project scope This project focuses on sustainable living for residential space. The purpose of this rennovation design is to provide a living space on urban fabric as well as sustainable living. Existing builidng location: 47 Bulwer street toronto, On
client study Client : David Suzuki
Career: A leading Environmental Activist, Awardwinning scientist, broadcaster, author, and cofounder of David Suzuki Foundation. Belief: “In our preoccupation with keeping the economy growing, we fail to ask fundamental questions like what is an economy for, how much is enough and what are the important things in our lives.”
concept This residence for David Suzuki is a shelter, protection, and the space that provides oasis of the nature. Approporiate zoning of this residence provides privacy for his study time, as well as public sideallow him to casually invite guests. Landscape design allows dynamic activities. It is a place to enjoy reading, grow your own vegetables, as well as arranging seating sapce according to one’s needs.

LEED (Leadership in Energy and Environmental Design) This particular project’s main concern was to incorporate sustainable design. The next five pages shows how this residential project has possibility of earning LEED certified building.
SS Option D Requirements: A Building that provides shade of 30% total non-roof impervious surfaces. Info: Total Site Area: 3770 Sq.ft
Sustainable Sites: guides one towards selecting the sties in ethnical and sustainable ways.
Total Impervious Area: 1070 Sq.ft Total Gross Floor Area: 1500 Sq.ft Total Green Area: 1800 Sq.ft Calculation: Shading of Non-Roof Impervious Surfaces:
Water Efficiency: focuses on reduction of water usage with low-flow fixtures.
Shade [%] = Shaded Impervious Area [sq.ft] / Total Impervious Area [sq.ft] 42% = 450 sq.ft / 10770 sq.ft 1/2 point Achieved
Energy and Atmosphere: guides towards reducing the building’s impact of energy consumption and its affects on environment.
