Sustainability L1 Flashcards
Principles of Sustainable Development
Meets present needs without impacting on future generations
Coal, Oil & Gas
Finite fossil fuels that all produce CO2 significantly contributing to climate change
Environmental sustainability
rates of renewable resources harvest, pollution creation, and non-renewable resource depletion that can be continued indefinitely.
If they cannot be continued indefinitely then they are not sustainable
E.g. use of fossil fuels (oil, coal, gas)
Economic sustainability
the ability to support a defined level of economic production indefinitely.
Social sustainability
liveability
health equity
community development
human rights
labour rights
How national and international legislation, regulations and taxation relating to sustainability affect construction: Climate Control Regulations – Climate change act;
Reduce UK emissions by 26% 2020, 80% 2050
Energy Act 2011;
Tackle barrier to investment in energy efficiency.
EPC rating of F&G not lettable
Carbon Reduction Commitment (CRC);
Improve energy efficiency by encouragement
Kyoto Protocol;
Linked to UN framework binding internationally emission reductions
SKA (RICS);
Non-domestic fit outs,
reduce utility operating costs,
promotes low carbon buildings,
improves occupier engagement
LEED;
Leadership in Energy and Environmental Design
(American based Environment Assessment
Energy Performance Certificates:
All Buildings require an EPC which outlines the energy performance of the property.
Providing indicative costs and what could be done to improve the efficiency of the property.
Display Energy Certificates:
DEC’s display actual energy consumption of public buildings to provide transparency about the energy efficiency of publicly owned buildings.
BREEAM; add example
Building Research Establishment Environmental Assessment Method.
Environmental performance of new & existing buildings.

Building Regs and Codes (sustainability);
standards for design,
construction and alteration works aimed to achieve health,
safety,
welfare,
convenience,
energy efficiency
sustainability.
Building Regs
Part A: Structural Safety
Part B: Fire Safety
Part C: Site preparation and resistance to contaminants and moisture
Part D: Toxic Substances
Part E: Resistance to passage of sound
Part F: Ventilation
Part G: Sanitation, Hot Water Safety and Water Efficiency
Part H: Drainage and waste disposal
Part J: Combustion appliances and fuel storage systems
Part K: Protection from falling, collision and impact
Part L: Conservation of fuel and power
Part M: Access to and use of buildings
Part P: Electrical safety
Part Q: Security: Dwellings
Part R: In-building physical infrastructure
Brownfield sites:
Already developed land that is now derelict land.
Typically requires clearing and/or remediation if contaminated.
Greenfield;
Not previously built on.
Does not need remediation (cheaper to build but harder to get planning).
Encourages urban sprawl
Contaminated land:
any substance which may become harmful to people or buildings.
Corrosive, explosive, flammable, radioactive or toxic.
Typical sources;
chemical works, docklands, landfill/disposal, petrol station.
Clean up type;
1. Excavation, removal and disposal.
2. Limit spread
3. Treatment to Destroy, Remove or Detoxify.
The principles of material resource efficiency within the supply chain
MMC; Greater efficiency realised over the course of the project as elements are put together off site;
less wastage
construction requires less labour,
quicker
reduces H&S risks
Waste Management Plan
Likely waste,
quantities,
who will remove,
location of waste sites,
process of recording waste movement
Recyclable materials
Glass,
paper,
cardboard,
metal,
tires,
textiles,
batteries.
Composting food and garden waste.
