What is it?

Energy efficiency simply means using

ENERGY EFFICIENCY

less energy to perform the same task – that is, eliminating energy waste.

Energy efficiency brings a variety of benefits: reducing greenhouse gas emissions, reducing demand for energy imports, and lowering our costs on a household and economy-wide level.

How?

Energy-efficiency standards are a set of procedures and regulations that prescribe the energy performance of manufactured products, sometimes prohibiting the sale of products that are less efficient than a minimum level

The Laws are made after careful inspection and consideration of the situation the country or region is in. The problem is when laws are replicated without proper context.

Who? Usually Governmental Agencies such as the EPA in the USA make up the laws. In India the Bureau of Energy Efficiency along with parties such as ECBC make up the laws.

Energy Ef ciency Laws

Energy Efficiency rules and laws have to be implemented wherever there is a use of energy even if the energy is sourced from Renewable Alternatives

Collaboration Countries often get together like at the G20 and Paris Summit to talk about how to help bring a balance to the earth and agree on certain rules and regulations which are then implemented at country level.

Energy Efficiency Requirement in Building Codes to provide minimum requirements for energy efficient design and design of buildings and their systems. encourages energy efficient design or retrofit of buildings so that it does not constrain the building function, comfort, health, or the productivity of the occupants. mandates that the building has appropriate regard for economic considerations.

The code sets clear criteria for builders, designers and architects to integrate renewable energy sources in building design through the inclusion of passive design strategies.

North America Since more than a decade and in particular given the increased concerns about climate change, the interest in energy and the built environment has substantially increased.

Moreover, it has become a world-wide concern.

Two typical features for energy issues in the built environment are: 1.The very important role of the individual citizen in taking the appropriate actions 2.The crucial roles of government in setting the scene, typically through legislative measures and/or stimuli.

Here we will be discussing about the Unites States of America

National Energy Code of Canada for Buildings (NECB) Building to meet the NECB will help save on energy bills, reduce peak energy demand, and improve the quality and comfort of the building's indoor environment.

Sustainable, energy-efficient buildings built to the code can also help to 1.improve worker productivity by approximately 5 percent 2.deliver a rental premium of 3 to 5 percent 3.increase sales value between 8 and 26 percent The NECB was last updated on December 18, 2015. NECB 2015 contains more than 90 new changes that will further help to ensure a high level of energy efficiency in new Canadian buildings.

National Energy Code of Canada for Buildings (NECB) The most cost-effective time to incorporate energy efficiency measures into a building is during the initial design and construction phase. It is much more expensive to retrofit later. This is particularly true for the building envelope.

The NECB focuses on five key building elements typically considered during design: Building envelope – Includes walls, windows, doors and roofing, and addresses air infiltration rates and thermal transmission.

Lighting – Measures such as reducing lighting power densities, using lighting controls and making effective use of available daylight are all considered here.

Heating, ventilating and air conditioning systems – Includes heat recovery ventilation, pipe and duct insulation, and building automation and control systems to optimize equipment operation.

Service water heating – Considers all the ways hot water is used in a building and includes requirements to limit water flow rates and maximize waste-water heat recovery, and sets minimum performance standards for service water heating equipment.

Electrical power systems and motors – Establishes requirements for monitoring energy use of electrical distribution systems, sets limits on the size of conductors so as to minimize voltage drop, and establishes standards to govern the

selection of transformers and electrical motors.

ENERGY STAR® Multifamily High-Rise Pilot Program Natural Resources Canada is investing in innovative energy-efficient projects and programs to drive economic growth, contribute to our clean energy future, and create quality jobs for Canadians.

The ENERGY STAR® Multifamily High-Rise Pilot Program will recognize buildings in Ontario that are designed 15% more energy efficient than those built to the provincial building code and other program requirements. It will also help builders adopt energy efficient practices when constructing new mid and high-rise residential buildings.

For builders and building owners, certification means lower operating costs and higher income due to increased rental value. For homeowners and tenants, it means superior energy

performance leading to lower energy costs.

TM DABO DABO is a commissioning software application for fault detection and diagnosis, performance analysis and documentation.

Japan’s Top Runner Programme Japan’s Top Runner Programme, introduced in 1999, is a set of energy efficiency standards for energy intensive products, such as home appliances and motor vehicles. As of 2014, the programme involved 23 product categories.

Products are included due to either their high energy or widespread use or their substantial scope for improving energy efficiency. Energy efficiency targets are set to be achieved within a given number of years on the basis of the most efficient model on the market (the ‘Top Runner’).

The Top Runner sets the standard but takes into account the limits of future potential improvements: standard setting takes into account the potential for technological innovation and diffusion.

Energy Conservation Law / Law on Rational Use of Energy Based on this law, Japan issued a set of building energy standards for commercial and residential buildings called the Criteria for Clients on the Rationalization of Energy Use for Buildings (CCREUB).

Two standards apply to residential building: 1) Design and Construction Guidelines on the Rationalization of Energy Use for Houses (DCGREUH), issued by the Ministry of Construction 2) Criteria for Clients on the Rationalization of Energy Use for Houses (CCREUH), issued by the Ministry of International Trade and Industry and the Ministry

of Construction

Comparison

Design and Construction Guidelines on the Rationalization of Energy Use for Houses The prescriptive-based Design and Construction Guidelines on the Rationalization of Energy Use for Houses (1999), or DCGREUH, includes insulation of the building envelope, HVAC, water heating, as well as guidance on maintenance and operations in its section entitled “how to live.”

The energy code for commercial buildings references three climate zones: ordinary, cold and tropical. Most areas in Japan fall into the ordinary zone.

The energy codes for residential buildings or houses also provide values adjusted for regional and climate differences for insulation-related indictors Climate zones I and II are located in northern areas with cold winters and hot summers, and climate zones V and VI are located in southern areas with warm winters and hot summers.

https://www.kkj.or.jp/contents/english/index.html

Criteria for Clients on the Rationalization of Energy Use for Buildings The CCREUB has requirements for specific building envelope components by climate zone.

The specific components selected receive different scores depending on their impact on energy efficiency.

For example, there are three levels of insulation considered, each with a different score.

The total score of the building envelope is corrected for the location, shape, orientation and function of the building.

Each building must have a total score of at least 100.

Comprehensive Assessment System for Built Environment Efficiency (CASBEE) Comprehensive Assessment System for Built Environment Efficiency (CASBEE) is a method for evaluating and rating the environmental performance of buildings and the built environment.

CASBEE has been designed to both enhance the quality of people's lives and to reduce the life-cycle resource use and environmental loads associated with the built environment, from a single home to a whole city.

Consequently, various CASBEE schemes are now deployed all over Japan and supported by national and local governments.
