The document describes two zero-energy building projects in Finland: Luukku, a student-designed wooden house that participated in the 2010 Solar Decathlon competition, and Lantti, a prototype Finnish zero-energy detached house designed for the 2020s. Luukku achieved net positive energy production through solar photovoltaic panels and solar thermal collectors. Lantti aims to be a standard detached house with an annual net zero energy balance through energy efficiency measures, own renewable energy production, and the use of sustainable materials and construction techniques. Both projects took a holistic, multidisciplinary approach to achieving very low energy use and net positive energy production.
CEPT University, Ahmedabad - Net Zero Energy BuildingDanfoss India
CEPT (University focuses on understanding, designing, planning, constructing and managing human habitats. Centre for Advanced Research in Building Science and Energy (CARBSE) at CEPT University was established with the aim of providing impetus for research in energy efficiency in built environment and energy resource management at large. CEPT University was one of the top 10 shortlisted finalists for ACREX Hall of Fame powered by Danfoss.
Sustainable Practices
• Insulated wall, roof and floor to reduce heat gain
• Radiant panels and DOAS used for conditioning basement spaces
• Demand controlled fresh air supply based on CO2 sensor
• Combination of radiant panels and VRF for space conditioning for first and second floor
• LED fixtures for ambient and dimmable task lights
• Renewable (PV) Contribution – 34,461 kWh (for 10.5 months)
amount of energy used is equal to amount of renewable energy created on the site
reduce carbon emissions & reduce dependence on fossil fuels
Buildings that produce a surplus of energy over the year are called “Energy Surplus Buildings”
During the last 20 years more than 200 reputable projects claiming net zero energy balance have been realized all over the world.
NZEB buildings consequently contribute less overall greenhouse gas to the atmosphere than similar non-ZNE buildings. They do at times consume non-renewable energy and produce greenhouse gases, but at other times reduce energy consumption and greenhouse gas production elsewhere by the same amount. Traditional buildings consume 40% of the total fossil fuel energy in all over the world and are significant contributors of greenhouse gases.

The vision of Net Zero Energy Buildings (NZEBs) is compelling. In theory, the amount of energy consumed by the building for an entire year should be less than or equal to the amount of energy produced by the onsite renewable source.
The main aim of the project is to build maximum number of floors in the building and make it zero net site energy using roof-top solar photovoltaic (PV) panels. To check weather effect, project is simulated in three different weather conditions.
Defining the Nearly Zero Energy Building – Best practice brochure for municip...MARIA SFYRAKI &ASSOCIATES
5 May 2015. A newly released guideline detailing best practice in low energy building for municipalities has just been released via the EU-funded project known as PassREg. The brochure details inspiring examples from across Europe and provides compelling measures that municipalities can implement for their building sectors. This small book shows how ‘energy efficiency first’ complemented by renewables makes for an ideal approach, not only for municipal energy action planning and in answer to the EU’s call for Nearly Zero Energy Buildings (NZEBs) but also in terms of affordability. All examples detailed are based on the Passive House Standard, an energy standard increasingly being implemented by municipalities worldwide as the basis for achieving extreme energy savings and emissions reductions in the building sector.
In this presentation focus is on definition of Zero Energy Buildings and Net Zero Energy Buildings. Also different aspects of developing Zero Energy Buildings, their advantages and disadvantages have been discussed.

Join us as Finegold Alexander presents the study for the Lowell Trial Court, a 250,000 SF state courthouse designated by Gov. Patrick’s Zero Net Energy Building Task Force as one of three public demonstration projects addressing the challenge of designing public buildings to high sustainability standards.
The engineering components of the study involved proposals for energy reduction and on-site production, investigated through a multitude of computer models and cost-to-benefits charts and analysis. Architecture and architects must change. Architectural form is a critical element in achieving any sustainable goals, including zero net energy. This session will look at the Lowell Trial Court design process and the iterative schemes the team produced. We will discuss building massing, orientation, urban context and all the elements we always address in every project. Now we find our attitudes toward these traditional design criteria are influenced by the integration of sustainable design. Design for zero net energy caused this team to think and collaborate differently with consultants, client and user groups.

2013 Energy Track, Global Trends Driving the Integration of Geospatial and BI...GIS in the Rockies
Urbanization is occurring at an unprecedented rate representing the largest impact humans have had on the planet. Governments are devoting less of their limited funds to capital infrastructure projects and are looking to the private sector to fill the funding gap. This is driving a focus on construction productivity. Worldwide one third of energy usage is used by buildings. Faced with environmental issues many governments are mandating energy-conservation measures for buildings and for infrastructure. These trends are driving investment in technology. In construction which represents 10% of world GDP, the adoption of building information modeling (BIM) has accelerated in the last decade primarily motivated by the need to reduce the risk of budget and schedule overruns. In addition increasingly architects, engineers and designers are realizing the value of integrating geospatial data and technology into the model-based design process. The integration of geospatial not only addresses specific vertical industry problems such as a mandated low carbon footprint, but also enables a more holistic approach to the major challenges of designing more resilient cities.

Architype - Green BIM UK Perspective, NTU Taipei, 13 February 2014Elrond Burrell
Building Information Modelling (BIM) is rapidly becoming the industry standard in building design globally. The UK government has announced that all centrally procured constructions projects need to use BIM by 2016 and expect this to reduce capital cost and the carbon burden from the construction and operation of the built environment by 20%. In Taiwan, the Head of the Construction and Planning Agency (CPA) announce that Taiwan government will support BIM development in public policy.
Architype are leaders in the the field of Sustainable / Green Architecture and are earlier adopters of BIM in their green design processes, particularly with regard to delivering radical reductions in energy consumption & carbon emissions.
Elrond Burrell, Associate at Architype, was invited to present a UK perspective on Green BIM at the National Taiwan University in Taipei on 13 February 2014. The BIM meeting was hosted by Prof. Shang-Hsien (Patrick) Hsieh and held in the Civil Engineering Research Building
Role of Building Automation in nearly zero-energy buildingsLeonardo ENERGY
Building automation (BA) has a key role to play in the implementation of nearly zero-energy build-ings (nZEB). Building automation is the connector of all the single requirements for nZEB, such as a well-insulated and airtight building shell, efficient HVAC system and a high share of renew-able energy. That is one of the main conclusions of a study prepared by Ecofys for the Leonardo ENERGY initiative.
This presentation shortly introduces the functions and potentials Building Automation will have in the transition towards a nearly zero-energy building (nZEB) stock. It also touches on the pathways and actions different stakeholders should take to ensure that the indicated potentials are achieved.
Adopting BIM - An Architect's Perspective (07 May 2014)Elrond Burrell
Slides from a guest lecture presented at London South Bank University, 07 May 2014.
Part 1 - The Wider Context of BIM including UK Government Poilcy
Part 2 - Architype's journey into BIM
Part 3 - Using BIM for Passivhaus Design
These slides use concepts from my (Jeff Funk) course entitled analyzing hi-tech opportunities to look at how improvements are occurring in zero energy buildings. Improvements in the energy efficiency of appliances, in aerogels for insulation, in solar cells for electricity generation, and in passive solar design are helping us reduce energy usage. The goal is zero energy usage of external electricity and fossil fuels.
