Sustainable Refurbishment - Coggle Diagram
Sustainable Refurbishment
Effects
Old buildings (no refurbishment)
Solar penetration and glare
Poor control of cooling
Poor ventilation
Poor lighting
New buildings (refurbished)
Improves building's indoor environment quality
Reduces the negative impacts to occupants
Reduces energy consumption utilities and water consumptions
Enhanced value, demand and lower operating costs.
Why?
Due to the increase of energy, water and material resources
Increased need to build, operate and maintain buildings in a more sustainable way
Green Mark for Super Low Energy (SLE)
The framework targets new and existing non-residential buildings
industrial
institutions and schools
commercial/retail
demonstration projects
offices
Aims to encourage industry to push boundaries on energy efficiency
to achieve best-in-class building energy performance in a cost effective manner
Two building categories
Super Low Energy buildings
To achieve at least 60% energy savings
adopting energy efficient measures and onsite renewable energy based on 2005 building code level
Zero Energy buildings
Use of onsite and off-site renewable energy
to generate more than 100% of energy needed for building operation
Green Mark – Leading Green Building Rating System
provides a comprehensive framework
assessing the overall environmental performance of new and existing buildings
promoting sustainable design, construction and operational practices in the built environment
Under the assessment framework
For new buildings
developers and design teams are encouraged to design and construct sustainable green buildings
which can promote
water savings
healthier indoor environments
energy savings
more extensive greenery
For existing buildings
building owners and operators are encouraged to set and
meet sustainability goals in their operations
to reduce adverse impact of
buildings on the environment
occupant health over the building’s lifecycle
Since its launch in 2005, it has helped guide the design, construction and operation of buildings
enhancing environmental performance
increasing energy efficiency
Building Control (Environmental Sustainability) Regulations 2008
Gazetted on 3rd Apr 2008
Purpose: Further improve environmental sustainability of buildings in Singapore
By mandating a minimum standard which certain buildings are required to meet
Leading to...
Improvement in Energy Performance
Requirements are integrated with Building Plan Process
Ensure that buildings operate efficiently throughout their life cycle
QP who submits Building Plan is responsible for assessing & scoring the building based on criteria & methodology (stated in the Code)
Applies to:
NEW buildings
Gross floor area (GFA) of >= 2000 m2
EXISTING buildings
Additions or extensions which involve increasing GFA by >= 2000 m2
Works which involve major retrofitting with GFA of >= 2000 m2
PART IIIB - Environmental Sustainability Measures for Existing Buildings
Introduced to the Building Control Act on 1st Dec 2012
Building owners are to:
Achieve the minimum environmental sustainability standard (GREEN MARK) when installing / retrofitting a cooling system
Carry out periodic energy efficiency audits on the cooling system/s and compliance with design system efficiency.
Submit building information and energy consumption data annually through BCA's Building Energy Submission System (BESS).
Ensure the cooling system continues to operate efficiently through its lifespan
Audit to be carried out by PE (Mech) or Energy Auditor.
Have to be registered with BCA
Audit in accordance to Code on Periodic Energy Audit of Building Cooling System
Applicable to:
NEW buildings
whose planning permission is submitted on or after 1 Dec 2010
1 more item...
EXISTING buildings
Have undergone a major energy-use change on or after 2 Jan 2014
1 more item...
Purpose:
Allow owners to benchmark & gauge their current building operations, in turn enforcing the minimum efficiency standards and allowing the sector to reap the benefits of energy efficient systems.
Super Low Energy Building (SLE Building)
Aim
pushing the envelope of environmental sustainability in singapore
by harnessing cost effective energy efficiency and renewable energy solutions
Super Low Energy Programme
SLE buildings Technology Roadmap
to achieve up to 80% of energy efficiency improvement over 2005 levels
help industry design and develop cost effective SLE buildings
SLE Challenge
encourage the adoption and design of cost-efficient SLE buildings
Keppel Land
Intelligent building control system
High efficiency air distribution system
Air conditioning based on indoor activity analytics
Smart lighting system
Cooling tower water management system
Key technologies and strategies to achieve super low energy
Passive Strategies
Standard good building and design practices as well as as attentively tailored to each specific context
Limited and complicated due to requiring consistent structural and architectural changes to correct the physical features of the building
Assessed case by case
Active Technologies
Mechanical systems
Cooling
Lighting
Plug loads
Smart Energy Management System
Building management system
Control appliances to improve energy efficiency
one example being through tapping on internet of things, advanced sensors, big data analytics, smart technologies have shown potential of saving an estimated 8-18% of total building energy consumption
Through R&D, progress was made in areas such as data driven optimization , model predictive control of multiple systems
