhouses, arenas, community centers, and low-rise retail and office buildings. The incorporation of moderate levels of thermal mass in the design (for example, concrete floor slabs, masonry...

- Combination Space and Water Heaters
- This paper gives information on Combination space and water heating systems which consist of a storage water heater, a heat delivery system (for example, a fan coil or hydronic baseboards) and associated pumps and controls. The water heater is installed and operated as a conventional water heater. When there is...

- Recuperative Gas Boilers
- This paper discusses and gives information about the recuperative boilers. A requirement of the use of recuperative boilers is that the heating system must be designed to cool flue gas temperatures to achieve condensation. This requires that the inlet or return water temperature is below 50°C. The simplest approach is...

- Direct-Contact Water Heaters
- This article summarizes and gives details about the Direct-contact water heaters which heat large quantities of water for domestic and industrial purposes. Cold mains water enters the top of a heat exchanger column and flows down through stainless steel rings or other device. Natural gas is burned in a combustion...

- Gas Engine-Driven Chillers
- This paper gives details about the gas engine-driven chiller which operates much like a conventional electric chiller, except that an engine is used instead of an electric motor to drive a compressor (screw, reciprocating or centrifugal). These units can use most types of refrigerants. Engine-driven chillers operate at higher efficiencies...

- Alternative Refrigerants
- This paper discusses and gives information about the alternate refrigeration. Until recently, most refrigeration (air-conditioning) systems used CFCs (typically R11 and R12). In addition, foam insulations were installed with CFCs as the blowing agent. As a result of the Montreal Protocol to protect the earth's ozone layer, the use of...

- Cisterns/Rainwater Harvesting Systems
- This paper describes the rainwater harvesting system which is composed of a water-collection system, a storage cistern and a water distribution system. Cisterns should be water tight with smooth interior surfaces. Manholes or other covers should be tight to prevent the entrance of light, dust, surface water, insects and animals....

- Greywater Recycling
- This paper summarizes details about the grey water recycling systems. Greywater recycling technology is most readily applied to new buildings where the ratio of the demand for non-potable to potable water is relatively high (for example, restaurants, laundries, commercial buildings), or where limitations on the availability of municipal water and...

- Greywater Heat Recovery (GWHR)
- This paper gives information about the grey water heat recovery. Buildings which have a significant domestic hot water or process water load may be able to reduce energy costs by utilizing a grey water heat recovery GWHR system. Conventional water heating and plumbing systems do not have the ability to...

- Energy Efficient Appliances
- This paper elaborates about the energy efficient appliances. Refrigerators/freezers, and air conditioners equipped with energy-efficient compressors, motors and heat transfer surfaces; clothes and dishwashers that conserve water and energy. Among household appliances, refrigerators are the largest consumers of energy. Newer refrigerators are equipped with better insulation, improved heat transfer surfaces,...

- Low-Energy Elevators
- This paper discusses about the low energy elevators. A proprietary elevating system has been developed that utilizes an AC, axial synchronous, gearless motor integrated with a traction sheave, brake flange and rotor. This single device hoists an elevator cab up to 10 landings in a fast, smooth movement that requires...

- Sisal Floor and Wall Coverings
- This paper elaborates and gives information about sisal wall and floor coverings. Sisal has been in use as a wall covering for over two decades. Sisal fiber comes from the henequen plant, a cousin of the agave plant, native to Mexico. Sisal farming initially caused great environmental degradation, because sisal...

- Engineered Wood Products
- This paper focused on engineered wood products which are made from strands of wood stripped from low-grade trees such as poplar and aspen (trees grown in 25-year rotations in plantations). The wood strips are bound together with urea formaldehyde-free MDI, and then pressed together to form billets of the desired...

- Warm-Edge Windows
- This paper focuses on warm-edge spacers which either incorporate a thermal break in the spacer assembly or are constructed from a low-conductivity material. There are many designs of warm-edge spacers, but the most effective designs are constructed from polymers with little or no metal content. Besides being a barrier to...
