By: Abdallah Alshantaf, Michael Potton, Yassin Thabit, Nisarg Patel, and Kevin Gutierrez

Topics covered – Sustainable Buildings – Certification (LEED) – Sustainable Energy – Building Technologies and Design – Waste Recovery and Usage – Environmental and Global Impact

LEED Certification (Leadership in Energy and Environmental Design)

Why LEED? ● ● ●

Building Generate 35% of greenhouse gases [1]

Construction and Demolition is 35% of landfill waste [1] Internationally recognized standard for buildings [1]

What is LEED? ●

Concerned in the design construction and operation of buildings [1]

●

Different levels and types of LEED Certification

[2]

LEED Certification System How LEED is Obtained: • Point system based on 5 categories [3] • Sustainable Sites • Water Efficiency • Energy and Atmosphere • Materials and Resources • Indoor Environmental Quality

Solar Hydroelectric

Geothermal

Wind

Sustainable Energy Tidal

Biomas s

Zero-Energy Buildings –

Receive approximately 50% of their energy from grid

– –

Generate and return the same amount at a later time

Most common energy extraction methods

– –

Roof-mounted solar Air/ground source heat pumps

Zero-Energy Buildings

Heating Natural Gas

–

Combined Cooling Heating and Power (CCHP) systems

– Electricity

–

Regenerative use of waste heat York University Central Utilities Building

Renovating Existing Buildings

Smart design and technology Parameters to optimize:

– – – – – –

Site potential Energy use Water conservation Building space and materials Indoor environmental quality Operating costs

Passive Solar Design

Example

Example

Scalability

Harvesting rainwater – Incorporate into new and existing buildings – Use of filters to allow for safe drinking – Will reduce demand on ground water

– Could save up to 38% of water used by average household of 4 in Toronto

Greenroofs – Green roofs can be used to grow vegetables – Conserve energy – Reduction of noise and air pollution – Economic incentives –

Can be built for as little as $8-12 per sq-ft compared to 16.75$ per sq-ft for conventional roof

Reducing water waste – Use grey water to irrigate green roofs

– When renewable energy is in peak production and in low demand pump water up to green roof.

– Present savings on monthly water bills
