13
Q
What is your understanding of the term ‘Green Roofs’?
A
- A green roof is a roof covering that is partially or completely covered with vegetation that is place over a waterproof membrane.
- Additional layers such as drainage layers, irrigation systems or root barriers may also be placed over the membrane.
- Rooftop ponds are an alternative form of green roof which are used to treat grey water.
- The vegetation, soil, drainage layer, root barriers and irrigation system are typically the key components of a green roof.
- Advantages of Green Roofs are that they absorb rainwater, provide extra insulation, increase biodiversity by providing habitats for wildlife, are aesthetically pleasing and lower urban air temperatures.
14
Q
What are photovoltaics and how do they work?
A
- Photovoltaics allow the conversion of sunlight into electricity.
- Sunlight contains energy known as photons.
- When photons hit solar modules within the solar panel, they cause electrons to flow through the bottom layer.
- The movement of electrons generates electricity that flows to an inverter.
- The inverter converts DC electricity into AC that is then used to power the building.
15
Q
What is soakaway and how do they work?
A
- Soakaways offer a means of surface water drainage attenuation.
- They consist of large holes or pits that receive surface water from a drainage pipe.
- The soakaway allows the collected surface water to gradually infiltrate through the soil.
16
Q
Can you explain your understanding of the term carbon neutral?
A
- Carbon neutrality is to have a balance between the carbon emitted and the carbon absorbed from the atmosphere in carbon sinks.
- This is an important measure of the impact that businesses and projects have on the environment and global warming.
- To date no artificial carbon sinks are able to remove carbon from the atmosphere at the levels required to off set global warming.
17
Q
What is meant by the term solar gain?
A
- Solar gain is the name given to the increase in temperature in a space, object or structure due to solar radiation, i.e. the heat from the sun.
- A building can retain this solar gain by having high thermal mass or can avoid it by using reflective materials and insulation.
18
Q
How can solar gain be managed in buildings?
A
- Limiting the size and area of openings such as doors and windows.
- Shading or orientating doors and windows from direct sunlight.
- Using reflective materials on the glass and building fabric.
- Insulating walls and roof spaces to prevent indirect solar gains into the building.
19
Q
How does a ground source heat pump work?
A
- Heat from the ground is absorbed at low temperatures into a fluid inside a loop of pipe (a ground loop) buried underground.
- The fluid then passes through a compressor that raises it to a higher temperature, which can then heat water for the heating and hot water circuits of the house.
- The cooled ground-loop fluid passes back into the ground where it absorbs further energy from the ground in a continuous process as long as heating is required.
20
Q
Explain your understanding of SUDS?
A
- The terms SUDS stands for sustainable drainage systems and 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 then managed properly.
- SUDS will slow down surface water run off by allowing it to infiltrate and soak into natural contours and landscapes.
- SUDS are considered to be environmentally friendly as they do not rely on the manufacture of plastic or clay drainage components and instead utilise natural vegetation and material to absorb surface water.
- SUDS rely on a number of management policies, controls and strategies to efficiently and sustainably drain surface water whilst minimising pollution and managing the impact on local bodies of water.
21
Q
What is BREEAM?
A
- Building Research Establishment Environmental Assessment Method
- Sets best practice standards for the environmental performance of buildings through specification, design, construction and operation.
- Undertaken by a licensed assessor.
- Based on energy, land & ecology, water, health & wellbeing, pollution, materials, waste and management.
- Applies to new and refurbished projects, domestic and non-domestic.
22
Q
How many categories are there?
A
- 10 different requirements
23
Q
What are the benefits of a BREEAM certified building?
A
- BREEAM buildings help clients to benefit from lowering running costs of their built assets and minimising the impact on the environment through consideration at planning, design, construction and operation phases.
- Other benefits include greater marketability to building tenants through lower running costs and creating desirable places to live and work.
24
Q
Does BREEAM effect value?
A
- A higher building value and positive PR message is also achieved through the increased sustainability of the building particularly when achieving BREEAM excellent and very good ratings.

27
What is an EPC?
* Energy Performance Certificates were introduced in 2007 and are a legal requirement for a building to be sold, let or constructed. Once obtained, an EPC is valid for 10 years.
* The most efficient built assets typically have the lowest fuel bills are in band A.
* EPC’s are rated on a scale of A-G.
* The energy efficiency of the built asset along with the potential scale after improvements are made are identified.
* The EPC will also show the amount of CO2 emissions produced by the property in tonnes and will advise on the amount this could be reduced by.
* Commercial buildings over 500 sqm. and frequented by the public need to display a display energy certificate (DEC). Based on actual energy used.
28
What sustainable initiatives are you aware of that are implemented by the RICS?
* SKA ratings which encourage green codes of practice for commercial properties.
* RICS has launched the Value the Planet campaign and committed to forming a climate change expert panel to implement the UN’s sustainable development goals.
* RICS has also launched a Responsible Business Report filled with solutions for companies tp operate in a greener capacity, regardless of the firm’s size. This includes introducing higher recycling rates and reducing energy, transport and water use where possible.
