Net Zero Buildings and Sustainability

-

Note:Indian Green Building Council (IGBC) is working with World Green Building Council (WGBC) in developing a tool for the assessment of net zero energy buildings in the country.

Net Zero buildings

Future Buildings, Green Buildings and Sustainability 

- Net zero can be either Net zero energy buildings or Net zero carbon buildings or both, Zet Zero Buildings

 - Indian Green Building Council (IGBC) would lead the future of net zero buildings in India

 - Future is of net zero buildings and it is also important as government of almost all nations has taken decision to reduce reduce temperature by 2 oC

 -Study on net zero building reveals, there would be huge demand of Net Zero Building professional by 2030 and 2050. As various institutions & organizations have taken decision to develop guidelines for Net Zero Building Certification

 What technicality is required in designing/ developing Net Zero Buildings (energy & carbon)
1. In depth knowledge of the subjects such as

 - Detailed site study - Understand the needs and requirement and how to meet
Study of climate, parameters that affect energy requirement

 - Energy simulation

 - Building Material

 - Use of glass as a strategic measure for Daylight, visual comfort and also to reduce load on artificial lighting

 - Use of lighting, energy and IEQ controls

 - Energy, Lighting, IEQ Standards and Protocols, to optimise energy and provide excellent daylight provision

 - Strategic implementation of Energy Efficiency Measures

 - Energy Optimization

 - Renewable Energy optimisation

 - Building Performance Analysis and Monitoring to diagnose and detect fault in HVAC equipment and also take preventive measures

 - Design for comfort cooling, take measures of thermal adaptation

 - Passive technologies and selection based on site, climate, building type and building use

 - CFD Simulation, how air shall be pumped and quantity to recirculate

 - Close the design loop, design in such a way so that design decision can be met

 - How to built green and carbon neutral

 - Study of energy used in water lifting, usages etc.

 - Water conservation, with respect to energy

 Definition of nZERO Building (nZB)
NZEB generates as much energy as it consumes over the course of a year through the deployment of energy efficient building design and technologies, and generation of on-site energy through systems utilizing solar power, urban waste, biomass, geothermal energy, etc.

At the heart of the net-zero energy building definition is the idea that the building can meet all its energy requirements from cost-effective, locally available renewable energy sources

This initiative was started by BEE and USAID ECO-III to promote NZEBs in India. Objective of nZB is to reduce the demand of power infrastructure in India and to assist policymakers and stakeholders to direct efforts and resources over the next 5 to 10 years so that these could facilitate the development of a NZEB program for the country.

What is adaptive thermal comfort ?

-
Image
Overview Field studies of thermal comfort have been conducted intensively at various climatic locations to define the range of acceptable thermal environment for air-conditioned and naturally conditioned buildings that led to the development of Adaptive Thermal Comfort (ATC) model.  Research on adaptive thermal comfort revealed a higher range of acceptable temperatures, which depend on climate, building type, behavioral controls, and other similar factors. Field studies have also revealed the role of thermal adaptation to conserve energy in air-conditioned buildings, and this concept is also useful for building design, and operation of naturally conditioned buildings as per the outdoor conditions.  Higher bandwidth of comfort temperature and energy conservation opportunities encouraged researchers to carry out intensive field studies of thermal comfort to propose robust adaptive thermal comfort model. Definition Adaptive principle states that if a change occur...

ISO 7730 for Thermal Environment Evaluation

-
ISO 7730 is an International Standard for 'Ergonomics of the Thermal Environment-Analytical Determination and Interpretation of Thermal Comfort Using Calculation of the PMV and PPD and Local Thermal Comfort Criteria’.  ISO 7730 illustrates methods to evaluate the general thermal sensation and the degree of discomfort for occupants exposed to moderate thermal environmental conditions. This Standard grouped the thermal environment into three different categories namely  Category-A,  Category-B and  Category-C  All there  categories  are described with the help of Table given below.  Category-A describes narrow comfort conditions, whereas Category-C prescribes wider comfort bandwidth (-0.7 < PMV < +0.7). The Standard describes the calculation of PMV and PPD indices for thermal comfort and for local discomfort. The Standard also defines the local clothing habits for indoor comfort and but does not provide information for cl...

EN 15251 for Energy and Thermal Environment Evaluation

-
Comfort standard EN 15251 (version released in 2007) is entitled to ‘Indoor environmental input parameters for design and assessment of energy performance of buildings–addressing indoor air quality, thermal environment, lighting and acoustics.’  The Standard EN 15251 deals with energy performance of buildings as well as indoor environment quality such as thermal environment, indoor air quality, acoustic comfort, and visual comfort conditions to provide more comfortable indoor climate and that is also energy efficient.  Previous research  (Nicol & Wilson conducted study in 2010)   has examined that EN15251 Standard helps building designers to optimise the building energy consumption, considering thermal, air quality, acoustic and visual comfort. Furthermore, studies carried out under SCATs (Smart Controls and Thermal Comfort) research project reveal that this Standard involve  only   European countries for energy and comfort evaluation. SCAT s...
