INNOVATIVE APPROCH Green efficiency for maximum rating not only demands the highest levels of adherence to energy-efficiency principles but an innovative approach to design and implementation. Briefly, various methods adopted while designing and constructing the building include the following: The external glazing in a commercial building is most challenging in terms of heat gain. To achieve the aesthetic goal and minimise heat gain, external glass with lower-U factor has been used. Substantial emphasis has been given to the design of external glazing for maximum energy-efficiency.

Solar PV plant

Solar panels

A captive solar photovoltaic plant of 132 kWp capacity has been installed on the rooftop. This energy is to be used for common area needs. Further, 100 per cent demand load for this project during operation is from off-site solar energy. * IE – international efficiency which save energy as well as cost. These motor uses consumed electrical energy.

INNOVATIVE APPROCH Intelligent lighting for internal common areas and external lights has been used. Efficiency has also been achieved by the selection of various fixtures, plants, machinery and equipment. Façade elements were meticulously arranged to achieve window-to-wall ratio (WWR). The use of recycled material has been maximised. For instance, broken ceramic tiles (China mosaic) have been used in all terraces as an effective heat gain reducing mechanism. The landscape has been developed according to GRIHA’s guidelines, which include the use of drought-resistant species. Low-noise ventilation fans with IE2-star-rated motors have been used to control noise pollution.

* IE – international efficiency which save energy as well as cost. These motor uses consumed electrical energy.

ORIENTATION FOR OPTIMUM DAYLIGHT

A sun-path design analysis was carried out as the very basis of the orientation of the building. It also provided inputs for sciography analysis and further design. There is no shadow of the adjacent building and the design orientation of the building is in the north-south direction The most important factor – window-to-wall ratio – has been achieved to ensure optimum daylight according to GRIHA guidelines. Further, the north façade of the building has been designed to receive maximum daylight from that direction. The placement of internal equipment, service areas and other utilities has been carefully done so as to attain balance between optimum daylighting and heat gain. The external façade glass has been carefully selected to ensure optimum natural daylight in the interiors.

QUALITY AIR N The air quality at the Milestone Experion Centre is monitored and controlled using CO, CO2, RH sensors, which indicate the levels and provide data for various components of air. MERV13 filters have been used in the treated fresh air system. Low-VOC primer and adhesives used in internal paints and insulation have been carefully selected. What’s more, for HVAC, a green refrigerant has been used. Water (makeup water) for the cooling tower comes from water treated by a sewage treatment plant (STP). The entire system is controlled intelligently through an integrated building management system (IBMS).

GREEN, AND LOCAL! Some green materials used in the construction of the building include: 1.Fly-ash content in PPC cement. Fly ash, otherwise, is a waste product and has high potential to contribute to air pollution. 2. Fly-ash content in cement concrete as per specified guidelines 3. Fly-ash bricks 4.Gypsum for internal wall plaster instead of conventional cement sand plaster. Conventional plaster demands a substantial amount of water for curing, which is saved by using gypsum plaster. 5. Some locally available and recyclable materials used include: 6.Locally available stones for external hardscape works, including Kota stone for internal staircases 7. Aluminium in structural glazing, which is highly recyclable 8..Recycled materials such as broken tiles, wooden panels, shutters, frame, tiles, etc, which are all GRIHA-certified.

ENERGY SAVING OF 40-45 PER CENT Energy-efficient fixtures have been used to reduce energy consumption in the building. Variable frequency drives (VFD) have been fitted with all the pumps and chillers with efficient COP and cooling towers to consume optimized load. All motors of pumps and equipment installed at site are IE2 as per ECBC norms or BEE-star-rated. Additionally, the building envelope has been designed and completed with low-U values to minimize the cooling load. The measures taken have resulted in about 40-45 per cent savings in electric consumption in comparison to the base case. WATER SAVING OF 71.68 PER CENT To conserve water, low-flow fixtures have been used in the project. Rainwater from the terrace is collected and stored in underground tanks for reuse. A surface drainage system with rainwater harvesting pits has been installed to save the groundwater level. An efficient drip irrigation system has been provided to achieve 85 per cent water usage efficiency. Drought-resistant species have been used in landscaping, thereby reducing water consumption. The recycled water is used for the HVAC cooling tower. The total water saving is 71.68 per cent in comparison to the base case. EFFECTIVE WASTE PLAN For waste management, there is an organic waste composter. Color-coded bins differentiate dry and wet waste in every corner of the building. Composting involves the process of naturally occurring bacteria breaking down food waste into high quality, soil-enriching compost for landscaping, gardening, and farming. Further, the building has installed an STP with MBBR technology. Here, a filter press is used to dry sludge, specifically to separate solids and liquids. The treated water from the STP is used for the flushing and irrigation system and the system is designed for zero discharge.

