Q

What is a CEMP

A

The purpose of a construction environmental management plan is to outline how a construction project will avoid, minimise or mitigate effects on the environment and surrounding area. The basic scope of a plan should consider the following subject areas, as applicable to the individual project; Air quality, Water quality and drainage, Noise and vibration, Geology and soils e.c.t.

Q

What is a BREEAM Assessment

A

BREEAM, first published by the Building Research Establishment in 1990, is the world’s longest established method of assessing, rating, and certifying the sustainability of buildings. BREEAM is an assessment undertaken by independent licensed assessors using scientifically-based sustainability metrics and indices which cover a range of environmental issues.

Q

What are some criticisms of BREEAM

A

BREEAM has been criticised for being ‘tick-box’ in its applicability for example you get points for solar panels but it does not take into account if the solar panels are performing optimally e.g. poor orientation. The score given by BREEAM at the design phase cannot ensure good quality outcomes in the use phase. The outcomes of sustainability measures and low energy technologies could be turned out differently due to the role of the project endusers.

Q

What is an EPC

A

Energy performance certificates (EPCs), set out the energy efficiency rating of buildings. They are required when buildings are built, sold or rented, if they have a roof and walls and use energy to condition an indoor climate.

Q

What buildings do not require an EPC

A

EPCs are not required for the following types of building;Places of worship, Temporary buildings, Stand-alone buildings with a floor area of less than 50 square metres, Industrial and agricultural buildings with low energy requirements, Listed buildings, Rented dwellings that continue to be occupied by the same tenant since before 1 October 2008, Buildings that are suitable for demolition.

Q

What are some criticisms of an EPC

A

The ispection is not invasive only visial meaning the inspector cannot drill walls or ceilings to determine the state or even existence of any insulation.
Issues for listed buildings for example double glazing will not be accepted by english heritage.

Q

What are some of the issues assessed in a EPC

A

The energy survey needed to produce an EPC is performed by an assessor who visits the property, examines key items such as loft insulation, domestic boiler, hot water tank, radiators, windows for double glazing, and so on.

Q

What is a SAP calculation

A

SAP Calculations are a Building Regulations requirement for all new residential developments, conversions and some extensions. The Standard Assessment Procedure (SAP) is a measure of the energy efficiency of a property and is the calculation from which an Energy Performance Certificate (EPC) is generated. These are often called a predicted EPC.

Q

What is a Enviromental impact ratings

A

The environmental impact rating is a measure of a home’s impact on the environment in terms of carbon dioxide (CO2) emissions. The higher the rating the less impact it has on the environment. This rating is based on the performance of the building and its fixed services (such as heating and lighting).

16
Q

What is Land Fill Tax

A

a tax on waste disposal on all landfill sites registered in the UK. The current rate for inert or inactive waste is £2.50 per tonne and contaminated material is taxed at £64 per tonne.

17
Q

What is the Carbon Reduction Commitment Energy Efficiency Scheme

A

Participating organisations are required to monitor and report their energy use each year and to purchase allowances equal to their annual emissions in tonnes of CO2 during each compliance year.

18
Q

What is the Aggregates Levy

A

This is a tax on sand, gravel and rock that’s either been; dug from the ground, dredged from the sea in UK waters or imported. The tax is set at £2 per tonne of sand, gravel or rock.

19
Q

What is the Renewable Heat Incentive

A

Eligible technologies for the non-domestic RHI include; Solid biomass, Ground source heat pumps, Water source heat pumps, Deep geothermal energy, Air-to-water air source heat pumps. and Solar thermal collectors.

20
Q

What is the Feed-in tariff

A

The rate varies from 3.12 to 21.12 p/kWh depending on; The size of the system, The generating technology and the installation date. The United Kingdom’s Feed-in tariff ended to new applicants on March 31, 2019

21
Q

What is Wind Energy

A

A small wind turbine will usually suit an individual household or smallholding and can generate up to 50kW. They are usually up to 35 metres in height, depending on the siting.

22
Q

What does a wind turbine consist of

A

Tower: The main body of the turbine, which is typically cylindrical, and can be up to 75 metres tall.

Rotor blades: Usually a turbine will have between one and three blades made from fibreglass-reinforced polyester or wood-epoxy. They can be up to 80 metres in diameter and rotate between 10-30 times per minute.

Yaw mechanism: This will rotate the turbine to face the direction of the wind.

Wind speed and direction monitor: The wind direction is monitored with sensors and the tower head is turned to face the wind. At very high wind speeds, the turbines will be stopped to protect them from damage.

Gear box: The majority of turbines are fitted with gear boxes but some now have direct drives.

23
Q

What are some advantages to wind power

A

The low carbon nature of wind power. It is a completely ‘clean’ energy, other than the manufacture and construct on of the pylons, blades and turbines.
Wind power generation is relatively silent.
The wind is strongest in the winter months when energy demand is at its highest.
The operational costs associated with wind power are low.
Financial incentives including the feed in tarrif

24
Q

What are some disadvantages to wind power

A

the unpredictable nature of wind speeds resulting in turbines being immobile for significant periods.
It is difficult to store generated power.
Wind turbines tend to be large and very visible within the countryside.
Wind turbines can be a threat to wildlife

25
Q

What are Solar Photovoltaics

A

Solar cells, or photovoltaic (PV) cells, convert sunlight directly into electricity

26
Q

How do Solar cells, or photovoltaics work

A

Photovoltaic cells absorb the sun’s energy and convert it to DC electricity. The inverterer then converts the DV current into AC current from this point the eletricity does 1 of 3 things; stored in a battery tpically lead acid or lition ion with a capcity of 10 kWh, directly fed to appliances or fed through the meter and to the grid where if registered the occupire will receive money from the feed in tariff.

27
Q

What are some advantages to photovoltaics

A
  • Low Maintenance Costs - All that is required is surface cleaning a few times a year
  • Warrenty - Most reliable solar panel manufacturers offer 20-25 years warranty
  • incentives - The government offers many incentives for renewables e.g. feed in tarrif.
28
Q

What are some disadvantages to photovoltaics

A
  • Costs - The upfront cost is rather substantial 1kW £1840, 3kW £5520 & 4kW £6040, batteries are expensive
  • Inefficency - They become inefficent over time especially if they are not miantianed creating a longer payback period
  • space - a large surface area on the roof is required in addition to battery storage
  • Weather dependant - lots of energy in the summer whereas little in the winter
29
Q

What is MEES

A

minimum energy efficiency standards 2020 - are a minimum energy efficiency level for domestic private rented properties, set and enforced by the Government

30
Q

What is the RICS Sustainability Report 2021

A

Thousands of commercial real estate and construction professionals from over 30 countries contributed to the World Built Environment Forum Sustainability Report 2021. Key findings include;

Client, investor and stakeholder demand is cited as the number one driving force behind the recent growth in ESG investments
Two-thirds of survey respondents note rising occupier demand for green and sustainable buildings; almost half report growth in demand for green leases.
Almost two-in-three respondents believe the industry must do more to minimise project waste; less than a quarter see impact on biodiversity as critical.
