Site efficiency: where every green-certified building starts
Site efficiency is the set of green certification criteria that assess how a building relates to its land: regulatory compliance, soil protection, accessibility and landscape preservation. It is assessed before materials, systems or construction are chosen, which makes it the starting point of any green-certified project and the first topic in this series.
Why does green certification matter for building owners?
Green-certified buildings deliver measurable financial results. New green buildings report an average 10.5% reduction in operating costs (OPEX) in their first year, and 16.9% over five years.
Those savings depend on decisions made early. Site efficiency is one of the first.
What does site efficiency cover?
At Archetype Group, site efficiency is one of the first areas our experts assess on any project pursuing green certification. It covers four criteria:
- Regulatory compliance: confirming the site and the planned development meet local planning and environmental rules
- Soil protection: limiting erosion, contamination and disturbance during and after construction
- Accessibility: connecting the site to public transport, pedestrian routes and cycling networks
- Landscape preservation: protecting existing vegetation and natural features, and limiting the building footprint

Frequently asked questions
What is site efficiency in green building?
Site efficiency is the group of certification criteria that evaluate a building’s location and land use, including regulatory compliance, soil protection, accessibility and landscape preservation.
When is site efficiency assessed?
It is assessed at the start of the project, before design, materials and systems are fixed, because the site sets the limits for every later decision.

Water efficiency: how green-certified buildings use less water
Water conservation and efficiency is a core criterion of green building certification. It measures how a building captures, uses, reduces and reuses water. A building’s water performance is largely decided at the design stage, long before it opens, which is why it is one of the first areas our experts assess on any project pursuing certification.
How much do green-certified buildings save?
Green-certified buildings can achieve 11% water efficiency, 25% energy reduction and 34% carbon emissions savings through integrated design.
What does a water management strategy include?
At Archetype Group, our water management strategy for certified projects covers four areas:
- Rainwater capture and stormwater retention: collecting rainwater for reuse and managing runoff on site
- Fixture efficiency: specifying low-flow taps, toilets and showers to reduce daily demand
- Landscape design: selecting planting and irrigation that reduce water demand
- Wastewater treatment and recycling: treating greywater and wastewater for reuse where the project allows
Each element is validated against measurable performance outcomes.
Which projects does this apply to?
Since 2002, Archetype Group has delivered more than 1,500 projects across 50+ countries. To date, we have delivered more than 100 certified green buildings worldwide, as part of our commitment to shaping 100% green buildings by 2032.
Our green portfolio covers hospitality, mixed-use, healthcare, office, retail and industrial developments, for multinational and local clients.
Frequently asked questions
Why is water efficiency decided at the design stage?
Fixtures, plumbing layouts, rainwater systems and landscaping are all specified during design. Changing them after construction is costly, so the water performance of a building is largely fixed before it opens.
What water systems help a building earn certification credits?
Rainwater harvesting, stormwater retention, water-efficient fixtures, low-water landscaping and wastewater recycling are the main contributors.

Energy efficiency: what determines a green building’s energy performance
Energy conservation and efficiency is the green certification criterion that measures how much energy a building uses and where that energy comes from. A building’s energy performance is largely set during design, before it is first powered on, which is why it is one of the first areas our experts assess on any certification project.
How much energy can green-certified buildings save?
Green-certified buildings can cut energy consumption by up to 17%, generate up to 15% of their energy on site, and source up to 100% of their electricity as green power.
What are the three factors behind energy performance?
Three factors determine a green building’s energy performance:
- Equipment efficiency: high-performance HVAC, lighting and building systems that use less energy for the same output
- Measurable performance gains: reductions verified against a baseline, not estimated
- Clean power sourcing: on-site renewable generation and certified green power
At Archetype Group, we address all three on every certification project. We verify performance through metering and track it from design through operation.
Who has Archetype Group delivered for?
Since 2002, Archetype Group has delivered more than 1,500 projects across 50+ countries, across hospitality, real estate and industrial developments, as part of our commitment to shaping 100% green buildings by 2032.
Frequently asked questions
How is energy performance verified in a green building?
Through metering. Energy use is measured against a design baseline and tracked after handover to confirm the building performs as designed.
Does green certification require renewable energy?
Certification schemes award credits for on-site renewable generation and for sourcing green power. The level required depends on the scheme and the certification level targeted.