New Logic III – The Tube, the Netherlands This distribution centre in Tilburg is developer DOKVAST’s fifth BREEAM Outstanding building and a local landmark with a futuristic aesthetic. Combining office and warehouse space for occupier RHENUS CONTRACT LOGISTICS, it is designed for future flexibility, with sustainable features including a focus on high levels of airtightness and 11,620 photovoltaic panels. The gas-free logistics centre developed by Dokvast received the BREEAM Outstanding Delivery Certificate with an impressive final score of 99.48%. As BREEAM Assessor, C2N was closely involved in the BREEAM certification process. New Logic III • total surface area : approx 60,500 sqm, • Warehouse: approx 40,000 sqm. • office space: approx 4,500 sqm. • VAL (Value Added Logistics) :16,000 sqm. • VAL can be expanded by another 15,000 sqm..

A Design for the Future A futuristic distribution centre, with round shapes in steel, glass and aluminium, has recently been built right next to the motorway in Tilburg (NL). Developer Dokvast commissioned Habeon Architect to design the highly sustainable building for Rhenus Logistics. The logistics building is a real breath of fresh air compared with the straightforward warehouses that pollute the horizon along motorways and industrial estates everywhere. Remarkable aspects of building DC New Logic III by Rhenus Logistics include the vastness, the round shapes and the large amount of glass for this type of building. Architect Hung Tran of Habeon Architect is responsible for this imaginative design of NewLogic III and was inspired by the location by the motorway. This logistics centre is extremely sustainable in the broadest sense of the word, Not only in its use of materials and energy, but also because it offers a pleasant working environment and can be divided flexibly. The Tube By creating the 290-metre-long south façade alongside the motorway as an elliptical volume from which a spherical shape is cut out, a dynamic image is created that is unique to a logistics building.

Warehouse Behind the dynamic Tube is a rectangular warehouse. A partition wall between the shipping department and the storage section prevents heat or cold from affecting the stored goods. The overall dimensions of the building are 158 x 290 x 18 metres.

Curtain walls The building has large curtain walls to let in as much daylight as possible for a pleasant working environment. The large canopy created by the cut-out in the Tube on the long south side serves as a sun shade for the office and the mezzanine floors behind it. These floors are intended for VAL (Value Added Logistics), where products are labelled, priced, packed and provided with leaflets.

The two elliptical end walls also consist entirely of curtain walls The façade is further clad with a Kalzip standingseam roof system, which allows beautiful curves to be created.

Dynamic interior •

The Tube also has a dynamic interior, with round shapes in walls, furniture and lighting fixtures.

•

An eye-catcher in the entrance hall is the 9-metrehigh steel spiral staircase, designed by Habeon in collaboration with interior designer Maria Tellez. The staircase is finished with a mixed anthracitecoloured stucco solution and has 90-millimetrethick handrails with integrated handles and LED lighting.

•

In the office section, the inside of the ellipse is finished with Derako wooden slats in an invisible support system. By positioning these slats horizontally above each other, the curved shape flows smoothly from the floors to the ceilings.

•

An elliptical reception desk and minimalist annular pendant lamps complete the sophisticated interior design.

BREEAM OUTSTANDING •

The distribution centre was constructed with • sustainable materials, • automatically dimming LED lighting, • triple insulation glass, • extra insulation of roofs and the use of heat pumps.

•

The building has now achieved a BREEAM Outstanding certificate with a super-high score of 98.48%. At the end of 2018, the roof was fully equipped with solar panels. The energy production of the building is now greater than its own consumption. This achievement ensures the building is designed for the future.

• • •

Overview of Green Strategy and Environmental Features With an overall score of 99.4%% on all individual sustainability categories New Logic III delivers an exceptionally high performance. Below the highlights from a number of categories are provided

•

FSC certificate The contractor, Heembouw, disposes of the FSC certification as a result of which all the wood that is used during the construction is FSC certified wood. Also the wood that is used permanently in the building disposes of the FSC quality mark.

•

Awareness energy and water consumption The building is equipped with Modbus meters in the various groups of all main and subdistribution units and the available water meters. These meters are all linked to the DOCC CONTROL platform that allows for the reading of extensive consumption data, as well as the real-time consumption. Because consumption data can become transparent at an exceptionally detailed level, maximum awareness of the user of the building is created. The data are presented in the specifically organized exhibition in the main lobby.

