Sustainability Flashcards
What are the three pillars of sustainability
“Social – Ensuring there is a local benefit e.g. local labour use investment in schools etc.
Economic – through the use of sustainable technologies it reduces running costs of properties
Environmental – The reduction of carbon emissions and waste”
What are building regulations
Legislation that must be adhered to
Can you name a couple of sections/parts of Building Regs
“Part B - Fire Safety
Part L - Conservation of Fuel & Power
Part F - Ventilation
Part M - Access and use of building”
Are you aware of imminent sustainability updates expected and how will it affect your clients
“Reduction in CO2 emissions by 31% on domestic properties.
Increases Part L & F requirements along with a new Part 0 - Overheating
It will drive capital costs up until the technology and fabric costs adjust to meet demand
It will reduce operational expenditure of the plots and cost to heat”
Are you aware of the future homes standards
Future Homes Standards 2025 are the next step after 2022 improvements a set of standards that will complement the Building Regulations to ensure new homes built from 2025 will produce 75-80% less carbon emissions than homes delivered under current regulations
What is an EPC
Energy Performance Certificate
How often are EPC’s needed
Should be provided at PC and done every 10 years by landlords
You have identified Part L cost allowances, what do these consist of
“This is an assumed scope for an allowance of replacing the existing gas boiler with an ASHP
Or implementation of fabric changes
Triple glazing
Enhanced insulation
Until client is able to define scope we can only make an allowance based on reasonable assumption”
What do you understand bio-diversity net gain to be and how is it implemented
“An approach to development, and/or land management, that aims to leave the natural environment in a measurably better state than it was beforehand
It is measured by;
- Pre development habitat survey
- Post development habitat survey
- Pre & post habitat data converted into credits
- Difference between pre and post habitat data is presented as a percentage”
What is a S.106 through planning
A section 106 agreement is an agreement between a developer and a local planning authority about measures that the developer must take to reduce their impact on the community
What is S.106 money used
They can be used to support the provision of services and infrastructure, such as highways, recreational facilities, education, health and affordable housing
What is BREEAM
Building Research Establishment’s Environmental Assessment Method
It is an environmental assessment method
How are BREEAM developments scored
"Pass >30 Good >45 Very Good >55 Excellent >70 Outstanding >85"
What is included in a BREEAM assessment
BREEAM awards points or ‘Credits’ and groups the environmental impacts as follows
– Energy: operational energy and carbon dioxide (CO2)
– Management: management policy, commissioning, site management and procurement
– Health and Wellbeing: indoor and external issues (noise, light, air, quality etc)
– Transport: transport-related CO2 and location related factors
– Water consumption and efficiency
– Materials: embodied impacts of building materials, including lifecycle impacts like embodied carbon dioxide
– Waste: construction resource efficiency and operational waste management and minimisation
– Pollution: external air and water pollution
– Land Use: type of site and building footprint
– Ecology: ecological value, conservation and enhancement of the site
How is sustainability defined
Meeting the needs of our own without compromising the needs of tomorrow
How is sustainability measured in relation to finished buildings
“EPC
U-values”
what is meant by fabric first approach
“Increased floor insulation
Increased wall insulation
triple glazing
Better U-value doors
Better air tightness”
what is a brownfield site
Former factory/ had development on it