Material conservation: managing waste and sourcing materials responsibly
Material conservation is the green certification criterion that covers two things: how construction waste is managed and how building materials are sourced. On a construction site, every material either goes into the building or leaves as waste. That outcome is often decided before the first delivery arrives on site.
What do green-certified buildings achieve on materials?
Green-certified buildings can divert up to 75% of construction waste from landfill and use up to 20% recycled content, while prioritizing regionally sourced materials to reduce transport-related impact.
How is material conservation applied on a project?
At Archetype Group, we apply material conservation in two areas:
Waste management
We plan to reduce the waste generated during construction and to sort and divert it from landfill.
Material sourcing
We prioritize materials that are:
- Recycled
- Locally sourced
- Reused
- Certified
Each element is validated against measurable performance outcomes.
How does this support certification scores?
From material sourcing to waste management, our teams help clients maximize certification scores on projects for archetype reality and archetype industry, as part of our commitment to shaping 100% green buildings by 2032.
Frequently asked questions
What is construction waste diversion?
Construction waste diversion is the share of site waste that is recycled or reused instead of sent to landfill. Certification schemes award credits based on that percentage.
Why do regional materials matter for green certification?
Materials sourced close to the site travel shorter distances, which reduces the transport-related carbon emissions of the project.

Indoor air quality and wellbeing: how green buildings support the people inside
Office workers in green-certified buildings report 30% fewer sick building symptoms than those in non-certified buildings. A building’s performance shapes its indoor environment, and the indoor environment shapes the health and productivity of the people who use it.
What does green certification measure indoors?
Green building certifications measure indoor environmental performance in two areas: the air people breathe and the spaces that support their wellbeing. Both are set by design decisions made long before the first occupant arrives.
What creates clean indoor air?
- Smoke-free spaces
- Asbestos-free construction
- Fresh air ventilation
- Low-emission materials and cleaning products
What supports occupant wellbeing?
- Access to daylight
- Rest areas
- Fitness facilities
How does Archetype Group design for indoor quality?
At Archetype Group, our experts assess air quality and wellbeing from the start of every archetype reality and archetype industry project. Each element is validated against measurable performance outcomes, as part of our commitment to shaping 100% green buildings by 2032.
Frequently asked questions
What are sick building symptoms?
Sick building symptoms are short-term health effects such as headaches, eye irritation and fatigue that occupants experience while in a building and that ease after they leave. Poor ventilation and indoor pollutants are common causes.
How does ventilation affect green certification?
Certification schemes award credits for fresh air supply above minimum standards, because ventilation directly affects indoor air quality and occupant health.

Innovation in design: better decisions, greater impact
Innovation in green building design means making design decisions that work together to meet certification criteria. It connects every area covered in this series: site efficiency, water, energy, materials, and indoor air quality and wellbeing. Each of these outcomes is set by design before the building opens.
What does innovation in green design look like in practice?
Every part of a certified building is designed to do more with less:
- Water: selecting plants that need less water, reducing lawn areas, collecting rainwater and specifying water-efficient fixtures
- Energy: designing the building envelope and systems to use less energy
- People: green education that helps occupants use the building and its resources responsibly
Why do early design decisions matter most?
Decisions made at concept stage fix the building’s long-term performance. Changing them after construction costs more and delivers less. Integrating environmental criteria from the outset produces resource-efficient buildings with measurable results.
How does Archetype Group approach sustainable design?
At Archetype Group, sustainability starts with design decisions made early. We integrate environmental criteria from the first stage of every project, for archetype reality and archetype industry clients. This is how we work toward shaping 100% green buildings by 2032.
