Q

Are you aware of imminent sustainability updates expected and how will it affect your clients

A

“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”

Q

Are you aware of the future homes standards

A

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

Q

You have identified Part L cost allowances, what do these consist of

Q

What do you understand bio-diversity net gain to be and how is it implemented

A

“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;

  1. Pre development habitat survey
  2. Post development habitat survey
  3. Pre & post habitat data converted into credits
  4. Difference between pre and post habitat data is presented as a percentage”

Q

What is included in a BREEAM assessment

A

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

21
Q

how is sustainability dealt with through the planning system

Study These Flashcards
A

“SEASA
Strategic Environmental Assessment Sustainability Appraisal

process where the local plan considers the best way to improve the three pillars of sustainability

and mitigate negative impacts the plan might have”

22
Q

“What is an EPC

What does it present and when is it required”

Study These Flashcards
A

“EPC - Energy Performance Certificate

It is presented upon completion of a scheme

Is based upon the energy efficiency of the build

Scored A-G”

23
Q

“What is a SAP

When is it required how is it scored”

Study These Flashcards
A

“SAP - Standard Assessment Procedure

Provides forecast energy performance of elements of build 1-100+ higher the number better the performance”

24
Q

What section of building regs deal with sustainability

Study These Flashcards
A

“Part L & Part F

Part L - Conservation of fuel and Power

Part F - Ventilation”

25
Can you advise on sustainable products used in the construction industry and used on one of your schemes
"ASHP - Used in lieu of a traditional boiler a. outside air blown over refrigerant refrigerant warms up turns into gas b. passed through a compressor which adds more heat c. Compressed hot gas passes the heat to water or air"
26
What KPI's do you track for sustainability

"Into the ground Surface water body Surface water sewer or other system Combined sewer"
30
What is the MMC Framework
"Framework of 7 categories for MMC in home building It ranges from off site and near site pre manufacturing to site based improvements It is used to provide builders with better understanding of terminology Enable better access to mortgage, finance and assurance
31
What are the categories of the MMC framework
"1 - 3D primary structural system - Full units pods, can be stacked and loaded 2 - 2D Primary structural system - Timber frame, steel frame 3 - Non systemised primary structure - Timber trusses 4 - Structural and no structural - 3D printing 5 - Non structural assemblies and sub assemblies - Bathroom Pods 6 - Traditional built led labour reduction/ productivity improvements - Brick slips 7 - Site labour reduction/ improvements - Exoskeletons"
32
What initiatives are being introduced for non residential developments similar to future homes and building standards
Future Building Standards to be introduced in 2025. Part L & F introduced in the interim to reduce CO2 by 27% on road to FBS 2025 75-80% reduction
33
What is embodied and operational carbon
"Embodied carbon - The carbon used in the manufacturing process to make the materials Operational Carbon - Is the carbon emitted from the in-use operation of the building"
34
What is the building safety act
Royal assent June 2022 Designed to give residents more power to hold builders and developers to account with toughen sanctions Enhanced regulatory regimes for building safety and construction products Give residents a stronger voice. Applies to buildings that are at least 18 metres in height or have at least 7 storeys and have at least two residential units"
35
What does the building safety act do
"- Ensures clearly identified people are responsible for design, build and occupation of high rise buildings - Building Safety regulator is introduced to hold to account those who break rules - Give residence a stronger voice - Extend rights of compensation to 15 years - Change culture on design and construction to enable high quality safe homes"
36
What is the building safety regulator
"Implement new more stringent regulatory regime Oversee the safety and performance of all buildings Assist and encourage competence among the industry"
37
Why is sustainability so important and why should we be concerned
Global warming Construction contributes to 40% of up CO2 emissions
38
Can you explain what the building regulations are?
Set of mandatory documents that sen minimum standards for design
39
What is Part L what does it include
Part L - Conservation of fuel and power It sets the standards for the energy performance and carbon emissions of new and existing buildings
40
What is Part F - Ventilation
Guidance on building ventilation, including building air quality and preventing condensation in domestic or non-domestic buildings
41
What was code for sustainable homes & what replaced it
Code for sustainable homes was environmental assessment method for rating and certifying the performance of new homes Replaced with technical housing standards to rationalise the many differing existing standards and reduce red tape associated with planning and house building
42
Who benefits from the EPC
Homeowner - Lower bills Client - Can sell as energy efficient
43
What are the building safety acts gateways?
Planning Gateway one – at the planning application stage Gateway two – before building work starts Gateway three – when building work is completed
44
What is building safety act gateway 1
‘planning Gateway one’ introduced via secondary legislation Ensures the consideration of fire safety matters as they relate to land use planning are incorporated at the planning stage
45
What is building safety act gateway 2
Will replace the building control deposit of plans stage, before building work starts, for higher-risk buildings Stop/go point and building control approval must be obtained from the Building Safety Regulator before relevant building work starts must demonstrate how the proposals comply with building regulations requirements
46
What is building safety act gateway 3
At the current completion/final certificate stage when relevant building work is complete Stop/go point, building control approval must be obtained from the Building Safety Regulator before registering and commencing occupation of a higher-risk building Complies with building regulations requirements to provide assurance that buildings are safe to occupy
47
What is a blue roof
A blue roof is a roof that is generally flat is is and designed to retain water above the waterproofs membrane
