Environment?
Everything Around US..!
Includes all of living and nonliving things which we interact. Includes complex web of relationship that connect us with one another and with the world we live in.

Environmental Problems?
We run more and more earth’s natural resources for economy caused:
Shrinking forest, expanding deserts, eroding soils, deteriorating the agricultural lands, lower atmosphere is warming, melting glaciers, increasing sea levels, more destructive storms, failing water tables, disappearing of sea corals, drying rivers, fisheries are collapsing, extinction of many species.

Sustainability:
Our lives and economies depend on energy from the sun (sun capita) and on natural resources (natural capita) provided by the earth.
Living sustainably means living off the earth’s natural income without depleting or degrading the natural capital that supplies it.

What Keeps Us Alive?
Life is sustained by the flow of energy from the sun through the biosphere, the recycling of nutrients within the biosphere, and gravity.

Major Components:
Living (Biotic)-Plants, animals, microbes.Non Living (Abiotic)- Water, air, nutrients, rock, heat, solar energy.
Some organisms produce the nutrients they need, others get their nutrients by consuming their organisms, and some recycle nutrients back to producers by decomposing the wastes and remains of organisms.

We Depend Heavily on Oil
Oil-The lifeblood of today’s economics may be unaffordable sometime during this century.
Geologist project that known and projected global reserves of conventional oil will be 80% depleted between sometime 2050 and 2100, depending on consumption rate. Natural gas: 60 yrs, Coal: 200yrs (World Energy Council, 2004)
The challenge for this century is to sharply reduce the waste of oil and other resources and to find array of substitutes for oil and other fossil fuels.

We Can Save Money and Energy in Industry
By introducing co-generation system or combined heat and power (CHP) system. Especially for manufacturing that involve heating process where the heat generated is feed back to re-generate electrical for independent use.
Equipments that being used in the system can be replaced by ‘low loss energy efficient equipment such as motors, lightings and air conditioner.
Recycling waste materials from manufacturing also can be a intelligent steps for money saving activities.

Three principal energy objectives are instrumental in guiding the future energy sector development. They are:-
(1/3) The Supply Objective:To ensure the provision of adequate, secure, and cost-effective energy supplies through developing indigenous energy resources both non-renewable and renewable energy resources using the least cost options and diversification of supply sources both from within and outside the country;

LEED, or Leadership in Energy and Environmental Design, is an internationally-recognized green building certification system. Developed by the U.S. Green Building Council (USGBC) in March 2000, LEED provides building owners and operators with a framework for identifying and implementing practical and measurable green building design, construction, operations and maintenance solutions.
![Page 55: EAT446 Environment & Society](https://reader033.vdocuments.us/reader033/viewer/2022061219/54b8ac634a7959fa328b456c/html5/thumbnails/55.jpg)
• LEED promotes sustainable building and development practices through a suite of rating systems that recognize projects that implement strategies for better environmental and health performance.
• LEED is flexible enough to apply to all building types – commercial as well as residential. It works throughout the building lifecycle – design and construction, operations and maintenance, tenant fitout, and significant retrofit. And LEED for Neighborhood Development extends the benefits of LEED beyond the building footprint into the neighborhood it serves.
• LEED also makes business sense, benefiting commercial building owners as well as tenants.

The design and construction of a building which takes optimal advantage of its environment need not impose any significant extra cost as compared to a more highly serviced building. All buildings have a primary function to provide an internal environment suitable for the purpose of the building. The architectural consideration in designing a building is influenced by its responsiveness to the immediate environment. The important factors that should beconsidered include the following:

Orientation and footprint , Climate, region and general availability of natural light , How Buildings Use Energy, Urban vs. suburban , Floor to floor/floor to ceiling heights , Window to wall ratios , Placement of glazing , Toplighting, sidelighting or both , Glazing performance (visible light transmittance, etc.) , Exterior shading and solar control , Interior shading and solar control , Integration with electric lighting systems (lighting power densities, controls and electric lighting design) , Reduced cooling loads (note: discuss cool daylighting) , Interior design (color, reflectance, furniture selection) , Floor plan (how far will daylight penetrate?)

The Basics: Toplighting and Sidelighting
Toplighting brings daylight into the building from above through clerestories, skylights, tubular skylights, sawtooth designs, etc. Daylight that enters the building above 10 feet, even if it's through a vertical opening, is referred to as toplighting.
Sidelighting brings daylight into the building from the side through windows, curtainwalls, etc.
