Sustainability Flashcards
(77 cards)
Give me an example of sustainable construction ?
“Use of environmentally friendly and recyclable materials.
Retrofitting.
Use of sustainable insulation products.”
What are the challenges of net Zero?
“More than 90% of the country’s current energy provision comes from gas, coal, oil diesel and petrol,
It is not meant to exist in 27 years time.
Although steps are heading in the right direction for decarbonisation, an overhaul of every aspect of lift is required”
What does MEES stand for ?
Minimum Energy Efficiency Standards
Which properties are MEES exempt?
Building not required to have EPC such as industrial sites, non residential agricultural buildings, certain listed buildings, holiday lets etc.
Why is sustainability important?
To preserve the planet and natural resources for future generations
What is sustainability ?
“Meeting the needs of the present without comprimising the ability of future generations to meet their own needs
What are the 3 pillars of sustainability?
“Social - Social sustainability is the ability of society to persistently achieve good social well-being.
Environmental - Environmental sustainability means we are living with the means of our natural resources.
Economic - requires that a buisiness or country uses it resources efficiently and responsibility so that it can operate in a sustainable manner to consistenly produce an operational profit.
What does BREEAM stand for
Building Research Establishment Environmental Assessment Method.
What is BREEAM?
“Environmental Assessment Method was developed by BRE and covers new construction as well as fit outs.
It assessed buildings against various performance criteria and awards credits.
Credits are awarded under Management health and well-being, energy efficiencym transport, water usage, materials, waste, land use, ecology, pollution, innovation.”
The total amount of credits will lead to a rating of unclassified, pass, good, V. good, Excellent or Outstanding.
What is U-value
Value given to a material based on its insulation quality - i.e the time it takes for heat to pass through.
Name some sustainability legislation?
MEES, Climate Change Act etc.
List some local changes you’ve adopted in line with sustainability ?
BNG
What is the Paris Agreement ?
191 countries joined to meet with the aim to strengthn the global response to the threat of climate change
They aim to keep global temperature rise below 2 degrees above pre-indsutrial levels and event try to keep them below 1.5 degrees. Also to use 20% renewable energy by 2050.
What approved docs cover sustainability?
“Part L of the building regulations - Conservation of fuel and power.
Part L aims to achieve net zero carbon buildings or as close to it as possible giving practical guidance on ways of complying with energy efficient requriements.
Overheating
EV charging”
BREEAM thresholds?
“BREEAM Rating % score
Outstanding > 85
Excellent >70
Very Good > 55
Good > 45
Pass >30
Unclassified < 30”
What is LEED?
LEED (Leadership in Energy Environmental Design) is the most widely used green building rating system in the world (USA)
What are the 7 element of a sustainable building?
“Insulation
Airtightness
Thermal Mass
Natual light
Sustainable material
Structural Systems
Renewable technologies.”
Whats sustainable development ?
Economic development that is conducted without depletion of natural resources.
Whats the construction leadership council ?
CLC workd
How can the energy performance of an existing building be improved?
“Insulation
Double glazing
Rated boiler
Use of renewable energy
Sustainable materials
What is embodied carbon?
Considering the carbon that will be used to manufacture a product eg. Sourcing the materials, manufacture, delivery, disposal.
What is the Climate Change Act 2008?
Sets out emission reduction targets within the Uk. It commits the UK to reducing greenhouse gasses by 80% by 2050 but this was updated in 2019 to be net zerio by 2050.
What target in the Climate Act Act was subsequently introduced?
A further interim target was introduced to reduce emissions be 78% by 2030 compared to 1991 levels.
What has the government done to achieve net zero?
“Introducing a 10 point plan for a green industrial revolution which includes items like;
Offshore wind,
greener buildings
green finance
investment in carbon capture storage”
