LEED (Leadership in Energy and Environmental Design) was established and promoted by the U.S. Green Building Council (USGBC). It is currently considered to be the most complete and most comprehensive in various building environmental assessments, green building assessments, and building sustainability assessment standards around the world. The influential evaluation system has become a model for countries around the world to establish their own building green and sustainability evaluation standards.

 

LEED represents the highest benchmark for green buildings, targeting projects that have adopted green building technology applications early in the market. At present, most countries and regions in the world use this evaluation system. It also has been listed as a statutory mandatory standard in some states in USA and other countries .

 

 

 

The newest version of LEED V4 is evaluated based on: sustainable site, water conservation, energy and atmosphere, materials and resources, and indoor environmental quality. The total score is 110 points, and four certification levels are divided according to the corresponding scores: certified, silver, gold, platinum.

 

LEED certified category

At the beginning of the design, Helm put forward the concept of "Halm Home": "zero distance between office and production", "zero distance between design and product", "zero distance between work and life", "zero distance between city and nature". We enjoy smart office in the building and feel the nature when we go out.

halumm Headquarters’ Office Building Be Named to LEED-CI Gold Award

In halumm office building, there are not only office spaces, but also kitchens, guest rooms, gyms, and tea rooms. By adopting eco-friendly construction methods, we create a working environment that not only meets office needs, but also meets the needs of employees' lives and other needs.

 

  

 

Advantage

LEED-CI certification pays more attention to the health of people living indoors. It has extremely high requirements in terms of energy and atmosphere, materials and resources, and indoor environmental quality. On the premise of meeting the LEED certification, halumm adopts  prefabricated interior system to build. The overall control of the project design, material selection, construction and commissioning process can achieve LEED-CI gold certification.

 

Configure Solution

Adopt BIM to realize the integrated design of indoor space, modular design

Design energy-efficient equipment and facilities       

It is planned that 90% of the personnel have independent lighting control, and the lighting power density is 48% lower than the ASHRAE standard

Intelligent equipment (Personnel sensing, automatic light control and lighting situation control)             

Ventilation system volume exceeds ASHRAE standard by 30%      

Monitoring air quality and CO2 concentration  

High efficiency water saving sanitary ware up to 35%          

Green travel facilities

 

Material Selection

Prefabricated interior materials are selected, with modular metal and glass decorative surfaces

Decorative parts are required to be modularized in the factory to achieve zero formaldehyde and VOC release and high efficiency installation

Control formaldehyde and volatile gases in other materials (including paints, sealants, adhesives, composite wood)

The components are required to be disassembled repeatedly and reused for many times to improve the whole life cycle of the product

 

Construction Management

The design team participates in the whole process of construction monitoring, and works closely with the site team

Green construction process management

On-site pollutant management (reduce waste pollution to the environment, prevent pollutants from entering the ventilation system, prevent materials from absorbing VOCs first, space isolation, etc.)

Manage the site operation, low noise, no dust, efficient and fast, improve the health of the construction environment

Comprehensive air quality management and pollution prevention measures were implemented during construction and before settlement

 

Commissioning

Commissioning of electromechanical system (air conditioning and ventilation, electrical, water supply and drainage), air quality testing

Carry out in-depth review of the design scheme and construction submission documents to achieve the expected design effect of the interior space and ensure quality control and operation.

Economize energy: Energy consumption and raw material consumption can be saved by 50%

Air freshening: 50% reduction in carbon and exhaust emissions to the environment

Higher Profit: 50% space saved

High-Efficiency: Saves the construction time, increases the construction efficiency nearly 3 times

Waste Reduction: Dismountable and 95% reusable

Changeable: Optimize interior design and design flexibility

Eco-friendly: No formaldehyde or other harmful gases
