Q

What is the Energy Act 2011?

A

Enables the provision and ability to obtain low-carbon energy supplies and creates a fair competition in the energy markets. The Act includes key provisions relating to:

The Private Rented Sector:
The Act also makes it unlawful to rent out residential or business premises that do not reach a minimum Energy Performance Certificate (EPC) rating ‘E’

The Energy Company Obligation:
Requires energy providers to target appropriate measures for households likely to need additional support (e.g. vulnerable people on low incomes and in hard-to-treat housing)

16
Q

How are SAP Calculations made

A

SAP calculations are based on the energy balance of a new development, considering a range of factors that contribute to energy efficiency, such as:

  • Materials used for the construction
  • Thermal insulation of the building fabric
  • Air leakage characteristics of the dwelling, and performance of ventilation equipment
  • Efficiency and control of the heating systems
  • Solar gains through openings in the dwelling
  • The fuel used to provide space and water heating, ventilation and lighting
  • Energy for space cooling
  • Renewable energy technologies
17
Q

Why are SAP calculations important?

A

SAP assessments have been a legal requirement for all new-build, domestic properties in the UK under Part L of Building Regulations since 1995.

Homes must achieve a ‘Pass’ on these calculations for the project to pass Building Regulations.

18
Q

What is an EPC

A

Energy Performance Certificate
It is a legal requirement to have for a building to be constructed,let or sold
They are rated on a scale from A-G (A being the best)

19
Q

How does building control come into EPC

A

Without this, a property will not be signed off by Building Control and may not legally be listed for rent or sale

20
Q

What is BREEAM

A

BREEAM Stands for the Building Research Establishment Environmental Assessment Method.

Sets best practice standards for the environmental performance of buildings through specification, design, construction and operation.

21
Q

What criteria is the BREEAM rating based?

A

The assessment is undertaken by a licensed assessor based on energy, land & ecology, water, health & wellbeing, pollution, materials and waste and management.

22
Q

What are the benefits of a BREEAM certified building

A

a. Lower running costs - more marketable
b. Less environmental impact

23
Q

What are the criteria ratings for BREEAM

A

Ratings are:
Outstanding - 85%+
Excellent. 70-85%
Very Good.55-70%
Good 45-55%
Pass.20-45%
Unclassified. 20% or less

24
Q

What criteria is the BREEAM rating based?

A

Energy, Land use, Water, Health and wellbeing, pollution, transport, materials, waste, management

25
Q

What is the Assessment process of getting BREEAM

A

Design Assessment
Post Construction Assessment

26
Q

What issues did you consider with the design team at the early stages of the design to achieve your BREEAM rating?

A
  • Building orientation
  • Building geometry and layout
  • Solar shading
  • Thermal performance
  • Maximising daylight
  • Providing natural ventilation where possible
  • Airtight building envelope where appropriate to minimise uncontrolled air loss
27
Q

Name some of the BREEAM requirements that would help earn you some credits

A

Thermal model - summer and winter operative temperature ranges in occupied spaces are in accordance

Acoustic Performance - The building meets appropriate acoustic standards and testing requirements

Proximity to local amenities - Food Outlet/Cash Point/Sports facility (2 of) within 500m

28
Q

What does LEED stand for

A

Leadership in Energy and Environmental Design (LEED)

29
Q

What is the RICS Residential Retrofit Standards

A

Effective from October 2024
Creating low-carbon, energy-efficient homes is essential to meeting net-zero obligation
An estimated 25 million homes require a form of energy improvement and professional advice.
This standard will be essential to supporting this work and helping to address one of the biggest challenges facing the built environment

30
Q

What sustainable initiatives are you aware of that are being implemented by the RICS?

A

a. RICS SKA ratings - encourages green codes of practice for commercial properties.
b. ‘Value the Planet’ campaign - committed to forming a climate change expert panel
c. Responsible Business Report - Solutions for companies on how to be greener

31
Q

Name some low and zero carbon technologies that are currently available

A

PV Cells - Convert sunlight into electricity
ASHP - Absorbs heat from the air and to heat water for heaters
GSHP - Similar to above but uses heat from the ground
Wind Turbines - Convert wind energy into electricity

32
Q

What are green roofs

A

A roof covering that is partially or fully covered in plants.
It is placed over a waterproof membrane
They provide habitats for wildlife and are aesthically pleasing

33
Q

What are PV cells

A

Sit on the roof and convert solar energy into electricity

34
Q

What does carbon neutral mean

A

Having no difference between the carbon we release into the environment and the carbon that is captured

35
Q

What is solar gain

A

The term given to using the suns energy to increase the temperature in a space or object

36
Q

What is a ground source heat pump

A
