Please explain your understanding of the term sustainability?
To meet the needs of the today whilst securing the needs for tomorrow.
(Bruntland Report)
What are Building Regulations relating to sustainability in construction?
What is the main objective of Part L?
To reduce the amount of carbon emission produced by buildings.
How can carbon emissions of buildings be reduced?
What are carbon emissions?
Carbon emissions are the emissions released into the atmosphere, often through human activity such as the burning of fossil fuels such as coal or gas.
Are you aware of any recent changes to Part L?
Part L was reduced down four parts into two volumes: Volume 1: Dwellings and Volume 2: Buildings other than dwellings.
Provision of photographic evidence and reports (insulation depths etc.)
Changes to SAP (Standard Assessment Procedure) calculations with new software.
2023 Part L was updated to remove primary energy factors **as a performance standard. **
This is where energy is converted from primary sources such as oil and coal to a secondary energy carrier (electricity or gas)
Requirement for photographic evidence as part of the final sign-off to show thermal continuity - thermal bridging. (submitted to SAP assessor or building control)
Wastewater heat recovery to all showers.
What is an EPC?
Energy Performance Certificate: legal requirement for a building to be sold, let or constructed.
If EPC is rated as F, are there any exemptions to upgrading?
Yes, exemptions can be applied for via the government website where an account will be made.
- ‘High cost’ exemption
- Wall insulation exemption (if the only relevant improvements for your property are wall insulation)
- Property devaluation exemption (reported by RICS registered valuer)
What are MEES?
The Minimum Energy Efficiency Standards (MEES) Regulations 2018 set a minimum energy efficiency level for domestic private rented properties.
Privately rented properties must have an EPC rating of at least E. The legislation prevents landlords from renting out a property with a rating of F or G.
What are the key principles of sustainability?
How do you incorporate the three pillars of sustainability into your projects?
I consider the appointment of local contractors where possible and local suppliers.
An example of using the three pillars are, when designing the dormer windows at Winckley Square ;
Social aspects: the design contributed towards the protection and enhancement of the Listed Building and Conservation Area.
Economical: The cost for reduced maintenance liabilty.
Environmental: The dormer and windows were designed to achieve the required uvalues with the provision of insulation.
What is the governments net-zero carbon emissions target by 2050?
In 2019, the UK pledged to achieve net zero carbon emissions by 2050 in the country’s drive to end its contribution to global warming.
What is the Future Home Standard?
All new build homes built from 2025 will produce around 75 per cent less carbon emissions than those constructed under current regulations and no longer be reliant on fossil fuels for heating and hot water.
What are the core principles of Planning and Decision making around sustainability?
What are the most common environmental issues experienced on construction sites?
What are the key pieces of legislation that affect sustainability in construction?
This is to assist in the conservation of fuel and power, to prevent waste, misuse or contamination of water and to ensure those in and around buildings are kept safe.
What different code of practice are you aware of for measuring sustainability?
BREEAM ‘Building Research Establishment Environmental Assessment Method’.
SKA Ratings (RICS Environmental assessment method for non-domestic fit outs such as office refurbishments).
What procedures does your firm implement to promote sustainability?
What is the Paris Agreement?
Name some sustainable building methods?
What is your understanding of the term ‘Green Roofs’?
What are Photovoltaics and how do they work?
What is a soakaway and how do they work?
Can you explain your understanding of the term carbon neutral?
Carbon neutrality is to have a balance between the carbon emitted and the carbon absorbed from the atmosphere.
