i. Release of dangerous gases / materials – Asbestos
What procedures does your firm implement to promote sustainability?
a. Recycling of cardboard, paper and plastics
b. Use of energy efficient lighting and Equipment – LEDs and motion sensor systems
c. Electronic company vehicles i.e Hybrid Mini Countryman
d. Cycle to work scheme
e. Charitable contributions sustainable organisations i.e tree planting / environmental programmes
f. Green initiatives and codes of practice i.e using office space with high EPC / BREEAM ratings
What are some methods of measuring sustainability?
a. BREEAM (Life Cycle Assessment) & EPCs
b. SKA Rating – Commercial property fit-outs
d. Whole Life Carbon Assessments
What is LEED?
a. Leadership in Energy and Environmental Design
b. It is a life cycle assessment
c. It is a USA equivalent of BREEAM
d. The ratings are silver, gold and platinum
What is BREEAM?
a. Building Research Establishment Environmental Assessment Method
What are the benefits of a BREEAM certified building?
a. Lower running costs
b. Minimised environmental impact
c. Greater marketability
d. Increased building value (Green premium)
When is BREEAM used?
a. Sets out the best practice standards for the environmental performance of buildings through specification, design, construction and operation.
b. Assessments need to be undertaken by a licensed assessor.
c. Based on energy, land and ecology, water, health and wellbeing, pollution, materials, waste and management.
d. Applies to new and refurbished projects, domestic and non-domestic
When do you require an EPC?
a. New built property
b. The sale of a property
c. The letting of a property
d. All commercial premises over 50m2
How long is an EPC valid for?
a. 10 years
What EPC requirements for private rented properties are set out in the Heat in Buildings Strategy 2022 update?
Scottish Government plan to introduce regulations in 2025 whereby private rented properties will require an EPC rating of C by 2028 (where feasible to do so).
What is the Paris Agreement?
a. A legally binding international treaty concerning climate change
b. Adopted by a majority of nations and came into affect in 2016
c. The main objective of the Paris Agreement is to limit global warming to below 2 degrees Celsius while targeting levels below 1.5 degrees Celsius when compared to pre-industrial levels by 2025. A decline is require by 2030.
Name some sustainable building methods
a. Use of recycled materials such as reclaimed timber, recycled tiles and plastics
b. Installation of renewable energy sources i.e solar
v. Rain water harvesting
vi. Green roofs
vii. Automatic building systems i.e light sensors
What is a Green Roof and what benefits do they offer?
a. A covering that is made of vegetation that is placed over a waterproof membrane
b. Benefits include absorption of rainwater, additional insulation, increases biodiversity and provide habitats for wildlife as well as being aesthetically pleasing and reducing urban air temperatures
What are Photovoltaics and how do they work?
a. Allow the conversion of sunlight (photons) into electricity
b. When photons hit the solar modules within the solar panel they causes electrons to flow through the bottom layer
c. The movement of electrons generates electricity which flow to an inverter which converts DC electricity into AC.
What is a soakaway and how do they work?
a. A means of controlling the drainage of excess water within the surrounding soil
b. Consists of a large pit or hole which receives water from drainage pipes and diverts it to a drainage location (preferably a reasonable distance away from the property to prevent ground heave / slip)
Can you explain your understanding of the term carbon neutral?
a. Means to have a balance between carbon emitted and carbon absorbed from the atmosphere.
b. It is an important measure of the impact that a business and project has on the environment
What is meant by the term “solar gain”?
a. The increase in temperature of a space, object or structure due to solar radiation.
b. A building can retain solar gain by having high thermal mass or avoid it by using reflective materials and insulation.
How does a ground source heat pump work?
a. Fluid within a loop of pipe which is buried underground is heated by the ground via geothermal heat.
b. The fluid is passed through a compressor that raises it to a higher temperature
c. The fluid is then passed through hot water circuits within the building i.e radiators, how water cylinders etc.
d. Once passed through the system the fluid will cool where it is then passed back through ground loop to be reheated.
What are SUDS?
a. Sustainable Drainage Systems. They allow surface water to be managed as close to its source as possible by allowing surface water to infiltrate into the ground where it is collected and then managed passively.
What are the benefits of rainwater harvesting?
a. Decreases demand for water
b. Promotes both water and energy conservation
c. Improves quality and quantity of groundwater
d. Improves BREEAM compliance
e. Lowers operational costs
f. Reduces a building environmental impact
What is an EPC?
Energy Performance Certificates were introduced in Scotland in 2008 following The Energy Performance of Buildings (Scotland) Regulations 2008.
Once obtained, an EPC is valid for 10 years.
EPCs are rated on a scale of A-G. A being the most energy efficient and G being the least energy efficient.
The EPC will also show the amount of CO2 emissions produced by the property in tonnes.
Why are EPCs required when selling or letting a property?
To comply with the Energy Performance of Buildings (Scotland) Regulations 2008