•

Healthy work environment • • • •

The offices dispose of a healthy indoor climate. Apart from the choice for the air conditioning system that contributes to the saving of energy, employees have the possibility of controlling the climate according to their personal needs. The CO2 concentration at the workplaces is measured continuously and, where required, supplemented with additional fresh air. In addition, the workplaces dispose of their own lighting configuration (per 4 workplaces), height adjustable desks, ample natural daylight and the possibility of preventing light nuisance through the installed awning..

•

Attention is not just paid to health aspects at the office. • For instance, the façades of the warehouse were provided with wall-lights that provide for daylight. • These wall-lights were positioned strategically at the center of every aisle, as a consequence the warehouse disposes of remarkably much natural daylight, which contributes to a livable indoor climate.

•

The Trias Energetica principle played a central role in the elaboration of New Logic III. The Trias Energetica principle consists of the following three steps: Step 1: Limit the demand for energy; Step 2: Use sustainably generated energy; Step 3: Where required, use fossil energy as efficiently as possible.

•

Energy saving measures The building was designed air-tight as a result of which as much heat (or cold) as possible remains inside. The latter in combination with the correct insulation value of the façades contributes to reducing the loss of energy to a minimum. The results from the air-tightness tests confirm this picture. This even showed that the office scores at the level of a ‘passive home’.

By setting the standards high, BREEAM assists in making the correct system choice with regard to the cooling installations of our offices. • The architect opt for a sustainable energy system that heats offices. • In this respect they opted for a VAV system (Variable Air Volume system) in combination with an air-heat pump. • This VAV system uses free cooling, which means that in case of a low outdoor temperature and an increasing indoor temperature, the offices are cooled with the “free” cool outdoor air, without the intervention of the heat pump. • A VAV system is an all-air system, which means that in case of more demand for cold or heat, more air is blown into that specific area. • As a consequence the CO2 levels always remain within the safe margins and a contribution is made to a healthy indoor climate. • The complete building was provided with triple glazing. This type of glazing does not only contribute to higher thermal insulation but also to better acoustic insulation. Noise from outside is reduced to a minimum.

•

Generation sustainable energy New Logic III uses sustainably generated energy through the enormous PV installation, consisting of 11,620 PV panels. This renders the building both energy and CO2 neutral.

•

Entirely gas-free Both the warehouse and the offices are heated with an air-heat pump. This renders “The Tube” entirely gas-free and thus a unique building of its kind.

•

Stimulating bicycle usage To stimulate the use of bicycles amongst the staff ample attention was paid to this. For instance, a bicycle lane was installed on the premises and there are no less than three covered and lockable bicycle sheds. In addition, there are changing rooms (M/F) that provide for showers and lockers.

•

Charging points electric vehicles To stimulate the use of electric means of transport several charging points are installed at the parking facilities.

•

Water consumption Rainwater, originating from the roof, is absorbed in tanks. This water is used to flush the toilets. The latter in combination with water-free urinals, valves at the various water consuming groups that are switched off by the motion detectors of the lighting installation and automatic water taps make it possible to reduce the water consumption.

•

Construction The main support construction consists of a recyclable steel frame. In consultation with the constructor the correct grid size and optimisation in the steel construction were sought in order to design both as effectively and efficiently as possible. The steel pillars in the warehouse are protected with collision protection.

•

The foundation of the ground floor of the warehouse consists of a reinforced concrete floor poured in the work. Together with the mixed granulate this floor provides for a stable substructure for the racks and business operations of the user.

•

Building façades Apart from the trendsetting front façade, which is made entirely of aluminium, the façades of the warehouse were provided with sandwich sheeting of Kingspan. By selecting these panels strategically at the centre of every rack aisle the warehouse disposes of exceptionally much daylight, which contributes to a liveable indoor climate in this part of the construction. The LED lighting addresses this handily and is dimmed automatically.

•

•

•

Flexibility The building was set up with attention for flexibility. Due to the selected grid size of the building pillars the user is free to divide the warehouse according to its own needs. With the introduction of an ESFR sprinkler installation, rack sprinklers have become redundant. Changes in the division of the warehouse are thus always possible, without changes having to be made in the sprinkler installation.

•

It was opted to provide the “lost” space above the receive and dispatch area with hollowcore slabs with a maximum span. As a consequence the forwarding zone is pillar-free as much as possible, which prevents the chance of collisions with these parts of the building. Above it, lost space is practically filled through the creation of mezzanine floors where manual order picking activities can take place. In addition, parts of this area are filled as office space, canteen and dressing rooms.

•

Layout / finishing Inside “The Tube” has a high finishing level with ample natural elements. This results in a pleasant and comfortable work environment.
